- the overtaking process is accelerated in step S2, if the vehicle is driving on a left lane, for example on the left lane of a highway, and a vehicle ahead on a right lane is detected, which threatens to scissors on the left lane.
- the vo ⁇ out-propelled vehicle is a located in front immobility ⁇ mystery object, such as a construction site, or as ⁇ approaching front located moving slower object, such as a slow-moving truck, or is likely to.
- a remaining overtaking time for the ACC-equipped vehicle traveling on the left-hand lane of the highway is calculated to overtake the preceding vehicle if the vehicle ahead on the right-hand lane moves For example, if there is a gap between two trucks, there is a risk of cutting into the left-hand lane, thus making it possible for the two vehicles to collide.

- FIG 2 moves in with the inventive system ACC equipped vehicle 1 on a two-lane road ⁇ SSE, in particular a motorway with a left Fahrstrei ⁇ fen L and a right lane R.
- the equipped with the ACC system vehicle 1 moves in the example presented Darge ⁇ with a driving speed V on the right traffic lane R.
- the traffic situation shown in Figure 2 arises when the vehicle 1 is originally on a left lane L of the highway moves and performs a lane change from the rear approaching vehicle 2 on the same lane to the right to the rear coming fast vehicle 2 on the left lane L to pass. This happens in many cases, especially when equipped with the ACC system vehicle 1 behind a relatively slow vehicle 3 travels behind and this can not overtake.
- the driving speed V of the vehicle evading to the right is lower than the cruising speed V se set in its ACC system.
- the ACC system of the vehicle 1 recognizes a potential overtaking situation after the lane change on the right lane R. the vehicle 1 will overtake at least one vehicle 2 traveling ahead on another lane, namely the left lane L, in an overtaking operation. This is recognized, for example, if the current current driving speed V of the vehicle 1, the driving speed of the preceding vehicle 3 are below the set cruising speed V set of the ACC system of the vehicle 1. In this case, the vehicle 1 threatens the preceding vehicle 3 in an inadmissible way, namely to overtake on the right.
- step S2 prevents the overtaking when the equipped with the ACC system vehicle 1 threatens to overtake the preceding vehicle 3 in an undue right.
- the prevention of the overtaking is preferably carried out automatically by the ACC system of the vehicle 1.

In this way, it is prevented that the vehicle 1 the preceding ⁇ vehicle 3 overtaken on the right lane R respectively happens, so that the preceding vehicle 3 has suffi ⁇ accordingly space to also perform a lane change to the right lane R. In this case, the fast vehicle coming from behind can overtake both vehicles 1, 3 on the left lane L safely.
- the vehicle 1 is equipped with an ACC system which has a sensor unit which detects the vehicle speed V of a vehicle driving ahead ⁇ .

- the behavior of the ACC system by the adapted Ge ⁇ speed is maintained by an adjustable holding time H before the ACC system accelerates the vehicle 1 is improved.
- the adjusted lowered Fahrgeschwindig ⁇ speed for a period of, for example, ten seconds is maintained before the ACC system of the vehicle 1 accelerates again to the set cruising speed V set . If the preceding vehicle 3 accelerates sufficiently, it falls back into the field of view of the ACC sensor system of the ACC system, and control can be performed on the object recognized on the left lane L.
- be ⁇ is in a preferred embodiment of the ACC system by a further sensor unit with a wide reformbe ⁇ rich SB2 the possibility of the hold time ⁇ manoeuvrable to extend as long as not H.
- a mono or stereo camera may be provided, the Ge ⁇ speed of the vehicle V is maintained as long and no acceleration on the cruising speed V set he follows ⁇ as the camera of the vehicle 1, a preceding vehicle 3 outside the narrow field of view SB1 of the darsensors of the ACC system 1 on the left lane L detected. In this case, therefore, no control is performed on the object with insufficient speed information, but acceleration to the set cruise speed V set is prevented. Since, in most cases, the vehicle does not decelerate on the left lane L, a right overtaking operation is surely prevented.
- FIG. 3 shows a further traffic situation in which the method according to the invention is used.
- the vehicle 1 has an ACC system with a sensor unit, comprising the egg ⁇ NEN relatively narrow field of view SB1, as shown in FIG. 3

- the traffic density is particularly on the left lane L of the highway relatively large.
- a slower vehicle such as a truck 4
- the driver of the vehicle 1 moves his vehicle in the right lane R in order not to stress his concentration, whereby typically the driving speed of the vehicles 5-1, 5-2, 5-3, traveling on the left lane L, 5-4, 5-5 is only slightly greater than the speed V of the vehicle equipped with the ACC system 1.
