A vehicle motion management (VMM) system for a heavy vehicle configured to: obtain a desired wheel force value for at least one wheel of the vehicle; -determining a torque limit of a first motion support device (MSD) associated with the at least one wheel based on the desired wheel force value; -determining a tire model based on a relationship between the wheel force and the wheel speed of the at least one wheel; -determining a desired wheel speed of the first MSD based on the tire model; and-determining a torque fill request for a second MSD of the heavy vehicle based on the desired wheel force and based on a torque capability of the first MSD, where the VMM system is further configured to:-determining a torque fill request for the second MSD in accordance with a torque limit of the first MSD if an operating torque of the first MSD is limited by the torque limit, and determine a torque fill request for the second MSD based on an applied torque status signal received from the first MSD if the operating torque of the first MSD is not limited by the torque limit.
一种用于重型车辆的车辆运动管理(VMM)系统,其被配置为:‑获得车辆的至少一个车轮的期望车轮力值;‑基于期望车轮力值来确定与至少一个车轮相关联的第一运动支持装置(MSD)的扭矩极限;‑基于至少一个车轮的车轮力与车轮速度之间的关系来确定轮胎模型;‑基于轮胎模型来确定第一MSD的期望车轮速度;以及,‑基于期望车轮力并基于第一MSD的扭矩能力来确定对重型车辆的第二MSD的扭矩填充请求,其中VMM系统还被配置为:‑在第一MSD的操作扭矩受到扭矩极限的限制的情况下根据第一MSD的扭矩极限来确定对第二MSD的扭矩填充请求,并在第一MSD的操作扭矩未受到扭矩极限的限制的情况下根据从第一MSD接收的施加扭矩状态信号来确定对第二MSD的扭矩填充请求。
