Title:
CONTROL DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2019215504
Kind Code:
A
Abstract:
To provide a control device for a vehicle which reduces noise by outputting a noise suppression sound having a phase opposite to that of room noise at appropriate timing during traveling in an automatic driving control mode.SOLUTION: A control device for a vehicle comprises a noise map MP in which a relationship between a target operating state of a vehicle driving device 16 and a noise suppression sound y (t) in the target operation state is set in advance for a vehicle 10 having an automatic driving control mode. And in the case of traveling in an automatic driving control mode, a target engine rotation speed Ne_tgt and the like in the target operation state of the vehicle drive device 16 are obtained as operation control command values (step S10), and the noise suppression sound y(t) against an expected noise d1(t) of a noise source such as an engine 12 and the like corresponding to the target operation state is determined based on the noise map MP (step S20), and generation of a room noise due to an actual operation state of the engine 12 and the like and an output of the noise suppression sound y(t) corresponding to the target operation state from a speaker 24 are controlled to be synchronized (step S30).SELECTED DRAWING: Figure 5
