The invention relates to a device for sensing vehicle invasion. The device comprises a sensor part provided with an RF sensor for sensing activities in a vehicle, a glass window broken sensing sensor for sensing the break of vehicle glass windows, and an inclined sensor for sensing inclined variable quantity of the vehicle, a control part for determining whether the vehicle is invaded or not based on electric signals received by the sensor part and sending corresponding control signals, and a warning part for sending warning information or starting a police whistle of the vehicle, aiming at the control signals received from the control part. According to the invention, the vehicle invasion is sensed by using the RF sensor, the glass window broken sensing sensor and the inclined sensor. Compared with a conventional device only by using an ultrasonic sensor, the RF sensor and the inclined sensor, the device provided by the invention can objectively determine whether the vehicle is invaded or not. Besides, according to the invention, electricity consumption can be reduced; a driver can aware that the vehicle is invaded and cope with the invasion immediately; and convenience is accepted.
