Embodiment Construction

[0027] In order to make the objects, technical solutions, and advantages of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like figure 1 As shown, a schematic diagram of one embodiment of a method of achieving a dragging sensor is provided in the present invention. In this embodiment, the method comprises the steps of:

[0029] Step S1, the VCU detects the power signal and energy recovery status signal of the vehicle internal battery pack through the CAN bus;

[0030] In particular, the power signal and energy recovery state signal of the vehicle internal battery pack are specifically detected that the VCU detects the voltage of the battery pack positive and negative two poles, or the signal can be detected, such as voltage. The corresponding current lighting signal and whether the power signal is normal, and the voltage value of the battery pack is processed by the voltage of the posit...

Abstract

The invention provides a method and system for achieving the dragging sense of an electric vehicle and the electric vehicle, and the method for achieving the dragging sense of the electric vehicle comprises the steps that S1, a VCU obtains an electric quantity signal and an energy recovery state signal of a vehicle battery pack; S2, the VCU detects whether the electric quantity of the battery is full or not according to the electric quantity signal and detects whether the energy recovery function fails or not according to the energy recovery signal, when the electric quantity of the battery is full or the energy recovery function fails, the vehicle cannot conduct energy recovery, and the VCU outputs a signal that energy recovery cannot be conducted to the ESP; and S3, after the ESP receives the signal that the VCU cannot recover energy, whether the vehicle is in a sliding state or not is detected, and if the vehicle is in the sliding state, a dragging force is provided for the vehicle through active pressurization of calipers. The dragging sense of the electric vehicle during running is kept consistent with that of a traditional vehicle, and the driving experience is improved.

Description

Technical field [0001] The present invention relates to the field of electric vehicle control technology, and more particularly to a method, system, and electric vehicle for an electric vehicle to achieve a dragging sensation. Background technique [0002] Compared with traditional vehicles, there is no dragging feeling in the sliding, in order to improve the driving experience on this working condition, it is generally generally a sloppy in the sliding energy to simulate the whole vehicle in sliding; but the vehicle is full of power Or the energy recovery is not possible to improve the driving experience through taxi energy. [0003] The prior art is: Publication No. CN108639037A (electrical power compensation control method, controller, electric assisting system, car); publicly disclosed electric brake compensation control method, including: receiving motor controller MCU transmission A auxiliary brake request and the detection information transmitted by the body electron stabi...
