Description

Engine idle speed start-stop control method, system, device and storage medium

Technical Field

The present disclosure relates to the field of engine technologies, and in particular, to an engine idle speed start-stop control method, system, device, and storage medium.

Background

An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, and the like. The automobile engine is a device for providing power for an automobile, is the heart of the automobile and determines the power performance, economy, stability and environmental protection of the automobile.

In the related art, when an automobile runs on a crowded urban traffic road or encounters a traffic light, the automobile is stopped, waiting and then started, and the engine is in an idle state at this time, and the idle consumption of energy by the engine is meaningless. In order to avoid the waste of the energy sources, an engine idle start-stop technology is generally adopted, and the engine idle start-stop technology can automatically stop the engine to work when the vehicle is temporarily stopped based on the vehicle condition information such as the speed of the running vehicle, the position of an accelerator pedal, the position of a brake pedal, the position of a gear and the like, so that the fuel consumption is reduced, and the emission is reduced. When the traffic light is met, the driver only needs to apply the brake to stop the vehicle, the vehicle speed is lower than the minimum running vehicle speed at the moment, the engine automatically extinguishes, after the brake is released, the driver steps on the accelerator, and the engine is automatically started, so that the energy saving and emission reduction effects are achieved.

With respect to the related art in the above, the inventors found the following drawbacks: after the idle start-stop technology is adopted, the engine automatically extinguishes as long as a driver applies a brake to stop the vehicle, when the vehicle runs to a traffic light to wait for a red light, the waiting time of the red light of the traffic light is shorter, and the vehicle needs to be restarted just after being extinguished, so that the engine is quickly started after being extinguished, the service life of the engine is easy to be reduced, and the improvement space is provided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to fig. 1 to 8 and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

The embodiment of the application discloses an engine idle speed start-stop control method.

Referring to fig. 1, an engine idle start-stop control method includes:

step S100, obtaining actual information of idle start-stop pre-conditions.

The idle speed start-stop precondition actual information refers to actual condition information of various preconditions of a current vehicle when the idle speed start-stop is implemented, the idle speed start-stop precondition actual information comprises a vehicle speed value, an accelerator pedal position point, a brake pedal position point and a gear position point, the vehicle speed is detected and acquired through a speed detector preset on the current vehicle, the accelerator pedal position is detected and acquired through a distance detector arranged on the accelerator pedal, the brake pedal position point is detected and acquired through a distance detector arranged on the brake pedal, and the gear position point is detected and acquired through a distance detector arranged on the gear.

Step S200, judging whether the actual information of the idle start-stop precondition accords with the preset idle start-stop precondition datum information. If not, step S100 is executed, and if yes, step S300 is executed.

The idle start-stop precondition datum information refers to datum condition information of various preconditions of the current vehicle when the idle start-stop is implemented, and the idle start-stop precondition datum information is obtained by inquiring a database storing idle start-stop precondition datum information.

Judging whether the actual information of the idle start-stop preconditions accords with preset idle start-stop precondition reference information or not, so as to judge whether the actual condition information of each precondition of the current vehicle when idle start-stop is implemented accords with the reference condition information of each precondition of the current vehicle when idle start-stop is implemented, and further judge whether the current vehicle can execute idle start-stop.

When the actual information of the idle start-stop preconditions does not accord with the preset idle start-stop precondition reference information, the actual information of each precondition of the current vehicle when the idle start-stop is implemented is not accord with the reference information of each precondition of the current vehicle when the idle start-stop is implemented, and further, the current vehicle can not execute the idle start-stop, so that the step S100 is skipped.

Step S300, acquiring a real-time position point of the vehicle.

The real-time position point of the vehicle is the position point of the current vehicle at the current time, and is obtained through GPS query preset on the current vehicle.

Step S400, obtaining the final time of the red light waiting requirement corresponding to the latest traffic light position point according to the real-time position point inquiry of the vehicle.

The latest traffic light position point refers to the position point of the traffic light closest to the position point of the current vehicle at the current time, and the final time of the red light waiting requirement refers to the final time of the traffic light in the latest traffic light position point needing the current vehicle to wait at the current time.

The final time of the red light waiting requirement corresponding to the nearest traffic light position point is inquired and obtained through the real-time vehicle position point, so that the subsequent use of the final time of the red light waiting requirement is facilitated.

Step S500, judging whether the final time of the red light waiting requirement is smaller than the preset reference time of the red light waiting requirement. If yes, go to step S600; if not, step S700 is performed.

The red light waiting requirement reference time refers to the reference time that the traffic light in the nearest traffic light position point needs the current vehicle to wait at the current time, and the red light waiting requirement reference time is obtained by inquiring a database storing the red light waiting requirement reference time.

And judging whether the final time of the red light waiting requirement is smaller than the preset red light waiting requirement reference time or not, so as to judge whether the final time of the traffic light in the latest traffic light position point, which needs the current vehicle to wait at the current time, is smaller than the reference time of the traffic light in the latest traffic light position point, which needs the current vehicle to wait at the current time.

