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.
Claims17
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 movements of the surrounding vehicle;
- an evaluation function calculator that calculates an accuracy 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.
A system for improving vehicle operator driving assistance of an automotive vehicle, the system comprising:
- surrounding vehicle detecting means for detecting other surrounding vehicle conditions;
- host vehicle state detecting means for detecting the host vehicle own conditions;
- lane detecting means for detecting positions and numbers of forward lanes;
- surrounding vehicle motion predicting means for predicting future movements of the surrounding vehicles;
- evaluation function calculating means for calculating an accuracy of a vehicle operator's driving operation;
- recommended operation indicating means for indicating 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 indicating means 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 indicating means also prohibits to indicate a new lane change trigger signal until a forward lane change operation is deemed to be completed.
