This page contains questions and answers about the new requirements for electronic stability control, which take effect from 1 July Electronic stability control ESC is a low cost vehicle crash prevention system that intervenes to help a driver retain control if the vehicle begins to lose traction. ESC works by integrating information from sensors around a vehicle to determine and correct any difference between the intended path of the vehicle and its actual path. If the system determines that the vehicle is not following the path intended by the driver — for example, because the vehicle is skidding out of control — ESC is able to independently control the braking of each wheel, and usually the torque provided by the engine, to bring the vehicle back to the intended path. While there are limits to what it can achieve, ESC is extremely effective in assisting a driver to regain control of a vehicle in an emergency.

Meder, J. How popular is ESC? Main article: Directional stability. Instead, it was frequently bundled Electronic stability control models other features or more expensive trims, so the cost of a package that included ESC was several thousand dollars. Simultaneously, the yaw sensor measures the vehicle's actual yaw rate. Retrieved 5 October It's been more than a decade since electronic stability control was first introduced, and it goes by many names, depending on the company. Department of Transportation". Due to the fact that stability control can be incompatible with high-performance driving, many vehicles have an override control which allows the system to be partially or fully deactivated.

Electronic stability control models version of the Buick Encore scored very well on government crash tests, and those ratings are expected to carry over when testing is complete. ESC estimates the direction of the skid, and then applies the brakes to individual wheels asymmetrically in order to create torque about the vehicle's vertical axis, opposing the skid and bringing the vehicle back in line with the driver's commanded direction. The government mandates that in cars made after Sept.

  • The Allroad features good ground clearance that literally raises it above its A4 predecessor, and offers 51 cubic feet of cargo space within its roomy and comfortable confines for plenty of gear storage.

ESC systems, which are known under a host of other acronyms and various trade names, work by using ABS brakes as a foundation and with the addition of sensors measure steering wheel angle, yaw rate and turning force. Software algorithms interpret the sensor data and determine whether the vehicle is travelling the way it should given the driver input.

If not, the system automatically activates the brakes on one or more wheels or activates the throttle slightly to bring the car back in line. Because rollovers are frequently preceded by evasive maneuvers--particularly steering and braking--ESC provides the ability to avoid the loss of control and prevent subsequent rollover. However, ESC systems were not introduced on the most rollover prone vehicles until years after luxury models received the feature.

ESC makers blame auto manufacturers for failing to offer the equipment as standard and packaging the feature with other "luxury" items as a high-cost options. Further erosion of potential ESC applications may occur as manufacturers "decontent" vehicles for cost reasons, removing essential foundation equipment like four-channel ABS brakes and equipping models with systems that will require significant upgrades in order to add ESC controls.

Supplier also appear to be exercising caution in their external marketing as their customers are loath to see a system promoted that highlights rollover problems with their vehicles.

The newest ESC systems are more sophisticated than ever and include vehicle roll rate sensors and other anticipatory features to actively prevent scenarios that are likely to lead to a rollover crash. ESC's first iteration was essentially traction control that developed in the late s by BMW and used the engine control system to reduce torque in "stability critical" situations.

BMW recognized the tendency of drivers to "overreact and lose control" and developed systems that actively worked to prevent these problems. At this time published technical papers describe testing and document improved vehicle controllability using ESC systems.

In Mercedes began using ESC systems in production. This system was designed by Toyota and major components supplied by Aisin and Denso. By technical papers continued to describe testing of ESC systems and their development and BMW began talking about its 3rd generation design. During Mercedes advertisements included descriptions of its ESC as a feature that "stabilises the vehicle electronically" and "remains on standby to control the car if and when the driver loses control.

Stabilitrak was later adapted to a number of other GM vehicles. During tests in Denmark a journalist rolled a fully loaded A-Class at 37 mph in what is commonly referred to as the "Elk" or "Moose" avoidance maneuver. In response Mercedes announced it would retrofit the A-Class with ESC as well as new tires and suspension components to prevent rollover. In addition Mercedes stopped production and changed the design. At the time a Daimler spokesperson said "the company had little choice.

