The effect of antilock braking systems (ABS) on motorcyclist fatal crash risk in 2005-06 was studied by comparing fatal crash rates per registrations of motorcycles with and without ABS. Study motorcycles included those for which ABS was optional equipment and could be identified as present by the model name. Fatal motorcycle crashes per 10,000 registered vehicle years were 38 percent lower for...

In this paper we derive a new dynamic friction force model for the longitudinal road/tire interaction for wheeled ground vehicles. The model is based on a dynamic friction model developed previously for contact-point friction problems, called the LuGre model [7]. By assuming a contact patch between the tire and the ground we develop a partial differential equation for the distribution of the fr...

Article history: Received 2 April 2013 Received in revised form 25 July 2013 Accepted 26 July 2013 Available online xxxx Since the 1970s, automobile manufacturers have used electronics for safety–critical automobile control systems such as acceleration, braking, and steering. These electronic systems introduced functionalities in automobiles that were not feasible in a purely mechanical framewo...

A vehicle with a four-channel anti-lock braking system (ABS) has poor safety and stability when on low-adhesion road or off-road. In view of this situation, paper proposes multi-objective optimization coordinated control method for ABS AFS based multi-agent model predictive (MPC). Firstly, the single-wheel is adopted to establish equation slip rate centroid yaw AFS. The four wheels are regarded...

The appearance of active safety systems, such as Anti-lock Braking System, Traction Control System, Stability Control System, etc., represents a major evolution in road safety. In the automotive sector, the term vehicle active safety systems refers to those whose goal is to help avoid a crash or to reduce the risk of having an accident. These systems safeguard us, being in continuous evolution ...

In 2010, over 20.3 million vehicles were recalled. Software issues related to automotive controls such as cruise control, anti-lock braking system, traction control and stability control, account for an increasingly large percentage of the overall vehicles recalled. There is a need for new and scalable methods to evaluate automotive controls in a realistic and open setting. We have developed Au...

Go-karts are popular sport mini-car in western countries, and there are gaining prominence in developing countries such as Nigeria. Its performance is determined by the chassis design and the braking system is its lifeline. Because of the lack of a suspension system and differentials, a good chassis must be able to bend and twist. This Go-kart is powered by a Yamaha Vino Automatic Petrol 2-str...

& Conclusions-The increasingly ubiquitous use of software systems has created the need of being able to depend on them more than before, and of being able to measure just how dependable they are. Knowing that the system is reliable is absolutely necessary for safety/mission-critical systems, where any kind of failure may result in an unacceptable loss of human life. This study models and analyz...

There is perhaps no better symbol of the 21st century than the automobile. It is the dominant means of transport aspired to throughout the world; indeed, many a politician throughout this century has furthered his or her career by promising constituents a greater economic ability to own an automobile. Furthermore, there are more automobiles on the road than any other motorized vehicle. As of 19...
