Connection and control concepts for real-time mass estimation of an electric vehicle are provided. The vehicle comprises a vehicle control module (VCM). Further, the vehicle comprises an inverter coupled to the VCM, and an electric motor coupled to the inverter. The electric motor is configured to measure the torque output from one or more wheels of the vehicle. The VCM is configured to receive the torque output measured by the electric motor and estimate mass of the vehicle based on the received torque output.

Real-time mass estimation of electric vehicles

The present disclosure provides a method for torque management in a multi-motor electric vehicle. The method may include receiving a total torque request value from a vehicle control module (VCM), determining a first torque split value associated with a first motor and a second torque split value associated with a second motor, the sum of the first torque split value and the second torque split value being equal to the total torque request value, monitoring a thermal parameter of at least one of the first motor or the second motor, and adjusting the first torque split value and the second torque split value in response to the thermal parameter exceeding a threshold.
