[0069] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0070] In the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will appreciate that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit the difference. It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way. In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more.

[0071] It should be noted that the "at..." in the embodiment of the present application can be the instant when a certain situation occurs, or can be a period of time after the situation occurs, and the embodiment of the present application does not specifically limit this. In addition, the engine control method provided in the embodiment of the present application is only used as an example, and the engine control method can also include more or less content.

[0072] In order to clearly describe the technical solutions of the embodiments of the present application, some terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0073] Auto Hold function: is a driver assistance function designed to improve driving comfort and safety. The Auto Hold function can automatically start the electronic parking brake (i.e. automatically activate the vehicle's brake system) when the vehicle stops, maintain brake pressure, and keep the vehicle stationary without the driver having to keep pressing the brake pedal or using the handbrake. Therefore, when the vehicle's Auto Hold function is turned on, the vehicle will not move even if the driver releases the brake pedal. This function is particularly useful when stopping at traffic lights, in traffic jams, or starting on a slope, as it prevents the vehicle from sliding or moving unexpectedly, thereby improving driving safety and driving convenience. In addition, when the vehicle needs to start again, the driver only needs to lightly step on the accelerator pedal or press the release button, and the Auto Hold function will be turned off (i.e. automatically release the brake), allowing the vehicle to drive normally, so that the vehicle can move forward or backward smoothly.

[0074] The vehicle's automatic start-stop function is used to automatically shut down the engine when the vehicle is idling or parked, and quickly restart it when needed to save fuel and reduce exhaust emissions, thereby reducing environmental pollution.

[0075] Under current technical conditions, the vehicle's automatic start-stop function is particularly important when the vehicle is waiting for traffic lights or encountering traffic jams, because it can automatically shut down the engine when the vehicle stops briefly, and quickly restart the engine when the driver is ready to continue driving, thereby effectively avoiding unnecessary idling of the engine and reducing fuel consumption and greenhouse gas emissions when the vehicle is idling.

[0076] However, although the automatic start-stop function can reduce the vehicle's fuel consumption, the frequent restart of the engine in the traditional automatic start-stop system will have a negative impact on the vehicle's traffic efficiency and reduce the driver's driving comfort experience. For example, when the driver only needs to stop briefly at an intersection, or temporarily brakes due to the braking of the vehicle in front, after the vehicle's automatic start-stop function turns off the engine, the driver needs to quickly restart the engine in a short time before leaving the road section, thereby affecting the vehicle's traffic efficiency and the driver's driving comfort.

[0077] Based on this, the embodiments of the present application propose an engine control method, device, equipment, storage medium and program product, which can be used in the field of vehicle control technology, aiming to solve the above technical problems of the prior art. By accurately identifying the driver's parking intention and intelligently controlling the stopping and running of the engine according to this intention, it is ensured that the engine is started and stopped only at the right time, thereby improving the overall traffic efficiency of the vehicle and significantly improving the driving experience of the driver.

[0078] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0079] Figure 1 A schematic diagram of a process of an engine control method provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, the method includes:

[0080] S101. Obtain vehicle start-stop mode and automatic parking function status.

[0081] In the embodiment of the present application, the execution subject of an engine control method may be an electronic control unit (ECU) in a vehicle, which may be a controller specially designed for the engine control method, or may be an existing power control unit (PCU) or engine control unit in the vehicle, etc., without specific limitation. For the convenience of subsequent description, the execution subject of the engine control method is uniformly described as a controller in the embodiment of the present application.

[0082] Specifically, the vehicle start-stop mode includes at least two basic modes: a user autonomous control mode and an engine automatic start-stop mode. When the vehicle is in the user autonomous control mode, the controller can control the running state of the engine according to the stop command input by the user; when the vehicle is in the engine automatic start-stop mode, the controller can control the running state of the engine according to the vehicle automatic start-stop function in the prior art.

[0083] The automatic parking function status includes two states: on and off. When the vehicle's automatic parking function is on, the vehicle stops and the electronic parking brake is automatically activated; when the vehicle's automatic parking function is off, the vehicle will not automatically perform the parking brake or remain stationary, and the driver usually needs to actively operate the brake pedal or handbrake to keep the vehicle stationary.

[0084] S102: When the vehicle start-stop mode is the user autonomous control mode and the automatic parking function is in the on state, a parking ready message is displayed on a display device of the vehicle, and the vehicle enters the autonomous parking state.

[0085] In the embodiments of the present application, the user generally refers to the driver of the vehicle. The shutdown readiness information is used to prompt the user that the engine can be started and stopped autonomously. The display device of the vehicle can be a multi-function display screen on the instrument panel, a multimedia touch screen on the center console, a multi-function steering wheel button indicator light, a voice prompt system, a dedicated indicator light or a head-up display, etc., without specific limitation here.

