A vehicle transmission has a continuously variable speed change mechanism provided between an input shaft to which a torque output by a driving force source is transmitted and an output shaft from which a torque is output to a driving wheel. The transmission is able to selectively block torque transmission between the mechanism and the output shaft. The mechanism is rotated by the driving force source with torque transmission between the mechanism and the output shaft blocked. A control apparatus limits a shifting speed of the mechanism to or below an upper-limit speed determined in advance in a case where a speed ratio of the mechanism is changed with the mechanism rotated by the driving force source that is subjected to idling rotational speed control, while the mechanism is blocked from the output shaft such that no torque is transmitted between the mechanism and the output shaft.

The present invention discloses an ultra-deep and extra-thick dense sand stratum prestressed pipe pile long spiral lead hole construction method. The method comprises the following steps of: S1: siteformation and drill stem equipping: performing leveling and compaction for a site prior to place taking, or bedding a steel plate to facilitate place taking of a pile machine, and regulating equippingof the corresponding quantity of drill stems according to the depth of the lead holes to ensure the lead hole operation flow construction, wherein two lead hole drills are arranged on the site; and S2: location, paying-off and place taking of the pile machine: employing a total station to perform laying-off for preset lead hole stake positions, taking a drill machine in place to complete correction of the vertical degree of the drill stem and the centering of the center of the drill, and after location, putting down a support oil cylinder at the lower portion of a front-end mast and two support oil cylinders at the tail portion of the machine body of the drill machine. The ultra-deep and extra-thick dense sand stratum prestressed pipe pile long spiral lead hole construction method can extend the drill stem at will through connection according to pore-forming demands by employing a design of the hexagonal joint of the drill stem, can effectively ensure the reliable connection of the drill stem by only using a dual-way fixed plug pin after the drill stem is inserted when being connected and can meet the construction of an overlength pile hole.

The present invention discloses a clutch control method and a terminal, which control the quick disengagement of the clutch at a first preset speed; perform gear shifting according to the received target gear; and control the quick closing of the clutch to a half-clutch position at the first preset speed ; Control the clutch to advance toward the target engagement position at a low speed at a second preset speed. During the low-speed propulsion process, calculate the clutch slippage in real time. When the clutch slippage is less than a preset value, use the first preset Set the speed to control the clutch to quickly engage to the target engagement position; during the clutch engagement process, at the beginning and end stages, the clutch is quickly engaged to reduce the clutch movement time in the whole process, and the clutch is half-engaged to stably control the clutch to make the vehicle speed and rotation speed match stably , so as to make the vehicle run stably. Through the fast and stable clutch control, the stability and comfort of starting can be realized, the situation of stalling at the start can be avoided, and the starting quality can be fully improved. The fast and reliable control of the clutch can increase the shifting speed.

The invention relates to a vehicle automatic synchronous shift device, which is characterized in that: it comprises a speed variable device, an engine, and a clutch as the controlled system, and an electric controller and variable sensors. The frame of engine flywheel is fixed with an open electromagnetic brake; therefore, the automatic shift device controlled by microprocessor can shift without separating the clutch. The invention can improve the shift speed to reduce the impact of clutch most. Therefore, the clutch can avoid be replaced in the whole life of vehicle.

An electronic device includes a detector configured to detect a user input and a controller configured to determine a favorite channel group according to a user's viewing history, scan channels in response to detecting an input of a control signal corresponding to a channel shift button for a predetermined time, and decrease a channel shift speed in a favorite channel group section corresponding to the determined favorite channel group and increase the channel shift speed in a section other than the favorite channel group section.

A precise control method for a buffer oil cylinder, the signal output terminals of the high-grade micro switch and the low-grade micro switch are connected to the signal input terminal signal of the servo drive, and the signal output terminal of the servo drive is connected to the control terminal signal of the servo motor connected, the signal output end of the motor encoder of the servo motor is connected to the signal of the servo driver, the signal of the servo driver is connected to the controller, and the signal of the controller is connected to the signal output end of the speed sensor provided on the load; including the second Step 1: Acquisition of load speed and sending of control commands, Step 2: PID control of servo motor rotation, Step 3: Switch feedback control, Step 4: Complete gear switching. This design is not only fast in shifting speed, but also good in reliability and high in shifting precision.

The present application discloses a method and device for adjusting the torque of a vehicle. The vehicle includes a first power source and a second power source. The method includes: obtaining the first torque output by the first power source; if the first torque is greater than the first power If the maximum torque output by the source is determined, the torque change rate of the second power source is determined to be the first rate; if the first torque is less than or equal to the maximum torque output by the first power source, then the torque change rate of the second power source is determined to be the second rate. rate; where the first rate is less than the second rate. That is, when the first torque output by the first power source has not reached the maximum torque output by the first power source, the rate of change of the torque output by the second power source is accelerated to increase the shifting speed; When the first torque reaches the maximum torque output by the first power source, the rate of change of the output torque of the second power source is slowed down to optimize the driving comfort, which can ensure the driving comfort of the vehicle under the premise of appropriate shift time.
