Description

The invention relates to a method for assisting a driver of a motor vehicle when driving the motor vehicle, wherein on a rearview mirror display surface of a rearview mirror of the motor vehicle, an image of a detected by an outdoor camera of the motor vehicle rear traffic space of the motor vehicle. In addition, the invention relates to a motor vehicle for carrying out an aforementioned method, wherein the motor vehicle has a rearview mirror and a Außenraumkamera exhibiting display system and wherein on a rearview mirror display area of the rearview mirror, an image of a detected by means of the exterior camera rear traffic space of the motor vehicle is displayed.

An aforementioned method and an aforementioned motor vehicle are known from a so-called digital rearview mirror having motor vehicle. This digital rear view mirror is used in the motor vehicle instead of a conventional vehicle rearview mirror. In the digital rearview mirror, the mirror surface of the conventional vehicle rearview mirror, which mirror surface allows a driver of the motor vehicle to look into a rear traffic space of the motor vehicle without significant head rotation, is replaced by a display unit with a liquid crystal screen. The known motor vehicle also has an outdoor camera. The exterior camera detects the rear traffic space of the vehicle, and an image of the rear traffic area detected by the exterior camera is displayed on the liquid crystal panel.

The object of the invention is to provide a method of the type mentioned above, which offers improved support of the driver. In addition, it is an object of the invention to provide a motor vehicle of the type mentioned, which supports the driver improved when driving the motor vehicle.

The first object is achieved according to the invention with a method of the type mentioned above and that the rear traffic area of the motor vehicle is analyzed and analysis of the rear traffic space analysis information on the rear traffic space is generated that a physical condition of the driver is analyzed and off the analysis of the physical condition of the driver is a driver analysis information is generated and that at an observation of the rearview mirror by the driver reproducing driver analysis information and at the same time representing an on a collision course with the motor vehicle traffic object reproducing analysis information on the rear traffic space a traffic object image of the traffic object on the rearview mirror display area is marked.

Advantageous developments of the invention are specified in the subclaims.

Of particular advantage in the invention, the targeted information of the driver with respect to a possible, from the rear traffic area, namely of a traffic object in the rear traffic space of the motor vehicle, resulting danger if the driver directs his eyes on the rearview mirror, therefore if the Driver turns his attention to the rearview mirror. This is achieved in a particularly effective manner by linking the driver analysis information with the analysis information about the rear traffic area. The driver analysis information is generated from the analysis of the physical condition of the driver. For this purpose, the physical condition of the driver is first detected and then analyzed. The analysis of the physical condition of the driver affects the body and the physical condition of the driver.

The rearview mirror can be, for example, a left or a right side mirror or an interior mirror of the motor vehicle. It is also conceivable that the method according to the invention is carried out by means of several or all of said mirrors.

The detected by the outdoor camera rear traffic area includes not only the area centered behind the motor vehicle, but also the right and left laterally backward and backward traffic area of the motor vehicle. The outdoor camera can be both a single camera and a camera network consisting of several cameras by means of which the rearward traffic space of the motor vehicle is detected.

The traffic object image of the traffic object in the rear traffic area, which is on a collision course with the motor vehicle, is preferably marked on the rearview mirror display area as long as the traffic object is in collision course. The traffic object image is marked in particular only if the traffic object is on a collision course with the motor vehicle.

It is also conceivable that the traffic object image is only marked if there is additionally a time criticality, ie a temporal criticality, with regard to a possible collision. This means that there is an actual momentary risk of collision between the driver a collision course located traffic object and the motor vehicle. This could for example be the case when the traffic object, which is on a collision course with the motor vehicle, approaches the motor vehicle at very high speed. In this case, there is a time criticality, that is, a temporal criticality, with respect to a possible collision.

In addition, depending on the time criticality, an acoustic and / or haptic signaling to the driver can take place in order to additionally improve the driver's ability to perceive information. It is also conceivable that with increasing urgency, that is increasing time criticality, a cascading, that is graduated, information representation takes place.

In the method according to the invention, depending on the physical condition of the driver, environmental information is combined with specific contents displayed on the rearview mirror. The combination takes place in dependence on the driving context, that is, a current traffic situation in which the motor vehicle is located, and the physical condition of the driver. Thus, depending on the detected driver state, for example, a detected visual distraction of the driver, and the driving context information is transmitted to the driver controlled.

Advantageously, the invention offers a safety benefit through accurate information and warning of the driver of the motor vehicle on the basis of the marking of the traffic object image as a function of the analysis information about the rear traffic space and the driver analysis information. In addition, there is a gain in comfort for the driver, since he is pointed out with the invention early and purposeful to possible required actions, possibly an intervention in the leadership or a change in the leadership of the motor vehicle. The driver is not warned unnecessarily often.

