Description

The present invention relates to a method and apparatus for assisting a driver of a vehicle on a driving route.

To assist a driver in vehicle guidance, a variety of driver assistance systems are known. It is among other things from the DE 10 2004 030 997 A1 a driver assistance system for high-speed cruises known. A predefined road course is detected and an optimal curve is calculated. In addition, instructions for maintaining the optimum curve are output.

From the DE 10 2006 016 185 A1 For example, a control device for motor vehicles for learning the autonomous driving of a predetermined ideal line is known. The learning is divided into three levels. In the first stage, the driver is actively assisted by the control device in holding the ideal line, ie the system automatically intervenes in the driving sequence. In the second stage, only hints are given while the driver is driving himself. In the third stage, the driver receives an assessment of how well he has followed the ideal line after driving on the track.

From the DE 10 2010 003 985 A1 a method for operating a driver assistance system of a vehicle is known. In the method, driving data describing the current driving situation are determined on the basis of sensors. A vehicle dynamic limit range of the vehicle is determined, which is used as the basis for a driver recommendation for driving.

From the DE 10 2005 055 744 A1 Furthermore, a driver assistance system is known which an information system for detecting data on the traffic infrastructure and the state of the vehicle and an output device for outputting information to the driver known. In particular, the driver assistance system outputs information about a dynamic course of a route.

Finally, out of the DE 10 2012 221 762 A1 a driving maneuver support known. Recommendations for driving maneuvers can be displayed in a head-up display.

The present invention has for its object to provide a method which allows the driver to drive through a route safely and simultaneously fast.

According to the invention this object is achieved by a method having the features of claim 1 and a device having the features of claim 14. Advantageous embodiments and further developments emerge from the dependent claims.

In the method according to the invention, an actual position is determined on which the vehicle is currently on the route. It is also detected when the actual position approaches a position of a relevant point on the route. A value of a parameter which is dependent on the distance of the actual position from the position of the relevant point on the route is determined. A first display element is generated on a display surface as a function of the determined value of the parameter, and at least one display parameter of the first display element is changed as a function of the determined value of the parameter.

According to the invention, the driver can advantageously easily and simply recognize on the basis of the display element generated on the display element that he is ever approaching a relevant point on the route. By changing the display parameter as a function of the determined value of the parameter, the driver can then advantageously estimate the value of the parameter. In particular, the driver can use the display parameter to recognize when he has reached the relevant point on the route. This in turn helps the driver to drive through the track quickly but safely.

In one embodiment, the parameter comprises the distance between the actual position and the position of the relevant point on the route and / or a time required to move from the current position to the position of the relevant point. Both the distance between the actual position and the position of the relevant point, as well as the time required to move from the actual position to the position of the relevant point is dependent on the distance of the actual position of the position of the relevant point. Advantageously, the driver can then choose between the two sizes and have the size preferred by him output via the first display element.

In particular, the determined value of the parameter can be displayed via the display parameter of the first display element, wherein the display parameter comprises a completeness and / or a color of the first display element. In particular, completeness of the first display element is the state of the display element in which all the display parts comprising the first display element are simultaneously displayed on the display surface. The first display element can So include in the complete state several partial display elements. In addition, the partial display elements can also be fully displayed in order to provide a complete first display element. Furthermore, a completeness of the display element may also be a similar representation over the entire surface of the display element. This means, for example, that a display element is complete when the entire area is displayed in the same color or pattern. Alternatively, the display element may also be complete if the entire surface or all subelements of the display element have changed from a first color or a first pattern to a second color or a second pattern. Thus, although the display element can be displayed in terms of area completely. If, however, part of the display element has a different color or pattern than another part of the display element, it is not considered complete. Finally, the first display element can then be displayed completely if the type of representation has assumed a final state, for example a specific filling, a specific pattern and / or a specific color.

In particular, the first display element is fully displayed when the value of the parameter is minimum. This is especially the case if the actual position and the position of the relevant point match. In this case, minimum means in particular the smallest value which the value of the parameter can assume. In this case, the driver is advantageously displayed in a simple manner when he has reached the relevant point. Specifically, the first display element then indicates that the distance between the current position and the position of the relevant point is zero meters, or that the time required to reach the position of the relevant point has expired.

