1. A method for altering at least one driving parameter of a vehicle during travel, the method comprising:reading in, via an interface to a read-in device, a traffic-sign signal, the traffic-sign signal representing an altered traffic zone, indicated by a traffic sign, at a position;
reading in, via the interface to the read-in device, a map signal that represents a traffic zone, indicated by a map, at the position;
comparing, via a comparator, the traffic-sign signal to the map signal;
providing, via a processor, an alteration signal for altering at least the driving parameter, if a predetermined relationship exists between the traffic-sign signal and the map signal, the driving parameter including at least one of an engine power output, a transmission control, a chassis control, and an economy (ECO) mode; and
altering, based on the alteration signal, the driving parameter, including the at least one of an engine power output, a transmission control, a chassis control, and an economy (ECO) mode.
