Abstract

Two or more quiet vehicles traveling together sense each other and communicate to each other the condition of the respective drivers of the vehicles and announce their presence to pedestrians and other motorists using noise sounds. The characteristics of the emitted sounds are selected according to a level of threat presented by the quiet vehicles.

Claims

1. A method of announcing the presence of a plurality of moving quiet vehicles, which are proximate to each other as they move, the method comprising:

determining operating characteristics of a quiet vehicle based on vehicle impairment, optional equipment, and crash-avoidance capabilities;

establishing bi-directional wireless communications with nearby quiet vehicles;

determining operating characteristics of the nearby quiet vehicles, including vehicle impairment, optional equipment, and crash-avoidance capabilities;

for at least one driver of the plurality of moving quiet vehicles, determining a driver'"'"'s impairment;

sampling ambient noise levels and characteristics;

selecting and outputting a distinctive noise correlated to a driver'"'"'s impairment level, vehicle position within the plurality of moving vehicles, and operating characteristics of the quiet vehicle and of the nearby quiet vehicles;

sending a first type of noise to a leading vehicle of the plurality of moving quiet vehicles;

sending a second type of noise to a trailing vehicle of the plurality of moving quiet vehicles; and

generating the first type of noise from the leading vehicle and the second type of noise from the trailing vehicle.

2. The method of claim 1, wherein vehicle impairment comprises at least one of:

tire inflation, brake status, safety-related diagnostic trouble codes, and information regarding engine cylinder misfire.

3. The method of claim 1, wherein, a volume, a timing, and therefore a distance of effective warnings of the first type of noise generated by the leading vehicle is adapted to account for one or more vehicles of the plurality of moving quiet vehicles that are unlikely to perform to normal specifications and thus are likely to have less effective emergency-handling capabilities.

4. The method of claim 1, wherein optional equipment comprises at least one of:

winter tires, optional higher performance brakes, and suspension stiffness for adjustable suspensions.

5. The method of claim 1, wherein crash-avoidance capabilities comprise whether one or more of the plurality of quiet vehicles has an automated-driving ability to swerve around an obstacle to avoid an accident.

6. An apparatus for announcing the presence of a quiet moving vehicle, which moves with a plurality of other quiet vehicles, the apparatus comprising:

a vehicle-to-vehicle transceiver, configured to provide point-to-point wireless communications between quiet vehicles, the point-to-point wireless communications taking place over distances up to about five hundred feet;

a plurality of driver condition sensors, configured to detect and provide information-bearing signals in real time regarding mental and physical conditions of a driver of the vehicle;

a plurality of vehicle control sensors, each sensor configured to provide signals representing the driver'"'"'s operation of a corresponding vehicle operation control device;

a computer coupled to the vehicle-to-vehicle transceiver, the driver condition sensors and the vehicle control sensors;

a noise generator coupled to the computer and configured to, based on information received by the computer from at least one of the vehicle-to-vehicle transceiver, the driver condition sensors, and the vehicle control sensors, generate a noise having characteristics, selected from a plurality of different characteristics responsive to the mental and physical condition of the driver, positions of the vehicles relative to each other, ambient noise, vehicle impairment, optional equipment, and crash-avoidance capabilities.

7. The apparatus of claim 6, wherein vehicle impairment comprises at least one of;

tire inflation, brake status, safety-related diagnostic trouble codes, and information regarding engine cylinder misfire.

8. The apparatus of claim 6, wherein, a volume, a timing, and therefore a distance of effective warnings of the generated noise is adapted to account for one or more vehicles of the plurality of moving quiet vehicles that are unlikely to perform to normal specifications and thus are likely to have less effective emergency-handling capabilities.

9. The apparatus of claim 6, wherein optional equipment comprises at least one of:

winter tires, optional higher performance brakes, and suspension stiffness for adjustable suspensions.

10. The apparatus of claim 6, wherein crash-avoidance capabilities comprise whether one or more of the plurality of quiet vehicles has an automated-driving ability to swerve around an obstacle to avoid an accident.
