A primary clutch of a continuously variable transmission with a launch mechanism is provided. The primary clutch includes a central post, a fixed sheave assembly, a movable sheave assembly and a locking mechanism. The central post is configured to receive rotational torque from a motor. The fixed sheave assembly is statically mounted on the central post. The movable sheave assembly is mounted on the central post. The movable sheave assembly includes a movable sheave system that is configured to move axially on the central post towards the fixed sheave assembly as RPM of the primary clutch increase. The locking mechanism is configured and arranged to selectively prevent movement of the movable sheave system independent of the RPM of the primary clutch.

A vehicle gear control method includes acquiring a driving scene image while a vehicle is driving, and performing image recognition on the acquired driving scene image to obtain a driving scene label including at least one of a road attribute label, a traffic attribute label, or an environment attribute label.

In a vehicle including an engine, drive wheels, a power transmission system, and an electronic control unit, during shifting of an automatic transmission, a hydraulic command value of a clutch is set to a higher value as an engine power command value is larger, so that a shift or change of the speed ratio proceeds in an electronic continuously variable transmission and the automatic transmission, in accordance with engine power as a product of the engine speed and engine torque, rather than torque of the engine, etc.

An automatic transmission controller is provided, which is capable of reducing occurrence of a shift shock while improving responsiveness of a driving force. An ECU is configured to calculate a target shift time based on an input torque that is input to the automatic transmission when a gear stage is shifted from a current gear stage to a target gear stage spaced two or more stages apart from the current gear stage. The ECU is also configured to: shift the gear stage to an intermediate gear stage between the current gear stage and the target gear stage when the target shift time is not less than a predetermined value; and to shift the gear stage directly to the target gear stage when the target shift time is less than the predetermined value.

A method for controlling a transmission provided in a vehicle may include providing a reference data for automatic shift of the transmission according to a speed reference of the vehicle, collecting a detected data delivered from at least one detector or operation state information related to an in-vehicle device, wherein the at least one detector and the in-vehicle device is attached or mounted on the vehicle configured for recognizing a driving condition, determining a mode for the automatic shift based at least on the detected data or the operating state information, and performing the automatic shift according to the mode.
