[0002] In some traffic scenarios, dangerous situations may occur when the door of a vehicle is opened after the vehicle has been parked, for example, another traffic participant is too close to the door or another traffic participant collides with the door. Such dangerous situations may sometimes occur due to the negligence of the driver of the vehicle or other passengers of the vehicle, the position of another traffic participant being exactly in the blind area of the person who opens the door, or another traffic participant being hardly able to be detected for having a relatively small size and / or being unable to react in the case of a relatively fast speed, etc. Here, another traffic participant may be, for example, a motor vehicle, a motorcycle, an electric bicycle, a bicycle, a scooter, or a pedestrian, etc. A vehicle-mounted sensor (e.g. a radar sensor, a camera, etc.) is often unable to effectively avoid the above dangerous situations.

DE 10 2016 215478 A1 provides a method for warning road users in an environment of a motor vehicle of imminent disembarkation of one or more motor vehicle occupants of the motor vehicle. US 2017 / 218678 A1 provides a method for preventing vehicle door related accidents will help to detect oncoming traffic and / or nearby external objects when an occupant of the vehicle or the vehicle processor demonstrates an intent to open the vehicle door.Summary of the Invention

[0004] The present invention is set out by the appended claims.

[0005] An object of the present invention is to provide a method and apparatus for improving the traffic safety for a vehicle, which can give a pre-warning of or prevent dangerous situations when the door is opened after a vehicle has been parked. In addition, a further object of the present invention is to provide a method and apparatus for improving the traffic safety for an infrastructure, which can give, particularly based on a current traffic condition, a pre-warning of dangerous situations when the door of a vehicle is opened after the vehicle in the environment surrounding the infrastructure has been parked.

[0006] To this end, according to a first aspect of the present invention, a method for improving the traffic safety for a vehicle is provided, as defined by independent claim 1. The method comprises the following steps: sending a parking safety request to an infrastructure; receiving pre-warning information that is sent by the infrastructure in response to the parking safety request; detecting a safety trigger event if the pre-warning information indicates that the opening of the door of the vehicle will result in a dangerous situation; and triggering safety measures where the safety trigger event is detected. The parking safety request is sent to the infrastructure where a parking intention for the vehicle is detected. The parking intention for the vehicle is detected when at least one of the following situations occurs: the presence of a parking space being detected, and it being detected that the distance between the vehicle and the parking space is less than a predetermined distance threshold; and the presence of the parking space being detected, and it being detected that a time when a driver's attention is focused on the parking space exceeds a predetermined time threshold. The pre-warning information includes a type of other traffic participant that is to collide with the opened door and / or an expected time for collision.

[0007] The solutions may be particularly based on the following considerations: it is ascertained, based on the pre-warning information from the infrastructure rather than environment information detected by the vehicle itself, whether a dangerous situation will occur when the door is opened; and after the pre-warning information sent by the infrastructure is received, the safety measures are not directly triggered, but triggered only when a corresponding safety trigger event is detected.

[0008] Herein, the infrastructure is, for example, a roadside unit (RSU). The infrastructure can particularly detect a surrounding environment. For example, the infrastructure may be equipped with a camera apparatus, an ultrasonic sensor, a radar, etc. The infrastructure can communicate with an object, particularly a vehicle, in the surrounding environment. The communication can be performed based on any suitable communication protocol, for example, a PC5 protocol, an IEEE 802.11p protocol, etc. Optionally, the infrastructure can further communicate with an external server (particularly a cloud server) based on any suitable communication protocol. The infrastructure can further calculate features about a traffic scenario in the surrounding environment based on detected data and / or received data, particularly according to specific tasks. In addition, the infrastructure can further have a storage function.

[0009] In one embodiment of the present invention, the dangerous situation is that the distance between another traffic participant and the door is less than a predetermined distance threshold or that another traffic participant collides with the door. Herein, the predetermined distance threshold may be less than 3 metres, for example, it may be 2.5 metres, particularly 1.5 metres.

