The Toyota Research Institute (TRI) is advancing autonomous drifting technology with potential uses in high pressure driving scenarios. This effort focuses on enriching safety systems by enabling controlled, automatic drifting responses during critical moments.
The non-human version of the Supra was introduced in February, and the initial test video showcases its capability. The vehicle remains under driver control in normal operation, yet when confronted with an obstacle or a tight bend, the car can switch to autonomous mode and execute a drift to navigate the challenge more efficiently.
Supplying this system is a non-linear predictive control framework paired with a brake force distribution mechanism that can lock individual wheels as needed. The electronics oversee steering, throttle, and the sequential gearbox, allowing a computed trajectory to guide the car through the maneuver with precision. The integration of these controls creates a seamless handoff from human input to automated execution when necessary.
During drifting, the stabilization system and anti-lock braking system are temporarily disengaged. This intentional disablement enhances lateral freedom, letting the car slide sideways if required to maintain the intended path. The approach also proves advantageous on icy surfaces, where a quick managed skid can be corrected by the system to restore the desired course without sacrificing control.
Viewed broadly, autonomous drift technology emerges as a potential active safety feature. By anticipating hazards and providing a controlled response, the system can reduce risk in situations that challenge conventional reaction times. The ongoing work aims to translate these capabilities from test scenarios to real-world road use, where reliability and predictability are paramount.