In one embodiment of the method according to the invention, at least one parameter value is set for the value of the parameter. Furthermore, the first display element comprises at least two partial display elements, wherein a first partial display element is generated on the display surface if the determined value of the parameter is smaller than the predetermined parameter value, and wherein a second partial display element is generated on the display surface if the determined value of the parameter is minimal is. This means in particular that the position of the relevant point has been reached. This indicates to the driver the distance and / or time to the position of the relevant point in steps. The display of the first partial display element of the first display element advantageously prepares the driver for the fact that there will be a point relevant to the safe and fast passage of the route within the foreseeable future. The driver is advantageously not surprised by a perturbing relevant point on the track. He is advantageously informed early on that a relevant point is approaching on the line.

Furthermore, the number of distance values and partial display elements may be arbitrary. In particular, the first display element in the full state comprises three partial display elements, wherein the first partial display element is displayed when a first predetermined parameter value is undershot, a second partial display element is displayed, if a second predetermined parameter value is exceeded and a third partial display element is displayed, if the determined value of the parameter is minimal.

In a further refinement, at least one parameter value is again defined for the value of the parameter. The first display element comprises a planar graphic object, wherein a first partial display element comprises a border of the planar graphic object which defines a surface of the planar graphic object and which is generated on the display surface before the set parameter value is reached. A second partial display element comprises a filling of the area, wherein the size of the second partial display element is dependent on the determined value of the parameter, and which is generated on the display area when the predetermined parameter value is undershot. If the route is a closed race track, the first partial display element can already be generated at the start line. This advantageously indicates to the driver that there is even an indication of relevant points on the route. The second partial display element can then be displayed when the driver drives over the starting line with the vehicle. The driver is thus indicated from the beginning that he is approaching a relevant point on the route. In particular, the first partial display element, that is to say the border, is circular, so that the first partial display element defines a circular area. If the specified parameter value is undershot, a circular sector is generated in the circular border, starting from a twelve o'clock position, which increases depending on the determined value of the parameter to the relevant point. The size of the circle sector thus reflects the decreasing distance and / or the decreasing time to the position of the relevant point.

The area of the first display element is filled completely by the second partial display element, in particular, if the value of the parameter is minimal. This is especially the case if the actual position and the position of the relevant point match. The second partial display element may in particular be a circular disk, which completely fills the circular border. So a circle is continuously filled depending on the determined distance. The filling can be realized by patterns and / or colors. As a result, in contrast to the step display, the driver is continuously shown the distance to the relevant point. Once the relevant point has been reached, the next relevant point on the route can be displayed by the first display element. This embodiment of the first display element is advantageously designed as a timer. This allows the driver to intuitively quickly grasp when he has reached the relevant point with the vehicle.

In a further embodiment of the method according to the invention, an acoustic signal is output as a function of the determined value of the parameter, wherein the acoustic signal comprises a repeated reproduction of a sound. As a result, an additional acoustic output to the visual output of the determined value of the parameter via the first display element is advantageously output to the driver. As a result, the driver advantageously does not have to concentrate solely on the display on the display area.

In particular, the smaller the value of the parameter, the shorter the interval between the repeatedly outputted tones, and the continuous tone is output when the value of the parameter is minimum. This means that a continuous tone is output when the relevant point is reached. In this case, the interval based on the visual output in stages, so whenever a certain distance value is reached, be shorter. Alternatively, the interval between the repeatedly output tones may be continuously adjusted to the distance to the relevant point. The acoustic output can be adapted in particular to the visual output. If the visual output is stepped, the acoustic output will also be stepwise. With a continuous visual output, the acoustic output will also be continuous.

In particular, the relevant point comprises a braking point, an acceleration point and / or a steering point on the driving route. This advantageously indicates to the driver when he should ideally brake, accelerate or hit the steering wheel. In this case, the relevant point may be located within a relevant zone, for example a braking, acceleration or steering zone, within which braking, acceleration or steering should be performed. If the driver adheres to the hints of the system, which are displayed on the first display element, he can handle the track quickly and safely. In particular, the point of interest is the point at which braking, acceleration or steering should begin.

