As shown in fig. 2, method 200 includes:
step S201, obtaining current vehicle state information of a vehicle, wherein the current vehicle state information comprises a current vehicle position and a current vehicle speed of the vehicle;
step S202, signal lamp information related to the current vehicle position of the vehicle is obtained;
step S203, acquiring road condition information corresponding to the current vehicle position; and
step S204, providing early warning information for the vehicle at least based on the current vehicle state information, the signal lamp information and the road condition information of the vehicle, wherein the early warning information at least prompts the vehicle to avoid violating the signal lamp indication.
Therefore, aiming at the problem that the traditional automobile can not obtain various convenient user experiences caused by intelligent transportation basically, the method can endow the traditional vehicle with intelligent transportation capacity such as light running early warning and the like, and effectively improves various convenient user experiences obtained from intelligent transportation infrastructure when the traditional vehicle participates in road transportation from the perspective of a vehicle end.
In the technical solution of the present disclosure, the acquisition, storage, application, and the like of the personal information of the related user all conform to the regulations of the related laws and regulations, and do not violate the customs of the public order. It should also be noted that, in the present disclosure, the information such as the current vehicle state information is obtained only for the purpose of providing warning information (e.g., signal light warning information) to the vehicle, and is obtained after being provided by user authorization (i.e., user authorization is verified). In addition, the obtained information such as the current vehicle state information is not intended to characterize a specific type of user (e.g., the owner of a specific vehicle type), and thus does not reflect personal information of a specific type of user.
The various steps of method 200 are described in detail below.
In step S201, current vehicle state information of the vehicle is acquired.
According to an embodiment of the present disclosure, the current vehicle state information includes a current vehicle position and a current vehicle speed of the vehicle.
According to an embodiment of the present disclosure, current vehicle state information such as a geographic position (longitude and latitude), a vehicle speed, and a driving direction of a vehicle may be collected in real time or periodically.
In step S202, signal light information related to the current vehicle position of the vehicle is acquired.
It is understood that the signal light is related to the current vehicle position of the vehicle, meaning that the vehicle is travelling towards the signal light on the road on which the signal light is arranged.
According to an embodiment of the present disclosure, acquiring signal light information related to a current vehicle position of the vehicle includes: determining a next intersection to which the vehicle will travel based on the obtained current vehicle position of the vehicle and the direction of the current vehicle speed; and acquiring the current signal lamp state information of the signal lamp of the determined next intersection. Specifically, the current signal lamp state information includes a current state of the signal lamp and a remaining display time. Thereby, an overview of the signal lights of the next intersection on the vehicle travel route can be obtained to facilitate accurate generation of signal light warning information intended to be provided to a vehicle user (e.g., driver).
In step S203, the traffic information corresponding to the current vehicle position is obtained.
It is understood that the traffic information corresponding to the current vehicle position refers to information related to each traffic participant within a road segment that is a preset distance away from the vehicle in the vehicle traveling direction, and includes, but is not limited to, a lane in which the vehicle is located, information related to a preceding vehicle on the lane in which the vehicle is located, information related to a preceding accident on the lane in which the vehicle is located, information related to a lane adjacent to the lane in which the vehicle is located, and the like.
According to an embodiment of the present disclosure, the length range of the road section that is a preset distance from the vehicle in the vehicle traveling direction as described above may be set to be comparable to the field of view range of the vehicle user (e.g., driver), or may be set to be as long as the next intersection of the current lane in the vehicle traveling direction (e.g., considering that the lane is a tidal lane), and so on.
In step S204, the vehicle is provided with warning information.
According to an embodiment of the present disclosure, early warning information is provided to the vehicle based on at least current vehicle state information, the signal light information, and the road condition information of the vehicle. The early warning information at least prompts the vehicle to avoid violating signal light indications.
