A method for providing an environmental map for a vehicle, wherein the environmental map comprises cells, each of which is assigned to portions of the environment of the vehicle and each of which is assigned an obstacle probability that represents the probability that the corresponding portion of the environment is occupied by an obstacle; wherein the vehicle comprises at least two environmental sensors (2a, 2b, 2c), each of which is designed to provide measurement data regarding the occupancy of a region of the environment by an obstacle, referred to as an obstacle region, in the corresponding detection region of the sensor; wherein the measurement data describe obstacle regions which extend over multiple portions of the environment; wherein the detection regions of the environmental sensors (2a, 2b, 2c) at most partly overlap; wherein the method comprises the following steps: receiving the measurement data from the at least two environmental sensors (2a, 2b, 2c); wherein the measurement data of a first environmental sensor (2a, 2b, 2c) identify an obstacle region; determining occupancy probabilities for those portions of the environment that are covered by the identified obstacle region of the measurement data of the first environmental sensor (2a, 2b, 2c), depending on the measurement data from at least a further one of the environmental field sensors (2a, 2b, 2c); wherein an occupancy probability for a portion indicates the probability that the corresponding portion of the environment is occupied by an obstacle; updating the obstacle probability of the environmental map for at least those portions for which the occupancy probability has been determined; characterised in that the occupancy probability for a covered portion which is at a first distance from the detection region of the further sensor (2a, 2b, 2c) is more heavily dependent on the measurement data of the further sensor (2a, 2b, 2c) than the occupancy probability for a covered portion which is at a greater distance than the first distance from the detection region of the further sensor. receiving the measurement data from the at least two environmental sensors (2a, 2b, 2c); wherein the measurement data of a first environmental sensor (2a, 2b, 2c) identify an obstacle region; determining occupancy probabilities for those portions of the environment that are covered by the identified obstacle region of the measurement data of the first environmental sensor (2a, 2b, 2c), depending on the measurement data from at least a further one of the environmental field sensors (2a, 2b, 2c); wherein an occupancy probability for a portion indicates the probability that the corresponding portion of the environment is occupied by an obstacle; updating the obstacle probability of the environmental map for at least those portions for which the occupancy probability has been determined; characterised in that the occupancy probability for a covered portion which is at a first distance from the detection region of the further sensor (2a, 2b, 2c) is more heavily dependent on the measurement data of the further sensor (2a, 2b, 2c) than the occupancy probability for a covered portion which is at a greater distance than the first distance from the detection region of the further sensor.
