Abstract:
A method and apparatus of calculating a route involving a freeway junction determines an undesired freeway junction that can pose a driving difficulty, and performs route recalculation that avoids the undesired freeway junction. A distance from a freeway entry to a freeway junction, or a number of freeway entries up to the freeway junction are used to determine the undesired freeway junction. A distance from the freeway junction to a freeway exit is also used to determine the undesired freeway junction. An intermediate point is set to recalculate a route that does not involve the freeway junction to create an overall route.
Abstract:
A system of route scheduling for a vehicle presents fuel information for a vehicle. The system receives vehicle related drive information and fuel information from the vehicle via a vehicle interface, including fuel tank capacity, a current fuel level, and fuel economy, calculates routes to points from a current vehicle position based on the drive related information of sensors, estimates first fuel amounts for reaching the points based on the calculated routes and the fuel economy, selects fuel stations within a predetermined range of the calculated routes based on their locations, estimates second fuel amounts for reaching the fuel stations based on their locations, the fuel economy and the current vehicle position, obtains fuel prices of the fuel stations from a network, and instructs a screen to display the fuel prices, the point information, the locations of the fuel stations, the fuel tank capacity and the current fuel level along with a segment.
Abstract:
A clock information correction unit 15 is provided to correct the broadcast start/end times of an electronic program guide (EPG) generated in reference to the standard time. To perform this correction, the clock information correction unit 15 uses the standard time, which is the Greenwich Mean Time received by a standard time reception unit 11 of a broadcast reception device 100, and the clock time counted by an internal clock 21 of a head unit 200. The aforementioned correction is made based not on the time difference between time zones, but on the clock time of the internal clock 21. Thereby, without time zone setting based on GPS positional information or selection by a user operation, the broadcast start/end times of the EPG can be adjusted to correspond to the time of the internal clock.
Abstract:
On-board display control methods and systems are provided. In one implementation for displaying speedometer information and miscellaneous information on an instrument panel display, a nonuse region determination unit of an on-board display control device determines a nonuse speed region in a speedometer in accordance with a traveling status of a vehicle. A display control unit of the on-board display control device then exercises control such that an enlarged view of the miscellaneous information is displayed over the nonuse speed region when the nonuse region determination unit determines that there is the nonuse speech region.
Abstract:
A current location measured by a GPS receiver is defined as a base location. Individual points fairly near to the base location that are located on roads whose distances from the base location fall within a predetermined distance are set as candidate points. A distance between the base location and a candidate point to be evaluated is calculated. In a case where the distance is larger than a threshold value statistically estimated from a history of calculated distances between the base location and previously set candidate points that draw a trajectory on a road leading to the candidate point to be evaluated, the threshold value defining a rough upper limit of a distribution range of distances between the base location and the candidate points, it is judged that a true current location is not located on the road in which the candidate point is located.
Abstract:
A display device includes a liquid crystal display device that has a display area and a hidden area surrounding the display area; a liquid crystal shutter that is layered on the liquid crystal display device and has a first area corresponding to the display area and a second area corresponding to the hidden area; and a control unit that sets the first and second areas to a transparent state and an opaque state, respectively, when the display area is active, and sets the first and second areas to the opaque state when the display area is not active.
Abstract:
A method of pointing a first object on a screen of an infotainment system is provided. The first object on the screen is displayed on the screen and, a location of a second object related to a user and a first predetermined gesture executed by the second object by one or more sensors can be detected. Coordinates of a center of the first object on the screen can be calculated based on the detected location of the second object where the coordinates cause a distance between the center of the first object and the second object substantially minimum, and a size of the first object associated with a distance between the detected location of second object and the screen is calculated. The first object with the calculated size at the calculated coordinates is displayed on the screen.
Abstract:
An on-vehicle apparatus system and a terminal device protect personal information and location information readable from message information viewed by others. The on-vehicle apparatus, which is included in a vehicle and which is connected to the terminal device, includes an application for transmitting location information representing a position of the terminal device along with message information, to a message management system, and includes a first area determination unit which determines whether the position of the terminal device represented by the location information is included in a predetermined first area, and a posting controller, which bans assignment of the location information performed before the message information is transmitted to the message management system by the application, when the first area determination unit determines that the position of the terminal device is included in the first area.
Abstract:
A power supply device is mounted in a vehicle capable of starting an engine with power supplied from a battery, and includes a booster configured to boost voltage supplied from the battery, a detecting unit configured to detect an engine start, a counting unit configured to count an engine start count based on the detecting unit, and a control unit configured to control the booster. The control unit outputs a control signal to permit the booster to boost the voltage in response to the engine start when the engine start count counted by the counting unit within a timer period does not exceed an allowable number of times.
