Intelligent networked automobile serial data bus communication control system

Abstract

The invention discloses an intelligent networked automobile serial data bus communication control system. The intelligent networked automobile serial data bus communication control system comprises anew energy power serial data network segment EVCAN, a chassis serial data network segment PCAN, a vehicle body entertainment serial data network segment BCAN, a diagnostic serial data network segmentDiag CAN, a gateway GW and a vehicle-mounted T-BOX; the four serial data network segments of the EVCAN, the PCAN, the BCAN and the Diag CAN route signals and messages through the gateway GW. The intelligent networked automobile serial data bus communication control system has the advantages that the T-BOX is designed to be two CANs, and is used as a gateway to autonomously acquire required data and route signals of the EVCAN and BCAN, thereby reducing the communication delay and the CPU load rate of an original gateway; when the vehicle-mounted charging or remote starting are performed, the gateway does not need to be woken up, thereby reducing the power consumption of the whole vehicle; redundant backup can be performed on the original gateway through the T-BOX, and even in the case of gateway failure, the messages on the two gateways can also be routed through the T-BOX, thereby improving the robustness of the system.

Description

technical field [0001] The invention relates to a vehicle-mounted communication system, in particular to an intelligent network-connected vehicle serial data bus communication control system. Background technique [0002] Due to the requirements of the GB / T32960 national standard and the development trend of intelligent networked vehicles, ECUs continue to increase and become more complex, and the amount of communication data inside and outside the vehicle is increasing, which increases the communication load rate inside the vehicle and causes communication delays And the probability of communication errors increases. [0003] In the existing serial data bus control system, there are only body CAN and chassis power CAN, and the new energy powertrain is also integrated with the chassis power CAN. The new energy powertrain has great interference, which will affect the communication quality and reliability of the whole vehicle. sex. [0004] The Internet of Vehicles terminal ...

AI Technical Summary

Problems solved by technology

[0002] Due to the requirements of the GB / T32960 national standard and the development trend of intelligent networked vehicles, ECUs continue to increase and become more complex, and the amount of communication data inside and outside the vehicle is increasing, which increases the communication load rate inside the vehicle and causes communication delays and the probability of communication errors becomes larger

[0003] In the existing serial data bus control system, there are only body CAN and chassis power CAN, and the new energy powertrain is also integrated with the chassis power CAN. The interference of the new energy powertrain is relatively large, which will affect the communication quality and reliability of the whole vehicle. sex

[0004] The Internet of Vehicles terminal module is connected to the vehicle body CAN. Because the national standard requires the monitoring of the new energy data of the vehicle, the existing technical solutions must bridge the messages required by the TBOX to the BCAN through the gateway, which will increase the The network load rate of EVCAN and BCAN and the CPU load rate of the gateway
