“…One of disadvantage of the fuzzy controller is its instability response, and the fluctuation to the normal force is the result from this instability. However, using this controller leads to a noticeable increase of the braking force and the stopping distance before the crash [3,12]. This also causes a reduction of the deformation of the front-end structure after the crash.…”

“…In addition, the ABS helps reducing the stopping distance of a vehicle compared with the conventional braking system. The active suspension control system (ASC) is used to improve the quality of the vehicle ride and reduce the vertical acceleration [2,3]. On the other hand, nowadays, Occupant safety becomes one of the most important research areas and the automotive industry increased their efforts for enhancing the safety of the vehicles.…”

This paper focuses on the use of vehicle dynamics control systems (VDCS) to mitigate vehicle collisions in case of offset frontal vehicle-to-vehicle crash scenario. A unique 6-degree-of-freedom vehicle dynamics/crash mathematical model is developed and analyzed in this research. The model is used to define the vehicle body crash parameters by integrating a vehicle dynamics model with a vehicle front-end structure model. In this model, the anti-lock braking system and the active suspension control system are co-simulated with the full car vehicle dynamics model and integrated with the front-end structure. The associated equations of motion of the model are developed and solved numerically. Four different cases of VDCS are investigated in this paper and their associated results are compared with the free rolling case scenario. It is shown from the numerical simulations that the vehicle dynamics/crash response can be captured and analyzed quickly and accurately. Furthermore, it is shown that the VDCS affect the crash characteristics positively.

“…In particular, one of the first relevant studies [10] has investigated the ABS and the suspension equipped with electro-hydraulic actuators. The simulation of the car braking from 16 m/s on the wet asphalt demonstrated for the quarter vehicle model that the stopping distance is reduced by 7-8% with the integrated control as compared with the conventional ABS operation.…”

This paper gives an extended analysis of automotive control systems as components of the integrated motion control (IMC). The cooperation of various chassis and powertrain systems is discussed from a viewpoint of improvement of vehicle performance in relation to longitudinal, lateral, and vertical motion dynamics. The classification of IMC systems is proposed. Particular attention is placed on the architecture and methods of subsystems integration.

This paper has presented a control system for vehicle dynamics and mass estimation. The objective of this paper is to use a single-tyre model of slip control integrated with extended Kalman filter (EKF) to estimate the states of a vehicle such as the forward velocity, wheel slip, coefficient of friction of the road surface and the mass that cannot be measured directly. In order to do this, the dynamics of a vehicle moving with a forward velocity were obtained using a single-tyre model. The dynamic equations in continuous time were transformed into their equivalent discrete time form. A two degree of freedom proportional integral and derivative (2DOFPID) control algorithm was implemented for the control loop. An estimator was designed using the extended Kalman filter algorithm to carry out the estimation based on noisy measurement of wheel rotational speed. The entire system was modeled using Matlab/Simulink blocks. Simulations were performed to determine the effectiveness of the estimator. The simulation results showed that the extended Kalman filter effectively estimated the states of a single-tyre model of a vehicle represented by a slip control system. Though the results obtained seemed promising but will be improved if the covariance matrices are calculated with adequate information and are better tuned.
