20100070123 | VEHICLE AND CONTROL METHOD THEREOF - In a hybrid vehicle equipped with an engine, a planetary gear mechanism linked to the output shaft of the engine and to a driveshaft, a first motor linked the planetary gear, a second motor inputting and outputting power to and from the driveshaft, and a battery inputting and outputting electric power to and from the motors, when the battery temperature Tb is lower than the preset reference temperature Tbref, drive control prohibits the intermittent operation of the engine and controls the engine and the motors to output the torque demand to the driveshaft with warm-up control of the battery. When the battery temperature Tb is higher than or equal to the preset reference temperature Tbref and the cooling water temperature Tw is higher than or equal to the preset reference temperature Twref, drive control performs the intermittent operation of the engine and controls the engine and the motors to output the torque demand to the driveshaft. When the battery temperature Tb is higher than or equal to the preset reference temperature Tbref and the cooling water temperature Tw is lower than the preset reference temperature Twref, drive control prohibits the operation of the engine and controls the engine and the motors to keep the warm-up control of the battery and to output the torque demand to the driveshaft. | 03-18-2010 |
20100121513 | VEHICLE AND CONTROL METHOD THEREOF - In a hybrid vehicle equipped with an engine, a planetary gear mechanism linked to the output shaft of the engine and to a driveshaft, a first motor linked the planetary gear, a second motor inputting and outputting power to and from the driveshaft, and a battery inputting and outputting electric power to and from the motors, when a cooling water temperature Tw of the engine is lower than a threshold Twref, that is, the intermittent operation of the engine is prohibited, a controller performs a warm-up control on condition that a battery temperature Tb is a preset reference temperature Tα, while performing a low state of charge control on condition that a battery temperature Tb is higher than or equal to a preset reference temperature Tα and lower than a preset reference temperature Tβ. The warm-up control causes the battery to be charged and discharged by compulsion by setting a state of charge of the battery alternately to a low state of charge and to a high state of charge and ensures output of a driving force equivalent to the driving force demand for driving the vehicle within input and output limits of the battery. The low state of charge control causes the battery to be charged and discharged to approach a state of charge of the battery to a preset low state of charge that is lower than a normal state and ensures output of a driving force equivalent to the driving force demand for driving the vehicle within input and output limits of the battery. | 05-13-2010 |
20100152938 | VEHICLE AND CONTROL METHOD OF VEHICLE - When the low SOC control request is output and the catalyst warming request is not output, the low SOC control mode is set as a control mode and the state of charge (SOC) of the battery is controlled according to the managing center SOC* set as the smaller value S | 06-17-2010 |

20100305796 | VEHICLE CONTROL APPARATUS - A control unit of a vehicle control apparatus includes a module for receiving an ON signal from an eco switch, a module for reducing a step-up upper limit value of a converter from a predetermined normal upper limit value to a restricted upper limit value at a predetermined voltage reduction rate, and a module for determining an accelerator opening based on an accelerator operation performed by a user. When it is determined that the accelerator opening is equal to or greater than a predetermined threshold while the eco switch is ON, the step-up upper limit value of the converter is restored to the normal upper limit value from the restricted upper limit value at a predetermined voltage increase rate. | 12-02-2010 |
20110202222 | VEHICLE AND METHOD OF CONTROLLING THE SAME - A vehicle has a restriction storing device that stores a plurality of restrictions that are respectively created for a plurality of virtual gear ranges, such that, in each of the virtual gear ranges, required driving force as driving force to be applied to a drive shaft corresponding to the same accelerator operation amount tends to be increased as the vehicle speed is higher, and the required driving force corresponding to the same accelerator operation amount tends to be increased as the virtual gear range is shifted to a lower range when the vehicle speed is constant. | 08-18-2011 |
20130135742 | OPTICAL PRODUCT AND SPECTACLE PLASTIC LENS - An optical product includes an optical multilayer film on an optical product base. A color of reflected light of the optical multilayer film satisfies both of the following conditions in a chromaticity diagram (x,y,Y) of a CIE color system: [1] 0.27≦x≦0.30 and [2] 0.30≦y≦0.36. The optical product base is a spectacle plastic lens base. | 05-30-2013 |
20130175809 | VEHICLE - A hybrid vehicle includes a first motor-generator, which allows cranking an engine, and an inverter, which drives the first motor-generator. During running of the vehicle, when an operation to stop the hybrid system is performed, and then when an operation to start a hybrid system is performed before the vehicle stops, an HVECU operates the inverter. | 07-11-2013 |
20130179018 | CONTROL APPARATUS FOR VEHICLE - In a control apparatus for a vehicle, an ECU includes an operation reception unit that receives depression of a power switch (i.e., a vehicle system activation operation is performed) in a “ready-off state” as a non-drivable state, and a control execution unit that executes, when the vehicle system activation operation is received by the operation reception unit during running of a hybrid vehicle HV and an engine is started, a startability improvement control for improving startability of the engine as compared with the startability thereof when the vehicle system activation operation is received by the operation reception unit during stop of the hybrid vehicle HV and the engine is started. | 07-11-2013 |
20140365054 | CONTROL DEVICE FOR VEHICLE - If the accelerator is on upon restarting a driving force source in travel mode by the time when the vehicle comes to a standstill after the driving force source is manually operated to stop while the vehicle is traveling, a control device for the vehicle implements first control in which the driving force output to the drive wheels is gradually increased. If the accelerator is on upon switching to the travel mode following restarting of the driving force source in the neutral mode and by the time the vehicle comes to a standstill after the driving force source is manually operated to stop while the vehicle is traveling, the control device implements second control in which the driving force output to the drive wheels is increased. The first control increases the driving force not as much as the second control increases the driving force. | 12-11-2014 |