[0010] Herein, the first speed threshold is less than 10 kilometres per hour, for example, 7 kilometres per hour, particularly 5 kilometres per hour. Herein, the distance threshold is less than 5 metres, for example, it may be 3 metres, particularly 1.5 metres. Herein, the time threshold is greater than 0.5 minutes, for example, it may be 1 minute, particularly 1.5 minutes.

[0011] The above situations are merely exemplary, and do not mean that all situations where the parking intention is detected are exhaustive.

[0051] The preferred embodiments of the present invention are described below in detail based on the accompanying drawings. Those skilled in the art should understand that these preferred embodiments are merely exemplary and are not intended to limit the present invention in any manner. FIG. 1 shows a schematic flowchart of a method for improving the traffic safety for a vehicle according to the present invention. FIG. 2 shows a schematic flowchart of a method for improving the traffic safety for an infrastructure according to the present invention.

[0052] FIG. 1 shows a schematic flowchart of a method for improving the traffic safety for a vehicle according to the present invention. The method is implemented on a vehicle side, for example, in a scenario where a vehicle is temporarily parked or where the vehicle is parked in a parking space.

[0053] In a first method step 101, a parking safety request is sent to an infrastructure.

[0054] Herein, the parking safety request is particularly automatically sent to the infrastructure where a parking intention for a vehicle is detected.

[0055] For example, the parking intention for the vehicle is detected when at least one of the following situations occurs: an automatic parking function or a semi-automatic parking function being enabled; the speed of the vehicle being less than a predetermined first speed threshold; the presence of a parking space being detected, and it being detected that the distance between the vehicle and the parking space is less than a predetermined distance threshold; the presence of the parking space being detected, and it being detected that a time when a driver's attention is focused on the parking space exceeds a predetermined time threshold; a transmission of the vehicle being placed in a parking gear; and a parking brake of the vehicle being placed in a parking position.

[0056] Herein, the first speed threshold is less than 10 kilometres per hour, for example, 7 kilometres per hour, particularly 5 kilometres per hour.

[0057] Herein, the distance threshold is less than 5 metres, for example, it may be 3 metres, particularly 1.5 metres.

[0058] Herein, the time threshold is greater than 0.5 minutes, for example, it may be 1 minute, particularly 1.5 minutes.

[0059] The above situations are merely exemplary, and do not mean that all situations where the parking intention is detected are exhaustive.

[0060] In a second method step 102, pre-warning information sent by the infrastructure in response to the parking safety request is received.

[0061] Herein, the pre-warning information particularly indicates whether the opening of the door of the vehicle will result in a dangerous situation, particularly the door colliding with another traffic participant. For example, the pre-warning information can indicate one of the following situations where the opening of the door will result in a dangerous situation, particularly colliding with another traffic participant; and the opening of the door will not result in a dangerous situation, particularly colliding with another traffic participant. For example, the pre-warning information only indicates that the opening of the door will result in a dangerous situation, particularly colliding with another traffic participant.

[0062] In addition, the pre-warning information may further comprise other information, for example, the type of other traffic participant that is to collide with the opened door and / or an expected time for collision, etc.

[0063] In a third method step 103, a safety trigger event is detected if the pre-warning information indicates that the opening of the door of the vehicle will result in a dangerous situation.

[0064] The safety trigger event is detected when at least one of the following situations occurs: it being detected that the door of the vehicle is to be opened; the automatic parking function or the semi-automatic parking function being ended; the speed of the vehicle being lowered to 0; a transmission of the vehicle being placed in a parking gear; and a parking brake of the vehicle being placed in a parking position. The above situations are merely exemplary, and do not mean that all situations where the safety trigger event is detected are exhaustive.

[0065] The safety trigger event can be detected by reading the state of a corresponding functional unit and / or by using a corresponding sensor apparatus.

