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

[0038] see Figure 1 to Figure 4 , a method for controlling the quick-release throttle upshift delay of a dual-clutch transmission vehicle based on fuzzy control theory, comprising the following steps:

[0039] 1) Signal collection: The transmission control unit is used to collect accelerator, engine speed, foot brake signals, vehicle speed signals and handle position signals in real time. The engine control unit ECU transmits the throttle, engine speed and foot brake signals collected in real time to the transmission control unit TCU through CAN; the anti-lock braking system ABS transmits the vehicle speed signals collected in real time to TCU through CAN; at the same time, the electronic handle controller ESL transmits the handle position signal collected in real time to the transmission control unit TCU through CAN.

[0040] 2) Throttle slope calculation: the transmission control unit takes a differential of the throttle to obtain the throttle slope;

[0041] 3) Throttle ...

Abstract

The invention discloses a fuzzy-control-theory-based accelerator-quickly-released upshift-delay control method for an automatic gearbox vehicle. The accelerator-quickly-released upshift-delay controlmethod comprises the steps of gathering signals, calculating the accelerator slope, filtering the accelerator slope, calculating the accelerator-quickly-released upshift-delay slope, judging the accelerator-quickly-released upshift-delay and the like. According to the fuzzy-control-theory-based accelerator-quickly-released upshift-delay control method for the automatic gearbox vehicle, the accelerator-quickly-released upshift-delay slope is calculated utilizing the fuzzy control theory, whether the upshift is forbidden or not is judged according to the upshift-delay slope, the intention of drivers can be reflected more accurately, and the driving is made to be more comfortable.

Description

technical field [0001] The invention relates to the field of transmission control, in particular to an automatic transmission vehicle quick-release throttle upshift delay control method based on fuzzy control theory. Background technique [0002] Since the advent of dual-clutch transmissions, dual-clutch transmissions have become more and more mature, especially in recent years, major automobile or transmission parts suppliers are 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-clutch transmission is more convenient to use, because after all, it is still a manual transmissi...
