The down shift controller comprises an engine 1, an automatic transmission 3, and an at controller 10.The at controller 10 is provided with a downshift gear shift processing section for performing a press down control by a release pressure control and a fastening element instruction when a ...
A downshift control in an automatic transmission is disclosed wherein magnitude of servo activating hydraulic fluid pressure is temporarily decreased as a function of vehicle speed when the automatic transmission effects a downshift from a current gear ratio to a new gear ratio. Owing to this arrange...
Are you facing problems while changing your gears to reverse or drive? If you have ever had a long pause between going in reverse and being able to slide into drive, then you understand the pain of a delayed shift. Most often, it is because of the transmission valve body that is working...
Automatic transmission control system and control method therefor upshift, and is set to a second predetermined range when the shift is a downshift, and- the second predetermined range is set to a range that a ... T Ikeda,H Kawakami 被引量: 0发表: 2018年 加载更多研究...
transmission output speed drops below a fifth predetermined downshift speed, the speed comparator 70 will provide a "lo" to the work/transport logic circuitry 72 which provides a "hi" to be delayed by the shift delay circuitry 96 and processed by the shift control logic circuitry 43 to cause...
But the automatic transmission is based on your throttle degree to decide whether you want to downshift, for example over the front of the train, you can release the accelerator and a foot down, then the gearbox will automatically drop 1 stalls and 2 stalls to meet your power requirements, ...
An improved control for an automatic transmission closed-throttle downshift, wherein closed-throttle engine torque is used to raise the transmission input speed to the synchronous speed of the target speed ratio, and wherein the on-coming clutch is controlled in a manner to complete the shift wit...
A downshift control device for an automatic transmission is provided in which a drive command is generated to a shift actuator when a shift command to change a gear ratio of the transmission is genera
Speed change ratio controller for stepless automatic transmission PURPOSE:To prevent a sudden increase, which is beyond the request of a driver, of driving force even in the downshift operation. CONSTITUTION:The shift in ... H Okahara 被引量: 4发表: 2001年 Speed change gear for automatic trans...
