Extended-range vehicle network topology device with slow charging function

Abstract

The invention provides an extended-range vehicle network topology device with a slow charging function. The device comprises a whole vehicle CAN bus, a power system CAN bus and a charging CAN bus, thewhole vehicle CAN bus and the power system CAN bus are connected to an OBD diagnosis port and are connected through a gateway of a whole vehicle controller, the whole vehicle CAN bus is connected with an anti-lock controller, an instrument, an air conditioner controller and a vehicle body controller, the power system CAN bus is connected with a driving motor controller, a DC / DC controller, an engine management system, a charger controller, a high-voltage battery controller and a vehicle-mounted charging controller, and the high-voltage battery controller is connected with the vehicle-mountedcharging controller through the charging CAN bus. According to the invention, except that the whole vehicle controller needs to have the capability of multiple network communication protocols, other controllers related to the power system only need to adopt one communication protocol, so that the network communication requirement of extended range can be realized on multiple whole vehicle platforms, and the development cost of the controllers related to the power system is reduced.

Description

technical field [0001] The invention relates to the field of driving control, in particular to an extended-range vehicle network topology device with slow charging. Background technique [0002] The range-extended vehicle can use a small-capacity high-voltage battery, and can make the engine work in a region with relatively high thermal efficiency for a long time. Some passenger cars and commercial vehicles on the market use the extended-range power system. In the existing system, passenger cars and commercial vehicles have their own network topology, the network communication protocol of passenger cars generally adopts ISO11898, and the network communication protocol of commercial vehicles generally adopts J1939, which requires the power system-related controllers Need to comply with a variety of communication protocols. Since each controller needs to comply with multiple communication protocols, the development cost and management cost of the controller will be greatly in...

AI Technical Summary

Problems solved by technology

Since each controller needs to conform to multiple communication protocols, the development cost and management cost of the controller will be greatly increased. Therefore, there is a lack of a network topology device that can reduce the development cost and management cost of the controller
