Abstract

The present invention relates to a vehicle combustion noise masking control device and a method of using the same. A vehicle combustion noise masking control method includes: receiving driving information of a vehicle; evaluating a frequency of combustion noise generated in the vehicle using the driving information; and outputting a masking sound when the frequency is equal to or greater than a predetermined frequency.

Description

[0001] Citations to related applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2015-0155930 filed in the Korean Intellectual Property Office on Nov. 6, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to vehicle combustion noise masking control devices and methods of using the same. Background technique [0004] Generally, when a vehicle is driven, combustion noise is generated in an engine compartment of the vehicle, and the combustion noise may flow into the interior of the vehicle. Such combustion noise may be generated and propagated to the interior of the vehicle with varying magnitudes depending on factors such as an opening angle of an engine valve associated with engine rotational speed, an accelerator pedal position, the number of passengers, and various temperature conditions inside the vehicle. [0005] Depending on driving cond...
