Abstract
Steering angle detecting apparatus of a steering is constituted to dispense with reexecution of initial setting by a simple angle sensor. CPU is connected with an MR sensor attached to a rotating member rotated in cooperation with a steering shaft for detecting a periodic angular position and CPU subjects data from the MR sensor to an operation processing by using a reference position stored to an involatile data storing portion to thereby calculate an absolute steering angle including a number of an order of turns. When an ignition is made OFF, there is constituted a low current consumption mode for carrying out calculation by intermittent operation and power source to the MR sensor is made OFF by a sensor switch. The reference position is stored to the involatile data storing portion and therefore, even after detaching and attaching a battery, initial setting is dispensed with.
