Description

[0001] The present invention relates to a method for displaying information about a vehicle's surroundings and a device that uses the method, as well as a vehicle with the device. The present invention particularly relates to a method for displaying information about the vehicle's surroundings in order to provide assistance to the driver of the vehicle when parking or maneuvering the vehicle.

[0002] Vehicles, such as cars or trucks, are often difficult to see out of due to aerodynamic or design reasons, making it hard for the driver to judge or assess the vehicle's dimensions. This makes parking or maneuvering particularly challenging in confined spaces, such as parking lots or parking garages. Therefore, these vehicles are frequently equipped with parking distance warning systems, also known as Park Distance Control (PDC).

[0003] DE 10 2009 024 062 A1 relates to a device and a method for displaying objects in a vehicle's environment, comprising a sensor arrangement for detecting objects in the vehicle's environment and determining their position relative to the vehicle. The sensor arrangement's detection range covers only a portion of the vehicle's environment. To improve driver assistance during parking maneuvers, the processing unit is configured to identify the area of ​​the vehicle's environment for which no object information is yet available, as it has not been covered by the sensor arrangement's detection range. The display device is configured to indicate the extent of this area.

[0004] German patent DE 10 2008 001 648 A1 teaches a driver assistance system for moving a motor vehicle, in particular for avoiding collisions, using at least one first sensor system which provides initial obstacle information to the driver of the motor vehicle in a first detection range as long as an obstacle is located in the first detection range, and at least one second sensor system which provides further obstacle information in a second detection range positioned at an angle greater than 0° to the first detection range, even when the obstacle is no longer located in the second detection range. The system provides for the merging of the first and second obstacle information in such a way that detection errors of the sensor systems are corrected and updated obstacle information is provided.The invention further comprises a driver assistance device, in particular for carrying out the driver assistance procedure according to the preceding descriptions.

[0005] German patent DE 43 33 112 A1 describes a method and a device for maneuvering a vehicle out of a parking space when neither the size nor the distance to obstacles is known. Sensors mounted on the vehicle detect both the distance and the steering angle of the moving vehicle and continuously determine the distance to the surrounding obstacles. Based on this data, a current local environment map is created in a computer module. The detected obstacles are connected as barriers using a polygonal line. From this data, an environment model is generated, which is used to determine a driving strategy for maneuvering the vehicle out of the parking space. Corresponding direction indicators guide the driver of the vehicle towards the correct direction.

[0006] For example, DE 10 2008 036 009 A1 relates to a method for collision protection of a motor vehicle. The vehicle has environmental sensors for detecting objects in its vicinity. In this method, sensor information from the environmental sensors is acquired, and an environmental map is created from this information. The environmental map is updated with the sensor information from each new acquisition cycle. Since the current sensor information is measured relative to a vehicle-fixed coordinate system, this information must be transformed into the spatially fixed coordinate system of the environmental map in order to update it. Knowing the vehicle speed and steering angle, this transformation can be performed taking the vehicle's movement into account.By updating the environmental map with each acquisition cycle, taking into account the vehicle's own movement, the environmental map contains not only objects from the current sensor measurement but also from a previous one. Thus, the environmental map can contain information about objects in the 360° surroundings of the vehicle, and a collision probability can also be determined for objects not currently detected by the environmental sensors but present in the environmental map, since the environmental map essentially has a memory.

[0007] Thus, for example, objects in the vehicle's side area can be detected using ultrasonic sensors for side protection and tracked using the vehicle's own movement, the so-called odometry data. A warning (visual or audible) typically covers the entire side area. To build the object tracking map, this area must first be scanned. Immediately after switching on the ignition, for example when backing out of a perpendicular parking space, and after traveling a short distance insufficient to cover the entire side area, no display for the entire side area can be generated. This means that driver assistance is lost, and a collision in the side area can therefore occur.

[0008] The object of the present invention is therefore to provide an improved method for displaying the vehicle's surroundings, in particular the side area of ​​the vehicle, especially when complete information for the entire side area is not yet available.

[0009] This problem is solved according to the present invention by a method for displaying information about the environment of a vehicle according to claim 1, a device for a vehicle according to claim 8, and a vehicle according to claim 10. The dependent claims define preferred and advantageous embodiments of the invention.

