Vehicle Stability Control (VSC)
How does it work?
VSC checks twenty five times every second where the driver is steering the car, and the actual track the vehicle is taking. When it detects that a skid or slide is starting, it instantly applies a correction via the traction control and ABS system that will help correct the situation without further input from the driver.
VSC cannot increase the available traction, but maximises the possibility of keeping the vehicle under control and on the road during extreme manoeuvres, by using the driver’s natural reaction of steering in the intended direction.
It is suggested through research in Sweden, Japan, the USA and Germany that the type of loss-of-control accident the system is designed to counter can be reduced by between 22% and 35% with the fitment of VSC.
The component parts of the system are:
- Four individual wheel speed sensors
- Electronic Control Unit (ECU) and hydraulic modulator
- Steering angle sensor to monitor the driver’s steering input
- Yaw rate sensor
- Lateral acceleration sensor
- Instrument panel light and audible warning to show system has intervened
Customer benefits
- Safer day-to-day driving, helping the driver maintain control
- Confidence that the car can react more quickly than the driver in the event of an emergency
