Description

1 PROCEDURE AND SENSOR FOR INFORMATION TRANSFER TECHNICAL FIELD The invention relates to methods and sensors in vehicles. More particularly, the invention provides a mechanism for transmitting information associated with an object detected by a first sensor in a first vehicle, to a second sensor in a second vehicle.

BACKGROUND A vehicle sometimes includes a driver assistance system comprising sensors such as radar, cameras and similar types of sensors, which identify objects around the vehicle, such as, for example, lanes, signs, pedestrians, game and other surrounding vehicles.

In this context, vehicles refer to, for example, lorries, lorries, car, passenger car, emergency vehicle, craft, bus, motorcycle, fire truck, annfibie craft, boat, aircraft, helicopter or other similar motorized or unmanned means of transport, adapted for geographical movement by land, sea or air.

In many situations, however, the sensor in a vehicle is obscured by a rear-facing vehicle, especially since the front vehicle is a heavy vehicle such as a truck, a bus, or similar large and / or bulky vehicle.

In a case where, for example, a passenger gets out of a bus, and goes out in front of the bus to cross the road, it may be black for a vehicle behind and / or overtaking to perceive the pedestrian in front of the front vehicle, also in the rear the vehicle has a sensor, because the front vehicle obscures the view of both the sensor and the driver of the vehicle. If the vehicle behind starts to re-churn the stationary bus in this situation, a serious accident can follow, unless the passenger perceives and realizes the danger in his actions. 2 Another example of a possible accident may be when a wild animal such as a wild boar, algae, radish or the like suddenly crosses the road in front of a vehicle in front. The sensor in the own vehicle is then obscured by the vehicle in front, so the driver in the vehicle behind may be surprised by the vehicle in front. the vehicle's sudden and slow braking and / or other wildlife following the first game across the road.

It can be stated that much remains to be done to improve sensors and driver assistance systems in vehicles.

SUMMARY It is therefore an object of this invention to improve a vehicle driver's perception of emerging objects in the lane, in order to solve at least some of the above problems and to achieve a vehicle improvement.

According to a first aspect of the invention, this grinding is achieved by a process those in a first sensor in a first vehicle for transmitting information associated with an object detected by the first sensor, to a second sensor in a second vehicle. The method involves detecting the object. Further, the method comprises transmitting wireless information associated with the detected object, for receiving the second sensor in the second vehicle.

According to a second aspect of the invention, this targeting is achieved by a sensor in a first vehicle, arranged to detect an object and transmit information associated with the detected object to a second sensor in a second vehicle. The sensor comprises a detector arranged to detect the object. Furthermore, the sensor comprises a transmitter arranged to transmit wireless information associated with the detection. the object, for receiving the second sensor in the second vehicle.

According to a third aspect of the invention, this targeting is achieved by a method in a second sensor in a second vehicle, for taking any information associated with an object detected by a first sensor in a first vehicle. This procedure involves receiving wireless information associated with the object Than the first 3 the sensor in the first vehicle. The method also includes initiating an accident-avoiding action, in order to avoid an accident with the object.

According to a fourth aspect of the invention, this grinding is achieved by a sensor in a second vehicle. This sensor is arranged to receive associated information with an object detected by a first sensor in a first vehicle. The sensor comprises a detector arranged to receive wireless information associated with the object, tan the first sensor in the first vehicle. Furthermore, the sensor comprises a processor circuit arranged to initiate an accident-avoiding action, in order to avoid an accident with the object.