[0066] In a fourth method step 104, safety measures are triggered where the safety trigger event is detected. Herein, the safety measures give, to the participants of the vehicle, a warning that the opening of the door will cause danger and / or hinder, or even stop the participants of the vehicle from opening the door.

[0067] For example, the safety measures comprise at least one of the following measures: outputting an audio warning signal; outputting a video warning signal; and outputting a tactile warning signal.

[0068] For example, warning information is displayed on a display apparatus in the vehicle and / or a light emitting apparatus in the vehicle flashes at a predetermined frequency to give a warning and / or a sound producing apparatus in the vehicle produces a predetermined tone or voice to give a warning. Alternatively or additionally, a warning is given with the damping for which the door is opened being greater than a predetermined damping threshold. Preferably, a warning is given with the door being locked upon the first attempt to open the door.

[0069] Optionally, pre-warning information sent by the infrastructure in response to the parking safety request is periodically received until a sending end condition is satisfied. Herein, the detection of a safety trigger event is to be carried out only if the received pre-warning information indicates that the opening of the door of the vehicle will result in a dangerous situation, and safety measures are triggered where the safety trigger event is detected. In this way, the safety and reliability can be further improved.

[0070] Optionally, a pre-warning end request is sent to the infrastructure where the sending end condition is satisfied. For example, the sending end condition is satisfied when at least one of the following situations occurs: the safety trigger event being detected; the speed of the vehicle being greater than a predetermined second speed threshold; the acceleration of the vehicle is greater than a predetermined acceleration threshold; and the vehicle leaving a predetermined area, particularly the parking space where the vehicle is located. The above situations are merely exemplary, and do not mean that all situations of the sending end condition are exhaustive.

[0071] Herein, the second speed threshold is greater than 10 kilometres per hour, for example, 15 kilometres per hour, particularly 18 kilometres per hour.

[0072] Herein, the acceleration threshold is greater than or equal to 0 metre per second squared.

[0073] Herein, the predetermined area may be, for example, the parking space where the vehicle is located or a part of the parking space or a predetermined area on the edge of the road.

[0074] According to the present invention, after the pre-warning information sent by the infrastructure is received, the safety measures are not directly triggered for implementation, but triggered only when a corresponding safety trigger event is detected.

[0075] FIG. 2 shows a schematic flowchart of a method for improving the traffic safety for an infrastructure according to the present invention. The method is implemented on an infrastructure side, for example, when a vehicle is temporarily parked or the vehicle is parked in a parking space in the environment surrounding the infrastructure.

[0076] In a first method step 201, a parking safety request from a vehicle is received.

[0077] In a second method step 202, pre-warning information is generated based on a current traffic condition, particularly in response to the parking safety request. The pre-warning information can at least indicate that the opening of the door of the vehicle will result in a dangerous situation.

[0078] In a third method step 203, the pre-warning information is sent to the vehicle.

[0079] Herein, the infrastructure can receive feature information of a traffic participant in the environment surrounding the infrastructure. The feature information includes, for example, the type of the traffic participant and / or the position of the traffic participant and / or the moving direction of the traffic participant and / or the speed of the traffic participant and / or the acceleration of the traffic participant. The pre-warning information for the vehicle can be generated based on feature information received from the vehicle and feature information received from another traffic participant.

[0080] Herein, the dangerous situation is, for example, that the distance between another traffic participant and the door is less than a predetermined distance threshold or that another traffic participant collides with the door. Herein, the predetermined distance threshold may be less than 3 metres, for example, it may be 2.5 metres, particularly 1.5 metres.

[0081] For example, the pre-warning information can indicate one of the following situations where the opening of the door will result in a dangerous situation about the door, particularly colliding with another traffic participant; and the opening of the door will not result in a dangerous situation, particularly the door colliding with another traffic participant. Optionally, the pre-warning information only indicates that the opening of the door will result in a dangerous situation, particularly colliding with another traffic participant.

