The invention relates to a vehicle sideslip angle estimation system and method. The vehicle sideslip estimation system includes: a sensor mounted on a vehicle; and a kinematic model that receives signals from the sensors to estimate a lateral speed of the vehicle. A compensated acceleration calculator calculates a compensated lateral acceleration as a measure of a condition resulting in a deviation from the measured lateral acceleration. A lateral acceleration calculator determines whether a lateral acceleration error is greater than a predefined threshold based on the compensated lateral acceleration and the measured lateral acceleration. The filter corrects an estimated lateral velocity of the vehicle when the lateral acceleration error is greater than a predefined threshold. When the lateral acceleration error is less than a predefined threshold, a speed output register registers an estimated lateral speed of the vehicle, and a sideslip calculator calculates a sideslip angle of the vehicle in real time according to the registered lateral speed of the vehicle and a longitudinal speed of the vehicle.

    本发明涉及车辆侧滑角估计系统和方法。具体公开了一种车辆侧滑估计系统包括:传感器,其安装在车辆上;以及运动学模型,其从传感器接收信号以估计车辆的侧向速度。补偿加速度计算器计算补偿的侧向加速度,作为导致偏离测量的侧向加速度的条件的量度。侧向加速度计算器基于补偿的侧向加速度和测量的侧向加速度来确定侧向加速度误差是否大于预定义阈值。当侧向加速度误差大于预定义阈值时,滤波器校正车辆的估计的侧向速度。当侧向加速度误差小于预定义阈值时,速度输出寄存器寄存车辆的估计的侧向速度,并且侧滑计算器根据车辆的寄存的侧向速度和车辆纵向速度来实时地计算车辆的侧滑角。
