Vehicle controller based on wire hardness judgment and identifying and controlling method thereof

Abstract

The invention discloses a vehicle controller based on wire harness judgment and an identifying and controlling method thereof. The controller comprises a digital quantity acquiring unit, an analog quantity acquiring unit, a power driver unit, a CAN (controller area network) communication interface unit and a microprocessor; after a vehicle is electrified and initialized, the controller realizes address identifying and executes a corresponding load control function. The controller and the identifying and controlling method thereof execute the control function of corresponding control areas through the information acquired by the digital quantity acquiring unit; the structure and the method could be used for realizing a uniform design of the controller, so that the structures of controllersapplied in the control areas of the vehicle can be totally the same; the address identification can be performed only through the wire harness setting educed by the controller, so that the purpose ofinstalling the same control unit in different positions to become the controller matched with the control areas of the vehicle can be achieved, therefore, the working load for designing the controller is reduced, the quantity of spare parts of the controller in maintenance process after the vehicle is assembled is reduced, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to automobile control technology, in particular to a vehicle controller based on wiring harness judgment and its identification control method. Background technique [0002] Existing vehicles include multiple parts that need to be controlled separately (for example: cockpit, power cabin, etc.), due to the needs of informatization, the electrical system of the vehicle uses multiple controllers to realize related functions. The functions are relatively independent. The usual design is to design hardware and software for each controller unit separately. Since the wiring harness of each part of the vehicle is different, the existing design is to design a special controller for each part to control, so that in the controller unit Some identical units also need to be designed repeatedly, increasing a lot of repeated work. [0003] Therefore, there is an urgent need for those skilled in the art to develop a vehicle controller and its i...
