Abstract
Abstract A sensor for detecting the degree of the operation of the accelerator in an automobile is provided and the display apparatus for expanding shrinking the display detection of the sensor is provided in the automobile so that the display apparatus can be observed from the outside. A apparatus for detecting the number of rotation of engine and the depressing degree of the brake pedal also provided. The number of the engine and the depressing degree of the brake pedal as well as operation degree of the accelerator pedal is displayed inside the car and outside the car by using the light emitting display apparatus. Apparatus for detecting the running speed of vehicle and the apparatus for detecting the acceleration and the deceleration of the vehicle are provided a plurality of different meaningful of character strings are displayed outside the vehicle in accordance with the detection status of the detecting apparatus to that the running status of the automobile is displayed. Based on the detecting apparatus for detecting the rotation direction of the clockwise direction or the anti-clockwise direction of the handle and the degree of the rotation is also detected by the detectors which can be observed from outside of the car and the moving running direction of the vehicle can be displayed.
