This paper introduces a case study on the potential of new mechatronic chassis systems for battery electric vehicles, in this brake-by-wire (BBW) system and in-wheel propulsion rear axle combined with an integrated control providing common safety features like anti-lock braking (ABS), enhanced functionalities, torque blending. The presented controller was intended to also show continuous strate...

Anti-lock braking system (ABS) is considered an essential safety in electric vehicles that works to grant a reliable vehicle driving experience, and it very important ensure the security of such onboard system. This work presents detailed analysis associated with comparison includes several techniques based on pattern recognition for biasing fault detection wheel speed sensors. These are K-near...

The worst case execution time (WCET) of a task is a key component in the design and development of hard real-time systems. Malfunctional real-time systems could cause an aeroplane to crash or the anti-lock braking system in a car to stop working. Static WCET analysis is a method to derive WCET estimates of programs. Such analysis obtains a WCET estimate without executing the program, instead re...

A ZigBee based collision avoidance system for railways has been proposed in this paper. The Train Anti-Collision System (TACS) has four sub centers namely, Train Subsystem, Station/Control Center Subsystem, Signalling Post Subsystem and Level Crossing Subsystem. A safe distance of 1 Km has been given for braking between the trains in case of collision distance. Based on the studies, it has been...

by Kshamta Jerath, M.S. Washington State University August 2002 Chair: Frederick T. Sheldon 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-critical systems, where any kind of failure may resu...

The purpose of this study is to understand the nonlinear dynamics of longitudinal ground vehicle traction. Specifically, single-wheel models of rubber-tired automobiles under straight-ahead braking and acceleration conditions are investigated in detail. Customarily, the forward vehicle speed and the rotational rate of the tire/wheel are taken as dynamic states. This paper motivates an alternati...

In the past four Years, Road Traffic Injuries (RTI) ranked fourth among the leading cause of death. Nearly 1.3 million people die every year on the world’s roads and 20 to 50 million people suffer non-fatal injuries, with many sustaining a disability as a result of their injury. However, active safety systems like ABS (Anti−lock Braking System) and ESP (Electronic Stability Program) offer possi...

Automatic generation of correct software from requirements has long been a “holy grail” for system and software development. According to this vision, instead of implementing a system and then working hard to apply testing and verification methods to prove system correctness, a system is rather built correctly by construction. This problem, referred to as synthesis, is undecidable in the genera...

A torque converter, which is a hydrodynamic clutch in automatic transmissions, transmits power from the engine shaft to the transmission shaft either by dynamically multiplying the engine torque or by rigidly coupling the engine and transmission shafts. The torque converter is a critical element in the automatic driveline, and it affects the vehicle’s fuel consumption and longitudinal dynamics....
