ESP can actively control the rotational speed of the engine, and the adjustment of each wheel driving and braking forces, to correct the vehicle oversteer and understeer. Actually the ESP system isa kind of traction control system, but with other traction control system, esp not only control the drive wheels, and can control the driven wheel. As a rear wheel drive car oversteering, esp will slow braking lateral front to stabilize the car out of control, prevent the rear wheel and drift phenomenon; in turn over an hour, in order to correct the vehicle tracking direction, esp will slow brake i
