VEHICLE AND TRAFFIC SYSTEM
First Claim
1. A vehicle to be occupied and driven by person(s) for travel on road, comprising:
- an electric power collector adapted for receiving and collecting an electric power supplied from overhead line(s) arranged above said road;
a lifting device operable for vertical movement with respect to said overhead line(s) to which said electric power collector is made accessible;
a battery capable of storing said electric power therein;
a drive mechanism for causing movement of said vehicle;
a power supply/distribution control unit which, responsive to said electric power being supplied from said electric power collector, operates to cause the electric power to supply to one or both of said battery and said drive mechanism, or alternatively operates to cause electric power stored in said battery to supply to said drive mechanism, responsive to no electric power supplied from the electric power collector; and
a steering wheel sensor for detecting movement of a steering wheel of the vehicle, said steering wheel sensor being workable such that, upon detecting rotation of said steering wheel by an angle exceeding a predetermined angle, the steering wheel sensor outputs one signal for prohibiting contact of said electric power collector with said overhead line(s) and sends said one signal to said lifting device, and that, upon said steering wheel having been rotated reversely from the thus-rotated state back to a normal home position, the steering wheel sensor outputs another signal calling for contact of said electric power collector with said overhead line(s) and sends said another signal to said lifting device.

Abstract
Provided are a vehicle having high degree of operation freedom due to electric power being able to be supplied to the vehicle during its travel and due to the vehicle being able to drive on normal roads, and a traffic system. A large number of overhead lines are arranged over a road. An extendable electric power collector is provided at the rear of the vehicle, and a battery and a drive mechanism are mounted on the vehicle. When the power collector is in contact with an overhead line, electric power supplied from the overhead line is supplied to the battery to charge it and electric power is supplied also to the drive mechanism. When the vehicle travel on a normal road having no such overhead lines, electric power is supplied from the battery to the drive mechanism.

2. A vehicle to be occupied and driven by person(s) for travel on road, comprising:
-
an electric power collector adapted for receiving and collecting an electric power supplied from overhead line(s) arranged at said road; a lifting device operable for vertical movement with respect to the overhead line(s) to which said electric power collector is made accessible; a battery capable of storing said electric power therein; a drive mechanism for causing movement of said vehicle; a power supply/distribution control unit which, responsive to the electric power being supplied from said electric power collector, operates to cause said electric power to supply to one or both of said battery and said drive mechanism, or alternatively operates to cause electric power stored in said battery to supply to said drive mechanism, responsive to no electric power supplied from the electric power collector; and an overhead line detection sensor for detecting presence and absence of said overhead line(s), said overhead line detection sensor being workable such that, upon detecting said overhead line(s), the overhead line detection sensor outputs one signal for calling for contact of said electric power collector with said overhead line(s) and sends said one signal to said lifting device, and that, upon detecting no overhead line, the overhead line detection sensor outputs another signal for prohibiting contact of said electric power collector with said overhead line(s) and sends said another signal to said lifting device.

3. A vehicle to be occupied and driven by person(s) for travel on road, comprising:
-
an electric power collector adapted for receiving and collecting an electric power supplied from overhead line(s) arranged at said road; a lifting device operable for vertical movement with respect to said overhead line(s) to which said electric power collector is accessible; a battery capable of storing said electric power therein; a drive mechanism for causing movement of said vehicle; a power supply/distribution control unit which, responsive to said electric power being supplied from said electric power collector, operates to cause said electric power to supply to one or both of said battery and said drive mechanism, or alternatively operates to cause the electric power stored in said battery to supply to said drive mechanism, responsive to no electric power supplied from the electric power collector; a steering wheel sensor for detecting movement of a steering wheel of the vehicle; an overhead line detection sensor for detecting presence and absence of said overhead line(s); and a lifting control means workable in such a manner that, while said overhead line(s) is/are being detected by said overhead line detection sensor, if said steering wheel sensor detects rotation of said steering wheel by an angle exceeding a predetermined angle, the lifting control means outputs one signal for prohibiting contact of said electric power collector with said overhead line(s) and sends said one signal to said lifting device, and that, upon said steering wheel having been rotated reversely from the thus-rotated state back to a normal home position, the lifting control means outputs another signal calling for contact of said electric power collector with said overhead line(s) and sends said another signal to said lifting device, wherein said lifting control means is also workable such that, if no overhead line is detected by the overhead line detection sensor, the lifting control means positively works to prohibit contact of said electric power collector with said overhead line(s), irrespective of any detection result received from said steering wheel sensor thereto.
