- The present invention relates to a hybrid transport vehicle which needs an overhead wire and/or a rail for a railway vehicle, street car, monorail, trolley bus, etc. and has plural kinds of energy supply means and/or running drive means.
- Hitherto, in the field of automobiles running on a road, it is proposed, for example in JP 2001-231109 A to add an operation informing means for informing operational conditions to a hybrid vehicle which is provided with an engine which generates driving power by burning fuel and a motor which is driven with an electric power source such as fuel battery, as a running drive means.
- The above-mentioned operation informing means, for example as shown in FIG. 5, is provided with a display displaying images, a hybrid controller, a display-driving circuit, etc. The operation informing means is constructed so that when the hybrid controller requires the display-driving circuit to display images corresponding to engine running modes on the display, the display-driving circuit lights a region Eg expressing an engine, blinks, in a driving power transmitting direction, a region Ds expressing a drive shaft, a region Ax expressing a wheel shaft and regions Wh expressing wheels, and turns off the light of an region expressing a driving motor, a region expressing fuel battery and a region expressing a battery.
- In a hybrid transport vehicle which needs an overhead wire and/or a railway as in a railway vehicle, street car, monorail, trolley bus, etc., and has a plurality of energy supply means such as the overhead wire, battery, fuel battery, engine, generator driven thereby, etc. and at least one driving means for running such as a motor, engine, etc., also, it can be considered to offer information of an energy supply condition (an energy quantity (a quantity of fuel), energy transmitting condition, etc.) and an operation condition of the driving means, and so on to a driver or operator, a maintenance personnel, passengers, and so on. By carrying out such an offer of information, it is possible to conduct properly and easily operation management, vehicle management and maintenance management, and service for passengers is improved.
- However, in the above-mentioned hybrid transport vehicle such as a railway vehicle, etc. there are a lot of items to be considered in order to carry out the above-mentioned information offer, and this case is on a different level from the case of informing a driver of an operation condition in an automobile as mentioned above.
- For example, in a transport vehicle such as a railway vehicle, in some cases, energy is supplied from an overhead wire (pantograph) and energy is returned or recovered to the overhead wire to use it again. Further, in some cases, the transport vehicle runs or travels mutually on a non-electrified route having no overhead wire and an electrified route provided with an overhead wire.
- Further, in the transport vehicle such as a railway vehicle, in many cases, a traction vehicle having driving means arranged therein is coupled to a towed vehicle or vehicles to run. Further, in some cases, a plurality of traction vehicles and a prescribed number of towed vehicles compose a composition vehicle by coupling them in a prescribed order, and a composition operation is effected. In this case, it is necessary to offer information equivalent to that offered to passengers in the traction vehicle to passengers in the towed vehicle, and it is possible to give a great satisfaction to the passengers by offering information of the vehicle composition and individual information of the vehicle that a passenger himself is on board.
- Additionally, since for the transport vehicle such as railway vehicle, a travelling or running route is clear, it is possible to offer positional information for the running route of the vehicle, and it is possible to offer new advantageous information (such as a distance to the destination, required time therefor, etc.), based on the positional information.
- Further, since an overhead wire for railway has a high voltage from several hundreds volts to several thousands volts, a particular consideration about insulation between a power supply line and a signal line, etc. is required as compared with automobiles.
- The present invention is made in view of the above-mentioned matters, and an object of the invention is to provide a hybrid transport vehicle which needs an overhead wire and/or a railway as in a railway vehicle, street car, monorail, trolley bus, etc., and is made so as to be able to offer information of energy supply condition and operation condition of driving means to a driver, maintenance personnel, passengers, etc., to conduct properly and easily running management, vehicle management, maintenance management, etc. and to improve service to the passenger.
- In order to attain the above object, a hybrid transport vehicle according to the present invention needs an overhead wire and/or a railway and has a plurality of kinds of energy supply means and/or driving means. More concretely, the hybrid transport vehicle is made so as to run on a prescribed railway, has a plurality of energy supply means such as an overhead wire, battery, fuel battery, engine, generator driven thereby and further has at least one of driving means for running such as motor, engine, etc. The hybrid transport vehicle comprises a condition detection means for detecting an energy supply condition of the energy supply means and/or an operation condition of the driving means, and an informing means for informing the energy supply condition and/or the operation condition, detected by the condition detection means.
