| 20140159886 | DRIVING ASSIST DEVICE FOR VEHICLE - A vehicle operator assisting apparatus is configured to assist an operator of an own vehicle by displaying an image of a virtual preceding vehicle visually recognizable by the operator as if the virtual preceding vehicle was running in front of said own vehicle in a running state. The assisting apparatus comprises: a history data base storing a driving history of said operator; a virtual preceding vehicle control portion determining a running state of said virtual proceeding vehicle based on said driving history generating portion generating a relationship between a distance between said own vehicle and an actual preceding vehicle, and a running speed of said own vehicle, and storing the relationship in said history database. Said virtual preceding vehicle control portion includes a driving characteristics extracting portion determining a distance between said own vehicle and said virtual preceding vehicle based on said relationship. | 06-12-2014 |
| 20150180358 | POWER CONVERSION APPARATUS AND METHOD - A power conversion apparatus includes: a primary side full bridge circuit having a first arm circuit and a second arm circuit in parallel, a secondary side full bridge circuit having a third arm circuit and a fourth arm circuit in parallel, and a control unit configured to adjust a first phase difference between switching of the first arm circuit and switching of the third arm circuit and a second phase difference between switching of the second arm circuit and switching of the fourth arm circuit to control transmitted power that is transmitted between the primary side full bridge circuit and the secondary side full bridge circuit, wherein the control unit, among the first phase difference and the second phase difference, causes the phase difference between arm circuits having a higher efficiency to be larger than the phase difference between arm circuits having a lower efficiency. | 06-25-2015 |
| 20150263633 | POWER CONVERSION APPARATUS AND METHOD FOR STARTING UP THE SAME - A power conversion apparatus includes a transformer; a primary side full bridge circuit provided on a primary side of the transformer; a first port connected to the primary side full bridge circuit; a second port connected to a center tap of the primary side of the transformer; a secondary side full bridge circuit provided on a secondary side of the transformer; a third port connected to the secondary side full bridge circuit; and a control unit configured to cause an upper arm of the secondary side full bridge circuit to operate in an active region in a case where a capacitor connected to the third port is charged with a transmitted power transmitted to the secondary side full bridge circuit via the transformer from the primary side full bridge circuit when power of the second port is stepped up and the stepped up power is output to the first port. | 09-17-2015 |
| 20150295445 | ELECTRIC POWER CONVERSION APPARATUS AND METHOD OF CONTROLLING THE SAME - Assuming that a transformer has a primary to secondary winding turn ratio 1:N, VR denotes a voltage of regenerated power, VCd denotes a discharge final voltage of a first battery connected with a transformer-primary-side center tap, VCc denotes a charge final voltage of the first battery, VBd denotes a discharge final voltage of a second battery connected with a transformer-secondary-side full bridge circuit, VBc denotes a charge final voltage of the second battery and Drain denotes a lower limit of a duty ratio D of a transformer-primary-side full bridge circuit, an apparatus determines upon (VBd/N)≦VR≦(VBc/N) that the first and second batteries may be able to be charged with regenerated power and determines upon VCd≦VR≦(VCc/Dmin) that the first battery may be able to be charged with the regenerated power. | 10-15-2015 |
| 20150295504 | ELECTRIC POWER CONVERSION APPARATUS AND METHOD OF CONTROLLING THE SAME - An electric power conversion apparatus includes a transformer having a primary coil and a secondary coil; a primary-side full bridge circuit having first and second arm circuits in parallel, respective midpoints of the first and second arm circuits being connected via the primary coil; a secondary-side full bridge circuit having third and fourth arm circuits in parallel, respective midpoints of the third and fourth arm circuits being connected via the secondary coil. The number of turns of the secondary coil between the latter respective midpoints is switched and transmission power transmitted between the primary-side and the secondary-side full bridge circuits is controlled through adjustment of a phase difference in switching between the first arm circuit and the third arm circuit and a phase difference in switching between the second arm circuit and the fourth arm circuit. | 10-15-2015 |
| 20150315991 | VEHICLE CONTROL SYSTEM - The present invention relates to a vehicle control system for executing a fuel saving control effectively by making an assessment of effectiveness of the control based on a learned value obtained from an actual running. The vehicle control system is configured to execute the fuel saving control by stopping fuel supply to an engine upon satisfaction of a predetermined condition. The control system makes an assessment of the fuel saving control by learning fuel consumption within a predetermined learning zone, and inhibits the fuel saving control or executes another control in the learning zone next time the vehicle travels through the learning zone, if the assessment shows a fact that the fuel saving control executed in the learning zone did not effective to save fuel. | 11-05-2015 |