[0010] According to the present invention, a method for displaying information about a vehicle's environment is provided. In this method, environmental information is determined for an area along a longitudinal side of the vehicle. This environmental information indicates whether or not an object is present in the area along the vehicle's longitudinal side. The environmental information is determined based on sensor information from a sensor on the vehicle and motion information from the vehicle's movement. This is achieved by scanning the area with the sensor as the vehicle moves; that is, the sensor acquires sensor information while the vehicle is in motion. The sensor can, for example, be located at the front end of the vehicle and monitor an area transverse to the vehicle. The front end is, for example, an area laterally on the vehicle in front of the front wheel arch.When the vehicle is moving forward, this sensor can scan environmental information along the vehicle's longitudinal side. Additionally, a sensor can be mounted at the rear of the vehicle to capture environmental information perpendicular to the vehicle. The rear end is, for example, an area on the side of the vehicle behind the rear wheel arch. This sensor can then be used to scan the area along the vehicle's longitudinal side when the vehicle is reversing. If the environmental information along the longitudinal side is incompletely scanned, i.e.,If the sensor's detection range, in combination with the vehicle's movement, could not scan the entire area along the vehicle's side—for example, because the vehicle only traveled a portion of the length after the entire scanning system was activated—the information about the environment for this partially scanned area along the side is displayed on a vehicle display unit in an area that does not correspond to the vehicle's side. For example, the information about the environment for this partially scanned area along the side might be displayed in a front outer area or a rear outer area; that is, the information is displayed for an area located laterally in front of or laterally behind the vehicle.These areas to the side in front of or behind the vehicle can, for example, be the same areas in which corresponding information from sensors in a front or rear bumper is displayed, each scanning a corresponding area in front of or behind the vehicle.

[0011] For example, when the vehicle's ignition is switched on to reverse out of a perpendicular parking space and a short distance of, say, half the vehicle length is traveled, only incomplete information about the surroundings along the vehicle's side is available. This incomplete information cannot yet be displayed to the driver as longitudinal side surroundings information, even though partial information is already available. According to the present invention, this partial information is therefore displayed as surroundings information for the corresponding front or rear outer area of ​​the vehicle on the vehicle's display unit. In particular, this surroundings information can be displayed as a warning when the vehicle moves in such a way that it approaches an object in the partially scanned area along the vehicle's side.This will cause the driver to intuitively steer away from the object, thus preventing a collision.

[0012] According to one embodiment, the environmental information for the area along the longitudinal side between a front end of the vehicle and a center point or B-pillar is displayed on the vehicle's display unit as environmental information for the front outer area on the corresponding longitudinal side if the environmental information along the longitudinal side was incompletely scanned in this area. In other words, an object detected in an area between the front end of the vehicle and the center point or B-pillar during the incomplete scan along the longitudinal side of the vehicle is displayed on the display unit as a potential collision object for the corresponding front outer area of ​​the vehicle.Similarly, environmental information for the area along the vehicle's longitudinal side between the center or B-pillar and a rear end can be displayed as rear outer area environmental information on the display unit, provided the environmental information along the longitudinal side has not been fully scanned. By displaying a potential collision hazard at the front or rear outer area of ​​the vehicle when an object is detected in the incompletely scanned area, the driver will intuitively steer the vehicle away from that side to avoid a collision. This allows collision protection to be provided even with incomplete environmental information, although the driver does not directly see any information about the environment along the vehicle's longitudinal side on the display unit.

[0013] According to another embodiment, the environmental information for the area along the vehicle's longitudinal side is displayed on the vehicle's display unit in an area corresponding to the vehicle's longitudinal side as soon as the environmental information along the longitudinal side has been completely scanned. Otherwise, the incompletely captured environmental information is displayed on the front outer or rear outer area of ​​the corresponding side of the vehicle. Thus, the driver can always be shown reliable information about the vehicle's surroundings on the display unit.

[0014] The sensor for detecting the area along the vehicle's side can be positioned laterally at the front or rear of the vehicle and designed to capture sensor data in the transverse direction. By scanning the area with the sensor as the vehicle moves, a map of the area along the vehicle's side can be created. Taking the vehicle's movement into account, this map can be constructed with respect to a fixed coordinate system. From this, and considering the vehicle's movement, environmental information related to the vehicle can be provided, even for areas not currently detected by the vehicle's sensors. This allows a relatively small number of sensors to detect a large area.

