[0021] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
[0022] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure as detailed in the appended claims.
[0023] Figure 1 A flowchart of a method for restoring steering wheel auxiliary control provided in an embodiment of the present disclosure.
[0024] like Figure 1 As shown, the steering wheel auxiliary control recovery method includes the following steps:
[0025] S101, identifying that the steering wheel auxiliary control is in an inhibited state, and then monitoring the state of the vehicle.
[0026] It should be noted that the vehicle's assisted driving function can be divided into two dimensions, namely the longitudinal dimension and the lateral dimension. The longitudinal dimension is to automatically control the vehicle's speed to achieve control of the vehicle's speed, and the lateral dimension is to automatically control the vehicle's steering wheel rotation to stabilize the vehicle's driving direction.
[0027] It should be noted that in the lateral dimension, in order to keep the vehicle centered in the lane, it relies on capturing the lane lines to control the turning of the steering wheel. When the lane lines cannot be captured, the vehicle's lateral control is lost, that is, the steering wheel auxiliary control is in an inhibited state.
[0028] For example, in various scenarios such as temporary lane selection, temporary detour around obstacles, and temporary route selection, the lane lines may not be captured, that is, lateral control is lost and steering wheel auxiliary control is inhibited.
[0029] It should be noted that the present disclosure does not limit the specific method for identifying that the steering wheel auxiliary control is in the inhibited state, and it can be selected according to actual circumstances.
[0030] Optionally, the lane line of the road on which the vehicle is traveling may be detected, and if no lane line is identified within a first set time period, it is determined that the steering wheel assist control of the vehicle is in an inhibited state.
[0031] S102: Determine whether the current state of the vehicle satisfies a determination condition for resuming steering wheel auxiliary control.
[0032] It should be noted that in the related art, when the vehicle's lateral control is lost, that is, the steering wheel assist control is in an inhibited state, the steering wheel assist control is quickly restored after the lane line is recaptured, causing the vehicle to frequently switch from the steering wheel assist control being in an inhibited state to the steering wheel assist control being restored, resulting in a poor user experience.
[0033] The present disclosure proposes a method for restoring steering wheel assisted control. When it is identified that the steering wheel assisted control is in an inhibited state, the state of the vehicle is monitored. When the current state of the vehicle meets the judgment conditions for restoring the steering wheel assisted control, the steering wheel assisted control of the vehicle is restored, thereby reducing the frequency of restoring the steering wheel assisted control of the vehicle and avoiding the phenomenon of frequently restoring the steering wheel assisted control of the vehicle from a suppressed state.
[0034] It should be noted that the present disclosure does not limit the specific method for determining whether the current state of the vehicle meets the determination conditions for resuming steering wheel auxiliary control, and the method can be selected according to actual conditions.
[0035] Optionally, the detection signal of the steering wheel torque sensor can be obtained, the lane lines on both sides of the road where the vehicle is located are continuously identified, the lateral distance between the lane center line of the road where the vehicle is located and the vehicle center line is obtained, and the angle between the lane line of the road where the vehicle is located and the vehicle center line is obtained. Based on the detection signal, the identification results of the lane lines on both sides, the lateral distance and the angle, it is determined whether the current state meets the judgment conditions for restoring steering wheel auxiliary control.
[0036] S103: If the current state satisfies the determination condition, the steering wheel auxiliary control of the vehicle is restored.
[0037] In an embodiment of the present disclosure, in response to the detection signal, the recognition results of the lane lines on both sides, the lateral distance and the angle all satisfying their respective corresponding judgment conditions for resuming the steering wheel assist control, it is determined that the current state satisfies the judgment conditions for resuming the steering wheel assist control.
