Abstract
Description
Technical Field
[0001] The present invention relates to the field of safe intelligent driving technology, and in particular to a voice-based turn prompt method, system, medium, electronic equipment and vehicle. Background Art
[0002] The statements in this section merely provide background art related to the present invention and do not necessarily constitute prior art.
[0003] With the advancement of sensor technology, information processing technology, measurement technology, and computer technology, intelligent driving systems (both assisted and unmanned) have also experienced rapid growth. Consumers are increasingly focused on driving safety and comfort, which requires sensors that can identify vehicles ahead in the same lane and alert the driver when obstacles are present or automatically change the vehicle's state to avoid accidents. Major international automotive companies are also committed to research in this area and have developed a series of safety driving systems, such as collision warning (CW), lane deviation warning (LDW), and intelligent cruise control (ICC). For example, intelligent driving systems for automobiles use binocular stereo machine vision as the primary means of road environment perception. Machine vision-based intelligent driving, also known as autonomous driving, is viewed within the automotive industry as a gradual process, ultimately culminating in autonomous driving. Currently, what major automakers call autonomous driving is more about integrating various intelligent assistance systems to enable vehicles to perform specific "autonomous" maneuvers, such as lane changing and overtaking, making them more intelligent.
[0004] At present, there are more and more safety accidents caused by accidental factors, especially for novice drivers. Since they have just started driving and are not proficient in driving skills, they will inevitably become nervous and uneasy, which will greatly increase the accident rate. At the same time, the current road conditions are becoming more and more complicated, and car drivers are distracted. It is sometimes more difficult for novices to distinguish turning problems at traffic lights. As a result, due to the novice's wrong turns, the frequency of traffic violations or traffic accidents by drivers increases, and the driver's safety index is reduced.
[0005] Therefore, making driving safer has always been a top priority for automakers. With the rapid development of technology, various safety driving systems have been introduced to ensure safe driving, such as anti-lock braking systems (ABS), electronic stability control (ESP), automatic traction control (ASR), electronic brake force distribution (EBD), electronic brake assist (EBA), lane departure warning (LDW), lane change assist (LCA), and advanced driver assistance systems (ADAS). These systems are all developed to enhance user safety.
[0006] The inventors found that lanes are becoming more and more complicated, and some novice drivers have a vague memory of traffic rules, which often causes them to make some wrong operations at intersections. The current navigation map can play a certain driving reminder function, but it often requires opening the navigation map to be realized, and most of the current navigation maps can only provide vague reminders, such as "Please use the left lane", "Please use the right lane", etc., and often cannot provide more intelligent turning reminders for novices. Summary of the Invention

It can help drivers make turning judgments and provide voice prompts, avoiding traffic violations or traffic accidents that may occur as a result.

[0041] Figure 1 This is a flow chart of the voice-based turn prompt method provided in Example 1 of the present invention. DETAILED DESCRIPTION
[0042] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0043] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.
[0044] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0045] In the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.
[0046] Example 1:
[0047] like Figure 1 As shown, embodiment 1 of the present invention provides a voice-based turn prompt method, including the following process:
[0048] S1: Use a third-party map SDK (Software Development Kit) or ADAS-TLR (ADAS stands for Advanced Driving Assistance System; TLR stands for Traffic Light Recognition) or a camera (image recognition) to identify road conditions and turn signals, such as the vehicle's current lane and the corresponding turn signal markings.
[0049] Use image recognition or third-party navigation map information to obtain the traffic light's turn sign and countdown information; measure the distance between the current vehicle and the red light intersection (this can be achieved by using a third-party map SDK or ADAS-TLR, or by using on-board sensors) so that corresponding photo taking and image recognition functions can be performed based on the distance.
[0050] S2: Determine whether the current vehicle distance to the intersection is less than or equal to 20m (i.e., the first distance threshold)
[0051] This is used to determine whether the current vehicle is less than or equal to 20 meters away from the red light (it can be understood that those skilled in the art can set the first distance threshold according to the specific circumstances of the system design, such as 19 meters, 25 meters, etc., which will not be repeated here). If it is less than or equal to 20 meters, continue to execute the subsequent steps, otherwise return to the previous step.
[0052] S3: Current lane identification
[0053] Use a third-party map (or use on-board sensors or cameras for identification) to identify which lane the vehicle is currently in. This information can be obtained using the corresponding SDK of the third-party map navigation.
[0054] S4: Current turning direction w
[0055] Determine which direction the vehicle can turn when it is in the current road lane. This information can be combined with the lane information and the turn marks on the lane to determine the direction in which the current lane can turn.
[0056] S5: Vehicle turn signal w2
[0057] Records the turn signal actively operated by the user. This signal indicates the user's subjective turning intention and is used as a turning prompt.
