Definitions
- the invention relates to a method for transmitting information from a vehicle driving ahead to a rear vehicle located immediately behind the vehicle driving ahead about another road user in front of the vehicle driving ahead.
- EP 3 399 330 A1 relates to an object detection system for an automated vehicle, comprising: an object detector that detects detectable objects in the vicinity of the own vehicle; a receiver that receives an indication of an object presence from other transmitters in the vicinity of the own vehicle; and a controller in communication with the object detector and the receiver, wherein the controller is configured to operate the own vehicle to avoid a collision with a hidden object if the hidden object is not detected by the object detector and the presence of the object is indicated by at least two instances of the other transmitters.
- US 2018101736 A1 describes methods for providing a visual security image for a vehicle, an electronic device and a computer-readable recording medium therefor.
- DE 102012018556 A1 relates to an assistance system for enabling an extended foresight for following road users with a sensor device with which images of a vehicle environment substantially in front of a first vehicle can be recorded in chronological sequence, characterized in that the sensor device comprises a stereo sensor device for recording three-dimensional images, and images recorded by the sensor device Images of the vehicle surroundings substantially in front of the first vehicle can be displayed in a three-dimensional manner for the eyes of a driver of at least one second vehicle following the first vehicle, in that the first vehicle comprises a display device in the rear area for a three-dimensional display of the images detected by the sensor device.
- DE 102004049870 A1 describes a method and a device for improving the visibility of drivers of motor vehicles which are provided with receiving devices and display devices for image data, wherein the images from a respective other vehicle driving ahead, which is equipped with at least one video camera aligned in the direction of travel and a transmitting device for the image data generated by the at least one video camera, are received and displayed by the receiving device and display device.
- Such a concealment problem as explained at the beginning can occur in particular when one's own vehicle, such as a passenger car, is following behind a much larger vehicle such as a truck, but also, for example, when a small car is following behind an off-road vehicle designed for cities or a small van. Even if a sufficiently large distance is maintained from the vehicle in front, other road users ahead can be concealed.
- city off-road vehicles are becoming increasingly popular with consumers, and on the other hand, there is a tendency to use small and aerodynamically optimized electric vehicles that are rather narrow and/or flat. Such a situation requires increased attention from the driver of the following vehicle.
- the object of the invention is to reduce a potential danger for a rear vehicle when another road user is or can be obscured by a vehicle driving ahead of the rear vehicle.
- a first aspect of the invention relates to a method for transmitting information from a vehicle driving ahead to a rear vehicle located immediately behind the vehicle driving ahead via another road user in front of the vehicle driving ahead, comprising the steps:
- the vehicle in front and the rear vehicle immediately behind the vehicle in front thus form a pair of vehicles, with the vehicle in front having the potential to obscure other road users in front of the vehicle in front for the vehicle in rear. This is particularly the case if the vehicle in front is larger and/or higher than the vehicle in rear.
- a process can be initiated by the vehicle in rear to obtain information from a sensor unit in the vehicle in front, which records a forward environment including other road users in front of the vehicle in front.
- a so-called "handshake" takes place in a first step in order to connect the vehicle in front and the vehicle behind in terms of information technology.
- the vehicle behind therefore first records and evaluates the registration number of the vehicle in front and uses a central database to evaluate whether the vehicle in front is under his registration number participates in a corresponding program and has registered for it in advance. This is an important prerequisite to prevent the sensor data of a vehicle (in this case the one driving ahead) from being accessed by arbitrary units.
- the absolute positions, in particular positions determined using satellites, of the vehicle in front and the vehicle behind are checked to see whether they are very close to each other in order to ensure that only vehicles that are actually nearby (at the rear) are able to make such a request and receive the sensor information from the vehicle in front.
- Two-factor authentication is therefore carried out in order to complete the "pairing" of the vehicle in front and the vehicle behind.
- the sensor information is preferably displayed in the vehicle behind (possibly only minimally processed), but can also be output with additional information.
- the symbolism of activated brake lights is generated automatically from the sensor information of the vehicle in front. If, for example, the road user in front performs a dangerous maneuver, brakes (particularly heavily), or something similar, a separate warning can be issued to the vehicle behind.
- a possible application of such a method is also in the field of electronic drawbars, also called “platooning", where the overall efficiency of several vehicles is improved by allowing them to drive one behind the other at a very short distance, while special mechanisms are provided to ensure safety, for example to prevent a series of rear-end collisions in the event of emergency braking by the vehicle at the front.