[0038] Optionally, if it is determined that the current state meets the judgment conditions for resuming steering wheel assisted control, that is, it is determined that the detection signal meets the first judgment condition for resuming steering wheel assisted control, it is determined that the recognition result of the lane lines on both sides meets the second judgment condition for resuming steering wheel assisted control, it is determined that the lateral distance meets the third judgment condition for resuming steering wheel assisted control, and it is determined that the angle meets the fourth judgment condition for resuming steering wheel assisted control, then the steering wheel assisted control of the vehicle is restored.
[0039] In the embodiment of the present disclosure, if the current state does not meet the determination conditions, the steering wheel assist control of the vehicle is maintained in an inhibited state, that is, if the first determination condition, the second determination condition, the third determination condition and the fourth determination condition for restoring the steering wheel assist control are not met at the same time, the steering wheel assist control of the vehicle is maintained in an inhibited state.
[0040] According to a method for restoring steering wheel assisted control of an embodiment of the present disclosure, by identifying that the steering wheel assisted control is in an inhibited state, the state of the vehicle is monitored, and it is determined whether the current state of the vehicle meets the determination conditions for restoring the steering wheel assisted control. If the current state meets the determination conditions, the steering wheel assisted control of the vehicle is restored. Therefore, the present disclosure restores the steering wheel assisted control of the vehicle when it identifies that the steering wheel assisted control is in an inhibited state and the current state of the vehicle meets the determination conditions for restoring the steering wheel assisted control, thereby avoiding the phenomenon of frequently restoring the steering wheel assisted control of the vehicle from being in an inhibited state, reducing the frequency of restoring the steering wheel assisted control of the vehicle from being in an inhibited state, improving the safety and reliability of autonomous driving, and improving the user experience.
[0041] Figure 2 This is a flowchart of a method for restoring steering wheel auxiliary control according to an embodiment of the present disclosure. Based on the above embodiment, further combined with Figure 2 The specific process of determining whether the current state of the vehicle satisfies the conditions for resuming the steering wheel auxiliary control is explained, including the following steps:
[0042] S201, obtaining a detection signal from a steering wheel torque sensor.
[0043] Optionally, signal detection may be performed based on a steering wheel torque sensor of the vehicle to obtain a detection signal of the steering wheel torque sensor, wherein the detection signal at least includes a torque value A of the steering wheel.
[0044] S202: Continuously identify lane markings on both sides of the road where the vehicle is located.
[0045] It should be noted that the present disclosure does not limit the specific method of continuously identifying the lane lines on both sides of the road where the vehicle is located, and can be selected according to actual conditions.
[0046] Optionally, the vehicle can be positioned using a high-precision map and high-precision positioning system pre-installed in the vehicle to continuously identify the lane lines on both sides of the road where the vehicle is located.
[0047] Optionally, during the driving process of the vehicle, if the high-precision positioning signal is unavailable, the lane lines on both sides of the road where the vehicle is located can be continuously identified through the on-board camera.
[0048] S203: Obtain a lateral distance between a lane centerline of the road where the vehicle is located and a centerline of the vehicle.
[0049] It should be noted that the present disclosure does not limit the specific method of obtaining the lateral distance between the lane centerline of the road where the vehicle is located and the vehicle centerline, and can be selected according to actual circumstances.
[0050] Optionally, the vehicle can be positioned using a high-precision map and a high-precision positioning system pre-installed in the vehicle to obtain the lateral distance between the lane centerline of the road on which the vehicle is located and the vehicle centerline.
[0051] For example, the vehicle can be positioned using a high-precision map and high-precision positioning system pre-installed in the vehicle to obtain first position information of the vehicle's centerline and second position information of the vehicle's centerline. Based on the first position information and the second position information, the lateral distance between the lane centerline of the road where the vehicle is located and the vehicle's centerline can be obtained.
[0052] Optionally, the lateral distance D between the center line of the lane of the road where the vehicle is located and the center line of the vehicle can be obtained by using an on-board camera.
[0053] For example, if Figure 3As shown, a road image can be captured by a vehicle-mounted camera, and the position information of the lane centerline can be obtained based on the captured road image. Based on the position information of the lane centerline and the position information of the vehicle centerline, the lateral distance D between the lane centerline of the road where the vehicle is located and the vehicle centerline can be obtained.
