Embodiment Construction

[0084] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0085] figure 1 is a flowchart of a vehicle braking energy feedback control method according to an exemplary embodiment of the present disclosure, as shown in figure 1 As shown, the method includes steps S101 to S104.

[0086] In step S101, it is determined whether the vehicle needs to enter a curve braking energy feedback mode according to the driving state information of the vehicle. The vehicle driving state information may include, for example, the current vehicle speed, gear position, steering wheel angle, etc., which can at least determine that the vehicle is currently in a curve. According to the vehicle driving state information, it can be determine...

Abstract

The invention relates to a method and device for controlling vehicle braking energy feedback and a vehicle, and relates to the field of vehicles. The method comprises the following steps: according tothe vehicle running state information, judging whether the vehicle needs to enter a braking energy feedback mode in a curve, when judging that the vehicle needs to enter the braking energy feedback mode in the curve, calculating a critical safe vehicle speed capable of ensuring the safe running of the vehicle; according to the critical safe vehicle speed, the current vehicle speed of the vehicleand the opening degree of a brake pedal, determining a feedback moment in the curve required by ensuring the safe running of the vehicle; carrying out braking energy feedback control in the curve on the vehicle according to the curve feedback torque. According to the method, the braking energy feedback in the curve can be maximized when the vehicle runs on the curve, and the running safety of thevehicle can be ensured, so that the effects of saving energy and increasing the endurance mileage can be better achieved.

Description

technical field [0001] The present disclosure relates to the vehicle field, in particular, to a vehicle braking energy feedback control method, device and vehicle. Background technique [0002] The braking energy feedback function is a typical feature of the vehicle, which can convert the mechanical energy during the braking process into electrical energy and store it in the power battery, so as to achieve the effect of saving energy and increasing the cruising range. The braking energy feedback method often used in current vehicles can adopt different braking feedback torque calculation methods for different driving conditions, such as straight roads, slopes and other road conditions, but there is no braking energy feedback for curved road conditions method, so that the braking energy of the electric vehicle in the curve cannot be effectively recovered. Contents of the invention [0003] The purpose of the present disclosure is to provide a vehicle braking energy feedbac...
