AI Technical Summary
Technical Problem
Existing vehicle control systems struggle to accurately determine when wheels come into contact with bumps, particularly at low speeds, leading to delayed brake force application and potential wheel ride-over issues.
Method used
A control device that calculates the trajectory angle between the wheel's rotation center axis and the road surface using drive force and acceleration, allowing precise estimation of bump height and timely adjustment of brake/drive force to prevent wheel ride-over.
Benefits of technology
Enables quick and accurate control of vehicle motion over bumps by determining the trajectory angle, reducing the likelihood of wheel ride-over and ensuring safe vehicle operation even at low speeds.
