Summary: | An apparatus and method for estimating pitch of a vehicle relative to a road. The apparatus includes: a wheel speed sensor unit that acquires wheel speed data; an inertial measurement unit (IMU) sensor section that acquires IMU data; a preprocessing unit that extracts a stop section and a movement section on the basis of the wheel speed data and the IMU data; and a gradient estimation section that estimates a vehicle pitch in a stop section and a road gradient in a movement section, and estimates a pitch of the vehicle with respect to the road based on the vehicle pitch and the road gradient.
一种用于估算车辆相对于道路的俯仰的装置和方法。所述装置包括:车轮速度传感器部,其获取车轮速度数据;惯性测量单元(IMU)传感器部,其获取IMU数据;预处理部,其基于车轮速度数据和IMU数据来提取停止区段和移动区段;以及坡度估算部,其估算在停止区段的车辆俯仰和在移动区段的道路坡度,并基于所述车辆俯仰和所述道路坡度来估算车辆相对于道路的俯仰。 |
