The present invention relates to an arrangement for monitoring the driving condition of a vehicle, having means for generating a steering angle signal (L) and means for generating a transverse acceleration signal (a), means being provided for comparing a signal derived from the steering angle signal Lto a maximum steering angle signal, means being provided for comparing a signal derived from the transverse acceleration signal (a) to a maximum transverse acceleration signal, and a variable (F) that describes the driving condition of the vehicle being derivable from the comparison. The present invention also relates to a method of monitoring the driving condition of a vehicle.

Assembly and method for monitoring the driving condition of a vehicle

A method is described for monitoring wheel speeds, having the following steps: determining the wheel speeds, determining the wheel having the maximum wheel speed, determining the wheel having the minimum wheel speed, determining the differential speed between the maximum wheel speed and the minimum wheel speed, and comparing the differential speed to a threshold value, if the differential speed is greater than a threshold value, the wheel having the maximum wheel speed being registered as the fastest wheel and the wheel having the minimum wheel speed being registered as the slowest wheel, in event of a change of the wheel speeds, so that another with wheel is the fastest wheel and/or another wheel is the slowest wheel, the fastest wheel being registered and the slowest wheel being registered and a logical status being established from the registered values and the instantaneous values. A device for monitoring wheel speeds in accordance with the above method is also described.

Method and device for monitoring wheel speeds

A method for compensating the offset of a pressure value having the steps: detecting a pressure value, lowpass filtering of the pressure value, storing the lowpass filtered pressure value as an offset value, the lowpass filtered pressure value being stored as an offset value if at least the condition is present that a logical signal has or assumes a first value and a substitute value is stored as an offset value if the logical signal has or assumes a second value. Also described herein is a device for compensating the offset of a pressure value.

A method for monitoring wheel speeds, having the following steps: Determining the wheel speeds (S ), determining the wheel having the maximum wheel speed (S ), determining the wheel having the minimum wheel speed (S ), determining the speed difference between the maximum wheel speed and minimum wheel speed (S ), and comparing the speed difference to a threshold value (S ), deep snow or road conditions of comparable effect being inferred if the speed difference is greater than a threshold value and the slowest wheel has changed exactly once and the fastest wheel has changed exactly once or the slowest wheel has not changed and the fastest wheel has not changed and the speed difference between a driven axle and a non-driven axle exceeds a threshold value.

Method and apparatus for monitoring wheel speeds

A method for monitoring a braking system contained in a vehicle. The braking system includes at least one brake circuit. The brake circuit, on the output side, contains valve configurations, to which wheel brake cylinders allocated to the brake circuit are connected. The braking system furthermore has at least one pump capable of delivering braking medium to at least two wheel brake cylinders. During predetermined vehicle states, the at least one pump is actuated and the first valve configurations are driven by predefined driving signals. Ascertained for at least one wheel of the vehicle during the actuation of the pump and the first valve configurations is a wheel-performance variable which describes the wheel performance, in particular the wheel-rotation performance, of the corresponding wheel. The braking system is checked for a first and/or second fault as a function of this wheel-performance variable.

Method and device for monitoring a braking system contained in a vehicle

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.
