A method for determining a variable representing a hydraulic pressure drop across a valve of a brake circuit, in which a control pulse, designed such that abrupt braking pressure changes are suppressed, is applied to the valve, and in which the hydraulic pressure drop across the valve is determined from the knowledge of the control pulse.

In a first region of the driver's braking command, regenerative braking produces almost all of the braking torque, whereas the friction brake produces essentially no braking torque. In this region of the braking command, the pressure medium flowing into the wheel brake cylinder as a result of the driver's actuation of the brake pedal, is conducted by appropriate control back to a storage chamber. The first region is limited by a threshold brake pedal travel which corresponds to the maximum braking torque available from the motor. When pedal travel exceeds this threshold, the friction brake and the motor both effect braking.

Only the brake pressures at the front wheels are controlled individually. For this purpose, the speeds of rotation of the front wheels are detected. The brake pressure at the rear wheels is controlled jointly for both rear wheels and no detection of the speed of rotation is provided at the rear wheels. However, the brake line leading to the rear-wheel brakes has inserted into it a 2/2-way valve which can be moved into its shut-off position as a function of the brake-force distribution determined as a function of the loading and then holds the rear-axle brake pressure constant.

Anti-lock control with rear brake pressure limitation

A system for chassis control, specifically of passenger cars and trucks, where the control parameters of the controlled loop are varied for control of the chassis properties in contingence on the state of travel of the vehicle as determined by sensors. Specifically determined for recognition of the state of travel are parameters representing the vertical-dynamic state of movement of the vehicle and/or the individual driving style of the operator. This procedure is based upon the relative movements between the vehicle body and at least one wheel, captured by sensors.

System for chassis control

A pneumatic suspension intended for motor vehicles that is equipped with an additional volume. An adjusting piston defining the additional volume separates two work chambers from one another, which can be disconnected from one another or made to communicate with one another via a connecting line and a valve assembly in the connecting line. When the work chambers are in communication, the spring rate of the suspension is variable without force.