[0082] In addition, the pre-warning information may further comprise other information, for example, the type of other traffic participant that is to collide with the opened door and / or an expected time for collision, etc.

[0083] Optionally, the pre-warning information is periodically generated based on the current traffic condition, particularly in response to the parking safety request, until a pre-warning end request sent by the vehicle is received. The length of the period may be constant or may be dynamically changing according to the current traffic condition.

[0084] FIG. 3 shows a schematic block diagram of an apparatus for improving the traffic safety for a vehicle according to the present invention. The apparatus for improving the traffic safety for a vehicle according to the present invention is particularly arranged in a vehicle.

[0085] Herein, the apparatus 3 for improving the traffic safety for a vehicle according to the present invention comprises a sending module 301, a receiving module 302, a safety trigger event detection module 303, and a safety measure trigger module 304. The sending module 301 is configured to send a parking safety request to an infrastructure. The receiving module 302 is configured to receive pre-warning information that is sent by the infrastructure in response to the parking safety request. The safety trigger event detection module 303 is configured to detect a safety trigger event if the pre-warning information indicates that the opening of the door of the vehicle will result in a dangerous situation. The safety measure trigger module 304 is configured to trigger safety measures where the safety trigger event is detected.

[0086] For example, the sending module 301 is configured to send the parking safety request to the infrastructure where a parking intention for the vehicle is detected.

[0087] Optionally, the apparatus 3 for improving the traffic safety for a vehicle according to the present invention further comprises a parking intention detection module (not shown). The parking intention detection module is configured to detect the parking intention for the vehicle when at least one of the following situations occurs: an automatic parking function or a semi-automatic parking function being enabled; the speed of the vehicle being less than a predetermined first speed threshold; the presence of a parking space being detected, and it being detected that the distance between the vehicle and the parking space is less than a predetermined distance threshold; the presence of the parking space being detected, and it being detected that a time when a driver's attention is focused on the parking space exceeds a predetermined time threshold; a transmission of the vehicle being placed in a parking gear; and a parking brake of the vehicle being placed in a parking position. The above situations are merely exemplary, and do not mean that all situations where the parking intention is detected are exhaustive.

[0088] Herein, the first speed threshold is less than 10 kilometres per hour, for example, 7 kilometres per hour, particularly 5 kilometres per hour. The distance threshold is less than 5 metres, for example, it may be 3 metres, particularly 1.5 metres. The time threshold is greater than 0.5 minutes, for example, it may be 1 minute, particularly 1.5 minutes.

[0089] Herein, the dangerous situation is, for example, that the distance between another traffic participant and the door is less than a predetermined distance threshold or that another traffic participant collides with the door. Herein, the predetermined distance threshold may be less than 3 metres, for example, it may be 2.5 metres, particularly 1.5 metres.

[0090] For example, the pre-warning information particularly indicates whether the opening of the door of the vehicle will result in a dangerous situation, particularly the door colliding with another traffic participant. For example, the pre-warning information can indicate one of the following situations where the opening of the door will result in a dangerous situation, particularly colliding with another traffic participant; and the opening of the door will not result in a dangerous situation, particularly colliding with another traffic participant. For example, the pre-warning information only indicates that the opening of the door will result in a dangerous situation, particularly colliding with another traffic participant. In addition, the pre-warning information may further comprise other information, for example, the type of other traffic participant that is to collide with the opened door and / or an expected time for collision, etc.

[0091] For example, the safety trigger event detection module is configured to detect the safety trigger event when at least one of the following situations occurs: it being detected that the door of the vehicle is to be opened; the automatic parking function or the semi-automatic parking function being ended; the speed of the vehicle being lowered to 0; a transmission of the vehicle being placed in a parking gear; and a parking brake of the vehicle being placed in a parking position. The above situations are merely exemplary, and do not mean that all situations where the safety trigger event is detected are exhaustive.

