Many active safety systems in automotive vehicles, for instance yaw stability systems such as ESC/ESP, depend on information about vehicle velocity, in particular lateral velocity or side-slip angle, to be able to function properly. However, the vehicle velocity is rarely measured directly due to issues of cost and reliability, and must therefore in general be inferred from other measurements, ...

The purpose of this paper is to estimate accurately the vehicle attitudes, i.e. the vehicle roll and pitch angles. It is assumed that a set of data obtained from a low-price six-dimensional inertial measurement unit is available. This includes the linear acceleration of the vehicle and the angular rates of all axes. In addition, the observer exploits the data from the wheel speed sensors, and t...

The present study has established equal sensation curves for steering wheel hand-arm rotational vibration. Psychophysical response tests of 20 participants were performed in a steering wheel rotational vibration simulator using the category-ratio Borg CR10 scale procedure for direct estimation of perceived vibration intensity. The test stimuli used were sinusoidal vibrations at 22 third octave ...

the car safety is important for sustainable development of contemporary automobile industry, the researches of the automotive active and passive safety have been universal concern and attention, when the vehicle frontal collision occurred, and the steering wheel and rigid steering column is the main components to make the driver be injured.Based on the extensive collection of home and abroad re...

Beginning with the Pronto4TM Strap-on Autonomy System — a retrofit kit that makes any existing vehicle with a steering wheel a drive-by-wire system — and including a flexible, shared variable software base running on an open architecture system, DesignJug is enhancing its technology by creating a new sensor platform with supporting software that provides input to the team’s Actively Refined Rea...

In this paper, a construction of an efficient vehicle control method for an autonomous vehicle using the power wheeled steering (PWS) method by two driving wheels is described. First, the vehicle dynamics using the PWS method is analyzed. Next, an efficient controller for the PWS method is proposed. This controller includes a feedforward compensator which has the inverse dynamics of the vehicle...

Xiong, Aiping. M.S.I.E., Purdue University, August 2014. Influence of Referential Coding in a Choice Task Performed in a Simulated Driving Cockpit. Major Professors: Robert W. Proctor and Vincent Duffy. Driving and other tasks performed by the driver of a vehicle are spatial. Thus, it is important to understand how the driver represents the spatial environment. In laboratory studies, the Simon ...

This article describes the scope of vehicle dynamics control application on micro-scale electric vehicle for enhancing its active safety. The use of in-wheel-motor control in various control objectives as active safety devices are stated in the paper. In the first half of the paper, the control systems for enhancing vehicle dynamics are described. The active front steering by using steer-by-wir...

Advanced Vehicle Control Systems (AVCS) is a key technology for Intelligent Transportation System (ITS) and Intelligent Vehicle Control System (IVCS). AVCS involves automatic steering, acceleration and braking control of fully autonomous vehicles. The unmanned control of the steering wheel is one of the most important challenges faced by the researchers. This paper proposes control architecture...
