1. Method for contactless obstacle detection for a motor vehicle (10) having a front side door (12) and a rear side door (14), using a single primary obstacle sensor (16) provided on the motor vehicle, the primary obstacle sensor being configured to monitor an opening region (12o) of the front side door (12) and, at least as long as the front side door (12) is closed, also to monitor an opening region (14o) of the rear side door (14),
the method comprising the steps of, performed repeatedly:
determining (S6, S9′; S6, S10) a current maximum allowed opening angle (αmax) for the rear side door (14) based on an output of a monitoring of the opening region (14o) of the rear side door (14) by the primary obstacle sensor (16), and taking into account a current opening state of the front side door (12).
