摘要: Methods and systems for generating control instructions for a plurality of transmissions having dissimilar gear configurations via a common software framework are described. In one example, the common software framework provides a graphic interface whereby a user/implementer describes configurations of different transmissions. The software framework generates instructions for different transmission controllers that shift the transmissions.

摘要: A human-powered vehicle control device controls the transmission to initiate a shifting operation based on a set of prescribed conditions that changes the transmission ratio of a human-powered vehicle. The control device includes an electronic controller that switches between a first control state for controlling the transmission to change the transmission ratio in accordance with a first prescribed set of conditions, and a second control state for controlling the transmission to prevent the change of the transmission ratio as compared with if the electronic controller is in the first control state. The electronic controller switches between the first control state and the second control state in accordance with a detection of at least one of a steering state of the human-powered vehicle, a surface condition of a travel path on which the human-powered vehicle travels, and a pedaling preparation state related to the pedals of the human-powered vehicle.

摘要: A shift control method for a vehicle with a Dual Clutch Transmission (DCT) includes comparing, by a controller, a current clutch temperature with a first predetermined reference value and a second predetermined reference value, the second predetermined reference value being greater than the first reference value, preventing, by the controller, coaxial power-on downshifting when the clutch temperature is greater than the first reference value, and reducing, by the controller, a shift time by preventing coaxial power-on downshifting when the clutch temperature is greater than the second reference value and then increasing a shift speed when biaxial full skip shifting is required.

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: Vehicular drive system which is small-sized and/or improved in its fuel economy.A power distributing mechanism 16, which is provided with a differential-state switching device in the form of a switching clutch C0 and a switching brake B0, is switchable by the switching device between a differential state (continuously-variable shifting state) in which the mechanism is operable as an electrically controlled continuously variable transmission, and a fixed-speed-ratio shifting state in which the mechanism is operable as a transmission having a fixed speed ratio or ratios. The power distributing mechanism 16 is placed in the fixed-speed-ratio shifting state during a high-speed running of the vehicle or a high-speed operation of engine 8, so that the output of the engine 8 is transmitted to drive wheels 38 primarily through a mechanical power transmitting path, whereby fuel economy of the vehicle is improved owing to reduction of a loss of conversion of a mechanical energy into an electric energy. The mechanism 16 is also placed in the fixed-speed-ratio shifting state during a high-output operation of the engine 8, so that the required electric reaction of first electric motor M1 can be reduced, whereby the required size of the first electric motor M1, and the required size of the drive system 10 including the electric motor M1 can be reduced.

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.