In another embodiment of the method according to the invention, the relevant point comprises the beginning of a route section of the route. On the display surface, a second display element is then generated, which displays instructions for the ideal passage of the route section. As a result, the driver is advantageously not only displayed when a certain section of the route begins, but in addition, as he drives through the route section best.

A completed racetrack usually has several sections, which define, for example, the difficulty of having a passage of the respective route section. For example, a long straight line, such as a home straight, is defined as a track section of the track. If the circuit has an S-curve, then the S-curve can also be defined as a section of track. Also simply curves, or so-called chicanes can be track sections of the racetrack.

In particular, the second display element comprises a graphic representation of the route section. The second display element can be designed, for example, as a map representation of the route section. The following section may in particular be a curve on the track, which must be passed through next.

Furthermore, the second display element can comprise as a guide a target line marked in the graphic representation of the route section, which should follow the vehicle for the ideal passage through the route section. The target line thus represents, in particular, an ideal line. The ideal line designates the fastest connection between two points on the route section. It should be noted that the ideal line is not necessarily the shortest line on the route section. In particular curves should be traversed on the ideal line with a large curve radius. As a result, the steering wheel has to be hit only lightly. The intervention in the drive is then minimal, so that the risk that the vehicle drifts or understeers is minimal.

In addition, the positions of other vehicles can be detected on the route section. The positions of the other vehicles are then displayed in the graphical representation of the route section. As a result, the driver can advantageously be shown whether Objects are located on the route section, which must be taken into account in the passage of the route section additional consideration.

In addition, the braking point, the acceleration point and / or the steering point of the route can be represented in the graphical representation of the route section. The driver can thereby be provided an overview of where on the route section further relevant point.

The invention further relates to a device for assisting a driver of a vehicle on a driving route. The device comprises a detection unit, by means of which is detectable when the vehicle approaches a position of a relevant point on the route. Furthermore, the device comprises a determination unit, by means of which an actual position on which the vehicle is currently on the route, and a value of a parameter, which is dependent on the distance of the actual position from the position of the relevant point, can be determined , and a display device with a display surface. By means of a control device, the display device is controlled such that depending on the determined value of the parameter, a display element can be generated on the display surface, wherein by means of a completeness of the generated display element of the determined value of the parameter is reproduced and at least one display parameter of the display element in dependence on the determined value of the parameter is changeable. The device is particularly suitable for carrying out the method according to the invention and therefore has all the advantages of the method.

The display device is in particular a so-called head-up display, in which the display surface is arranged in the windshield of the vehicle.

Alternatively, the display surface may also be arranged on the inside of a visor of a helmet, as worn by racers, for example. In addition, it is also conceivable that the display surface is arranged on the inside of a data glasses. Such data glasses can be worn especially by motorcycle or bicycle riders.

Furthermore, the invention relates to a vehicle, in particular a racing vehicle, with such a device.

The invention will now be explained in detail by means of exemplary embodiments with reference to the drawings.

Related to the 1 and 2 is an embodiment of an inventive device 1 and an arrangement of the device according to the invention 1 in a vehicle 11 shown.

The device according to the invention 1 includes a display device 2 with a display area 3 ,

The display device 2 is with a control device 4 connected, which in turn with a determination unit 5 and a detection unit 6 connected is. The display device 2 is a head-up display, the display area 3 in the windshield of the vehicle 11 is arranged.

By means of the determination unit 5 is an actual position, ie the position on which the vehicle is 11 currently on the route, can be determined. This is done via a position determination by means of GPS signal. Alternatively, the actual position can also be determined via the lane markings. For example, the distance of the vehicle 11 are determined by the lane markings on both sides and from this the actual position can be calculated.

