A vehicle notification apparatus is provided and comprises: a brake device configured to press a frictional member against a rotating member integrated with a wheel when a brake request of the vehicle is generated so as to apply a frictional brake torque on the wheel; a wheel rotational speed sensor configured to generate a detection signal every time the wheel rotates by a predetermined angle; a notification execution device performing notification; and a control unit configured to obtain a wheel rotational speed based on the detection signal. The control unit is configured to: determine that a specific variation in the wheel rotational speed has occurred when the wheel rotational speed is determined to satisfy a predetermined specific variation occurrence condition; obtain, as a specific variation rotational angle position, a rotational position of when the specific variation has occurred based on the detection signal; specify a factor that has actually caused the specific variation based on the specific variation rotational angle position; and let the notification execution device provide information regarding the specified factor.

    本发明提供一种车辆报告装置,具备:制动装置,在产生了车辆的制动请求的情况下,使摩擦部件压接在与车轮一体旋转的旋转部件来使摩擦制动转矩作用于该车轮;车轮速传感器,每当车轮旋转规定角度,便产生规定的检测信号;报告执行装置,进行报告;以及控制单元,基于检测信号来取得车轮的旋转速度亦即车轮速。控制单元构成为:在车轮速满足预先决定的特异变动发生条件的情况下,判定为车轮速发生了与通常时不同的特异变动,基于检测信号来取得发生了特异变动时的车轮相对于规定的基准位置的旋转角位置作为特异变动旋转角位置,基于特异变动旋转角位置来确定使特异变动发生的因素,从报告执行装置报告与确定出的因素对应的信息。