Thus, in response to the problem that the conventional automobile cannot substantially obtain various convenient user experiences brought by intelligent transportation, the conventional vehicle can be endowed with intelligent transportation capabilities such as early warning of light running and the like by acquiring and aggregating the vehicle information and information from other transportation participants (e.g., signal lights for directing traffic, other motor vehicles participating in road traffic, etc.). From the perspective of vehicle end, the method effectively improves various convenient user experiences obtained by the traditional vehicle from the intelligent traffic infrastructure when participating in road traffic, so that the traditional vehicle can obtain the intelligent traffic capacity possessed by the intelligent vehicle (for example, a vehicle with the capacity of V2V, V X and the like) only by minor modification, and the traditional vehicle does not need to be carried with a complete set of elaborate hardware and software components which are specially used for intelligent traffic and have higher cost and are equipped with the intelligent vehicle.
In addition, the calculation of the light-running early warning event is transferred to the vehicle end, so that adverse effects such as switching of a base station and network jitter of a terminal are avoided, and effectiveness and accuracy of the early warning event are guaranteed.
According to an embodiment of the present disclosure, providing early warning information to the vehicle based on at least the current vehicle state information, the signal light information, and the road condition information of the vehicle includes: generating early warning information for providing to the vehicle based on the current vehicle state information, the signal lamp information and the road condition information of the vehicle; acquiring a first distance between the current vehicle position of the vehicle and the determined next intersection; and in response to the first distance exceeding a first preset threshold, not providing the early warning information to the vehicle. During actual road driving traffic, for example, if the vehicle is too far away from a road junction, it may be a hurry to provide a user of the vehicle (e.g., a driver) with warning information about a signal light at the road junction ahead. For another example, when the forward intersection signal lamp cannot be seen in the field of view of the driver of the vehicle (and thus it is not possible to determine whether the driver has a driving behavior tending to break the lamp), it may not be appropriate to provide the user of the vehicle (e.g., the driver) with warning information about the forward intersection signal lamp. Therefore, the frequency of providing the early warning information is relaxed and is more suitable for the actual operation of the vehicle user, so that the unexpected situation that the vehicle is too far away from the road junction or the signal lamp is not in the visible field of the vehicle user and the early warning prompt about the signal lamp at the front road junction is provided for the vehicle user is effectively avoided.
According to the embodiment of the disclosure, the first preset distance may be set based on factors such as historical behavior habits of a vehicle user (e.g., historical driving behavior reacting to a crossing signal light), preferences of the vehicle user (e.g., an amount of time advance expected to receive a signal light warning prompt about a crossing ahead), ground conditions of a current road section (e.g., a shortest braking distance corresponding to an upper vehicle speed limit of the current road section), and the like.
According to an embodiment of the present disclosure, providing early warning information to the vehicle based on at least the current vehicle state information, the signal light information, and the road condition information of the vehicle includes: and responding to the first distance not exceeding a first preset threshold value, and providing the early warning information to the vehicle. Therefore, the warning information about the intersection signal lamp can be timely provided for the vehicle user when the vehicle leaves the safety range and enters the road section area needing attention to the intersection signal lamp in a desirable mode, the invalidity of information caused by early providing of the warning information is avoided, and the effectiveness of the warning information is improved.
According to an embodiment of the present disclosure, the current state of the signal lamp at the next intersection is a red light, and providing the vehicle with the warning information based on at least the current vehicle state information of the vehicle, the signal lamp information, and the road condition information further includes: generating early warning information for providing to the vehicle based on the current vehicle state information, the signal lamp information and the road condition information of the vehicle; acquiring a first distance between the current vehicle position of the vehicle and the determined next intersection; and in response to the time taken for the vehicle to travel the first distance at the current vehicle speed being greater than the remaining display time of the signal lights, not providing the early warning information to the vehicle. Generally, in the case of a red light violation, the vehicle speed of the vehicle violating the red light signal indication is generally high, for example, around or far above a prescribed upper vehicle speed limit at the intersection (e.g., for rapid crossing). Thus, during actual road driving traffic, if the vehicle speed is so slow (e.g., due to administrative restrictions on the upper limit of the road speed or because of driving behavior habits of the vehicle driver himself, etc.) that the vehicle can be braked in a short distance in time without causing safety hazards to the occupants of the vehicle, it is not necessary to provide warning information about the intersection signal lights to the vehicle user. Therefore, the warning information about the signal lamp can be avoided being provided under the condition that the vehicle speed is too low to brake in time in a desirable mode, the user bad experience caused by providing the warning information under the condition is avoided, and the pertinence of the warning information is improved.
