The invention relates to a system and method for managing stall torque limits. A system for managing motor torque in a vehicle determines a loss of speed amount corresponding to a motor speed and determines a torque limit based on the loss of speed amount. The system determines a desired torque value, and determines whether to generate modifications to one or more baseline torque commands based on the desired torque value and the torque limit. If the baseline torque command is not modified, the system generates the one or more baseline torque commands corresponding to one or more motors. If the baseline torque is modified, the system generates one or more modified torque commands corresponding to the one or more motors based on the modification and based on the one or more baseline torque commands. The modified torque command may include a minimum value less than the torque limit and a maximum value corresponding to a wheel slip torque.

    本公开涉及用于管理失速扭矩极限的系统和方法。一种用于管理车辆中的马达扭矩的系统确定对应于马达速度的失速度量并基于该失速度量确定扭矩极限。该系统确定期望的扭矩值,并且基于该期望的扭矩值和该扭矩极限确定是否生成对一个或多个基线扭矩命令的修改。如果不修改该基线扭矩命令,则该系统生成对应于一个或多个马达的该一个或多个基线扭矩命令。如果修改该基线扭矩,则该系统基于该修改并基于该一个或多个基线扭矩命令生成对应于该一个或多个马达的一个或多个经修改的扭矩命令。该经修改的扭矩命令可包括小于该扭矩极限的最小值和对应于车轮打滑扭矩的最大值。
