Abstract: A safety system (10, 64) for safeguarding the surrounding area of a vehicle (50), wherein the safety system (10, 64) comprises an optoelectronic safety sensor (10) for monitoring the surrounding area, a first input (40) connectable to a first kinematic sensor (56) for determining a first speed value for the speed of the vehicle (50), and a control and evaluation unit (34, 64) configured to detect objects in the surrounding area based on sensor data of the optoelectronic safety sensor (10) and to evaluate whether or not the vehicle (50) initiates a safety reaction, taking into account the speed of the vehicle (50), further comprising an inertial measurement unit (38) for determining movement information of the vehicle (50), with the control and evaluation unit (34, 64) being configured to compare the first speed value and the movement information with each other.
