A driver assistance system for a vehicle is provided. The driver assistance system includes a detecting device, which is designed to detect driving data that characterize the driving state of the vehicle, and a controller, which is designed to process the driving data detected by the detecting device and, if predetermined driving data are present, trigger a braking device to perform autonomous braking of the vehicle. The controller is also designed such that if driving data that indicate an imminent collision with an obstacle are detected, the function of the detecting device is monitored. If the detecting device no longer provides any driving data or plausible driving data to the controller, a continuation of the autonomous braking is triggered, at least until the vehicle has been decelerated to a specified speed.
