摘要： PROBLEM TO BE SOLVED: To provide an electric power steering device which keeps an electric power motor under control by continuously running a predetermined electric current for return force generation thereto even when a steering angle sensor goes out of order, thereby performing the control of returning a steering angle by which the steering wheel is returned to a neutral position.
SOLUTION: The detected value of a steering angle output by the steering angle sensor 11 is input into a steering angles mixture calculation part 43 via a switch 51. Based on resolver information output by a resolver 14, a conversion steering angle is calculated at a conversion steering angle calculation part 42b, and the conversion steering angle thus calculated is input into the steering angles mixture calculation part 43 via a switch 52. The steering angles mixture calculation part 43 has a parallel redundant signal of the detected value of the steering angle and the conversion steering angle input thereinto, while weighting the detected value of the steering angle and conversion steering angle respectively for mixing them for generating a mixed steering angle. After that, a steering angle returning control is carried out by the mixed steering angle output from the steering angles mixture calculation part 43. Even if the resolver 14 becomes out of order, detected values of steering angles from the steering angle sensor 11 are continuously transmitted.

摘要： PROBLEM TO BE SOLVED: To make it possible to detect on-fault in the fail-safe relay of an H bridge circuit that drives the motor of an electric power steering device.
SOLUTION: If the fail-safe relay 47 is in on-fault when a first switching element 46a is turned on with a power relay 43 and the fail-safe relay 47 kept off, the voltage VMP of a second output terminal TM2, which should be otherwise held at pull-up voltage, is lowered to 0 V equal to the voltage of a first output terminal TM1 short-circuited to a low-voltage terminal TL. If the fail-safe relay 47 is in on-fault when a second switching element 46b is turned on with the power relay 43 and the fail-safe relay 47 kept off, the voltage VMN of the first output terminal TM1, which should be otherwise held at pull-up voltage, is lowered to 0 V equal to the voltage of a second output terminal TM2 short-circuited to the low-voltage terminal TL. Thus, any on-fault in the fail-safe relay 47 can be detected without fail.

摘要： PROBLEM TO BE SOLVED: To surely detect the ON fault of the switching circuit of the H bridge of an electric power steering device.
SOLUTION: If any of first to fourth switching elements 46a-46d of the H bridge circuit 41 has an ON fault, a high-voltage terminal TH and a low-voltage terminal TL short-circuit during a drive of a motor M, and a real current detected by a shunt resistor 42 is increased, and the real current hunts by the feedback control to bring this real current into conformity with a target current. So, this fault detector accumulates times, when the real current became larger than its upper limit value within a specified time and times when it became its lower limit value, and decides the occurrence of hunting, in short, the ON fault of the switching element, based on both accumulated times. Hereby, even in case the hunting real current within the ripple range of the real current at normal times, this discriminates between the ripple of the real current at normal times and the ripple of the real current at ON fault, whereby this can detect the ON fault of the switching element without fail.

摘要： PROBLEM TO BE SOLVED: To prevent improper neutral point renewing of a steering torque detecting means. SOLUTION: During a steering wheel is not operated, when a neutral point renewing work that stores an output signal ADVT3 of the steering torque detecting means read at each predetermined time as a neutral point signal is carried out, a past output signal TVLVT3(n) of the steering torque detecting means stored in advance and a present output signal TV3N0 of the steering torque detecting means are read. When a deviation between both output signals DVTCT is not less than a threshold value #RVTCT, renewing of the neutral point signal is prohibited. Therefore, in case that an operator touches the steering wheel during reading the output signal of the steering torque detecting means and the output signal of the steering torque detecting means indicates an abnormal value, the neutral point signal is prevented from being improperly renewed, and the detection accuracy of the steering torque detecting means can be ensured.
