The goal of our research is to develop a practicable vehicle for the lower limbs disabled along with improving health, which can be used in their daily life. We developed a vehicle based on a wheelchair, we call it as cycling chair. The cycling chair has two relatively big front wheels linked to the pedals with a mechanical chain to propel it, and a steering wheel at the rear part is controlled...

This paper presents the architecture of a software system able to assess the cognitive effort of a driver by monitoring the interaction between the driver and the steering wheel; this system is called WL Manager (WLM). The advantage of a Workload Manager System based on the steering dynamic is that of being not invasive in comparison to other workload measures, in particular physiological (hear...

Injuries unique to pregnant occupants involved in motor-vehicle crashes include placental abruption, uterine rupture or laceration, and direct fetal injury. The mechanisms and characteristics of these injuries are discussed using examples from a literature review and from recent investigations of crashes involving pregnant occupants. In addition, a review of the relationship between the pregnan...

[Abstract] An automated E/H steering controller is essential for autonomous off-road equipment. This paper presents a methodology for designing the E/H steering controller through a combination of testing and simulation. The steering kinematic model provides the steering linkage gain between the hydraulic actuator and the front wheel. The model makes it possible to close the steering control lo...

Various forms of electronic stability, traction and launch control have existed for over two decades, improving safety, sports performance and off-road capabilities of vehicles. These technologies involve individual control of each wheel’s drive torque or braking force in response to the dynamics of the driving conditions and the driver’s intentions. With the exception of launch control, applic...

Abstract: Robust decoupling of the lateral and yaw motions of a car has been achieved by feedback of the integrated yaw rate into front wheel steering. In the present paper the yaw disturbance attenuation is analyzed for a generic single-track vehicle model. The frequency limit, up to which yaw disturbances are attenuated, is calculated. For specific vehicle data, it is shown that this control ...

To determine the (k, l)-radius of a graph we have to find a set L of l vertices, such that the maximum k-distance of a set K, where |K| = k and L ⊆ K, attains the minimum value in a graph. This notion generalizes the radius, diameter and k-diameter. In this contribution the (k, l)-radius of the wheel Wn is determined for all possible values of parameters k and l.

Abstract Vehicle braking stability performance can improve the safety of vehicle driving during a braking. However, some parameters structure impact on stability, characteristic law relevant is ignored. A simulation model established using software CarSim. The included in system, suspension, steering mechanism, system. wheelbase, and height centre mass analysed. concluded. Based law, ideal obta...

Vehicle handling and control is an essential aspect of intelligent driver assistance systems, a building block of the upcoming generation of ”smart cars”. A car’s handling is affected by (i) technological (engine, suspension, brakes, tires, wheels, steering, etc.), (ii) environmental (road condition, weather, traffic, etc.), and (iii) human (attentiveness, reactiveness, driver agility, etc.) fa...
