Description

Technical Field

[0001] This application relates to the field of intelligent driving technology, and in particular to a control method, device, equipment and storage medium for vehicle cruise function. Background Technology

[0002] With the rapid development of automotive technology, most cars are now equipped with adaptive cruise control systems. Adaptive cruise control is an intelligent automatic control system. During vehicle operation, a distance sensor (radar) mounted at the front of the vehicle continuously scans the road ahead, while wheel speed sensors collect vehicle speed signals. When the distance to the vehicle in front becomes too small, the ACC control unit can coordinate with the anti-lock braking system and engine control system to apply appropriate braking to the wheels and reduce engine output power, thus maintaining a safe distance from the vehicle in front.

[0003] In related technologies, drivers need to perform one or even multiple button operations to activate the adaptive cruise control function. However, in a driving environment, drivers need to perform additional driving operations, which can easily lead to related accidents. Therefore, this method has low safety. Summary of the Invention

[0004] The main objective of this application is to provide a control method, device, equipment, and storage medium for vehicle cruise control, aiming to solve the technical problem of low safety in the prior art.

[0005] To achieve the above objectives, this application provides a control method for a vehicle cruise function, the control method for the vehicle cruise function comprising:

[0006] Real-time acquisition of vehicle driving condition information, including vehicle speed;

[0007] Determine whether the vehicle's speed exceeds a preset speed threshold;

[0008] If the vehicle's speed exceeds the speed threshold, a timer for a preset duration will be started.

[0009] Based on the timer and the vehicle speed, determine whether the vehicle meets the preset adaptive cruise conditions;

[0010] If the vehicle meets the conditions for adaptive cruise control, then the adaptive cruise control function is activated.

[0011] Optionally, the step of determining whether the vehicle meets the preset adaptive cruise conditions based on the timer and the vehicle speed includes:

[0012] If no driving condition information indicating that the brake pedal has been pressed is received within the specified time after the timer is started, and the vehicle speed continues to exceed the speed threshold, then it is determined that the vehicle speed meets the preset adaptive cruise control conditions.

[0013] Optionally, the step of determining whether the vehicle meets the preset adaptive cruise conditions based on the timer and the vehicle speed includes:

[0014] If, within the duration specified after the timer is started, driving condition information indicating that the brake pedal is depressed is received, or if the vehicle speed does not exceed the speed threshold, then it is determined that the vehicle speed does not meet the preset adaptive cruise control conditions.

[0015] Optionally, after the step of activating the adaptive cruise control function if the vehicle meets the adaptive cruise control conditions, the method includes:

[0016] When the adaptive cruise control function is enabled, if the driving condition information indicates that the brake pedal is depressed, the adaptive cruise control function will be disabled.

[0017] Optionally, after the step of activating the adaptive cruise control function if the vehicle meets the adaptive cruise control conditions, the method includes:

[0018] If the driving condition information does not meet the adaptive cruise conditions, then return to the step of determining whether the driving condition information meets the preset adaptive cruise conditions.

[0019] Optionally, the driving condition information further includes driving environment, road conditions, accelerator pedal status, and brake pedal status. Before the step of determining whether the vehicle speed exceeds a preset speed threshold, the method includes:

[0020] Determine whether the accelerator pedal and brake pedal states are faulty, whether the driving environment meets the brightness requirements for adaptive cruise control, and whether the road conditions are congested.

[0021] If the accelerator pedal state and brake pedal state are not faulty, the driving environment meets the brightness conditions for adaptive cruise control, and the road conditions do not reach the congestion conditions, then it is determined that the driving condition information meets the conditions for activating adaptive cruise control.

[0022] Once it is determined that the driving condition information meets the conditions for activating adaptive cruise control, the next step is to determine whether the vehicle speed exceeds a preset speed threshold.

[0023] Optionally, after the step of activating the adaptive cruise control function if the vehicle meets the adaptive cruise control conditions, the method includes:

[0024] When the adaptive cruise control function is activated, the system determines whether there is a target vehicle ahead of the vehicle based on the driving condition information.

[0025] If there is a target vehicle in front of the vehicle, the vehicle speed is adjusted to keep the distance between the vehicle and the target vehicle within a preset safe driving distance range until the driving condition information is received indicating that the brake pedal is pressed, and the adaptive cruise control function is turned off.

[0026] If there is no target vehicle ahead of the vehicle, the speed limit information of the current road segment is obtained, and the vehicle speed is adjusted based on the speed limit information until the driving condition information is received indicating that the brake pedal is pressed, and the adaptive cruise control function is turned off.

