Development of Traction Control Systems for Formula One

Article of Honda R&D Technical Review F1 Special (The third Era Activities)

Summary

Efforts have been made toward the development of traction control that controls the amount of tire slip at a level that exceeds the abilities of Formula One drivers and enhances turning acceleration performance, and the development of overrun control that is intended to prevent rear tire lockup by using engine torque when the brakes are being applied. Numerous control systems have been applied in racing based on modern control theories, including high-precision engine speed control and wheel speed feedback control, which is extremely challenging in Formula One, where driving at the limit is the norm.
Launch control, which is control applied in the start of a race, has also realized complete direct control of clutch transfer torque. Development has proceeded on start assist systems that can enhance start performance with reliable repeatability while continuing to satisfy regulations even after prohibition of automatic clutch control. The direct push clutch and other new technologies have been actively adopted.
