Embodiment 1

[0040] refer to figure 1 , the diagram is a flow chart of Embodiment 1 provided by the energy recovery method in the embodiment of the present invention, and the energy recovery method includes the following steps:

[0041] Step S101: The vehicle controller receives the accelerator pedal opening value collected by the sensor module, and proceeds to step S102.

[0042] Step S102: The vehicle controller judges whether the opening of the accelerator pedal is greater than a set value, if the opening of the accelerator pedal is greater than the set value, go to step S103; otherwise, go to step S104.

[0043] Step S103: The accelerator pedal opening value is greater than the set value, the motor controller controls the motor to output positive torque to drive the electric vehicle, and converts the electric energy of the electric energy storage into the kinetic energy of the electric vehicle during the process.

[0044] Step S104, otherwise, the motor controller controls the motor t...

Embodiment 2

[0054] refer to image 3 , the diagram is a flow chart of the method of Embodiment 2 that is further improved on the basis of Embodiment 1 of the present invention, and the energy recovery method includes the following steps:

[0055] Step S201: The vehicle controller receives the sensor signal collected by the sensor module, the sensor signal includes: accelerator pedal opening value, motor voltage value, motor speed value, brake pedal opening value, electric energy storage voltage value, And go to step S202.

[0056] Step S202: The vehicle controller judges whether the working state of the motor is normal, if the working state of the motor is normal, the motor continues to work, and enters step S204; otherwise, controls the motor to stop working, and enters step S204 S203.

[0057] Step S203: alarm prompt and display fault information.

[0058] Step S204: Judging whether the opening of the accelerator pedal is greater than a set value, if the opening of the accelerator pe...

Abstract

The invention discloses a car energy recovering method and device and relates to the technical field of cars. The method comprises the steps that a car controller receives an accelerator pedal openingvalue collected by a sensor module; the car controller judges whether the accelerator pedal opening value is larger than a set value or not; and if the accelerator pedal opening value is larger thanthe set value, a motor controller controls a motor to output positive torque so as to drive an electric car, and in the process, electric energy stored by an electric energy storing device is converted into kinetic energy of the electric car. According to the car energy recovering method and device, through an accelerator pedal in the electric car, the two functions of driving and braking are simultaneously achieved, thus the energy recovering efficiency is improved, and the endurance mileage is increased.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for energy recovery of automobiles. Background technique [0002] With the popularization of electric vehicles and the improvement of the requirements for the cruising range of electric vehicles, there have been many technologies for increasing the cruising range, among which the regenerative braking system has the most obvious effect. The existing regenerative braking system mainly takes effect after stepping on the brake pedal, thereby converting the kinetic energy of the vehicle into electrical energy and storing it in a supercapacitor or power battery. [0003] But there is a problem, because the brake pedal needs to be stepped on, while the regenerative braking system is in effect, the traditional mechanical system has also been in effect, resulting in low efficiency of energy recovery. Contents of the invention [0004] In view of this, the embodi...