[0054] S204: Obtain the angle between the lane line of the road where the vehicle is located and the center line of the vehicle.
[0055] It should be noted that the present disclosure does not limit the specific method of obtaining the angle between the lane line of the road where the vehicle is located and the center line of the vehicle, and can be selected according to actual conditions.
[0056] Optionally, the angle α between the lane line of the road where the vehicle is located and the center line of the vehicle can be obtained through a vehicle-mounted camera.
[0057] For example, if Figure 4 As shown, a road image can be captured by a vehicle-mounted camera, and the position information of the lane line can be obtained based on the captured road image. Based on the position information of the lane line and the position information of the vehicle center line, the angle α between the lane line of the road where the vehicle is located and the vehicle center line can be obtained.
[0058] S205 , judging whether the current state satisfies the determination conditions for resuming the steering wheel auxiliary control based on the detection signal, the recognition results of the lane lines on both sides, the lateral distance, and the angle.
[0059] In the embodiment of the present disclosure, after obtaining the detection signal, the recognition results of the lane lines on both sides, the lateral distance and the angle, it is possible to judge whether the current state meets the judgment conditions for restoring the steering wheel auxiliary control based on the detection signal, the recognition results of the lane lines on both sides, the lateral distance and the angle.
[0060] Optionally, in response to the detection signal, the recognition results of the lane lines on both sides, the lateral distance and the angle all satisfying their respective corresponding judgment conditions for resuming the steering wheel auxiliary control, it is determined that the current state satisfies the judgment conditions for resuming the steering wheel auxiliary control.
[0061] The following explains the specific process of determining whether the current state meets the judgment conditions for resuming steering wheel auxiliary control when the detection signal, the recognition results of the lane lines on both sides, the lateral distance and the angle all meet their corresponding judgment conditions for resuming steering wheel auxiliary control.
[0062] With respect to the detection signal, it can be determined based on the detection signal whether the steering wheel of the vehicle has switched from the state of being actively steered by the user to the state of being released by the user, and it can be determined that the detection signal meets the first determination condition for resuming steering wheel auxiliary control.
[0063] Optionally, if the detection signal is greater than a first set torque threshold, the first duration during which the detection signal is greater than the first set torque threshold is determined; if the first duration is greater than a second set duration, it is determined that the steering wheel is in a state of being actively steered by the user; the detection signal is continuously detected while the steering wheel is in a state of being actively steered by the user; if the detection signal is less than the second set torque threshold, the second duration during which the detection signal is less than the second set torque threshold is determined; if the second duration is greater than a third set duration, it is determined that the steering wheel has entered a state of being released by the user.
[0064] It should be noted that the present disclosure does not limit the settings of the first set threshold and the second set time length, and they can be set according to actual conditions.
[0065] Optionally, in order to more accurately determine whether the steering wheel is in a state of being actively steered by the user, different first set torque thresholds and second set time lengths corresponding to different first set torque thresholds can be determined to determine whether the steering wheel is in a state of being actively steered by the user.
[0066] For example, the first threshold value may be preset as A th1 , The second setting duration is T p1 ; The first threshold value can be preset to A th2 , The second setting duration is T p2 ; The first threshold value can be preset to A th3 , The second setting duration is T p3 .
[0067] In an embodiment of the present disclosure, if the detection signal is greater than a first set torque threshold, the first duration of the detection signal being greater than the first set torque threshold is determined; if the first duration is greater than the second set duration, it is determined that the steering wheel is in a state of being actively turned by the user.