- In a preferable mode, the hybrid transport vehicle is provided with at least one of energy recovery means such as an overhead wire, electricity storing means (storage means), flywheel, etc., and the above-mentioned informing means is made so as to inform further an energy recovery condition by the energy recovery means.
- The above-mentioned informing means, preferably, is provided with a display means such a display. In a more preferable mode, the hybrid transport vehicle comprises a towed vehicle towed by a traction vehicle on which the above-mentioned driving means is arranged. The informing means are arranged on both of the traction vehicle and the towed vehicle.
- The above-mentioned condition detection means, preferably, is made so as to detect further a composition condition of the traction vehicle and towed vehicle, and the above-mentioned informing means is made so as to inform further the composition condition detected by the condition detection means.
- In another preferable mode, the hybrid transport vehicle comprises further information memory means in which operation route information of the hybrid transport vehicle is memorized or means for obtaining the operation route information, the condition detection means detects a running position of the hybrid transport vehicle on the basis of information from the information memory means or the means for obtaining the operation route information, and the informing means informs the position information of the operation route of the hybrid transport vehicle, based on the detected running position.
- In this manner, in the hybrid transport vehicle according to the present invention, various kinds of information such as energy supply condition, etc. is informed to a driver, maintenance personnel, passengers, etc., so that it is possible to know always when necessary whether or not the vehicle is normally operated, whether or not energy is properly recovered without unnecessary consumption of energy, or where the vehicle runs.

- A first embodiment of a hybrid transport vehicle of the present invention will be described in detail hereunder, referring to FIG. 1.
- In FIG. 1 showing the first embodiment of the hybrid transport vehicle according to the present invention, a
hybrid transport vehicle 10 which comprises atraction vehicle 101 is a railway vehicle running on a railway. Thehybrid transport vehicle 10 is constructed so as to be able to run on an electrified way and non-electrified way, and provided with angenerator 103 driven by anengine 102, anoverhead wire 100 and abattery 111, as an energy source. The ac power generated by thegenerator 103 is converted into dc power by aconverter 104 and the converted dc power is supplied to aninverter 107. Power from theoverhead wire 100 is supplied to theinverter 107 via apantograph 105, and power from thebattery 111 is also supplied to theinverter 107. Theinverter 107 drives amotor 108 which is a running-drive means. Rotation-driving power of themotor 108 is transmitted to adriving wheels 110 via a change gear orspeed changer 109, whereby thetraction vehicle 101 runs on therailway 99. - The
hybrid transport vehicle 10 is further provided with a condition detection means 112 (a controller constituting a main part of the condition detection means) for detecting an energy supply condition (an energy flow, an energy quantity (accumulation capacity), transmitting condition, etc.) of thegenerator 103 as an energy supply means, the overhead wire 100 (the pantograph 105) and thebattery 111, and a display means 113 for informing an operation condition of themotor 108, etc. - The above-mentioned condition detection means112 detects a current value, current direction, power, etc. of the
overhead wire 100 on the basis of an output of a sensor arranged on thepantograph 105. The condition detection means 112 further detects a voltage, current value, current direction, power, etc. of theconverter 104,inverter 107 andbattery 111. Here, sensors for detecting a condition of theconverter 104,inverter 107 andbattery 111 are not illustrated, however, it is possible to arrange these sensors inside the respective devices or inside the condition detection means 112. - Further, the
overhead wire 100 for railway vehicles has a high voltage from several hundred voltages to several thousand voltages. Therefore, it is desirable to use an insulated voltage sensor such as an insulated amplifier, and an insulated current sensor such as a current transducer, thereby to be electrically insulated from the high voltage system, in order to ensure the safety of passengers and occupant crews. In the case where the conditions of theconverter 104,inverter 107 and battery are detected, it is necessary to pay the same attention thereto. - Further, the condition detection means112 is made to detect number of revolutions of the
engine 102 andgenerator 103, number of revolutions of driving wheels 110 (revolution speed of the traction vehicle 101), the charging condition of thebattery 111, etc. - The above-mentioned display means113 is constructed of a display such as a liquid crystal monitor, plasma display, etc., and displays an image as illustrated in FIG. 4. It is possible to jointly use a voice generation device or the like. It also is possible to inform by vibrations, smell, etc.
