Abstract: A vehicular horn device of an existing electromagnetic type is used as a dynamic speaker so as to generate a false engine sound. The shortage of a low-pitched sound in a parametric speaker device is complemented with a false engine sound which the vehicular horn device generates. Thereby, without need of mounting a large-sized dynamic speaker such as a woofer in a vehicle, a false engine sound is generated so as to model for a real engine sound. In addition, as the vehicle approaches a pedestrian, a sound tone of the false engine sound which the pedestrian hears changes, enabling the pedestrian to easily notice the approach or presence of the vehicle.

Abstract: A vehicle presence notification apparatus uses several ultrasonic transducer devices to generate a notice sound by emitting an ultrasonic wave in mid air based on an ultrasonic signal modulated according to an audible sound. At least one of the speaker-use ultrasonic transducer devices is a two-way transducer device that is enabled to perform not only transmission but also reception of an ultrasonic wave. When a vehicle velocity is equal to or greater than a predetermined value, the two-way transducer device is caused to function as an ultrasonic sensor. Thus, even when the generation of any notice sound is unnecessary due to the vehicle velocity being fast, the vehicle presence notification apparatus can be used as an ultrasonic sensor to measure a distance with an obstacle outside of the vehicle.

Abstract: Methods and systems are provided which generate an alarm signal that alerts individuals who may be in the vicinity of a reversing vehicle and that alerts a vehicle operator when the alarm signal is not audible due to high ambient sound levels or detritus covering the alarm transducer. A background noise level in proximity to the vehicle is monitored. A level of the alarm signal is increased as the ambient (or background) sound level rises. Conversely, the level of the alarm signal is reduced as the background noise level decreases. The alarm signal is changed in volume, frequency, or both based on a velocity of the vehicle. A frequency content of the alarm signal may be modified if a spectral profile of an ambient sound field contains spectral components that may mask the alarm signal.
