Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing.

[0034] Such as figure 1 As shown, the three-in-one intelligent control of idling fine-tuning, PTO and cruise control shares a set of four self-resetting switches, and activates and operates one of the functions according to the different working conditions of the diesel engine and the vehicle as well as the driver's intention, and the three functions The activation condition judgment and control process mainly include the following steps:

[0035] (1) The ECU first processes the signals such as the current speed of the diesel engine, the current speed of the vehicle and other switch inputs;

[0036] (2) According to the above parameters, it is judged whether the activation condition of constant speed cruise is satisfied, if the result is yes, then perform step (3), if the result is no, then perform step (8);

[0037] (3) When the constant speed cruise activation condition...

Abstract

The invention relates to an idle speed minor adjustment, PTO and cruise control intelligent control method of an electric control diesel engine. The method is characterized in that the idle speed minor adjustment, PTO and cruise control intelligent control method totally uses a group of self-reset switches which contain four switches and any one function can be activated and controlled according to different working conditions of the diesel engine or other vehicles and the intention of the driver. Compared with the prior art, the invention has the advantages of convenient operation and lower cost.

Description

technical field [0001] The invention relates to a diesel engine and its control system, in particular to a three-in-one intelligent control method for electronically controlled diesel engine idling fine-tuning, PTO and cruise control. Background technique [0002] The idle speed fine-tuning function allows the driver to manually adjust the target idle speed through the switch on the instrument panel when the diesel engine is at idle speed; the power output PTO (Power Take Off) function allows the driver to control the diesel engine below a certain speed through the switch. Enter the fixed speed operation mode to meet the power output requirements other than the wheels; when the car is driving on a long-distance expressway, start the cruise control function to automatically fix the vehicle at a specific speed, eliminating the need for drivers to pedal for a long time Throttle pain. [0003] At present, the above three functions are realized in the diesel engine through the e...
