  • Method and device for the controlled driving of a proportionally operated magnetic valve
    Patent number: 6317309
    Abstract: A method and a device for regulated actuation of a proportionally operated solenoid valve are described. The described method and the described device are distinguished by the fact that the actuation of the solenoid valve takes place under consideration for the regulating processes which were necessary prior to such time in order to operate the solenoid valve according to specifications.

  • Method of calibrating of a system which operates depending on a sensor in a motor vehicle
    Publication number: 20010029413
    Abstract: A calibration of a system which operates in dependence on a sensor in a motor vehicle includes testing, with the use of sensors available in a motor vehicle or with the use of data representative of selected conditions or processes or signals of control devices available in the motor vehicle, whether it can be ascertained that nobody is located in a motor vehicle which can influence variables to be determined by a sensor of a system to be calibrated, and performing the calibration when the testing confirms that it can be ascertained that nobody is located in the motor vehicle which can influence variables to be detected by the sensor of the system to be calibrated.

  • Method of correcting the rotating speed of vehicle wheels sensed by wheel sensors
    Patent number: 5299131
    Abstract: Vehicle speed is measured during slip-free travel of the wheels and compared with the wheel speeds to determine correction values which correct for different wheel diameters. The correction values are used to continuously correct the wheel speeds.
