[0002] As vehicle fuel consumption requirements become increasingly stringent, more and more vehicles in the current market are equipped with a start-stop system. The start-stop system is designed to shut down the engine when the vehicle is idling, reducing fuel consumption and carbon dioxide emissions when the engine is idling.

[0003] In the prior art, a camera is used to identify the status of the traffic light in the lane where the vehicle is located, and the engine status is controlled according to the traffic light status, that is, when the traffic light status is red, the engine is controlled to enter a stopped state; when the traffic light status is green, the engine is controlled to enter a running state.

[0004] However, when there is no traffic light in front of the vehicle or the traffic light is blocked, the camera cannot identify the status of the traffic light, resulting in the inability to determine the starting timing of the engine in a stopped state; in addition, when the current road condition is congested, the start-stop system will control the engine to start and stop frequently, reducing the user's driving comfort. Summary of the invention

[0029] Figure 1 This is a flow chart of an engine start-stop control method provided by an embodiment of the present application. This embodiment can be applied to a scenario where the engine is in a stopped state and it is necessary to determine the engine start timing and use the start-stop system to start the engine. The engine start-stop control method provided by this embodiment can be executed by the engine start-stop control device provided by an embodiment of the present application, and the device can be implemented by software and / or hardware. In a specific embodiment, the engine start-stop control device can be integrated in a vehicle. The execution subject of this method can be the vehicle controller of the vehicle, see Figure 1 The engine start-stop control method of this embodiment includes but is not limited to the following steps:

[0030] S110: Monitor the status of the vehicle ahead.

[0031] The front vehicle is a vehicle located in front of the current vehicle.

[0032] Specifically, when the engine of the current vehicle is in a stopped state, the state of the vehicle ahead can be monitored in real time, that is, whether the vehicle ahead is stationary or moving, to determine whether the state of the vehicle ahead has changed. For example, a high-frequency radar (such as millimeter wave), infrared laser radar, or camera can be used to monitor the state of the vehicle ahead in real time.

[0033] S120: Determine whether the vehicle ahead has changed from a stationary state to a moving state.

[0034] Specifically, when monitoring the state of the vehicle ahead, it is determined in real time whether the state of the vehicle ahead changes to determine whether the vehicle ahead changes from a stationary state to a driving state. If the vehicle ahead changes from a stationary state to a driving state, S130 is executed to obtain the driving parameters of the vehicle ahead; if the vehicle ahead does not change from a stationary state to a driving state, S110 is executed to continue to monitor the state of the vehicle ahead in real time.

[0035] S130: When it is detected that the vehicle ahead changes from a stationary state to a driving state, the driving parameters of the vehicle ahead are obtained.

[0036] The driving parameters are relevant information of the vehicle ahead when driving, and may include information such as driving distance.

[0037] Specifically, when the front vehicle changes from a stationary state to a driving state, the driving parameters of the front vehicle can be obtained. For example, the high-frequency radar (such as millimeter wave), infrared laser radar or camera of the current vehicle can be used to monitor the front vehicle in real time to obtain the relative distance between the front vehicle and the current vehicle or the driving distance of the front vehicle within a preset time. Among them, the preset time is a preset value used to determine whether the front vehicle will not stop in a short time. The user can adjust and set the preset time according to actual use needs, and the embodiment of the present application does not make specific limitations on this.

[0038] S140: Determine whether the driving parameters of the vehicle ahead meet the preset starting conditions of the current vehicle.

[0039] The preset start condition is a pre-set judgment condition used to determine the start time of the engine of the current vehicle. The user can adjust and set the preset start condition according to actual use requirements, and the embodiment of the present application does not specifically limit this. For example, the preset start condition can be that the relative distance between the front vehicle and the current vehicle is greater than the preset relative distance.

