A realization method of vehicle communication system based on Formula Student racing car

Abstract

The invention discloses a realization method of a full car communication system based on a formula student race car. The method comprises following steps of determining data needing to be collected for an all-electric race car of this time; determining modules using CAN bus communication according to demands; setting CAN bus priories, wherein a protocol identity ID is set for each module; setting a CAN bus protocol, wherein the bus protocol is set according to using demands; developing and designing CAN communication programs; and testing and analyzing the CAN bus communication.

Description

technical field [0001] The invention relates to a method for whole-vehicle communication of an electric formula racing car for college students. Background technique [0002] Formula SAE (FSAE) is a comprehensive engineering education event for college students. It was launched by the International Society of Automotive Engineers (SAE International) in 1978 and has events in 15 countries around the world. Before the race, the team usually spends 8 to 12 months designing, building, testing and preparing the racing car. It is expected to make a racing car with low manufacturing cost, easy maintenance, good reliability, beauty and comfort, and common parts. Now it has become a world-wide engineering design competition for college students with global influence, known as "the F1 of academia". [0003] Formula Student China (FSC): [0004] China introduced this international event in 2010, and domestic universities and people in related industries actively participated in it. ...

AI Technical Summary

Problems solved by technology

[0006] General vehicle communication methods are used in commercial vehicle production, and we require independent design and construction of a dual-motor rear-wheel drive racing car, so the general vehicle communication technology is not suitable for racing car design Above, there are two reasons: one is that the communication technology of the whole vehicle is produced by a professional manufacturer, and it is difficult to buy it directly from the manufacturer, and the manufacturer is unwilling to design a communication solution for electric racing cars; The communication technology and solutions used in the field are very complicated, and contain many functions that are not needed in electric racing cars, and if they are bought directly from the manufacturer, they cannot be directly applied, but have to be modified, but the modification is very difficult. Large, the manufacturer develops and researches in one piece, and the modification is almost equivalent to a new design, so it is not suitable for electric racing cars
