Title: Controller for brushless motor and apparatus employing the same
Inventor: KAWABATA YUKIO
IPC: H02P6/06
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To detect rotor position immediately after commutation by comparing a first information signal pattern with a second information signal pattern and a third information signal pattern through an information signal pattern comparing means, and outputting a circulating current disappearance signal. SOLUTION: When a first information signal pattern is identical to a third information signal pattern and a second information signal pattern is different from other two information signal patterns, a circulation current is generated immediately after communication and disappears. Consequently, disappearance of the circulation current can be detected by comparing the first, second and third information signal pattern through an information signal pattern comparing means 6g and outputting a circulation current disappearance signal 14. Consequently, rotor position can be detected immediately after commutation based on an information signal pattern 13 generated from an information signal generating means 9 after detecting disappearance of the circulation current.

Title: Device for detecting steering angle
Inventor: SAWADA MAMORU
IPC: B62D111/00
Filed: 1988-08-10
Abstract: PURPOSE:To correctly identify a neutral position by a method wherein if change in a steering angle is lower than the specified value for a specified period or longer while a vehicle is identified to be traveling straight, the steering angle is identified to be at the neutral position. CONSTITUTION:On the basis of the results detected by a steering status detecting device M1, a steering angle calculating device M2 calculates a steering angle and inputs it to a steering neutral position identifying device M5. On the other hand, on the basis of the results detected by a travel status detecting device M3, a straight travel detecting device M4 identifies a status of straight travel and inputs to the steering neutral position identifying device M5. Said identifying device M5 identifies the vehicle to be at the steering angle neutral position if change in the steering angle is lower than the specified value for a specified period or longer within the time while the vehicle is traveling straight. Since the steering angle specified from the detected steering status is compensated according to the change in the steering angle while the vehicle is continuously traveling straight, identification that the steering angle is at the steering neutral position can be correctly attained.
