EXTERNAL LIGHTING EFFECTS FOR A VEHICLE
Examples of the disclosure relate to example devices and methods for a lighting system for a non-internal-combustion-engine (non-ICE) powered vehicle. An example vehicle includes an electric motor for propelling the vehicle. The vehicle also includes an external light source disposed on the outside of the vehicle. The vehicle further includes a controller to monitor a performance parameter of the electric motor and control the external light source to generate a lighting effect that corresponds with the performance parameter of the electric motor.
1 . A non-internal-combustion-engine (non-ICE) powered vehicle, comprising:
an electric motor for propelling the vehicle;
an external light source disposed on the outside of the vehicle; and
a controller to monitor a performance parameter of the electric motor and control the external light source to generate a lighting effect that corresponds with the performance parameter of the electric motor.
2 . The non-ICE powered vehicle of claim 1 , wherein the performance parameter is a torque demand setting and the external light source is controlled to generate an illumination intensity that is proportional to the torque demand setting.
3 . The non-ICE powered vehicle of claim 1 , wherein the performance parameter is a rate of vehicle acceleration or deceleration, and the external light source is controlled to generate an illumination intensity that is proportional to the rate of vehicle acceleration or deceleration.
4 . The non-ICE powered vehicle of claim 1 , comprising an external sound generator, wherein the external light source and the external sound generator are controlled by the controller to create a coordinated audio-visual effect.
5 . The non-ICE powered vehicle of claim 4 , wherein the coordinated audio-visual effect is to simulate a vehicle backfire.
6 . The non-ICE powered vehicle of claim 1 , wherein the external light source comprises a light bar disposed across a back of the vehicle.
7 . The non-ICE powered vehicle of claim 1 , wherein the external light source is disposed below an undercarriage of the vehicle.
8 . The non-ICE powered vehicle of claim 1 , comprising a tube disposed on the vehicle to simulate a vehicle exhaust pipe, wherein the external light source is disposed within the tube.
9 . A method of operating a lighting system for a non-internal-combustion-engine (non-ICE) powered vehicle, comprising:
monitoring a performance parameter corresponding to input of a driver to an electric motor used for propulsion of the vehicle; and
controlling an external light source disposed outside of the vehicle to generate a lighting effect that corresponds with the performance parameter of the electric motor.
10 . The method of claim 9 , wherein the performance parameter is a torque demand setting and controlling the external light source comprises generating an illumination intensity that is proportional to the torque demand setting.
11 . The method of claim 9 , wherein the performance parameter is a rate of vehicle acceleration or deceleration, and controlling the external light source comprises to generating an illumination intensity that is proportional to the rate of vehicle acceleration or deceleration.
12 . The method of claim 9 , comprising controlling an external sound generator in coordination with the controlling of the external light source to create a coordinated audio-visual effect.
13 . The method of claim 12 , wherein the coordinated audio-visual effect simulates a vehicle backfire.
14 . The method of claim 9 , wherein the external light source comprises a light bar disposed across a back of the vehicle.
15 . The method of claim 9 , wherein the external light source is disposed below an undercarriage of the vehicle.
16 . The method of claim 9 , wherein the external light source is disposed within a tube disposed on the vehicle to simulate a vehicle exhaust pipe.
17 . A lighting system for a non-internal-combustion-engine (non-ICE) powered vehicle, comprising:
a light source configured to generate an external lighting effect; and
a controller to monitor a performance parameter of an electric motor and control the light source to generate a lighting effect that corresponds with the performance parameter of the electric motor.
18 . The lighting system of claim 17 , wherein the performance parameter is a torque demand setting and controlling the light source comprises generating an illumination intensity that is proportional to the torque demand setting.
19 . The lighting system of claim 17 , wherein the performance parameter is a rate of vehicle acceleration or deceleration, and controlling the light source comprises generating an illumination intensity that is proportional to the rate of vehicle acceleration or deceleration.
20 . The lighting system of claim 17 , comprising a sound generator to generate an external sound effect, wherein the controller controls the sound generator in coordination with the controlling of the light source to create a coordinated audio-visual effect that simulates a vehicle backfire.