According to an embodiment of the present disclosure, providing early warning information to the vehicle based on at least the current vehicle state information, the signal light information, and the road condition information of the vehicle includes: providing the warning information to the vehicle in response to the time taken for the vehicle to travel the first distance at the current vehicle speed not being greater than the remaining display time of the signal lights. Typically, no storage or caching device capable of recording behavioral habits of a vehicle user (e.g., driver) is equipped on a conventional vehicle. Thus, when it is determined that there is a case where the signal light does not become a green light pass while traveling to the intersection at the existing vehicle speed, it is necessary to provide the vehicle with the warning information about the signal light at the intersection in a more robust manner. Therefore, the warning information about the signal lamp can be provided in a desirable mode under the condition that the vehicle speed is too high to judge whether the driver violates the indication of the signal lamp from the perspective of the traditional vehicle, and the effective coverage of the warning information on the potential dangerous scene is improved.
According to an embodiment of the present disclosure, the current vehicle state information further includes brake state information of the vehicle. Providing early warning information to the vehicle based at least on the current vehicle state information, the signal light information, and the road condition information of the vehicle comprises: generating early warning information for providing to the vehicle based on the current vehicle state information, the signal lamp information and the road condition information of the vehicle; and in response to the braking state information indicating that the vehicle is currently braking, not providing the warning information to the vehicle. When detecting that the user is actively braking in front of the intersection, the risk of additionally reminding the user of running the light is avoided, because the user is likely to be actively braking to avoid the occurrence of the behavior of running the light. Therefore, when the fact that the vehicle driver actively steps on the brake to brake the vehicle is detected, the transmission link of the early warning information is timely disconnected, bad experience brought to a vehicle user by an excessively cautious warning information transmission mechanism is avoided, and effectiveness and pertinence of the early warning information are further improved.
According to an embodiment of the present disclosure, providing early warning information to the vehicle based on at least the current vehicle state information, the signal light information, and the road condition information of the vehicle includes: providing the early warning information to the vehicle in response to the braking state information indicating that the vehicle is not currently braking.
It can be understood that as an effective evasion means of the light running behavior, the brake braking is the only effective measure that the vehicle driver can take in most cases. Therefore, under the condition that the braking behavior of the vehicle is not detected, the early warning information is provided for the vehicle in a robust mode, and the effective coverage of the early warning information on a potential dangerous scene can be improved.
Whether a conventional vehicle or a smart vehicle, the state of the vehicle participating in road traffic may be roughly classified as an familiar road cruising state (i.e., the vehicle is on a daily commute or travels a road segment that is familiar to the driver of the vehicle without navigating with navigation means) or a navigational state (e.g., the vehicle is traveling a road segment that is relatively unfamiliar to the driver of the vehicle such that the driver needs to navigate to a desired destination with navigation means).
According to an embodiment of the present disclosure, the current vehicle state information further includes driving state information of the vehicle, the driving state information indicates that the vehicle is in an overtaking cruising state, and a lane where the vehicle is currently located is an established lane that the vehicle is currently following in the overtaking cruising state. Acquiring the determined current signal lamp state information of the signal lamp of the next intersection comprises acquiring the current signal lamp state information of the signal lamp corresponding to the current lane of the vehicle in the signal lamp of the next intersection. Therefore, when the vehicle is determined to run in the familiar road cruising state, the early warning information generated for the vehicle can be associated with the established lane followed by the vehicle in the familiar road cruising state, so that the pertinence of the early warning information is effectively improved.
