Abstract
When a car is traveling ahead of the car on which a route guidance device of this invention is carried, the route guidance device determines the distance D to the preceding vehicle and judges whether or not an intersection where the driver is to be guided is within the distance D from the preset location of the device-loaded vehicle. Namely, the device finds the timing at which the preceding vehicle enters the intersection. At that timing, the device gives a guidance based on the behavior of the preceding vehicle by announcing such a message that 'Turn left at the intersection the preceding vehicle is now at', 'Turn left at the intersection where the preceding vehicle is turning', 'Turn left at the intersection the preceding vehicle is now passing straight through.', etc. Therefore, easily understandable guidance can be given at an intersection where the driver is to be guided.
