Outputting the safety control signal according to the second driving signal SOLB output by the microcomputer 1 when the vehicle speed detection determination unit 3 determines that the vehicle speed is not detected regardless of the driver's will. The unit 4 generates a safety control signal, and the shift control signal output unit 5 logically combines the generated safety control signal with the first and second drive signals output by the microcomputer 1 to the shift drive unit 6. Output the shift drive signal.
