Apparatus and method for controlling virtual engine sound in response to auto-cruise speed settings

An apparatus and method for controlling a virtual engine sound in response to auto-cruise speed settings may include: a controller area network (CAN) communication unit configured to receive information on one or more of auto-cruise speed settings and whether an auto-cruise function is activated, and generate a CAN signal; a control unit configured to control a virtual engine sound function in response to the CAN signal; a signal processing unit configured to process and output a virtual engine sound signal according to control of the control unit; and a digital amp unit configured to amplify the virtual engine sound signal outputted from the signal processing unit and produce a virtual engine sound. When the auto-cruise function is activated, in principle virtual engine sounds are not generated, when a driver changes the auto-cruise speed settings, virtual engine sounds can be generated, continuous and monotonous engine sounds can be prevented, and virtual engine sounds being similar to actual engine sounds are generated.
