The invention discloses a full-function diagnosis commercial vehicle body controller which comprises a switch control portion, a MCU (microprogrammed control unit) portion, a SPI detection portion, a driving module portion, a CAN (controller area network) communication portion and a power source portion. The SPI detection portion is connected with the MCU portion which is further connected with a remote-control receiving portion, a driving portion, the switch control portion and the CAN communication portion. Small signal control, power control, diagnosis, power supply and CAN communication are designed to be all completed in a control box. Circuits are designed to perform SPI detection on power output, a MCU monitors working condition of each circuit in real time, instrument display of an instrument desk is realized by means of CAN communication, in other words, either open-circuit shortout or abnormal working of the circuits can be presented on instruments to inform a user of current condition, so that more humanized driving is realized, and vehicle safety and comfort are improved.
Description
technical field [0001] The invention relates to a vehicle body controller, in particular to a full-function diagnostic commercial vehicle body controller. Background technique [0002] Cars are already an indispensable means of transportation in our daily work. With the continuous advancement of science and technology, people have higher and higher requirements for the comfort and safety performance of cars. Nowadays, the body controller is an indispensable electrical product in the development of automotive electronics. Its main function is to integrate the control of various electrical appliances in the body, the working status of the car, and the anti-theft of the body, etc., and concentrate the core components of the electrical control part of the body. [0003] Body control technology is widely used in passenger cars, but commercial vehicle body control systems have only begun to emerge in recent years, basically using relays as power control methods, and have no diagno...
