Method and control device for determining a movement direction of an object moving towards a vehicle

The method involves receiving two sensor signals from radar sensors (110, 120), where the sensor signals represent speed of an object to be moved adjacent to a vehicle (100) at two signal measuring positions in a left side and a right side or in a front side of the vehicle, respectively. The sensor signals and information about distance between the signal measuring positions are combined for determining a movement direction of the object, where the sensor signals contain information about intensity of radar radiations reflected by the object. Independent claims are also included for the following: (1) a computer program product comprising a program code for executing a method for determining a movement direction of an object to be moved (2) a sensor system comprising a radar sensor arranged in a left side of a vehicle.
