A system for managing motor torque in a vehicle determines a stall metric corresponding to motor speed and determines a torque limit based on the stall metric. The system determines a desired torque value, and determines whether to generate a modification to one or more baseline torque commands based on the desired torque value and the torque limit. If the baseline torque command is not to be modified, the system generates the one or more baseline torque commands corresponding to one or more motors. If the baseline torque is to be modified, the system generates one or more modified torque commands corresponding to the one or more motors based on the modification and on the one or more baseline torque commands. The modified torque command may include a minimum value that is less than the torque limit and a maximum value that corresponds to a wheel slip torque.
