Caterpillar's New D8N Tractor with Differential Steering

SAE Technical Paper Series, 1987
<div class="htmlview paragraph">The D8N track type tractor at 213 kW (285 horsepower) was developed to provide a machine with large tractor features, yet carefully sized to be transported easily. In addition to incorporating the design features of Caterpillar's other large elevated sprocket tractors, the D8N has been equipped with a unique new ...

On the Tracking Control of Differentially Steered Wheeled Mobile Robots

Journal of Dynamic Systems, Measurement, and Control, 1997
Fundamental tracking control algorithms of a differentially steered wheeled mobile robot with two conventional driven wheels are studied through analyzing the robot’s inherent kinematics. This includes the tracking variable assignment as well as the tracking singularity and position-orientation tracking decoupling problems. Globally convergent tracking

Speed-adaptive motion control algorithm for differential steering vehicle

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2020
The differential steering vehicle uses the in-wheel motors to drive the wheels directly and individually. However, in order to deliver the required structural robustness, the differential steering vehicle discarded the mechanical steering system and achieved vehicle steering by applying differential speed between the left and right wheels.

Reduction of Steering Effort in the Event of EPAS Failure using Differential Braking Assisted Steering

SAE International Journal of Transportation Safety, 2017
<div class="section abstract"><div class="htmlview paragraph">Electric Power Assisted Steering (EPAS) is widely adopted in modern vehicles to reduce steering effort. It is probable that some EPAS systems will experience a shutdown due to reliability issues stemming from electrical and/or electronic components.

Robust Model Predictive Control for Differential Speed Steering Vehicles

2019 IEEE Asia-Pacific Conference on Computer Science and Data Engineering (CSDE), 2019
This paper studies the problem of designing robust model predictive control (RMPC) for four-wheel independently driven electric vehicles (FWIDEV) using differential speed steering. The nonlinear dynamic model of the electric vehicle is recast as a linear time-varying polytopic uncertain system.

Crawler Transaxle with Differential Lock and Variable Steering

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">This transaxle is composed of two identical planetaries, a group of speed reducing gears that provide traction drive speed to each planetary through the sun pinions that are on a common shaft. Another group of steering, or differential lock gears provide power into the planetaries through the rotating ring gears ...

Estimation of net traction for differential-steered wheeled robots

Journal of Terramechanics, 2009
Abstract We present a method for estimating the net traction and resistive wheel torques for a suspensionless, differential-steered robot on rigid or deformable terrain. The method, based on extended Kalman–Bucy filtering (EKBF), determines time histories of net traction and resistive wheel torques and wheel slips during steady or transient maneuvers.
