In the real traffic situations, vehicle would make a braking as the response to avoid collision with another vehicle or avoid some obstacle like potholes, snow, or pedestrian that crosses the road unexpectedly. However, in some cases the spontaneous-braking may occur even though there are no obstacles in front of the vehicle. In some country, the reckless driving behaviors such as sudden-stop b...

This paper proposes an intelligent regenerative braking control of hybrid buses through a neuro-fuzzy controller (NFC) by combining the fuzzy logic algorithm and the artificial neural networks. The braking torque distribution between the integrating starting generator (ISG) and the friction disc brake is addressed through the proposed NFC. The results of simulation and validation show that the ...

According to the self-excitation doubly salient retarder’s braking torque equation and dynamic equation, its braking torque model and the vehicle’s dynamics model can be built using Matlab/Simulink. The simulation results show that the relationship of automobile braking torque, excitation current and retarder speed, and that the variation of vehicle deceleration rate. This method can optimize t...

In a naturalistic study of teenage drivers (N = 42) hard braking events of ≤-0.45 g were assessed over the first 6 months of licensure. A total of 1,721 hard braking events were recorded. The video footage of a sample (816) of these events was examined to evaluate validity and reasons for hard braking. Of these, 788 (96.6%) were estimated valid, of which 79.1% were due to driver misjudgment, 10...

This paper presents results from a series of evolutionary robotics simulations that were designed to investigate the informational basis of visually-guided braking. Evolutionary robotics techniques were used to develop models of visuallyguided braking behavior in humans to aid in resolving existing questions in the literature. Based on a well-used experimental paradigm from psychology, model ag...

It is desirable for driving support systems to improve the safety of driver vehicle systems, and at the same time to have a performance that does not make individual drivers feel uncomfortable. Since human beings have various control characteristics, any system that supports driving under fixed conditions without taking such characteristics into consideration cannot be a driving support system ...

In this paper, an antilock–antiskid braking system controller, which has been designed for stability enhancement of vehicles during braking and turning, is presented. Using available signals, a novel structure is proposed for vehicle stability improvement for critical driving conditions such as braking on slippery or μ-split road surfaces. In conventional vehicles, undesired lane changes may oc...

In the present paper, the idea of braking energy regeneration and reusing that energy during acceleration for a refuse truck is comprehended. According to their driving cycle, the refuse trucks have a good potential for braking energy regeneration. On the other hand, hydraulic hybrid is a powertrain with high power density which is appropriate for energy regeneration. In the primary stage of th...

Train braking is a very complex process, specific to rail vehicles and of great importance by the essential contribution on the safety of the traffic. This complexity results from the fact that during braking occur numerous phenomena of different kinds mechanical, thermal, pneumatic, electrical, etc. The actions of these processes take place in various points of the vehicles and act on differen...
