Method and apparatus for displaying brake stopping distance of a vehicle

Abstract

A method and apparatus for displaying the brake stopping distance of a running vehicle by computing and displaying in a very short period of time the brake stopping distance of the running vehicle in response to its running speed and the surface conditions of the road. The displayed brake stopping distance varies by quickly responding to changes in the running speed of the vehicle and the surface conditions of the road. The brake stopping distance displaying apparatus comprises a vehicle speed detecting circuit for generating a signal corresponding to the running speed of the vehicle, a setting circuit for generating a signal corresponding to the friction coefficient of the road on which the vehicle runs, a computing circuit responsive to the two signals to generate a signal proportional to the square of the running speed and inversely proportional to the friction coefficient, and a display circuit for displaying the result of the computation in the computing circuit.
