Design and optimization of low voltage intelligent control circuit for FSEC formula racing cars

Abstract

According to the regulations of Formula Student Electric China (FSEC), this paper has built a modular integration low-voltage control system to solve problems such as large volumes, poor maintenance, high disassembly difficulty in existing low-voltage control circuit systems. Through improvements to enhance circuit integration, maintainability, and reduce failure rates in this design. The operating rules for the brake system plausibility device (BSPD), traction system active light (TSAL) and key failure lock circuit failures are examined. Circuit simulation and field tests show that the proposed system can achieve up to a 30% reduction in Volume and a 60% decrease in failures relative to traditional systems; It has improved vehicle Stability and Reliability.
