CONTROL UNIT FOR ELECTRIC POWER STEERING DEVICE
PROBLEM TO BE SOLVED: To detect a bending load acting on a steering shaft only with a magnetostrictive torque sensor, without separately providing a sensor for detecting a bending moment.SOLUTION: The control unit stores, as an initial characteristic curve formed from initial detection values, a cha...

| description | PROBLEM TO BE SOLVED: To detect a bending load acting on a steering shaft only with a magnetostrictive torque sensor, without separately providing a sensor for detecting a bending moment.SOLUTION: The control unit stores, as an initial characteristic curve formed from initial detection values, a characteristic curve formed from detection values of each of a first detection coil and a second detection coil when only twisting torque is applied to a steering shaft 7 in a storage unit 31, and has a bending load detector 32 provided in an ECU 3 detects a bending load amount acting on the steering shaft 7 based on the difference between each detection value of the first and second detection coils and the initial detection value on the initial characteristic curve corresponding to the detection value. |