And S600, outputting preset idle speed start-stop disabling information, and sending the idle speed start-stop disabling information to an engine, an oil pump and a terminal held by a driver.

The idle speed start-stop disabling information is information for controlling the vehicle to disable the idle speed start-stop technology so that the engine is not automatically started after flameout, and the idle speed start-stop disabling information is obtained by inquiring a database storing the idle speed start-stop disabling information. The terminal held by the driver refers to a terminal which can receive and display idle start-stop disabling information, the terminal held by the driver can be a mobile phone, and the terminal held by the driver can also be a vehicle display screen.

When the final time of the red light waiting requirement is smaller than the preset standard time of the red light waiting requirement, the final time of the current vehicle waiting at the current time of the traffic light in the latest traffic light position point is smaller than the standard time of the current vehicle waiting at the current time of the traffic light in the latest traffic light position point, so that the red light waiting time of the traffic light is shorter, the vehicle does not execute the idling starting and stopping technology, and the service life of the engine is prolonged.

Step S700, executing a preset idle start-stop operation reference scheme.

The idle speed start-stop operation reference scheme is information for controlling a vehicle to use an idle speed start-stop technology, and is obtained by inquiring a database storing the idle speed start-stop operation reference scheme.

When the final time of the red light waiting requirement is not less than the preset red light waiting requirement reference time, the final time of the current vehicle waiting at the current time of the traffic light in the latest traffic light position point is not less than the reference time of the current vehicle waiting at the current time of the traffic light in the latest traffic light position point, so that the red light waiting time of the traffic light is longer, the vehicle is enabled to execute the idling starting and stopping technology, the fuel consumption is reduced, and the emission is reduced.

In step S400 shown in fig. 1, in order to further ensure the reasonability of the red light waiting requirement end time, further separate analysis calculation of the red light waiting requirement end time is required, specifically, the detailed description will be given by the steps shown in fig. 2.

Referring to fig. 2, the final time of obtaining the red light waiting requirement corresponding to the latest traffic light position point according to the real-time position point query of the vehicle includes the following steps:

Step S410, analyzing and acquiring the nearest traffic light position point corresponding to the real-time position point of the vehicle according to the corresponding relation between the real-time position point of the vehicle and the preset nearest traffic light position point.

The nearest traffic light position point is obtained through real-time position point analysis of the vehicle, so that the nearest traffic light position point is convenient to use subsequently.

Step S420, according to the corresponding relation between the latest traffic light position point and the preset current red light waiting demand time, analyzing and obtaining the current red light waiting demand time corresponding to the latest traffic light position point.

The current red light waiting requirement time refers to the actual time that the traffic light in the latest traffic light position point needs the current vehicle to wait at the current time, and the current red light waiting requirement time is inquired and obtained from a database storing the current red light waiting requirement time.

The current red light waiting demand time is obtained through the analysis of the nearest traffic light position point, so that the current red light waiting demand time is convenient to use subsequently.

Step S430, according to the real-time position point of the vehicle and the position point of the nearest traffic light, the distance value between the real-time position point of the vehicle and the position point of the nearest traffic light is analyzed and calculated and is used as the actual distance value of the traffic light.

The actual distance value of the traffic light of the vehicle refers to an actual distance value between a position point of the current vehicle at the current time and a position point of the traffic light nearest to the position point of the current vehicle at the current time.

The distance value between the real-time vehicle position point and the nearest traffic light position point is analyzed and calculated through the real-time vehicle position point and the nearest traffic light position point, and the distance value between the real-time vehicle position point and the nearest traffic light position point is used as the actual vehicle traffic light distance value, so that the subsequent use of the actual vehicle traffic light distance value is facilitated.

Step S440, judging whether the actual distance value of the vehicle red and green lights is smaller than the preset distance reference value of the vehicle traffic lights. If yes, go to step S450; if not, step S460 is performed.

The vehicle traffic light distance reference value refers to a reference distance value between a position point of a current vehicle at the current time and a position point of a traffic light nearest to the position point of the current vehicle at the current time, and is obtained by inquiring a database storing the vehicle traffic light distance reference value.

And judging whether the actual distance value of the traffic light is smaller than a preset traffic light distance reference value or not, so as to judge whether the actual distance value between the current vehicle position point at the current time and the traffic light position point closest to the current vehicle position point at the current time is smaller than the reference distance value between the current vehicle position point at the current time and the traffic light position point closest to the current vehicle position point at the current time or not.

In step S450, the current red light waiting requirement time is used as the red light waiting requirement final time.

When the actual value of the traffic light distance of the vehicle is smaller than the preset traffic light distance reference value, the actual distance value between the position point of the current vehicle at the current time and the position point of the traffic light closest to the position point of the current vehicle at the current time is smaller than the reference distance value between the position point of the current vehicle at the current time and the position point of the traffic light closest to the position point of the current vehicle at the current time, so that the current red light waiting requirement time is used as the red light waiting requirement final time, and the accuracy of the acquired red light waiting requirement final time is improved.
