Definitions
- Method for forecasting at least one traffic light switching state during a journey of a motor vehicle as well as control device, motor vehicle and server device
- the invention relates to a method for predicting or forecasting a traffic light switching state of a traffic light.
- the prognosis can be riding ⁇ found during a drive of a motor vehicle.
- a disadvantage in the modeling of the switching behavior of a single traffic light is that although the relative switching times can be determined within a switching cycle, but the absolute times at which a traffic light switches, are not known. So approaching a motor vehicle traffic lights and it is not known at what stage of the switching cycle is even, then, can not be her mask before ⁇ means of such a model when the light turns next time because the model is synchronized only with the traffic lights got to.
- the invention provides a method for forecasting or predicting a traffic light switching state of at least one traffic light.
- the method is initially described below for a single traffic light.
- the procedure can be extended accordingly for several traffic lights.
- the method predicts the traffic light switching state for a motor vehicle that travels along a driving route ahead of the traffic light and leading to the traffic light.
- By means of the method it is possible to perform said "synchro nize ⁇ " in a switching cycle of the traffic lights so that the current phase of the switching cycle is known.
- the syn chronization is done at a holding point along the
- the route is preceded by the traffic light, so is first passed by the power ⁇ vehicle before the motor vehicle approaches the traffic light.
- the synchronization is based on a triggering event at the breakpoint.
- the triggering event may be, for example, driving off or starting at the breakpoint.
- the switching ⁇ behave.
- the forecast of the switching behavior refers to the expected passage direction in which the traffic light will be passed by the vehicle.
- the switching behavior is described by means of a frequency distribution.
- the frequency distribution indicates a respective number of traffic light switching states (eg, "red” or "green") observed in the past for different time intervals that have elapsed since the triggering event.
- the frequency distribution thus relates relatively to the event time of the triggering event.
- a time interval For example, you can specify: 10 seconds after the triggering event or 20 seconds after the triggering event or 30 seconds after the triggering event.
- Each time interval is assigned by the frequency distribution, how often or with what probability a certain traffic light switching state exists (eg "75% red", "80% red”).
- the frequency can be used to convert the probability, for example, by assigning the largest number a probability value of 100% or 1 and the remaining values a smaller probability value in proportion to it.
- the frequency distribution only indicates in which time interval (in relation to the event time point) this traffic light has which traffic light switching state.
- the frequency distribution takes into account the passage direction at the traffic light. For example, it is distinguished whether at the traffic light the traffic light switching state for a straight ahead or for
- the passage direction thus indicates via which possible breakpoint of the intersection the motor vehicle reaches the intersection and to which next stop of the next traffic light the motor vehicle leaves the intersection.
- the method provides that at the breakpoint the triggering event is actually detected and an arrival time is determined at the traffic light and is predicted on the basis of the frequency distribution of the traffic light switching state for the expected passage direction and for the calculated time of arrival. Determining may be computation or may be by sorting or searching within the frequency distribution.
- Trigger event is detected, a traffic light switching state of a following on the route or downlink traffic lights for a particular passage direction and for vo ⁇ expected arrival time can be predicted or forecast.
- the invention also includes developments, the characteristics of which provide additional advantages. Approaches a motor vehicle of a junction, so must to
- Predicting the traffic light switching state are determined in which passage direction the motor vehicle will pass the traffic light, ie where the route will lead along.
- a Wei ⁇ tertician provides that as the passage toward a likely route or signaled by a Navigati ⁇ ons Rhein the motor vehicle route is used. For example, the most probable route may be along a major road, ie the largest road may be used. It can also provide traffic statistics to determine the most likely
- a refinement provides that a matrix is provided which, starting from a plurality of possible stopping points, indicates a respective frequency distribution of the traffic light switching state for possible passage directions, in each case for at least one subsequent traffic light.
- the matrix preferably indicates in the lines the breakpoints with observed trigger events and in the columns breakpoints at the subsequent traffic lights together with a passage direction / turn direction after the traffic light.
- the passage direction can be designated or specified with the next breakpoint, which follows the departure point at the breakpoint of the current traffic light in the respective passage direction.
- the cells of the matrix thus give a frequency distribution of the traffic light state of the subsequent traffic light together with the passage direction (column) for different time intervals, which in the
- a frequency distribution is provided for at least one further stopping point along the route to another triggering event, and the frequency distributions of each stopping point at which the respective triggering event was detected are combined to predict the traffic light switching state by the frequency distribution of the last stopping point with detected triggering event is determined and each remaining frequency distribution is adjusted with a respectively associated time offset which corresponds to the travel time actually observed during the respective journey up to the triggering event at the last breakpoint, ie the departure at the last breakpoint. speaks. So it always counts the start at the last stop with stop / stop. All other breakpoints with a start after a stop / stop are related to the last start / stop (triggering event) over the time offset.
- the said individualized most probable path can also be determined. For this purpose, it is only necessary, the frequency distributions stored in the matrix for each passage direction regardless of the Sum up time component. In this case, one can restrict the summation to the proportions of the frequency distributions originating from the driver, the motor vehicle or several or all participating vehicles.
- Stop phase or red phase at the traffic light or during driving in the direction of or near the traffic light an actual traffic light switching state of the traffic light is detected and based on the respectively detected actual traffic light switching state and the respective time interval since detecting the triggering event at one in the respective trip upstream breakpoint the associated frequency distribution is updated. It is therefore counted during a hold phase or red phase at the traffic light, i. updated in the frequency distribution, the number of observed traffic lights switching states. It should be noted here that during a single journey it is preferable to determine not only for a single point in time the then detectable actual traffic light switching state, but for a whole time interval, i. for several times or more time intervals, in each case the actual traffic light switching state is determined. So stops the motor vehicle at the traffic light, so this is obviously red, so for the
- the frequency distribution can be detected by repeated passing or driving off the route.
- a threshold value it can be specified here from when this frequency distribution is accepted as valid, ie contains enough empirical observation data. For example, this can be based on the number of actually detected time intervals of traffic light switching states.
- the Frequency ⁇ distribution (eg via a histogram estimated) can therefore be completely rebuilt. There is no pre-assignment needed. Only when a quality criterion such. B. "More than x observations" (x is the threshold) is reached, the histogram is used.
- a refinement provides that the actual, actual traffic light switching state of the traffic light is detected even during an approach to the traffic light by means of a detection device and the frequency distributions are updated on the basis of the detected actual traffic light switching state.
- the current actual traffic light switching state of the respective traffic light is detected together with the respective passage direction (eg green right-turn arrow with red main traffic light) and the frequency distribution is updated on this basis. If the detection device does not provide this accuracy, it is also possible to update the update of the frequency distribution only after the observed passage of the vehicle through the intersection.
- the traffic light condition data eg camera images of the traffic light
- the observed behavior of the motor vehicle eg, "stopped and then left bent”
- a refinement provides that from at least one further motor vehicle, status data regarding a respective actual traffic light switching state of the traffic light detected by the further motor vehicle, e.g.
- the frequency distributions are updated based on the status data.
- the traffic light switching state can also be predicted if it is not within the detection range of the motor vehicle itself, because this has never passed the traffic light, for example.
- the status data for example: a) the complete frequency distributions can be transmitted from the other vehicles and these can be transferred to the corresponding (same breakpoint and same traffic light with the same stoplight) Passage direction) are added to their own frequency distributions; (b) extracts from the other vehicles extracts of a frequency distribution from a certain point in time of the past; Remainder as a); c) instead of the frequency distributions, the driving observations can be transmitted from the other vehicles (starting at GPS position XY1 and Hl clock.
- the invention In connection with the use of several motor vehicles for generating the frequency distributions, the invention also provides for a central recording of the status data and redistribution from / to the connected vehicles.
- a server device for operating, for example, on the Internet is provided by the invention.
- the server apparatus is adapted from a plurality of vehicles each driving data relating to a predetermined triggering event at a breakpoint and to ⁇ status data relating to a respective detected by the motor vehicle traffic signal state of a passed in a passage direction of traffic light with time data relating to receive a respective detection time of the detected traffic light switching state and with reference to the Condition data and the time data of all motor vehicles to the trigger event and the passage ⁇ direction to produce and provide a frequency distribution, the frequency distribution a respective number the observed traffic light switching states for various time intervals ⁇ Liche indicating that have passed since the trigger event.
- the server device may be based on a computer or a computer network. The described method steps can be performed by the server device on the basis of a computer program for the server device.
- the frequency distribution described so far provides that the switching cycle of each traffic light is operated unchanged. But there are also traffic lights whose switching cycle is switched over during the course of the day and / or on certain days.
- a refinement provides that the frequency distribution is made up of a plurality of frequency distributions, which are provided for different absolute time intervals, for example, times of the day (morning, noon, afternoon, evening, night, respectively defined by start and end times) or days of the week depending on the date and / or or the time is selected.

