Abstract

A coding method for coding control commands for actuators includes a system that is sensitive to data transmission errors and determines a degree of danger for the system by using a system control unit. A current transmission control command is coded to form a control command code word, by using the system control device, whereby the redundancy of the control command code word depends on the determined degree of danger. The control command code word from the system control device is transmitted to an actuator control unit and decoded to form a receiving control command. The receiving control command is checked for transmission errors and at least one actuator for carrying out the receiving control command is controlled when no transmission error is detected. An actuator control unit conducts the method.

Dependent claims

A coding method for coding control commands for actuators in an automobile system which is sensitive to data transmission errors, the method comprising:

providing a control command to be transmitted to control an actuator;
determining, by a control system, a degree of danger that would be presented to the automobile system by the control command if the control command were transmitted with transmission errors, the degree of danger being determined based on the particular message content of the control command;
coding the control command to form a control command code word by using the control system, a redundancy of the control command code word depending on the degree of danger;
transmitting the control command code word from the control system to an actuator control unit;
decoding the transmitted control command code word with the actuator control unit to form a received control command;
checking the received control command for transmission errors;
and
driving at least one actuator to carry out the received control command when no transmission errors are found.
