Abstract: When a vehicle travels, due to an input from a road surface to the front wheels and rear wheels of the vehicle, unsprung vertical accelerations are generated in unsprung portions of the vehicle. An electronic control unit detects such unsprung vertical accelerations. The electronic control unit calculates a front-back force generated at each of the wheels by use of the detected unsprung vertical acceleration, and estimates a front-back vibration generated in each of the wheels. The electronic control unit calculates a front-back vibration suppressing force for absorbing the front-back vibration by use of the detected unsprung vertical acceleration. The electronic control unit subtracts the calculated front-back vibration suppressing force from the calculated front-back force, and operates the in-wheel motors via an inverter, while controlling the output torques of the in-wheel motors. Thus, the front-back vibrations of the unsprung portions of the vehicle can be suppressed.

Abstract: A tire state judging device (20) includes wheel speed sensors (22, 24, 26, and 28) configured to detect rotational speeds of tires, and a control unit 40 configured to perform frequency-analysis of detection results of the wheel speed sensors (22, 24, 26, and 28) to detect a frequency of a valley part of an output, and calculate an air pressure of the tire from the detected frequency of the valley part. According to this, the tire state judging device (20) has an effect that this can detect a state of the tire irrespective of a state of a road surface.

Abstract: A route searching apparatus includes a travel route accumulation unit, an algorithm selection unit to select route searching algorithms to meet the preference of a user based on the accumulated travel routes, and a route searching unit to perform a route search up to a destination by using the selected algorithms. Preferably, the algorithm searching unit searches for each of the travel routes accumulated in the accumulation unit by means of several algorithms, calculates, for each algorithm, a match rate between the searched route and the actual travel route, and selects an algorithm of the highest match rate. Also, it is preferable that a condition common to roads avoided by the user is extracted from the accumulated travel routes, and a route search is performed by adjusting search costs so as to make such roads less prone to be selected.

Abstract: The present invention relates to a mold device having a combination of molds for stretch blow molding, comprising a main blow mold 5, installed on a pair of platens 2 by being separated into split molds 5a, a pre-blow mold 10, attached to a lifting device 11 under the area between the split molds 5a, and movable in and out from the area between the split mold 5a, a neck mold 7, which is fitted into the pre-blow mold 10 and main blow mold 5 respectively, a blow core 20, which is fitted in to the neck mold 7, and a stretch rod. The pre-blow mold 10 comprises a cylindrical member having an open end on the upper portion, which is fitted into the neck mold 7. A bottom mold 8 of the main blow mold 5 is installed in the bottom portion of the split mold 5a by being separated into split bottom molds 8a. Lifting cylinders 9 are placed under the both of the split bottom molds 8a in order to make the bottom mold 8 movable in and out from the bottom portion of a cavity.
