| 20110221247 | OCCUPANT PROTECTION DEVICE AND CONTROL METHOD THEREOF - An occupant protection device includes a seat belt that restrains an occupant, an adjusting device that relatively adjusts a positional relationship between the seat belt and the occupant, a collision predicting portion that predicts a collision, and a control portion that controls the adjusting device when the collision is predicted by the collision predicting portion. The control portion first operates the adjusting device at a first speed to restrain the occupant by the seat belt, and then operates the adjusting device to increase the distance between the seat belt and the occupant at a second speed that is slower than the first speed. | 09-15-2011 |
| 20110291448 | OCCUPANT PROTECTION DEVICE - An occupant protection device includes: a seat cushion; a seat back; a base portion provided in a vehicle body; a support portion that is provided in the seat back and that overlaps a backrest of the seat back as viewed from front of a vehicle; a reclining angle adjustment portion that changes a reclining angle of the seat back by moving the support portion with respect to the base portion; and a contact portion that is provided in the vehicle body. If the support portion is displaced rearward in a longitudinal direction of the vehicle due to a rearward load that exceeds a prescribed magnitude being applied to the seat back, the contact portion comes into contact with the support portion on both the right and left sides of the seat back with respect to a center portion of the seat back. | 12-01-2011 |
| 20120032482 | VEHICLE SEAT CONTROL APPARATUS AND CONTROL METHOD THEREOF - A vehicle seat control apparatus includes an adjusting device that adjusts a reclining angle of a seat back of a vehicle seat, and a control portion that controls the adjusting device. When adjusting the reclining angle, the control portion controls the adjusting device to start adjusting the reclining angle at a first speed, and then after a predetermined period of time passes, the control portion controls the adjusting device to adjust the reclining angle at a second speed that is faster than the first speed. The invention also relates to a control method of this vehicle seat control apparatus. | 02-09-2012 |

| 20080228334 | Hybrid vehicle and control method thereof - During execution of an auto cruise function, in response to selection of a power mode, when an measured accelerator opening Acc is less than a preset opening Accref, a hybrid vehicle of the invention sets a power mode cancellation flag Fpmc to 1 and a power mode enabling flag Fpm to 0 (steps S540 and S550). This prohibits the use of an accelerator opening setting map in the power mode for execution of the auto cruise function. In the power mode, in response to an instruction for enabling the auto cruise function, the hybrid vehicle keeps the power mode enabling flag Fpm to the setting of 1 (step S560) as long as the measured accelerator opening Acc is not less than the preset opening Accref. This allows the use of the accelerator opening setting map in the power mode for execution of the auto cruise function. | 09-18-2008 |

| 20090211826 | HYBRID VEHICLE AND CONTROL METHOD OF HYBRID VEHICLE - On condition that a motor temperature is lower than a preset reference temperature and that a vehicle speed is lower than a preset reference speed, a booster circuit is controlled to adjust the voltage level of a high voltage system to be not higher than a certain low voltage. On condition that the motor temperature is lower than the preset reference temperature and that the vehicle speed is not lower than the preset reference speed, the booster circuit is controlled to adjust the voltage level of the high voltage system to be not higher than a maximum input voltage. On condition that the motor temperature is not lower than the preset reference temperature, the booster circuit is controlled to adjust the voltage level of the high voltage system to be not higher than the maximum input voltage, irrespective of the vehicle speed. This arrangement effectively improves the overall energy efficiency in a vehicle where the adjustment of the voltage level of the high voltage system to be not higher than the certain low voltage has the higher energy efficiency than the adjustment of the voltage level of the high voltage system to be not higher than the maximum input voltage. | 08-27-2009 |

| 20110006598 | CONTROL DEVICE AND CONTROL METHOD FOR VEHICLE - A vehicle includes a converter for stepping up power provided from a power storage device, and an inverter for converting the power output from converter and outputting it to an alternating-current motor for driving the vehicle. In the vehicle, a rectangular voltage control unit controls the inverter by means of rectangular wave voltage control that is based on a torque command value and the like, so as to control an output torque of the alternating-current motor. A system voltage control unit controls a system voltage, which is an output voltage of the converter. The system voltage control unit lifts a restriction on a system voltage command value based on an accelerator pedal position and the like, and then increases it. When increasing the system voltage command value during the rectangular wave voltage control for the inverter, a cooperative control unit increases the system voltage command value and the torque command value in a cooperative manner. | 01-13-2011 |
