Motor and vehicle noise simulator e.g. for electric vehicle

摘要

The noise simulator/generator is fitted to a vehicle and is driven by a control which receives information on the speed of the vehicle. Sensors (13) monitor wheel speed, motor speed etc. and the control drives the noise generator to simulate engine noise corresponding to the speed of the vehicle. The noise is produced by loudspeakers inside and outside the vehicle. The noise patterns are stored on a CD or on an audio cassette. A selection of sound types is controlled by a microprocessor and by the driver selection. The system can be fitted to all types of vehicle including boats and aircraft.
