1. A vehicle drive assistance system, comprising a processor configured to execute:
- a required driving ability estimating module to estimate, as a required driving ability estimated value, a driver'"'"'s required driving ability required for driving a vehicle based on a traffic environment around the vehicle and drive assistance provided to the driver by the vehicle;
a current driving ability estimating module to estimate, as a current driving ability estimated value, a driver'"'"'s current driving ability based on drive history data of the vehicle and at least one of a physical state of the driver and a mental state of the driver; and
a changing module to perform increase processing in which the required driving ability estimated value is increased when the current driving ability estimated value is higher than the required driving ability estimated value, whereinthe required driving ability estimating module calculates an evaluation value of a traffic environment factor (Dt) of the traffic environment around the vehicle based on information from predetermined sensors, calculates an evaluation value of a drive assistance factor (Da) for the driver based on information regarding drive assistance, and estimates the required driving ability estimated value as a difference between the evaluation value of the drive assistance factor (Da) and the evaluation value of the traffic environment factor (Dt); and
the current driving ability estimating module calculates an estimated value of a driving skill factor (Ps) of the driver based on the drive history data of the vehicle, calculates at least one of an analytic value of a physical factor (Pp) and an analytic value of a mental factor (Pm) of the driver based on information from predetermined sensors configured to detect and/or analyze at least one of the physical state of the driver and the mental state of the driver, and estimates the current driving ability estimated value as a difference between the estimated value of the driving skill factor (Ps) of the driver and at least one of the analytic value of the physical factor (Pp) and the analytic value of the mental factor (Pm).

Abstract
A vehicle drive assistance system is provided, which includes a processor configured to execute a required driving ability estimating module to estimate a driver'"'"'s required driving ability required for driving a vehicle based on a traffic environment around the vehicle and drive assistance provided to the driver by the vehicle, a current driving ability estimating module to estimate a driver'"'"'s current driving ability, and a changing module to perform increase processing in which the required driving ability is increased when the current driving ability is higher than the required driving ability.

9. A vehicle drive assistance method that is implemented by a vehicle drive assistance system, comprising:
-
estimating, as a required driving ability estimated value, a driver'"'"'s required driving ability required for driving a vehicle based on a traffic environment around the vehicle and drive assistance provided to the driver by the vehicle; estimating, as a current driving ability estimated value, a driver'"'"'s current driving ability based on drive history data of the vehicle and at least one of a physical state of the driver and a mental state of the driver; and performing increase processing in which the required driving ability estimated value is increased when the current driving ability estimated value is higher than the required driving ability estimated value, wherein estimating the required driving ability estimated value includes calculating an evaluation value of a traffic environment factor (Dt) of the traffic environment around the vehicle based on information from predetermined sensors, calculating an evaluation value of a drive assistance factor (Da) for the driver based on information regarding drive assistance, and estimating the required driving ability estimated value as a difference between the evaluation value of the drive assistance factor (Da) and the evaluation value of the traffic environment factor (Dt); and estimating the current driving ability estimated value includes calculating an estimated value of a driving skill factor (Ps) of the driver based on the drive history data of the vehicle, calculating at least one of an analytic value of a physical factor (Pp) and an analytic value of a mental factor (Pm) of the driver based on information from predetermined sensors configured to detect and/or analyze at least one of the physical state of the driver and the mental state of the driver, and estimating the current driving ability estimated value as a difference between the estimated value of the driving skill factor (Ps) of the driver and at least one of the analytic value of the physical factor (Pp) and the analytic value of the mental factor (Pm). - View Dependent Claims (10)