[0058] S6: Signal Identification
[0059] This embodiment mainly identifies the turn mark and countdown information of the traffic light, and determines which direction the red light allows to turn based on the turn comparison of the traffic light;
[0060] The countdown information on the traffic light sign is used to provide data support for the subsequent logical information; this embodiment can use the ADAS-TLR system or image recognition technology to identify traffic light signal information.
[0061] S7: Traffic light can turn direction w1
[0062] The signal recognition system identifies the traffic light signs and then uses calculations to determine which direction to turn.
[0063] S8: Countdown
[0064] The countdown information of the red light change is identified by the signal recognition system, which can be identified using image recognition technology or obtained using third-party navigation software.
[0065] S9: (w1&w)&&(t>8)
[0066] This judgment is the entry logic of the turn prompt and is also the most important judgment. It is used to determine whether the lane w1 where the current vehicle is located intersects with the turnable lane recognized by the red traffic light mark, that is, whether w1&w is true;
[0067] If it is true and the traffic light countdown is greater than 8s (i.e. the first time threshold, 8s is to ensure that there is enough time to go through the traffic light. This value can also be calculated based on the current vehicle speed in the actual system, or selected and set by technicians in this field according to specific working conditions, for example, 7s, 9s, etc., which will not be repeated here), the vehicle lane meets the conditions for turning direction, and the vehicle can turn.
[0068] S10: w2&w1&w
[0069] If the vehicle's current lane's turning direction w1 (byte array type, because there may be more than one turning direction) matches the turn direction w satisfied by the red light and the vehicle's turn signal w2, and if w2&w1&w are true, then the red light, the lane, and the user's steering intention are consistent, then a voice prompt "Master, master, turn!" (i.e., the first voice prompt) will be used; otherwise, a voice prompt "You can turn left" or "You can turn right" (i.e., the second voice prompt) will be used, where the direction of turn is determined by which of w1&w is true.
[0070] It can be understood that in other embodiments, the first voice prompt is used for a turn prompt, and specifically, other voices such as "please turn", "turn", "driver please turn", and the like can also be used, and a person skilled in the art can select according to specific working conditions, which will not be repeated here.
[0071] In other embodiments, the second voice prompt is a voice prompt for a left turn or a right turn, for example, "current left turn", "current right turn", "right turn is available", or "left turn is available", and the like, and a person skilled in the art can select according to specific working conditions, which will not be repeated here.
[0072] S11: voice prompt
[0073] The voice technology is used to give a turnable direction prompt, and the specific prompt is S10.
[0074] S12: determining whether the countdown time t is equal to 3s (i.e., a second time threshold, which is selected and set by a person skilled in the art according to specific working conditions, which will not be repeated here);
[0075] According to the determination, a third voice prompt is produced, which is used to prompt that a traffic light is about to change, for example, the third voice prompt can be "the traffic light is about to change, please pay attention to observation", "the red light is about to turn on, please drive carefully", and the like, thereby avoiding missing a turn due to distraction and improving turn driving safety.
[0076] It can be understood that in other embodiments, the third voice prompt can also be the same as the second voice prompt, and a person skilled in the art can select according to specific working conditions, which will not be repeated here.
[0077] S13: determining whether the countdown time t is equal to 0s (i.e., a second time threshold)
[0078] Here, when the countdown time is 0, the step of recalculating the turnable direction by photographing again and re-executing S2-S12 is performed.
[0079] Embodiment 2
[0080] The embodiment 2 of the present application provides a voice-based turn prompting system, which comprises:
[0081] The distance determination module is configured to obtain a distance of a current vehicle from a red traffic light intersection, and when the distance of the current vehicle from the red traffic light intersection is less than a first distance threshold, the next step is performed.
[0082] The signal light recognition module is configured to recognize a signal light to obtain a turnable direction of the signal light and a countdown time of the signal light.
[0083] The turnable direction acquisition module is configured to: acquire the lane where the vehicle is currently located, and obtain the current turnable direction according to the lane where the vehicle is currently located;
[0084] The first turning judgment module is configured to: execute the next step when the possible turning direction of the traffic light is the same as the current possible turning direction and the countdown time of the traffic light is greater than the first time threshold;
[0085] The second turning judgment module is configured to generate a first voice prompt when the signal light's turnable direction and the current turnable direction are the same as the vehicle's turn light direction; otherwise, generate a second voice prompt.
[0086] The working method of the system includes:
[0087] (1) Using a third-party map SDK or ADAS-TLR or camera (image recognition method) to identify roads and turn signals; using a third-party map SDK or ADAS-TLR or image recognition technology to identify road conditions, such as the lane the vehicle is currently in and the turn signal markings on the current lane;
[0088] Use image recognition or third-party navigation map information to obtain the traffic light's turn sign and countdown information; measure the distance between the current vehicle and the red light intersection (this can be achieved by using a third-party map SDK or ADAS-TLR, or by using on-board sensors) so that corresponding photo taking and image recognition functions can be performed based on the distance.
