GENERATION DEVICE FOR VEHICLE-EVOCATIVE SOUND AND GENERATION METHOD FOR VEHICLE-EVOCATIVE SOUND
First Claim
1. A vehicle-evocative sound generation device that outputs vehicle-evocative sound from a sound output part to the outside a vehicle comprising:
- an acquisition part configured to acquire vehicle lane information including vehicle lane number information that specifies the vehicle lane numbers on the road upon which said vehicle is traveling;
a determination part configured to determine a vehicle-evocative sound arrival range over which vehicle-evocative sound outputted from said sound output part is to arrive, on the basis of said acquired vehicle lane information; and
a control part configured to control the output of vehicle-evocative sound from said sound output part to correspond to said determined vehicle-evocative sound arrival range.

Abstract
Based on the current position of a vehicle MV detected by a position detection part 720, an acquisition part 730A acquires vehicle lane information including the vehicle lane number of the road upon which the vehicle MV is traveling, referring to map information contained in a storage part 710; then send it to a determination part 740. Based on the lane information from the part 730A, the part 740 determines the arrival range of vehicle-evocative sound from the vehicle to outside. Subsequently, based on the determined range, a control part 750 calculates predetermined volume of the sound from left and right speakers of a sound output part 760. As a result, the output of the sound is properly controlled, considering to the possibility that a subject to be alerted is present in the surroundings, which changes depending on the lane class of the road upon which the vehicle is traveling.
