Abstract

The invention provides a braking energy recycling method used for a light electric vehicle. The braking energy recycling method comprises the steps that the driving state parameters of the light electric vehicle are detected; and when the light electric vehicle is braked, different energy recycling strategies are executed according to the driving states of the light electric vehicle. The invention also discloses an energy recycling system (200). The energy recycling system (200) comprises an anti-lock controller (212) and an electronic control device (101') of a driving system. The anti-lock controller (212) sends the vehicle driving state parameters to the electronic control device (101'), and the electronic control device (101') controls the energy recycling system (200) to conduct braking energy recycling. The invention further discloses an electronic control device body (101). According to the braking energy recycling method, the energy recycling system (200) and the electronic control device body (101), the different energy recycling strategies can be set under the different driving states in the braking process of the light electric vehicle especially after an anti-lock system intervenes the control, so that most effective braking energy recycling is achieved in the braking process of the light electric vehicle, and meanwhile, the braking performance of the light electric vehicle is combined.

Description

technical field [0001] The invention relates to the field of driving control of light electric vehicles, in particular to a braking energy recovery device and method; the invention also relates to a light electric vehicle. Background technique [0002] Light electric vehicles include electric scooters, electric bicycles, electric mopeds, electric motorcycles, etc. In recent years, light electric vehicles with batteries and motors as the driving energy, usually weighing less than 100 kilograms, and having two or three wheels have been greatly developed. The driving speed of light electric vehicles is relatively fast, the driving conditions are relatively complicated, and they will be restricted by terrain and traffic conditions during driving. The driver needs to brake at any time according to the road conditions to slow down or stop the vehicle. In order to increase the cruising range, light electric vehicles usually include energy recovery devices. The principle of most e...
