A power steering lock apparatus provides high reliability and can be actuated using minimal control parts. In a power steering lock apparatus including a lock bolt, an actuator, an actuator driving part, position detecting part, and a slave control part, and being structured such that the slave control part executes a control in accordance with a control signal output by a host control part, the host control part outputs an integrity confirmation code signal to the slave control part, the slave control part executes a computing process by using the input integrity confirmation code signal as a parameter, and outputs a result of computation as an integrity confirmation information to the host control part, and the host control part outputs an engine start signal when the host control part determines that the slave control part is normally activated, and the lock bolt indicates an unlock position state.

Power steering lock apparatus

A drive of a steering-lock actuator is controlled such that a lock member takes a steering lock state from a steering unlock state if there occurs a change in the state of a vehicle door detected by a door-state detecting device and a stop state of the vehicle is detected by a vehicle-stop-state detecting device when an ignition switch is in an OFF state (step S). A power supply to the vehicle-stop-state detecting device is made stop if the ignition switch is turned to the OFF state from an ON state (step S), and the power supply to the vehicle-stop-state detecting device resumes if there occurs the change in the state of the vehicle door detected by the door-state detecting device when the ignition switch is in the OFF state (step S).

Burglarproof device of vehicle

A radar device is configured to transmit an electric wave and receives a reflected wave that is generated by a reflection of the electric wave on an object, and to recognize the object is a potential obstacle that is to be hit by the vehicle when a received intensity of the reflected wave thereby is a specified threshold or more. And, the specified threshold has a plurality of preset values. Accordingly, a determination as to whether or not the obstacle detected by the radar device is the potential obstacle to be hit by the vehicle can be accurately made.

Obstacle detecting control device of vehicle

In an obstacle detecting control device installed in a vehicle body and includes a millimeter-wave radar detecting an obstacle in front of the vehicle and an operation control portion controlling a bake device and seatbelt pre-tensioner according to detection results of the obstacle by the radar, there are provided a detection frequency determining portion determining that a detection frequency of obstacle by the radar within a specified period of time exceeds a first frequency, an excessive frequency determining portion determining that a frequency of the above determination by the detection frequency determining portion exceeds a second frequency, and an indication portion and a warning buzzer to warn a passenger of a change of radar axis of the radar when the above determination by the excessive frequency determining portion is made.

When a &ldquo;window automatic opening mode&rdquo; is set in advance by a window automatic opening mode setting switch ( ), and the user who carries a portable unit ( A) approaches an onboard unit, doors are automatically unlocked, and a window of a predetermined door is opened when the electric field strength of a radio signal from the portable unit ( A) becomes larger than a predetermined value. This function can be disabled by the window automatic opening mode setting switch ( ).