[0027] This application also provides a control device for a vehicle cruise control function, the control device for the vehicle cruise control function comprising:

[0032] The activation module is used to activate the adaptive cruise control function if the vehicle meets the adaptive cruise control conditions.

[0033] This application also provides a control device for a vehicle cruise control function, the control device comprising: a memory, a processor, and a program stored in the memory for implementing a control method for the vehicle cruise control function.

[0036] This application also provides a storage medium storing a program for a control method of implementing a vehicle cruise function, wherein the program for the control method of implementing a vehicle cruise function is executed by a processor to implement the steps of the control method of the vehicle cruise function.

[0037] This application provides a vehicle cruise control method, device, equipment, and storage medium. Compared to related technologies where drivers need to perform one or more button operations to activate adaptive cruise control, leading to lower safety, this application acquires vehicle driving condition information in real time, including vehicle speed; determines whether the vehicle speed exceeds a preset speed threshold; if the vehicle speed exceeds the speed threshold, activates a timer for a preset duration; based on the timer and the vehicle speed, determines whether the vehicle meets preset adaptive cruise control conditions; if the vehicle meets the adaptive cruise control conditions, activates the adaptive cruise control function. In other words, this application determines whether the vehicle has entered adaptive cruise control based on its driving speed, eliminating the need for manual button operation to activate adaptive cruise control and automatically controlling the vehicle to activate it, thereby improving vehicle safety.

[0046] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0047] like Figure 1 As shown, Figure 1 This is a schematic diagram of the terminal structure of the hardware operating environment involved in the embodiments of this application.

[0048] The terminal in this application embodiment can be a PC, or a smartphone, tablet computer, e-book reader, MP3 (Moving Picture Experts Group Audio Layer III) player, MP4 (Moving Picture Experts Group Audio Layer IV) player, portable computer, or other portable terminal devices with display functions.

[0054] Reference Figure 2 This application provides a method for controlling a vehicle cruise function, the method comprising:

[0055] Step S100: Obtain vehicle driving condition information in real time, wherein the driving condition information includes vehicle speed.

[0056] Step S200: Determine whether the vehicle's speed exceeds a preset speed threshold;

[0057] Step S300: If the vehicle speed exceeds the speed threshold, then start a timer for a preset duration.

[0058] Step S400: Based on the timer and the vehicle speed, determine whether the vehicle meets the preset adaptive cruise conditions;

[0059] Step S500: If the vehicle meets the adaptive cruise conditions, then the adaptive cruise function is activated.

[0060] In this embodiment, the application scenario is:

[0061] As an example, a scenario for controlling vehicle cruise control could be that a driver needs to activate adaptive cruise control while driving a vehicle equipped with it. To activate adaptive cruise control, the driver needs to perform one or more button presses to engage the function. Specifically, refer to... Figure 4 In traditional driving systems, drivers manually activate adaptive cruise control by pressing the adaptive cruise button. Once activated, adaptive cruise control automatically matches the vehicle's current speed, and the driver sets a distance to the next vehicle, thus enabling the adaptive cruise control function. However, additional driving maneuvers by the driver in a driving environment can easily lead to accidents, making this method less safe. To address this scenario, the vehicle cruise control method in this embodiment determines whether the vehicle has entered adaptive cruise control based on driving condition information during the vehicle's journey. It automatically activates adaptive cruise control without requiring manual button presses, thereby improving vehicle safety.

[0062] This embodiment aims to improve the safety and stability of vehicle driving.

[0063] In this embodiment, the control method for the vehicle cruise function is applied to the control device for the vehicle cruise function.

[0064] The specific steps are as follows:

[0065] Step S100: Obtain vehicle driving condition information in real time, wherein the driving condition information includes vehicle speed.

[0066] In this embodiment, the driving condition information includes, but is not limited to, vehicle status information, vehicle operating condition information, vehicle perception information, road alignment conditions, and road surface friction coefficient. The vehicle status information includes brake pedal status (including normal and fault states), accelerator pedal status (including normal and fault states), radar and camera status, etc. The vehicle operating condition information includes brake pedal commands (brake pedal commands are commands sent to the vehicle's central control system by the driver when pressing the brake pedal), accelerator pedal commands (accelerator pedal commands are commands sent to the vehicle's central control system by the driver when pressing the accelerator pedal), and vehicle speed (real-time speed information obtained using the vehicle's sensors), etc. The vehicle perception information includes, but is not limited to, the lateral distance between the adaptive cruise vehicle's center and the right edge of the outermost lane, the lateral distance between the adaptive cruise vehicle's center and the right edge of the outermost lane of the target vehicle (i.e., the vehicle in front), the relative distance between the adaptive cruise vehicle and the target vehicle, the relative speed between the adaptive cruise vehicle and the target vehicle, and the braking intention of the target vehicle. All of these vehicle perception information can be obtained using the vehicle's perception sensors.