In addition, with the investigation unit 5 a point relevant to the route is determined. Such a relevant point is a braking point, an acceleration point or a steering point. It should also be noted that the relevant point for each actual line on which the vehicle 11 located on the route exists. Furthermore, with the determination unit 5 a value of a parameter that depends on the distance of the actual position of the vehicle 11 from the relevant point on the route is determinable. Such a parameter is the distance of the actual position to the position of the relevant point or a time that is still needed to reach the position of the relevant point starting from the actual position. The distance and / or the time to the relevant point are determined in particular in the longitudinal direction of the route.

Relevant points on the route are important, for example, on completed routes, as they are at racetracks. In order to complete the racetrack safely and at the same time, it is advantageous if the rider knows such relevant points on the route and if he is informed early enough before reaching a relevant point that he will soon reach such a relevant point.

The determination unit 5 is a navigation system that has information about the vehicle 11 in which the device 1 is arranged, has traveled route. From the information, the navigation system determines the relevant points on the route. The relevant points are stored in the navigation system when the route has been completed. Alternatively, these can be calculated when the completed route is known. Once calculated, the relevant points are then stored in a memory unit and are known for future journeys on the same route.

By means of the detection unit 6 is detectable when the vehicle 11 approaching the relevant point on the route.

The control device 4 receives information about that from the investigative unit 5 determined distance to the relevant point. This information is provided by the control device 4 further processed such that on the display surface 3 depending on the determined distance, a display element 7 is produced. This means, first, that at all a display element 7 on the display surface 3 is generated as a function of the determined distance. Furthermore, a display parameter of the generated display element 7 changed depending on the determined distance. This in turn means that if the display element 7 once on the display area 3 has been generated, this is changed when the distance to the relevant point changes on the route.

The display parameter encompasses a completeness of the display element 7 , Alternatively, a color and / or a pattern of the display element 7 to be changed. Completeness is understood to mean that all partial display elements 7.1 to 7.3 , from which the display element 7 be displayed on the display area. Alternatively, by completeness it can also be understood that the color of all partial display elements 7.1 to 7.3 from a first color, for example green, to a second color, for example red. The display element 7 is then considered complete when the color of all sub-panels 7.1 to 7.3 changed from the first color to the second color.

In the 1 and 2 is the display element 7 shown in complete condition. This means that the distance between the actual position and the position of the relevant point is minimal.

Related to the 3a to 3c a first embodiment of the method according to the invention will be explained.

Starting situation is a ride on the vehicle 11 on a closed circuit at high speed. All relevant points on the route are known in advance.

In the in the 3a to 3c As shown, the vehicle is approaching 11 to a curve. The 3a to 3c show the view from the cockpit of the vehicle 11 on the route. In the present example, only the display element 7 and possibly associated lane boundaries generated on the display surface. Everyone else in the 3a to 3c Plotted positions are not displayed to the driver, but merely serve to clarify the driving situation.

In order to drive through the curve safely, a braking process must be initiated before the curve is reached. Before the curve is on the route so a braking point 9 , As for each of the vehicle 11 actually driven line on the route a braking point 9 results, this is in the 3a to 3c drawn as a line. It is first the actual position P1 of the vehicle 11 determined on the route. In the actual position P1, this is the position on which the vehicle 11 actually located on the route.

It is then detected that the actual position P1 of a position P2 of the braking point 9 approaches. This can be done simply by comparing the two known positions P1 and P2 on the route.

In a further step, the value of the distance D between the actual position P1 and the position P2 of the braking point 9 determined.

In the investigation unit 5 In this case, two distance values of the distance D are stored, wherein the first distance value is greater than the second distance value. The distance values can be stored as a function of the speed traveled in the memory unit. Drives the vehicle 11 At a low speed on the curve, can be an indication of the braking point 9 at a short distance to the braking point 9 respectively. Drives the vehicle 11 on the other hand, at high speed towards the curve, an indication of the braking point must already be well before the braking point 9 respectively.

If the value of the distance D falls below the first distance value, as in 3a is shown, both on the right and on the left edge of the display area 3 a first partial display element 7.1 of the first display element 7 generated. It is thus first a function of the determined value of the distance D, a first partial display element 7.1 of the first display element 7 on the display surface 3 generated. The first display element 7 is not displayed completely when the first distance value is undershot. By the display of the first partial display element 7.1 the driver is first indicated that he is at the braking point 9 approaches.

