  • Publication number: 20200319297
    Abstract: The present disclosure relates to a method for detecting a malfunction of at least one environment sensor of a motor vehicle operating while the motor vehicle passes a predefined gate region of a road network. Detection data is determined based at least in part on sensor data from the at least one environment sensor. A deviation of the detection data from reference data is determined. The reference data describes at least one object actually present in the gate region. An entry regarding a malfunction of the at least one environment sensor is stored when the deviation fulfills a predefined indicator criterion.

  • Publication number: 20200318661
    Abstract: A method for operating a hydraulic valve of a hydraulic device of a motor vehicle transmission device, wherein an actuating current of the hydraulic valve is superposed with a modulation alternating current in order to adjust a shaking vibration of the hydraulic valve by a control device, wherein a deviation between an actual pressure resulting from the actuating current and a setpoint pressure determined as a function of the actuating current is determined for the hydraulic device by means of an electronic computing device, and an amplitude and/or a frequency of the modulation alternating current is increased as compared to a starting value equalizing a hysteresis of the actual pressure relative to the setpoint pressure, as a function of a tolerance range being exceeded by the determined deviation.