[0092] For example, the safety measures comprise at least one of the following measures: outputting an audio warning signal; outputting a video warning signal; and outputting a tactile warning signal.

[0093] For example, the safety measure trigger module 304 is configured to enable warning information to be displayed on a display apparatus in the vehicle and / or a light emitting apparatus in the vehicle to flash at a predetermined frequency to give a warning and / or a sound producing apparatus in the vehicle to produce a predetermined tone or voice to give a warning. Alternatively or additionally, the safety measure trigger module 304 is configured to enable a warning to be given with the damping for which the door is opened being greater than a predetermined damping threshold. Preferably, the safety measure trigger module 304 is configured to enable a warning to be given with the door being locked upon the first attempt to open the door.

[0094] For example, the receiving module is configured to periodically receive the pre-warning information that is sent by the infrastructure in response to the parking safety request until a sending end condition is satisfied. Herein, the sending module is particularly configured to send a pre-warning end request to the infrastructure where the sending end condition is satisfied.

[0095] Optionally, the sending end condition is satisfied when at least one of the following situations occurs: the safety trigger event being detected; the speed of the vehicle being greater than a predetermined second speed threshold; the acceleration of the vehicle being greater than a predetermined acceleration threshold; and the vehicle leaving a predetermined area, particularly the parking space where the vehicle is located. The above situations are merely exemplary, and do not mean that all situations of the sending end condition are exhaustive.

[0096] Optionally, the apparatus 3 for improving the traffic safety for a vehicle according to the present invention further comprises a storage module (not shown). The storage module is configured to store the received pre-warning information.

[0097] FIG. 4 shows a schematic block diagram of an apparatus for improving the traffic safety for an infrastructure according to the present invention. The apparatus for improving the traffic safety for an infrastructure according to the present invention is particularly arranged in an infrastructure.

[0098] Herein, the apparatus 4 for improving the traffic safety for an infrastructure according to the present invention comprises a receiving module 401, a pre-warning information generation module 402, and a sending module 403. The receiving module 401 is configured to receive a parking safety request from a vehicle. The pre-warning information generation module 402 is configured to generate pre-warning information based on a current traffic condition, particularly in response to the parking safety request. Herein, the pre-warning information can at least indicate that the opening of the door of the vehicle will result in a dangerous situation. The sending module 403 is configured to send the pre-warning information to the vehicle.

[0099] Herein, the dangerous situation is, for example, that the distance between another traffic participant and the door is less than a predetermined distance threshold or that another traffic participant collides with the door. Herein, the predetermined distance threshold may be less than 3 metres, for example, it may be 2.5 metres, particularly 1.5 metres.

[0100] For example, the pre-warning information can indicate one of the following situations where the opening of the door will result in a dangerous situation, particularly the door colliding with another traffic participant; and the opening of the door will not result in a dangerous situation, particularly the door colliding with another traffic participant. Optionally, the pre-warning information only indicates that the opening of the door will result in a dangerous situation, particularly colliding with another traffic participant. In addition, the pre-warning information may further comprise other information, for example, the type of other traffic participant that is to collide with the opened door and / or an expected time for collision, etc.

[0101] For example, the receiving module 401 is further configured to receive feature information of a traffic participant in the environment surrounding the infrastructure. The feature information particularly includes the type of the traffic participant and / or the position of the traffic participant and / or the moving direction of the traffic participant and / or the speed of the traffic participant and / or the acceleration of the traffic participant.

[0102] Optionally, the pre-warning information generation module 402 is configured to generate the pre-warning information based on feature information received from the vehicle and feature information received from another traffic participant.

[0103] Optionally, the pre-warning information generation module 402 is configured to periodically generate the pre-warning information based on the current traffic condition, particularly in response to the parking safety request, until the receiving module receives a pre-warning end request sent by the vehicle. Herein, the length of the period may be constant or may be dynamically changing according to the current traffic condition.
