摘要： In a hydromechanical transmission, low and high range clutches are selectively operated in response to variation of an actual speed ratio between an input shaft and an output shaft to complete low or high speed drive power train. The transmission comprises a speed ratio detecting valve for detecting lower and higher limits of a predetermined speed ratio and a clutch control valve for selectively operating the low and high range clutches when the actual speed ratio reaches in a range defined by the lower and higher limits of the predetermined speed ratio. The operation of the clutch control valve is controlled by a pressure control valve in accordance with a difference in value between a first signal responsive to a throttle opening angle and a second signal responsive to the rotation speed of the input shaft such that the low and high range clutches are selectively operated only when the difference between the first and second signals becomes a predetermined value.

摘要： A speed ratio control system for a stepless variable speed transmission of vehicles having an electronic fuel injection control system. A speed ratio control signal for controlling the speed ratio of the stepless variable speed transmission is produced from the output fuel injection control signal from the electronic fuel injection control system and a target fuel injection quantity signal from an electronic arithmetic unit which generates the target fuel injection quantity signal in response to a throttle opening indication signal. The output fuel injection control signal is compared with the target fuel injection quantity signal to generate the speed ratio control signal which controls the speed ratio of the stepless variable speed transmission until the fuel injection indicated by the fuel injection from the electronic fuel injection system becomes equal to the target fuel injection quantity.
