A control device operates a vehicle hydraulic brake system (a) in a fallback mode during which a simulator isolating valve is closed and a brake circuit isolating valve is open, (b) in a simulator mode during which the simulator isolating valve is open and the brake circuit isolating valve is closed, and (c) to transition from the fallback mode to the simulator mode using an intermediate mode in which, at least once, the simulator isolating valve and the at least one brake circuit isolating valve are simultaneously closed for a first time interval, the simulator isolating valve and the at least one brake circuit isolating valve are simultaneously open for a second time interval, and the simulator isolating valve is closed for a third time interval, while the at least one brake circuit isolating valve is open at least part of the time during the third time interval.

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.

A method and an apparatus for regulating the speed of the low-&#x3bc; wheel as a vehicle starts from rest or accelerates on a road surface having adhesive friction values that differ between the left and right sides of the vehicle (split-&#x3bc;), the low-&#x3bc; wheel being braked by braking intervention when it has exceeded a defined slip threshold. In order to improve the acceleration behavior of the vehicle, it is proposed to regulate the speed of the slipping low-&#x3bc; wheel to a defined setpoint speed during a setpoint speed regulation phase in which the setpoint pressure for the brake of the low-&#x3bc; wheel is set so that the wheel tracks the setpoint speed; to discontinue setpoint speed regulation when the high-&#x3bc; wheel meets a defined breakaway condition; to initiate a setpoint pressure control operation during a setpoint pressure control phase in which the setpoint pressure of the low-&#x3bc; wheel is abruptly reduced in order to decrease the drive torque transferred to the high-&#x3bc; wheel; and lastly to continue setpoint speed regulation.

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

The invention is based on a method and system for regulation and/or control of an automobile chassis where between the vehicle body and at least one wheel there is at least one actuator actuated by actuation signals for exertion of forces between the vehicle and the at least one wheel. At least parts of the actuation signals are so formed that the vertical movements of the vehicle body will be damped inertially. According to the invention, at least parts of the actuation signals (Fij) are so formed that the damping takes place dependent on the magnitude of the vertical velocity (Zaij') of the vehicle body.
