Abstract
A vehicle brake warning device for use in a vehicle with a brake pedal includes a detector for producing different electrical signals in response to the magnitude of the inertia force experienced during braking, a control circuitry receiving signals from the detector and having a varying frequency output depending upon the received signal, and a warning device activated by the varying frequency output of the control circuitry. Whenever a pressing force is exerted on the brake pedal to reduce the speed of the vehicle, the detector experiences an inertia force whose magnitude depends upon the speed of the vehicle. The detector sends out an appropriate signal dependent upon the magnitude of the inertia force to the control circuitry. The control circuitry activates the warning device to send out a warning signal which varies depending upon the magnitude of the inertia force.
