Method for placing an emergency call in a vehicle

Abstract

The invention relates to a method for placing an emergency call in a vehicle, wherein, when an emergency number is being dialled by means of a mobile terminal, a user interface (1) having an input mask appears on the mobile terminal or on a secondary display of the vehicle and requests the input or correction of the following features: - caller identity, which is adopted from a driver card of a tachograph (2), from a presently selected driver profile, or from personal data available on the mobile terminal, - emergency location, the coordinates of which are determined by means of a global satellite navigation system (3) of the vehicle or of the mobile terminal and are adopted in the mask, wherein a cartographic description of the emergency location is supplemented on the basis of data from a digital map (4), - number of persons affected, - number of occupants of the vehicle, ascertained by seat occupancy detection and / or seatbelt detection and by means of an interior compartment camera, and - situation description, wherein situation images of an exterior region of the vehicle are recorded by means of cameras (5.1, 5.2, 5.3) situated on the vehicle, wherein the user interface (1) is configured such that the connection to the emergency number can be ended only by way of an at least double confirmation, and wherein the situation images are updated at regular intervals of a few seconds, and the situation images are archived.

Description

[0001] Procedure for making an emergency call in a vehicle

[0002] The invention relates to a method for making an emergency call in a vehicle according to the preamble of claim 1.

[0003] Making an emergency call is an important part of the rescue chain. The so-called 5 W rule is known as follows:

[0004] Where is the event?

[0005] Who is calling?

[0006] What happened?

[0007] How many are affected?

[0008] Waiting for inquiries!

[0009] However, it's often difficult for those affected to follow this rule. In particular, callers often have trouble locating the scene of the accident or emergency. Furthermore, in many cases, a precise description of the emergency is missing.

[0010] It is also known that smartphones can be located when an emergency call is triggered. Emergency call apps for people with speech and hearing impairments are also known.

[0011] US 2020 / 0029194 A1 describes a headlight assembly for use in a vehicle and for reporting emergency conditions to a dispatcher, the headlight assembly comprising a housing forming a cavity, a processor mounted in the cavity, a wireless transceiver carried by the housing and connected to the processor, at least one first sensor device for detecting at least one first condition while the vehicle is in operation, the first sensor device being in communication with the processor, the processor being programmed to receive data from the at least one first sensor device, analyze the received data to assess the probability that an emergency condition exists, and upon determining that the probability of an emergency condition is greater than a first threshold,automatically initiate wireless emergency reporting communication with an emergency control center.

[0012] The invention is based on the object of providing a novel method for making an emergency call in a vehicle.

[0013] The object is achieved according to the invention by a method for making an emergency call in a vehicle having the features of claim 1.

[0014] - A method for making an emergency call in a vehicle is proposed, wherein when an emergency number is dialled using a mobile terminal, an interface appears on the mobile terminal or on a secondary display of the vehicle, the following features being transmitted: o caller identity, o emergency location, wherein coordinates of the emergency location are determined using a global satellite navigation system of the vehicle or the mobile terminal and adopted in the mask, o situation images of an area outside the vehicle, which are created with the aid of cameras provided on the vehicle to describe the situation, wherein the interface is configured in such a way that the connection to the emergency number can be ended not by a single actuation, but only by at least two confirmations.

[0015] According to the invention, an input mask appears on the surface, which requests the entry or correction of the following features:

[0016] - caller identity,

[0017] - Emergency location (e.g. via “what3words”),

[0018] - Number of persons affected,

[0019] - number of occupants of the vehicle, and - description of the situation, whereby the caller's identity is taken from a tachograph from a driver card or from a currently selected driver profile or from personal data available on the mobile device, whereby a cartographic description of the emergency location is supplemented on the basis of data from a digital map, whereby the number of occupants of the vehicle is determined by seat recognition and / or seat belt buckle recognition and by an interior camera, whereby the situation images are updated at regular intervals of a few seconds, whereby the situation images are archived.

[0020] The solution according to the invention allows for the precise and rapid placing of an emergency call, whereby the rescue control center receives a better picture of the situation through photographic image material.

[0021] The vehicle can be configured, for example, as a commercial vehicle, bus or passenger car.

[0022] Embodiments of the invention are explained in more detail below with reference to a drawing.

[0023] It shows:

[0024] Fig. 1 is a schematic view of a method for making an emergency call.

[0025] The single figure is a schematic view of a method for making an emergency call in a vehicle.

[0026] The vehicle is equipped with a mobile device, such as a smartphone, and / or a secondary display on which an interface 1 appears when dialing an emergency call (e.g., 112 or 911) to a rescue control center. This interface 1 has a mask that assists the caller in describing the emergency situation. The mask prompts the caller to enter the following information:

[0027] - Caller identity: Who is calling? The caller identity information can be retrieved from a tachograph 2 driver card, a currently selected driver profile, or personal data available on the mobile device (e.g., Apple ID or Google User) and pre-entered into the form. Alternatively, the caller can enter or edit the name manually.

[0028] - Accident or emergency location: Where is the emergency location? The coordinates of the vehicle and thus the emergency location are determined, for example, using a global navigation satellite system (GNSS) 3 of the vehicle or mobile device and are also added to the form. In addition to the coordinates, a cartographic description (e.g., Autobahn A8, exit xy, northbound, kilometer 53) can be added based on data from a digital map 4. Alternatively, the caller can enter or edit this information manually.

[0029] - Number of persons affected: An input option is provided for this feature on the mask.

[0030] - Number of vehicle occupants: The number of people in the vehicle from which the emergency call is made can be determined by seat recognition and / or seat belt buckle detection and / or an interior camera. Alternatively, the caller can enter or edit this information manually.

[0031] - Situation description: Situation images are created and transmitted from an area outside the vehicle using at least one camera 5.1, 5.2, 5.3 (e.g., a multifunction camera - MPC, MCS, SVS). The situation can be updated at regular intervals of a few seconds. Archiving of the image data for later investigation by the police can also be provided.

[0032] The interface 1 can be configured in such a way that it is not possible to terminate the connection to the rescue coordination centre with a single actuation, but that at least two confirmations are required to terminate the connection.
