Abstract

A method for displaying information for a user of a vehicle by means of a projection system, which has a projection unit, a control device, a first projection field, and at least one second projection field, wherein the information is transferred from the control device to the projection unit, and wherein the projection system is switched over from a first beam path, in the case of which light beams produced by the projection unit are directed onto the first projection field, to a second beam path, in the case of which light beams produced by the projection unit are directed onto the at least one second projection field, in accordance with the current position of a seat of the user, the light beams produced by the projection unit being deflected to a field of view of the user by the at least one second projection field.

Dependent claims

A method for displaying information for a user of a vehicle by a projection system, comprising:

arranging a first projection field on a windshield of the vehicle,
arranging at least one second projection field on a roof liner of the vehicle, separate from the windshield,
transferring information from a control device of the vehicle to a projection unit, and
switching the projection system between a first beam path and a second beam path based on an orientation of the user of the vehicle,
wherein the first beam path directs light beams produced by the projection unit to the first projection field, the projection system switching to the first beam path when a seat of the user is in a driving position whereby the user is oriented substantially vertically with respect to a chassis of the vehicle, and
wherein the second beam path directs the light beams produced by the projection unit to the at least one second projection field, the projection system switching to the second beam path when the seat of the user is in a comfort position whereby the user is oriented substantially horizontally with respect to the chassis of the vehicle.
