Abstract

A visual and/or audio warning is provided during at least slow forward motion of an automobile vehicle. In another aspect, external music is emitted during only slow movement of an electric or hybrid vehicle. Other aspects of an electric or hybrid vehicle employ warning sounds (preferably music) directly from a vehicular outer body panel and/or the electric drive motor.

Claims

1. An automotive vehicle comprising:

a drive motor operable to move the vehicle in a forward direction, the drive motor being one of;

(a) an electric motor, and (b) a hybrid electric/internal combustion motor assembly;

an electrical circuit including at least one sensor operably detecting if the vehicle is moving in the forward direction and at what speed;

at least one controller connected to the circuit and receiving a signal from the at least one sensor;

a sound emanator connected to the circuit; and

an external light connected to the circuit;

the at least one controller automatically causing the sound emanator to emit a musical song external to the vehicle if the sensor senses that the vehicle is moving in a forward direction at or less than a certain speed; and

the at least one controller automatically causing the light to change conditions external to the vehicle if the sensor senses that the vehicle is moving in a forward direction at or less than a certain speed.

2. The vehicle of claim 1, further comprising memory connected to the at least one controller, the musical song is stored in the memory as a default, the at least one controller causing the sound emanator to play the musical song to warn pedestrians of the moving vehicle.

3. The vehicle of claim 1, further comprising memory connected to the at least one controller, a driver-changeable music source interfacing with the memory so a driver can store at least one music file in the memory and change between the music files, the sound emanator emitting the musical song from the music file depending upon that selected by the driver.

4. The vehicle of claim 1, further comprising memory connected to the at least one controller, software operating the controller, and a remote music source using the software to download the musical song to the memory, the sound emanator emitting the musical song to warn pedestrians of the moving vehicle in response to instructions from the software.

5. The vehicle of claim 1, wherein the at least one controller causes the light to flash to warn pedestrians of the moving vehicle.

6. The vehicle of claim 1, wherein the at least one controller causes the light to change colors to warn pedestrians of the moving vehicle.

7. The vehicle of claim 1, wherein the light is located on a front half of the vehicle, further comprising a light located on a rear half of the vehicle which flashes if the vehicle is moving in reverse.

8. The vehicle of claim 1, wherein the at least one controller automatically causes the sound emanator to emit the musical song, and the light to repeatedly change conditions if the drive motor causes the vehicle to move in a rearward direction.

9. The vehicle of claim 1, wherein the sound emanator is an audio speaker, including a vibrating diaphragm, a voice coil and a magnet, the speaker being mounted beneath an outer vehicular body panel, and multiple different musical songs are automatically externally emitted from the speaker in an order selected by a vehicle operator.

10. The vehicle of claim 1, wherein the sound emanator is an outer vehicular body panel.

11. The vehicle of claim 1, wherein the sound emanator is the drive motor.

12. An automotive vehicle comprising:

a speed sensor;

at least one controller receiving a signal from the sensor and determining if the vehicle is moving and if so, if it is moving within a slow speed range;

memory connected to the at least one controller;

an external speaker receiving music signals from the memory if the at least one controller automatically determines that the vehicle is moving within the slow speed range; and

music files being loaded into the memory by vehicle operator, the music signals sent to the speaker being selectable from the music files by the operator, and a default music file being stored in the memory and emitted by the speaker if a music file is not loaded and by the operator.

13. The vehicle of claim 12, further comprising memory connected to the at least one controller, and a remote music source downloading at least one musical song to the memory, the speaker emitting the musical song to warn pedestrians of the moving vehicle.

14. The vehicle of claim 12, further comprising a light flashing to warn pedestrians of the vehicle only if the vehicle is moving in at least a forward direction within the slow speed range.

15. The vehicle of claim 12, further comprising a light changing colors to warn pedestrians of the vehicle moving in at least a forward direction within the slow speed range but not faster.

16. The vehicle of claim 12, wherein the vehicle is an electric vehicle and the speaker is hidden beneath a composite exterior body panel.

17. The vehicle of claim 12, further comprising a communications port connected to the memory and a hand-held remote audio source containing the music files being removeably connected to the port to allow for operator downloading of new music files for playing through the exterior speaker.

18. An automotive vehicle comprising:

a drive motor operable to move the vehicle in a forward direction, the drive motor being one of;

(a) an electric motor, and (b) a hybrid electric/internal combustion motor assembly;

an exterior vehicular body panel;

a vibration source coupled to the body panel; and

a pedestrian warning sound transmitted to the vibration source and causing the body panel to act as an external speaker.

19. The vehicle of claim 18, wherein the sound is a musical song.

20. The vehicle of claim 18, further comprising:

a speed sensor;

at least one controller receiving a signal from the sensor and determining if the vehicle is moving and if so, if it is moving within a slow speed range;

memory connected to the controller;

the body panel receiving musical signals from the memory only if the controller automatically determines that the vehicle is moving within the slow speed range; and

music files being loaded into the memory by vehicle operator, the musical signals sent to the vibration source being selectable from the music files by the operator, and a default music file being stored in the memory.

21. The vehicle of claim 18, further comprising a light flashing to warn pedestrians only if the vehicle is moving in at least a forward direction within the slow speed range.

22. The vehicle of claim 18, wherein the body panel is a vehicular hood.

23. The vehicle of claim 18, wherein the body panel is a fiber-reinforced resin material.

24. An automotive vehicle comprising:

a drive motor operable to move the vehicle, the drive motor being one of;

(a) an electric motor, and (b) a hybrid electric internal combustion motor assembly;

warning signals; and

a controller sending the warning signals to the drive motor which emits a warning sound directly therefrom.

25. The vehicle of claim 24, further comprising memory connected to the controller, the warning signals being driver-pleasing music stored in the memory as a default, and the controller causing the motor to externally emit the music from the drive motor to warn pedestrians of the moving vehicle.

26. The vehicle of claim 24, further comprising:

memory connected to the controller;

a driver-changeable music source interfacing with the memory so a driver can store the warning signals, which are at least one music file, in the memory and change between the music files; and

the motor directly emitting a musical song from the music file depending upon that selected by the driver.

27. A method of warning a pedestrian of otherwise quiet movement of an electric vehicle, the method comprising:

(a) sensing speed of the electric vehicle;

(b) determining if the electric vehicle is moving forward less than a predetermined speed;

(c) automatically transmitting a music file to a sound emitter affixed to the electric vehicle external to a passenger compartment if step (b) is positive;

(d) externally emitting a musical song from the emitter in response to step (c);

(e) repeatedly and automatically changing an external visual indicator if step (b) is positive; and

(f) manually changing music files to be externally emitted as desired by a vehicle operator.

28. The method of claim 27, further comprising only flashing the visual indicator which is a lamp if the vehicle is moving forward at a speed between about 0-15 mph, wherein the sound emitter is a speaker.

29. The method of claim 27, further comprising storing a default musical song for emission by the emitter if the operator does not select a music file.