By transmitting information regarding an object detected in the vicinity of a first vehicle, by a sensor in this first vehicle, to a second sensor in a second vehicle which is located on the same section of road as the first vehicle, -Waren in the second vehicle can be warned of a hazard that has been detected by the first sensor in the first vehicle. This allows the driver of the other vehicle detect an object such as a pedestrian or wild boar that is on the roof lane near your own vehicle but hidden by the other vehicle, for example, even though the driver himself or the sensor in this other vehicle cannot see / detect this object when it is dolt. This increases traffic safety for the vehicles as well as for surrounding road users. By transmitting information wirelessly over a limited such a rack width, for example directly between the vehicles' sensors via a light-borne interface, avoids warning a vehicle driver who is not affected by the situation that has arisen. In some embodiments, existing sensors can be used on the vehicles, for example radar, lidar and / or camera, such as, for example, a Time of flight scanner, which in themselves can be used for other purposes, for example distance to front vehicle in order to warn the driver if the distance is too short, and / or to adapt the vehicle's cruise control to the speed of the front vehicle, then an additional functionality can be obtained by the invention, without the number of components in the vehicle, and thus the cost of materials and manufacturing . This achieves an improvement of the vehicles.

Other advantages and additional features will become apparent from the following detailed description of the invention. 4 LIST OF FIGURES The invention will now be described in further detail with reference to the accompanying figures, which illustrate various embodiments of the invention: Figure 1 Illustrates an embodiment of two vehicles with sensors according to an embodiment. ring shape, in a side view.

DETAILED DESCRIPTION OF THE INVENTION The invention is defined as methods and sensors for transmitting information associated with an object detected by a first sensor to a second sensor in a second vehicle, which can be realized in any of the embodiments described below. However, this invention may be practiced in many different forms and should not be construed as limited by the embodiments described herein, which are intended to illustrate and illustrate various aspects of the invention.

Additional aspects and features of the invention may become apparent from the following detailed description when considered in conjunction with the accompanying figures. The figures are, however, to be considered only as examples of different embodiments of the invention and should not be construed as limiting the invention, which is limited only by the appended claims. Furthermore, the figures are not necessarily so Are drawn to scale and are, unless otherwise specifically stated, intended to conceptually illustrate aspects of the invention.

Figure 1A shows a carriage section 100 on which a front vehicle 101 and a rear vehicle 102 are driven in a tank direction of travel 105. The vehicles 101, 102 may be in motion in the direction of travel 105, or be stationary, prepared for a planned movement in The direction of travel 105. It may also be the case that the front vehicle 101 is stationary and the rear vehicle 102 undergoes a detour in the direction of travel 105.

The front vehicle 101 has a sensor 111, which is arranged to detect surrounding objects 120, for example game, pedestrians, other vehicles, obstacles or the like. It is irrelevant to the invention whether the object 120 is in motion or stationary.

The rear vehicle 102 also has a sensor 112. These sensors 111, 112 may be located at any location on the respective vehicle 101, 102 but preferably with a location as high up or on the roof as possible on the respective vehicle 101, 102 for to obtain as long a field of vision as possible, and obscure as little as possible as possible by other objects, such as other vehicles. The sensors 111, 112 can also be located inside the wheelhouse of the respective vehicles 101, 102, for example high up near the ceiling. They are there protected from external damage such as contamination of dust and slush, as well as from damage and in some cases stolen. 6 This first sensor 111 and / or second sensor 112 can be constituted by, for example, a camera, a 3D camera, a Time of Flight camera (ToF camera), a stereo camera, a light field camera, a radar feeder, a laser feeder, a lidar, a spacers based on ultrasonic waves or similar sensor.

A lidar is an optical food instrument that measures the properties of reflected light to find the distance (and / or other properties) of a remote object 120. The technology is very much about radar, (Radio Detection and Ranging), but instead of radio waves light is used . Typically, the distance to the object 120 is measured by feeding the time delay between a transmitted laser pulse and the recorded one. 10 reflexes.

A ToF camera is a camera system that takes a sequence of pictures and measures a distance to the object 120 based on the known light speed, by feeding the time input for a light signal between the sensor 111, 112 and the object 120.

Furthermore, the first sensor 111 and the second sensor 112 may be the same type of sensor or different types of sensors according to different embodiments. In some embodiments, more than one respective sensor 111, 112 may be mounted on the first vehicle 101 and / or the second vehicle 102. An advantage of having more sensors 111, 112 is that more reliable distance assessment can be made and that a large area can be thanked with these sensors.

