1. A safety system for a motor vehicle, comprising: a sensing arrangement providing sensor signals related to the surrounding environment of the vehicle and related to detection of an animal or a pedestrian; at least one safety means for providing enhancing safety for an occupant of the vehicle; a control means for controlling the safety means depending on the sensor signals from the sensing arrangement; an environment classifying means for classifying the surrounding environment of the vehicle into different predetermined categories on the basis of the sensor signals from the sensing arrangement and for adjusting the control means depending on the predetermined category classified by the environment classifying means, wherein the surrounding environment is the environment surrounding both the vehicle and either a road or highway in which the vehicle operates, wherein the environment includes the environment in which the road or highway is located; wherein, depending on the classified predetermined category, the control means is adjusted with respect to its control of the safety means in the event of the signals being related to the detection of an animal or a pedestrian; wherein the safety means is adapted to provide an animal or pedestrian warning, and the animal or pedestrian warning is deactivated depending on the predetermined category classified by the environment classifying means; wherein the environment classifying means is adapted to determine that the surrounding environment is a city environment and the city environment is a predetermined category; wherein the safety means is adapted to provide an animal warning and the animal warning is completely deactivated if the city environment is determined by the environment classifying means; and wherein the predetermined category is classified on the basis of yaw rate data provided by a yaw sensor of the sensing arrangement.
