    摘要: A vehicle includes a motor, a resolver which detects a rotation angle of the motor, an automatic transmission which shifts rotation of the motor and transmits the shifted rotation to a drive shaft, and an ECU which performs learning control for correcting an error of the resolver and shift control of the automatic transmission. The ECU controls the automatic transmission such that, when the learning control is performed, a gear ratio becomes higher at a prescribed vehicle speed, than that when the learning control is not performed. By controlling the automatic transmission as described above, even when the vehicle is traveling at a low speed, a rotation speed of the motor easily reaches a rotation speed at and above which the learning control of the resolver can be performed. Accordingly, an opportunity to perform the learning control of the resolver can be obtained early.

    摘要: In a gear shift control device for a vehicle that shifts a transmission having a plurality of gears based on a shift line set in a shift map, an upshift line for shifting to the highest gear, and a downshift line that is located in a high vehicle speed region on the side of a higher vehicle speed than the upshift line are set in the shift map. The downshift line is used when shifting from the highest gear to a prescribed gear that has a larger gear ratio than the highest gear.

    摘要: The shift control method of an automatic transmission calculates a shift-pattern-adjusting coefficient using a modular neural network. The shift-pattern adjusting coefficient is based on a plurality of input signals input from a plurality of detectors. It is then determined if shifting is required based on an adjusted shift-pattern. The adjusted shift-pattern being adjusted based on the shift-pattern adjusting coefficient. A target shift-speed when shifting is required is calculated based on the adjusted shift-pattern. Finally, a shifting signal for shifting to the target shift-speed is generated.