Neither the driver of the rear vehicle 102 nor the sensor 112 can in this scenario in Figure 1A see the object 120 in front of the front vehicle 101, as this is obscured by the front vehicle 101. On the other hand, the object 120 is detected by the sensor 111 in the front vehicle 101. This sensor 111 in the front vehicle 101 sends information regarding the detected object 120 in front of the own vehicle, to be received by the sensor 112 in the second vehicle 102. Thereby, it is possible for the goods in the rear vehicle 102 to receive a warning about an object 120 appearing in front of the front vehicle 101. This allows the driver in the rear vehicle 102, as well as the driver in the rear vehicle 102. from the front of the vehicle 101 is warned by an audible signal, an audio message, a light signal, a signal displayed on a monitor, a tactile signal 7 warning signal which transmits vibration to the driver via a vibrator in the driver 's seat, steering wheel and / or gear lever, or similar warning signal in certain embodiments.

In other embodiments, this information about a hidden object 120 in front of a vehicle in front 101 may be used to initiate an accident avoidance action, such as making deceleration impossible, slowing down, slowing down, and / or evasive maneuvering.

The transfer of information from the first sensor 111 in the front vehicle 101 to the second sensor 112 in the rear vehicle 102 can be done via a wireless interface, based on, for example, the Global System for Mobile Communications. 10 (GSM), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Code Division Access (CDMA), (CDMA 2000), Time Division Synchronous CDMA (TD-SCDMA), Long Term Evolution (LIE ), LIE- Advanced; Wireless Fidelity (Wi-Fi), defined by the Institute of Electrical and Electronics Engineers (IEEE) standards 802.11 a, b, g and / or n, Internet Protocols COI (IP), Bluetooth and / or Near Field Communication, (NFC).

An advantage of transmitting information wirelessly via radio waves may be that you then have a range that is sufficient to warn a large number of other vehicles 102. If, for example, a game has come inside a game fence on a motorway, then this is a traffic hazard not only for that own vehicle 101 and the vehicle behind 102 but also for other vehicles that operate the relevant section of the road in any direction.

In some embodiments, the wireless interface is a light-borne interface where information can be transmitted between the first sensor 111 and the second sensor 112 by modulating the emitted light.

Although the second sensor 112 cannot see the object 120, it can detect light reflections emitted from the first sensor 111, and these light waves can be used to transmit information to the second sensor 112. For example, this information may include only a bit in some embodiments. , that is to say "object detected" and "no object detected" respectively. 8 This amount of information may seem small, but the spirit may be sufficient to trigger a yarning or atgard. A comparison can be made when crossing in the dark on a road with oncoming traffic. If you see light bulbs Than a moving vehicle behind a rising hill, you do not know what kind of vehicle you are driving, how fast this ktir etc., but it may spirit be inappropriate to pabOrja detour.

In other embodiments, additional information may be transmitted, such as the type of object, where in relation to the vehicle 101 the object 120 is detected, the size of the object and other similar information. As a result, the information receiving second sensor 112 can be communicated with additional information, which can enable one Assessment or evaluation of how relevant or dangerous the detected object 120 is to the traffic safety of the own vehicle 102.

The emitted light from the respective sensors 111, 112 may be within the visible spectrum (about 390 and 770 nanometers) but in different embodiments it may also, or alternatively comprise infrared light (IR), which has a wavelength exceeding 770 nanometers, and / or ultraviolet straining (UV) with a shorter wavelength of 390 nanometers.

The light modulation can in certain embodiments take place by modulating frequency, wavelength, amplitude and / or time in different embodiments.

To take a simple example, a constant outflow of infrared light from the first the sensor 111 can only display the information "no object detected" while a bright pulsating orange light can only display the information "object detected". This makes it possible for the sensor 102 in the rear vehicle 102 to interpret this information. In some embodiments, it may even be possible for the driver of the rear vehicle 102 to immediately notice the object 120 in front of the front vehicle 101, even if it own vehicle 102 lacks a sensor, or its own sensor 112 is defective or misaligned, by being warned directly by the light signals from the first sensor 111 in the first vehicle 101.

