Electronic throttle control system for formula student racecar

Abstract

The invention relates to an electronic throttle control system for a formula student racecar. The electronic throttle control system for the formula student racecar comprises a controller. The first signal input end of the controller is connected with the signal output end of an accelerator pedal module, the second signal input end of the controller is connected with the output end of a braking oil pressure sensor, the third signal input end of the controller is connected with the signal output end of a fault detection unit, the signal output end of the controller is connected with the signal input end of an electronic throttle body through a motor driving circuit, and the electronic throttle body outputs feedback signals to the fourth signal input end of the controller. The electronic throttle control system for the formula student racecar is simple in structure and high in reliability, has the functions of throttle position sensor fault detection, pedal position sensor fault detection and braking failure protection and preventing dangerous behaviors caused by misoperation of a racecar driver, can achieve accurate control in the control process, and guarantees the steering stability and the driving safety of the racecar.

Description

technical field [0001] The invention relates to the technical field of the air intake system of the student formula racing car engine, in particular to an electronic throttle control system for the student formula racing car. Background technique [0002] Formula Student (FSAE) is a comprehensive engineering education event for college students. Since its inception in 1978, it has been more than 30 years, and the events have covered 24 countries around the world. The event is generally organized by the Society of Automotive Engineers of various countries, with college students forming a team to participate. The team is required to follow common standards and rules, and design and manufacture a small single-person car by itself, similar to the simplified version of Formula One. It is required that the racing car has a high level of acceleration, braking and handling, and is stable and durable enough. The participating vehicles have to undergo a series of test items, includin...

AI Technical Summary

Problems solved by technology

[0003] At present, the vast majority of domestic formula racing cars use mechanical pull-wire throttles. Since the traditional mechanical pull-wire throttles are completely controlled by the driver's subjective control of the throttle opening, they can no longer meet the safety, power, and handling stability of racing cars. and fuel economy requirements
