Problems solved by technology

When a low-noise vehicle (e.g., a vehicle that makes very little noise while driving) travels at low speeds, pedestrians and other objects may have difficulty recognizing the vehicle's movement because of the low noise it makes, increasing traffic accidents for people with hearing difficulties risks of

Abstract

An apparatus and a method for outputting a protecting sound in a quieting vehicle are provided. The apparatus includes a storage unit that is configured to store a mapping table in which protecting sounds having frequency bands that are exponentially increased for each vehicle speed are mapped, and a controller configured to output the protecting sound of the frequency band that corresponds to the current vehicle speed using the mapping table when the vehicle is being driven by an electric motor.

Description

technical field [0001] The present invention relates to an apparatus and method for outputting a guard sound in a low-noise vehicle, and more particularly, to a technique for outputting a guard sound corresponding to an exponential increase in vehicle speed in a low-noise vehicle. Background technique [0002] Nowadays, with the increasingly serious problem of environmental pollution, various technical fields and industries are competing to develop environmentally friendly energy. In addition, due to the depletion of oil, natural resources, etc., competition for the development of alternative energy sources is intensifying. As a result, automakers are racing to develop the next generation of vehicles. Hybrid vehicles and electric vehicles using batteries as energy sources have been developed. [0003] In particular, a hybrid vehicle is driven by an electric motor when running at a low speed of about 0-20 km / h, an engine is driven when running at a high speed (eg, greater t...