[0015] According to one embodiment, the environmental information is displayed on the display unit as a top view of a symbolically represented vehicle with environmental sectors surrounding the vehicle. Each environmental sector is assigned its own set of environmental information. The way the assigned environmental sector is displayed depends on the environmental information. For example, the environmental sector can be displayed in a first way if no environmental information is shown for that sector, i.e., if no reliable environmental information is available. In this first way, the corresponding environmental sector can be hidden, i.e., it is indistinguishable from the background on the display unit. The environmental sector can be displayed in a second way if, according to the environmental information, no object is present in that sector.The second type of display is chosen when reliable environmental information indicates that no object is present in the area. This second display can be achieved, for example, by coloring the area gray. This intuitively conveys to the driver that the area is being monitored, but that no collision hazard is currently present. A third type of display is used when the environmental information indicates that an object is present. For instance, the area can be colored differently depending on the distance to the object. For example, the area can be colored yellow if the object is approximately more than 30 cm away from the vehicle.The surrounding area sector can be colored red, for example, if the distance to the object is less than 30 cm. By displaying the surroundings in a top-down view of the vehicle with these surrounding areas sectors, the driver gains a quick and intuitive overview of objects in the vehicle's vicinity. This helps prevent collisions with objects when maneuvering and parking the vehicle.

[0016] According to another embodiment, the motion information includes speed information, steering angle information, and / or wheel movement information of the vehicle. The speed information can be provided, for example, by a vehicle speed sensor. Alternatively, distance information from a corresponding vehicle sensor can also be included in the motion information. The steering angle information can be provided, for example, by a vehicle steering angle sensor. The wheel movement information can be determined, for example, individually for each wheel, by capturing its rotational movement and combining it with its circumference. Thus, the vehicle's motion information can be determined cost-effectively using existing sensors. This motion information is also referred to as odometry data.

[0017] The sensor can, for example, be an ultrasonic sensor, a laser sensor, or an image capture sensor. An ultrasonic sensor, in particular, is a reliable and cost-effective method for the relevant distance measurements during parking and maneuvering.

[0018] According to the present invention, a device for a vehicle is further provided, comprising a motion detection unit, an environment detection unit, a display unit, and a processing unit. The motion detection unit serves to acquire motion information from the vehicle, for example, distance traveled and steering angle information. The environment detection unit is capable of determining environmental information for an area along the longitudinal side of the vehicle. This environmental information indicates whether an object is present in the area or not. The environmental information is determined based on sensor information from a sensor on the vehicle and the vehicle's motion information by scanning the area with the sensor as the vehicle moves.The sensor is, for example, an ultrasonic sensor, which is laterally arranged at a front or rear end of the vehicle to acquire sensor information in the transverse direction. The processing unit is coupled with the motion detection unit, the environment detection unit, and the display unit. During operation, the processing unit is able to display information about the vehicle's surroundings on the display unit, based on the environmental information for the area along the vehicle's longitudinal side, in an area that does not correspond to the longitudinal side, if the environmental information along the longitudinal side was incompletely scanned. The device is designed to carry out the method and its embodiments described above and therefore also includes the advantages described above.

[0019] According to the present invention, a vehicle is further provided with the device described above.

[0020] The present invention will be described in detail below with reference to the drawings. Fig. Figure 1 schematically shows a top view of a vehicle according to an embodiment of the present invention. Fig. 2, Fig. 3 and Fig. Figure 5 schematically illustrates a parking or maneuvering operation of a vehicle. Fig. Figure 4 schematically shows an output on a display unit according to an embodiment of the present invention. Fig. Figure 6 schematically shows a further output on a display unit according to an embodiment of the present invention.

[0021] Fig. Figure 1 shows a vehicle 100, which has a processing unit 101, a display unit 102, and environmental sensors 103-114. The environmental sensors 103-114 can be, for example, ultrasonic sensors capable of determining whether an object is present in a predefined monitoring area. If an object is detected in the respective monitoring area, the ultrasonic sensors can also determine the distance to the object. The environmental sensors 103-114 are coupled to the processing unit 101. Alternatively, the environmental sensors can also include, for example, laser sensors or image acquisition sensors. The environmental sensors 107-110 are arranged, for example, in a bumper of the vehicle 100 to monitor a front area.The environmental sensors 111-114 are arranged, for example, in a rear bumper, to monitor the rear area of ​​the vehicle. Monitoring the area in front of and behind the vehicle using the environmental sensors 107-114 and displaying the sensor information accordingly is also known as parking assistance or park distance control and is a known technology. The number of environmental sensors 107-114 is given in . Fig. Figure 1 is shown for illustrative purposes only and can include any other number. The environmental sensors 103-106 are each located at a lateral end of the vehicle and monitor an area extending laterally and transversely to the side of the vehicle. This lateral end includes, for example, an area in front of the front wheel arch or an area behind the rear wheel arch. For example, environmental sensor 103 is located at the front right of the vehicle 100 and monitors an area in the direction of arrow 115. Environmental sensor 104 is located at the rear right of the vehicle 100 and monitors an area in the direction of arrow 116. Environmental sensors 105 and 106 are located at the rear left and front left of the vehicle 100, respectively, and monitor areas in the direction of arrows 117 and 118.

