Definitions

• the present invention relates to a method and a device for displaying safety-relevant information on a display device of a vehicle.
• Modern vehicles may be equipped with a head-up display for displaying information in a driver's field of vision.
• the present invention provides an improved method for displaying safety-relevant information on a display device of a vehicle, a corresponding device and a corresponding computer program according to the main claims.
• Advantageous embodiments will become apparent from the dependent claims and the description below.
• a method for displaying safety-relevant information on a display device of a vehicle comprising the following steps:
• a display device can be understood as a head-up display.
• the display device may be configured to project information onto a windshield of the vehicle and display it as virtual images in a field of view of the driver.
• a reaction test can be understood, for example, as a driver-initiated or vehicle-initiated test for determining the driver response time.
• An emergency brake assistant can be understood to mean a driver assistance function of the vehicle which is designed to brake the vehicle automatically in emergency situations, ie without intervention by the driver.
• An emergency braking reaction time can be understood, for example, as a pre-warning time for triggering the emergency brake assistant.
• the emergency brake assistant can process, for example, the surroundings information, the speed of the vehicle or other suitable parameters with regard to a driving situation of the vehicle.
• the emergency brake marking and the driver intervention marking can be superimposed on or next to the roadway in the map at a position which is dependent on the speed, the environment, the driver reaction time or the emergency braking reaction time.
• the approach described here is based on the recognition that by fading in corresponding markings in a virtual map of a lane, a point in time or a location at which an emergency brake assistant of a vehicle is likely to intervene in a driving event or a driver of the vehicle by reacting just in time can engage in the driving events, can be graphically displayed, for example, depending on an approach of the vehicle to objects located in the vicinity of the vehicle. It can thereby be achieved that the driver can drive faster, especially in bad weather conditions with correspondingly poor visibility, since he thus has an additional control option in the assessment of their own reaction time and the reaction time of the vehicle is available.
• a distance between the driver engagement mark and the emergency braking mark may be changed depending on a change of a distance between the vehicle and a surrounding object. This allows dynamic adaptation of the driver intervention and emergency braking mark to a driving situation of the vehicle.
• an arrow running parallel to the roadway or, additionally or alternatively, pointing in the direction of the emergency braking mark can be superimposed as the driver intervention mark.
• the emergency brake mark can be highlighted particularly effective.
• the method may include a step of setting an aspect ratio of the map using the speed. For example, as the speed increases, the card can be lengthened or, conversely, shortened as the speed decreases. This allows the map to be dynamically adjusted to the rider's visibility required by speed.
• a step of determining the emergency brake response time may be determined by adding the driver response time to a vehicle response time representing a reaction time of the vehicle in processing a driver command.
• the projection can take place in such a way that the markings appear in strip form on a driver-side lateral or lower edge of the windshield.
• the projection can take place in such a way that the markings are displayed at a virtual distance to the windshield, for example by superposition with an actual surroundings of the vehicle.
• the markers can be projected into the field of vision of the driver so that he can perceive the markings without additional head movement.
• At least one object symbol representing an object located on the roadway can be faded in the map.
• the object symbol may represent a further road user located in the vicinity of the vehicle, such as another vehicle, a cyclist or a pedestrian or even obstacles on the roadside, such as a tree, a bridge pier or a street lamp.
• a size of the object icon may be changed depending on a change in a distance between the vehicle and the object. This can effectively highlight the change in distance.
• the method may further comprise a step of masking a non-driver-visible area of the environment in the map.
• the masking can be done, for example, by shading or blurring the non-visible area. This can alert the driver to poor visibility.
• the driver can reduce the vehicle speed accordingly or, for example, take the risk of an emergency brake assistant.
• the approach presented here also creates a device that is designed to perform the steps of a variant of a method presented here in appropriate facilities to drive or implement. Also by this embodiment of the invention in the form of a device, the object underlying the invention can be solved quickly and efficiently.
• a device can be understood as meaning an electrical device which processes sensor signals and outputs control and / or data signals in dependence thereon.
• the device may have an interface, which may be formed in hardware and / or software.
• the interfaces can be part of a so-called system ASIC, for example, which contains a wide variety of functions of the device.
• the interfaces are their own integrated circuits or at least partially consist of discrete components.
• the interfaces may be software modules that are present, for example, on a microcontroller in addition to other software modules.
• the device is used to control the vehicle.
• the device can access, for example, sensor signals such as acceleration, pressure, steering angle or environmental sensor signals.
• the control is effected via actuators such as brake or steering actuators or an engine control unit of the vehicle.
• a computer program product or computer program with program code which can be stored on a machine-readable carrier or storage medium such as a semiconductor memory, a hard disk memory or an optical memory and for carrying out, implementing and / or controlling the steps of the method according to one of the embodiments described above is used, especially when the program product or program is executed on a computer or a device.

• the display will understandably be shown in the right side strip. If, for example, the steering wheel / steering system or the driver's seat position are positioned centrally, the display can be displayed centrally or almost centrally, for example. Thus, the driver can show or hide the size of the display, the position as well as the individual elements.
• the device 102 is configured to provide a speed information 110 representing an actual speed of the vehicle 100, an environment information 112 representing an environment of the vehicle 100, a driver response time 114 representing a reaction time of the driver determined in a reaction test, and an emergency brake response time 116, which represents a response time of an emergency brake assistant of the vehicle 100 when responding to an emergency situation, and to use this data to display on the map 106 an emergency brake marker 118 and a driver intervention marker 120.
• the emergency brake marker 118 illustrated as a lane crossing line represents a time or location on the lane 106 shown in the map where the emergency brake assist is expected to automatically intervene if another vehicle such as a vehicle that precedes the vehicle 100 in the same lane that exceeds the emergency brake mark 118 without the driver of the vehicle 100 previously engaging accordingly.
• the driver engagement mark 120 appears, as shown in FIG. 1, by way of example as an arrow parallel to the road and pointing in the direction of the emergency brake mark 118, which as a vehicle proximity indicator has the function of identifying a time or location of the driver's latest possible intervention before the automatic intervention of the emergency brake assistant.

• the reaction time of the driver can also take place over time.
• the system assumes a bad response time in such a case. If the driver can be closely monitored, the reaction time can be adjusted in real time if the driver should be distracted, for example. It is also conceivable, depending on the season, the route etc. to adjust the reaction time. This can then be taken into account for the calculation of the display. It is also conceivable to calculate the maximum reaction time between the time determined from the test and from the current situation. This maximum reaction time can then be used for the display.
• the device 102 is configured to appropriately highlight a current lane of the vehicle 100 in the map 106, such as by flashing the current lane or by fading in a suitable lane marker 124 on the current lane.

• the emergency brake mark 1 18 is shown here as a rectangular outline around one of the object symbols 122, which represents the intervention threshold of the emergency brake assistant.
• the shape of the outline may depend on which symbols the driver wishes to display in the corresponding fields. For example, if there are only round "symbols" then a round outline is advantageous because it allows the driver to interpret a better look ahead based on the data displayed than when a circle / hexalon, etc. is displayed in a rectangular outline.
• the driver should be given the opportunity to customize the displayed shapes / colors. He could e.g. Show all symbols around but some could e.g. have a red outline and be filled with a different color or he can customize letters within the desired geometric figures themselves.
