Abstract

The invention discloses a four-wheel anti-skid system for a college student formula racing car, which includes an electronic control unit including a data recorder, four Hall wheel speed sensors for real-time acquisition of the four wheel speeds of the racing car, and a sensor for real-time acquisition of the throttle position. The throttle position sensor, the output ends of the four Hall wheel speed sensors and the throttle position sensor are respectively connected to the electronic control unit, and the output ends of the electronic control unit are respectively connected to the fuel injection mechanism and the ignition mechanism of the racing engine. In the present invention, when the electronic control unit detects that the slip rate of the racing car is relatively large, the output torque of the engine is reduced by directly controlling the ignition mechanism and the fuel injection mechanism of the engine, thereby reducing the slip rate when the racing car is driven, which directly utilizes the engine itself The working mechanism solves the problem of anti-skid, and the whole system is more concise, convenient, stable and reliable.

Description

Technical field

[0001] The invention relates to the technical field of the Formula Student racing car, in particular to a four-wheel anti-skid system of the Formula Student racing car. Background technique

[0002] In accordance with the rules of international competitions, the Chinese Formula Student Race shall design and manufacture a small single-seater formula car with excellent performance in acceleration, braking, handling and other aspects within one year, and participate in 8 static and dynamic events. , Specifically: marketing report, racing car design, manufacturing cost analysis, straight-line acceleration, figure eight winding pile, high-speed obstacle avoidance, durability test and fuel economy. In order to ensure that the car can still drive at high speed and stably during ejection start and high-speed obstacle avoidance, the prior art generally uses braking to control wheel slip to achieve this, which requires the addition of a complex anti-lock braking system for ...
