Overtaking is one of the common actions that the driver performs while travelling on the road. Without enough information about the road, overtaking is dangerous and causes many accidents. Although overtaking is important, little research was done in this area. Especially,
An automotive Virtual Side View Mirror (VSVM), which uses a closed-circuit video system to generate images of the sides of a vehicle and present the images to the driver in a manner to improve traffic “situational awareness.” Benefits include: improved safety, reduced noise/vibration, reduced fuel consumption,
1- THE PROBLEM
Amongst the reasons underlying trains’ disasters, two are especially striking: (A) derailment, (B) trains’ crashes either due to derailed carriages, frontal shock or, paradoxically, to ‘backwards’ shocks.
Possible causes for derailment (excess of velocity, some objects on the rails, etc.) are here discarded. Rather,
Hybrid gas-electric vehicles require the addition of electric motors to provide power to the wheels when the vehicles are moved on battery electric energy.
Electric motors for hybrid vehicles are becoming very small and efficient, Nevertheless,
Winding The Spring By Reverse Pedaling (During Static & Dynamic) And Use The Same Energy For Forward Movement
Forward bicycle pedaling only transfers the torque to the wheel. Reverse pedaling doesn’t transfer the torque to the wheel, due to free wheel. So forward pedaling only requires pedal effort and it will vary depends upon load and vehicle type (bicycle, tricycle & handicapped cycle).
We are developing an adaptable human-electric trike that fits into our vision of cities of the near-future. Yax is an efficient vehicle for getting through urban traffic and carrying loads beyond a bicycle's capability. It also goes in spaces where trucks and vans can't go.
