Patent ID: 7131051

Claim:
A coding method for coding control commands for actuators with a system sensitive to data transmission errors, which comprises the following steps: determining a degree of danger of a current transmit control command to the system by using a system control; coding the current transmit control command to form a control command code word by using the system control, a redundancy of the control command code word depending on the degree of danger to the system passed by the current transmit control command, critical control commands for controlling the system being coded to have a higher redundancy; transmitting the control command code word from the system control 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; driving at least one actuator for carrying out the received control command when no transmission errors are found; storing in the system control all transmit control commands previously transmitted to the actuator control unit; and compressing the current transmit control command and the transmit control commands previously transmitted to the actuator control unit by using the system control before transmitting the current transmit control command and the transmit control commands previously transmitted to the actuator control unit.
