BACKGROUND The purpose of this research was to examine whether waterpipe smokers experience increased risk of motor vehicle crashes. METHODS In a telephone survey, a random sample of Iranian drivers were asked to report their age, gender, vehicle age, whether their vehicles were equipped with anti-lock braking system (ABS), average daily drive time (DDT), whether they smoked cigarette or wate...
As part of the Challenge X competition, the University of Tennessee has chosen a hybrid electric powertrain architecture for conversion of a 2005 Chevrolet Equinox SUV to a more fuel efficient and environmentally responsible vehicle. A brief overview of the powertrain configuration is presented, as well as the corresponding supervisory control system architecture. The methodology for developing...
This paper provides a hierarchical control strategy for cooperative braking system of an electric vehicle with separated driven axles. Two layers are defined: the top layer is used to optimize the braking stability based on two sliding mode control strategies, namely, the interaxle control mode and signal-axle control strategies; the interaxle control strategy generates the ideal braking force ...
When the driving road surface condition suddenly changes from dry to wet, the driving wheels will slip due to much lower coefficient of friction, and thus cause the vehicle to skid. Unlike the popular anti-brake system which applies differential braking to wheels, the presented ant-skid Control properly distributes torques to wheels without braking. In comparison with many recently developed an...
Nowadays, better driving also means better braking. To this end, vehicle designers must find all failures during the design phase of antilock braking systems which play an important role in automobiles safety. However, mechatronic systems are so complex and failures can be badly identified. So it is necessary to propose a design approach of an antilock braking system which will be able to avoid...
Based on the structural features of electric vehicle (EV) driven by in-wheel motors and the characteristics of low speed as well as high torque for in-wheel motors, regenerative braking method for in-wheel motors has been presented. All braking torque for vehicle deceleration is output by in-wheel motors under Medium-intensity braking condition for the sake of recovering the maximum braking ene...
The Automobile Braking System has a crucial role for safety of the passenger and riding quality of the vehicle. The braking force mainly depends on normal reaction on the wheel and the coefficient of friction between the tire and the road surface. Whenever a vehicle is loaded, the normal reaction on the rear wheel is increased. Thus the amount of braking force required to halt the vehicle with ...
This paper presents a collaborative control system for an electric vehicle chassis based on a centralized and hierarchical control architecture. The centralized controller was designed for the suspension and steering system, which is used for improving ride comfort and handling stability; the hierarchical controller was designed for the braking system, which is used for distributing the proport...
