Claim Text:
1. A method for detecting objects in an environment of a vehicle, the method comprising: ascertaining at least one reflection pattern, which is stored or programmed in a memory or circuit, for at least one object class, wherein a reflection pattern for a mapping geometry of a pulse echo measurement assigns to each parameter value tuple that characterizes an object of the object class in the environment an expected transit time at which an echo pulse is expected in an echo signal if only a corresponding object characterized by the parameter value tuple is present in the environment; performing pulse echo measurements for different transmitter/receiver geometries; detecting echo signals in the pulse echo measurements; calculating weights for different objects of the corresponding class characterized by the parameter value tuple in that, for each echo signal, one or more weight values are ascertained using the echo signal value or echo signal values for a point or points in time corresponding to an expected transit time or transit times that is or are associated with the parameter value tuple using the reflection pattern associated with the echo signal; summing the weight values ascertained to form a weight; and ascertaining a presence of objects of the at least one object class using the weights ascertained.
