Abstract
The present invention discloses an electric automobile feedback brake control method which aims to provide a method for controlling feedback by detecting the speed of an electronic accelerator pedal which is released by a driver. The present invention comprises an accelerator pedal, and is characterized in that the accelerator pedal is an electronic accelerator pedal. The whole method is composed of the following steps that in the first step, the driver steps the travel range of the electronic accelerator pedal, and the travel range is fed back to a controlling unit by an electrical signal form; in the second step, the size of expected feedback brake blockage torque is calculated, and sliding weighted average of lifting speed in a section of time before the driver lifts the accelerator pedal to a feedback brake starting position which is preset is calculated to be used as the size of the expected feedback brake blockage torque; in the third step, a motor is controlled according to the expected feedback brake blockage torque to complete the control of the driver to feedback brake.
Description
Technical field
The present invention relates to a kind of control method of electronlmobil, more particularly, it relates to a kind of electronlmobil regeneration braking control method.
Background technology
Along with the raising of people's living standard, automobile obtains use more and more widely, and simultaneously people require also more and more highlyer to the clear energy sources of automobile, and automobile positive comfortableization, lightweight, motorized, energy cleaningization direction and developed.Electronlmobil with energy storage member can be converted into power storage in energy storage member with the kinetic energy of automobile by the electric energy feedback function of motor in braking procedure, can realize the recovery of braking energy with this, reach purpose of energy saving, the intensity of regenerative braking is generally controlled by motor, the size that is the size of regenerative braking moment and feedback electric current is all by control break, the control method of traditional electric automobile regenerative braking mainly contains dual mode, a kind of is that another kind is to control by brake pedal by acceleration pedal control.
By the acceleration pedal mode mainly is that the brake system of considering present automobile still comprises pneumatic and hydraulic way based on machinery, and the collaborative work of regenerative braking and mechanical braking mechanism need be carried out bigger change to brake pedal, therefore present motor-driven electronlmobil adopts an electronic accelerator pedal to control the acceleration and the regenerative braking of motor simultaneously mostly, but because regenerative braking intensity control method is established the regenerative braking stroke, the position signal of acceleration pedal was not the size that is used for controlling moment of accelerating in this was interval, but was used for controlling regenerative braking intensity.This control method operability is good, simple and practical, but shortcoming is that pedal must not meet the driving habit of traditional combustion engine automobile at first by the regenerative braking stroke in the accelerator, and the subjective sensation of chaufeur is bad.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of control method not establish the regenerative braking stroke, but decontrol a kind of electronlmobil regeneration braking control method that the speed of acceleration pedal is controlled feedback intensity by detecting chaufeur.
A kind of electronlmobil regeneration braking control method is characterized in that acceleration pedal is an electronic accelerator pedal, and its method comprises the following steps:
The first step: the stroke of chaufeur being trampled electronic accelerator pedal feeds back to control unit with the form of electric signal;
Second step: calculation expectation regenerative braking resistive torque size
Calculate chaufeur in the control unit and lift the moving weighted average that acceleration pedal arrives the speed of lifting in the whole time period before the predefined regenerative braking starting position, the promptly new speed constantly of moving weighted average is than the bigger weights of front moment speed, ask the aviation value after each speed weighting constantly then, as the expectation regenerative braking resistive torque size of chaufeur;
The 3rd step:, finish the control of chaufeur to regenerative braking according to expectation regenerative braking resistive torque control motor.The invention has the beneficial effects as follows:
The present invention quickens and regenerative braking moment by electronic accelerator pedal control motor, the automobile mechanical brake system is not changed, simple and reliable, because of having cancelled the regenerative braking stroke on the acceleration pedal, therefore the driving habit that meets the traditional combustion engine automobile, grasp easily and control, the present invention is applicable to by various vehicles electric motor driven, that have energy storage member, comprises pure electric automobile, hybrid vehicle, fuel cell powered vehicle etc.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
Characteristics of the present invention are, acceleration pedal is an electronic accelerator pedal, and its method comprises the following steps:
The first step: the stroke of chaufeur being trampled electronic accelerator pedal feeds back to control unit with the form of electric signal;
Second step: calculation expectation regenerative braking resistive torque size
Calculate chaufeur in the control unit and lift the moving weighted average that acceleration pedal arrives the speed of lifting in the whole time period before the predefined regenerative braking starting position, the promptly new speed constantly of moving weighted average is than the bigger weights of front moment speed, ask the aviation value after each speed weighting constantly then, as the expectation regenerative braking resistive torque size of chaufeur; The 3rd step:, finish the control of chaufeur to regenerative braking according to expectation regenerative braking resistive torque control motor.
Implementation method of the present invention:
Electronlmobil adopts a kind of method of electronic accelerator pedal control regenerative braking intensity, this control method is not established the regenerative braking stroke, but feed back to control unit with the form of electric signal by detecting stroke that chaufeur tramples electronic accelerator pedal, calculate chaufeur in the control unit and lift the moving weighted average that acceleration pedal arrives the speed of lifting in the whole time period before the predefined regenerative braking starting position, the promptly new speed constantly of moving weighted average is than the bigger weights of front moment speed, ask the aviation value after each speed weighting constantly then, expectation regenerative braking resistive torque size as chaufeur, according to expectation regenerative braking resistive torque control motor, finish the control of chaufeur to regenerative braking.
This control method controls simultaneously by electronic accelerator pedal that motor quickens and the characteristics of regenerative braking moment, and the automobile mechanical brake system is not changed, and is simple and reliable.In addition, cancelled the regenerative braking stroke on the acceleration pedal, therefore met the driving habit of traditional combustion engine automobile, allowed chaufeur accept easily.
