Problems solved by technology

[0004] However, the existing four-wheel drive system is easy to ensure the driving force on slopes or roads with low friction coefficient, but the driving force is only limited to the longitudinal direction. When turning or changing lanes, the four-wheel drive system has little impact on vehicle stability.

Abstract

The invention provides a wheel driving system using an acceleration sensor and a vehicle with the system. The wheel system judges the motion of the vehicle according to longitudinal acceleration and transverse acceleration and sets a torque vector distribution mode for controlling the running of the vehicle. The wheel driving system comprises an acceleration data calculating part calculating the vehicle acceleration data based on the longitudinal acceleration and the transverse acceleration, an area distinguishing part judging the motion state of the vehicle based on the acceleration data, a torque vector distribution determining part determining the vehicle torque vector distribution mode based on the motion state, and a vehicle driving controller distributing driving force to each wheel of the vehicle based on the torque vector distribution mode and controlling the motion of the vehicle based on the driving force distributed to each wheel.

Description

technical field [0001] The present invention relates to a wheel drive system capable of distributing driving force to each wheel of a vehicle, and a vehicle equipped with the wheel drive system. Background technique [0002] The electronically controlled four-wheel drive system is a system that only uses the front or rear wheels to drive, but when the driving wheels slip, it distributes the engine torque to the rear or front wheels to ensure the driving wheels. However, it also operates according to the driver's acceleration will and steering operation to ensure vehicle driving force. [0003] Korean Patent Publication No. 2009-0051317 relates to the power transmission structure of a four-wheel vehicle. When the front wheel is the main driving force and all four wheels need to be driven, a multi-plate clutch is operated to distribute the driving force to the rear wheel, and the clutch is adjusted according to the slip rate of the clutch. The distribution of driving force. ...
