PURPOSE:To make the judgement of a driver direct and easy by displaying the ratio between the set value signal and the measured signal to a destination. CONSTITUTION:The electric signals according to the distance and required time to a destination, which is set a setting unit 3, are divided by the measured distance signal by a distance sensor 7 and a distance detecting unit 1 and by the measured detecting time signal by a time detecting unit 2 with the use of an arithmetic unit 4 so that the ratio between the set value and the measured value is displayed in a display unit 5. As a result, a driver can easily judge the running condition without any calculation using a map or mark. |
