Hub motor-driven electric automobile with independently modularized whole vehicle controller and control method of electric automobile

Abstract

The invention discloses a hub motor-driven electric automobile with an independently modularized whole vehicle controller. The hub motor-driven electric automobile comprises a plurality of wheels, a plurality of hub motors, a plurality of steering motors, a hub motor controller, a steering motor controller, the whole vehicle controller and an auxiliary function controller; the plurality of wheelsare connected with an automobile body through a suspension frame; the plurality of hub motors are installed in the wheels respectively and are used for independently driving the wheels to rotate; theplurality of steering motors are used for driving the wheels to realize deflection; the hub motor controller is used for outputting torque control signals of the hub motors; the steering motor controller is used for outputting cornering control signals of the steering motors; the whole vehicle controller is internally provided with driving preference information of a driver and is electrically connected with the hub motor controller and the steering motor controller; and the auxiliary function controller is electrically connected with the whole vehicle controller and is used for correcting control signals output by the hub motor controller and the steering motor controller according to the driving preference information. The invention further provides a control method of the hub motor-driven electric automobile with the independently modularized whole vehicle controller.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an electric vehicle driven by a hub motor with an independent modular vehicle controller and a control method thereof. Background technique [0002] With the continuous development and progress of modern society and living standards, cars have already become an indispensable part of people's daily life. In recent years, due to the continuous aggravation of energy crisis and environmental pollution, electric vehicles have been widely promoted and developed. As a kind of electric vehicles, in-wheel motor-driven electric vehicles integrate the driving motor and even suspension structures inside the wheels. And each wheel is completely independent and controllable, which further enables the vehicle to realize a modular configuration and can give full play to the driving performance of the vehicle, so it is also widely regarded as the final form of automobile dev...

AI Technical Summary

Problems solved by technology

In addition, there must be obvious differences in driving performance between different vehicles, such as the same driver operations such as driving, braking, and steering, but the actual feedback of the vehicles is significantly different.

For traditional vehicles, these are related to factors such as the hardware structure of the vehicle's actual relevant functions and related parameters of the vehicle, so these cannot be changed after the vehicle leaves the factory.

This has led to drivers being limited by the attributes of the vehicle itself when driving different vehicles, requiring the driver to gradually adapt to the vehicle, which must be a problem that needs to be solved
