PURPOSE:To let a driver arrive at his destination easily regardless of whether the driver is aquainted with the way or not by obtaining a run command signal from previously inputted run information, and run distance and direction information, and giving the driver a guidance of run information on the basis of the obtained run command signal. CONSTITUTION:A car speed sensor 2 generates a pulse signal during a run and a run distance integrating circuit 1 integrates the pulse signal to calculate an actual run distance, threby sending the information to a controller 3 successively. The integral value is preferably reset automatically when a run mode starts to increase from zero, but a manual resetting circuit may be provided. The information on the actual run distance, etc., is displayed at the display part of a run information inputting circuit 6. The control circuit 3 compares the run distance information sent from the run distance integrating circuit 1, distance information sent from a direction sensor 9, and run information in a storage memory 7 to judge whether the car approaches a check point or not. When so, the control circuit 3 sends a command to a voice synthesizing and outputting circuit 4 before the check point to generate a voice output, thus guiding the driver through a speaker 5. |
