<p>PURPOSE:To prevent robbery of an automobile and the like by detecting a stop of electric supply to a motor so as to control the electric supply when transfer from an unlocking condition or a superlocking condition to a locking condition is carried out. CONSTITUTION:When a transfer signal to a locking condition is received in a superlocking condition or in an unlocking condition, in a relay circuit 97 and a relay controlling circuit 103, electric supply to a motor 35 is controlled so as to carry out transfer to the locking condition. Then, the motor 35 is rotated, and a brush 94 moves on terminals 91-93, and when the locking condition is accomplished, contact between the brush 94 and the terminals 91-93 is broken, and as a result, electric supply to the motor 35 is stopped while stop detection signals are outputted to the relay circuit 97 and the relay controlling circuit 103. The controlling circuit 103 receiving the signal is set to an electric supply stopping condition and waits the next signal, or set to an electric supply control condition complying with the signal previously given. Just after the accomplishment of the locking condition, transfer to the next condition is possible and it is started again.</p> |