If the determined value of the distance D falls below the second distance value, as in 3b is shown in addition to the first partial display elements 7.1 second partial display element 7.2 next to the first partial display elements 7.1 of the first display element 7 on the display surface 3 generated. Thereby, that the number of displayed partial display elements 7.1 and 7.2 increases with decreasing value of the distance D, the driver is made clear that the value of the distance D to the braking point 9 decreases. In addition, the display element 7 on the display surface 3 changed by adding further partial display elements, also in dependence on the determined distance D.

Has the vehicle 11 the braking point 9 achieved, in addition to the partial display elements 7.1 and 7.2 a third partial display element 7.3 on the display surface 3 generated. The third partial display element 7.3 This represents the largest of all partial display elements 7.1 to 7.3 In addition, the third partial display element 7.3 designed as a bar. As a result, the driver is presented with a barrier, which illustrates to him figuratively that he is the braking point 9 has reached. The complete display element 7 also extends across the display area 3 , This also clarifies to the driver the urgency that he should brake now. In addition, all partial display elements 7.1 to 7.3 shown in red to create a warning effect.

Brakes the driver despite reaching the braking point 9 not off, the full indicator starts 7 to blink. This will make the driver even more clearly aware of the urgency to brake.

The first embodiment of the method according to the invention is characterized in particular by the fact that the display element 7 is completed step-by-step.

The shape of the display element 7 can be adapted to the type of relevant point. If the relevant point is an acceleration point, the display element can 7 displayed in green. In addition, the third partial display element 7.3 an arrow to show the driver that he can press the accelerator pedal. If the relevant point is a steering point, the display element can 7 be displayed bent to the driver to indicate the direction in which to steer.

Alternatively to the completion of the display element 7 by adding partial display elements 7.1 to 7.3 The display element can already below falling below the first distance value in the full number of partial display elements 7.1 to 7.3 are displayed. In this case, then the partial display elements 7.1 red and the partial display elements 7.2 and 7.3 shown in green. This allows the driver from the time at which the distance D between the actual position P1 and the position P2 of the braking point 9 is smaller than the first distance value, it should be pointed out that there are several distance steps.

If the determined value of the distance D then falls below the second distance value, the color of the partial display elements changes 7.2 from green to red. If the distance D is minimal, so has the vehicle 11 reaches the braking point, the color of the third partial display element also changes from green to red.

In reference to 4 a second embodiment of the method according to the invention will be explained.

This is a value of a time that the vehicle 11 from the actual position P1 to the position P2 of the relevant point, in the present example again a braking point 9 , constantly measured. Here again is the driver's view from the cockpit of the vehicle 11 shown.

At the beginning of the journey, ie at the start line of the racetrack, the value of the time falls below the braking point 9 a fixed time value. At this time already a first partial display element 10.1 of the display element 10 on the display surface 3 generated. The first partial display element 10.1 represents a circular line. Through the circle 10.1 A circular area A is defined, which is not filled but empty at the beginning of the journey.

Only when the vehicle 11 falls below the set time value, which happens in the present example, when crossing the start line, in the area A is a second partial display element 10.2 generated. The second partial display element 10.2 has the shape of a circular sector, the size of the circular sector 10.2 depending on the value of the distance D to the braking point 9 is. When comparing the display element 10 with a clock, the replenishment of area A begins at the point at which the time is arranged at twelve o'clock for a clock.

The circular sector 10.2 Starting from the twelve o'clock position, the smaller the value of the time the vehicle is, the larger it gets 11 from the actual position P1 to the position of the brake point 9 needed, will.

Is the area A of the display element 10 completely with the second partial display element 10.2 filled in, is the indicator 10 Completely. The vehicle 11 has the braking point 9 reached.

The driver brakes the vehicle 11 then not off, can the full indicator 10 start flashing again to show the driver the urgency of the necessary braking intervention.

In addition, on the display area 3 the display elements 12 and 13 are displayed. The display element 13 indicates the position of an ideal line of the route. The display element 12 shows the actual position P1 of the vehicle 11 on the route. By a shift of the two display elements 12 and 13 each other then the driver is shown whether he is with the vehicle 11 located on the ideal line of the route.

