A method for operating a brake system of a vehicle. A precontrol value for a brake pressure of the brake system is set by using an admission pressure value representing a admission pressure in the brake system and a processing specification representing a braking dynamics of the vehicle.

Method for operating a brake system, and brake system

A method for detecting the clutch condition in engine-powered vehicles. To ensure a reliable detection of the clutch condition even in extreme driving situations, the engine torque of at least one vehicle engine is increased or reduced automatically by pulses and the response of the engine to the torque pulse is evaluated.

Method for detecting the clutch condition

A method of stabilizing a vehicle equipped with a slip-controlled brake system is described. This is done by determining the wheel speeds of the individual wheels of the vehicle. For at least one wheel, a wheel speed setpoint is determined. For the at least one wheel, a deviation quantity describing the deviation between the wheel speed determined for that wheel and the setpoint is determined. To stabilize the vehicle, actuators assigned to the at least one wheel are activated as a function of this deviation quantity.

A panic braking operation of a vehicle having at least two wheels is detected by measuring speed quantities which represent the rotary motions of at least two wheels, selecting the speed quantity of one of the wheels and/or by determining a speed value from the speed quantities, determining a change value which represents the time-related change of the selected speed quantity and/or of the speed value, determining the time characteristic of the change value, and detecting a panic braking operation as a function of the time characteristic of the change value. What is advantageous here is that no complex and expensive additional sensor technology is needed for detecting panic braking; the wheel-speed sensors which are provided anyway in anti-lock control systems, traction control systems, and/or vehicle stability control systems are sufficient. Thus, the use of a panic detection is also possible in so-called &ldquo;low-cost braking systems&rdquo;.

Method and device for detecting a panic braking operation

A method or apparatus for controlling a braking system in a vehicle, the vehicle including an inside front wheel and outside front wheel, whereby a determination is made of whether a drifting and/or an oversteering condition exists; and, if so, a predetermined braking pressure is applied to the outside front wheel.

Vehicle steerability and driving stability while braking in a curve

A method and device for detecting cornering of a vehicle, or for ascertaining the transverse acceleration (a ) of a vehicle, where a signal indicating cornering of the vehicle, a measure of the curve radius, or the transverse acceleration (a ) of the vehicle is detected, using a reference speed (v , v , v ) for at least each side of the vehicle; and where a reference speed (v , v , v ) of one side of the vehicle is determined as a function of the deceleration of at least one wheel on this side of the vehicle.

Method and device for detecting cornering of a vehicle

A method and a device for adjusting a braking action at wheels of a motor vehicle are described. In response to a detected &mgr;-split situation, a reduction of the braking action at a low wheel of a rear axle is brought about as a function of a reduction of the braking action at a same-side wheel of a front axle. One variant of the method and device no braking action is applied to the low wheel of the rear axle. As a result of the two variants, the low wheel of the rear axle, which is at a side that has a lower coefficient of friction and does not significantly contribute to the overall braking action, is rendered virtually without brake pressure and can therefore function as a reference variable, i.e., vehicle reference velocity. As a result, especially in light commercial vehicles, the braking distances are shorter in response to braking actions in a &mgr;-split while maintaining stable driving performance during the entire braking action.

Method and device for adjusting the braking action in a motor vehicle

An instability value for at least one wheel is derived from the detected variables such as rotational velocity of the wheels, and as a function of this instability value, the brake systems are actuated to change the brake pressure, such that in addition, the present invention can calculate a variable which modifies or represents the driving dynamics of the vehicle and wherein the instability value can be modified as a function of the calculated driving dynamics variable.

System for actuating a brake system

In a brake system with a controllable hydraulic pump in a hydraulic circuit, and with at least one solenoid valve, the operating state of the valve is changed in response to a control signal. As a result of the change in the operating state of the solenoid valve, the flow resistance in the hydraulic circuit is changed. Monitoring structure is provided which, in the presence of certain operating conditions, monitor the run-down behavior of the hydraulic pump in different operating states of the solenoid valve and actuate a display device to display a malfunction of the brake system when a malfunction is detected. Additionally, or alternatively, the automatic brake control can be turned off in reaction to the detection of a malfunction. It is possible for the control unit and the hydraulic unit to be replaced separately and for the installation to be tested for proper functioning.
