“…Simultaneously, ride comfort is impacted by different variables, for instance, vibration, sound, temperature, visual stimuli, and vehicle assembly plan. An incredible number of examination studies have been directed to further developing ride comfort, especially in the field concerning ride awkward inclination brought about by vertical vibration, and a lot of dynamic and latent suspension control calculations were advanced to further develop the vertical vibration [1,2]. Notwithstanding, the inconvenience feeling isn't just gotten from the vertical vibration, however, it is additionally brought about by measure of vehicle speed increase and jerk in the longitudinal direction, which is how much change in vehicle speed increases [3][4][5].…”

The braking quality is considered the main execution of the adaptive control framework that impacts the vehicle safety and rides solace astoundingly notably the stopping distance. This research work aims to create a pattern and design of an electromechanically adjusted lever that multiplies the applied braking force depending on the inputs given by the sensors to reduce the stopping distance of the vehicle. It is carried out using two main parts of the two-wheeler vehicle: the first part deals with the detection of load acting on the vehicle and identifying the required braking force to be applied, and the second part deals with the microcontroller which activates the stepper motor for varying the mechanical leverage ratio from various loads on the vehicle using two actively movable wedges. The electromechanically operated variable braking force system is developed to actuate the braking system based on the load on the motorcycle. The MATLAB simulation and experimental work are carried out for various loading (driver and pillion) conditions on a two-wheeler. The results indicate that the proposed electronically operated braking system is more effective than the conventional braking system for various loads and vehicle speeds. Specifically, the stopping distance of the vehicle is decreased significantly by about 4.9% between the conventional braking system and the simulated proposed system. Further, the experimental results show that the stopping distance is condensed by about 4.1%. The validation between simulated and experimental results revealed a great deal with the least error percentage of about 0.8%.

For passengers, the most common feeling during running on the bumpy road is continuous vertical discomfort, and when the vehicle is braking, especially the emergency braking, the instantaneous inertia of the vehicle can also cause a strong discomfort of the passengers, so studying the comfort of the vehicle during the braking process is of great significance for improving the performance of the vehicle. This paper presented a complete control scheme for vehicles equipped with the brake-by-wire (BBW) system aiming at ensuring braking comfort. A novel braking intention classification method was proposed based on vehicle braking comfort, which divided braking intention into mild brake, medium comfort brake, and emergency brake. Correspondingly, in order to improve the control accuracy of the vehicle brake system and to best meet the driver’s brake needs, a braking intention recognizer relying on fuzzy logic was established, which used the road condition and the brake pedal voltage and its change rate as input, output real-time driver's braking intention, and braking intensity. An optimal brake force distribution strategy for the vehicle equipped with the BBW system based on slip rate was proposed to determine the relationship between braking intensity and target slip ratio. Combined with the vehicle dynamics model, improved sliding mode controller, and brake force observer, the joint simulation was conducted in Simulink and CarSim. The cosimulation results show that the proposed braking intention classification method, braking intention recognizer, brake force distribution strategy, and sliding mode control can well ensure the braking comfort of the vehicle equipped with the BBW system under the premise of ensuring brake safety.
