Embodiment Construction

[0032] Starting from existing driving habits, the present invention uses an electric vehicle acceleration control device (such as the accelerator pedal of an electric vehicle, the accelerator knob of an electric bicycle, etc.) The deceleration energy is effectively recovered. Since when driving a vehicle, the usual intent of releasing the accelerator control is to slow down, the recuperated energy is now fully consistent with the driving intent.

[0033] Such as figure 1 Shown is a schematic diagram of an embodiment of the electric vehicle kinetic energy recovery control system of the present invention. The electric vehicle in this embodiment includes a motor 13 that drives the wheels 15 to rotate, a motor driver 12, an acceleration control device 11, and a battery 14 for power supply, wherein the motor driver 12 converts the direct current of the battery 14 into alternating current to control the operation of the motor 13 .

[0034] Above-mentioned electric vehicle can be ...

Abstract

The invention relates to a kinetic energy recovery control system of an electric vehicle. The electric vehicle comprises a motor for driving wheels to rotate, a motor driver, an acceleration controller, a battery for supplying power and a feedback control unit, wherein the feedback control unit is used for controlling the motor to output a negative torque through the motor driver when the motor is in a working state and the acceleration control device is in a loosening device; and the battery is charged by the output of the motor through the motor driver. The invention also provides a corresponding kinetic energy recovery method and the electric vehicle. According to the invention, the motor is controlled to output the negative torque through the motor driver when the acceleration control device is loosened, so as to provide a deceleration braking torque for the whole vehicle; meanwhile, the driving motor is dragged, by means of the inertia of the whole vehicle, to generate power, and therefore the electric vehicle is more energy-saving and environment-friendly in the using process.

Description

technical field [0001] The invention relates to the field of electric vehicle control, and more specifically relates to a control system and method for kinetic energy recovery of an electric vehicle. Background technique [0002] In recent years, under the influence of global environmental problems and transportation environmental problems, more and more attention has been paid to battery-driven vehicles (such as electric vehicles, electric bicycles, etc.). At present, electric vehicles have become the most promising new energy vehicles after internal combustion engine vehicles, and various governments and major automobile companies around the world have regarded electric vehicles as the future development direction. [0003] In the existing motor drive control strategy of electric vehicles, in order to take into account the traditional braking system (for example, many fuel-point hybrid vehicles currently exist), the motor driving the vehicle usually only works in the elect...
