A method monitors a sensor clock signal in a sensor unit, which is generated and output for a data transfer between the sensor unit and a control unit with a predefined period duration. A reference clock signal having a predefined reference period duration is received. The sensor clock signal is compared to the reference clock signal. Based on the comparison, a deviation of the current period duration of the sensor clock signal from a target period duration is detected. Based on the detected deviation, a counting pulse or a reset pulse is emitted.

Device and method for monitoring a sensor clock signal

A method corrects at least one transmission parameter for data transmission between a sensor unit and a control unit. A sensor timing signal is generated by a sensor oscillator with a predetermined period. The at least one transmission parameter is determined on the basis of the sensor timing signal. A reference timing signal is generated by a reference oscillator with a predefined reference period. The sensor timing signal is compared with the reference timing signal. A deviation of a current period of the sensor timing signal from a reference period is determined on the basis of the comparison. The at least one transmission parameter is corrected on the basis of the determined deviation.

Device and method for correcting at least one transmission parameter

A device for monitoring a voltage supply for a vehicle system includes a self-diagnostic function which evaluates a logic state of the comparison signal which is output by a comparison device as a function of an input signal, and checks whether a reset signal which corresponds to the output comparison signal is generatable. The self-diagnostic function recognizes a malfunction of the comparison device when the evaluated logic state of the comparison signal does not match an expected logic state. The self-diagnostic function recognizes a malfunction of the reset device when the checked logic state of the reset signal does not match an expected logic state.
