Abstract

A method for operating a vehicle, a risk parameter being ascertained for a driving route section of a driving route of the vehicle, the risk parameter including an accident probability of the vehicle for the driving route section, the vehicle being controlled at least in an assisted manner as a function of the risk parameter, to reduce the accident probability for the driving route section. Also described is a device for operating a vehicle and a corresponding computer readable medium having a computer program.

First claim

1 - 8 . (canceled)

9 . A method for operating a vehicle, the method comprising:
ascertaining a risk parameter for a driving route section of a driving route of the vehicle, the risk parameter including an accident probability of the vehicle for the driving route section; and controlling the vehicle at least in an assisted manner as a function of the risk parameter, so as to reduce the accident probability for the driving route section.

10 . The method of claim 9 , wherein an additional safety distance is added as a function of the risk parameter to a predetermined safety distance of a distance control device, which is for regulating a distance between the vehicle and an immediately preceding vehicle.

11 . The method of claim 9 , wherein, when the driving route includes multiple traffic lanes, the ascertainment of the risk parameter includes ascertaining a respective traffic lane risk parameter for at least some of the multiple traffic lanes, the respective traffic lane risk parameter including an accident probability of the vehicle for the respective traffic lane.

12 . The method of claim 11 , wherein, if the traffic lane risk parameter of the traffic lane in which the vehicle is presently traveling is greater than the traffic lane risk parameter of an adjacent traffic lane, the control of the vehicle includes a traffic lane change from the present traffic lane to the adjacent traffic lane.

13 . The method of claim 9 , wherein the risk parameter is ascertained based on data selected from surroundings sensor data of a surroundings sensor of the vehicle for detecting the vehicle surroundings, map data of a digital map, traffic data, vehicle data from an additional vehicle, environmental data.

14 . The method of claim 9 , wherein the ascertainment of the risk parameter includes ascertaining a vehicle density of a traffic lane.

15 . A device for operating a vehicle, comprising:
an ascertaining arrangement to ascertain a risk parameter for a driving route section of a driving route of the vehicle, the risk parameter including an accident probability of the vehicle for the driving route section; and a control system to control the vehicle at least in an assisted manner as a function of the risk parameter, so as to reduce the accident probability for the driving route section.

16 . A computer readable medium having a computer program, which is executable by a processor, comprising:
a program code arrangement having program code for operating a vehicle, by performing the following:
ascertaining a risk parameter for a driving route section of a driving route of the vehicle, the risk parameter including an accident probability of the vehicle for the driving route section; and
controlling the vehicle at least in an assisted manner as a function of the risk parameter, so as to reduce the accident probability for the driving route section.