[0040] The preset relative distance is a preset distance value used to determine whether the relative distance between the front vehicle and the current vehicle meets the preset start condition. The user can adjust and set the preset relative distance according to actual use requirements, and the embodiment of the present application does not specifically limit this. For example, the preset relative distance can be 2 meters.

[0041] Specifically, after obtaining the driving parameters of the vehicle in front, it can be determined whether the driving parameters of the vehicle in front meet the preset starting conditions of the current vehicle. For example, it can be determined whether the relative distance between the vehicle in front and the current vehicle is greater than the preset relative distance. If the relative distance between the vehicle in front and the current vehicle is greater than the preset relative distance, it indicates that the driving parameters of the vehicle in front meet the preset starting conditions of the current vehicle. In this case, S150 is executed to start the engine of the current vehicle. If the relative distance between the vehicle in front and the current vehicle is less than or equal to the preset relative distance, it indicates that the driving parameters of the vehicle in front do not meet the preset starting conditions of the current vehicle. In this case, S130 is executed to continue to monitor the vehicle in front in real time to obtain the driving parameters of the vehicle in front in real time.

[0042] S150: When the driving parameters of the front vehicle meet the preset starting conditions of the current vehicle, start the engine of the current vehicle through the start-stop system of the current vehicle.

[0043] Among them, the start-stop system is used to control the starting and stopping of the engine, that is: when the vehicle needs to stop temporarily during driving, the start-stop system automatically controls the engine to stop; when it needs to continue moving forward, the start-stop system automatically starts the engine.

[0044] Specifically, when the driving parameters of the vehicle ahead meet the preset start conditions of the current vehicle, it indicates that the vehicle ahead is in a driving state and will not stop in a short time. At this time, the start-stop system of the current vehicle can be used to start the engine of the current vehicle so that the engine of the current vehicle is in a running state. For example, when the driving parameters of the vehicle ahead meet the preset start conditions of the current vehicle, an engine start instruction can be generated, and the engine start instruction can be sent to the start-stop system through the controller area network (CAN) bus, after which the start-stop system can receive the engine start instruction and control the engine start of the current vehicle. Among them, the engine start instruction is a command for notifying the start-stop system to control the engine start.

[0045] According to the technical solution of the embodiment of the present application, the current vehicle can monitor the state of the vehicle in front; determine whether the vehicle in front is changing from a stationary state to a driving state; when it is monitored that the vehicle in front is changing from a stationary state to a driving state, obtain the driving parameters of the vehicle in front; determine whether the driving parameters of the vehicle in front meet the preset starting conditions of the current vehicle; when the driving parameters of the vehicle in front meet the preset starting conditions of the current vehicle, start the engine of the current vehicle through the start-stop system of the current vehicle. In the above technical solution, the state of the vehicle ahead can be monitored in real time, and when the vehicle ahead changes from a stationary state to a driving state, the driving parameters of the vehicle ahead are obtained in real time, and it is determined whether the driving parameters of the vehicle ahead meet the preset start conditions of the current vehicle. If the driving parameters of the vehicle ahead meet the preset start conditions of the current vehicle, the engine of the current vehicle is started by the start-stop system of the current vehicle; if the driving parameters of the vehicle ahead do not meet the preset start conditions of the current vehicle, the vehicle ahead is continuously monitored in real time to obtain the driving parameters of the vehicle ahead in real time, and the start timing of the engine of the current vehicle is determined by the state and driving parameters of the vehicle ahead, so as to realize the start-stop control of the engine, optimize the start timing of the engine, improve the accuracy of the start-stop control of the engine, reduce fuel consumption and carbon dioxide emissions, and solve the problem of being unable to determine the start timing of the engine due to the absence of a signal light or the signal light being blocked ahead; when the driving parameters of the vehicle ahead meet the preset start conditions of the current vehicle, the engine is started by using the start-stop system, which effectively avoids frequent start-stop of the engine, solves the problem of frequent start-stop of the engine in congested road conditions, thereby improving the driving comfort of the user, reducing the wear of the engine, and extending the service life of the engine.

