Systems and methods for managing stall torque limits

A method for managing motor torque in a vehicle, the method comprising:

• identifying, for each of one or more motors, an operating range based on a rotational motor speed and based on a desired torque value;
• retrieving a reference operating range from memory, wherein the reference operating range is based on a thermal characteristic of the one or more motors;
• determining a torque command mode based on the operating range and the reference operating range;
• applying a first torque command mode if the operating range is within the reference operating range;
• and
• applying a second torque command mode if the operating range is not within the reference operating range, wherein the second torque command comprises a baseline command and a modulation, and wherein the second modified torque command corresponds to an effective torque value greater than the reference operating range.

A system comprising:

• a sensor configured to sense motor speed of one or more motors;
• and
• control circuitry coupled to the sensor and configured to:
• determine a stall torque limit based on the motor speed and a thermal characteristic of the one or more motors;
• determine one or more baseline torque commands corresponding to a desired torque value;
• if the desired torque value is less than the stall torque limit, generate the one or more baseline torque commands corresponding to the one or more motors;
• and
• if the desired torque value is greater than the stall torque limit, generate one or more modified torque commands corresponding to the one or more motors based on a modification to the one or more baseline torque commands, wherein each of the one or more modified torque commands corresponds to an effective torque value greater than the stall torque limit.
