Abstract
An active hydraulic system for a motor vehicle, which active hydraulic system comprises a supply pump, a number of valves to control the actuators, and a measuring device to determine the movement parameters of the vehicle. The components of the active hydraulic system follow a process for the recognition of cornering for a vehicle. To achieve this, the components of the active hydraulic system measure signals and accordingly adjust and alter the ride of the vehicle. The process includes measuring a vehicle acceleration signal a and comparing the vehicle acceleration signal a to an acceleration threshold value a.sub.s. A vehicle velocity signal v is then compared to a lower vehicle velocity threshold value v.sub.u. The process further includes comparing the vehicle velocity signal v to an upper vehicle velocity threshold value v.sub.o. A steering movement which is measured as a value of s.sub.delta, is detected as a steering angle below and above a steering angle threshold value s.sub.delta. When the velocity of the vehicle is between the lower and upper vehicle velocity threshold values v.sub.u and v.sub.o, respectively, the power supply of the actuators is then actuated only if the actual acceleration simultaneously increases above the acceleration threshold value a.sub.s.
