The vehicle notification apparatus comprises: a brake device configured to press a frictional member against a rotating member; a wheel rotational speed sensor configured to generate a detection signal every time the wheel rotates by a predetermined angle; a notification execution device; 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.