According to an advantageous development of the invention, when the driver analysis information does not observe the rear-view mirror and at the same time displays analysis information about the rear traffic space on a collision course with the traffic object, a warning signal is issued by means of a display device of the rear-view mirror arranged outside the rearview mirror display area , In this way, with the help of the warning signal, first an attention of the driver excited and this are caused to observe the rearview mirror. The warning signal is directed to the driver. The warning is preferably at least as long as there is no observation of the rearview mirror by the driver. The warning is given at most as long as the traffic object is on a collision course. The warning signal can be supplemented by an additional acoustic and / or haptic signaling to the driver.

Another advantageous development of the invention provides that a time-criticality of a possible collision of the collision course with the motor vehicle traffic object is evaluated and that at high Zeitkritikalität both the warning by means of the display device takes place and at the same time the traffic object image is marked on the rearview mirror display area. Time criticality means a temporal critique. A high time criticality exists when a predetermined, for example preset, first criticality threshold is exceeded.

According to an advantageous development of the invention, when the time criticality is further increased, alarm signaling is additionally carried out by means of lighting elements arranged around the driver in the interior of the motor vehicle. A further increased time criticality exists when a predetermined, for example preset, second criticality threshold value is exceeded, the second criticality threshold value being above the first criticality threshold value. That is, in addition to the aforementioned first criticality threshold, the second, higher criticality threshold is exceeded. The second criticality threshold value is reached when the traffic object which is in collision with the motor vehicle has continued to approach the motor vehicle. The alarm signaling is directed to the driver. The alarm signaling can be supplemented by an additional acoustic and / or haptic signaling to the driver.

According to another advantageous embodiment of the invention, in a traffic object image of the traffic object on a respective rearview mirror display area of several rear-view mirrors of the motor vehicle, the respective traffic object image is marked on each of these rearview mirror display surfaces. In this way, a reliable uninterrupted information of the driver is ensured when he averts his gaze from one of several rear-view mirrors, for example from an interior mirror of the motor vehicle, and turns to another the rearview mirror of the motor vehicle, for example a left side mirror of the motor vehicle.

According to another advantageous embodiment of the invention takes place at several existing rear-view mirrors of the motor vehicle Warning signaling by means of a arranged outside the respective rearview mirror display surface display device of that rear-view mirror, which corresponds to the direction in which is located on a collision course traffic object. In this way, by means of the warning signal advantageously not only the attention of the driver can be excited, but the driver is automatically directed to direct his gaze to the rearview mirror, which corresponds to the direction in which the traffic object located on a collision course corresponds , For example, this rearview mirror is the left side mirror of the motor vehicle when the traffic object is another vehicle overtaking the left of the motor vehicle. Or this rearview mirror is, for example, the interior mirror of the motor vehicle, if the traffic object is another vehicle approaching the motor vehicle from behind at high speed.

The above second object is achieved according to the invention with a motor vehicle of the type mentioned above and in that a first evaluation unit for analyzing the rear traffic space and for generating an analysis information on the rear traffic space is present, that with a second evaluation unit for analyzing a physical condition of the Driver and is connected to generate a driver analysis information detection device connected to detect the physical condition of the driver and that a third evaluation unit for evaluating the driver analysis information and the analysis information on the rear traffic space in dependence of each other, depending on the result of this evaluation, a traffic object image on the rearview mirror display area is markable.

The first evaluation unit is connected, for example, to environmental sensors of the motor vehicle, from which it receives additional surroundings information about the rear traffic area, for example information about another motor vehicle approaching from behind, for example another vehicle. Alternatively or additionally, the first evaluation unit may receive such information from, for example, the outdoor camera. For this purpose, for example, the image of the rearward traffic space can be examined, for example with respect to other traffic objects contained therein, by the exterior camera, or such an examination of the image is undertaken by the first evaluation unit. It is also conceivable that the first evaluation unit obtains surroundings information about the rear traffic area via car-to-car communication or generally via car-to-x communication.

The first evaluation unit and / or the second evaluation unit and / or the third evaluation unit can be combined to form an evaluation unit. However, the evaluation units can also be separated from one another and, for example, connected to one another only by means of signal connections.

According to an advantageous development of the invention, the rearview mirror has a display device for warning signaling, which is arranged outside the rearview mirror display area. As a result, a warning signal is advantageously possible without adversely affecting a display on the rearview mirror display area. In addition, the display device can advantageously have warning display elements that can produce, for example, a particularly high attention, such as particularly bright and / or bright color luminous elements. The display device is oriented to allow for driver-directed warning signaling. The display device is preferably located in close spatial proximity to the rearview mirror display area. Preferably, the display device and the rearview mirror display surface adjoin one another directly. The display device may, in particular, comprise a light band encompassing the rearview mirror display surface and comprising light-emitting elements, for example light-emitting diodes (LEDs).
