Four wheeled motor vehicle e.g. industrial vehicle, for e.g. building site, has electronic control unit including auxiliary units decelerating torques to be applied on wheels found at interior or exterior of turning via units, respectively

摘要

#CMT# #/CMT# The vehicle (1) has an electronic control unit (20) coupled to a drive wheel orientation unit and to an electrical control braking unit and activated during turning of the vehicle. The unit has a deceleration unit that decelerates dissymmetrical braking and engine torques to be applied on left and right drive wheels (9, 10) of the vehicle during turning. The unit has auxiliary deceleration units that decelerate braking and engine torques to be applied on the wheels that are found at the interior or exterior of turning via braking and orientation units, respectively. #CMT# : #/CMT# An independent claim is also included for a method for controlling a drive wheel of a four wheeled motor vehicle. #CMT#USE : #/CMT# Four wheeled motor vehicle e.g. military vehicle and industrial or agricultural vehicle, for transporting load in factory or building site. #CMT#ADVANTAGE : #/CMT# The design of the vehicle permits to control skidding of the vehicle during failure of an electrically actuated steering column of the vehicle, in an efficient manner. The electronic control unit permits to assist the steering column of the vehicle for optimizing the performance of the vehicle during turning and to possess a degraded mode for orienting the vehicle in case of failure of the electric control of an electrical steering actuator. The design of the vehicle permits to improve safety of a driver and to increase his enjoyment of driving. The device is compatible with different types of engine. The control unit is activated during turning of the vehicle, thus permitting the vehicle to be controlled in case of failure of the actuator of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block representation of a part of a four wheeled motor vehicle with a steering system. 1 : Four wheeled motor vehicle 2 : Heat engine 3 : Gear box 9 : Left drive wheel 10 : Right drive wheel 20 : Electronic control unit.
