Abstract:
Systems and methods for controlling the operating speed and the torque of an electric motor using an operational model are described. An operational model for the electric motor, including a plot of engine performance parameters, is used for reference, and a most efficient output path, which may pass through an optimal operation region in the operational model, is selected. The most efficient output path may be determined, for example, according to locations of a current output state and a to-be-reached target state in the operational model, enabling the operating state of the motor to reach the target state from the current operating state. By selecting a more efficient output path, the operating efficiency of the motor may be optimized, the life of a battery improved and/or the operating mileage of the vehicle may be increased, without significantly reducing the driving experience.

Claim (Index 1):
An electric vehicle motor controller, comprising:\n a central processing unit (CPU); and a storage device including an operational model stored thereon, the operational model including a plurality of operation positions and an optimal operation region of an electric motor, each operation position corresponding to a speed parameter, a torque parameter and an operating efficiency parameter of the electric motor; wherein the CPU is configured to:\n receive an input indicating a detected current speed parameter and a current torque parameter of the electric motor; \n determine a current operation position of the electric motor in the operational model based on the current speed parameter and the current torque parameter; \n determine two transition paths based on the current operation position, and the operational model, the two transition paths including a first path consisting of one vector, and a second path consisting of two vectors; \n select one of the two transition paths for controlling the electric motor; \n control the electric motor using the selected transition path; and \n amend an efficiency parameter on a selected position in the operational model according to a calculated efficiency parameter on the target operation position.
