FSAE pneumatic gearshift device with data recording function and FSAE pneumatic gearshift method with data recording function

Abstract

The invention provides an FSAE pneumatic gearshift device with a data recording function and an FSAE pneumatic gearshift method with the data recording function. The FSAE pneumatic gearshift device with the data recording function comprises a gearshift mechanism, a gearshift control and data recording unit and a steering wheel. The gearshift mechanism is placed in a vehicle engine, and comprises an air cylinder support, a double-acting air cylinder and a gearshift rocker arm; a display screen is arranged in the center of the steering wheel; the gearshift control and data recording unit is arranged in the steering wheel; the steering wheel is provided with a paddle lifting mechanism; the gearshift control and data recording unit is connected with a magnetic exchange valve and the paddle lifting mechanism; and the gearshift control and data recording unit is connected with a vehicle ECU (Electronic Control Unit) through a CAN (Controller Area Network) bus. The FSAE pneumatic gearshift device with the data recording function provided by the invention can realize simple, convenient, fast and stable gearshift, can record several data transferred from the ECU, can be externally connected with various sensors to acquire data, and realizes accurate analysis and optimization on racing car control.

Description

technical field [0001] The invention relates to the field of gear shifting of racing cars and automobiles, in particular to an FSAE pneumatic gear shifting device and method with a data recording function. Background technique [0002] FSAE is a college student formula racing competition organized by the national associations of automotive engineers for undergraduates and postgraduates who are studying or graduating within 7 months. Students participating in the competition must use their spare time to independently design and manufacture a formula car within one year. Gear shifting is an important part of racing car control, and the speed and stability of gear shifting greatly affect the driving performance of the car. [0003] Most of the engines used in this competition are sequential motorcycle engines, which do not have the function of automatic shifting. They adopt mechanical shifting, and the shifting method is very different from that of ordinary cars. They must be ...

AI Technical Summary

Problems solved by technology

Since most racing cars do not have a display system, the driver does not know enough about the running status of the car, especially for the current gear, it is judged entirely by driving experience and it is easy to make mistakes, causing serious troubles to the driver

Most racing cars of the teams do not have a driving recorder, and the driving recorder on the market is expensive and has a single function, which is difficult to meet the requirements of the racing car

The existing motor gear shifting mechanism is too complicated, consumes a lot of power, and is difficult to control when returning to normal, and there will always be small errors, resulting in faster structural wear and easy to get stuck

Other pneumatic shifting mechanisms use carbon dioxide as the power gas, which is easy to corrode gas cylinders and other accessories, and there are too many solenoid valves, gas transmission lines, cylinders, etc., and the structure is complex and easy to leak

With mechanical shifting, the driver has to let go of the steering wheel to change gears when turning, which will have a huge impact on the speed of the driver when cornering and the control of the car.
