Problems solved by technology

Although traditional four-wheel drive vehicles have better power and off-road performance than conventional two-wheel drive vehicles, their fuel consumption and emissions are relatively high, which can no longer meet the development requirements of modern automobiles for energy saving and emission reduction. Therefore, major automobile manufacturers have begun to compete. Phase development of four-wheel drive hybrid vehicles to replace traditional fou...

Embodiment Construction

[0037] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0038] The coordinated control technology of the electronic four-wheel drive system of this embodiment utilizes the coordinated control of the vehicle controller and the electronic stability system (ESP) to realize the reasonable distribution of front and rear axle torques in various drive modes of the four-wheel drive hybrid electric vehicle, ensuring the stability of the vehicle. Handling stability; at the same time, optimize the working mode of the four-wheel drive vehicle to make it more economical. The four-wheel-drive hybrid vehicle includes an engine and an ISG motor arranged in parallel on the front axle, a rear-drive motor arranged on the rear axle, and a high-voltage battery providing power for the rear-drive motor and the ISG motor. The driving modes include pure electric (EV) m...

Abstract

The invention relates to an electronic all-wheel-drive system for a motor vehicle and a control method therefor. The electronic all-wheel-drive system comprises a whole vehicle system, a power control system and an ESP (Electronic Stability Program) module, wherein, the ESP module is connected with the whole vehicle system and the power control system through a whole vehicle CAN (Controller Area Network) bus in a controlling manner; the power control system comprises an engine management system (EMS), a battery management system (BMS), a rear-guard motor controller (TM), A motor control unit (MCU) and a transmission case control unit (TCU); the power control system is used for interacting with the whole vehicle system, acquiring the state information of the whole vehicle system, outputting control commands after judging and processing, and controlling the whole vehicle system to operate; the whole vehicle system comprises a rear-guard motor, a high-tension battery, an ISG (Integrated Starter Generator), an engine and a transmission case.

Description

technical field [0001] The invention belongs to the field of hybrid electric vehicle control, and relates to a system coordination control technology of an electronic four-wheel drive hybrid electric vehicle, in particular to an electronic four-wheel drive system of a motor vehicle and a control method thereof. Background technique [0002] With the further aggravation of energy crisis and environmental deterioration, energy saving and environmental protection have become the themes of modern automobile development. Although traditional four-wheel drive vehicles have better power and off-road performance than conventional two-wheel drive vehicles, their fuel consumption and emissions are relatively high, which can no longer meet the development requirements of modern automobiles for energy saving and emission reduction. Therefore, major automobile manufacturers have begun to compete. Phase development of four-wheel drive hybrid vehicles to replace traditional four-wheel driv...
