Abstract

Claims (61)

1 . A vehicle system for providing a driving function for automated longitudinal guidance of a vehicle at a signaling unit, comprising:

a processor of a vehicle guidance system configured to:

determine environmental data, captured by one or more environmental sensors of the vehicle, relating to an environment of the vehicle in front of the vehicle in a direction of travel;

detect, on the basis of the environmental data, a first signaling unit which is in front of the vehicle in the direction of travel on a road used by the vehicle;

determine distance information relating to a temporal and/or spatial distance of the vehicle from the first signaling unit; and

effect or suppress an output of information relating to the first signaling unit on the basis of the distance information;

wherein the processor of the vehicle guidance system is further configured to:

determine, on the basis of the distance information, whether:

(i) the temporal distance of the vehicle from the first signaling unit is less than or equal to a temporal distance threshold value; and

(ii) the spatial distance of the vehicle from the first signaling unit is less than or equal to a spatial distance threshold value; and

prevent an output of an unavailability output relating to the fact that the first signaling unit is not taken into consideration by the driving function during the automated longitudinal guidance of the vehicle when it is determined that:

(i) the temporal distance of the vehicle from the first signaling unit is less than or equal to the temporal distance threshold value; and

prevent the output of the unavailability output relating to the fact that the first signaling unit is not taken into consideration by the driving function during the automated longitudinal guidance of the vehicle when it is determined that:

(ii) the spatial distance of the vehicle from the first signaling unit is less than or equal to the spatial distance threshold value.

2 . The vehicle system according to claim 1 , wherein the processor of the vehicle guidance system is configured to output an unavailability output if it is determined that:

(i) the temporal distance of the vehicle from the first signaling unit is greater than the temporal distance threshold value; and

(ii) the spatial distance of the vehicle from the first signaling unit is greater than the spatial distance threshold value.

3 . The vehicle system according to claim 1 , wherein the temporal distance threshold value and/or the spatial distance threshold value is/are respectively dependent on:

a predefined reaction time of the user of the vehicle for initiating deceleration of the vehicle in response to the output of the unavailability output; and/or

technically possible deceleration of the vehicle.

4 . The vehicle system according to claim 1 , wherein:

the spatial distance threshold value is independent of a driving speed of the vehicle; and/or

the temporal distance threshold value is dependent on the driving speed of the vehicle.

5 . The vehicle system according to claim 4 , wherein

the dependency is that the temporal distance threshold value increases with increasing driving speed.

6 . The vehicle system according to claim 1 , wherein the processor of the vehicle guidance system is configured to:

determine, on the basis of the environmental data, that the vehicle should stop at the first signaling unit;

determine, on the basis of the distance information, that the vehicle is already at such a short temporal and/or spatial distance from the first signaling unit that automated deceleration of the vehicle that is effected by the driving function is no longer possible with respect to the first signaling unit; and

determine, in response, that an unavailability output should be output.

7 . The vehicle system according to claim 1 , wherein the processor of the vehicle guidance system is configured to:

determine position data relating to a position of a stop line of the first signaling unit on the basis of the environmental data and/or on the basis of map data; and/or

determine position data relating to a position of the vehicle, using a position sensor of the vehicle; and

determine the distance information on the basis of the position data.

8 . The vehicle system according to claim 1 , wherein the processor of the vehicle guidance system is configured to:

determine, on the basis of the distance information, whether the temporal and/or spatial distance of the vehicle from the first signaling unit is equal to or less than an output threshold value; and

output information relating to consideration of the first signaling unit during the automated longitudinal guidance of the vehicle only when it is determined that the temporal and/or spatial distance of the vehicle from the first signaling unit is equal to or less than the output threshold value.

9 . The vehicle system according to claim 8 , wherein the processor of the vehicle guidance system is configured to:

output an offer to take the first signaling unit into consideration during the automated longitudinal guidance of the vehicle to the user of the vehicle only when it is determined that the temporal and/or spatial distance of the vehicle from the first signaling unit is equal to or less than the output threshold value.

10 . The vehicle system according to claim 8 , wherein the output threshold value is greater than the sum of:

(i) a reaction period or a reaction distance granted to the user to react to an offer with respect to the consideration of the first signaling unit; and

(ii) a deceleration period or a deceleration distance needed by the driving function to stop the vehicle at the first signaling unit in an automated manner.

11 . The vehicle system according to claim 8 , wherein the output threshold value is less than or equal to 100 meters or 20 seconds.

12 . The vehicle system according to claim 1 , wherein the processor of the vehicle guidance system is configured to:

determine, on the basis of the distance information and/or on the basis of the environmental data, whether the vehicle is in first place at a stop line of the first signaling unit; and

output information relating to consideration of the first signaling unit during the automated longitudinal guidance of the vehicle only when it is determined that the vehicle is in first place at the stop line of the first signaling unit.

13 . The vehicle system according to claim 1 , wherein the processor of the vehicle guidance system is configured to:

output optical, haptic and/or acoustic information relating to the first signaling unit via a user interface of the vehicle.

14 . A method for providing a driving function for automated longitudinal guidance of a vehicle at a signaling unit, the method comprising:

with a processor of a vehicle guidance system:

determining environmental data relating to an environment of the vehicle in front of the vehicle in a direction of travel using one or more environmental sensors of the vehicle;

detecting, on the basis of the environmental data, a first signaling unit which is arranged in front of the vehicle in the direction of travel on a road used by the vehicle;

determining distance information relating to a temporal and/or spatial distance of the vehicle from the first signaling unit; and