Additionally or alternatively to the illustrated in the first and second embodiment of the inventive method visual output of the distance D or the time to the braking point 9 via the display elements 7 respectively. 10 , the output can also be made acoustically. The acoustic output can be realized via the repeated output of a tone. An interval between two consecutive tones may then be the distance D or the time to the braking point 9 specify. In 5a In this case, a tone sequence is shown, as it is output, for example, after falling below the first distance value in the first exemplary embodiment. The interval between two consecutive tones is a value in a range of 1.5 s to 1 s. Falls below the vehicle 11 the second distance value, the interval between two consecutive tones becomes shorter as in 5b and has a value in a range of 0.9 s to 0.1 s. Has the vehicle 11 the braking point 9 reached, a continuous tone is output, as in 5c indicated by the solid line.

When the sound is outputted in addition to the continuous time display of the second embodiment, the interval between two consecutive sounds may also be continuous with the braking point depending on the time 9 get shorter.

In the first embodiment, the first display element 7 also in dependence on the determined time and in the second embodiment, the first display element 10 also depending on the determine distance on the display area 3 be generated.

Related to the 6 and 7 Further embodiments of the method according to the invention will be explained.

A completed race track usually has several sections 17 which, for example, defines the difficulty involved in a transit. Thus, a long straight stretch, such as a home straight, is a stretch of road 17 defined the racetrack. If the circuit has an S-curve, the S-curve can also be used as a section of track 17 be defined.

In the present example, a section of track 17 as he is in 7 is shown, a braking point 9 , a steering point 14 and an acceleration point 15 on. The section of the route 17 So includes a curve, where the acceleration point 15 usually located at the apex of a curve.

The beginning 20 of the section of track 17 itself is a relevant point in the present example. This means that the display elements 7 and or 10 the driver on the beginning 20 of the section of track 17 to prepare. Is the beginning 20 of the section of track 17 reached, the display elements 7 and or 10 or their Part display elements 7.1 to 7.3 respectively. 10.1 and 10.2 for the next relevant point 9 . 14 . 15 or 20 on the display surface 3 generated.

Has the vehicle 11 the beginning 20 of the section of track 17 reached is on the display area 3 a second display element 18 generated. Such a display element is in 6 shown. The second display element 18 provides a graphical representation of the route section 17 This is the driver of the course of the section 17 shown before he goes through this.

In addition, the display element comprises 18 a marked target line 16 So the ideal line, which is the vehicle 11 at the passage of the section of the route 17 should follow. The display element 18 provides the driver with instructions for the passage of the section of track 17 The driver is shown as he the section of track 17 should pass through best.

Alternatively, a graphical representation of the in 7 shown section of the route 17 even on the display area 3 be generated. It will then be in addition to the course of the section 17 and the ideal line 16 all relevant points, such as braking point 9 , Steering point 14 and acceleration point 15 displayed. This gives the driver an overview of the distribution of the relevant points 9 . 14 and 15 and the driver can therefore immediately when he enters the stretch of track 17 enters, assessing when to brake, steer and / or accelerate.

In addition, also the positions of other vehicles can be detected and in the display elements 18 or 19 are displayed. This will alert the driver to further hazards arising in the section of the route 17 indicated by other vehicles on the route section, pointed out.

The illustrated embodiments can be easily combined. So it can simultaneously the first display element 7 and 10 on the display surface 3 be generated. As a result, the step-like and continuous distance or time measurement are combined. This gives the indication of the distance to the relevant point 9 . 14 . 15 or 20 more emphasis, so that the driver rather follows the clues of the system. In the case of the output of the sound, however, it is then necessary to decide for either the step-like shortening of the interval of two successive tones or the continuous shortening of the interval.

The display area 3 In addition, the inside of a visor of a helmet, such as a motorcycle helmet, or on the inside of a data glasses may also be arranged. The display will then not be on the head-up display in the vehicle 11 but in the visor of the helmet or on the inside of the data glasses.