[0086] Specifically, when the controller determines that the vehicle start-stop mode obtained is the user autonomous control mode and the automatic parking function state is turned on, the vehicle display device can display the parking readiness information to the user. The specific display method can be through a specific indicator light display, sound or voice prompt, or corresponding symbol or text message prompt, etc., to remind the user that the vehicle will enter the autonomous parking state at the same time.

[0087] S103: In the autonomous shutdown state, receiving a shutdown instruction from the user.

[0088] In the embodiment of the present application, the shutdown instruction includes at least one of the following: an operation instruction of a shutdown button on the vehicle, and a voice shutdown instruction.

[0089] Specifically, in the autonomous shutdown state, the user can send a shutdown command to the vehicle by manually controlling the steering wheel, the center console touch screen or the center console shutdown button, or by using the vehicle's voice control system. There are no specific restrictions here, thereby enabling the driver to control the engine to stop running or continue running according to road conditions and vehicle status.

[0090] S104. In response to the stop instruction, the current speed of the vehicle is detected in real time to start and stop the engine of the vehicle according to the current speed.

[0091] Specifically, after receiving the stop command input by the user, the controller can identify the driver's parking intention according to the stop command, and then detect the current speed of the vehicle in real time according to the driver's parking intention, and control the engine to stop or keep running according to the current speed of the vehicle.

[0092] The present embodiment provides an engine control method, which includes: first, obtaining a vehicle start-stop mode and an automatic parking function status; then, when the vehicle start-stop mode is a user autonomous control mode and the automatic parking function status is on, displaying a stop-ready message on a display device of the vehicle and entering an autonomous stop state, wherein the stop-ready message is used to prompt the user that the engine start-stop can be controlled autonomously; then, in the autonomous stop state, receiving a stop command from the user, wherein the stop command includes at least one of the following: an operation command of a stop button on the vehicle and a voice stop command; finally, in response to the stop command, detecting the current speed of the vehicle in real time to control the start-stop of the vehicle's engine according to the current speed.

[0093] The following technical effects are achieved: by obtaining the vehicle start-stop mode and the automatic parking function status, and when the vehicle start-stop mode is the user autonomous control mode and the automatic parking function status is on, the driver's parking intention is identified according to the user's stop command, and then the engine stop and operation are controlled according to the driver's parking intention and the current vehicle speed, ensuring that the engine is started and stopped only at the appropriate time, avoiding frequent restarts of the engine, thereby avoiding the negative impact of frequent restarts of the engine on the vehicle's traffic efficiency, improving the vehicle's traffic efficiency, and eliminating the need for the driver to frequently restart the engine in a short period of time, thereby improving the driver's driving experience.

[0094] Figure 2 A schematic diagram of a process of an engine control method provided in an embodiment of the present application Figure 2 In one possible example, Figure 2 As shown, in this embodiment Figure 1 Based on the embodiment, how to start and stop the engine of the vehicle according to the current vehicle speed is described in detail. Figure 2 As shown, the method includes:

[0095] S201. Display an interactive interface on a display device of a vehicle.

[0096] Specifically, the controller can display an interactive interface for interacting with the user through the vehicle's display device.

[0097] S202, receiving a first preset time length, a second preset time length, and a vehicle start-stop mode input by a user in an interactive interface.

[0098] Specifically, the user can input the corresponding first preset time, second preset time, and vehicle start-stop mode into the controller through the interactive interface. The first preset time refers to the maximum waiting time for the engine to not stop (i.e., keep running) when the vehicle is in an idling or parking state; the second preset time refers to the necessary time for the engine startup process to take place when the engine is restarted after it has stopped.

[0099] S203: Acquire the vehicle start-stop mode and automatic parking function status.

[0100] S204: When the vehicle start-stop mode is the user autonomous control mode and the automatic parking function is in the on state, a parking ready message is displayed on a display device of the vehicle, and the vehicle enters the autonomous parking state.

[0101] S205: In the autonomous shutdown state, receiving a shutdown instruction from the user.

[0102] S206 . In response to the shutdown instruction, detect the current speed of the vehicle in real time.

[0103] S203 - S206 are similar to S101 - S104 , and the same parts will not be described in detail in this embodiment.

[0104] S207: When the current vehicle speed is less than or equal to the preset vehicle speed, extract the remaining time of the red light, the number of waiting vehicles, and the traffic congestion from the road section information ahead.

[0105] Specifically, the preset vehicle speed can be set to 0 m / s, that is, the vehicle is in an idling or parking state. When the current vehicle speed is less than or equal to the preset vehicle speed, the controller can estimate the vehicle waiting time based on the road section information ahead, including:

[0106] The controller can obtain the vehicle's road ahead information in real time through the telematics box (TBox), global positioning system (GPS), satellite navigation system or high-precision map, etc. When the vehicle is detected to be idling or parked, the controller can extract the remaining time of the red light, the number of waiting vehicles, and the traffic congestion from the acquired road ahead information.

[0107] S208: Determine the passing time of a single vehicle according to the traffic congestion situation.