In the navigation mode (e.g., the vehicle is traveling on a section of road that is unknown to the driver), the user need only be concerned with the signal light indication of the lane in which the vehicle is located, and need not be concerned with the forward signal light on the adjacent lane, provided that the vehicle is following the navigation route without a wrong-way lane being opened.
According to an embodiment of the present disclosure, the current vehicle state information further includes driving state information of the vehicle, the driving state information indicating that the vehicle is in a navigation state. Further, the obtaining of the road condition information corresponding to the current vehicle position includes obtaining a current lane of the vehicle. Acquiring the current signal lamp state information of the signal lamp of the determined next intersection comprises the following steps: and responding to the fact that the current lane of the vehicle does not deviate from the navigation route of the vehicle, and acquiring the current signal lamp state information of the signal lamp corresponding to the current lane of the vehicle in the signal lamps of the next intersection. Therefore, the relevance between the early warning information generated for the vehicle in the navigation running state of the vehicle and the lane where the vehicle runs correctly in the navigation state can be ensured, and the pertinence of the early warning information is effectively improved.
However, in the navigation mode, the vehicle driver may miss a lane by being too attentive on the navigation interface, e.g., driving the lane onto an adjacent lane adjacent to the correct lane as indicated by the navigation application.
According to the embodiment of the present disclosure, obtaining the current signal lamp state information of the signal lamp of the determined next intersection further includes: and acquiring current signal lamp state information of signal lamps corresponding to the lanes which the vehicle can possibly pass through before the next intersection along the current lane in the signal lamps of the next intersection in response to the fact that the current lane of the vehicle deviates from the navigation route of the vehicle.
It will be appreciated that if the vehicle has deviated from the intended lane of navigation, the vehicle will by default continue to travel in the wrong lane. Thus, there may be a variety of possibilities for the vehicle to pass along the lane that the current lane may be in before the next intersection, depending on whether the wrong lane driven by the vehicle diverges before the intersection. Also, therefore, the current signal light state information of the signal light acquired in this case may include signal light state information corresponding to a plurality of lanes derived from the currently-traveling wrong-way.
According to an embodiment of the present disclosure, providing early warning information to the vehicle based on at least the current vehicle state information, the signal light information, and the road condition information of the vehicle further includes: generating early warning information for providing to the vehicle based on the current vehicle state information, the signal lamp information and the road condition information of the vehicle; acquiring intersection queuing information corresponding to a current lane of the vehicle; and in response to the intersection queuing information indicating that the queuing distance before the stop line of the next intersection exceeds a second preset threshold, not providing the early warning information to the vehicle. From this, can in time avoid providing the early warning information about the signal lamp to the vehicle under the condition that the vehicle is detained in line appearing before the front crossing stop line, avoid dispersion vehicle user's attention, make it to more be absorbed in the vehicle and travel and should keep safe distance with the front truck when blocking up the highway section to help promoting user experience and driving safety nature.
According to an embodiment of the present disclosure, the current state of the signal lamp at the next intersection is a green lamp, and providing the vehicle with the warning information at least based on the current vehicle state information of the vehicle, the signal lamp information, and the road condition information further includes: generating early warning information for providing to the vehicle based on the current vehicle state information, the signal lamp information and the road condition information of the vehicle; and responding to the intersection queuing information to indicate that queuing exists beyond the stop line of the next intersection, providing the early warning information for the vehicle, and prompting that the green light is blocked from passing by the early warning information.
It will be appreciated that when the crossroad traffic is congested ahead, vehicles should stop sequentially outside the crossroad to wait without entering the crossroad, otherwise orderly passage of vehicles (i.e., green light running behavior) may result from lanes in a direction orthogonal to the current lane of the vehicle. Therefore, the risk of green light running of the vehicle can be avoided by considering vehicle queuing confidence except for the stop line, and effective avoidance of the unusual traffic violation scenes except for the scenes with potential safety hazards is further improved.
