Abstract
A driving assistance control apparatus includes an own-vehicle position acquiring unit that acquires the position of an own vehicle; a curve information acquiring unit that acquires curve information on a driving course; a continuous curves detecting unit that detects a first curve ahead of the own vehicle and a second curve that exists at a far side of the own vehicle with respect to the first curve and that is continuous to the first curve, based on the acquired position of the own vehicle and the acquired curve information; and a curve alert control unit that controls a curve alerting unit that alerts the presence of the second curve before an entrance of the second curve. The curve alert control unit sets the alert timing of the second curve in accordance with the curve information about the first curve.
Claims13
A driving assistance control apparatus comprising:
- an own-vehicle position acquiring unit acquiring a current position of an own vehicle;
- a curve information acquiring unit acquiring curve information on a driving course;
- a continuous curves detecting unit detecting continuous curves including a first curve existing ahead of the own vehicle and a second curve existing ahead of and continuous to the first curve, the continuous curves detecting unit detecting the continuous curves using the position of the own vehicle acquired by the own-vehicle position acquiring unit and the curve information acquired by the curve information acquiring unit;
- and
- a curve alert control unit controlling a curve alerting unit alerting the presence of the first curve, and alerting the presence of the second curve before entering the second curve, the curve alerting unit alerting by using one of alerting methods consisting of a temporary change in the number of revolutions of an engine or a traction motor, applying temporary automatic braking, outputting a warning tone from a speaker, displaying a warning, a temporary change in a pedal reaction force against an acceleration pedal, and applying temporary vibration to a steering wheel,
- wherein the curve alert control unit sets an alert timing of the presence of the second curve in accordance with the curve information about the first curve, wherein the curve alert control unit advances the alert timing of the presence of the second curve with the increasing degree of curve of the first curve,
- wherein the curve alert control unit sets a first alert start position at which alerting of the presence of the first curve is started, the first alert start position being set to a position before an entrance of the first curve,
- wherein the curve alert control unit obtains a second alert start position corresponding to the alert timing of the presence of the second curve, separately from the first alert start position,
- wherein the curve alert control unit performs a first determination of whether a radius of the first curve is smaller than that of the second curve or whether a curvature of the first curve is higher than that of the second curve, and if the first determination is affirmative, does not alert the presence of the second curve.
A driving assistance control method comprising:
- a) acquiring a position of an own vehicle;
- b) acquiring curve information on a driving course;
- c) detecting, using a processor, continuous curves including a first curve existing ahead of the own vehicle and a second curve existing ahead of and continuous to the first curve, by using the position of the own vehicle acquired by the step a) and the curve information acquired by the step b);
- and
- d) setting, using a processor, a first alert start position at which alerting of the presence of the first curve is started, the first alert start position being set to a position before an entrance of the first curve;
- e) alerting, using a processor, the presence of the second curve before entering the second curve at an alerting timing by using one of alerting methods consisting of a temporary change in the number of revolutions of an engine or a traction motor, applying temporary automatic braking, outputting a warning tone from a speaker, displaying a warning, a temporary change in a pedal reaction force against an acceleration pedal, and applying temporary vibration to a steering wheel, wherein the alert timing of the presence of the second curve is set in accordance with the curve information about the first curve such that the alert timing of the presence of the second curve is advanced with the increasing degree of curve of the first curve,
- wherein the step e) obtains a second alert start position corresponding to the alert timing of the presence of the second curve, determines whether the second alert start position is located within the first curve, and if so, changes the second alert start position to a position before the entrance of the first curve.