[0068] For example: for the torque value in the detection signal A, the first set threshold is A th1 , The second setting duration is T p1 , if A>A th1 , and A>A th1 The first duration of is T1, if T1>T p1 , it is determined that the steering wheel is in the state of being actively steered by the user; for example: for the torque value in the detection signal is A, the first set threshold is A th2 , The second setting duration is T p2 , if A>A th2 , and A>A th2 The first duration of is T1, if T1>T p2 , it is determined that the steering wheel is in the state of being actively steered by the user; for another example: for the torque value in the detection signal is A, the first set threshold is A th3, The second setting duration is T p3 , if A>A th3 , and A>A th3 The first duration of is T1, if T1>T p3 , it is determined that the steering wheel is in a state of being actively turned by the user.
[0069] In an embodiment of the present disclosure, after determining that the steering wheel is in a state of being actively steered by the user, the detection signal is continuously detected while the steering wheel is in a state of being actively steered by the user. If the detection signal is less than a second set torque threshold, the second duration during which the detection signal is less than the second set torque threshold is determined. If the second duration is greater than a third set duration, it is determined that the steering wheel has entered a state of being released by the user.
[0070] For example, when the steering wheel is actively turned by the user, the detection signal is continuously detected. For the torque value in the current detection signal, the second set threshold is A. th4 , The third setting duration is T p4 , if B>A th4 , and B>A th4 The second duration of T is T2, if T2>T p4 , it is determined that the steering wheel has entered the state of being released by the user.
[0071] It should be noted that the present disclosure does not limit the setting of the third set time length and the second set threshold value, and can be set according to actual conditions. Optionally, the third set time length T can be set p4 5 seconds.
[0072] In an embodiment of the present disclosure, if it is determined that the steering wheel of the vehicle is switched from a state of being actively steered by the user to a state of being released by the user, it is determined that the detection signal meets the first determination condition for resuming steering wheel auxiliary control.
[0073] Regarding the recognition result of the lane markings on both sides, in response to the lane markings on both sides entering the unrecognized state from the recognized state, and then entering the re-recognized state from the unrecognized state, it is determined that the recognition result of the lane markings on both sides meets the second judgment condition for resuming steering wheel assist control.
[0074] It should be noted that by continuously identifying the lane lines on both sides of the road where the vehicle is located, the recognition results of the lane lines on both sides can be determined. The specific process can be found in the above embodiment and will not be repeated here. When the lane lines on both sides go from the recognized state to the unrecognized state, and from the unrecognized state to the re-recognized state, it is determined that the recognition results of the lane lines on both sides meet the second judgment condition for resuming steering wheel auxiliary control.
[0075] Optionally, a third duration of the state in which the two-sided lane markings are re-recognized is obtained. If the third duration is greater than or equal to a fourth set duration, it is determined that the current state meets the second determination condition of the steering wheel auxiliary control.
[0076] It should be noted that the present disclosure does not limit the setting of the fourth set time length, and it can be set according to actual conditions. p5 5 seconds.
[0077] For example, if the third duration of the double-sided lane line entering the state of being recognized again is T3, if T3 ≥ T p5 , it is determined that the current state meets the second determination condition of the steering wheel auxiliary control.
[0078] Regarding the lateral distance, if the lateral distance is less than the set distance threshold, it is determined that the lateral distance meets the third determination condition for resuming the steering wheel assist control.
[0079] It should be noted that the present disclosure has no effect on the distance threshold D th There is no limitation on the setting, and it can be set according to the actual situation.
[0080] For example, for a horizontal distance of D, the distance threshold is D th , if D>D th , it is determined that the lateral distance meets the third determination condition for resuming the steering wheel auxiliary control.
[0081] Regarding the included angle, if the included angle is less than the set angle threshold, it is determined that the included angle meets the fourth determination condition for resuming the steering wheel auxiliary control.
[0082] It should be noted that the present disclosure has no effect on the angle threshold α. th There is no limitation on the setting, and it can be set according to the actual situation.
[0083] For example, for an angle of α, the angle threshold is α th , if α>α th , it is determined that the included angle meets the fourth determination condition for resuming steering wheel auxiliary control.
