Problems solved by technology

The engine in the idling state runs as usual, but does not drive the car to move. At this time, the mechanical energy generated by gasoline combustion is consumed by the friction of internal parts, which consumes fuel and pollutes the environment.
[0004] In the process of realizing the present invention, the inventor has found that the prior art has at least the following problems: the control method of the prior art cannot solve the problem of vehicle idling

Embodiment 1

[0038] A control method for an automobile energy-saving control system, in which a vehicle speed signal, an accelerator signal, a neutral signal and a clutch pedal signal are obtained by an engine controller, if the vehicle speed signal obtained by the engine controller is greater than zero and less than or equal to the second trigger speed set value of 4km / h, and the engine controller also obtains the accelerator fully released signal, the neutral signal and the clutch pedal fully released signal at the same time, then controls the engine to stop automatically; otherwise, controls the engine to run as usual.

[0039] When the vehicle speed drops to 4km / h, if the accelerator is fully released, the neutral gear is engaged and the clutch pedal is fully released, it means that the driver has the intention to stop. At this time, the engine is controlled to stop automatically, so that the idling state of the car becomes an engine stagnation state. , Solve the situation of idling fu...

Embodiment 2

[0041] refer to figure 1 , a control method for an automobile energy-saving control system, the specific steps comprising:

[0042] (1) When the car key is turned to the ON gear and the car is ignited, the starter relay 15 is engaged, and the engine controller 1 obtains the signal of the starter relay 15 and the clutch action signal from the clutch bottom switch 13 or The neutral gear signal sent by the neutral gear switch 12, the engine controller 1 controls the normal start of the automobile engine 9, and the vehicle runs normally;

[0043] (2) The engine controller 1 obtains the signal that the vehicle speed reaches the first trigger speed setting value of 20km / h through the vehicle speed sensor 5, and obtains the no-air-conditioning request signal through the air-conditioning control switch 3, and the engine controller 1 controls the automobile to enter the energy-saving mode;

[0044] (3) In the energy-saving mode, the engine controller 1 obtains the signal that the vehi...

Embodiment 3

[0056] refer to figure 2 , the control equipment of the embodiment of the present invention includes an ignition switch 7, an engine 9, an engine controller 1, a starter relay 15 connected to the engine controller 1, a clutch bottom switch 13, a neutral switch 12, a vehicle speed sensor 5, an air-conditioning control switch 3, Accelerator pedal bottom switch 6 and starter 8. The ignition switch 7 is connected with the starter relay 15, and the ignition switch 7 controls the ignition of the vehicle; the starter relay 15 transmits a starting signal to the engine controller 1; the clutch bottom switch 13 transmits a clutch status signal to the engine controller 1; Transmit neutral signal; vehicle speed sensor 5 transmits vehicle speed signal to engine controller 1; air-conditioning control switch 3 transmits air-conditioning request signal or no air-conditioning request signal to engine controller; accelerator pedal bottom switch 6 transmits accelerator status signal to engine c...

Abstract

The invention discloses an automobile energy-saving control system which belongs to the field of automobile manufacturing. The control method of the automobile energy-saving control system comprises: an engine controller is used for acquiring a speed signal, a throttle signal, a neutral position signal and a clutch pedal signal; if the speed signal acquired by the engine controller is greater than zero and less than or equal to a second trigger speed setting value and the engine controller also simultaneously acquires a throttle complete release signal, the neutral position signal and a clutch pedal complete release signal, the engine is controlled to automatically stop; or else, the engine is controlled to run as usual. According to the invention, the defect of oil waste in the idle state during traveling at ordinary times can be solved by changing the idle state into the engine dead state, thus the goals of energy saving and emission reduction are realized.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automobile energy-saving control system. Background technique [0002] With the development of new technologies such as electronic technology, computer technology and information technology, electronic control systems have been more and more used in the field of automobile manufacturing. In the prior art, an engine controller is often used to control the operation of the automobile engine, thereby realizing optimal control of the automobile engine. [0003] In actual work, the car engine is often in an idling state. The so-called idling state refers to a working state when the engine is idling. When the engine is running, if the accelerator pedal is fully released, the engine is in idle state. The engine in the idle state runs as usual, but does not drive the car to move. At this time, the mechanical energy generated by gasoline combustion is consumed on the friction...