[0022] The processing unit 101 evaluates the information from the environmental sensors 103-114 and displays the information on the display unit 102 for the vehicle driver. Additionally, the processing unit 101 can issue an acoustic warning signal to the vehicle driver if an object detected by the environmental sensors 103-114 approaches the vehicle 100. The processing unit 101 is also coupled with motion detection sensors of the vehicle 100. For example, the processing unit 101 can be coupled with a steering angle sensor and a distance sensor, such as a tachometer, of the vehicle 100. The operation of the processing unit 101 and the corresponding outputs on the display unit 102 are described below with reference to the Fig. 2-6 will be described in detail.

[0023] Fig. Figure 2 schematically shows a top view of vehicle 100, which is to be parked out of a perpendicular parking space between two other vehicles 201 and 202 by the driver of vehicle 100 in the direction of arrow 204. Furthermore, it shows Fig. 2 an obstacle 203, for example a pillar, a bollard, or any other object in the parking lot. The area in front of the vehicle 100 can be continuously monitored using the environmental sensors 107-110, and the area behind the vehicle 100 can be continuously monitored using the environmental sensors 111-114. However, the lateral areas of the vehicle 100 between the environmental sensors 103 and 104 and 106 and 105, respectively, cannot be continuously monitored. Instead, they are monitored during vehicle movement using the environmental sensors 103-106 by scanning the area along the vehicle's longitudinal side. For example, when the vehicle 100 is moving forward, the environmental sensors 103 and 106 continuously scan areas to the right and left in the direction of arrows 115 and 116, respectively.Sensor 118 and processing unit 101 create an environmental map in which detected obstacles are entered. When the vehicle 100 reverses, sensors 104 and 105 can detect the environments to the right and left of the vehicle in the direction of arrows 116 and 117, respectively, and a corresponding environmental map can be created in which detected obstacles can be entered. Thus, in conjunction with the vehicle's movement, the environmental sensors 103-106 can provide information about objects along the vehicle's side, even for areas not currently being detected. The environmental map therefore essentially acts as a memory of the environmental information acquired during the vehicle's journey.

[0024] Fig. Figure 2 shows vehicle 100, which is to be maneuvered out of a perpendicular parking space between vehicles 201 and 202 in the direction of arrow 204. Since vehicle 100 was parked and stationary, no environmental information is available for the lateral areas of the vehicle along its length. After activation of the processing unit 101, it can only determine, using the environmental sensors 103-106, that there are objects at all four lateral ends of vehicle 100 that could pose a collision risk. This applies to vehicle 202 on the right side of vehicle 100 and vehicle 201 on the left side. Using the environmental sensors 107-114, the processing unit 101 can determine that there are no objects that could pose a collision risk in front of or behind vehicle 100 in the direction of travel.Therefore, if the driver of vehicle 100 sets the vehicle in motion in a straight-ahead direction, no collision hazard object is displayed on the display unit 102. However, if the driver of vehicle 100, as in . Fig. As shown in Figure 3, when the front wheels of vehicle 100 turn to the right and the vehicle simultaneously moves forward, the right side of vehicle 100 approaches the left front corner of vehicle 202. However, based on the environmental information from the environmental sensor 103, the processing unit 101 was able to determine beforehand that a collision-hazardous object was present in the vicinity of vehicle 100, near the front left corner of vehicle 202. This information was entered into a corresponding environmental map, as described above. In combination with the detected movement information of vehicle 100, the processing unit 101 can therefore determine the approach of the right side of vehicle 100 to the left front corner of vehicle 202.However, since, due to the short distance traveled by vehicle 100, only environmental information along the right side of the vehicle, from the front right end to approximately the exterior mirror of vehicle 100, could be determined, a collision-hazardous object is displayed on the display unit 102 in the front right area 405 of vehicle 100. Area 405 lies within the area 404 in front of vehicle 100, which is continuously monitored by sensors 107-110. Although the position of area 405 does not correspond to the actual position of the collision-hazardous object (the actual position would be in the area of ​​the right exterior mirror of vehicle 100), the driver of vehicle 100 is intuitively informed that, in order to avoid a collision, they must move the vehicle further to the left or at least not turn the wheel any further to the right.If the collision hazard were displayed in the area of ​​the right-hand side mirror, the driver could mistakenly assume that there are no other collision hazards along the right side of the vehicle besides the displayed object. However, since the right side of the vehicle has not yet been fully scanned, this cannot be guaranteed. With the [document / description] Fig. In contrast, the selected display 4 intuitively conveys to the driver of vehicle 100 that no precise environmental information is available along the side of the vehicle and therefore special caution is required in this area.

