Problems solved by technology

[0002] Automatic transmissions are becoming more and more popular. In order to improve the driving pleasure of automatic transmissions and retain the driving style of manual transmissions, automatic transmissions need to develop the function of manual integration. CVT automatic transmissions are continuously variable automatic transmissions. There is no AT fixed gear ratio. In order to simulate a manual transmission, the CVT needs to divide the continuous speed ratio into several estimated speed ratios to simulate stepped shifting. The manual mode with shift paddles can create a sporty atmosphere and improve the driving pleasure of the CVT. However, the existing technology does not There is no intelligent control method for CVT manual mode with paddle shifters that takes into account the actual driving situation

Embodiment Construction

[0034] The present invention will be clearly and completely described below in conjunction with the accompanying drawings and embodiments, and the technical problems and beneficial effects solved by the technical solutions of the present invention are also described. It should be pointed out that the described embodiments are only intended to facilitate the implementation of the present invention understood without any limitation.

[0035] The CVT automatic transmission manual mode control system with shift paddles of the present invention includes a shifter controller, an engine controller and a transmission controller, and the shifter controller collects the gear position PRND signal operated by the driver and the driving mode Signals such as switching and shifting paddles, and send the signals to the CAN bus, the engine controller controls the engine body, outputs power, and at the same time sends related signals such as engine speed, accelerator pedal, and brake signals to ...

Abstract

The invention discloses a method for controlling a manual mode of an automatic transmission with a gear shifting piece. By setting manual mode entry condition and manual mode exit condition, when manual mode activation flag bit is TRUE, upshift, downshift or skip control is carried out on current gear through comprehensive judgment, and engine is made to work within effective engine rotating speedrange. By means of the manual mode control method, manual mode switching of the CVT can be achieved, drivability is improved, hardware cost does not need to be increased, even if a driver suddenly overtakes a full accelerator, a transmission controller can automatically recognize and automatically skip to shift gears, and driving pleasure and driving safety are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automatic transmission control of automobiles, relates to the manual-automatic integration technology of an automatic transmission, and in particular relates to a manual mode control method of an automatic transmission with shift paddles.
