Four-wheel antiskid system for undergraduate formula racing car

Abstract

The invention discloses a four-wheel antiskid system for an undergraduate formula racing car. The four-wheel antiskid system comprises an electronic control unit including a data recorder, four Hall wheel speed sensors used for collecting the rotate speed of four wheels of the racing car in real time and a throttle position sensor used for collecting the throttle position in real time; the output ends of the four Hall wheel speed sensors and the throttle position sensor are connected to the electronic control unit, and the output end of the electronic control unit is connected to an oil injection mechanism and an ignition mechanism of an engine of the racing car. When the electronic control unit detects that the slip rate of the racing car is too large, the ignition mechanism and the oil injection mechanism of the engine can be directly controlled to reduce the output torque of the engine, so that the slip rate when the racing car drives is reduced; an engine operating mechanism is used directly for solving the antiskid problem, the whole system is simpler and more convenient to use, and the system is stale and reliable.

Description

technical field [0001] The invention relates to the technical field of student formula racing cars, in particular to a four-wheel anti-skid system for student formula racing cars. Background technique [0002] The China Student Formula Car Competition follows the rules of international competitions. The participating teams must design and manufacture a small single-seater formula car with excellent performance in acceleration, braking, and handling within one year, and participate in 8 static and dynamic competitions. , specifically: marketing reports, race car design, manufacturing cost analysis, linear acceleration, figure-eight winding, high-speed obstacle avoidance, durability testing, and fuel economy. In order to ensure that the racing car can still run at high speed and stably during ejection start and high-speed obstacle avoidance, it is generally achieved by controlling the wheel slip rate by braking in the prior art, which requires the addition of a complex anti-lo...

Problems solved by technology

In order to ensure that the racing car can still run at high speed and stably during ejection start and high-speed obstacle avoidance, it is generally achieved by controlling the wheel slip rate by braking in the prior art, which requires the addition of a complex anti-lock brake system for automobiles ABS (Anti-lock Braking System) or ASR (Anti-Slip Regulation), etc., not only increase the cost but also affect the stability and reliability of the car