[0067] Step S200: Determine whether the vehicle's speed exceeds a preset speed threshold;

[0068] In this embodiment, the device determines whether the current vehicle meets the conditions for entering the adaptive cruise control function based on the driving condition information. The adaptive cruise control conditions are preset conditions, which may be whether the vehicle speed meets certain conditions, whether the traffic congestion level supports the vehicle entering the adaptive cruise control function, or whether the ambient light level supports the vehicle entering the adaptive cruise control function.

[0069] In this embodiment, the driving condition information includes the vehicle speed. The device determines whether the current vehicle speed exceeds a preset speed threshold, wherein the speed threshold is a preset value, for example, the speed threshold is 20 km / h, and the current vehicle speed is 35 km / h, then it is determined that the current vehicle speed exceeds the preset speed threshold.

[0070] Step S300: If the vehicle speed exceeds the speed threshold, then start a timer for a preset duration.

[0071] In this embodiment, refer to Figure 5If the vehicle speed exceeds a preset speed threshold, the device starts a timer for a preset duration. The timer is used to calculate the time after the vehicle speed exceeds the preset speed threshold. The duration is a preset value. For example, when the device determines that the current vehicle speed exceeds the preset speed threshold, it starts a timer for 30 seconds.

[0072] Step S400: Based on the timer and the vehicle speed, determine whether the vehicle meets the preset adaptive cruise conditions;

[0073] In this embodiment, the device determines whether the vehicle meets the preset adaptive cruise conditions based on the timer and the vehicle speed. Specifically, within the time range of the timer, the vehicle speed meets the corresponding conditions, and the device determines whether the vehicle meets the preset adaptive cruise conditions accordingly.

[0074] Specifically, step S400 includes the following steps S410-S420:

[0075] Step S410: If no driving condition information of the brake pedal being pressed is received within the duration after the timer is started, and the vehicle speed continues to exceed the speed threshold, then it is determined that the vehicle speed meets the preset adaptive cruise control conditions.

[0076] In this embodiment, if the device does not receive driving condition information indicating that the brake pedal is pressed within the specified duration after the timer is started, it is determined that the vehicle speed meets the preset adaptive cruise control conditions. For example, if the speed threshold is 20 km / h, a 30-second timer is started when the vehicle speed exceeds 20 km / h. If the device does not receive driving condition information indicating that the brake pedal is pressed within the 30-second timer, it is determined that the vehicle speed meets the preset adaptive cruise control conditions.

[0077] Step S420: If, within the duration after the timer is started, driving condition information indicating that the brake pedal is depressed is received, or if the vehicle speed does not exceed the speed threshold, then it is determined that the vehicle speed does not meet the preset adaptive cruise control conditions.

[0078] In this embodiment, if the device receives driving condition information indicating that the brake pedal is depressed within the specified duration after the timer is started, it determines that the vehicle speed does not meet the adaptive cruise control conditions. For example, if the speed threshold is 20 km / h, and the timer is started for 30 seconds when the vehicle speed exceeds 20 km / h, if the device receives driving condition information indicating that the brake pedal is depressed within the 30-second timer period, it determines that the vehicle speed does not meet the preset adaptive cruise control conditions, and the device controls the vehicle to disengage from the adaptive cruise control function. Alternatively, if the device receives information indicating that the vehicle speed does not exceed the speed threshold, meaning the vehicle decelerates to below the speed threshold without the brake pedal being depressed, the device also determines that the vehicle speed does not meet the preset adaptive cruise control conditions.

[0079] Step S500: If the vehicle meets the adaptive cruise conditions, then the adaptive cruise function is activated.

[0080] In this embodiment, if the driving condition information meets the adaptive cruise conditions, the device activates the adaptive cruise function, that is, the vehicle enters the adaptive cruise mode (or function).

[0081] After step S300, where the vehicle meets the adaptive cruise control conditions, and the adaptive cruise control function is activated, the method includes the following step A100:

[0082] Step A100: When the adaptive cruise control function is enabled, if the driving condition information indicates that the brake pedal is depressed, then the adaptive cruise control function is disabled.

