告装置。 A vehicle speed sensor that detects vehicle speed, a brake pressure sensor that detects brake pressure, a vehicle weight sensor that detects vehicle weight, deceleration determined from the vehicle speed signal from the vehicle speed sensor, and pressure signal from the brake pressure sensor. The above-mentioned detection device detects a fade phenomenon based on the obtained brake pressure and the degree of increase/decrease in vehicle weight from the basic vehicle weight obtained from the vehicle weight signal from the vehicle weight sensor and activates an alarm device. Inside the device,
A reference deceleration is set as a judgment criterion for each brake pressure, and a normal region and a fade region are established in which a deceleration at the time of deceleration of a vehicle is equal to or higher than the reference deceleration, and a fade is defined as below. A brake fade warning device characterized in that the brake fade warning device changes depending on the degree of increase/decrease in vehicle weight with respect to the basic vehicle weight.
