Patent number: 11801895Abstract: A control device includes a processor and a storage device storing a program for controlling an operation of the processor. The processor determines whether a vehicle is in a straight-ahead traveling state, based on a vehicle speed detected by a vehicle speed sensor, a steering wheel torque applied to a steering wheel, and a steering wheel angle as a rotation angle of an input shaft. The processor stores the steering wheel angle in the memory when determining that the vehicle is in the straight-ahead traveling state. The processor stores the steering wheel angle in the memory multiple times when determining that the vehicle is in the straight-ahead traveling state. The processor calculates a corrected steering angle amount from a weighted average of the steering wheel angles stored in the memory.Type: GrantFiled: July 6, 2021Date of Patent: October 31, 2023Assignee: NIDEC CORPORATIONInventors: Sohei Miyake, Jun Ogawa, Satoru Onishi, Masaya Ishikawa
