Vehicle collision management responsive to traction conditions in an avoidance path
First Claim
1. A system comprising:
- a surface evaluation circuit configured to determine a surface traction characteristic of at least a portion of a driving surface of a possible collision avoidance path of a vehicle;
a rating circuit configured to assign a risk value to the possible collision avoidance path responsive to the determined surface traction characteristic; and
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.

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.
