Application: Tire position identification device and tire position identification method (Patent ID: US20230415524A1)
The patent filed by Alps Alpine Co Ltd. describes a tire position identification device that can determine the positions of wheels to which tires are attached based on factors like tire deformation, vehicle turn detection, and speed. The device uses processing circuitry to detect tire deformation, vehicle turns, and speed, allowing it to infer the wheel positions accurately. Additionally, the device can determine the side of the wheel (inner or outer) and the direction of the wheel (forward or backward) based on the vehicle's movement and load distribution on the tires.
Furthermore, the tire position identification device can rank tires based on revolution speed and load magnitude to determine which wheels they are attached to, whether front or rear, and on which side of the vehicle. The device is capable of identifying tire positions even in complex wheel arrangements, such as vehicles with multiple rows of wheels. By utilizing deformation data from continuously rotating tires, the device can also detect tire wear. Overall, the tire position identification device offers a comprehensive method for accurately determining the positions of wheels based on various vehicle and tire parameters, enhancing safety and efficiency in automotive applications.