[0108] Specifically, the controller can determine the time it takes for a single vehicle to leave the congested road section based on the traffic congestion situation extracted from the road section information ahead.

[0109] S209: Calculate the congestion waiting time according to the number of waiting vehicles and the passing time of a single vehicle.

[0110] Specifically, the controller can use the product of the number of waiting vehicles ahead and the passing time of a single vehicle as the congestion waiting time.

[0111] S210: Determine the sum of the congestion waiting time and the remaining time of the red light as the vehicle waiting time.

[0112] Specifically, the controller may further sum the congestion waiting time and the remaining time of the red light to obtain the vehicle waiting time.

[0113] S211. When the waiting time of the vehicle is greater than or equal to a first preset time, obtain the battery power of the vehicle.

[0114] In the embodiment of the present application, the controller can control the engine to stop running when the vehicle waiting time is greater than or equal to the first preset time, specifically including:

[0115] When the waiting time of the vehicle is greater than or equal to the first preset time, the controller can obtain the battery power (State of Charge, SOC) of the vehicle from the battery management system (Battery Management System, BMS) through the communication network inside the vehicle.

[0116] S212: When the power level is greater than or equal to the preset power level, the engine is controlled to stop running.

[0117] In the embodiment of the present application, the preset power may refer to the battery power required for restarting the engine, such as 30% or 40%, etc., and is not specifically limited here. The specific preset power may be set comprehensively based on factors such as the engine type, displacement, number of cylinders, efficiency of the starter, battery status (such as newness, charge status, capacity, etc.), and starting conditions (such as cold start or hot start, normal temperature start or ultra-low temperature start).

[0118] Specifically, the controller can control the engine to stop running when the battery power of the vehicle is greater than or equal to a preset power, so as to save fuel and reduce emissions by controlling the engine to stop running when the vehicle is in an idling or parked state and the waiting time of the vehicle is greater than or equal to a first preset time.

[0119] S213: When the power level is less than the preset power level, control the engine to continue running.

[0120] Specifically, the controller can also control the engine to continue running when the vehicle's battery power is less than a preset power level, so as to charge the battery through the continuous operation of the engine, thereby maintaining the vehicle's power needs and ensuring that the vehicle has sufficient power to meet driving needs.

[0121] S214: When the current vehicle speed is greater than a preset vehicle speed and / or the vehicle waiting time is less than a first preset time, control the engine to continue running.

[0122] Specifically, when the controller detects that the vehicle is not in an idling or parked state, and / or the waiting time of the vehicle is less than a first preset time, the controller can determine that the vehicle is in a normal driving state and / or the vehicle is only parked for a short time, and the controller can control the engine to continue running, thereby avoiding frequent starting and stopping of the engine to affect the vehicle's traffic efficiency and the driver's driving experience, and avoiding frequent starting and stopping of the engine to cause wear on the engine and starting system.

[0123] S215: Determine the difference between the vehicle waiting time and the second preset time as the engine starting time.

[0124] Specifically, the second preset time is the time margin for starting the engine in advance. That is, when the vehicle is in an idling or parking state, and the waiting time of the vehicle is greater than or equal to the first preset time, and the battery power is greater than or equal to the preset power, the controller can control the engine to stop running. And after the engine stops running, the engine start time can be further determined. Specifically, the engine start time can be the difference between the vehicle waiting time and the second preset time (the necessary time taken by the engine start process).

[0125] S216: When the engine start time is reached, control the vehicle's engine to start.

[0126] Specifically, after the engine stops running, when the engine start time is reached, the controller can control the vehicle's engine to start in time, avoiding the delayed engine start caused by starting the engine after the vehicle has waited for a long time, which affects the vehicle's traffic efficiency, thereby further improving the vehicle's traffic efficiency.

[0127] An engine control method provided in an embodiment of the present application displays an interactive interface for interacting with a user through a display device of the vehicle, so that the user can set a first preset time, a second preset time and a vehicle start-stop mode; by controlling the engine to continue running when the battery power of the vehicle is less than the preset power, the battery is charged by the continuous operation of the engine, thereby maintaining the power demand of the vehicle and ensuring that the vehicle has sufficient power to meet driving needs; by controlling the engine to continue running when the vehicle is in a normal driving state and / or the vehicle is only stopped for a short time, the frequent start and stop of the engine is avoided to affect the vehicle's traffic efficiency and the driving experience of the driver, and the wear and tear of the engine and the starting system caused by the frequent start and stop of the engine is avoided; by controlling the vehicle's engine to start in time when the engine starts after the engine stops running, the delayed start of the engine caused by starting the engine after the vehicle has waited for a long time and affecting the vehicle's traffic efficiency, thereby further improving the vehicle's traffic efficiency.

[0128] The embodiment of the present invention can divide the electronic device or the main control device into functional modules according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing unit. The above integrated unit can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present invention is schematic and is only a logical function division. There may be other division methods in actual implementation.
