Electronic steering column lock controller and implementing method thereof

Abstract

The invention discloses an electronic steering column lock controller and an implementation method thereof. The controller comprises a main MCU and an auxiliary MCU, a CAN communication module, an LIN communication module, a key gear connecting line, a vehicle speed connecting line and a lock body state connecting line; wherein, the main MCU receives CAN bus signals and connecting line signals and sends out control signals to an electronic steering column lock actuator; the auxiliary MCU receives the connecting line signals; the main MCU communicates with a CAN bus by the CAN communication module; the main MCU communicates with an LIN bus by the LIN communication module; the key gear connecting line is used for conveying key gear signals to the two MCUs; the vehicle speed connecting line transmits the vehicle speed signals to the two MCUs; and the lock body state connecting line is used for transmitting lock body state signals to the two MCUs. The electronic steering column lock controller can be used for controlling the actuator to carry out the action of opening and closing the lock safely and reliably, thus realizing the theftproof function of deadlocking steering of a steering wheel.

Description

technical field [0001] The invention relates to a motor vehicle steering column lock controller, in particular to a motor vehicle electronic steering column lock controller. Background technique [0002] Present motor vehicle steering column lock adopts mechanical structure usually, mainly contains two kinds of external mechanical locks and internal mechanical locks. [0003] External mechanical locks work by connecting a vehicle's brake pedal to the steering wheel using a long steel bar with a bend at the end. When the steering column lock is locked, the steering wheel cannot be turned at a large angle, nor can the brake pedal be depressed, thus realizing the anti-theft function. The external mechanical lock itself has a certain anti-shear and anti-saw function, but the steering wheel it locks is made of a small aluminum alloy tube embedded in plastic, which is easier to be cut and sawed to form a gap. Taking it out of the notch will disable its anti-theft function. [0...

AI Technical Summary

Problems solved by technology

The steering column lock can overcome the problem of external violent unlocking to a certain extent, but its essence is still triggered by a mechanical device, which cannot avoid the problem that the mechanical key is easy to be copied