- a traffic service for example via the Internet.
- Traffic-controlled traffic lights can be taken into account, which react to the traffic density.
- the said breakpoint for which the triggering event is defined should be chosen such that there is a possible breakpoint
- Tripping event correlated with the switching cycle of the subsequent traffic light is provided as a stopping point and the off ⁇ solvent event is a starting off on the upstream traffic.
- the triggering event is then a start-up of the motor vehicle after the green light of the traffic light. This can be detected, for example, based on the driving speed of the motor vehicle. Is a possible criterion for this is that for a predetermined minimum period of time, for example 1 second, the driving speed consistently greater than a predetermined Min ⁇ least speed, for example 1 m / s, salmuss after previously a predetermined minimum holding time (standstill) to the Hal ⁇ point has been recognized.
- traffic lights are synchronized with respect to their switching behavior so that the unique Detek- animals of the triggering event (green switching a first traffic light) a forecast of the traffic signal state of or several subsequent traffic lights.
- a possible alternative breakpoint may be, for example, a railroad crossing, in which case the triggering event may be the opening of the railway barrier.
- a possible breakpoint may be a bascule bridge or lift bridge on a river, in which case the triggering event may be the release of the bridge after a lockout.

- FIG. 4 further illustrates that at breakpoint A not only for the next traffic light 32 (passage A2), but also for at least one further traffic light 32 ⁇ along the route 11 (see FIG. 2) there is also a frequency distribution 16 ⁇ with a number 31 on observations, ie a probability P for whose traffic light state S can be specified. In the underlying example, this is the traffic light 32 ⁇ for the passage A3: H - L.
- the frequency distribution 16 ⁇ provided for this purpose starts from the breakpoint A (breakpoint 13) and the triggering event 14 that was detected at the detection time TO.
- the motor vehicle 10 must also stop at the stop E (stop 13 ⁇ ) at the traffic light 32 for the passage A2, because the traffic light 32 is switched to red, then the subsequent green-switching the traffic light 32 for the breakpoint 13 ⁇ the traffic light 32nd also represent a triggering event 14 ⁇ .

- the traffic light 12 switches to green, this is detected by the motor vehicle 10 as the trigger event 14, and thus the measurement of the time period 17 is started, that is to say the time difference ⁇ since the detection time TO.
- an absolute time specification can be given, in the example Friday FR, with the month m, the day d, the hour h and the minutes min. Since a passage 37 results without stopping, the feature vector 36 is formed in the example only for one time.
