Embodiment Construction

[0027] The present invention will be further described below in conjunction with drawings and embodiments. The invention provides a control method for diesel engine idling start and stop, effectively utilizes ECU internal data and strategies, does not make any changes to ECU software, hardware and internal data, and does not need to make major changes to the original vehicle internal structure, the lowest The cost automatically realizes the start / stop control of the whole vehicle at idling speed, and achieves the purpose of saving fuel when the whole vehicle is running at idling speed.

[0028] It includes a start-stop controller that communicates with the ECU through the CAN bus to quickly obtain vehicle and engine information, and has the advantages of idling the vehicle to stop and starting quickly.

[0029] The start / stop control function is one of the main ways to avoid idling and low-efficiency areas during starting work, and to realize energy saving and cleanliness of a...

Abstract

The invention provides an idling start-stop controlling method for a diesel motor, which is characterized in that a start-stop controller connected to a finished automobile CAN (Controller Area Network) bus is adopted and is communicated with an engine ECU (Engine Control Unit) and a finished automobile electronic control part connected to the CAN bus through the CAN bus; when simultaneously meeting setting conditions, the start-stop controller controls an engine to enter an idling stopped state from an operating state; and when the engine is in the idling stopped state and a finished automobile simultaneously meets the setting conditions, the start-stop controller controls the engine to enter a starting state. In the idling start-stop controlling method, the finished automobile state is automatically identified and the idling start-stop process of the engine is automatically controlled by the start-stop controller without finished automobile modification and any operation of a driver.

Description

technical field [0001] The invention relates to an idle start-stop control method, in particular to an idle start-stop control method for a diesel engine. Background technique [0002] At present, the international crude oil price hits a record high, and the fuel price is also rising steadily. The society puts forward higher requirements on the fuel economy of automobiles, and various technical measures that can significantly reduce fuel consumption are highly valued by people. The application of new technologies and the rapid development of automobile intelligent technology have made the engine fuel consumption and emissions very low before leaving the factory. It is difficult to improve the engine performance alone. Therefore, some high-end vehicles use some fuel-saving devices. To save fuel, and these devices are expensive, it is difficult to popularize on ordinary cars. [0003] At present, the idling stop and start method is widely used in hybrid vehicles. For traditio...
