The invention discloses an automobile chassis domain control sensor architecture and dynamic state fusion calculation method, which comprises a chassis, wherein the chassis is provided with a suspension, a wheel speed sensor, a vertical acceleration sensor and a suspension displacement sensor, wheels arranged on the suspension, the wheel speed sensor, the vertical acceleration sensor and the suspension displacement sensor form a set of wheel assembly, and four sets of wheel assemblies are arranged on the chassis, namely, a left front wheel assembly, a left rear wheel assembly, a right front wheel assembly and a right rear wheel assembly. According to the invention, the wheel speed sensor, the vertical acceleration sensor, the suspension displacement sensor and the like are arranged for obtaining rotating speed parameters and vertical bounce acceleration parameters of the wheels, relative position change parameters of the wheels relative to chassis position change and the like. According to the invention, the running state of the wheels can be comprehensively acquired through the sensors, so that more comprehensive control parameters are provided for automatic control of the vehicle, and the calculation precision of the automobile dynamic state is greatly improved.

    一种汽车底盘域控传感器架构与动力学状态融合计算方法,包括底盘,在底盘上安装有悬架、轮速传感器、垂向加速度传感器、悬架位移传感器。悬架上安装的车轮以及轮速传感器、垂向加速度传感器以及悬架位移传感器构成一套车轮总成,在底盘上设置有四套车轮总成,分别为左前轮车轮总成、左后轮车轮总成、右前轮车轮总成以及右后轮车轮总成。本发明设置了轮速传感器、垂向加速度传感器、悬架位移传感器等,用于获取车轮的转速参数、垂向跳动加速度参数以及车轮相对于底盘位置变化的相对位置变化参数等,本发明通过上述传感器,能够全面的获取车轮的运行状态,从而为车辆的自动化控制提供更加全面的控制参数,极大程度地提高了汽车动力学状态计算精度。
