Description

technical field [0001] The invention relates to the field of remote control, in particular to a remote control device and a control method for a new energy vehicle. Background technique [0002] In new energy vehicles, since the vehicle system is composed of multiple electronic control units, each electronic control unit uses a controller area network (Controller Area Network, CAN) to form a communication connection network. The core of the control unit, each electronic control unit must exchange data with the vehicle controller. After the data is processed by the vehicle controller, it is sent to the vehicle network through CAN communication. At present, the remote communication method of the vehicle controller is to add an independent electronic control unit of the 4G module on the bus, connect to the CAN bus network, process the information obtained by the CAN bus through the 4G module, and connect to the remote node wirelessly . Since the 4G module is connected to CAN ...

Problems solved by technology

Since the 4G module is connected to CAN communication, the communication baud rate of the commercial vehicle CAN bus is 250K BPS, and the CAN bus has a limit on the bus load rate, which cannot meet the transmission of large data such as pictures; and the above-mentioned remote communication method requires an independent 4G electronic control unit, The 4G electronic control unit communicates with the vehicle controller through the CAN bus

Independent 4G electronic control unit requires independent power supply and structure, including independent CAN communication interface circuit and microprocessor, thus wasting product cost
