A vehicle motion management, VMM, system (360) for a heavy vehicle (100), the system comprising: at least one wheel speed sensor (106) configured to output a wheel speed signal indicative of a rotational speed of a respective wheel (102) on the vehicle (100); at least one inertial measurement unit (IMU) (110) configured to output an IMU signal indicative of an acceleration of the vehicle (100); a motion estimation function configured to estimate a vehicle motion state (s), including a vehicle-to-ground speed, based at least in part on the wheel speed signal and at least in part on the IMU signal; and a motion support device (MSD) coordination function configured to coordinate actuation of a plurality of MSDs of the heavy vehicle in accordance with a vehicle motion request and the vehicle motion state (s), where the motion estimation function is arranged to model errors in an estimated vehicle motion state (s), and outputting a free roll request to an MSD coordination function if the error of the modeling fails to meet acceptance criteria, wherein the MSD coordination function is arranged to reduce a wheel slip setpoint for one or more wheels (102) of the heavy vehicle (100) in response to receiving the free roll request from the motion estimation function.

    一种用于重型车辆(100)的车辆运动管理VMM系统(360),所述系统包括:至少一个车轮速度传感器(106),其被配置为输出指示所述车辆(100)上的相应车轮(102)的转速的车轮速度信号;至少一个惯性测量单元IMU(110),其被配置为输出指示所述车辆(100)的加速度的IMU信号;运动估计功能,其被配置为至少部分地基于所述车轮速度信号以及至少部分地基于所述IMU信号来估计包括车辆对地速度在内的车辆运动状态(s);以及运动支持装置MSD协调功能,其被配置为根据车辆运动请求和所述车辆运动状态(s)来协调所述重型车辆的多个MSD的致动,其中运动估计功能被布置为对估计的车辆运动状态(s)中的误差进行建模,并且在建模的误差未能满足接受标准的情况下向MSD协调功能输出自由滚动请求,其中MSD协调功能被布置为响应于从运动估计功能接收到自由滚动请求而减小重型车辆(100)的一个或多个车轮(102)的车轮滑移设定点。