An advantage of transmitting light-borne information is that it can be sent directly by the first sensor 111 and received directly by the second sensor 112, without 9 behOya is processed or transformed into radio waves. As a result, information can be transmitted faster than if transmission takes place via a radio interface, as there is no need for fast connection time. The limited range yid Transmission of light-borne information has the advantage that information that is irrelevant due to the fact that it the emerging object 120 is simply far Than Than its own vehicle 102, perhaps on another road, or in another direction horizontally or vertically, is simply filtered out as the sensor 112 in the underlying vehicle 102 then cannot receive this information. Light-borne information thus has high credibility for the receiving party. In some embodiments, the first sensor 111 may send information related to the detected object to all vehicles; to all vehicles arranged to receive this information; to all vehicles arranged to receive this information within a certain aystand, to all vehicles connected to a service which allows the use of such information, according to different embodiments.

Figure 1B shows the same wagon section 100 with the same vehicle 101, 102 and the same traffic situation as shown in figure 1A but seen in a bird's eye view.

Figure 2A also shows the same road section 100 with the same vehicle 101, 102 and the same traffic situation as shown in Figure 1A and Figure 1B but seen from a perspective from the driver's seat inside the vehicle behind 102. The sensor 112 in this vehicle behind 102 receives information Than the first sensor 111 in the front vehicle 101.

In this example, the vehicle 102 comprises a side module 1 with a display 140, which are arranged to communicate with the sensor 112 and convey a received warning of the possible traffic danger arising to the driver of the vehicle, e.g. by sound signal, light signal, or by blasting the resulting situation and / or the object 120 on the screen 140, to now name some examples of such a yarning, according to various embodiments.

Figure 2B shows an example of how such an ash damage could be done, so that the driver can quickly understand the situation that has arisen and give him the opportunity to take appropriate action. In certain other embodiments, instead of, or in addition to, a vehicle given to the driver, an action may be taken for the purpose of avoiding, or at least reducing, the consequences of an accident such as preventing a vehicle from moving, braking the vehicle 102, starting to evade, exiting game deterrent late / scent or similar.

Figure 3 illustrates an exemplary embodiment of a method 300 in a first sensor 111 in a first vehicle 101. The method 300 is arranged to transmit information associated with an object 120, detected by the first sensor 111, to a second sensor 112 in a second vehicle 102. This information is transmitted wirelessly according to certain embodiments. Such wireless information may include light-borne information, which may be emitted by modulating the emitted light Than sensor 111. Such modulation may be made in phase, amplitude and / or time on the emitted light waves.

According to certain embodiments, the wireless information may be transmitted via radio waves between the vehicles 101, 102; for example based on any of the following technologies: GSM, EDGE, UMTS, CDMA, CDMA 2000, TD-SCDMA, LTE, LTE Advanced; Wi-Fl, IP, Bluetooth and / or NFC according to different embodiments.

In order to be able to transmit information correctly, the method 300 may include a number of steps 301-304. However, it is observed that some of the steps described 301-304 can be performed in a slightly different chronological order than what the number order suggests and that some of them can be performed in parallel with each other, according to different embodiments. Furthermore, certain steps are performed only in certain embodiments, such as steps 302 and 303. The method 300 includes the following steps: Step 301 The object 120 is detected by the first sensor 111. Step 302 This process step may be performed in some, but not necessarily all, embodiments of the process 300. 11 The detected 301 object 120 is identified as a possible traffic hazard.

Such detection can be made by determining the position of the object in relation to the vehicle 101, for example if it is located on the track 100 or outside it; if the object 120 is moving towards the vehicle 101 or moving away from it; the size of the object, for example by comparison with a spruce sword; or by identifying the type or category of objects 120. These different types of objects can be categorized as dangerous or harmless from a road safety point of view.

In certain embodiments, objects 120 may, for example, be in the form of pedestrians and game located on the carriageway 100 within a distance of, for example, 50 meters 10 is classified as a possible traffic hazard. In some embodiments, objects 120 that are outside the lane 100 but move toward the lane 100 can be identified as a potential traffic hazard. In some embodiments, objects 120 that are on the roadway and have a size that exceeds a certain threshold value can be identified as a possible traffic hazard.

