摘要： An automatic parking control is cancelled when a motor current has not yet reached a maximum current value Imax with a steering angle deviation exceeding a deviation threshold value. In addition, the automatic parking control is cancelled when a steering speed has not yet reached a maximum steering speed with a state where the motor current has reached and remains at the maximum steering speed continuing over a first time period. On the other hand, when a state where the steering speed has reached and remains at the maximum steering speed continues over a second time period, it is determined that there occurs an output shortage of a steering actuator, an automatic parking condition is recalculated, so as to allow the automatic parking continue to continue.

摘要翻译： 当电动机电流尚未达到超过偏差阈值的转向角偏差的最大电流值I MAX时，自动停车控制被取消。 此外，当电动机电流达到的状态下转向速度尚未达到最大转向速度并且保持在第一时间段内持续的最大转向速度时，自动停车控制被取消。 另一方面，当转向速度达到并保持在最大转向速度的状态在第二时间段内持续时，确定转向致动器的输出不足，重新计算自动停车条件等 以允许自动停车继续。

摘要： A ΣΔ analog-to-digital converter has a ΣΔ modulation section which executes ΣΔ modulation, and a digital filter which filters a digital signal output from the ΣΔ modulation section. The digital filter has gain properties that one of dips of a gain of the digital filter corresponds to a noise frequency which is, for example, the commercial frequency 60 Hz. Especially, the lowest frequency of the dips corresponds to the noise frequency.

摘要： A measuring apparatus includes a sensor unit, a processing unit, and a communication unit. The sensor unit may include at least one sensor that is configured to generate an output signal. The processing unit may be configured to be separate from the sensor unit. The processing unit may be configured to perform at least a first set of operations based on the output signal. The communication unit may couple the sensor unit and the processing unit. The communication unit may be configured to transmit the output signal as a digital signal from the sensor unit to the processing unit.

摘要： A control device able to find the intake air flow rate in an internal combustion engine having a plurality of intake passages upstream of a throttle valve is provided. The control device finds the intake air flow rate of the internal combustion engine by converting an output voltage of each of air flow sensors provided in the intake passages to a flow rate based on a relationship between an output voltage and flow rate found in advance for each air flow sensor, correcting the obtained flow rate in accordance with temperature characteristics of each the air flow sensor, and adding the corrected flow rates to calculate a total flow rate.
