Electronics Stability Control
P407- ELECTRONICS STABILITY PROGRAM
Instability may arise through inappropriate speed, emergency situations or other unexpected conditions. Such circumstances can be especially hazardous for vehicles, where even momentary loss of control could lead to potential rollover situations.
Electronic Stability Control is the generic term for systems designed to improve a vehicle's handling, particularly at the limits where the driver might loose control of the vehicle.
The system contributes enormously to improving safety by monitoring key stability parameters and automatically triggering appropriate controls. It is designed to work on wet or slippery roads (the aim being to loss of control resulting from either oversteer or understeer conditions) and on dry roads (where the main risk is roll over resulting from excessive speed or adverse camber on bends).
The system has sensors that measure lateral acceleration at the vehicle's centre of gravity. If this force exceeds a predetermined limit, the engine torque is cut and wheel brakes are applied. ESP cannot override a car's physical limits. If a driver pushes the possibilities of the car's chassis and ESP too far, ESP cannot prevent a crash. It is a tool to help the driver maintain control.
The system is able to detect driver reaction by comparing the yaw angle with the steering angle. If these do not correspond, engine torque is cut and wheel brakes applied to stabilise the vehicle. Precisely which brakes are activated (on which wheels and which axles) depend upon the nature of the instability.
Robert Bosch GmbH were the first to deply an Electronic Stability Control system, called Electronic Stability Program (ESP®) that was used by Mercedes-Benz. It was then introduced to the mass market by Continental Automotive Systems under the broader name of Electronic Stability Control, which is now the more common term recognized by the Society of Automotive Engineers, although individual motor manufactures use a range of different marketing names .
ESP combines anti-lock brakes, traction control and yaw control (yaw is spin around a vertical axis). To grasp how it works, think of steering a canoe. If you want the canoe to turn or rotate to the right, you plant the paddle in the water on the right to provide a braking moment on the right side. The canoe pivots or rotates to the right. ESP fundamentally does the same to assist the driver.
Numerous international studies have confirmed the effectiveness of ESP in helping the driver maintain control of the car, help save lives and reduce the severity of crashes. In the fall of 2004 in the U.S., the National Highway and Traffic Safety Administration confirmed the international studies, releasing results of a field study in the U.S. of ESP effectiveness. NHTSA concluded that ESP reduces crashes by 35%. The prestigious Insurance Institute for Highway Safety later issued their own study that concluded the widespread application of ESC could save 7,000 lives a year. That makes ESP the greatest safety equipment development since seat belts, according to some experts.
Vehicle manufacturers use electronic stability control systems under different marketing names:
Acura: Vehicle Stability Assist (VSA)
Audi: ESP - Electronic Stabilization Program
BMW: Dynamic Stability Control(DSC), inluding Dynamic Traction Control
Cadillac: All-Speed Traction Control & StabiliTrak
Buick: StabiliTrak
Jaguar: Dynamic Stability Control (DSC)
Lexus: Vehicle Stability Control (VSC) and Traction Control (TRAC) systems
Volvo: Dynamic Stability and Traction Control (DSTC)
Ford: AdvanceTrac
GM: StabiliTrac
Toyota: Vehicle Stability Control (VSC) and Vehicle Dynamics Integrated Management (VDIM)
VW: Electronic Stabilitization Program (ESP)
Mercedes: Electronic Stability Program (ESP)
Cadillac: StabiliTrak
Chevrolet: StabiliTrak (except Corvette - Active Handling)
Nissan: Vehicle Dynamic Control (VDC)
Mini Cooper: Dynamic Stability Control
Mercury: AdvanceTrak
Hyundai: Electronic Stability Program
Honda: Electronic Stability Control (ESC)

Electronic Stability Control forms the foundation for news advances on vehicle equipment that will save additional lives and give the driver still more control over the vehicle. The computing power of ESP facilitates the networking of active and passive safety systems on the car, creating the opportunity to address still more causes of crashes.