[0025] The in Fig. The areas 402 and 404 shown in front of and behind the vehicle 100, respectively, mark the environmental areas that are continuously monitored by the environmental sensors 107-114. Reliable information is therefore available for areas 402 and 404 immediately after the processing unit 101 is activated, for example, after the ignition of the vehicle 100 is switched on. Therefore, these areas 402 and 404 are displayed as monitored areas on the display unit 102.

[0026] The display unit 102 includes, for example, as shown in Fig. Figure 4 shows a screen 400, for example a liquid crystal display, for outputting colored graphic information. A top view of the vehicle 100 is shown against a background 401, which is displayed in a first color, for example black. Monitored areas 402 and 404 in front of and behind the vehicle 100 are shown in a second color, for example gray. Area 402 shows the area monitored by the environmental sensors 111-114. Area 404 shows the area in front of the vehicle 100 monitored by the environmental sensors 107-110. In areas 402 and 404, individual segments in which objects in the vicinity of the vehicle 100 have been detected can be displayed in a third color. Depending on the distance of the detected objects, the third color could be, for example, yellow or red.For example, yellow can indicate that an object was detected at a distance of more than 30cm, and red can indicate that an object was detected at a distance of less than 30cm.

[0027] Fig. Figure 5 shows vehicle 100 after it has driven out of the parking space along route 204. While vehicle 100 was moving along route 204, the environmental sensors 103 and 106 continuously monitored the right and left areas in the direction of arrows 115 and 118, respectively. The processing unit 101 used this sensor information and the vehicle 100's movement information, which includes, for example, the vehicle's steering angle and the distance traveled, to construct an environmental map. For the in Fig. The arrangement shown in Figure 5 depicts the environment map constructed by the processing unit 101, showing objects in the area between the right B-pillar of vehicle 100 and the right rear end of vehicle 100. Since vehicle 100 has moved at least one full vehicle length after processing unit 101 was switched on, processing unit 101 has complete environmental information along the sides of vehicle 100. Therefore, as shown in Figure 5, the following objects are displayed: Fig. As shown in Figure 6, monitoring areas 403 and 406 along the left and right sides of vehicle 100, respectively, are now also shown. Collision-hazardous objects detected in the area between the right B-pillar and the right rear end of vehicle 100 are represented by corresponding segments 407 and 408 in the monitored area 406. Furthermore, vehicle 100 moves as shown in Fig.As shown in Figure 5, the vehicle is moving towards object 203, which is signaled to the driver of vehicle 100 by the display of segment 409 at the front left in the monitored area 404. Due to the collision-hazardous objects in areas 407-409, the driver recognizes that he must carefully move vehicle 100 to the right in order to avoid object 203 and to maintain sufficient distance from vehicle 202.

[0028] By mapping objects along the longitudinal side of the vehicle 100 onto a segment of a front outer or rear outer area of ​​the vehicle, for example, segment 405, as long as the longitudinal side of the vehicle has not yet been fully scanned, instead of displaying the collision-hazardous object in the actual area, it is possible to avoid the driver mistakenly assuming that no other objects are present along the longitudinal sides of the vehicle besides the displayed collision-hazardous object. By displaying the collision-hazardous object as a hazard in the corner area of ​​the vehicle 100, the driver can still be warned of a collision in this situation. If an object is detected due to incomplete scanning along the longitudinal side of the vehicle, it is assigned to the nearest front or rear outer area, i.e.,An object detected in the area between the front right end and the right B-pillar of the vehicle is assigned to the front outer area; an object between the B-pillar and the rear right end of the vehicle is assigned to the rear outer area, and so on. This assignment creates a display that intuitively guides the driver to avoid the object.
