Abstract

PURPOSE: To prevent an unnecessary warning by determining whether or not the output of brake warning is generated on the basis of the output of a vehicle speed sensor in a brake warning device for warning when the vehicle travels with a side brake being not released.
CONSTITUTION: When a parking brake switch PBS is turned on, an ignition switch IGS is turned on. When an automobile starts and its speed exceeds 3km/h for example, the output of a vehicle speed sensor SPS is sent to a comparator CPM2 through a wave form shaping circuit WS and a frequency/voltage converting circuit FVC, and said comparator generates the output "1". Then, the pulse "1" is applied to the input of an NAND gate G1 by a differentiation circuit consisting of a capacitor C2 and resistance R2, and the outputs of G1, G2 become respectively "0", "1" and the output of G3 becomes "0". As a result, an alarm ALM makes a speaker SP produce a warning sound to warn an driver of a side brake being applied.
