In the automotive domain, several loosely-coupled Architecture Description Languages (ADLs) compete to provide a set of abstract modeling and analysis services on top of the implementation code. In an effort to make all these languages, and more importantly their underlying models, interoperable, we use the UML Profile for MARTE as a pivot to define the semantics of these models. In this paper,...

"The anti-lock braking system is a safety equipment that prevents the vehicle wheels from locking up under emergency, panic, or harsh conditions, ensuring steering control during and reducing distance. This studied by automotive engineers for performance comparisons determining optimal methods. For this reason, paper presents method to mathematically model system. The obtained afterwards used i...

Dongsheng Wu, Jun Li, Xiaoping Shu, Xiaojing Zha, Beili Xu School of Mechanical and Electronic Engineering, East China Jiaotong University,Nanchang 330013, P. R. China Abstract: Braking performance test methods are compared and analyzed .ABS will not work if the speed is too low when the automobile is tested by tester and load testing. Since the braking performance can not be evaluated accurate...

Antilock braking system (ABS) is a highly nonlinear system including variation and uncertainties in the parameters due to changes in vehicle loadings, road condition, etc. It is a difficult task to design an ideal controller for ABS. In this paper, a novel robust controller named fractional order sliding mode controller (FOSMC) is proposed for ABS to regulate the slip to a desired value. The pr...

This paper focuses on the development of a robust fuzzy sliding-mode scheme for controlling a vehicle motion system by continuously adjusting the brake torque, Fuzzy logic known for its properties of universal approximator and sliding mode control for its robustness in the presence of parameter variations and the disturbances are employed to control the wheel slip rate in emergency braking mane...

This paper proposes an innovative way to interface the concept of FUZZY LOGIC and ABS system used (mainly in transportation and motors) and tests on an experimental car with antilock-braking system (ABS) and vehicle speed estimation using fuzzy logic. Vehicle dynamics and braking systems are complex and behave strongly non-linear which causes difficulties in developing a classical controller fo...

This work exposes a largely unexplored vector of physical-layer attacks with demonstrated consequences in automobiles. By modifying the physical environment around analog sensors such as Antilock Braking Systems (ABS), we exploit weaknesses in wheel speed sensors so that a malicious attacker can inject arbitrary measurements to the ABS computer which in turn can cause lifethreatening situations...
