Embodiment Construction

[0050] In order to enable those skilled in the art to further understand the features and technical contents of the present invention, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings and implementation methods.

[0051] like figure 1 It is a flow chart of a vehicle coasting shutdown fuel-saving control method according to an embodiment of the present invention, including the following steps:

[0052] Step 100: start.

[0053] Step 101: Detect whether the coasting stop function switch is turned on through the CAN bus; if yes, execute step 102; otherwise, execute step 111.

[0054] Of course, the electrical signal of the coasting stop function switch can also be directly detected to confirm whether the coasting stop function switch is turned on.

[0055] Step 102: Detect whether the system is faulty; if yes, execute step 111; otherwise, execute step 103.

[0056] Specifically, whether the detection system ...

Abstract

The invention relates to the technical field of vehicle fuel-saving control, in particular to a vehicle coasting and engine shutdown fuel-saving control method and system. The method comprises the steps that whether a coasting and engine shutdown function switch is switched on or not is detected through a CAN bus; if yes, whether a fault exists in the system or not is detected; if not, whether vehicle running safety conditions are met or not is detected; if yes, whether an operation intention of a driver meets the requirement or not is detected; if yes, whether road conditions are permissive or not is detected; if yes, a coasting and engine shutdown operation is performed; during coasting and engine shutdown, whether the operation intention of the driver changes or not, whether the vehicle running safety conditions change or not and whether the road conditions change or not are monitored in real time; if any one of the operation intention of the driver, the vehicle running safety conditions and the road conditions changes, power recovery operation is performed. By means of the vehicle coasting and engine shutdown fuel-saving control method and system, fuel is saved in the whole vehicle coasting process.

Description

technical field [0001] The invention relates to the technical field of vehicle fuel saving control, in particular to a fuel saving control method for vehicle coasting down. Background technique [0002] Due to the increasing emphasis on energy saving and environmental protection, the country’s corresponding passenger car fuel consumption regulations are also constantly updated and improved. "GB19578-2014 Passenger Car Fuel Consumption Limits" requires that vehicles newly announced in 2016 must meet the new fuel consumption standards , implemented on January 1, 2018 for vehicles in production, the fourth phase of the passenger car standard "GB27999-2014 Passenger Car Fuel Consumption Evaluation Method and Indicators" also requires the average fuel consumption of passenger cars to meet the requirements. For this reason, various OEMs are researching new fuel-saving technologies for complete vehicles, such as: idling start-stop function, shift reminder function, intelligent gene...