As Daimler-Benz and Mercedes-Benz, we have to go over the top. Following the A-Class flap, industry trade journals reported in that both Ford and VW were clamoring to get ESC on their lower priced models and ESC was first added to vehicles with four-wheel-drive. One of the vehicle manufacturer concerns that arose at this stage was the supply base was being quickly being consumed as component suppliers began showing signs of difficulty meeting demand--especially for company's who were late to bring ESC into their models.

Bosch, an early leader in ESC technology published a paper in describing five years of experience with ESC systems in production. They cited crash data from Germany that 20 - 25 percent of all car crashes with injuries and fatalities resulted from loss of vehicle control vehicle spinning and 60 percent of those crashes were single vehicle.

The authors claimed this stemmed from the difficulty drivers face when attempting to control their vehicle in limit scenarios and the tendency of drivers to steer too much, worsening the situation. To resolve these known problems their ESC was designed to help the driver control the vehicle, particularly in panic maneuvers as the primary task of the ESC is to limit slip angle and prevent vehicle spin, which helps to prevent the driver from steering too much.

As ESC became more sophisticated and less costly, many of the vehicle manufacturers continued market research and found that when consumers were presented with ESC capabilities they included the feature high on their list of "product wants. For dozens of makes and models offered ESC either as standard or optional equipment and a study, co-authored by a German Ford engineer, evaluating the European Accident Causation survey data found ESC had a positive influence on the total number of loss-of-control crashes.

This study was followed by several others by Toyota and Mercedes that also found crash data supported the contention that real-world crashes were being reduced in vehicles with ESC. More recently a study from Sweden and simulation results from the U. This is a particularly important because of the past history with "smart" technology like ABS brakes. Following the widespread implementation of ABS, studies showed that these safety systems were not reducing crashes and in some types of conditions vehicles with ABS were experiencing greater numbers of single vehicle crashes.

These findings left NHTSA and other safety organizations feeling "burned" by their strong recommendations of the first "smart" technology. The ABS problem also left researchers looking for reasons why a system that performed well under test track conditions was not showing improvements in the real world. While most concluded the problem stemmed from driver interaction and the failure of vehicle manufacturers to properly educate consumers about the need to simply depress brakes and hold as opposed to pumping , it is likely the on-road problems were due in part to low-cost, low-performance designs that flooded the market.

Concerns now abound within the top-tier ESC suppliers that low cost, low-performance systems are likely to find their way into the market, which will dilute the positive real-world performance data. High rollover risk vehicles like passenger vans, which began to catch the attention of safety regulators and federal safety officials in , were among the last vehicles fitted with ESC. Even after prodding from the NTSB to use ESC on these models Ford, the market leader in this segment, added more warnings and announced it wouldn't add the feature until In addition to normal ESC features, RSC measures the degree and rate at which the vehicle's body is leaning and if it senses a rollover is about to occur, the system is activated.

The roll sensor also activates the seat belt pretensioners and triggers the side curtain air bags. Even as light trucks are increasingly moving to lower, wider designs that appear to be less rollover prone, ESC will likely remain an important active safety feature. Newer designs are even incorporating algorithms to address issues like trailer sway in the event the vehicle is towing.

This page contains questions and answers about the new requirements for electronic stability control, which take effect from 1 July Electronic stability control ESC is a low cost vehicle crash prevention system that intervenes to help a driver retain control if the vehicle begins to lose traction. ESC works by integrating information from sensors around a vehicle to determine and correct any difference between the intended path of the vehicle and its actual path. If the system determines that the vehicle is not following the path intended by the driver — for example, because the vehicle is skidding out of control — ESC is able to independently control the braking of each wheel, and usually the torque provided by the engine, to bring the vehicle back to the intended path.

While there are limits to what it can achieve, ESC is extremely effective in assisting a driver to regain control of a vehicle in an emergency. International research indicates that ESC has the potential to reduce loss-of-control crashes by between 20 and 30 percent.