[0083] In this embodiment, when the adaptive cruise control function is enabled, if the device receives the driving condition information indicating that the brake pedal is depressed, the adaptive cruise control function will be deactivated. That is, the device continuously detects whether the brake pedal is depressed, and automatically exits the adaptive cruise control function when the brake pedal is depressed.

[0084] After step S500, where the vehicle meets the adaptive cruise control conditions, and the adaptive cruise control function is activated, the method includes the following step B100:

[0085] Step B100: If the driving condition information does not meet the adaptive cruise conditions, then return to the step of determining whether the driving condition information meets the preset adaptive cruise conditions.

[0086] In this embodiment, if the driving condition information does not meet the adaptive cruise conditions, the device returns to the step of determining whether the driving condition information meets the preset adaptive cruise conditions, that is, the process returns to the step of determining whether the vehicle automatically enters the adaptive cruise function. In other words, after the vehicle is started, the device determines in real time whether the vehicle meets the conditions for entering the adaptive cruise function, thereby automatically controlling the vehicle to activate the adaptive cruise function, which improves the safety of the vehicle.

[0087] After step S500, where the vehicle meets the adaptive cruise control conditions, and the adaptive cruise control function is activated, the method includes the following steps C100-C300:

[0088] Step C100: When the adaptive cruise control function is activated, determine whether there is a target vehicle in front of the vehicle based on the driving condition information;

[0089] In this embodiment, when the adaptive cruise control function is activated, the device determines whether there is a target vehicle in front of the vehicle based on the driving condition information. Specifically, the device acquires image information and location information of the vehicle in front of the vehicle based on preset radar and camera, thereby determining whether there is a target vehicle in front of the vehicle.

[0090] Step C200: If there is a target vehicle in front of the vehicle, adjust the vehicle speed to keep the distance between the vehicle and the target vehicle within a preset safe driving distance range until the driving condition information is received indicating that the brake pedal is pressed, and then turn off the adaptive cruise control function.

[0091] In this embodiment, if a target vehicle is located ahead of the vehicle, the device adjusts the vehicle speed to maintain a safe driving distance from the target vehicle within a preset safe driving range. This continues until the vehicle receives driving condition information indicating that the brake pedal is depressed, at which point the adaptive cruise control function is deactivated. Specifically, after the vehicle enters adaptive cruise control, the device continuously monitors the target vehicle ahead using radar and a camera, automatically adjusting the vehicle speed and distance based on the target vehicle to control the maximum safe driving distance. The vehicle controller continuously monitors whether the brake pedal is depressed; when the brake pedal is depressed, the adaptive cruise control function is automatically deactivated.

[0092] In step C300, if there is no target vehicle in front of the vehicle, the speed limit information of the current road segment is obtained, and the vehicle speed is adjusted based on the speed limit information until the driving condition information is received indicating that the brake pedal is pressed, and the adaptive cruise control function is turned off.

[0093] In this embodiment, if there is no target vehicle in front of the vehicle, the device obtains the speed limit information of the current road segment and adjusts the vehicle speed based on the speed limit information until the driving condition information is received indicating that the brake pedal is depressed, thus deactivating the adaptive cruise control function. Specifically, if there is no target vehicle in front of the vehicle, the device controls the vehicle to accelerate / decelerate, adjusts the maximum speed by comparing the maximum speed limit of the road segment with the map, and uses radar and cameras to continuously determine the surrounding driving environment and the distance to the nearest target vehicle in front, while continuously detecting whether the brake pedal is depressed. When the brake pedal is depressed, the adaptive cruise control function is automatically deactivated.

[0094] This application provides a vehicle cruise control method that, compared to related technologies where drivers need to perform one or more button operations to activate adaptive cruise control, leading to lower safety, acquires real-time vehicle driving condition information, including vehicle speed; determines whether the vehicle speed exceeds a preset speed threshold; and activates adaptive cruise control if the vehicle meets the adaptive cruise conditions. In other words, this application determines whether the vehicle should engage adaptive cruise control based on driving condition information during operation, eliminating the need for manual button operation and automatically controlling the vehicle to activate adaptive cruise control, thereby improving vehicle safety.

