Development of a new all-wheel drive control system
free download

The new all-wheel drive control system has been developed to improve stability on slippery road and handling performance on dry road. This control system realized advanced safety and controllability in the aspect of vehicle dynamics under various road/operating

All-Wheel Drive/Four-Wheel Drive Systems and Strategies
free download

Modern Four-Wheel Drive (4WD) systems have become very sophisticated and infused with electronic control technology. These 4WD vehicles offer the appeal of an active lifestyle made possible by the assurance of a safe and secure vehicle, onand off-road, along with

Challenges of an electronically distributed all wheel drive on basis of a retrofit full hybrid 4WD solution
free download

Abstract One important task of electrification of vehicle powertrain is the functional integration of all new systems in respect of the performance, comfort and emission restrictions. In this particular case, starting from a mass produced vehicle platform in the

Traction Control of All-Wheel-Drive Independent Suspension Mobile Robots in 2D Rough Terrain
free download

Abstract. Traction control is a critical aspect of mobile robots that need to traverse rough terrain, avoiding excessive slip which may cause the terrain to collapse locally and trap the robot wheels and guaranteeing an adequate trajectory and speed control while reducing

Traction dynamics of the all-wheel drive machine tractor unit with hinged soil processing equipment
free download

Summary. In the article methodical positions of the parametrical analysis of dynamics of the all-wheel drive machine tractor unit (MTU) including hinged soil processing equipment with active working bodies (AWB) are performed. Keywords: tractor's hinged unit, soil

Study on increasing braking performance and efficiency of four-wheel-drive tractors through braking on all wheels
free download

Abstract:The paper elaborates a mathematical model with a view to carrying out a study into the dynamics of wheeled tractors during braking. The braking dynamics is analyzed by considering two versions for the braking system: 1) braking applied on the rear axle and 2)

Fuel Economy Improvement of an Electric All Wheel Drive System (e-AWD)
free download

E-AWD hybrid system can be defined as a system has hybrid system in front, motor driving system in rear. As an example, RX450h and Highlander hybrid of Toyota have THS system in front, motor driving system in rear. Advantage of this system is high fuel economy (

WHEEL SLIP CONTROL FOR ALL-WHEEL DRIVE ELECTRIC VEHICLE
free download

Abstract Development of wheel slip control for ground vehicles with electric powertrain belongs to one of the most challenging problems in automotive control engineering. The realization of wheel slip control for anti-lock brake (ABS) and traction control (TC) systems

DYNAMIC DAMPING TORSIONAL VIBRATIONS IN THE TRANSMISSION OF REAR-WHEEL DRIVE AND ALL-WHEEL DRIVE VEHICLES
free download

ABSTRACT A new system of dynamic absorption of vibrations in the vehicle's transmission is observed in this article. The proposed solution provides the absorption of torsional vibrations near the resonance frequency. The basis of the kinematic scheme is based on

Control Software Optimization for a Multi-Clutch System in a Hybrid All Wheel Drive Vehicle
free download

Abstract: The hybrid vehicles are already since some years on the market,target of reducing fuel consumption and emission. An innovative four wheel drive hybrid drivetrain was developed in MAGNA STEYR, with the additional aim to improve performances and

ALL WHEEL DRIVE COMPONENTS MODELLING AND THEIR INFLUENCE ON VEHICLE DYNAMICS
free download

ABSTRACT The goal of the activity consists in modelling the most commonly used active and passive differentials, and in the evaluation of their influence on vehicle dynamics. The models here presented are not only functional models, giving origin to precise output

Analysis of Possible Ways of Power Distribution in an All-wheel Drive Vehicle
free download

Abstract:The main indicators for mobility of a multipurpose wheeled vehicle are the maximum and average technical velocity, and they are mainly determined by power- toweight ratio and the parameters of the suspension. As our analysis shows, with the

A Rough Terrain Traction Control Technique for All-Wheel-Drive Mobile Robots
free download

Traction control is a critical aspect of mobile robots that need to traverse rough terrain, avoiding excessive slip which may cause the terrain to collapse locally and trap the robot wheels and guaranteeing an adequate trajectory and speed control while reducing the

ENHANCEMENT OF ENERGY EFFICIENCY, VEHICLE SAFETY AND RIDE COMFORT FOR ALL-WHEEL DRIVE FULL ELECTRIC VEHICLES
free download

ABSTRACT The optimal brake control in the case of a full electric vehicle must not only guarantee high brake performance but also aim at maximum possible level of energy regenerated during the manoeuvre.targeting integrated electric vehicle control, the

Efficient Power Distribution in an All-wheel Drive Truck
free download

Abstract:This paper is devoted to development of methodology of system analysis of power distribution systems and development of methods of synthesis of objective laws in the power

Differential Control Strategy based on an Equal Slip Rate for an All-wheel Electric-driveUnderground Articulated Dumping Truck
free download

Abstract A differential control strategy based on equal slip rates is introduced to improve the steering stability of an all-wheelelectric-drive underground articulated dumping truck. Steering kinematic and dynamic models of the truck are derived to describe the movement
