PURPOSE:To make it possible to quantitatively detect the driving condition of a vehicle throughout its running by such an arrangement wherein an average value evaluated for every run of unit section when the detected value of the movement of the vehicle is larger than a specified value is calculated in sequence and a comprehensive evaluation of the vehicle is displayed. CONSTITUTION:An instantaneous driving condition judgement circuit 5 is provided an the circuit 5 compares a signal e6 of a reference value generating circuit 6 corresponding to a signal e3 of a running environment sensor 3 which detects the weather, etc. with a signal e2 of a vehicle movement sensor 2 detecting the lateral G. etc. of a vehicle, and generates a signal e5 for judging the driving condition of the vehicle. A unit section evaluation circuit 7 evaluates the signal e5 of the circuit 5 for every signal e4 of an oscillator 4 corresponding to a signal e1 of a running sensor 1, and a comprehensive evaluation circuit 8 calculates an average value for every unit section of the signal e7 of the circuit 7 and generates a signal e8 to cause a comprehensive evaluation display unit 11 to display value. By this arrangement, the driver of the vehicle is able to drive the vehicle safely and economically in accordance with the display of the unit 11. |
