摘要:
In a vehicular anti-theft security system which includes a theft detection sensor (2, 3) that detects an abnormality of the vehicle associated with vehicle theft, and performs a theft preventing operation when the theft detection sensor detects the abnormality, an altitude measuring device (1) is provided for measuring the altitude of the vehicle, and a controller (5) restricts the theft preventing operation in the case where the altitude measuring device (1) observes a specified change in the altitude of the vehicle within a specified period of time when the theft detection sensor detects the abnormality. Selected Figure: FIG. 2
摘要:
A vehicle theft prevention system switches an engine from an immobilized state to a mobilized state when an ID code received from a mobile device (20) carried by a user matches an ID code registered in advance, and keeps the engine in the immobilized state when the ID code received from the mobile device (20) does not match the ID code registered in advance. Further, when a disable command is received from the center and it is detected that the vehicle is in an unused state based on a state of a predetermined signal indicative of states of the vehicle, the system immobilizes the engine and prevents the engine from being switched from the established immobilized state to a mobilized state even if the ID code included in the signal received from the mobile device (20) matches the ID code registered in advance by invalidating the ID code of the mobile device (20).

摘要:
A steering lock driving circuit includes: a microcomputer (30) that, based on a detected condition of a vehicle, outputs one of a lock command for restricting rotation of a steering shaft (25) by a rock member (21) to carry out steering lock and an unlock command for releasing the steering lock; a latch circuit (311) that, when an unlock signal indicating that the lock member (21) is located in an unlock position is input to the latch circuit (311), holds the unlock signal; an OR circuit (313) to which a logical NOT signal of a signal output from the latch circuit (311) and a parking signal indicating that a shift position is a parking position are input; and an AND circuit (314) to which one of the lock command and the unlock command, a signal output from the OR circuit (313) and a condition coincidence signal generated when information detected from the vehicle satisfies a predetermined condition are input.

摘要:
A moving object detection system includes a transmitter, a receiver, a detector, an oscillation means, a switch and a controller. The oscillation means is configured to generate a first oscillation signal having a first frequency, and a check signal having a check frequency that is different from the first frequency. The switch is configured to supply the first oscillation signal or the check signal to the detector. The controller has a monitoring phase and a check phase and is configured: to supply the first oscillation signal to the transmitter through the switch at the monitoring phase; and also to supply the check signal to the detector through the switch at the check phase.
