<P>PROBLEM TO BE SOLVED: To provide a tilt angle sensor middle point correction method capable of performing middle point correction by a simple structure, and to provide a vehicle tilt angle display apparatus. Ž<P>SOLUTION: When a stopping condition acquisition means 4 detects the stopping of a vehicle, a middle point correction control unit 17 detects that an oil filler port lid has been opened and that an oil filler port SW 9 has been turned ON, determines that the vehicle has stopped at a gas station for refueling, performs middle point correction control, acquires a new longitudinal tilt angle reference value and lateral tilt angle reference value, stores them in a longitudinal tilt angle reference value storage unit 15a and a lateral tilt angle reference value storage unit 16a, respectively, and updates them with the new longitudinal tilt angle reference value and lateral tilt angle reference value. Thereafter, correction calculation units 15, 16 can thereby perform correction calculations using the newly updated longitudinal tilt angle reference value and lateral tilt angle reference value.
