20110087395 | POWER SUPPLY SYSTEM FOR ELECTRICALLY POWERED VEHICLE, AND METHOD FOR CONTROLLING THE SAME - A power supply system includes a main power storage device and a plurality of sub power storage devices. A converter is connected to selected one of the sub power storage devices to convert voltage between the selected sub power storage device and an electric power feeding line bidirectionally. When a request for switching the selected sub power storage device in use is generated, upper limits on electric power input/output to/from the selected sub power storage device are continuously varied. Thus, discontinuous variation of electric power input/output to/from the power supply system during the process for switching the selected sub power storage device can be avoided. Consequently, sudden change in a behavior of an electrically powered vehicle can be avoided. | 04-14-2011 |
20110251745 | POWER SUPPLY SYSTEM FOR ELECTRICALLY POWERED VEHICLE, ELECTRICALLY POWERED VEHICLE, AND METHOD FOR CONTROLLING THE SAME - A power supply system includes a main power storage device and a plurality of sub power storage devices. A converter is connected to selected one of the sub power storage devices to convert voltage between the selected sub power storage device and an electric power feeding line bidirectionally. When the travel mode of an electrically powered vehicle is an EV mode, switching processing of a sub power storage device is performed based on the selected sub power storage device's SOC. On the other hand, when the travel mode of the electrically powered vehicle is an HV mode, control under which the SOC of the main power storage device and the plurality of sub power storage devices as a whole is kept constant is carried out, and switching of the selected sub power storage device is prohibited. | 10-13-2011 |
20110257825 | POWER SUPPLY SYSTEM FOR ELECTRICALLY POWERED VEHICLE AND METHOD FOR CONTROLLING THE SAME - A power supply system includes a main power storage device and a plurality of sub power storage devices. A converter is connected to selected one of the sub power storage devices to convert voltage between the selected sub power storage device and an electric power feeding line bidirectionally. In the case of a switching-forced region where the SOC of the selected sub power storage device in use is lower than a lower limit reference value, the sub power storage device is forced to be switched regardless of the vehicle's state. In contrast, in the case of a switching-permitted region where the SOC is higher than that in the switching-forced region, a switch request is generated based on the vehicle's state under the condition that does not influence the vehicle's drivability. | 10-20-2011 |

20150080176 | INDUSTRIAL VEHICLE - An industrial vehicle includes an accelerator, an accelerator opening sensor which detects an opening of the accelerator, a loading unit, an engine and a torque restriction releasing unit. When the torque restriction releasing unit is set in an Eco-mode in which torque of the engine is restricted, if the opening of the accelerator detected by the accelerator opening sensor is a first predetermined value or greater and at least one of conditions that a speed of the vehicle is a second predetermined value or greater and that the loading unit is in a lifting operation, is satisfied and such conditions of the accelerator and the vehicle speed and/or lifting operation are continued for a predetermined period of time, the torque restriction releasing unit releases the torque restriction. | 03-19-2015 |
20150081191 | VEHICLE SPEED CONTROL APPARATUS OF INDUSTRIAL VEHICLE - A vehicle speed control apparatus of an industrial vehicle has a controller that determines a target engine speed by PI control based on a deviation between a target vehicle speed and an actual vehicle speed. The controller controls an upper limit of the target engine speed according to an actual engine speed. | 03-19-2015 |
20150094936 | INDUSTRIAL VEHICLE - An industrial vehicle which is equipped with an engine and having an Eco-mode in which torque of the engine is restricted includes an accelerator, an accelerator opening detector that detects an opening of the accelerator, a vehicle speed detector that detects a speed of the vehicle, an engine speed detector that detects a speed of the engine, and a torque restriction releasing unit which, when the torque of the engine is restricted, if conditions that the opening of the accelerator detected by the accelerator opening detector is a first predetermined value or greater, that the vehicle speed detected by the vehicle speed detector is a second predetermined value or smaller and that the engine speed detected by the engine speed detector is a third predetermined value or smaller are satisfied, releases the torque restriction. | 04-02-2015 |
20150275798 | VEHICLE EQUIPPED WITH A HYDRAULICALLY-OPERATED DEVICE - A vehicle equipped with a hydraulically-operated device includes an engine that drives the hydraulically-operated device, a temperature detection unit that detects a temperature of the engine or hydraulic oil and a control unit that controls the engine. The control unit is allowed to control torque of the engine in accordance with a predetermined specified torque limit value when the control unit is in an Eco-mode, and does not control the torque of the engine in accordance with the specified torque limit value in the Eco-mode when the temperature detected by the temperature detection unit is a predetermined specified release temperature or lower. The release temperature is set as a temperature at which output of the engine is hard to be stabilized. | 10-01-2015 |
20150275799 | INDUSTRIAL VEHICLE - An industrial vehicle has an engine, a drive wheel, and a power transmission mechanism that transmits power of the engine to the drive wheel wherein the power transmitted through the power transmission mechanism causes creeping of the vehicle. The industrial vehicle includes a control unit that controls an engine speed of the engine and a vehicle speed detection unit that detects a vehicle speed of the vehicle. The control unit controls the engine speed at a first engine speed when the vehicle is in a non-traveling state, and when the vehicle speed has exceeded a predetermined vehicle speed, the control unit controls the engine speed at a second engine speed that is lower than the first engine speed, and the second engine speed is set to generate a desired creeping speed. | 10-01-2015 |