[0089] (2) Determine whether the current vehicle distance to the intersection is less than or equal to 20m (i.e., the first distance threshold)
[0090] This is used to determine whether the current vehicle is less than or equal to 20 meters away from the red light (it can be understood that those skilled in the art can set the first distance threshold according to the specific circumstances of the system design, such as 19 meters, 25 meters, etc., which will not be repeated here). If it is less than or equal to 20 meters, continue to execute the subsequent steps, otherwise return to the previous step.
[0091] (3) Current lane identification
[0092] Use a third-party map (or use on-board sensors or cameras for identification) to identify which lane the vehicle is currently in. This information can be obtained using the corresponding SDK of the third-party map navigation.
[0093] (4) Current turning direction w
[0094] Determine which direction the vehicle can turn when it is in the current road lane. This information can be combined with the lane information and the turn marks on the lane to determine the direction in which the current lane can turn.
[0095] (5) Vehicle turn signal w2
[0096] Record the turn signal of the user's active operation, which indicates the user's subjective intention to turn, for turn prompting.
[0097] (6) Signal recognition
[0098] This embodiment mainly identifies the turn marking and countdown information of the traffic light, and determines which direction the red light allows to turn according to the comparison of the turn of the traffic light.
[0099] The countdown information on the traffic light sign is used to provide data support for the following logical information; this embodiment can use the adas-tlr system or image recognition technology to identify the traffic light signal information.
[0100] (7) Signal light turnable direction w1
[0101] According to the signal recognition system, the traffic light marking is identified, and then the direction that can be turned is determined through calculation.
[0102] (8) Countdown t
[0103] The countdown information of the red light change is identified by the signal recognition system, which can be identified using image recognition technology or obtained by using third-party navigation software.
[0104] (9) (w1&w) && (t>8)
[0105] This judgment is the entry logic of the turn prompting, and is the most important judgment, which is used to judge whether the current lane w1 of the vehicle and the marking recognition of the red light have intersection, that is, whether w1&w is true.
[0106] If it is true and the countdown of the traffic light is greater than 8s (i.e. the first time threshold, 8s is to ensure enough time to pass through the traffic light, this value can also be calculated according to the current speed in the actual system, or selected and set by those skilled in the art according to specific working conditions, for example, 7s, 9s, etc., which will not be repeated here), that is, the turnable direction of the vehicle lane meets the conditions, that is, it can turn.
[0107] (10) w2&w1&w
[0108] If the vehicle's current lane's turning direction w1 (byte array type, because there may be more than one turning direction) matches the turn direction w satisfied by the red light and the vehicle's turn signal w2, and if w2&w1&w are true, then the red light, the lane, and the user's steering intention are consistent, then a voice prompt "Master, master, turn!" (i.e., the first voice prompt) will be used; otherwise, a voice prompt "You can turn left" or "You can turn right" (i.e., the second voice prompt) will be used, where the direction of turn is determined by which of w1&w is true.
[0109] It is understandable that in some other embodiments, the first voice prompt is used for turning prompts, and may specifically be other voice prompts, such as "Please turn", "Turn", "Driver, please turn", etc. Those skilled in the art may select the voice prompt according to specific working conditions, and will not be described in detail here.
[0110] In some other embodiments, the second voice prompt is a prompt tone for turning left or right, such as "Can turn left now", "Can turn right now", "Can turn right" or "Can turn left", etc. Those skilled in the art can choose according to the specific working conditions, which will not be repeated here.
[0111] (11) Voice prompts
[0112] The turn direction prompt is given using voice technology. For specific prompts, see S10.
[0113] (12) Determine whether the countdown t is equal to 3s (i.e., the second time threshold, which is selected and set by those skilled in the art according to specific working conditions and will not be described in detail here);
[0114] Based on this judgment, a third voice prompt can be generated to indicate that the traffic light is about to change. For example, the third voice prompt can be "The traffic light is about to change, please pay attention", "The red light is about to come on, please drive carefully", etc., thereby preventing users from missing turns due to distraction and improving turning driving safety.
[0115] It is understandable that in some other embodiments, the third voice prompt may also be the same as the second voice prompt. Those skilled in the art may make a choice according to specific working conditions, which will not be elaborated here.
[0116] (13) Determine whether the countdown t is equal to 0s (i.e., the second time threshold)
[0117] Here, when the countdown reaches 0, the system takes a new photo and calculates the direction to turn, and then executes steps S2-S12 again.
