Abstract

A method of alerting a driver of a vehicle is provided. The method includes: receiving conditions data from one or more collision avoidance systems; determining an alert mode based on the conditions data, wherein the alert mode indicates at least two of alert conditions, vehicle conditions, and driving scenarios; and at least one of arbitrating, synchronizing, and combining at least two alert patterns associated with the at least two of the alert conditions, the vehicle conditions, and the driving scenarios and associated with one or more alert devices.

First claim

What is claimed is:

1. A method of alerting a driver of a vehicle, comprising:
receiving, by a control unit, conditions data from one or more collision avoidance systems;
determining, by the control unit, an alert mode based on the conditions data, wherein the alert mode indicates at least two of user configured alert conditions, vehicle conditions, and driving scenarios;
identifying at least two alert patterns associated with the at least two of user configured alert conditions, vehicle conditions, and driving scenarios; and
coordinating a generation of at least one alert pattern signal from the at least two alert patterns by at least one of arbitrating, synchronizing, and combining the at least two alert patterns based on whether the at least two alert patterns are associated with a same alert device or different alert devices,
wherein if the at least two alert patterns are associated with the same alert device only, combining or arbitrating the at least two alert patterns for the same alert device to generate said at least one alert pattern signal,
if the at least two alert patterns are associated with said different alert devices only, synchronizing the at least two alert patterns between the different alert devices to generate said at least one alert pattern signal, and
if, in addition to the at least two alert patterns being associated with the same alert device, the at least two alert patterns are associated with the different alert devices, combining or arbitrating the at least two alert patterns for the same alert device, and synchronizing the at least two alert patterns between the different alert devices, to generate said at least one alert pattern signal.

2. The method of claim 1 , wherein the same alert device and the different alert devices comprise from a group including one or more of a haptic alert device, one or more of an auditory alert device, and one or more of a visual alert device.

3. The method of claim 1 , wherein the arbitrating the at least two alert patterns comprises arbitrating based on a predefined priority scheme to determine a preferred pattern.

4. The method of claim 1 , wherein the combining the at least two alert patterns comprises at least one of summing and superimposing the at least two alert patterns.

5. The method of claim 1 , wherein the receiving the conditions data is from at least one of a line-of-sight collision avoidance system and a non-line-of-sight collision avoidance system.

6. A control system for alerting a driver of a vehicle comprising:
a first module that receives conditions data from one or more collision avoidance systems, and that determines an alert mode based on the conditions data, wherein the alert mode indicates at least two of user configured alert conditions, vehicle conditions, and driving scenarios; and
a second module that identifies at least two alert patterns associated with the at least two of user configured alert conditions, vehicle conditions, and driving scenarios, that coordinates a generation of at least one alert pattern signal from the at least two alert patterns by at least one of arbitrating, synchronizing, and combining the at least two alert patterns based on whether the at least two alert patterns are associated with a same alert device or different alert devices wherein if the at least two alert patterns are associated with the same alert device only, combining or arbitrating the at least two alert patterns for the same alert device to generate the at least one alert pattern signal, and
if the at least two alert patterns are associated with said different alert devices only, combining or arbitrating the at least two alert patterns between the different alert devices to generate the at least one alert pattern signal, and
if, in addition to the at least two patterns being associated with the same alert device, the at least two alert patterns are associated with the different alert devices, combining or arbitrating the at least two alert patterns for the same alert device, and synchronizing the at least two alert patterns between the different alert devices to generate the at least one alert pattern signal.

7. The control system of claim 6 , wherein the same alert device and the different alert devices comprise from a group including one or more of a haptic alert device, one or more of an auditory alert device, and one or more of a visual alert device.

8. The control system of claim 6 , wherein the second module arbitrates the at least two alerts patterns based on a predefined priority scheme to determine a preferred pattern.

9. The control system of claim 6 , wherein the second module combines the at least two alert patterns by a t least one of summing and superimposing the at least alert patterns.

10. The control system of claim 6 , wherein the conditions data is received from at least one of a line-of-sight collision avoidance system and a non-line-of-sight collision avoidance system.
