Anti-skid regulation (ASR) and electronic stability programme (ESP)
The anti-skid regulation (also known as Traction Control) optimises traction to prevent skidding of the wheels, by acting on the brakes of the driving wheels and on the engine.
The electronic stability programme acts on the brake of one or more wheels and on the engine to keep the vehicle on the trajectory required by the driver.
