摘要： PROBLEM TO BE SOLVED: To restrain the start and operation stop of an internal combustion engine from being operated frequently.
SOLUTION: The number of brief changes Nac indicating a frequency in which an accelerator opening degree Acc is less than a predetermined opening degree A2 of a predetermined opening degree A1 or below within predetermined time after exceeding the predetermined opening degree A1 is set (S410). The threshold for the start Astart is set to have a tendency to become larger as the set number of brief changes Nac is greater, and the threshold for the stop Astop is set to have a tendency to become smaller as the number of brief changes Nac is greater (S420 to S450). An engine and two motors are controlled so that a vehicle travels, by outputting the torque based on a requested torque to a drive shaft, accompanied by intermittent drive of the engine using a result obtained, by comparing a magnitude relation of the accelerator opening degree Acc and the threshold for the start Astart or the threshold for the stop Astop. Thus, the start and operation stop of the engine are restrained from being operated frequently, according to the number of brief changes Nac.

摘要： PROBLEM TO BE SOLVED: To provide a power detection device shortening a time required for power detection of three-phase power.
SOLUTION: This power detection device 1 adopts an addition circuit 301b constituted by having an operation amplifier 321 as a power operation part 301 for operating the three-phase power, based on the single phase power W1 detected by the single phase power detection part 101 and the two phase power W2 detected by the two phase power detection part 201. Hereby, since the single phase power W1 and the two phase power W2 are not converted from analog signals into digital signals, but operated in the state of the analog signals as they are, a time required for conversion from the analog signals into the digital signals is not required, to thereby shorten a time required for power detection of the three-phase power.
