differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...

According to the independence, accuracy and controllability of the driving/braking torque of the distributed drive electric vehicle, a control strategy of differential drive assisted steering was designed. Firstly, the assisted curve under different speed and steering wheel torque was developed and the differential torques were distributed to the right and left front wheels. Then the steering r...

An automatic steering controller was installed on a Case-IH Model 7220 tractor. The primary posture sensor was a kinematic differential GPS. Open loop and closed loop frequency response tests were conducted to evaluate the steering controller dynamics. A double integrator transfer function adequately related vehicle lateral deviation to steering angle within the frequency range of 0.04 Hz to 0....

Using an Electric Differential (ED) in electric vehicle has many advantages such as flexibility and direct torque control of the wheels during cornering and risky maneuvers. Despite its reported successes and advantages, the ED has several problems limits its applicability, for instance, an increment of control loops and an increase of computational effort. In this paper, an electric differenti...

Steering assist system controls the force transfer behavior of the steering system and improves the steering probability of the vehicle. Moreover, it is an interface between the diver and vehicle. Fault detection in electrical assisted steering systems is a challenging problem due to frequently use of these systems. This paper addresses the fault detection and reconstruction in automotive elect...

This paper presents the design of a CMOS RF Power Detector (PD) using 0.18 μm standard CMOS technology. The PD is an improved unbalanced source coupled pair incorporating an output differential amplifier and sink current steering. It realizes an input detectable power range of −30 to −20 dBm over 0.1–1 GHz. Also it shows a maximum data rate of 30 Mbps with 2 pF output loading under OOK modulati...

When building the robot for outdoor competition the designer can choose from a variety of chassis. The differential drive and Ackerman steering drive are among the most popular. The paper describes our experiences with the custom built chassis that uses Ackerman steering principle together with independently driven back wheels. The chassis represent the base of Bender II mobile robot, used in R...
