METHOD AND SYSTEM TO ESTIMATE DRIVING RISK BASED ON A HEIRARCHICAL INDEX OF DRIVING
First Claim
1. A system for providing driving risk assessment in a host vehicle comprising:
- a hierarchical index of passive driving conditions, wherein each passive driving condition is assigned a first risk factor;
an active driving conditions identification system, wherein said active driving conditions identification system assigning a second risk factor to each of each of said active driving conditions identified; and
a processor for generating a driving risk assessment, said processor identifying each of said passive driving condition applicable to current driving conditions and refining said identified passive driving conditions with the identified active driving conditions to provide a driving risk assessment for current host vehicle operation.

Abstract
A system and method for providing driving risk assessment for a host vehicle equipped with on-board sensors or vehicle-to-vehicle or infrastructure-to-vehicle systems. The system includes a hierarchical index of passive driving conditions, a means of collecting active driving conditions and a processor whereby the sum of passive driving conditions may be further refined by the active driving conditions The method incorporates a hierarchical index of risks associated with passive driving conditions, and refining said risks with active driving conditions of the vehicle to generating a driving risk assessment for current vehicle operation.

4. A method for providing driving risk assessment to an operator of a host vehicle equipped with on-board sensors or vehicle-to-vehicle or infrastructure-to-vehicle systems, whereby said assessment may also be incorporated into an autonomously driven vehicle to provide for the safe operation thereof, said method comprising the steps of:
-
establishing a hierarchical index of passive driving conditions; assigning a first risk factor to each passive driving condition; identifying each passive driving condition related to current vehicle operations; identifying active driving conditions of the vehicle, and assigning a second risk factor to each active environmental conditions; generating a driving risk assessment for current vehicle operation based upon each of the first risk factors of the identified passive driving conditions of the hierarchical index and the active driving conditions. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)
