摘要： A navigation system provides road guidance by displaying information relating to roads on a structure shape map, together with landmark information, in such a manner that only information around the present position is highlighted. The system retrieves road information in the direction of travel from the present position according to the vehicle speed, or road information within a predetermined angular or distance range in the direction of travel. Information relating to roads includes information indicating a one-way road, information indicating a road into which entry is prohibited, and information indicating a pedestrian crossing and a railroad crossing. These items of information are displayed by using marks, and the landmark information is displayed by using landmarks, thereby displaying information necessary for travel in a readily perceivable manner according to the travel conditions. When the vehicle enters a parking lot in the middle of the guidance for a route to a destination, the system searches for a route from the parking lot to the destination and outputs the found route by using a structure-shape map. The parking lot in this case is one within a predetermined walking distance from the destination. If the parking lot is in close proximity of the destination, further guidance is not necessary and the guidance is terminated.

摘要： In a navigation system, user preferred road data is determined and stored during travel to supplement fixed road data such as map data, intersection data, node data, and destination data stored in CD-ROM for subsequent use in providing route guidance in accordance with user road preferences. The user preferred road data is the data of actual trips, and the preference of the user is reflected in the user preferred road data. To determine user preferences, either the user preferred road data is compared to the fixed road data or a searched route calculated from the user preferred road data and CD-ROM data is compared with the searched route calculated from CD-ROM data. By using the determined user preferences in route searching, it is possible to provide more elaborate route searching and route guidance in accordance with the preference of the user.

摘要： A navigation system calculates a route from a present position of a vehicle to a destination and provides guidance based on the calculated route. When the vehicle is within a given distance from a next approaching branch point requiring guidance, branch points existing within a given distance from next approaching branch point are determined and direction information for the branch points is acquired. The acquired direction information is compared with direction information at the next approaching branch point, and a common direction information is displayed based on the result of the comparison. Also, the navigation system according to the present invention detects a name of an interchange where the vehicle is to exit from the course and a distance to said interchange based on the present position of the vehicle in case the road where the vehicle is currently driven along is an expressway or a toll road. The navigation system according to the present invention calculates a route from the present position to the destination and properly calculates and provides guidance for the expected time of arrival at the destination as the vehicle moves.

摘要： A solenoid driving circuit for an automatic transmission in which a potential difference compensating device, such as a Darlington-connected transistor circuit, switching transistor, and/or diode, is connected between a resistance element and a power ground, and a controlling device monitors voltage values at opposite sides of the resistor element so as to detect a current value flowing across a solenoid. The controlling device determines whether the detected value of the current flowing across the solenoid is abnormal, and the controlling device shuts off the current of a solenoid driving device when it is abnormal. The potential difference compensating device is provided with a switching device, and the controlling device turns off the switching device when the monitoring current value is abnormal. This circuit prevents an excessive current from flowing to the solenoid and an excessive discharge from the potential difference compensating device to the power ground owing to a short circuit with the supply line of a battery.

摘要： In a fail-safe control device for an electronically controlled automatic transmission to be mounted on a vehicle, a sensor for the number of revolution input to a T/M is newly provided for the electronically controlled automatic transmission, and an actual gear ratio of the T/M is calculated in accordance with the number of revolution input to the T/M and the number of revolution output from the T/M or the car speed. If the calculated actual gear ratio is coincided with the formal gear ratio, it is determined that the state is normal, while if they are not coincided with each other, it is determined that the T/M is in a failure state. As a result of this, failure detection of the T/M is performed. Therefore, in a case when the T/M is in a failure state, a driver can take a measure, for exmple, by performing an emergency control. Furthermore, the occurrence of the failure can be displayed by a detected failure displaying device so that the driver can take a measure such as a repair.
