Method, device and system for controlling new energy vehicle body load

Abstract

The embodiment of the invention discloses a method, device and system for controlling new energy vehicle body load. The method comprises the steps of sending a bus load state detection message to a controller area network (CAN) body bus controller; receiving a CAN bus state code replied based on the bus load state detection message, from the CAN body bus controller; packaging a remote control instruction received through a remote monitoring module into a CAN signal when it is determined that a CAN body bus is in a normal state based on the CAN bus state code, and sending the CAN signal to a body control module through the CAN body bus; and converting the remote control instruction received through the remote monitoring module into a switching value signal when it is determined that the CANbody bus is in a busy state based on the CAN bus state code, and sending the switching value signal to the body control module through a hard wire, wherein the remote control instruction is used forcontrolling the body load. The transmission load of the vehicle CAN bus is reduced, the load control response speed is improved, and the information security of a vehicle intranet is also improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automobiles, in particular to a method, device and system for controlling body loads of new energy vehicles. Background technique [0002] Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. As a new energy vehicle with reduced oil consumption, low pollution, and low noise, electric vehicles are considered to be an important way to solve the energy crisis and environmental degradation. [0003] The vehicle-mounted remote monitoring system can realize functions such as wireless remote monitoring, GPS map positioning, historical vehicle trajectory playback, voice intercom, alarm linkage, remote video storage, remote download video, vehicle area mana...

AI Technical Summary

Problems solved by technology

[0005] With the provision of automobile intelligence, the transmission information on the CAN network bus in the vehicle not only includes communication information between various subsystems, but also includes more and more network information outside the vehicle, which not only causes the transmission burden of the CAN bus of the vehicle body, but also It will also bring great security challenges to vehicle information security.
