Problems solved by technology

Because the calculation of the throttle slope is very simple, the throttle slope is the difference between the current throttle slope and the last throttle slope, and this control method only determines whether to prohibit upshifting based on the throttle slope, which makes the control method poorly adapted to the driver's intention, and there are Sometimes there will be situations contrary to the driver's intention

Embodiment Construction

[0042] see Figure 1 to Figure 4 , the computer program of the control method of the quick release and upshift delay function of the dual-clutch transmission vehicle based on fuzzy control theory in the present invention is installed and run in the transmission control unit TCU. Implement the functional module framework of the computer program of the control method of the upshift delay function of the quick loose throttle of the automatic transmission vehicle based on fuzzy control theory of the present invention is by signal acquisition module, throttle slope calculation module, throttle slope filter module, quick release The upshift delay slope calculation of the accelerator and the upshift delay judgment module of the quick release of the accelerator are composed.

[0043] The signal collection module is used for real-time collection of throttle signal, engine speed signal, foot brake signal, vehicle speed signal and handle position signal. see figure 1 , the engine contr...

Abstract

The invention discloses an urgently-releasing throttle upshifting delay control function module frame of an automatic transmission vehicle based on fuzzy control, and a transmission control system. The urgently-releasing throttle upshifting delay control function module frame comprises a signal acquisition function module, a throttle slope calculation function module, a throttle slope filter function module, an upshifting delay slope calculation function module of an urgently-releasing throttle, an upshifting delay judgment function module of the urgently-releasing throttle and the like. The upshifting delay slope of the urgently-releasing throttle is calculated by using a fuzzy control theory, whether upshifting is prohibited is judged according to the upshifting delay slope, the intention of a driver can be responded more accurately, and the driving and riding are more confortable.

Description

technical field [0001] The invention relates to the field of transmission control, in particular to a fuzzy control theory-based quick release throttle upshift delay control function module framework and a transmission control system of an automatic transmission vehicle. Background technique [0002] Since the advent of automatic transmissions, especially dual-clutch transmissions, dual-clutch transmissions have become more and more mature. Especially in recent years, major automobile or transmission parts suppliers have been increasing the research and development of dual-clutch transmissions. The dual-clutch transmission is different from the general automatic transmission. It is based on the manual transmission and is different from the automatic transmission. In addition to the flexibility of the manual transmission and the comfort of the dual-clutch transmission, it can also provide uninterrupted power output. Compared with the traditional manual transmission, the dual-...
