A shift range control device switches a shift range by controlling driving of a motor. A learning unit learns, as a position correction value, a normal state time correction value calculated based on first and/or second reference angles when an output shaft signal is available when turning on of a start switch. The first reference angle is a motor angle when the output shaft signal changes in response to the rotation of the motor in a first direction. The second reference angle is the motor angle when the output shaft signal changes in response to the motor rotation in a second direction opposite to the first direction. A motor angle target value is set by using the normal state time correction value stored during a period from when all the output shaft signals are determined to be unavailable to when the start switch is turned off.

A bicycle controller is configured to communicate with a first bicycle component that transmits a first wireless signal and a second bicycle component that transmits a second wireless signal. The bicycle controller includes an interface configured to receive the first wireless signal and the second wireless signal. The first wireless signal has a center frequency that is a first frequency. The second wireless signal has a center frequency that is a second frequency. The second frequency differs from the first frequency.

A mechanical creeper mode selection system for a transmission of a work vehicle is provided, in which the transmission includes one or more range modes having one or more range mode shift mechanisms each driven by an electrohydraulic circuit. The system includes a creeper mode selection lever movable by an operator to select a creeper gear range. The system also includes a sensor that observes a position of the creeper mode selection lever and generates sensor signals based thereon. The system includes a controller that processes the sensor data to determine a movement of the creeper mode selection lever and outputs one or more control signals to the electrohydraulic circuit to position the one or more range mode shift mechanisms in a range neutral mode based on the movement of the creeper mode selection lever.

A shift selector device includes an input member, a position setting mechanism and an activation controller. A selection operation of selecting a shift position is input to the input member. The position setting mechanism defines a movable range of the input member while supporting the input member in a displaceable manner. A plurality of the shift positions and at least one activation position linked to an automated travel system are disposed in the movable range. When the activation position is selected by displacement of the input member, the activation controller outputs an activation instruction for instructing a control function of the automated travel system linked to the activation position to be activated.

A method of controlling gear selection in a vehicle transmission comprises detecting a change in a direction control signal (DCS) from a neutral signal state. If the current TOS is less than or equal to a predetermined neutral shift threshold TOS, the transmission selects one of a plurality of first direction gears if the DCS was changed to a first direction signal state or one of a plurality of second direction gears if the DCS was changed to a second direction signal state. If the current TOS is greater than the predetermined neutral shift threshold TOS, the transmission selects one of the plurality of first direction gears if a machine motion direction parameter indicates that the vehicle is moving in the first direction or one of the plurality of second direction gears if the machine motion direction parameter indicates that the vehicle is moving in the second direction.

A derailleur shifting system comprise a front derailleur, a rear derailleur, an operating device and a controller. The front derailleur is configured to be controlled to shift among front gear positions. The rear derailleur is configured to be controlled to shift among rear gear positions. The operating device is configured to generate an operational instruction associated with one or both of the front derailleur and the rear derailleur. The controller is configured to control one or both of the front derailleur and the rear derailleur to shift according to the operational instruction, an estimated gear position table and a gear position control table. The estimated gear position table comprises an estimated front gear position of the front derailleur and an estimated rear gear position of the rear derailleur, and the gear position control table comprises matching relationships between the front gear positions and the rear gear positions.

A hydraulic control system for a transmission is provided with a power source, two drive wheels, a power transmission device, a hydraulic pump, a main valve, and a controller. The power transmission device is configured to be set to a plurality of speed stages. The main valve is disposed between the hydraulic pump and the power transmission device and adjusts the main pressure of hydraulic fluid supplied from the hydraulic pump to the power transmission device. The controller controls the main valve. The controller sets the main pressure to a pressure value derived by correcting a clutch holding pressure of the set speed stage based on a load applied to each of the drive wheels.

Among other things, this document describes systems, devices, and methods for improving the delivery and performance of web pages authored to produce virtual reality (VR) or augmented reality (AR) experiences. In some embodiments, such web pages are analyzed. This analysis may be initiated at the request of a content server that receives a client request for the HTML. The analysis may involve, asynchronous to the client request, loading the page into a non-user-facing browser environment and allowing the VR or AR scene to execute, even including executing animation routines for a predetermined period of time. Certain characteristics of the scene and of objects are thereby captured. Based on this information, an object list ordered by loading priority is prepared. Consulting this information in response to subsequent requests for the page, a content server can implement server push, early hints and/or other delivery enhancements.

An actuator diagnostic apparatus is provided for an electronic control unit of a vehicle.
