<p>PURPOSE: To prevent an accident such as collision from being generated by displaying deceleration like the deceleration by a foot brake even in the deceleration except by the operation of the foot brake, and also to accurately display the deceleration even if there is the slope on the road surface or the inclination of a vehicle, or even if vibration such as oscillation is generated on the vehicle. CONSTITUTION: The frequency-voltage conversion is performed by an f-v converting circuit 3 in relation to a pulse signal to be output from a wheel speed corresponding pulse output circuit 1, and having the cycle corresponding to the rotational speed of wheels, an acceleration or deceleration speed signal is obtained by differentiating the voltage signal by a calculating circuit 4, and it is compared with the set value of a display reference set circuit by a comparing circuit 6, and a display lamp 8 is turned on by a control circuit 7 according to the judged result for displaying the deceleration by the comparing circuit.</p> |