- the transmission of the Sensor information from the vehicle in front to the vehicle behind via wireless transmission using the 5G standard is also possible, but can lead to stability problems during transmission or be inappropriate due to excessive time delay.
- the transmitted sensor information is visually displayed on a display unit, in particular a screen or a head-up display, on the rear vehicle.
- the display is as simple as possible so as not to unnecessarily distract the driver of the rear vehicle.
- Intuitive displays can be made in which, for example, the other road user is indicated in augmented reality, as if the vehicle in front were transparent.
- the sensor information about the other road user is displayed superimposed on an image of the vehicle in front.
- cross-sectional sizes of the vehicle in front and of the other road user are visualized in real proportion.
- cross-sectional sizes of the preceding vehicle and of the other road user are displayed depending on a distance of the preceding vehicle from the other road user.
- information is output to the rear vehicle as to whether there is another road user in front of the vehicle in front.
- the central database receives the request to obtain the absolute position of the vehicle in front and, upon pre-registration of the vehicle in front, checks the absolute position of the vehicle in front and the vehicle behind to see whether they are in the specified common area relative to each other and, if the answer is positive, issues a Permission for the vehicle in front to transmit the sensor information to the vehicle behind.
- the continuous transmission of sensor information from the vehicle in front to the vehicle behind is stopped when the vehicle behind leaves the lane of the vehicle in front and/or another vehicle positions itself between the vehicle in front and the vehicle behind and/or when a minimum distance between the vehicle in front and the vehicle behind is exceeded, wherein the minimum distance is selected in particular as a function of speed.
- only sensor information is transmitted from the vehicle in front to the vehicle behind, but not information about the current speed or the driving behavior of the other road user.
- compressed and/or preprocessed sensor information is transmitted from the vehicle in front to the vehicle behind.
- Fig. 1 A method for transmitting information from a preceding vehicle to a rear vehicle via another road user according to an embodiment of the invention.
- Fig. 2 A traffic situation in which the method according to Fig. 1 can be used.
- Fig. 3 A traffic situation in which the method according to Fig. 1 is terminated.
- Fig. 4 A visualization applied in the method of Fig. 1.
- Fig. 1 shows a method for transmitting information from a vehicle 1 driving ahead to a rear vehicle 3 located directly behind the vehicle 1 driving ahead about another road user 5 in front of the vehicle 1 driving ahead.
- Fig. 2 can also be used, which shows a corresponding traffic situation, wherein in particular the vehicle 1 driving ahead is a van and has dimensions that significantly exceed the rear vehicle 3 driving behind it. This can result in the case that a driver of the rear vehicle 3 does not see another road user 5 who is in front of the vehicle 1 driving ahead, and, for example, if the other road user 5 brakes heavily, the vehicle 1 driving ahead will perform an emergency stop.
- the rear vehicle 3 determines S1 a registration number of the vehicle 1 in front in order to carry out a comparison S2 of the determined registration number of the vehicle 1 in front with a central database 7 for advance registration.
- the rear vehicle 3 or the database 7 itself sends S3 a request to the vehicle 1 driving ahead to receive a WGS-84 position of the vehicle 1 driving ahead. It is then checked S4 whether the WGS-84 position of the vehicle 1 driving ahead and a WGS-84 position of the vehicle 3 driving behind are within a predetermined common area, i.e. are in close proximity to one another. To do this, the common area is moved along with the vehicle 1 driving ahead.
- the vehicle 3 driving behind is within the area around the vehicle 1 driving ahead, there is then a continuous transmission S5 of sensor information from the vehicle 1 driving ahead to the vehicle 3 driving behind, whereby the sensor information contains data about the environment in front of the vehicle 1 in front, including another road user 5 in this vicinity.
- This sensor information includes, in particular, camera data from the vehicle 1 in front, which captures an environment in front of the vehicle 1 in front and thus the other road user 5.
- Fig. 3 shows a situation in which a gap has arisen between the rear vehicle 3 and the vehicle 1 in front, and another vehicle is about to pull into this gap.
- the continuous transmission of sensor information from the vehicle in front to the rear vehicle is interrupted when the other vehicle pulls into the gap, or when the distance between the vehicle 1 in front and the vehicle 3 in rear has already become too large.
- Fig. 4 shows a possible display of the other road user 5 relative to the vehicle 1 in front.
- the vehicle 1 in front is shown transparently and the other road user 5 as if it were shining through the other road user 1. This makes it easy for the driver of the rear vehicle 3 to see if a possibly hidden other road user 5 is in front of the vehicle 1 in front. This is shown on a screen or on a head-up display of the rear vehicle 3.
