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 drive platform for electric vehicles in this embodiment includes an in-wheel 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 A complete system that forms with CAN communication network 9. There are four in-wheel motors 1: 1-1, 1-2, 1-3, and 1-4, all of which are permanent-magnet brushless DC motors installed in the wheels respectively. Correspondingly, there are four motor controllers 2: 2-1, 2-2, 2-3, and 2-4, which respectively control the corresponding motor 1.
[0031] The rough implementation in the figure is a power line, which is provided by the power battery to 4 in-wheel motors 1, 4 motor controllers 2, vehicle controller 3, battery management system 4, instrument 7 and instrument controller 8. Each controller has a power module inside to realize level conversion from +48V power voltage to...

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 drive platform driven by hub motors. Background technique [0002] In order to solve the increasingly serious energy and environmental problems, automobiles are developing from traditional internal combustion engines to electric vehicles powered by electric motors. Zero-pollution, high-efficiency electric vehicles have become a hot spot in the current research and development of the automotive field. At present, the main problems that restrict the large-scale promotion and application of electric vehicles are short driving range, long charging time, and low power performance of electric vehicles. To solve the bottleneck of electric vehicle development, electric vehicles are developing in the direction of light weight and miniaturization. [0003] Electric vehicles initially use a single motor to provide power. The size and power of the motor are re...
