摘要： A method for controlling the brakes in an automotive vehicle. The vehicle has a velocity and a plurality of wheels, each wheel having an angular velocity and a brake which is operable by applying a pressure agent to the brake. An amount of the pressure agent to be applied to, or released from, each brake, individually, to implement a desired braking operation is determined. Switching times corresponding to the amounts of the pressure agent are calculated for opening and closing the inlet valve or outlet valve of each respective brake, individually. An estimated vehicle velocity and an estimated wheel angular velocity which result from applying the pressure agent to the brakes are determined. The actual velocity of the vehicle and the actual angular velocity of the wheels are determined by measuring the angular velocity, and determining the velocity based on the measurement. A comparison is performed, either between (1) the actual velocity and the estimated vehicle velocity, or (2) the actual angular velocity and the estimated wheel angular velocity. The amounts of the pressure agent to be applied to, or released from, each respective brake are adjusted, based on the comparison.

摘要： A control process for controlling the driving stability of a motor vehicle is provided. The difference between the actual value of the yaw rate and the desired value is measured in a control process to form the additional yawing moment for stabilizing the vehicle. Instead of using yaw sensors for the direct measurement of the yaw rate (yaw angular velocity), two lateral acceleration meters are provided in the sensor. Advantageous variants include the use of the yaw acceleration and/or its derivative as the controlled variable, instead of the yaw rate.

摘要： A system for controlling the yaw rate of a vehicle is provided. The system includes a facility for measuring the yaw rate, the lateral acceleration and the reference velocity of the vehicle. The velocity of the side slip angle of the vehicle is determined according to the equation: ##EQU1## where .beta. is the velocity of the side slip angle, a.sub.trans is the lateral acceleration, .nu. is the reference velocity, .gamma. is the yaw rate, .nu. is the time derivative of the reference velocity, and .beta. is a side slip angle. The velocity of the side slip angle determining mechanism includes a mechanism for setting the value of the time derivative of the reference velocity to zero, and a mechanism for determining the side slip angle by integrating the velocity of the side slip angle.
