摘要： In a navigation system arranged to display a road map in accordance with road map information from a cassette tape, and the present location of a motor vehicle equipped with the navigation system, a cassette tape distinguishing circuit is provided to a cassette tape player which picks up the road map information from a predetermined cassette having a window at given portion of the cassette housing. A switching circuit is responsive to the cassette tape distinguishing circuit so that the output data of the cassette tape is processed to display a given map only when a cassette carrying road map information is loaded in the cassette tape player. In the case a normal cassette carrying audio signals, such as music, is loaded the picked up audio signal is transmitted to an amplifier so that sound reproduction is effected. Thus, a single cassette player can be used in common as both a part of the navigation system and a part of a sound reproduction system.

摘要： In a vehicle-mounted navigator, a control unit reads map data from a memory unit and displays a corresponding road map on a CRT display unit. In response to signals from a distance sensor and a direction sensor, the present position in relation to the running of the automotive vehicle is computed to display by superimposition the present position on the road map display of the display unit. When the computed present position has reached to a predetermined portion of an adjacent area, the map data of the road map adjacent to the road map on display is read from the memory unit and a corresponding road map is displayed on the display unit manually or automatically. In accordance with this updated display, the present position display is moved to a corresponding position on the updated road map display.

摘要： An automotive navigator using a microcomputer displays a car position by a cursor on a road map displayed on a CRT screen. The navigator uses a cassette tape which stores a plurality of road map data and several kinds of reduced map data and expanded map data. It also uses a group of manual switches including a switch for changing the displayed area, a switch for selecting an expanded map or reduced map and a switch for moving the cursor position. Necessary data are displayed on the screen by the state of each switch. A region corresponding to the cursor position is displayed by the expanded map.

摘要： Disclosed is an azimuth determination apparatus attached to a motor vehicle for determinating the forward direction of the vehicle. The azimuth determination apparatus includes an azimuth sensor for generating orthogonal first and second signals indicative of the forward direction of the vehicle. Two azimuth vectors are obtained on the basis of the orthogonal first and second component signals, first components of the two azimuth vectors being maximum and minimum. The determination is made in terms of the fact that the difference between second components of the two azimuth vectors is below a predetermined value. In accordance with the determination, the orthogonal first and second component signals are corrected on the basis of said two azimuth vectors so that the accurate moving direction of the motor vehicle can be obtained irrespective of the remanence of the vehicle.
