Claim One:
1. A method of operating an electric vehicle by controlling an operating speed and/or a torque of an electric motor of the electric vehicle in accordance with an operational model, the method being implemented by a processor configured to execute machine-readable instructions, the method comprising: storing the operational model in a storage device, the operational model comprising a plurality of operation positions of the electric vehicle, an optimal region of the electric motor, a given operation position corresponding to a speed parameter, a torque parameter and an operation efficiency parameter of the electric motor; receiving a value for a current speed parameter and a value for a current torque parameter from a sensor device; determining a current operation position of the electric motor in the operational model based on the value for the current speed parameter and the value for the current torque parameter; receiving, from a driving input system, a target speed parameter and a target torque parameter corresponding to a target operation position of the electric motor in the operational model; determining whether the current operation position is located in the optimal operation region; and in response to the current operation position being determined not located in the optimal operation region: adjusting at least one of the current speed parameter and the current torque parameter to move, along a first path, the current operation position to an intermediate operation position, the intermediate operation position corresponding to a value for an intermediate speed parameter and value for an intermediate torque parameter, and being located in the optimal operation region; and adjusting at least one of the intermediate speed parameter and the intermediate torque parameter to move, along a second path, the intermediate operation position to the target operation position.
