The invention discloses a method, a device and equipment for determining a side slip angle of a vehicle body. The method comprises the steps that motion state parameters of a vehicle at the first moment are obtained, the motion state parameters comprise the running speed, the transverse acceleration, the longitudinal acceleration and the yaw velocity of the vehicle, and the wheel force of the vehicle at the first moment is determined according to the final slip angle value of the vehicle at the second moment and the motion state parameters of the vehicle at the first moment, the second moment is a moment before a sampling step length of the first moment, the wheel force comprises a front axle transverse force, a rear axle transverse force, a front axle longitudinal force and a rear axle longitudinal force of the vehicle, and the final value of the slip angle of the vehicle at the first moment is determined according to the wheel force of the vehicle at the first moment. According to the embodiment of the invention, the accuracy of vehicle body slip angle measurement can be improved.

    本申请公开了一种车身侧偏角的确定方法、装置及设备。该方法包括:获取车辆在第一时刻的运动状态参数,其中,运动状态参数包括车辆的行驶速度、横向加速度、纵向加速度以及横摆角速度,根据车辆在第二时刻的侧偏角最终值和第一时刻的运动状态参数确定车辆在第一时刻的车轮力,其中,第二时刻为第一时刻一个采样步长之前的时刻,车轮力包括车辆的前轴横向力、后轴横向力、前轴纵向力和后轴纵向力,根据车辆在第一时刻的车轮力确定车辆在第一时刻的侧偏角最终值。根据本申请实施例,能够提升车身侧偏角测量的准确性。
