| PROBLEM TO BE SOLVED: To always obtain an optimum steering characteristic according to the change of vehicle speed and the change of a steering wheel steering angle in a vehicle of such constitution as to steer by changing the rotating speed of lateral travel driving wheels in addition to steering steered wheels. SOLUTION: Lateral travel driving wheels Wr independently driven being respectively connected to a pair of continuously variable transmissions are increased/reduced in speed at the same rotating speed by the operation of a change lever 10 so as to move a vehicle forward and backward, and when the steering angle of a steering wheel 8 exceeds the specified value, the turning inside travel driving wheel speed is reduced, and the turning outside travel driving wheel speed is increased to turn the vehicle. When the steering wheel steering angle becomes the specified value or more during low speed forward travel, the turning inside travel driving wheel stops to make a pivotal turn, but during high speed forward travel and backward travel, a pivotal turn is not made even if the steering wheel steering angle becomes the specified value or more. | ||||||

| <P>PROBLEM TO BE SOLVED: To park a vehicle by a small parking labor even if a parking space is narrow for the vehicle having at least two steering wheels and at least two driving wheels which are driven independently to each other. <P>SOLUTION: A vehicle 1 has at least two driving wheels 11 which are driven independently to each other in order to ease a parking process to a parking space 3 for tandem parking. As a driving mechanism, for example, hub motors 13 are used. Here, the driving wheels 11 are two opposite wheels, that is, the wheels which are attached to both sides of a shaft. When the driving wheels 11 run in curves, one driving wheel 11 runs in an inner curve and the other driving wheel 11 runs in an outer curve. In order to ease the curve running and the steering running of the vehicle 1, the vehicle 1 has further at least two steering wheels. In this embodiment, the steering wheels are the ones attached to a steering shaft 15. By varying the direction of the steerable wheel 17 properly by the steering shaft 15, the wheels are moved, and the steering process or the rotating running of the vehicle is started. <P>COPYRIGHT: (C)2011,JPO&INPIT | ||||||
