Method for determining a navigation route for a vehicle, in which the following steps are carried out: - providing a plurality of items of road portion information each about at least one road portion to be traveled by the vehicle for the navigation route, - determining at least one item of illumination information for the navigation route, the at least one determined item of illumination information being specific to an illumination of the road portions, - calculating the navigation route based on the provided road portion information and the determined illumination information, a user preset being provided, and, when calculating the navigation route, a selection and evaluation of the provided road portion information for determining the navigation route being carried out by comparing the user preset with the at least one determined item of illumination information, the user preset comprising a specification for a minimum and/or maximum intensity of the illumination of the environment in order to take this specification into account in the evaluation, characterized in that during the determination at least a first item of illumination information about the illumination of the road portions and additionally at least a second item of illumination information about an illumination of at least one environment outside the road portions is determined, and in that the environment outside the road portions is provided in the manner of an environment to be walked through by a driver of the vehicle, sufficient illumination of the environment being used as an evaluation criterion for the calculation. - providing a plurality of items of road portion information each about at least one road portion to be traveled by the vehicle for the navigation route, - determining at least one item of illumination information for the navigation route, the at least one determined item of illumination information being specific to an illumination of the road portions, - calculating the navigation route based on the provided road portion information and the determined illumination information, a user preset being provided, and, when calculating the navigation route, a selection and evaluation of the provided road portion information for determining the navigation route being carried out by comparing the user preset with the at least one determined item of illumination information, the user preset comprising a specification for a minimum and/or maximum intensity of the illumination of the environment in order to take this specification into account in the evaluation, characterized in that during the determination at least a first item of illumination information about the illumination of the road portions and additionally at least a second item of illumination information about an illumination of at least one environment outside the road portions is determined, and in that the environment outside the road portions is provided in the manner of an environment to be walked through by a driver of the vehicle, sufficient illumination of the environment being used as an evaluation criterion for the calculation. a user preset being provided, and, when calculating the navigation route, a selection and evaluation of the provided road portion information for determining the navigation route being carried out by comparing the user preset with the at least one determined item of illumination information, the user preset comprising a specification for a minimum and/or maximum intensity of the illumination of the environment in order to take this specification into account in the evaluation, characterized in that during the determination at least a first item of illumination information about the illumination of the road portions and additionally at least a second item of illumination information about an illumination of at least one environment outside the road portions is determined, and in that the environment outside the road portions is provided in the manner of an environment to be walked through by a driver of the vehicle, sufficient illumination of the environment being used as an evaluation criterion for the calculation.
