Embodiment Construction

[0038] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be noted that this embodiment is illustrative rather than restrictive, and does not limit the scope of protection of the present invention.

[0039] The present invention is an optimal idling start-stop system based on an online algorithm. The system includes: a central processing module 1 , a power supply module 2 , a data acquisition module 3 , a communication module 4 and a driving module 5 .

[0040]The central processing unit module 1 is responsible for collecting the signal of the vehicle state parameter, and exchanging data with other control units through the data bus. The closed state is still in the open state, and the command for controlling the engine to be turned on and off is transmitted to the ESM starter module and the solenoid valve drive circuit module.

[0041] The block diagram of the central processing u...

Abstract

The invention relates to an idling start and stop system based on online algorithm optimization. The system comprises a central processing module (1), a power supply module (2), a data acquiring module (3), a communication module (4) and a driving module (5), and is characterized in that the central processing module (1) is responsible for acquiring signals of vehicle state parameters, exchanges data with the data acquiring module (3), the communication module (4) and the driving module (5) through a data bus, and analyzes switch signals and simulation signals of the vehicle state parameters based on an online algorithm to determine if a vehicle engine is located in a closing state or an opening state so as to send an instruction of controlling opening or closing of the engine to a ESM starter module and an electromagnetic valve driving circuit module. Before the idling start and stop system is operated, the idling start and stop are prejudged, so that the operation frequency of the system is reduced, and the control confusion of the idling start and stop system is reduced.

Description

technical field [0001] The invention belongs to the technical field of engine idle speed control, and in particular relates to an optimal idle speed start-stop system based on an online algorithm. Background technique [0002] With the increasing number of automobiles in my country (about 20 million sales per year), the fossil energy consumed by automobiles is increasing day by day, and at the same time, a large amount of pollutants are emitted, which has caused serious pollution to the atmospheric environment. In order to increase environmental protection and reduce energy consumption, emission standards have been gradually increased, such as the National VI emission policy to be released in the future. China VI has not yet given a specific definition, but it can be seen from the development of the Euro V standard to the Euro VI standard that the emission limit of nitrogen oxides has been reduced from 2g / kWh to 0.4g / kWh. With the rapid increase of urban vehicles, traffic c...
