To provide a vehicular brake alarm device capable of accurately issuing an alarm related to a vapor lock phenomenon occurring in a brake fluid in a vehicular brake device.SOLUTION: A vehicular brake alarm device includes temperature detecting means 35 for detecting a temperature of a brake fluid, water content detecting means 37 for detecting a water content of the brake fluid, a boiling point temperature map 39 in which relation between the water content contained in the brake fluid and the boiling point temperature is set for each type of the brake fluid, an alarm threshold temperature setting section 41 for determining a boiling point temperature in correspondence with the water content detected by the water content detecting means with the usage of the boiling point temperature map and setting an alarm threshold temperature based on the determined boiling point temperature, and a first alarm control section 43 for issuing a first alarm when the temperature detected by the temperature detecting means is equal to or higher than the alarm threshold temperature set by the alarm threshold temperature setting section.SELECTED DRAWING: Figure 1

    【課題】本発明の少なくとも一つの実施形態は、車両のブレーキ装置において、ブレーキフルードに生じるベーパーロック現象に関する警報を精度よく発することができる車両のブレーキ警報装置を提供することを目的とする。【解決手段】ブレーキフルードの温度を検出する温度検出手段35と、ブレーキフルードの水分含有量を検出する水分含有量検出手段37と、ブレーキフルードの種類毎にブレーキフルードに含まれる水分含有量と沸点温度との関係が設定された沸点温度マップ39と、沸点温度マップを用いて水分含有量検出手段によって検出された水分含有量に対応する沸点温度を決定し、該決定した沸点温度を基に警報閾値温度を設定する警報閾値温度設定部41と、温度検出手段によって検出された温度が、警報閾値温度設定部によって設定された警報閾値温度以上のとき第1警報を発する第1警報制御部43と、を備えることを特徴とする。【選択図】図1
