    Abstract: A hybrid vehicle driving apparatus includes a clutch control device and an automatic transmission control device that are connected to mutually communicate. The clutch control device sends a request to wait gear shift to the automatic transmission control device while front clutch operation is in preparation. The automatic transmission control device that receives the request to wait gear shift determines whether priority is given to engaging or disengaging the front clutch or to shifting gears of the automatic transmission. The automatic transmission control device that is determined to give priority to the front clutch operation sends out a gear shift in stand-by state signal to the clutch control device while maintaining the automatic transmission in a gear shift prepared state. The clutch control device that receives the gear shift in progress signal restrains the front clutch from engaging or disengaging while maintaining the front clutch in an operation prepared state.

  • Patent number: 8442731
    Abstract: A control system for an electronically controlled continuously variable transmission of a straddle type vehicle in which an intentional shift down operation is easily made in an AT mode. An MT mode temporarily selecting section makes the gear change mode selecting section select the MT mode temporarily and makes the gear ratio control section change the gear ratio of the transmission to a gear ratio from among a plurality of predetermined gear ratios that is positioned lower than a current gear ratio when a mode change signal is inputted in AT mode. An AT mode returning section returns the gear change mode selected by the gear change mode selecting section to AT mode when a release signal is outputted after MT mode is temporarily selected by the MT mode temporarily selecting section.

    Abstract: A linear solenoid is configured with an electromagnetic coil and a label resistor that are integrated with each other; the label resistor has a resistance value corresponding to a correction coefficient based on the difference between the actual characteristic of the supply current vs. adjusted hydraulic pressure output of the electromagnetic coil and a standard characteristic; and data for correcting a characteristic variation in the command current vs. output current characteristic of an electromagnetic coil is preliminarily stored in a control module by use of an adjustment tool. When the operation is started, the resistance value of the label resistor is read and an output current corresponding to a utilized linear solenoid is supplied, so that a target adjusted hydraulic pressure is obtained.
