Abstract

The invention discloses an electric automobile and a whole automobile controller and a whole automobile control method. The whole automobile control method comprises the steps that in a whole automobile driving mode, the throttle opening and speed of the electric automobile are acquired, a formula is substituted to calculate a motor torque to achieve fine management of torque output according to driving intention and driving condition. The formula is shown in the description, Throttle_Torq represents the motor torque; Speed represents automobile speed; Throttle_Map represents the throttle opening; fi(Speed) represents a function of motor torque about the represents automobile speed when the throttle opening reaches ki, i = 1 or 2, 0% <= k1 < k2 <= 100%.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control technology, and more specifically, relates to an electric vehicle, a vehicle controller and a vehicle control method. Background technique [0002] The electric vehicle vehicle controller is the core control component of the vehicle. It collects the accelerator pedal, brake pedal, gear position signals and component information, analyzes driving intentions and driving conditions, controls the actions of the lower components, and realizes power-on and automatic control. Check, charge, standby, drive, component coordination, fault judgment and other basic functions of the whole vehicle. [0003] But for now, the common problems of electric vehicle controllers are: in the driving mode of the whole vehicle, the torque management strategy is simple and extensive, and the torque output cannot be finely managed in combination with driving intentions and driving conditions. Affect the po...