[0084] In the embodiment of the present disclosure, if it is determined that the current state meets the judgment conditions for resuming the steering wheel assisted control, that is, it is determined that the detection signal meets the first judgment condition for resuming the steering wheel assisted control, it is determined that the recognition result of the lane lines on both sides meets the second judgment condition for resuming the steering wheel assisted control, it is determined that the lateral distance meets the third judgment condition for resuming the steering wheel assisted control, and it is determined that the angle meets the fourth judgment condition for resuming the steering wheel assisted control, then the steering wheel assisted control of the vehicle is restored.
[0085] In the embodiment of the present disclosure, if the current state does not meet the determination conditions, that is, the first, second, third and fourth determination conditions for resuming the steering wheel assist control are not met at the same time, the vehicle's steering wheel assist control is maintained in an inhibited state.
[0086] According to a method for restoring steering wheel assisted control of an embodiment of the present invention, by obtaining the detection signal of the steering wheel torque sensor, the lane lines on both sides of the road where the vehicle is located are continuously identified, the lateral distance between the lane center line of the road where the vehicle is located and the vehicle center line is obtained, and the angle between the lane line of the road where the vehicle is located and the vehicle center line is obtained. According to the detection signal, the recognition result of the lane lines on both sides, the lateral distance and the angle, it is judged whether the current state meets the judgment condition for restoring the steering wheel assisted control. When the detection signal, the recognition result of the lane lines on both sides, the lateral distance and the angle all meet their respective corresponding judgment conditions for restoring the steering wheel assisted control, it is determined that the current state meets the judgment condition for restoring the steering wheel assisted control, and the steering wheel assisted control of the vehicle is restored, avoiding the phenomenon of frequently restoring the steering wheel assisted control of the vehicle from being in an inhibited state, reducing the frequency of restoring the steering wheel assisted control of the vehicle from being in an inhibited state, improving the safety and reliability of autonomous driving, and improving the user experience.
[0087] The specific process of the steering wheel auxiliary control recovery method proposed in the present disclosure is explained below.
[0088] For example, if Figure 5As shown, during vehicle driving, by detecting the lane lines of the road on which the vehicle is traveling, if no lane lines are recognized within a first set time period, it is determined that the vehicle's steering wheel auxiliary control is in an inhibited state, that is, the vehicle's lateral control is lost, and the vehicle's state is monitored, that is, a detection signal of a steering wheel torque sensor is obtained. If the detection signal is greater than a first set torque threshold, a first duration during which the detection signal is greater than the first set torque threshold is determined. If the first duration is greater than a second set time period, it is determined that the steering wheel is in a state of being actively steered by the user. While the steering wheel is in the state of being actively steered by the user, the detection signal is continuously detected. If the detection signal is less than a second set torque threshold, a second duration during which the detection signal is less than the second set torque threshold is determined. If the second duration is greater than a third set time period, it is determined that the steering wheel has entered a state of being released by the user. It is determined that the detection signal meets the first determination condition for resuming the steering wheel auxiliary control, and the lane lines on both sides of the road on which the vehicle is located are continuously recognized. In response to the lane lines on both sides transitioning from the recognized state to the unrecognized state, The vehicle is identified as being in a recognized state and enters a recognized state again from an unrecognized state, and the duration of the two-sided lane markings entering the recognized state again is obtained. If the duration is greater than or equal to a fourth set duration, it is determined that the current state meets the second determination condition of the steering wheel assist control, and the lateral distance between the lane centerline of the road where the vehicle is located and the vehicle centerline is obtained. If the lateral distance is less than the set distance threshold, it is determined that the lateral distance meets the third determination condition for resuming the steering wheel assist control, and the angle between the lane line of the road where the vehicle is located and the vehicle centerline is obtained. If the angle is less than the set angle threshold, it is determined that the angle meets the fourth determination condition for resuming the steering wheel assist control. When the first determination condition, the second determination condition, the third determination condition and the fourth determination condition for resuming the steering wheel assist control are met at the same time, the steering wheel assist control of the vehicle is restored. If the first determination condition, the second determination condition, the third determination condition and the fourth determination condition for resuming the steering wheel assist control are not met at the same time, the steering wheel assist control of the vehicle is maintained in the inhibited state.
