MATLAB, Simulink, and Simscape are market-leading products in Model-Based Design (MBD). Applying acausal causal modeling methods to model the physical plant control algorithms of mechatronic systems results high-fidelity virtual prototype models that can be used for Model-in-Loop (MiL) development. In this paper, an electric-driven vehicle is modeled, which execute various driving cycle inputs....

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 practical problems that usually come up during the on-vehicle testing of motor car shock absorbers have been discussed. Results example tests carried out to EUSAMA standard procedure were compared test results obtained with using newer methods, i.e. phase angle method and half power bandwidth (HPBM). issue incompatibility typical excitation applied by diagnostic suspension testers one often...

Squeal is an example of noise caused by vibrations induced by friction forces that lead to dynamic instability of the brake system. Several experimental, theoretical and numerical works have been carried out over the last six decades. Certain of these works have focused on simplified brake systems and identified ‘lock-in’ instability as being the cause of squeal. This paper presents a short bib...

Accurate knowledge on the absolute or true speed of a vehicle, if and when available, can be used to enhance advanced vehicle dynamics control systems such as anti-lock brake systems (ABS) and auto-traction systems (ATS) control schemes. Current conventional method uses wheel speed measurements to estimate the speed of the vehicle. As a result, indication of the vehicle speed becomes erroneous ...

Hybrid electric vehicles employ a hydraulic braking system and a regenerative braking system together to provide enhanced braking performance and energy regeneration. In this paper an integrated braking system is proposed for an electric hybrid vehicle that include a hydraulic braking system and a regenerative braking system which is functionally connected to an electric traction motor. In the ...

Axiomatic design is applied to design of real-time control software. As a case study of software design for on-board computers of automobiles, the software of the current anti-lock braking system (ABS) is analyzed based on axiomatic design. It is shown that the current design is a coupled design and that it can be decoupled to improve the performance of the anti-lock braking system software. In...

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...

Concurrent designs can be automatically verified by transforming them into an automata-based representation and by model checking the resulting model. However, when transforming a concurrent design into an automata-based representation, each method has to be translated into a single automaton. This produces a significant overhead for model checking. In this paper, we present an optimization of ...
