Problems solved by technology

It uses two controllers, each of which controls two motors to control electric vehicles. Although the control effect is better than that of one controller, it still cannot meet the requirements of multi-motor drive and coordinated control and electric vehicles. High requirements for handling stability, etc., and at the same time, the battery power source and instrument display are not incorporated into the drive control system

Embodiment 1

[0030] see figure 1 , The four-wheel intelligent driving platform for electric vehicles of this embodiment includes a hub motor 1, a motor controller 2, a vehicle controller 3, a battery management system 4, a power battery 5, an input signal sensor 6, an instrument 7, and an instrument controller 8. It forms a complete system with CAN communication network 9. There are four hub motors 1: 1-1, 1-2, 1-3, and 1-4, all of which are permanent magnet brushless DC motors, which are installed in the wheels. Correspondingly, there are four motor controllers 2: 2-1, 2-2, 2-3, 2-4, which control the corresponding motor 1 respectively.

[0031] The bold implementation in the figure is the power line, which is provided by the power battery to the 4 in-wheel motors 1, the 4 motor controllers 2, the vehicle controller 3, the battery management system 4, the instrument 7 and the instrument controller 8. Each controller has a power module inside, which realizes the level conversion of +48V powe...

Abstract

The invention discloses an intelligent drive platform for four wheels of a electric automobile, comprising four hub motors, four motor controllers, a power battery and a controller area network (CAN) communication network; further comprising an entire vehicle controller, wherein the four hub motors, the four motor controllers and the entire vehicle controller are all connected with the power battery; and the entire vehicle controller respectively controls the four motor controllers by the CAN communication network. The entire vehicle controller is located at the core of a distribution type control network, collects the information of each sub-controller and transmits the executed commands to each sub-controller for executing. The intelligent drive platform comprehensively considers the hub motor control, the entire vehicle kinetic control, the battery energy management and the instrument display based on the system and utilizes an advanced flexible control algorithm. The invention hasremarkable effects of improving the comfort performance, the maneuverability and the battery continuous driving capability of the electric automobile.

Description

Technical field [0001] The invention relates to the field of electric vehicle control, in particular to a four-wheel intelligent driving platform based on a hub motor drive. Background technique [0002] In order to solve the increasingly serious energy and environmental problems, automobiles are being developed from traditional internal combustion engines to electric vehicles powered by electric motors. Zero-polluting and high-efficiency electric vehicles have become the current focus of research and development in the automotive field. The main problems currently restricting the large-scale promotion and application of electric vehicles are the short driving range, long charging time, and low power performance of electric vehicles. This solves the bottleneck of the development of electric vehicles. Electric vehicles are developing in the direction of lightness and miniaturization. [0003] Electric vehicles initially used a single motor to provide power. The volume and power of t...