[0089] To sum up, the steering wheel assisted control recovery method proposed in the present invention monitors the state of the vehicle by identifying that the steering wheel assisted control is in an inhibited state, and determines that the detection signal meets the first judgment condition for recovering the steering wheel assisted control, determines that the recognition result of the lane lines on both sides meets the second judgment condition for recovering the steering wheel assisted control, determines that the lateral distance meets the third judgment condition for recovering the steering wheel assisted control, and determines that the angle meets the fourth judgment condition for recovering the steering wheel assisted control, then recovers the steering wheel assisted control of the vehicle, avoids the phenomenon of frequently recovering the steering wheel assisted control of the vehicle from being in an inhibited state, reduces the frequency of recovering the steering wheel assisted control of the vehicle from being in an inhibited state, improves the safety, reliability and stability of autonomous driving, and improves the user experience.

[0098] Furthermore, the judgment module 120 is also used to: if the detection signal is greater than a first set torque threshold, determine a first duration during which the detection signal is greater than the first set torque threshold; if the first duration is greater than a second set duration, determine that the steering wheel is in a state of being actively steered by the user; continue to detect the detection signal while the steering wheel is in a state of being actively steered by the user; if the detection signal is less than the second set torque threshold, determine a second duration during which the detection signal is less than the second set torque threshold; if the second duration is greater than a third set duration, determine that the steering wheel has entered a state of being released by the user.
[0099] Furthermore, the judgment module 120 is also used to: in response to the two-sided lane markings entering an unrecognized state from an identified state, and then entering a re-recognized state from the unrecognized state, determine that the recognition result of the two-sided lane markings meets the second judgment condition for resuming steering wheel auxiliary control.
[0100] Furthermore, the device 1000 is also used to: obtain the third duration of the two-sided lane marking entering the state of being recognized again; if the third duration is greater than or equal to the fourth set duration, determine that the current state meets the second judgment condition of steering wheel auxiliary control.
[0101] Furthermore, the judgment module 120 is further configured to: if the lateral distance is less than a set distance threshold, determine that the lateral distance satisfies a third judgment condition for resuming steering wheel auxiliary control.
[0102] Furthermore, the judgment module 120 is further configured to: if the included angle is less than a set angle threshold, determine that the included angle satisfies a fourth judgment condition for resuming steering wheel auxiliary control.
[0103] Furthermore, the device 1000 is further configured to: if the current state does not satisfy the determination condition, maintain the steering wheel auxiliary control of the vehicle in an inhibited state.
[0104] Furthermore, the recognition module 110 is further configured to detect lane lines of the road on which the vehicle is traveling, and if no lane lines are recognized within a first set time period, determine that the steering wheel auxiliary control of the vehicle is in an inhibited state.
[0105] According to a steering wheel assist control recovery device of an embodiment of the present disclosure, by identifying that the steering wheel assist control is in an inhibited state, the vehicle state is monitored, and it is determined whether the current state of the vehicle satisfies the determination conditions for restoring the steering wheel assist control. If the current state satisfies the determination conditions, the vehicle's steering wheel assist control is restored. Thus, the present disclosure restores the vehicle's steering wheel assist control upon identifying that the steering wheel assist control is in an inhibited state and the vehicle's current state satisfies the determination conditions for restoring the steering wheel assist control, thereby avoiding the phenomenon of frequently restoring the vehicle's steering wheel assist control from being in an inhibited state, reducing the frequency of restoring the vehicle's steering wheel assist control from being in an inhibited state, improving the safety and reliability of autonomous driving, and enhancing the user experience.