- some of the vehicles 5-i on the left lane L are not in the field of vision SB1 the sensor unit of the ACC system of the vehicle 1, whereas others further vehicles in front are located in the viewing area SB1 of the sensor unit of the ACC system.
- the speed specification can also be derived from vehicles traveling further ahead, located in the field of vision SB1 of the ACC sensor system, for example vehicles 5-4, 5-5.
- vehicles are selected or selected in a medium distance range, for example from a distance El to a distance E2, which are in the field of view SB1 of the ACC sensor system.
- a minimum travel speed of all vehicles of the selected vehicle group that lie between the distance E1 and the distance E2 is detected and used as the control default for the ACC system.
- filtering of the speed signal can preferably be used to increase the comfort of the ACC system.
- the traveling speeds of the vehicle group, at ⁇ play of the vehicles 5-3, 5-4 are calculated for the speed ⁇ handicap of the ACC system.
- Fi gure 3 a traffic situation overtake using typical features can be detected.
- the traveling speed V set of the ACC system 1 is set higher than the speed of the preceding vehicle on the left lane L vehicle or vehicle group column, a potential Matterholsi ⁇ situation is detected.
- a mög ⁇ handy embodiment may be facilitated with the ACC system of the vehicle 1 the driver of the vehicle 1, the interaction by the driver receives an indication of a time for a comfortable lane change to the left lane L of the ACC system.
- the driver can five seconds before the ACC control the speed of the vehicle 1 due to the preceding vehicle 4 redu ⁇ sheet, he keep an indication of the ACC system of the vehicle 1 ⁇ so that it still a comfortable lane change to the left lane L can perform.
- the driver of the vehicle 1 receives from his ACC system a subtle visual indication for making the lane change, for example ⁇ by a lamp in the instrument cluster or in the HUD lights up.
- FIG. 4 schematically shows a further traffic situation in which the method according to the invention can be advantageously used.
- a vehicle 1 equipped with an ACC system moves on a left lane L of a two-lane road, in particular a motorway.
- the passing process of the vehicle 1 can be automatically accelerated if the vehicle 1 travels on a left lane L and a vehicle 7 driving ahead on the right lane R is recognized, wel ⁇ ches threatens on the left lane L at a given time, in particular by approaching a front befind ⁇ pending object, such as the truck 6, the left traveling ⁇ strip physicallyscheren L.
- the preceding vehicle on the right lane R vehicle 7 threatens surgescheren on the left lane L if the preceding vehicle 7 is a in front of it non ⁇ moveable object, such as a construction site, or in front of it moving slower object, such as the truck 6 shown in Figure 4, actually or probably approaches.
- the preceding vehicle on the right Fahrstrei ⁇ fen R 7 vehicle approaches an object in front of it.
- the remaining Sprintzeit is a calculation unit of the ACC system of the vehicle 1 in response to the mo ⁇ mentanen running speed V of the vehicle 1, the Fahrge ⁇ speed of the preceding vehicle on the right lane vehicle 7 and an approach speed calculation ⁇ net with which the vehicle is traveling ahead on the right lane R to the object 7 located in front, in ⁇ play a truck 6 approaches.
- the set Reisege ⁇ speed V set of the vehicle 1 or other control parameters of the ACC system of the vehicle 1 are then changed depending on the calculated remaining overtaking time such that the overtaking can be completed safely.
- the overtaking operation in which the vehicle 1, the preceding vehicle 7 on the left lane L ⁇ overtaken L, performed only if the driver of the vehicle 1, the performing of this overtaking by an input to the ACC system of the vehicle 1 releases and / or no speed limit or speed limit of the highway is exceeded in the overtaking.
- the overtaking situation shown in Figure 4 can be detected by the ACC system of the vehicle 1, when the range of the ACC sensor is sufficient to measure the gap LÜ on the right lane R. In this case, it can be directly recognized that a possible overtaking situation with limited overtaking time is available.
- the traffic situation shown in Figure 4 typically occurs at a rather low traffic volume, which is in larger Distances on the right lane R are slowly moving trucks, which are spaced by gaps. It may happen that a front truck is not yet in the sensor range of the ACC sensor system of the vehicle 1 and the preceding vehicle 7 einschert on the left Fahr ⁇ lane L. However, in one possible embodiment, a similar traffic situation can be deduced from the history of the trucks passing on the right-hand lane R.
