摘要： A hydraulic control apparatus of a vehicular automatic transmission has a plurality of hydraulic friction engagement devices that are selectively engaged and released to establish a plurality of forward speed change stages of different speed change ratios. The forward speed change stages are achieved through engagement of predetermined friction engagement devices, of the plurality of friction engagement devices. If it is determined that a predetermined speed change stage corresponding to a predetermined Shift output is not established, the hydraulic control apparatus identifies a hydraulic friction engagement device having a bad engagement that is a cause of the non-cstabJishment of the predetermined speed change stage, on the basis of the state of engagement oil pressure of the predetermined friction engagement device.

摘要： In a vehicle parking lock mechanism, a parking pawl (40) hinders rotation of a parking gear by engaging with the parking gear, and a lock member establishes a parking lock state by bringing the parking pawl (40) closer to the parking gear and moving to a lock position. The cam mechanism (96) includes a pair of a first roller (62) and a second roller (64) provided on the lock member. When the lock member is moved from an unlock position to the lock position, the first roller (62) brings the parking pawl (40) closer to the parking gear to be engaged with the parking gear and the second roller (64) restricts the lock member from displacing in a direction away from the parking pawl (40). An outer peripheral surface of at least one of the first roller (62) and the second roller (64) includes a fixing portion (110, 112) that protrudes toward the lock position.

摘要： In a vehicle parking lock mechanism (10), a parking pawl (40) mechanically hinders rotation of the parking gear (44) by being engaged with the parking gear (44). A lock member (42) is moved to the lock position to establish a parking lock state in which the parking pawl (40) hinders rotation of the parking gear (44). The support member (30) includes a guide portion configured to guide movement of the lock member (42) between the lock position and the unlock position while restricting the lock member (42) from displacing in a direction away from the parking pawl (40). The stopper (66) is rotatably mounted to either one member of the lock member (42) or the support member (30), changes a posture in accordance with relative movement between the lock member (42) and the support member (30), and protrudes toward the other member side of the lock member (42) such that the stopper (66) establishes a protruding posture in the parking lock state.

摘要： Provided is an automatic transmission for a vehicle having a compact device configuration.
At least one of a clutch (C) and a brake (B), which are a plurality of engaging elements, is a second clutch (C2) which is a meshing-type engaging element. As a result of at least a portion of the second clutch (C2) being provided on the inner peripheral side of a second one-way clutch (F2) and a third clutch (C3), which are other engaging elements, it is possible to minimize other configuration design changes when arranging the meshing-type engaging element, and to reduce the total length of the automatic transmission (10) as much as possible.
