To provide a system capable of issuing a warning with a margin for allowing a driver to drive a vehicle while suppressing generation of heat of a brake even temporarily so as to move the vehicle to a safe location when the brake of the vehicle at traveling undergoes abnormal heat generation.SOLUTION: An abnormal heat generation warning system for a vehicle brake includes: a sensor group including a brake temperature sensor, an outside air temperature sensor, and an acceleration sensor; a central controller which outputs an abnormal heat generation warning signal; and a warning device for issuing a warning to a driver when the signal is received from the central controller. The central controller defines, at a rise rate of a detected brake temperature higher than a set value, a temperature at which a brake may be ignited as a dangerous temperature, and a temperature lower than the dangerous temperature as a caution temperature. The warning device includes a caution temperature warning output unit for outputting a caution temperature warning, and a dangerous temperature warning output unit for outputting a dangerous temperature warning, and after the caution temperature warning is output, time until the temperature reaches the dangerous temperature is displayed from the warning device.SELECTED DRAWING: Figure 1
【課題】走行中の車両のブレーキが異常発熱したとき、一時的にでもブレーキの発熱を抑制しつつ車両の運転ができる余裕をもって警告を発出し、車両を安全な場所に移動させることができるシステムを提供する。【解決手段】車両ブレーキの異常発熱警報システムは、ブレーキ温度センサ、外気温度センサ、加速度センサを含むセンサ群と、異常発熱警報信号を出力するようにされた中央制御装置と、中央制御装置から信号を受取ったときに、ドライバーに警報を発出する警報装置と、を有し、中央制御装置は、検出されたブレーキ温度の上昇率が設定値より高くなり、ブレーキが発火する可能性のある温度を危険温度、危険温度よりも低い温度を注意温度とし、警報装置は、注意温度警報を出力する注意温度警報出力部と、危険温度警報を出力する危険温度警報出力部とを有し、注意温度警報の出力後は危険温度に到達するまでの時間を、警報装置から表示する。【選択図】図1
