Abstract: An ADC has ADC channels converting an analog input signal into an digital output signal in a time interleave manner; a channel combiner combining channel digital signals respectively output by the ADC channels and generate the digital output signal; an adaptive filter provided at one of the plurality of ADC channels; and a correction circuit detecting a skew error in the digital output signal, generating a coefficient of the adaptive filter according to the skew error for setting it in the filter. According to the skew error, in a first setting, the correction circuit sets the coefficient such that the adaptive filter phase-shifts to one direction a phase of the channel digital signal and, in a second setting, the correction circuit sets the coefficient such that the adaptive filter phase-shifts to an opposite direction and sets a coefficient with which the skew error is suppressed to a desired level.

Abstract: Provided is a motor control apparatus that can easily distinguish between a current sensor abnormality and a rotation-angle sensor abnormality, without making a current sensor a duplex system. An MGECU (140) estimates a W-phase current on the basis of a V-phase current detected by a current sensor (125), and estimates the V-phase current on the basis of a detected W-phase current. An actual torque of a motor generator MG2 is estimated on the basis of the detected V-phase current and the estimated W-phase current, and the actual torque of the motor generator MG2 is also estimated on the basis of the detected W-phase current and the estimated V-phase current. Then, an evaluation is made whether an abnormality is an abnormality of the current sensor (125) or an abnormality of a resolver (124), on the basis of the differences between the torque command value for the motor generator MG2 and both the estimated actual torques.

Abstract: An ADC which samples an analog input signal at a sampling frequency and converts the analog input signal to a digital output signal, has N analog digital converter (ADC) channels which convert the analog input signal into the digital output signal by time interleaving, a channel synthesizer which synthesizes channel digital signals output respectively by the ADC channels to generate the digital output signal, an adaptive filter provided at at least one output of the ADC channels, and a correction circuit which generates a coefficient of the adaptive filter in accordance with the digital output signal. The correction circuit calculates a DC component of an image signal component, from among an analog input signal component and the image signal component corresponding to error, both being included in the digital output signal, and calculates the coefficient such that the DC component is suppressed on the basis of the DC component.

Abstract: When the detected value of a rotation speed sensor is normal, it is determined whether or not a vehicle is stopping by using a predetermined rotation speed N1 as a stop determination upper limit rotation speed Nojmax, and when the detected value of the rotation speed sensor is not a normal value due to a magnetic field or the like from a road heater, it is determined whether or not the vehicle is stopping by using a predetermined rotation speed N2 which is larger than the predetermined rotation speed N1as the stop determination upper limit rotation speed Nojmax. Thereby, it can be more properly determined whether or not the vehicle is stopping in accordance with whether or not the detected value of the rotation speed sensor is normal.

Abstract: When the detected value of a rotation speed sensor is normal, it is determined whether or not a vehicle is stopping by using a predetermined rotation speed N1 as a stop determination upper limit rotation speed Nojmax (S130, S160, S180 to S200), and when the detected value of the rotation speed sensor is not a normal value due to a magnetic field or the like from a road heater, it is determined whether or not the vehicle is stopping by using a predetermined rotation speed N2 which is larger than the predetermined rotation speed N1 as the stop determination upper limit rotation speed Nojmax (S130, S170, S180 to S200). Thereby, it can be more properly determined whether or not the vehicle is stopping in accordance with whether or not the detected value of the rotation speed sensor is normal.

Abstract: An ECU executes a program including the steps of: when a DC/DC converter is boosting the voltage, calculating a VB estimate value, and if a state, where an absolute value of a difference between the VB estimate value and a VB value sensed by a VB sensor is at least a voltage threshold value X, has been continuing for a predetermined time, determining that the VB sensor is tentatively abnormal; if a state, where an absolute value of a difference between a VH voltage instruct value and a VH value sensed by a VH sensor is at least a voltage threshold value Z, has been continuing for a predetermined time, determining that the VH sensor is tentatively abnormal; and if the sensor is tentatively abnormal, stopping boosting, and specifying the abnormal sensor based on the deviation of the VB value and the VH value.

Abstract: An ECU performs a program. In the program, in the case where a converter is performing an operation for increasing a voltage (i.e., YES in step S 102), when a difference between an estimated battery voltage VBE and a battery voltage VB has continued to be large (i.e., YES in step S 104), the ECU tentatively determines that a battery voltage sensor is abnormal (S 106), and stops voltage increasing control for the converter (S 108). If an absolute value of a difference between a battery voltage and an output side voltage is large (i.e., YES in step S 110), a difference A which is an absolute value between an estimated battery voltage and a battery voltage, and a difference B which is an absolute value between the estimated battery voltage and an output side voltage are calculated (S 112). If a value obtained by subtracting the difference B from the difference A has continued to be large (i.e., YES in step S 114), it is determined that the battery voltage sensor is abnormal (S 116).