[0046] The following further describes an engine start-stop control method provided by an embodiment of the present application. Figure 2 is another flow chart of an engine start-stop control method provided by an embodiment of the present application. The present application embodiment is optimized based on the above embodiments. Figure 2 The engine start-stop control method of this embodiment includes but is not limited to the following steps:

[0047] S210: Control the engine of the current vehicle to stop according to a stop instruction from the user.

[0048] The stop instruction is a stop instruction determined according to the user's driving behavior, indicating that the user intends to stop.

[0049] Specifically, the user's parking intention can be determined based on the user's driving behavior, that is, the brake pedal opening sensor can be used to obtain the opening of the brake pedal, and determine whether the opening of the brake pedal is greater than zero to determine whether the user has the intention to park. If the opening of the brake pedal is greater than zero, it indicates that the user has the intention to park. At this time, the opening of the brake pedal is the user's stop command. After that, the engine speed of the current vehicle can be controlled to zero according to the user's stop command to control the engine of the current vehicle to stop; if the opening of the brake pedal is equal to zero, it indicates that the user has no intention to park. At this time, the brake pedal opening sensor can continue to be used to obtain the opening of the brake pedal to monitor the user's parking intention in real time.

[0050] After the engine of the current vehicle is controlled to stop, the engine is in a stop state, and then S230 may be executed.

[0051] S220: Controlling the engine of the current vehicle to stop by using the start-stop system of the current vehicle.

[0052] Specifically, when the current vehicle is in an idle state, the engine of the current vehicle can be controlled to stop by the start-stop system of the current vehicle, that is, when the current vehicle is in an idle state, an engine stop command can be generated, and the engine stop command can be sent to the start-stop system through the CAN bus, after which the start-stop system can receive the engine stop command and control the engine speed of the current vehicle to zero to control the engine of the current vehicle to stop. Among them, the idle state refers to the state where the opening of the accelerator pedal is zero, at which time the engine only maintains basic operation to drive the vehicle's accessory systems, such as the cooling system and the power supply system. The engine stop command is a command used to notify the start-stop system to control the engine to stop.

[0053] After the engine of the current vehicle is controlled to stop, the engine is in a stop state, and then S230 may be executed.

[0054] It should be noted that when it is necessary to control the engine to stop according to the user's parking intention, S210 is executed; when the current vehicle is in idle state, S220 is executed; S210 and S220 are in a parallel relationship, and there is no obvious order of execution. The execution order can be determined according to actual conditions, and this embodiment does not make specific limitations on this.

[0055] S230: When the engine of the current vehicle is in a stopped state, determine whether there is a target vehicle directly in front of the current vehicle.

[0056] The target vehicle is a stationary vehicle within a first preset distance directly in front of the current vehicle, and directly in front of the current vehicle refers to a vehicle in front of the current vehicle and in the same lane as the current vehicle.

[0057] The first preset distance is a preset distance value used to determine whether there is a stationary vehicle directly in front of the current vehicle. The user can adjust and set the first preset distance according to actual use requirements, and the embodiment of the present application does not specifically limit this. For example, the first preset distance can be 8 meters.

[0058] Specifically, when the engine of the current vehicle is in a stopped state, a high-frequency radar (such as millimeter wave), an infrared laser radar or a camera and other equipment can be used to monitor the front of the current vehicle in real time to determine whether there is a stationary vehicle within a first preset distance in front of the current vehicle, so as to determine whether there is a target vehicle in front of the current vehicle. If there is a stationary vehicle within the first preset distance in front of the current vehicle, it indicates that there is a target vehicle in front of the current vehicle. At this time, S240 is executed to monitor the status of the target vehicle in real time; if there is no stationary vehicle within the first preset distance in front of the current vehicle, it indicates that there is no target vehicle in front of the current vehicle. At this time, the front of the current vehicle can continue to be monitored in real time to determine whether there is a target vehicle in front of the current vehicle.

