20080262668 | Charge/discharge control apparatus for hybrid vehicle and control program device therefor - A navigation ECU records a charge-possible point through charging position record processing and records the history of traveling conditions near the charge-possible point through learning control processing. If a destination point on an optimum route is the charge-possible point, the navigation ECU determines a continuous section where the EV traveling is possible up to the charge-possible point based on the history through SOC management plan preparation processing, and changes over the HV traveling and the EV traveling according to the determination through in-travel processing. | 10-23-2008 |
20080269985 | Travel information collection apparatus - Travel information is categorized into plural time slot categories according to information characteristics of traffic flow information that represents a traffic flow of each of road sections in a database of an information center, and a learn database is built for each of the categories derived from above categorization. The travel information collected by a travel of a self vehicle along the road sections is learned according to the categories of the learn database for accurately managing the travel information according to the characteristics of the traffic flow. | 10-30-2008 |
20080270021 | Drive information collecting apparatus - A drive information collecting apparatus includes position specifying portion, storage control portion, and statistical confidence level storage portion. The position specifying portion specifies a present position of a vehicle and a road section. The storage control portion causes a storage medium to store a drive information item of each of the road section. The drive information item is collected while the vehicle travels. The statistical confidence level storage portion specifies a statistical confidence level based on a divergence between a predetermined reference value and the collected drive information item. The statistical confidence level indicates a degree of variation of the collected drive information item. The statistical confidence level storage portion associates the collected drive information item with the statistical confidence level and causes the storage medium to store the collected drive information item. | 10-30-2008 |
20080319596 | Charge-discharge management apparatus and computer readable medium comprising instructions for achieving the apparatus - After a final estimated route for a hybrid vehicle is specified, a navigation ECU determines a start point of a scheduled path, which a charging schedule is to be created for. The start point corresponds to a position at a travel distance, which is equivalent to a distance traveled from a present position of the hybrid vehicle along the estimated route for a time period required for creating a charging schedule. | 12-25-2008 |
20080319597 | Charge-discharge management apparatus and computer readable medium having instructions for achieving the apparatus - In charge-discharge control for a battery in a hybrid vehicle, when a difference between a target SOC (State Of Charge) and a present SOC becomes greater than or equal to a reference range in an estimated route to a destination, a charge schedule is drawn up again as a charge re-schedule. However, if the number of times of the re-schedule becomes greater than or equal to predetermined N times or if a remaining distance to the destination becomes less than a predetermined reference distance, a hybrid control based on the charge schedule is stopped without the charge re-schedule drawn up. | 12-25-2008 |
20100286896 | VEHICLE CONTROL SYSTEM AND METHOD USING NAVIGATION DATA - While a vehicle travels in a regular point, an absolute position of the vehicle is detected based on detection signals of a GPS sensor, a gyro sensor and a vehicle speed sensor. Then, a map matching process is performed such that the detected absolute position is corrected to be matched with a road map of map data. While the vehicle travels at a specific point, track position information of the vehicle based on the detected absolute position is stored independently of the map data. In particular, when the track position information regarding the specific point at which the vehicle is traveling at this point has been already stored, the information is sent to a light control unit, whereby the light control unit performs the optical axis control according to the traveling track indicated by the track position information. | 11-11-2010 |
