Problems solved by technology

However, the energy recovery rate of this control method is generally low, and the increase in driving mileage is very small, and when braking on a road surface with a low adhesion coefficient, it is easy to cause the vehicle to slip, increasing the probability of wheel locking, and it is difficult to take care of braking stability and maximum energy recovery

Abstract

The invention discloses a braking energy recovery control method and device and an electromobile. The method includes the steps that the mode which the electromobile is in is judged; if the electromobile is in a braking state, speed of the electromobile is obtained, and the speed segment which the electromobile is in is judged according to the speed of the electromobile; if the speed of the electromobile is in a first preset speed segment, first preset torque is adopted for braking control over the electromobile; if the speed of the electromobile is in a second preset speed segment, first preset power is adopted for braking control over the electromobile. More energy can be recovered through the braking energy recovery control method in the embodiment, and stability of electromobile braking can be ensured.

Description

technical field [0001] The invention relates to the technical field of energy recovery, in particular to a braking energy recovery control method, device and electric vehicle. Background technique [0002] The braking energy recovery function is a unique technology of electric vehicles. Its function is to convert a part of the mechanical energy of the electric vehicle during deceleration or braking into electrical energy through the drive motor system and store it in the power battery under the premise of ensuring the driving stability of the electric vehicle. Or provide the electricity demand of electric vehicle electrical equipment. In related technologies, a parallel energy recovery control method is adopted, which maintains the structure of the traditional electric vehicle braking system, and adopts independent control of mechanical braking force and electric braking force, and the two do not affect each other during normal driving. However, the energy recovery rate of ...
