Title: Vehicle presence notification apparatus
Inventor: NAKAYAMA TOSHIAKI
IPC: H04R3/12
Filed: 2011-03-22
Abstract: PROBLEM TO BE SOLVED: To avoid reduction in sound pressure of a notification sound, even if radiation of an ultrasonic wave is hindered when snow or the like sticks to an ultrasonic loudspeaker.SOLUTION: When snow sticks to an ultrasonic wave radiation port of the ultrasonic loudspeaker 3 owing to a snowstorm or a vehicle traveling wind, the ultrasonic wave generated by respective ultrasonic vibrators 12 is reflected by the ultrasonic wave radiation port by the snow or the like sticking to the ultrasonic wave radiation port. As a result of it, reflected sound pressure detected by a reflected sound pressure detecting element 6 is enhanced. Then, a sound pressure reinforcing means 7 enhances the sound pressure of the notification sound generated from a vehicular horn 2, and compensates for sound pressure reduction in the notification sound from a parametric loudspeaker 1 by a sound pressure increase in the notification sound generated from the vehicular horn 2. Thus, even if ultrasonic wave radiation capacity of the ultrasonic loudspeaker 3 is reduced by sticking of the snow or the like, the sound pressure reduction in the notification sound radiated to the surroundings of a vehicle can be avoided, and the presence of the vehicle can be informed to the surroundings.

Filed: 2011-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent a mark from being misidentified as the concealed mark, for example, when sunbeams shining through branches of trees are applied to the mark provided in a vehicle interior.SOLUTION: An imaging means CA takes images of the vehicle interior provided with an auxiliary mark Ma and the mark M1, and a determination means C1 determines whether the auxiliary mark Ma or the mark M1 is concealed, on the basis of imaging data output from the imaging means CA. Consequently, when it is determined that both the auxiliary mark Ma and the mark M1 are concealed, an operation command means M2 outputs an operation command for in-vehicle equipment. This enables the mark M1 to avoid being misidentified as the mark concealed by a driver, because the sunbeams shining through the branches of the trees and the like are applied to the mark M1, and can prevent the output of the operation command that is not intended by the driver.
