Embodiment Construction

[0027] It should be noted that the features of the present invention and the features in the present invention can be combined with each other in the case of an unable conflict.

[0028] The present invention will be described in detail below with reference to the drawings.

[0029] figure 1It is a flow chart of an adaptive control method of the energy recovery intensity of the vehicle according to an embodiment of the present invention. like figure 1 As shown, the method includes:

[0030] Step S11, when the accelerator pedal and the brake pedal of the vehicle are detected, the front road condition information of the vehicle and the vehicle speed of the vehicle are detected;

[0031] For example, when the accelerator pedal and the brake pedal are not stepped on, the vehicle can perform sliding energy recovery. At this time, the embodiment of the present invention can detect front road conditions to determine the appropriate deceleration of the vehicle for energy recovery. The fr...

Abstract

The invention relates to the technical field of vehicle control, and provides a self-adaptive control method and device for energy recovery intensity of a vehicle. The self-adaptive control method for the energy recovery intensity of the vehicle comprises the steps that when an accelerator pedal and a brake pedal of the vehicle are detected not to be stepped down, front road condition information of the vehicle and the vehicle speed of the vehicle are detected; according to the front road condition information and/or the vehicle speed of the vehicle, an ideal deceleration meeting the requirement of the front road condition information is determined; and the deceleration of the vehicle is controlled according to the ideal deceleration and the deceleration limit of energy recovery so as to carry out energy recovery. According to the invention, intelligent energy recovery can be realized.

Description

Technical field [0001] The present invention relates to the field of vehicle control technology, and more particularly to an adaptive control method and apparatus of an energy recovery intensity of a vehicle. Background technique [0002] At present, the energy recovery function is configured to effectively improve energy recycling function during the deceleration process, and the kinetic energy of the accelerator pedal is converted into electrical energy storage and used to drive. The three-stage recovery intensity of the energy recovery function of the existing vehicle is manually adjustable. After activating the energy recovery function and selects a certain recovery, the vehicle will only control the vehicle deceleration and intelligent. The degree is not high. Inventive content [0003] In view of this, the present invention is directed to present an adaptive control method of an energy recovery intensity of a vehicle to achieve intelligent energy recovery. [0004] In orde...