[0059] S240: When there is a target vehicle directly in front of the current vehicle, monitor the status of the target vehicle.

[0060] Specifically, when there is a target vehicle directly in front of the current vehicle, high-frequency radar (such as millimeter wave), infrared laser radar or camera and other equipment can be used to monitor the status of the target vehicle in real time.

[0061] Furthermore, the image or video of the target vehicle can be collected by a camera; the image or video can be analyzed to determine the state of the target vehicle. That is, the target vehicle can be photographed by a camera to obtain an image of the target vehicle, or the target vehicle can be recorded by a camera to obtain a video of the target vehicle, and then the image of the target vehicle is analyzed by an image recognition method, or the video of the target vehicle is analyzed by a video target detection method to determine whether the state of the target vehicle has changed.

[0062] S250: Determine whether the target vehicle changes from a stationary state to a driving state.

[0063] Specifically, when monitoring the state of the target vehicle in real time, it is determined in real time whether the state of the target vehicle changes to determine whether the target vehicle is converted from a stationary state to a driving state. If the target vehicle is converted from a stationary state to a driving state, S260 is executed to obtain the driving parameters of the target vehicle; if the target vehicle has not been converted from a stationary state to a driving state, S240 is executed to continue monitoring the state of the target vehicle.

[0064] S260: When it is detected that the target vehicle changes from a stationary state to a driving state, the driving parameters of the target vehicle are obtained.

[0065] The driving parameters include driving distance and / or driving speed.

[0066] Specifically, when it is monitored that the target vehicle changes from a stationary state to a driving state, the driving parameters of the target vehicle can be obtained. For example, the image or video of the target vehicle captured by the camera can be analyzed to obtain the driving distance of the target vehicle and / or the driving speed of the target vehicle.

[0067] S270: Determine whether the driving distance of the target vehicle is greater than a second preset distance, and / or whether the driving speed of the target vehicle is greater than a preset speed.

[0068] The second preset distance is a preset distance value used to determine whether the driving distance of the target vehicle meets the preset start condition of the current vehicle. The user can adjust and set the second preset distance according to actual use requirements, and the embodiment of the present application does not specifically limit this. For example, the second preset distance can be 1 meter.

[0069] The preset speed is a pre-set speed value used to determine whether the driving speed of the target vehicle meets the preset starting conditions of the current vehicle. The user can adjust and set the preset speed according to actual usage requirements, and the embodiments of the present application do not make specific limitations on this.

[0070] Specifically, after obtaining the driving distance and / or driving speed of the target vehicle, it can be determined whether the driving distance of the target vehicle is greater than a second preset distance, and / or whether the driving speed of the target vehicle is greater than the preset speed, so as to determine whether the driving parameters of the target vehicle meet the preset start-up conditions of the current vehicle. If the driving distance of the target vehicle is greater than the second preset distance, and / or the driving speed of the target vehicle is greater than the preset speed, it indicates that the driving parameters of the target vehicle meet the preset start-up conditions of the current vehicle, that is, the target vehicle is in a driving state and will not stop in a short time. At this time, S280 is executed to start the engine of the current vehicle; if the driving distance of the target vehicle is less than or equal to the second preset distance, and / or the driving speed of the target vehicle is less than or equal to the preset speed, it indicates that the driving parameters of the target vehicle do not meet the preset start-up conditions of the current vehicle, that is, the target vehicle is in a driving state but may stop again in a short time. At this time, S260 is executed to continue to monitor the target vehicle in real time to obtain the driving parameters of the target vehicle in real time.

[0071] S280: When the driving distance of the target vehicle is greater than a second preset distance, and / or the driving speed of the target vehicle is greater than a preset speed, starting the engine of the current vehicle through the start-stop system of the current vehicle.

