Vehicle notification apparatus

A vehicle notification apparatus comprising:

• a brake device configured to press a frictional member against a rotating member rotating integrally with a wheel, when a brake requirement for a vehicle is generated so as to apply frictional brake torque to said wheel;
• a wheel rotational speed sensor configured to generate a detection signal every time said wheel rotates by a predetermined angle;
• a notification execution device configured to notify a passenger of said vehicle or a manager of said vehicle;
• and
• a control unit configured to obtain a wheel rotational speed that is a rotational speed of said wheel based on the detection signal,
• wherein,
• said control unit is configured to:
• determine whether or not said wheel rotational speed satisfies a predetermined specific variation occurrence condition;
• determine that a specific variation in said wheel rotational speed that does not occur in a normal driving state has occurred, when said wheel rotational speed is determined to satisfy said predetermined specific variation occurrence condition;
• obtain, as a specific variation rotational angle position, a rotational position of when said specific variation has occurred with reference to a predetermined reference position of said wheel, based on said detection signal;
• specify a factor that has caused said specific variation based on said specific variation rotational angle position;
• and
• let said notification execution device notify said passenger or said manager of information regarding said specified factor.
