FSAC racing car active braking system based on manned and unmanned driving modes

Abstract

The invention provides an FSAC racing car active braking system based on manned and unmanned driving modes. The FSAC racing car active braking system comprises a first active braking cylinder, a second active braking cylinder, a linear motor, a first passive braking cylinder, a second passive braking cylinder, a first two-position three-way electromagnetic valve, a second two-position three-way electromagnetic valve and an unmanned driving control system. Compared with an existing scheme of a servo motor and a mechanical transmission mechanism, the control circuit is adopted to accurately control the linear motor to move, and then the service braking function of an unmanned driving mode is achieved. The manned driving mode and the unmanned driving mode are independent from each other through switching of different driving modes, and the active mode and the passive mode are both of a double-loop design, so that safety is guaranteed. The innovation lies in that an MOSFET is applied, the size is dozens of times smaller than that of a relay, the switching frequency is high, the response speed is high, noise is avoided, energy consumption is low, physical contacts are avoided, and electromagnetic interference is avoided, so that the problems of limited space and light weight of an automobile are solved.

Description

technical field [0001] The invention relates to a braking system for racing cars, in particular to an active braking system for FSAC racing cars based on manned and unmanned driving modes applied to driverless formula racing cars. Background technique [0002] The Formula China College Student Driverless (FSAC) Racing Contest is an automobile design and manufacturing competition organized by students from colleges and universities majoring in automotive engineering or automotive related majors. According to the competition rules and racing car manufacturing standards, each participating team will design and manufacture a small single-seater car with excellent performance in autonomous driving system (AS), acceleration, braking, handling, etc. within one year. Recreational racing, a race that successfully completes all or part of an event segment. The China College Student Driverless Formula Competition is divided into static and dynamic competitions, and dynamic competition...

AI Technical Summary

Problems solved by technology

The existing solution is to use a small servo motor to pull (push) the original brake pedal through a mechanical reduction transmission mechanism. The structure of this kind of solution takes up a lot of space, and it is difficult to arrange it in the narrow space of the Formula Student racing car, which does not meet the lightweight design of the vehicle. concept, but also prone to mechanical interference, low control accuracy, prone to delays and potential safety hazards for drivers and vehicles