[0095] Based on the first embodiment described above, this application also provides another embodiment, wherein the control method for the vehicle cruise function includes the following steps:

[0096] Specifically, before step S200, which determines whether the vehicle speed exceeds a preset speed threshold, the method includes the following steps D100-D200:

[0097] Step D100: Determine whether the accelerator pedal status and brake pedal status are faulty, whether the driving environment meets the brightness conditions for adaptive cruise control, and whether the road conditions meet the congestion conditions.

[0098] In this embodiment, the driving condition information also includes driving environment, road conditions, accelerator pedal status, and brake pedal status. The device determines in real time whether the accelerator pedal status and brake pedal status are faulty, whether the driving environment meets the brightness conditions for adaptive cruise control, and whether the road conditions are congested.

[0099] Step D200: If the accelerator pedal state and brake pedal state are not faulty, the driving environment meets the brightness conditions for adaptive cruise control, and the road conditions do not reach the congestion conditions, then it is determined that the driving condition information meets the preset adaptive cruise control conditions.

[0100] In this embodiment, if the accelerator pedal and brake pedal states are not faulty, the driving environment meets the brightness requirements for adaptive cruise control, and the road conditions are not congested, then the device determines that the driving condition information meets the preset adaptive cruise control conditions. It should be noted that if the vehicle does not meet any of the above conditions, then the driving condition information does not meet the preset adaptive cruise control conditions. That is, if the accelerator pedal state is faulty, or the brake pedal state is faulty, or the driving environment does not meet the brightness requirements for adaptive cruise control, or the road conditions are congested, then the driving condition information does not meet the preset adaptive cruise control conditions.

[0101] In this embodiment, the central control map system monitors the driving environment and road conditions through radar and cameras, and determines whether the road conditions are congested, the weather, and whether the brightness of the driving environment supports the vehicle to enter the adaptive cruise control function, thereby further improving the vehicle's operating safety and stability.

[0102] Based on the first and second embodiments described above, this application also provides another embodiment, referred to... Figure 6 The control method for the vehicle cruise function includes the following steps E100-E400:

[0103] Step E100: When the vehicle is running normally, the device detects whether there is a malfunction in the vehicle. If there is no malfunction, when the vehicle speed is greater than 20 km / h, the device starts a 30-second timer. If the device detects that the brake pedal is pressed, the timer is exited and the timer restarts when the vehicle speed is greater than 20 km / h again.

[0104] Step E200: After the 30-second timer stops, the device checks whether the brake pedal and accelerator pedal are normal. If a fault is found, the device saves the corresponding fault, exits the adaptive cruise control function, and alerts the driver to the fault through the instrument panel.

[0105] Step E300: When the brake pedal and accelerator pedal are found to be fault-free, the device monitors the driving environment and road conditions through radar, camera and central control map system to determine whether the road conditions are congested and whether the brightness of the surrounding driving environment supports the vehicle to enter the adaptive cruise function. If the entry conditions are not met, the adaptive cruise function is exited directly and the driver is prompted through the instrument panel.

[0106] In step E400, when the entry conditions are met, the device controls the vehicle to enter adaptive cruise control mode and notifies the driver via the instrument panel that adaptive cruise control has been entered. Once in adaptive cruise control mode, the device continuously monitors the target vehicle ahead using radar and a camera, automatically adjusting the vehicle speed and distance based on the target vehicle to maintain the maximum safe driving distance. Simultaneously, the device continuously monitors whether the brake pedal is depressed. When the brake pedal is depressed, the device automatically exits adaptive cruise control mode and notifies the driver via the instrument panel. The process returns to the timing phase to prepare for the next entry of adaptive cruise control.

[0107] In step E400, when there is no target vehicle ahead, the device controls the vehicle to accelerate / decelerate, adjusting the maximum speed according to the speed limit of the target road segment on the central control map. The device uses radar and cameras to continuously assess the surrounding driving environment and the distance to the nearest target vehicle ahead, while continuously monitoring whether the brake pedal is depressed. When the brake pedal is depressed, the adaptive cruise control function is automatically disengaged, and the driver is notified via the instrument panel. The process returns to the timing phase to prepare for the next engagement of adaptive cruise control.

[0108] In this embodiment, the device monitors the driving environment and road conditions through radar, cameras, and a central control map system to determine whether the road is congested and whether the weather and ambient light support the vehicle's adaptive cruise control function. This improves vehicle safety and stability. By collecting data on the accelerator pedal, brake pedal, and vehicle speed, the device can analyze the vehicle's operating status and better determine whether adaptive cruise control can be activated. Combined with the map, it can effectively determine road conditions, traffic lights, and other situations, resulting in better adaptability.
