Development of the Traction Control System with the Custom Electrical Control Unit for the Formula SAE Car 2007-32-0119
The Traction Control Systems (TCS) for the FSAE car were developed with the Fuel/Ignition Cut (FIC) method and the Ignition Retard (IR) method. A slip speed was used for the TCSs and a custom Engine Control Unit (KF-ECU07) was developed with commercial devices. With the FIC TCS, the engine was stalled and the IR TCS worked better. KF-ECU07 was 7.6% of the commercial high-quality ECU in price and contributed to the cost event point gain in FSAE. The driver load was evaluated with the duration ratio of the partial throttle aperture. The duration ratio of the partial throttle aperture was 52% with the IR-TCS compared with 64% without IR-TCS and 19% driver load was decreased.
