ON-VEHICLE SECURITY DEVICE

PROBLEM TO BE SOLVED: To provide an on-vehicle security device for automatically switching between a setting that an oscillation/inclination detection signal is not a condition for alarm generation and a setting that the oscillation/inclination detection signal is a condition for alarm generation, without setting operation by a remote control key. SOLUTION: During operation of the security device, an automobile navigation system 2 monitors whether or not a parked vehicle has arrived at a place where the vehicle is oscillated, for example, a multilevel car parking tower, and inputs an arrival signal to a security unit 1 when it has arrived there. The security unit 1 controls the setting that a detection signal of an oscillation detection sensor is not a condition for the alarm generation even in the operation of the security device, if the vehicle might be oscillated while it is parked there and an engine is stopped.
