摘要： A transmission hydraulic control system includes a manual valve, a default valve, and a clutch prime valve. The manual valve allows fluid flow from a pressurized line to a drive line when the manual valve is open (when a transmission is in drive or reverse). The manual valve prevents fluid flow from the pressurized line to the drive line when the manual valve is closed (when the transmission is in neutral or park). The clutch prime valve allows fluid to flow from the pressurized line to the drive line, and thereby bypass the manual valve, when the manual valve is closed and the clutch prime valve is open. The default valve allows fluid bypassing the manual valve to flow to prime a clutch of the transmission when the default valve is open. The clutch prime valve prevents fluid from bypassing the manual valve when the clutch prime valve is closed.

摘要： An example system includes a processing resource and a switch board coupled to a system under test (SUT) and the processing resource. The SUT includes a memory device. The switch board can be configured to provide power to the SUT, communicate a first signal from the SUT to the processing resource, and provide a second signal to the SUT that simulates an input to the SUT during operation of the SUT. The processing resource can be configured to receive a function, selected from a library of functions, to execute during a test of the memory device and cause the switch board to provide the second signal during the test of the SUT.

摘要： A shift gearbox may include at least two driven piston-cylinder units, which are each driven via a transmission of a drive, and the piston-cylinder units may each comprise a piston, which delimits a working chamber, and each working chamber is in hydraulic connection with at least one clutch actuator and at least one gear selector via a hydraulic main line, whereby the clutch actuator comprises a working chamber delimited by a piston. A valve may be respectively arranged between each working chamber of a clutch actuator and a hydraulic main line, and both the pressure build-up and the pressure reduction in the clutch actuators may occur by adjusting the piston of a piston-cylinder unit.

摘要： The invention relates to an arrangement for reading off predetermined positions of a gear lever (11). A sensor arrangement (1) with a first sensor component (10) moves with the gear lever (11) and a plurality of second sensor components (S21-S25) interacts with the first sensor component (10), wherein in each of the predetermined positions of the gear lever (11), the first sensor component (10) interacts with at least one second sensor component (S21-S25). A position determination unit (30) compares the current sensor output values with stored sensor output values in a table (40). When a faulty condition is detected in one of the sensor components (S21-S25), the stored sensor output values for the faulty sensor component are updated with the faulty output value of the faulty sensor component in the table (40) of expected sensor output values.

摘要： A controller for a vehicle including a continuously variable transmission mechanism, a mechanical stepped transmission mechanism, and a drive wheel is provided. The controller includes an electronic control unit. The electronic control unit is configured to execute gear change control of the mechanical stepped transmission mechanism so as to establish any simulated gear stage of a plurality of simulated gear stages and to change a gear ratio of the continuously variable transmission mechanism stepwise. When determining that the mechanical stepped transmission mechanism has failed, the electronic control unit is configured to fix the mechanical stepped transmission mechanism at a limp-home mode mechanical gear stage, prohibit a stepped gear change of the continuously variable transmission mechanism, and change the gear ratio of the continuously variable transmission mechanism in a stepless manner on the basis of a vehicle state.

摘要： A shift position determination portion determines that operation of shifting a shift position from other range than a parking range to the parking range is conducted. A parking lock command portion causes a piston to maintain a state of being mechanically locked at a second position when the shift position is shifted to the parking range. An actuator drive command portion commands an actuator to drive the piston from the second position to a first position in a state where the position of the piston is mechanically locked at the second position. A parking lock failure determination portion determines that the locking mechanism portion is in a failure in an unlocked state when the position of the piston goes out of the second position within a predetermined time after a command is issued.
