In this study, a new FlexRay vehicle communication network was integrated with the current mainstream network CAN. The FlexRay network was connected by a hybrid topology to a brake-bywire node to implement an x-by-wire control system. The CarSim software was combined with LabVIEW and interface cards to construct and test the active safety of a simulated car. An anti-lock braking system (ABS) no...

According to the independence, accuracy and controllability of the driving/braking torque of the distributed drive electric vehicle, a control strategy of differential drive assisted steering was designed. Firstly, the assisted curve under different speed and steering wheel torque was developed and the differential torques were distributed to the right and left front wheels. Then the steering r...

In this report, we consider a passivation method that uses an input-output transformation matrix. This matrix generalizes the commonly used methods of series, feedback and parallel (or feedforward) interconnections to passivate a system. Through an appropriate design of this matrix, positive passivity levels can be guaranteed for the system. The passivation parameters can be selected by solving...

The vehicle model was built based on MATLAB/Simulink and Carsim, the multi-objective active collision avoidance control algorithm considering safety comfort established a predictive (MPC) algorithm. system for studied by simulation experimentation. results show that an MPC can follow under different working conditions ensure in process of following while meeting requirements system.

In view of the severe weather conditions in cold regions, basic characteristics and braking distance ice snow covered pavement are analyzed. This paper uses PreScan/CarSim/Simulink software co-simulation method to test automatic emergency (AEB) system on ice-snow roads. Through appropriate adjustment time collision (TTC) threshold, car makes road with low friction coefficient can achieve effect...

Vehicle active safety control is attracting ever increasing attention in the attempt to improve the stability and the maneuverability of electric vehicles. In this paper, a neural network combined inverse (NNCI) controller is proposed, incorporating the merits of left-inversion and right-inversion. As the left-inversion soft-sensor can estimate the sideslip angle, while the right-inversion is u...

Road traffic statistics have shown that multi-event crashes typically result in a higher death toll than single-event crashes. One type of those multi-event crashes could be a crash where the initial harmful event leads to a loss of directional control of the vehicle. In this work, we study countermeasures during such crashes, namely, vehicle stabilization in response to exogenous impulsive dis...

Moving car on rough road suddenly gets out of its way for some reason and moves to the edge of the road at the same speed. Since the most important factor in car overturning is vertical acceleration in the wheels and car speed and road conditions determine the vertical instantaneous acceleration, brake system according to change of the spring length is designed in such a way that by monitoring ...
