Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0013] Such as figure 1 As shown, both the mechanical door status switch and the door status switch are connected to the body controller. When the state of the car satisfies that the mechanical door lock is unlocked or at least one of the doors is not closed, the body controller receives a low-level signal. When the mechanical door is locked and all the doors are closed, the body controller receives a low-level signal. di...

Abstract

The invention relates to the field of cars, and in particular relates to a method for controlling error-locking of a mechanical door lock with a car key inside. The method comprises the steps of sending a mechanical door locking signal to a car body controller through a mechanical door lock state switch when locking the mechanical door of the car; sending a car key state detection instruction to an IMMO (Immobiliser) coil at the car through the car body controller while controlling to lock the mechanical door; feeding back the detection result to the car body controller through the IMMO coil; controlling whether the mechanical door is unlocked by the car body controller according to the state of the car key. With the adoption of the method, a user does not need to remove the key in case of going out for a short time, which facilitates the users without bags, and the key can be prevented from.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a control method for preventing a mechanical door lock from being mistakenly locked when the automobile key is not pulled out. Background technique [0002] Automotive electronic door lock control system is one of the most complex control systems in body electronics. The control of the door lock involves the user's personal and property safety. In the development of automobile models, it is often encountered that the mechanical door lock is locked abnormally, and the key is locked in the car, so that the user cannot open the door. This puts forward high requirements on the safety, stability and fault tolerance of the electronic door lock control system of the car. At present, the car door lock control industry is mainly controlled by the body controller. After all the doors are closed, the body controller receives the remote locking command, or the central control door lock command, ...
