Embodiment Construction

[0017] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but is not limited to the content described below.

[0018] The pure electric vehicle braking energy feedback system based on data redundancy dual controllers provided by the present invention has a structure such as figure 2 As shown, it includes a vehicle controller, an energy management system, an ABS controller, a motor controller, and an energy storage system, wherein: the ABS controller is connected to the motor controller through a data exchange channel CAN bus, and they constitute a data redundancy system. There are two different address codes in each controller and two I / 0 modules with different address codes are connected through the CAN bus, which means that the data states of all CPUs are automatically synchronized.

[0019] The hardware structure of the vehicle controller consists of a microprocessor, an analog signal processing circuit (p...

Abstract

The invention relates to a braking energy feedback system of a full electric vehicle based on data redundancy dual controllers. The system comprises a vehicle controller as well as an energy management system, an energy storage system and a data redundancy system which are controlled by the vehicle controller, wherein the data redundancy system consists of an ABS (Anti-skid Brake System) controller and a motor controller which are connected with each other through a data interaction channel CAN (Controller Area Network) bus, and are simultaneously connected with the vehicle controller through the CAN bus. Regenerated braking force and frictional braking force in a braking process are operated by the ABS controller and the motor controller, and data interaction and optimization between the two controllers is carried out to increase the speed, so that data is prevented from being transmitted from the vehicle controller to the brake controller and the ABS controller, therefore, the deficiency that the best opportunity of brake is always missing caused by too low response speed in a conventional braking process is overcome, the braking energy recycling effect is improved and the response speed and the driving range of the full electric vehicle are increased.

Description

technical field [0001] The invention relates to a braking system of an electric vehicle, is an energy feedback braking system of an electric vehicle, and belongs to the technical field of vehicle braking systems. Background technique [0002] With the development of the times and the gradual improvement of people's economic level and living standards, the use of cars has become more and more popular. In the current situation of soaring oil prices and increasingly stringent international environmental protection requirements, electric vehicles are an inevitable trend in the development of the automotive industry. However, the power battery capacity of electric vehicles is limited, and the battery life has become the focus of attention. The specific energy of the batteries offered on the market today is very low, so that the driving range of electric vehicles cannot be compared with that of gasoline vehicles. To solve this problem, in addition to making a breakthrough in the...
