Patent ID: 7906867

Claim:
A power steering lock apparatus comprising: a lock bolt which is movable between a lock position at which the lock bolt is engaged with a steering shaft, and an unlock position at which the engagement is released; an actuator moving the lock bolt; an actuator driving part driving the actuator; a position detecting part detecting an operating position of the lock bolt; and a slave control part controlling the actuator driving part; wherein when a host control part which is mounted on a vehicle and outputs an engine start signal by detecting an operation of a switch for starting the engine outputs a control signal to the slave control part, the slave control part executes a control in accordance with the signal, characterized in that: the host control part outputs an integrity confirmation code signal to the slave control part by detecting the operation of the switch, the slave control part executes a computing process by using the input integrity confirmation code signal as a parameter, and outputs a computing result together with the lock bolt position information input from the position detecting part as an integrity confirmation information to the host control part, the host control part determines based on the input integrity confirmation information whether or not the slave control part normally operates, and outputs an engine start signal when the slave control part normally operates and the lock bolt position information by the position detecting part indicates the unlock position state, wherein the computing process of the integrity confirmation information includes a command for executing a control inputting the lock bolt position information from the position detecting part and transmitting the lock bolt position information to the host control part, wherein the slave control part executes the computing process of the integrity confirmation information in parallel with the process obtaining the position information of the lock bolt from the position detecting part.
