When an ignition is turned off, an absolute steering angle detection value immediately before the ignition is turned off is stored as an absolute steering angle stored value in a memory and a CAN relative steering angle immediately before the ignition is turned off is stored as a relative steering angle stored value in the memory. When the ignition is turned on, a value obtained by correcting the absolute steering angle stored value with an angle value and the CAN relative steering angle) by which steering is performed during a period from the time when the ignition is turned off until the time when the ignition is turned on is set as an initial value of the absolute steering angle. A provisional absolute steering angle calculated value is calculated based on the relative steering angle, using the initial value of the absolute steering angle as a reference.
