Problems solved by technology
However, when the current automobile is braking, its kinetic energy is converted into heat energy in the brake and dissipated in the atmosphere.
During the daily driving of a large number of cars, especially in the urban driving process with relatively congested traffic, frequent starting acceleration and braking deceleration produce huge braking energy dissipation, which greatly reduces the efficiency of the motor

Embodiment Construction
[0041] To facilitate the description below, first, a description of some basic terms is given:
[0042] ABS: Anti-lock Brake System, ABS is a car safety control system that has the advantages of preventing wheel locking, shortening the braking distance of the car, reducing tire wear, and preventing the car from running off and flicking.
[0043] ECU: Electronic Control Unit, the electronic control unit ECU, is the core controller of ABS. The function of the electronic control unit is to calculate, process and judge the information input by the sensor according to the programs and data in its memory, and then output instructions to the execution parts To provide certain control information, the electronic control unit is composed of a central processing unit, input, output and control circuits.
[0044] CPU: Central Processing Unit, the central processing unit, is the core part of the ECU. It is the control center that calculates, processes, and judges the information input by ...

The invention discloses an integrated ABS (anti-lock brake system) vehicle brake energy recovery system which comprises a vehicle speed sensor, an ECU (electronic control unit), an angle sensor, a regulator, an electromotor, a storage cell and an energy recovery control module. The invention also discloses an integrated ABS vehicle brake energy recovery method which comprises the steps of obtaining a vehicle speed signal; obtaining a pedal angle signal; when a vehicle is driven and is braked, starting an ABS; and carrying out vehicle brake. The integrated ABS vehicle brake energy recovery system disclosed by the invention is organically combined with the ABS when the vehicle is braked; under the situation that the vehicle is safely driven, the vehicle brake energy is recovered, and the integrated ABS vehicle brake energy recovery system has the characteristics of energy saving, environment protection and safety. The integrated ABS vehicle brake energy recovery system and method with excellent performances can be widely applied to the industry in the field of the pure electric vehicles or hybrid electric vehicles.
Description
technical field [0001] The invention relates to vehicle braking energy recovery, in particular to a vehicle braking energy recovery system and method in the field of pure electric vehicles or hybrid vehicles. Background technique [0002] In order to solve problems such as the depletion of oil resources and environmental pollution, break through the bottleneck of automobile development, and achieve sustainable development, people have successively developed various forms of clean vehicles such as alternative energy vehicles, pure electric vehicles, hybrid vehicles, fuel cell vehicles, and solar vehicles. Among energy vehicles, pure electric vehicles and hybrid electric vehicles (Hybrid Electric Vehicle, HEV) have the most popular significance and development potential. Pure electric vehicles are the ultimate choice to replace traditional internal combustion engine vehicles and achieve zero emissions. Although the energy density, charging time, price, lifespan and other issue...