According to the embodiment of the present disclosure, the obtaining of the road condition information corresponding to the current vehicle position further includes obtaining vehicle state information of a preceding vehicle, where the preceding vehicle runs on a current lane of the vehicle and is in front of a stop line of the next intersection, and the method further includes, based on at least the current vehicle state information of the vehicle, the signal lamp information, and the road condition information, providing early warning information to the vehicle: generating early warning information for providing to the vehicle based on the current vehicle state information of the vehicle, the signal lamp information and the road condition information; when the vehicle state information of the preceding vehicle indicates that the preceding vehicle is currently braked, the early warning information is provided for the vehicle, and the early warning information prompts the vehicle that the possibility that a green light cannot pass exists. Thus, when a situation occurs in which the preceding vehicle does not pass through the intersection with a green light (for example, braking ahead of the stop line in advance in the case of a signal light green light due to excessive caution in the driving behavior of the driver of the preceding vehicle, braking having to occur in the preceding vehicle due to a mechanical or electronic failure, or the like), the payload of the warning information can be further improved by taking into account the vehicle speed information of the preceding vehicle.
According to the embodiment of the disclosure, the acquiring of the road condition information corresponding to the current vehicle position further includes acquiring front accident state information, and the method of providing the vehicle with the early warning information at least based on the current vehicle state information of the vehicle, the signal lamp information and the road condition information further includes: generating early warning information for providing to the vehicle based on the current vehicle state information, the signal lamp information and the road condition information of the vehicle; responding to the front accident state information to indicate that an accident occurs in front of the current lane of the vehicle, providing the early warning information for the vehicle, and prompting the vehicle to avoid violating signal light indications corresponding to the current lane and the lane after lane change. It can be appreciated that when an accident occurs in front of the lane, the vehicle needs to change lanes to bypass the accident site. Therefore, it is necessary to simultaneously display the warning of light running of the traffic light corresponding to the lane after lane change and the warning of light running of the traffic light corresponding to the current lane in order to allow for the vehicle to quickly return to the original lane after lane change.
According to the embodiment of the disclosure, at least based on the current vehicle state information, the signal lamp information and the road condition information of the vehicle, the method for providing early warning information to the vehicle further comprises the following steps: generating early warning information for providing to the vehicle based on the current vehicle state information, the signal lamp information and the road condition information of the vehicle; when the current vehicle speed of the vehicle is accelerated so as to pass through the next intersection within the remaining display time of the signal lamp, the warning information is not provided to the vehicle. Thus, redundant triggering of the warning information is circumvented by taking into account the actual driving behavior of the vehicle driver actively speeding up in the hope of passing through the intersection in the green light window, and thus distraction of the driver's attention when quickly passing through the intersection is avoided.
According to an embodiment of the present disclosure, any of the above embodiments may further include displaying the provided warning information, wherein the warning information is slidably overlaid on the interactive interface of the vehicle. Therefore, the user can be supported to drag randomly, so that the interface area which the user desires to interact with is not blocked.

The cloud control platform 320 may send drive test information (which may include traffic light information, perception data, etc. transmitted by the roadside RSCU device 350) to the end device 310 based on the request (e.g., upon an acquisition request by the end device 310). Meanwhile, the cloud control platform 320 transmits the position information and the like transmitted by the terminal device 310 and the traffic light information, the perception data and the like transmitted by the roadside RSCU device 350 to the cloud control platform 320 via the redis 330 to the kafka 340, which transmits the data to the internet connection service 360. The networking service 360 integrates and processes the received information to form and transmit the rich link information, queue length information, and the like to the terminal device 310 (e.g., upon an acquisition request of the terminal device 310).
Thus, the terminal device 310 may generate warning information for prompting the vehicle user based on its own location information, the received drive test information, and the road condition information (i.e., the familiar road information, the queuing length information) provided by the internet service 360, and the like.