These are just a few non-limiting examples of different possibilities for configuring the identification of a possible traffic hazard in order to activate a vehicle in one's own vehicle 101 and / or the other vehicle 102 in a situation which does not constitute a traffic hazard, for example that the sensor 111 has detected a permanently mounted traffic sign next to the lane 100.

Step 303 This process step may be performed in some, but not necessarily all, embodiments of the process 300.

The second sensor 112 in the second vehicle 102, which is arranged to receive a sanding of wireless information, is detected. Furthermore, a transmission of such wireless information only when the second sensor 112 in the second vehicle 102 is detected according to certain embodiments.

This detection can be made by the first sensor 111 in the front vehicle 101 detecting emitted light from the second sensor 112 in the rear vehicle 102. 12 Thereby it can be stated that also the second sensor 112 is sufficiently close to be able to receive information from the first sensor 112, for instance through light-borne information sent out by the first sensor 112.

This makes it possible to avoid sending information associated with the detected object 301 120, as this is not meaningful, for example, because there is no other vehicle 102 in the vicinity. This saves processor capacity and energy in the sensor 101.

Step 304 Tracilo's information associated with the detected 301 object 120 is transmitted, to receive the second sensor 112 in the second vehicle 102.

The transmitted information may in various embodiments include: the presence and absence of an object 120, type of detected object 120, position of this object 120 from the first sensor 111, size of the object 120, geographical position, hazard level.

According to some embodiments, wireless information is transmitted only when the detected 301 object 120 is identified 302 as a potential traffic hazard. Furthermore, unnecessary warnings can be avoided to be sent to unsuspecting vehicles 102.

According to some embodiments, wireless information is transmitted only when another sensor 112 is arranged to receive wireless information, such as light-borne data. this information has been detected 303. This avoids wasting time and processor capacity on sending alerts that no other sensor spirit can receive.

Figure 4 shows an embodiment of a sensor 111 in a first vehicle 101. This sensor 111 is configured to perform at least some of the previously described the method steps 301-304, included in the description of the method 300 for detecting an object 120 and transmitting information associated with the detected object 120 to a second sensor 112 in a second vehicle 102. 13 The sensor 111 may be, for example,: a camera, a 3D camera, a Time of Flight camera, a stereo camera, a light field camera, a radar feeder, a laser feeder, a lidar and / or a distance monitor based on ultrasonic waves.

Furthermore, the sensor 111 may comprise a processor circuit 4 arranged to identify the detected object 120 as a possible traffic hazard. 14 The processor circuit 420 may be, for example, one or more Central Processing Units (CPUs), microprocessors or other logic designed to interpret and execute instructions and / or to read and write data. The processor circuit 420 may handle data for inflow, outflow or data processing of data including buffering of data, control functions and the like.

The sensor 111 may further comprise according to certain embodiments, or be connected to a memory unit 4 which in certain embodiments may be constituted by a storage medium for data.

Thereby, the method 300 according to at least some of the steps 301-304 for transmitting information associated with an object 120 detected by a first sensor 111 in a first vehicle 101, to a second sensor 112 in a second vehicle 102 may be implemented by one or more processor circuits 420 in the sensor 111 together with computer program code to perform flags, some, some or all of the steps 301304 described above. Thereby, a computer program including instructions for performing steps 301-304 as the program is loaded into the processor circuit 420.

This computer program described above in the vehicle 101 is in certain embodiments arranged to be installed in the memory unit 425 in the sensor 111, for example over a tad-lost interface.

Figure illustrates an exemplary embodiment of a method 500 in a second sensor 112 in a second vehicle 102, for receiving information associated with an object 120 detected by a first sensor 111 in a first vehicle 101.

This information is received wirelessly according to certain embodiments. Sadan wireless information may include light-borne information, which may be emitted by modulating the emitted light from the sensor 111 and interpreted by corresponding demodulation of the second sensor 112.
