Abstract: A transmission ratio controller includes circuitry. The circuitry includes a transmission ratio calculator configured to calculate a request transmission ratio to a transmission mechanism, a transmission ratio instructor configured to output a control signal based on the request transmission ratio, and an abnormality determiner configured to determine whether a transmission ratio of the transmission mechanism is abnormal. At least two of the request transmission ratio, an instruction transmission ratio corresponding to the control signal, or an actual transmission ratio achieved by the transmission mechanism are transmission ratios subject to comparison. The abnormality determiner is configured to determine that when a difference obtained by comparing the transmission ratios subject to comparison is greater than or equal to a predetermined specified value, the transmission ratio of the transmission mechanism is abnormal.

Abstract: A transmission ratio controller includes circuitry that includes a transmission ratio calculator calculating a request transmission ratio, a transmission ratio instructor transmitting a control signal, and an abnormality determiner. The request transmission ratio is calculated using a first transmission ratio map when a specified parameter satisfies a first condition, and a second transmission ratio map when the specified parameter satisfies a second condition. The internal combustion engine is in a first state when the specified parameter satisfies the first condition, and in a second state when the specified parameter satisfies the second condition. In the first state, the abnormality determiner calculates a hypothetical transmission ratio using the second transmission ratio map based on the second state. The abnormality determiner determines an abnormality based on a comparison of the hypothetical transmission ratio with at least one of the request transmission ratio, an instruction transmission ratio, or an actual transmission ratio.

Abstract: A transmission ratio controller includes circuitry including a transmission ratio calculator and a monitor. The transmission ratio calculator calculates a transmission ratio using a first transmission ratio map when a specified parameter satisfies a first condition, and using a second transmission ratio map when the specified parameter satisfies a second condition. When the specified parameter satisfies the first condition, the internal combustion engine is in a first state. When the specified parameter satisfies the second condition, the internal combustion engine is in a second state. In the first state, the monitor calculates a hypothetical transmission ratio using the second transmission ratio map based on the second state. On a condition that the transmission ratio calculated in the first state differs from the hypothetical transmission ratio by a predetermined reference value or greater, the monitor determines that the transmission ratio has a possibility of differing in accordance with the specified parameter.

Abstract: The electric power generating device includes a first generator, a differential gear mechanism provided between a blade and the first generator, a first ring gear connected to the first generator, and a case that rotates integrally with the first ring gear about a first axis. The differential gear mechanism includes a pinion shaft that rotatably supports a pair of pinion gears about a second axis perpendicular to the first axis. The differential gear mechanism includes a first drive shaft having a first side gear at one end and a blade connected to the other end. The differential gear mechanism comprises a second drive shaft having a second side gear at one end and having an interference portion at one end extending toward the pinion shaft. The interference portion faces the pinion shaft in a direction of a third axis that is orthogonal to the first axis and the second axis.

Abstract: A plug for a vehicle includes: a body portion; a plurality of insertion portions configured to be inserted into a through-hole provided in a housing; and a flange portion having a notch formed on an outer periphery so as to restrict a rotation of the body portion around an axial center. The insertion portions are formed at two positions opposed to each other across a straight line passing through the notch and the axial center and are provided with retaining lugs engageable with the through-hole.

Abstract: A supercharging system includes a waste gate valve and an ECU. The ECU is configured to: calculate a first parameter and a second parameter, each of which has a positive correlation with an intake air amount; obtain a first difference by subtracting a first boost pressure from a second boost pressure; obtain a second difference by subtracting the first parameter from the second parameter; obtain a quotient by dividing the first difference by the second difference; and determine that a malfunction occurs in the waste gate valve when the quotient is larger than a threshold value.
