Embodiment Construction

[0026] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0027] In a preferred embodiment, a vehicle engine start-stop control technology is mainly applied to vehicles equipped with manual transmissions. Compared with traditional vehicles, a neutral switch sensor, a bottom clutch sensor, and a high-efficiency generator are replaced. Starter and battery etc. In the case of red lights such as traffic congestion and long-term idling, when the set start-stop control conditions are met, the engine is automatically turned off and started. Compared with traditional vehicles that are not equipped with start-stop functions, this technology can reduce the fuel consumption of the vehicle by about 0.3 -0.5L / 100Km. As the technology continues to mature, more models will be equipped with it.

Abstract

The invention relates to an automobile engine idle speed starting and stopping control method and device. The device comprises an automobile ECU, a gearbox neutral position switch sensor and a bottom on-off switch sensor, wherein engine idle speed starting and stopping control logics are integrated inside the automobile ECU; and the gearbox neutral position switch sensor and the bottom on-off switch sensor are used for judging the state of an automobile transmission chain, are in communication connection with the automobile ECU and transmit signals to the automobile ECU. Under the condition of ensuring safety of an automobile, an engine is automatically controlled to stop, energy emissions are reduced, the automobile idle speed oil consumption is reduced, and the engine is controlled to start or stop under the idle speed and traffic jam working conditions so as to reduce the automobile energy consumption.

Description

technical field [0001] The invention relates to an engine control technology in the automobile industry, which is mainly applied to a vehicle equipped with a manual gearbox, and specifically relates to a control method for idling start and stop of an automobile engine and a control device thereof. Background technique [0002] With the rapid development of the automobile industry, household and commercial vehicles are becoming more and more common in people's daily life and work. All automobile manufacturers at home and abroad are committed to improving the engine system, transmission system, engine gearbox matching, engine electronic control system and gearbox electronic control system, in order to achieve the best working condition of the whole vehicle, and then improve the fuel economy of the vehicle . Such as turbocharged engine, electric power steering, 48V system, etc. [0003] On the basis of manual transmission models, the present invention adds engine start-stop c...
