VEHICLE ANTI-THEFT DEVICE Russian patent published in 2022 - IPC B60R25/00 

FIELD: automotive industry.

SUBSTANCE: anti-theft device of the vehicle contains an authorized access sensor made in the form of an electromagnet coil (1) with a core (6), a spring (4), a cushion (3) and a frame (2) of the driver's seat, a notification and control unit (7), a sensor switch authorized access. The core (6) is placed under the cushion (3) of the driver's seat spring-loaded to the frame (2). The spring (4) is made plano-convex with the possibility of free running of one of its ends and is placed on the support plate (5) installed between the coil (1) and the frame (2) of the driver's seat. The coil (1) of the electromagnet is connected in series with a rectifier (8), a comparator (9) and an amplifier (10) at one end, and with a pulse generator (11), a delay line (12), a timer (14) and a circuit break switch at the other end (15). The comparison device is additionally connected to the weight selection resistor (16), and the logic element (13) is connected to the unauthorized access warning system (17). In this case, the delay line (12) is connected to the amplifier (10).

EFFECT: authorization of the driver of the vehicle is achieved using its weight.
