ABSTRACT:
In an anti-theft system for a vehicle, a tilt signal generating device outputs a tilt signal based on a tilt of the vehicle. A characteristic sensing device receives the tilt signal and detects a characteristic of the tilt signal. A computing device computes a change of a parameter based on the characteristic of the tilt signal. A state estimating device estimates a parking state of the vehicle based on the change of the parameter. A determination rule setting device sets a determination rule based on an estimation result of the state estimating device. A determining device generates an operational signal when the determining device determines that there is fear of theft by comparing the tilt and the determination rule. A warning device informs the fear of the theft of the vehicle based on the operational signal.