The number of light vehicles up to kg with ESC entering the New Zealand fleet is increasing, which is expected to prevent deaths and serious injuries over the next two decades. Making ESC mandatory will ensure all light vehicles entering the fleet are fitted with ESC, which is expected to prevent a further 22 deaths and serious injuries.

Its goal is a safe road system increasingly free of death and serious injury. This requires a forgiving vehicle fleet that helps to reduce or avoid error, recover from error and absorb crash forces. As ESC is proven to reduce the risk of crashes as a result of driver error, the Safer Journeys Action Plan included an action to mandate ESC for all light passenger and commercial vehicles entering the fleet.

Most used vehicles imported into New Zealand come from Japan. Although most recent models in Japan have ESC, many older vehicles do not.

Used imports will be required to have ESC from later dates to ensure enough suitable vehicles will be available for the New Zealand market. ESC is an inexpensive feature and has little effect on the price of a new or used vehicle. The requirement for imported used vehicles will be introduced later to ensure that enough vehicles are available. The overall supply of vehicles is unlikely to be affected but, for a short time, there may be restrictions on particular models.

Vehicles fitted with ESC may have an indicator light on the dashboard and often have a switch to temporarily disable or reduce the influence of the system which may be useful if the vehicle is stuck in mud or snow. The requirement only applies to vehicles imported into New Zealand after the change comes into force. Vehicles already in the fleet will not be required to have ESC. However, if your vehicle does have ESC it will need to be maintained in good working order.

This will be checked at warrant of fitness inspections. ESC systems are tailored to the precise characteristics of a vehicle at the time of manufacture and cannot practically be retro-fitted.

The draft amendment Rule, overview document and questions and answers were released for public comment on 11 March The consultation was advertised in major daily newspapers and in the New Zealand Gazette. The NZ Transport Agency received 30 submissions on the proposed changes, which were taken into consideration in finalising the Rule.

This is an amendment Rule and, therefore, contains only the amending provisions. A copy of the final amendment Rule will be available for purchase from selected bookshops that sell legislation or from Wickliffe Solutions, telephone A newsletter outlining the Rule changes will be sent to the groups and individuals who have registered their interest in the Light-vehicle Brakes Rule. The NZ Transport Agency will advise relevant industry groups of the changes.

Where required, the NZ Transport Agency will update factsheets and other information about new and used light motor vehicles. What is electronic stability control ESC? How does ESC work?

What are the safety benefits of ESC? Is ESC mandatory in other countries? Why will used imports be required to have ESC from a later date? Will mandatory ESC affect the price of cars? Will mandatory ESC affect the supply of cars? How can you tell if a vehicle has ESC? Can you retro-fit a vehicle with ESC? How has ESC been mandated? Was the public consulted on the changes to the Light-vehicle Brakes Rule? What issues were raised by submitters? This has been addressed by drafting an exception to the fitting requirement for certified LVVs that are manufactured, assembled or scratch-built in quantities of or less in any one year, and where the construction of the vehicle may affect compliance with any vehicle standards prescribed by law.

Submitters advised that some vehicle suppliers would have difficulty meeting the proposed implementation dates for Class NA vehicles utes and vans , and suggested later dates.

However, it is unlikely that any such difficulties would significantly affect the overall availability of utes and vans to customers. As the safety benefit of ESC is at least as great for utes and vans as for passenger vehicles, they have not been given different implementation dates.

As a result the relevant dates for implementation were changed for both new and used vehicles. New vehicle requirements will now be applied based on the date the vehicle was certified for entry into service and used vehicle requirements will be applied based on the date the vehicle was inspected at the border for use in New Zealand.

In addition, the proposed introduction dates of 1 January , and for used vehicles were changed to 1 March , and in order to avoid difficulties caused by the implementation falling in the middle of a holiday period. Does the amendment Rule give me all the information I need to fully understand the changes? How can I obtain a copy of the amendment Rule?

Where can I get more information? How will the Transport Agency ensure people know about the amendment Rule?
