Problems solved by technology

[0003] At present, most common electronic steering column lock control methods on the market control the electronic steering column lock ESCL through the keyless system controller PKE and the body controller BCM. However, due to the different design characteristics of each system, many automotive electronic steering column lock control systems The reliability of the car is not particularly high, which also lays a hidden danger for the realization of the car anti-theft function.

Abstract

The invention discloses a control method of an electronic steering column lock, and belongs to the field of automatic control of automobiles. The method adopts a PEPS (Passive Entry Passive Start) controller and a BCM (Body Control Module) to respectively control the anode and the cathode of an ESCL (Electronic Steering Column Lock) power supply, the PEPS adopts a main MCU (Micro Controller Unit) and an auxiliary MCU to respectively and independently control the ESCL to supply electricity. Meanwhile, a redundant signal transmission mechanism is adopted, and an LIN bus and a physical hard line are used for carrying out contrast detection on the lock tongue state signal of the ESCL. As the control method has the characteristics, the control method of the electronic steering column lock can ensure the high reliability and safety of actions of the automotive electronic steering column lock and therefore provides an antitheft function for vehicles. Moreover, the control method is suitable for vehicles in all fields.

Description

technical field [0001] The invention belongs to the field of automatic control of automobiles, and relates to an electronic steering column lock control method. Background technique [0002] With the rapid development of my country's automobile industry and expressways, it is becoming more and more important to research and develop controllers related to vehicle safety and anti-theft control. The steering mechanism (steering wheel) locking device is one of the nationally recognized anti-theft devices, and its quality, reliability and safety are particularly important. Traditional mechanical steering column locks are gradually being replaced by electronic steering column locks. To use the electronic steering column lock to realize the anti-theft function of the vehicle, it is the key to adopt a set of safe and reliable control methods. [0003] At present, most common electronic steering column lock control methods on the market control the electronic steering column lock E...
