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 method for ascertaining a useful signal. The method includes a sampling a read-in sensor signal using a first sampling frequency in order to obtain a first sampled signal and sampling the sensor signal using a second sampling frequency in order to obtain a second sampled signal, the first and the second sampling frequency differing from one another. The method further includes a step of detecting the useful signal as signal components of the first and the second sampled signal, the signal components of the first and the second sampled signal having the same frequency within a tolerance range.

Method and device for ascertaining a useful signal

A control unit for a restraint system in a vehicle, including an evaluation and control unit and at least one external ignition circuit interface to which a squib for activating the restraint system is connected via a go-line and a return line, the evaluation and control unit cyclically ascertaining, by measuring, an instantaneous ohmic loop resistance of the corresponding ignition circuit and comparing this with at least one stored threshold value. The evaluation and control unit determines an instantaneous temperature in the vehicle interior, close to the time for the measured value detection for ascertaining the ignition circuit loop resistance, the evaluation and control unit carrying out a temperature compensation of the ascertained ignition circuit loop resistance for the go-line and return line of the connected ignition circuit based on the instantaneous temperature in the vehicle interior, the go-line and return line being situated outside the control unit.
