Disclosed is a gear shift indicator which can reduce bothersome feelings of the driver. The EFI-ECU acquires information about the travelling state of a vehicle, and calculates a target gear shift stage for improving fuel consumption. The EFI-ECU acquires information about a current gear shift stage. The EFI-ECU determines that a gear shift request is generated when the current gear shift stage is different from the target gear shift stage. When the EFI-ECU determines that an AI control is under execution and that the target gear shift stage calculated in the Step is a restricted gear shift stage prohibited in the AI control, the EFI-ECU does not present a gear shift indication.

An transmission servo assembly having a dual piston assembly for use in an automobile to transmission is described. The dual piston assembly includes a primary and a secondary piston that, when included within an assembly housing, provide surfaces that may be acted upon by a pressurized fluid so as to drive a servo pin into and away from a band within the transmission. The dual piston assembly allows for the application of a high apply force to servo pin while reducing the pressure of both an apply fluid and a release fluid, and therefore the amount of power used by a fluid pump external to the transmission servo assembly. The transmission servo assembly also substantially eliminates band drag by balancing the pressure applied to surfaces of dual piston system and by providing a biasing member designed and configured to provide suitable initial and ending forces to dual piston system.

System to control the torque of an internal combustion engine during a gear change

Номер: US20150120115A1
Автор: Masakazu Owatari, Masayasu Mizobuchi, Takaaki Tokura, Tomohiro Chinbe
Принадлежит: Toyota Motor Corp

An electronic control unit executes throttle torque reduction control for decreasing an engine torque by reducing a throttle opening degree during an upshift of an automatic transmission with respect to the throttle opening degree before a start of the upshift. During the upshift of the automatic transmission, the electronic control unit actuates a waste gate valve in a closing direction with respect to a position of the waste gate valve before the start of the upshift in parallel with execution of the throttle torque reduction control. Thus, a decrease in supercharging pressure due to execution of the throttle torque reduction control is suppressed during the upshift, and the engine torque that has been temporarily decreased in an inertia phase of the upshift recovers immediately after the upshift, so it is possible to suppress deterioration of drivability.