- the airspeed and by means of time ⁇ measurement on the average distance between different trucks on the right lane closed or calculated this distance can be concluded after a Ausscheren the preceding vehicle 7 behind a truck 5 on a potential overtake situation with limited overtaking, even if the further preceding truck 6 is not yet in the field of vision SB the ACC sensor of the vehicle 1 is located. Furthermore, it is mög ⁇ Lich that of a Ausschervorgang of the preceding vehicle 7 immediately prior to the truck 5, ie, can be closed by a small distance that an overtake situation exists, which allows an overtaking limited Matterholzeit.
- the time required for the overtaking process is preferably minimized in the range of permissible limit values.
- a maximum allowable acceleration with kickdown is made.
- a dynamic control tuning can be made, which also allows a slight speed overshoot. It is possible that the difference in driving speed to the set in the ACC system travel speed V set is not sufficient to ERS the overtaking within the still available Kochholzeit time close ⁇ . In this case, the set cruising speed V set is not reached over ⁇ to accelerate the overtaking and then fall back on the cruise speed V set in a possible embodiment.
- the ACC system may include a velocity tolerance on the set travel speed V se t / where exceeding the cruising speed Ma ⁇ SSE the speed tolerance is permitted, for example, +10 km / h at an overtaking limited für fürholzeit.
- This tolerance value can be predetermined in a possible embodiment itself.
- the speed tolerance value may be configurable using a user interface.
- the speed tolerance value is implicitly selected in a further possible embodiment from the dynamics of the ACC system, eg the target time gap.
- the function provided by the method according to the invention can be temporarily deactivated when the speed limit is detected and can only be reactivated once a speed limit or speed limit has been removed.
- a mr ⁇ Schende on the road speed limit or speed limit can be detected for example by means of a camera of the vehicle 1 or ⁇ means of the navigation system.
- the overtaking operation is performed only if the driver of the driving tool 1, the implementation of the overtaking process by an input to the ACC system of the vehicle 1 releases.
- ⁇ ser confirmation for carrying out the overtaking maneuver on the part of the ACC system is required to ⁇ by the driver.
- the driver can be given a visual, visual or acoustic indication of the existing detected over ⁇ holsituation. Reacts the driver of the vehicle 1, then by giving, for example, an acceleration command ⁇ "Accelerate” or "Resume", the Sprintholvor ⁇ gear is started without changing the travel speed setting.
- the driver of the vehicle 1 can confirm the passing operation by operating the accelerator pedal.
- the release of overtaking can be active without reference to a particular time ⁇ space after detecting the overtaking situation. If it is detected based on the speed of the preceding vehicle 7, the length of the gap LÜ, the maximum acceleration and velocity of the vehicle 1, that a overhauls ⁇ len of the vehicle 7, provided that this be in the gap LÜ ⁇ place is not possible, overtaking is prevented or aborted.
- the safety in a passing process of a vehicle in different overtaking situations is significantly increased.
- the invention procedural ⁇ ren and the inventive device provides a more comfortable control and easy operation for the driver.
- the functionality of a conventional ACC system is extended by the inventive method to further driving situations, in particular overtaking situations, whereby driver interventions are minimized.
- the avoidance of right-overtaking operations in the case of a highly automated based driving relevant.
- the traffic situation on a neighboring lane is taken into account for deriving a speed specification for the ACC system.
- the inventive method provides an improvement of the overtaking behavior of the vehicle, which is equipped with the ACC system, by an extended situation analysis of the traffic situation.
- the inventive apparatus for increasing the safety during an overtaking maneuver of a vehicle whose traveling speed is controlled by an ACC system may be integrated in a driver assistance system ⁇ .
- the method according to the invention will be explained in connection with exemplary traffic situations, as illustrated in FIGS. 2, 3, 4.
- the invention Ver ⁇ drive is also suitable for a variety of other traffic situations, in particular of potential overtaking situations, on one or more lanes.
- the method according to the invention is also suitable, for example, for country roads with a lane in each direction.
- the approaching speeds of vehicles approaching in the fast lane are also preferably taken into account.
- the overtaking operation is accelerated with the invention shown SEN method, if the equipped with the ACC system vehicle can pass a vehicle traveling ahead in zuläs ⁇ siger manner without risk of collision with the oncoming vehicle.
- the overtaking operation is prevented if the vehicle threatens to overtake the preceding vehicle in unzulässi ⁇ ger se, for example when a collision threatens due to the oncoming vehicle lane on the left with the inventive method.
- Other potentially critical overtaking situations are possible.
- potentially critical overtaking situations can also be detected if a so-called ghost driver meets the vehicle 1 equipped with the ACC system 1 on a motorway on the left-hand lane L.
