Abstract

A vehicular control mode signaling system includes a Driving Automation Level Electronic Control Unit that is communicatively linked to a vehicle computer and a signaling unit that is disposed along the vehicle. The control unit includes a processor, a vehicle controller, an interface controller, and a memory. The processor determines a vehicular control mode based on a comparison of a stored automation nomenclature and operating information received from the vehicle computer. The signaling unit includes at least one signal light that is disposed along the vehicle, and a transmitter that are selectively activated by the processor based on the determined vehicular control mode.

Claims

1. A vehicular control mode signaling system, comprising:

a signaling unit that is disposed along a vehicle; and

a discrete driving automation level electronic control unit that includes;

a vehicle communication unit that is configured to engage an onboard computer system of the vehicle and to receive a vehicle operating information therefrom,

a component interface unit that is communicatively linked to the signaling unit,

a processor for controlling an operation of the control unit, and

a memory that is encoded with instructions for instructing the processor to determine an active control mode of the vehicle, and to selectively activate the signaling unit based on the determined active control mode,

wherein the active control mode includes at least one of a full self-driving automation status, a limited self-driving automation status, a combined function automation status, a function-specific automation status, and a no-automation status.

2. The system of claim 1, wherein the signaling unit includes at least one signal light that is disposed along the vehicle.

3. The system of claim 2, wherein the signal light is configured to illuminate a different color for each of the determined active control modes.

4. The system of claim 1, wherein the signaling unit includes a plurality of signal lights that are disposed along a front end, a back end, a top end, a driver side, and a passenger side of the vehicle.

5. The system of claim 4, wherein the memory is encoded with instructions for ordering the transmitter to also broadcast a portion of the received vehicle operating information to an outside device.

6. The system of claim 1, wherein the signaling unit includes a transmitter that is configured to electronically broadcast the active control mode of the vehicle to an outside device.

7. The system of claim 1, wherein the vehicle communication unit comprises:

a controller area network bus transceiver.

8. The system of claim 1, wherein the vehicle operating information includes, at least one of a vehicle speed, a fuel status, a warning indicator, and an automation systems status.

9. The system of claim 1, wherein the vehicle operating information consists of:

a vehicle speed, a fuel status, a warning indicator, and an automation systems status.

10. A computer-implemented method for providing a notification of active control mode of a vehicle, comprising:

providing a discrete driving automation level electronic control unit;

communicating with an onboard computer system of a vehicle;

receiving operating information about the vehicle;

storing a plurality of active control mode levels within a memory of the electronic control unit;

comparing, via a processor within the electronic control unit, the received operating information with the stored active control mode levels;

determining an active control mode level of the vehicle based on the comparing step; and

selectively activating a signaling unit to illuminate a specific color representing the determined active control mode,

wherein the active control mode includes at least one of a full self-driving automation status, a limited self-driving automation status, a combined function automation status, a function-specific automation status, and a no-automation status.

11. The method of claim 10, wherein selectively activating the signaling unit includes:

instructing a signal light to transition between an on and off configuration.

12. The method of claim 10, wherein selectively activating the signaling unit includes:

instructing a transmitter to send an electronic signal containing the active control mode to an outside device.

13. The method of claim 10, wherein selectively activating the signaling unit includes:

instructing a transmitter to send an electronic signal containing a portion of the received operating information to an outside device.

14. The method of claim 10, wherein the vehicle operating information includes, at least one of a vehicle speed, a fuel status, a warning indicator, and an automation systems status.
