In this paper we present a sliding mode based vehicle control strategy, which includes anti-lock braking and anti-spin acceleration. This strategy uses the slip velocity as controlled variable instead of wheel slip. The sliding mode control is integrated with an adaptation process for the unknown and varying adhesion coefcient of the tire/road interface. The proposed control method is veried ...
SystemC is widely used in hardware/software codesign. Although it is also used for the design of safety-critical applications, existing formal verification techniques for SystemC are still hardly used in industrial practice. The main reasons for this are scalability issues, the lacking support for many practically relevant SystemC language constructs, and that counter-examples are not always ea...
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 ...
Structured models of systems allow us to determine their reliability, yet there are numerous challenges that need to be overcome to obtain meaningful results. This paper reports the results and approach used to model and analyze the Anti-lock Braking System of a passenger vehicle using Stochastic Petri Nets. Special emphasis is laid on modeling extra-functional characteristics like coincident f...
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....
In this paper, an observer-based direct adaptive fuzzy-neural controller (ODAFNC) for an anti-lock braking system (ABS) is developed under the constraint that only the system output, i.e., the wheel slip ratio, is measurable. The main control strategy is to force the wheel slip ratio to well track the optimal value, which may vary with the environment. The observer-based output feedback control...
We present requirements and success criteria for the realworld problem of (off-board) diagnosis of the hydraulic circuit of an anti-lock braking system. The primary problems to be addressed are quite fundamental: First, it is practically impossible to predict the dynamic behavior of this controlled automotive system as it depends on a number of unknown context conditions. Second, there are no d...
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...