- the method according to the invention is differentiated between different types of roads, namely, for example, whether it is a two-lane highway or a four-lane highway.
- ⁇ potential overtaking situations can be detected over a different number of lanes in each direction, for example, in a six-lane highway having three lanes in each direction. In this case, different overtaking situations can be taken into account, depending on whether the vehicle is on the left, middle or right lane of the three-lane highway in the direction of travel.
- Complex driving situations or overtaking situations can be detected by means of one or more ACC sensor units with different viewing areas SB and viewing opening angles.
- the ACC system not only has sensor units with a forward-looking field of view SB, but also sensor units with a rearward viewing area SB to recognize from the rear fast approaching vehicles that are critical to a traffic ⁇ or Can lead to overtaking.
- the ACC system of the vehicle 1 has a plurality of ACC sensor units with different viewing ranges SBi and viewing angles ⁇ both forward and backward to detect complex overtaking situations and, in response to the detected complex overtaking situation, either overtaking to accelerate or reduce prevent or delay.
- the ACC system with its sensors can also recognize how many lanes are available on the road, for example, two lanes as in Figures 2, 3, 4 or three lanes of a total of six-lane highway with three Lanes in each direction.
- the ACC system according to the invention can recognize on the basis of sensorily recognized lane markings, in particular lanes, on which lane the vehicle is currently located.
- the ACC sensor system on which lanes, for example, a slowing vehicle ahead is located and on wel ⁇ chem lanes approaching from behind a fast vehicle approaches.
- a complex situation analysis of overtaking ⁇ situation on the basis of the detected lane and the traveling ahead on the various lanes and succeeding vehicles and their absolute speeds and relative speed to the own Vehicle 1 performed in real time.
- an acceleration operation of the own vehicle by changing of control parameters is then either accelerated or delayed or prevented.
- the preceding vehicle 8 approaching the truck 9 can no longer make a lane change to the left because the distance between the slowly overtaking vehicle equipped with the ACC system and the vehicle traveling on the right lane R is too close has become low.
- this potential overtake is detected, in particular at the Ge ⁇ speed of the preceding vehicle in the right lane R slow trucks 9, the speed of the right lane R approaching behind the vehicle 8 and of distance between the truck 9 and the behind it approaching vehicle 8.
- other signals are evaluated in addition to the speed information, crizspielswei ⁇ se optical traffic signals, in particular brake and Blink ⁇ signals.
- the vehicle 1 with respect to egg ⁇ nem preceding vehicle 8 behaves more considerate and allows him, notably a lane change to the left lane L to overtake the significantly slower-moving truck 9. This increases the fluidity of the traffic and provides a more intuitive behavior of the equipped with the ACC system ⁇ vehicle 1.
- the right-ahead vehicle 8 also has an ACC system, after recognizing this specific traffic situation according to Figure 5 optionally additionally own overtaking of the vehicle 8 to overtake the Trucks 9 accelerates.
- the vehicle 1 prevents its overtaking operation relative to the vehicle 8 and at the same time the overtaking of the vehicle 8 is accelerated or abbreviated relative to the preceding truck 9.
- the two ACC systems of the vehicle 1 and the vehicle 8 cooperate in order to optimize the traffic flow.
- This communication can be done via a back-end system or directly via a wireless interface between the two vehicles 1, 8.
- the truck also has an inventive ACC system
- the ACC systems of the vehicle 1, the vehicle. 8 and the truck 9 communicate with each other and on the basis of a predetermined optimization criterion the traffic or driving flow of all affected vehicles, especially the vehicles 1, 8, 9, optimize.
- This co-operative interaction of the ACC systems not only improves traffic flow but also increases safety for all road users. Further embodiments are possible.
- the detected traffic situation or overtaking situation also vehicles of different types and / or priority be Wegsichti ⁇ gen.
- the vehicle 1 may be a in use be ⁇ findaji ambulance and / or a police car.
- a high priority of such a vehicle on the basis of a transmitted signal beispielswei ⁇ se a switched off blue light in the setting of the acceleration and / or deceleration process of equipped with ACC systems other vehicles detected and in the control or regulation of the engine and / or considered by the brake system.
- a particularly kosichtsvol ⁇ les behavior of a vehicle equipped with the ACC system vehicle against such a rescue and / or police car can be reached by the inventive method.
- it can be achieved that a patient transport trolley with high priority is prevented from unnecessary braking and acceleration processes so as to ensure the safety and / or health of the person transported therein.