- Further, the
hybrid transport vehicle 10 is provided with seats for passengers and occupant crews, a driving device, wheels other than thedriving wheels 110, a braking device, etc., other than the illustrated components. - On a non-electrified route, the
hybrid transport vehicle 10 drives to rotate themotor 108 with electric power generated by driving thegenerator 103 by theengine 102, and stops the running of theengine 102 when electric power is not needed at a time of stopping or deceleration of the vehicle and when thebattery 111 is sufficiently charged. - Further, the
hybrid transport vehicle 10 drives themotor 108 with the electric power supplied from thebattery 111 under the condition that the engine is being stopped at the time of starting of the hybrid transport vehicle or around a parking area. Further, when a high torque is required in such a case that the hybrid transport vehicle runs on the upgrade, the hybrid transport vehicle is supplied with power from thegenerator 103 and thebattery 111. - By such operation mode change, needless idling operation of the
engine 102 becomes unnecessary, and it becomes possible to run theengine 102 in a region of high fuel consumption efficiency. Thereby, fuel consumption efficiency and energy efficiency are improved and occurrence of environmental pollutant such as carbon dioxides, nitrogen oxides is suppressed. Further, noises are reduced by stopping theengine 102 around a parking area. - On the other hand, on an electrified route installed with the
overhead wire 100, thehybrid transport vehicle 10 is supplied with electric power from the overhead wire via thepantograph 105, and operates themotor 108 to drive thedriving wheels 110. At this time, theengine 102 is stopping, whereby clean electric power from the overhead wire is used. - Here, various operation mode change, that is, operation change of respective constituent elements is done in a total control apparatus which totally controls those constituents. Further, change of energy flow is done by switching devices provided for respective constituents. Further, the change is possible by an operation of each constituent itself, for example, an up and down operation of the
pantograph 105, an on-off operation of theengine 102, etc. - In this manner, by providing a plurality of energy supplying means, it is possible for the vehicle to run both on the electrified route and non-electrified route, and it is possible to jointly use the vehicle for routes.
- Here, the energy supply means is made hybrid, however, it also is possible to construct driving means to be hybrid, that is, to construct both the motor and the engine as driving means.
- Further, as the energy supply means, it is possible to use an accumulator such as a fuel battery, flywheel, ultra-capacitor, lithium secondary battery , nickel hydrogen battery , etc. other than the
overhead wire 100,engine 102 or generator driven thereby, andbattery 111. - Furthermore, it is possible to construct the
motor 108 to be a motor-generator having an enforced power generation function, to provide theinverter 107 with a converter function, and to construct thebattery 111 andoverhead wire 100 as an energy recovery means. In this case, during deceleration, the kinetic energy of the vehicle is recovered to thebattery 111 via themotor 108 andinverter 107, or to theoverhead wire 100 via thepantograph 105. - As for energy recovering means, it also is possible to use the accumulator such as a flywheel, ultra-capacitor, lithium secondary battery, nickel hydrogen battery , etc. other than the
battery 111 andoverhead wire 100. - Here, in the
hybrid transport vehicle 10 in which the energy supply condition of the plurality of energy supply means (100, 103, 111) and the operation condition of each constituent such as themotor 108, etc change, information of the energy supply condition and operation condition is important. - Here, the condition detection means112 detects the above-mentioned energy supply and recovery condition and the operation condition, and the display means 113 displays visually the energy flow and operation conditions of the respective constituents as illustrated in FIG. 4, which is described in detail later.
