Control system and method for determining an irregularity of a road surface

A control method, which in an own vehicle recognises vehicles driving in front based on environmental data obtained from at least one environmental sensor (110) disposed on the own vehicle, with the steps of:

• providing an electronic controller (200) in the own vehicle (ego) by means of the at least one environmental sensor (110) with environmental data reflecting the area (115) in front of the own vehicle,
• detecting another vehicle (alter) participating in traffic in front of the own vehicle (ego) with the at least one environmental sensor (110) during a predetermined time period or continuously,
• calculating a vertical position change of the other vehicle (alter), and
• if a vertical position change of the other vehicle (alter) is recognised, outputting a signal (255), which is suitable to warn a driver of the own vehicle (ego) of a vertical irregularity in the road surface, and/or adjusting a speed and/or a vehicle setting of the own vehicle (ego) in response to the vertical irregularity in the road surface.

A control method for detecting other vehicles driving in front of an own vehicle on a road surface, comprising:

• capturing environmental data at first and second times each reflecting an area in front of the own vehicle and including a vertical position of the other vehicle;
• and
• calculating a vertical position change of the other vehicle based on comparing captured environmental data from the first and second times;
• and
• warning a driver of the own vehicle of a vertical irregularity in the road surface in response to the calculated vertical position change.
