Abstract
Described embodiments include a system and a method. A system includes a surface evaluation circuit configured to determine a surface fraction characteristic of at least a portion of a driving surface of a possible collision avoidance path of a vehicle. The system includes a rating circuit configured to assign a risk value to the possible collision avoidance path responsive to the determined surface traction characteristic. The system includes a selector circuit having a rule-set configured to select a collision avoidance path from at least two possible collision avoidance paths in response to an evaluation of the respective assigned risk value for each of the at least two possible collision avoidance paths.

36. A method comprising:
-
determining a characteristic of a first adverse circumstance present in a first possible collision avoidance path of a vehicle; assigning a first risk value to the first possible collision avoidance path responsive to the determined characteristic of the first adverse circumstance; assigning a first uncertainty to the first risk value; determining if the first risk value of the first possible collision avoidance path and the first uncertainty in a combination meet a threshold criteria; and outputting the first possible collision avoidance path as a selected collision avoidance path if the threshold criteria is met. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)

58. A method comprising:
-
determining a characteristic of a first adverse circumstance present in a first possible collision avoidance path of a vehicle; assigning a first risk value to the first possible collision avoidance path responsive to the determined characteristic of the first adverse circumstance; assigning a first uncertainty to the first risk value; determining a characteristic of a second adverse circumstance present in a second possible collision avoidance path of the vehicle; assigning a second risk value to the second possible collision avoidance path responsive to the determined characteristic of the second adverse circumstance; assigning a second uncertainty to the second risk value; establishing a threshold criteria responsive to a combination of the second risk value of the second possible collision avoidance path and the second uncertainty; determining if the first risk value of the first possible collision avoidance path and the first uncertainty in a combination meets the threshold criteria; and outputting the first possible collision avoidance path as a selected collision avoidance path if the threshold criteria is met. - View Dependent Claims (59)
