The invention relates to a vehicle body attitude control system. The vehicle body attitude control system comprises a gyroscope sensor used for obtaining a first motion signal, and the first motion signal comprises acceleration and angular velocity signals of a vehicle body in the X/Y/Z axis direction; the wheel end acceleration sensor is used for acquiring a second motion signal, and the second motion signal comprises an acceleration signal of a wheel; the multiple damping shock absorbers are used for controlling the posture of the vehicle body; the system controller ECU comprises an attitude calculation module, a suspension state calculation module and a suspension master control algorithm module, and the attitude calculation module obtains vehicle body motion state information and vehicle body point motion state information according to the first motion signal; the suspension state calculation module obtains suspension motion state information according to the second motion signal and the vehicle body point motion state information, the suspension master control algorithm module obtains an expected current value according to the vehicle body motion state information and the suspension motion state information, and the system controller ECU controls the multiple damping shock absorbers to act according to the expected current value. The invention provides a vehicle body attitude control system which is low in cost and can better execute vehicle body attitude control.

    本发明涉及一种车身姿态控制系统。该车身姿态控制系统包括陀螺仪传感器,用于获取第一运动信号,第一运动信号包括车身在X/Y/Z轴方向上的加速度和角速度信号;轮端加速度传感器,用于获取第二运动信号,第二运动信号包括车轮的加速度信号;多个阻尼减振器,用于控制车身姿态;系统控制器ECU,包括姿态解算模块、悬架状态计算模块和悬架主控算法模块,姿态解算模块根据第一运动信号获得车身运动状态信息和车身点运动状态信息,悬架状态计算模块根据第二运动信号和车身点运动状态信息以获得悬架运动状态信息,悬架主控算法模块根据车身运动状态信息和悬架运动状态信息获得期望电流值,系统控制器ECU通过期望电流值控制多个阻尼减振器动作。本发明提出了一种车身姿态控制系统,成本低且能更好地执行车身姿态控制。
