20100212984 | AUTOMATIC TRANSFER APPARATUS - In an automatic transfer apparatus, a carriage tractor and a carriage are respectively equipped with connecting portions and through which the carriage tractor is connected near the substantial center of the bottom of the carriage. The automatic transfer apparatus is provided with displacement restricting means for restricting lateral displacement of the carriage tractor or the carriage with respect to the running direction thereof when the carriage tractor runs in the traverse direction while towing the carriage. Therefore, the carriage tractor is capable of running in the forward-reverse direction and the traverse direction while simplifying and downsizing the structure of the carriage tractor. | 08-26-2010 |
20100308769 | METHOD AND SYSTEM FOR MANAGING CHARGE OF AUTOMATED GUIDED VEHICLE - While construction is easily applied to a line, a main route and a charge route can always be managed so as to accommodate a fixed number of vehicles without delaying conveyance along the main route even if the number of fully-charged AGVs (automated guided vehicles) is large or zero, whereby smooth operation of the line is not hampered. A method for managing charge of a plurality of battery-driven AGVs circulating on the main route provided with an automatic charge station includes: a first step of detecting, using an AGV, a marker for battery voltage check provided on a main route to measure the voltage of a battery of the AGV; a second step of changing the route of the AGV to advance it into a charge route provided in an automatic charge station, stopping the AGV in a charging position, and charging the battery automatically by using an automatic charger, if the measured battery voltage has lowered to a level requiring charging; and a third step of conveying the AGV that has been automatically charged to a standby place provided in the automatic charge station to make the AGV stand by at the standby place, and restoring the AGV with charged battery that is waiting at the standby place back to the main route. | 12-09-2010 |
20110009238 | SELF-PROPELLED VEHICLE FOR CONVEYANCE AND METHOD OF CONTROLLING STOP THEREOF - A self-propelled vehicle for conveyance that can be safely stopped without deviating from a predetermined route when an obstacle is detected during running, and a method of controlling a stop of the self-propelled vehicle for conveyance are provided. The method of controlling the stop of the self-propelled vehicle for conveyance includes a second detection step in which an obstacle located at a set distance is detected during the running of the self-propelled vehicle for conveyance, and a stop step in which a leftward or rightward positional deviation of the self-propelled vehicle for conveyance from the predetermined route is correctively controlled in the state where brake means for a pair of left and right driving wheels are released and the self-propelled vehicle for conveyance is stopped, when the positional deviation turns out to be present on the basis of detection of the obstacle in the second detection step. Therefore, when the obstacle is detected during the running of the self-propelled vehicle for conveyance, the self-propelled vehicle for conveyance is safely stopped without deviating from the predetermined route. | 01-13-2011 |

20090024292 | Vehicle controller and control method - An ECU executes a program including the steps of: detecting an accelerator position based on a signal transmitted from an accelerator position sensor | 01-22-2009 |
20100137103 | SHIFT CONTROL DEVICE AND SHIFT CONTROL METHOD FOR AUTOMATIC TRANSMISSION - An electronic control unit is provided with two types of gear change maps: a first gear change map based on the vehicle speed and the accelerator pedal operation amount; and a second gear change map based on the vehicle speed and the required drive force of the vehicle. The electronic control unit determines whether the automatic transmission should downshift with reference to the first gear change map, and determines whether the automatic transmission should upshift with reference to the second gear change map. | 06-03-2010 |
20100197457 | VEHICLE DRIVING FORCE CONTROL DEVICE - A shift output torque control unit executes a shift output torque control to control an engine torque so as to reduce a driving force difference, which is a variation width of a driving force due to downshift of an automatic transmission. Thus, in comparison with the case in which the shift output torque control is not executed, it is possible to smooth a variation in driving force associated with the downshift. As a result, occupants' comfort and controllability to driving operation may be improved. | 08-05-2010 |
20140200758 | HYBRID VEHICLE - A control device is configured to, during acceleration, set a first operation point on a basis of an engine output power and a high torque constraint, set a second operation point on a basis of the engine output power and a high efficiency constraint, set a target operation point so that a target rotation speed of the engine is varied from a first operation rotation speed toward a second operation rotation speed and the engine output power is output from the engine, set a third operation point on a basis of a travel required power and the high efficiency constraint after that, and vary the target rotation speed from the second operation rotation speed toward a third operation rotation speed and set the target operation point so that the engine is operated at the target operation point to operate the engine in accordance with the high efficiency constraint. | 07-17-2014 |
