A method and a device for controlling at least one object detection sensor for a motor vehicle, the at least one sensor being switchable between a plurality of operating modes; a plurality of functions for evaluating the objects detected, using the object detection sensor, being able to access randomly the at least one sensor and a switchover between the operating modes being selected as a function of the instantaneously accessing assistance functions, and a coordinator is provided between the function evaluation devices and the at least one sensor; each function accessing the at least one sensor transmits to the coordinator a biasing probability distribution function, respectively, and the at least one sensor transmits to the coordinator a detection probability density function for each operating mode that is able to be activated, and the coordinator selects the most suitable operating mode for each function accessing the at least one sensor.
