VEHICLE PROPORTIONAL VALVE PRESSURE CONTROLLER BASED ON CAN BUS, AND COMMUNICATION METHOD

摘要

Disclosed are a vehicle proportional valve pressure controller based on a CAN bus, and a communication method, wherein a CAN module is provided on the vehicle proportional valve pressure controller, and the CAN module is connected to the CAN bus, and can be connected to a vehicle ECU through the CAN bus. Thus, by means of defining a CAN bus packet protocol of a proportional valve controller, communication with the vehicle ECU is carried out through the CAN bus based on the packet protocol. For communication technology between the vehicle proportional valve pressure controller and the vehicle ECU, in the communication method, the CAN bus is used to replace a PWM interface, thus the existing problem of current vehicle proportional valve pressure controllers based on a PWM communication mode is effectively overcome, and valuable PWM resources of the vehicle ECU can be further released.
