Provision of an Efficient Environmental Map for a Vehicle

摘要

A method provides an environmental map for a vehicle, wherein the environmental map represents a section of the environment and includes cells which are each assigned to a subsection of the environment of the vehicle. Each cell is assigned occupancy information which is based on the probability of the presence of an object in the subsection assigned to the cell in question. The vehicle has a group of at least two driver assistance systems which are each configured to adopt an active and an inactive state and which, in the active state require occupancy information concerning sections of the environment which at least do not overlap completely. The method determines the driver assistance system(s) which is(are) in the active state; determines the section of the environment that the environmental map is intended to represent, on the basis of the section(s) about which the driver assistance system(s) in the active state require(s) occupancy information. In particular, the section of the environment that the environmental map is intended to represent includes the section(s) about which the driver assistance system or the driver assistance systems in the active state require(s) occupancy information when in the active state.
