Title:
ELECTRIC VEHICLE DRIVE CONTROL METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/135180
Kind Code:
A1
Abstract:
An electric vehicle drive control method comprises: acquiring accelerator pedal position information of an electric vehicle (S11); determining, on the basis of a pre-configured steady speed versus accelerator pedal position reference table, target motor drive power corresponding to the acquired accelerator pedal position information (S12), wherein the steady speed versus accelerator pedal position reference table stores relationships between multiple pieces of accelerator pedal position information and corresponding motor drive power, and each motor drive power value corresponds to a different steady speed of the electric vehicle; and driving an electric motor of the electric vehicle on the basis of the target motor drive power, such that the electric vehicle travels at a constant speed according to a target steady speed corresponding to the target motor drive power (S13). The present application further relates to an electric vehicle drive control system. The method avoids heavy operation burden and difficulties caused by frequently operating an accelerator pedal, enables the electric vehicle to travel at different steady speeds according to different accelerator pedal position information, and improves the driving experience of users.
