Abstract: A microprocessor 214 obtains a vehicle travelled distance by multiplying the number of pulses by a distance factor R, the number of pulses having been outputted from a vehicle speed sensor 203 and having been counted by a counter 216. In addition, the microprocessor 214 estimates a current position on a road according to map data read out from a CD-ROM 205 via a driver 206, measured data from an angular velocity sensor 201 and a direction sensor 202 via A/D converters 209 and 210, and the obtained vehicle travelled distance. The road direction on the estimated current position and the vehicle direction obtained from the measured data of the angular velocity sensor 201 and the direction sensor 202, are compared, and in accordance with the angular difference therebetween and the information whether the driving road is a left turn or a right turn, it is determined whether the estimated current position is ahead or behind the actual position. With the result, the distance factor R can be dynamically modified. Therefore, it is possible to adequately correct the distance factor which is used for obtaining a travelled distance.

Abstract: A navigation system includes a driver presence sensor and engine running detection circuitry. When the detection circuitry determines that the engine of the vehicle is not running, the navigation system enters a low power mode. When the presence of the driver is detected, the navigation system begins power up, switching from a low power to a full power operational mode. If the detection circuitry does not determine that the engine is running within a predetermined time period, the navigation system reenters the low power mode. The detection circuitry monitors the vehicle's electrical system and determines that the engine is running when an AC content exceeds a predetermined threshold.

Abstract: The invention provides a vehicular navigation system which is capable of lowering the cost of detecting road data stored in order in the outgoing trip, using the road data as resources in the return trip, and determining a route meeting the requirements of the user. According to a vehicular navigation system of the invention, when a vehicle is traveling on a road having bidirectional data along an outgoing route from a starting point to a destination, a road on the opposite side of the road on which the vehicle is traveling is stored as return route data with a lowered cost of route determination. Such a storing operation is performed for each node passed by the vehicle. The return route data thus stored are used to determine a return route.

Abstract: In the disclosed navigation system, a distinctive object at an intersection or branch point already registered is recognized by image recognition in order that necessary action can be taken at the earliest opportunity by obtaining information as to the road on which the vehicle has advanced from the intersection or the branch point. The road on which the vehicle has advanced at the intersection or branch point is determined from the direction of relative movement of the distinctive object in the recognized image. Also, in order that easily understandable guidance can be provided even when intersections are in close proximity and even when a distinctive object is newly installed or removed at the intersection, assuming that the present position as detected is on the predetermined and guided route, a guidance message is composed by reading data relating to a point on the guided route, ahead of the present position, in the data stored in the information storage unit. The imaging is of the area of the road ahead using a video camera and the position of the distinctive object recognized in the image relative to the guidance point is determined and the preset guidance message is corrected based on that determination.

Abstract: A map of an entire region is divided into sections of a square of 900", each of which is further divided into blocks of a square of 30", each of which is further divided into units of a square of 1", so that a region on the map can be hierarchically designated. Each section is defined with section codes of three figures; each block is defined with block codes of three figures in accordance with its relative positional relation in the section; and each unit is defined with unit codes of three figures in accordance with its relative positional relation in the block, so that each unit can be completely differentiated with an intrinsic code of nine figures composed of those three kinds of codes. As to the section code composing the intrinsic code corresponding to the predetermined region, moreover, a number of significant digits is reduced by assigning a lower number in the code system, so that the manual operations of inputting the intrinsic code of the predetermined region can be lightened.

Abstract: To cancel an error in GPS wave propagation time and calculate a relative position of a car running nearby to the own car position with good accuracy, a relative car positioning system using car communication includes a car communication transceiver, a GPS receiving device, a GPS information transmission/reception device, and a relative positioning device. A relative position is determined by determining a GPS wave propagation time difference from a GPS satellite, a wave of which is received by the car running nearby and the own car in common. The difference between the data of GPS wave propagation time at the car running nearby and the data of GPS wave propagation time at the own car is calculated, and if the number of differences of the GPS wave propagation time is obtained by more than three pieces, a relative position of the car running nearby is calculated by solving simultaneous equations expression the relative position as an unknown quantity.

Abstract: A navigation system including a present-position sensing system for sensing a present position; information storage medium for storing map information; an input device for entering into the system the destination, a roundabout point, a bypass, and the location desired to be traversed for entry of input indicating the execution of a route search from the present position sensed by the present-position sensing system to the destination; an output device for outputting information route guidance; and a central processing unit including a route searching capability for searching for a route to the destination; a route storage capability for provisionally storing the identified route; and route guidance control for sending a signal for performing route guidance to the output device. When the roundabout point or bypass is entered in the system, a search cost for roads and intersections near to the roundabout point or bypass is raised so that route search processing can be performed. When the location desired to be traversed is set, roads near to the location desired to be traversed are retrieved for search purposes. In travel guidance, a present-position mark is displayed in either a continuous mode or a blinking mode depending on the state of travel.

Abstract: An integrated earth contouring system uses a postioning system such as a GPS system to track the location of an earthmover on a work site. A display device visible to a driver of the earthmover displays a difference between an existing surface contour and a desired surface contour of the work site. The display device may show a three-dimensional image which rotates or a two-dimensional image having a cursor which rotates to represent the earthmover. A blade sensor tracks the position of the earthmover blade, and the display is updated to show changes in the existing surface contour when the earthmover is moved on the site with the blade height between the height of the existing surface and the height of the desired surface. An orientation sensor on board the earthmover provides the microprocessor with the orientation of the earthmover, and a memory unit is provided to allow storage and retrieval of surface data by the microprocessor. The system can integrate the tracking of earthmover activity and surface development, as well as a utility line avoidance feature and a hydrology analysis function.
