System and method for improving vehicle operator driving assistance of automotive vehicle
First Claim
1. A system for improving vehicle operator driving assistance of an automotive vehicle, the system comprising:
- a surrounding vehicle sensor that detects other surrounding vehicle conditions;
a host vehicle condition sensor that detects the host vehicle own conditions;
a lane sensor that detects positions and numbers of forward lanes;
a surrounding vehicle motion predictor that predicts future movement of the surrounding vehicle;
an evaluation function calculator that calculates a desirableness of a vehicle operator'"'"'s driving operation;
a recommended operation indicator that indicates acceleration timing and magnitude and a lane change timing with a desirable lane for the host vehicle from outputs of the surrounding vehicle motion predictor and the evaluation function calculator;
wherein the recommended operation indicator calculates a lane change necessity and produces a lane change trigger signal while the host vehicle is operated on a road that has at least three lanes; and
wherein the recommended operation indicator also prohibits to indicate a new lane change trigger signal until a forward lane change operation is deemed to be completed.

Abstract
In system and method for improving operator driving assistance of an automotive vehicle, at an indication of acceleration timing and magnitude and the lane change timing, a lane change necessity is calculated and a lane change trigger signal is produced while the host vehicle is operated on a road that has at least three lanes and, at the calculation of the lane change necessity and at the production of the lane change signal, a new lane change trigger signal is prohibited to indicate until a forward lane change operation is deemed to be completed, in a case where the vehicle is traveling on a multiple number traffic lane road.
