Integrated multifunctional control system applied to electric formula car

Abstract

The invention discloses an integrated multifunctional control system applied to an electric formula car. The integrated multifunctional control system comprises a whole car control module, a data acquisition module and a power distribution module, the data acquisition module, the whole vehicle control module and the power distribution module are all arranged on the PCB, the PCB adopts a four-layer circuit board design, the middle two layers are arranged to be a power supply layer and a ground layer respectively, and the backflow area of a power supply is reduced; equilong wiring is carried out on high-speed crystal oscillator wires, and the high-speed crystal oscillator wires are close to chip pins as much as possible; the filter capacitor is close to a chip pin as much as possible, so that effective filtering processing on a power supply input into the chip is ensured. According to the invention, a part of logic circuits of the power distribution module are integrated into the PCB of the control system, so that the number of wires of the power distribution box is reduced, the problems of disordered internal wire harnesses, dense welding spots and unreasonable layout are solved, errors of manual wiring and assembly are reduced, and thus the stability and safety of the circuits are improved.

Description

technical field [0001] The invention belongs to the field of electric vehicle control systems, in particular to an integrated multifunctional control system applied to electric formula racing cars. Background technique [0002] The vehicle control system is the core content of vehicle control. The performance of the vehicle control system directly affects the development cycle and stability of the vehicle, and is the core technology of Formula E racing. At present, the research and development of the vehicle control system in my country mainly faces the development of electric new energy vehicles. The control requirements and control modes are quite different from the competition, the interface definitions are different, and after-sales maintenance is a big problem. The vehicle controller currently used in the prior art has a single control mode, lacks data collection, is difficult to debug, and has frequent failures related to vehicle wiring, poor vehicle stability, and hig...
