摘要： A travel route indicating apparatus for use in an automotive vehicle, wherein a current travel route of the automotive vehicle in terms of two-dimensional coordinates may be obtained arithmetically by means of signal processing on the basis of the outputs from a travel distance detecting unit adapted to detect a current travel distance of the vehicle, and from a bearing detecting unit adapted to detect a resultant azimuth taken by the vehicle after travelling to a current point of travel, so that the thus obtained locational data on the location of the vehicle varying from time to time may be stored in sequence, and so that the travel path of the vehicle may be continuously visually indicated, as the vehicle travels, on the screen of a display from the thus-obtained travel data leading to the resulting current location of the vehicle.

摘要： A method of zero-level adjustment of a rate sensor wherein the zero-level adjustment in the detection of yawing rate is obtained by subtracting a quantity of drift of an output from the rate sensor during the period of time that the vehicle is stopped or standing still from a subsequent output therefrom in the normal travelling operation of the vehicle. The current state of the vehicle, i.e., whether it is travelling or standing still, is detected by a travel distance sensing device which generates electric pulse signals for a given unit distance travelled by the vehicle; and the sampled outputs from the rate sensor are averaged for the period from immediately after the detection of a standing still state of the vehicle to the moment just before a starting of travel thereof. The thus-obtained averaged value is determined as a current drifting value of the sensor and is subtracted from a current angle of deviation value obtained during normal travel of the vehicle. A substantial improvement in accuracy of zero-level adjustment is thereby attained.

摘要： A visual travel route indicating apparatus, for use in an automotive vehicle or the like, including a distance sensor for detecting a current distance of travel of the vehicle, a gas rate sensor for detecting a current azimuthal deviation generated by the vehicle during a turning motion, a thermostatic control chamber for enclosing the gas rate sensor hermetically from external temperature fluctuations, and a signal processing unit for arithmetically obtaining a current location plotted on two-dimensional coordinates per a given unit travel distance of the vehicle from the outputs of the two sensors and storing the thus-obtained location data in sequence so as to be read out subsequently for a continuous visual indication of a current locus of the vehicle on a display. The power supply to the thermostatic control chamber is optimally controlled in conjunction with the on/off state of the ignition switch of the vehicle. The visual indication of a current travel route of the vehicle is inhibited until the atmospheric temperature of the thermostatic chamber reaches a desired constant level, whereupon the offset adjustment of the gas rate sensor output is automatically normalized so as to present a precise visual indication of the vehicle's travel route on the display. Further, the occurrence of an abnormal temperature within the atmosphere of the thermostatic control chamber is detected so as to provide a warning to a driver of the vehicle.

摘要： An improved fixed range or distance indicating system for use in a visual travel route indicating apparatus of a vehicle. The fixed range indicating system minimizes memory capacity by discretely storing locational data obtained from discrete arithmetical calculation made at a suitable predetermined interval to present relatively short vector segments optimized in accordance with the given scale of indication on the display and at the same time provides a relatively high accuracy in approximating a current locational indication of the vehicle. A plurality of basic scales of indication varying with doubled denominators in accordance with a given variety of basic scales of indication are presented, the locational data are picked-up discretely at a rate corresponding to the plurality of basic scales of indication, and the thus picked-up locational data is stored into prescribed memory tables within a given limit of indication by way of an endless store mode. The current indicated path of travel on the display is erased at the interval of a fixed range travelled by the vehicle corresponding to the basic scales of indication, and refreshed points of indication are determined for a new location of the vehicle in accordance with a given scale of indication from the current points of indication for the current location at the time of erasing on the basis of the locational data read out from the memory table.
