Abstract

A road vehicle (1) has a drive unit (2) for driving the vehicle (1), a drive unit control device (3) for driving the drive unit (2) and at least one sound generator (4), which has at least one electroacoustic converter (10). The sound generator (4) has an emission pipe (16), which connects the sound generator (4) acoustically and fluidically directly with an emission chamber (17). The an emission chamber (17) emits the sound generated by the converter (10) during the operation of the sound generator (4). Increased reliability of operation is achieved if a generator control device (26) is coupled with the drive unit control device (3) for driving the converter (10) and the generator control device (26) drives the converter (4) as a function of the current operating state of the drive unit (2).
