Abstract: Methods and systems for a hydromechanical transmission. In one example, a vehicle system includes a hydromechanical transmission with a power-take off (PTO) that is designed to rotationally couple to an implement. The vehicle system further includes an engine coupled to the hydromechanical transmission and a power-management control unit configured to, during a drive or coast condition, cause the power-management control unit to: determine a net available power for the hydromechanical transmission and manage a power flow between the hydromechanical transmission, a drive axle, and the implement based on the net available power.

Abstract: A shifting system for a human-powered vehicle comprises a controller. The controller is configured to receive a driving torque and a cadence of the human-powered vehicle from at least one sensor. The controller is configured to determine a permitted shift timing based on the driving torque and the cadence. The controller is further configured to control a shift mechanism to perform a gear shift during the permitted shift timing in accordance with a permitted cadence range and a first threshold of the driving torque.

Abstract: A valve arrangement structure of a control valve unit includes a control valve body to which oil is supplied from a main pump. The valve arrangement structure includes a pressure regulator valve that is arranged in the control valve body and regulates a pressure of discharged oil from the main pump to a line pressure, a pressure control valve that is arranged in the control valve body and regulates the pressure of the oil to a required pressure with the line pressure as a source pressure, and a first oil passage that is provided in the control valve body and connects the main pump and the pressure regulator valve. The pressure control valve is arranged on a second oil passage branched from the first oil passage.

Abstract: A machine can include an electric powertrain configured for electrical power and which includes a transmission. The transmission may be operatively associated with a hydraulic system that includes a hydraulic pump and a pressure relief valve disposed between the pump and the transmission. To reduce noise generated by the pressure relief valve, operation of the pressure relief valve may be regulated according to a pump function that relates operation of the pressure relief valve with a sensed pump operation associated with the hydraulic pump.

Abstract: A battery-temperature raising apparatus includes a battery, a transmission, an oil pan, a heat-retaining oil tank, a heat exchanger, a first valve, a temperature sensor, and a control unit. The transmission includes a transmission mechanism that converts torque and a clutch capable of braking a wheel. The oil pan and the oil tank are disposed in the transmission and are in communication with the heat exchanger that exchanges heat between the battery and oil. The first valve opens and closes a path joining the oil tank and the heat exchanger. The control unit generates braking force by controlling engagement force of the clutch depending on an amount of depression of a brake pedal. The control unit supplies the oil stored in the oil tank to the heat exchanger by opening the first valve when a temperature of the battery detected by the temperature sensor is below a predetermined temperature.