[0072] The implementation process and technical principle of S280 are the same as those of S150, and reference may be made to the above description of S150, which will not be repeated here.

[0073] The technical solution provided by the present embodiment is that the current vehicle can control the engine of the current vehicle to stop according to the user's stop command; control the engine of the current vehicle to stop through the start-stop system of the current vehicle; when the engine of the current vehicle is in a stopped state, determine whether there is a target vehicle directly in front of the current vehicle; when there is a target vehicle directly in front of the current vehicle, monitor the state of the target vehicle; determine whether the target vehicle is converted from a stationary state to a driving state; when it is monitored that the target vehicle is converted from a stationary state to a driving state, obtain the driving parameters of the target vehicle; determine whether the driving distance of the target vehicle is greater than a second preset distance, and / or whether the driving speed of the target vehicle is greater than a preset speed; when the driving distance of the target vehicle is greater than the second preset distance, and / or the driving speed of the target vehicle is greater than the preset speed, start the engine of the current vehicle through the start-stop system of the current vehicle. In the above technical solution, the engine of the current vehicle is stopped according to the stop command of the user, or the engine of the current vehicle is stopped by the start-stop system of the current vehicle. At this time, the engine is in a stopped state, and the camera can be used to monitor the front of the current vehicle in real time to determine whether there is a target vehicle in front of the current vehicle, thereby further improving the accuracy of the engine start-stop control; when there is a target vehicle in front of the current vehicle, the camera is used to capture an image or video of the target vehicle, and the image or video is analyzed to determine the state of the target vehicle, and then determine whether the target vehicle is converted from a stationary state to a driving state, thereby achieving real-time determination of the state of the target vehicle according to the camera, thereby improving the accuracy of determining the state The calculation efficiency is changed and the implementation complexity is reduced; if the target vehicle is converted from a stationary state to a driving state, the driving distance and / or driving speed of the target vehicle are obtained, and when the driving distance of the target vehicle is greater than a second preset distance, and / or the driving speed of the target vehicle is greater than a preset speed, the engine of the current vehicle is started by the start-stop system of the current vehicle, and the engine start timing is determined by the driving distance and / or driving speed of the target vehicle, thereby further optimizing the engine start timing, thereby improving the accuracy of the engine start-stop control, and effectively avoiding the problem of being unable to determine the timing of starting the engine due to the absence of a signal light ahead or the signal light being blocked, and the problem of frequent engine start-stop in congested road conditions.

[0095] And / or when the driving speed of the target vehicle is greater than a preset speed, starting the engine of the current vehicle through the start-stop system of the current vehicle.

[0096] Those skilled in the art can clearly understand that for the convenience and simplicity of description, only the division of the above-mentioned functional modules is used as an example for illustration. In actual applications, the above-mentioned functions can be assigned to different functional modules as needed, that is, the internal structure of the device is divided into different functional modules to complete all or part of the functions described above.

If the driving parameters of the vehicle ahead meet the preset start conditions of the current vehicle, the engine of the current vehicle is started by the start-stop system of the current vehicle; if the driving parameters of the vehicle ahead do not meet the preset start conditions of the current vehicle, the vehicle ahead is continuously monitored in real time to obtain the driving parameters of the vehicle ahead in real time, and the start timing of the engine of the current vehicle is determined by the state and driving parameters of the vehicle ahead, so as to realize the start-stop control of the engine, optimize the start timing of the engine, improve the accuracy of the start-stop control of the engine, reduce fuel consumption and carbon dioxide emissions, and solve the problem of being unable to determine the start timing of the engine due to the absence of a signal light or the signal light being blocked ahead; when the driving parameters of the vehicle ahead meet the preset start conditions of the current vehicle, the engine is started by using the start-stop system, which effectively avoids frequent start-stop of the engine, solves the problem of frequent start-stop of the engine in congested road conditions, thereby improving the driving comfort of the user, reducing the wear of the engine, and extending the service life of the engine.
