Abstract

A method of providing inertia drive information to perform inertia driving of a vehicle may include recognizing a target position, where deceleration is required from a current speed of the vehicle, as an inertia drive event on a driving route at which a destination is set by a navigation function, when a plurality of inertia drive events are recognized in the recognizing of the target position as the inertia drive event, determining a predetermined priority with respect to each of the plurality of inertia drive events, determining an inertia drive start position required to reach, at a target speed, a target position of an inertia drive event having a high priority, which is determined by the determining of the predetermined priority, among the plurality of inertia drive events, and providing information on an inertia drive start position through a method which is recognizable by a driver.

1. A method of providing inertia drive information to perform inertia driving of a vehicle, comprising the steps of:

recognizing a target position, where deceleration is required from a current speed of the vehicle, as an inertia drive event on a driving route at which a destination is set by a navigation function;

when a plurality of inertia drive events are recognized in the step of recognizing the target position as the inertia drive event, determining a predetermined priority with respect to each of the plurality of inertia drive events;

determining an inertia drive start position required to reach, at a target speed, a target position of an inertia drive event having a high priority, which is determined by the step of determining the predetermined priority, among the plurality of inertia drive events; and

providing information on an inertia drive start position through a method which is recognizable by a driver.

2. The method of claim 1, further comprising the steps of:

determining whether the vehicle passes an inertia drive event, which is first upcoming, among the plurality of inertia drive events; and

when the vehicle is determined as passing the inertia drive event that is first upcoming, updating information on the inertia drive event.

3. The method of claim 2, wherein:

the step of recognizing the target position as the inertia drive event is performed with respect to target positions within a front data acquisition effective distance of the vehicle; and

when the vehicle is determined as not passing the inertia drive event that is first upcoming even though a new target position occurs within the front data acquisition effective distance, the recognizing of the target position as the inertia drive event does not recognize the new target position as the inertia drive event.

4. A method of providing inertia drive information to perform inertia driving of a vehicle, comprising the steps of:

recognizing a target position, where deceleration is required from a current speed of the vehicle, as an inertia drive event on a driving route at which a destination is set by a navigation function;

when a plurality of inertia drive events are recognized in the step of recognizing the target position as the inertia drive event, determining an upcoming time to a target position with respect to each of the plurality of inertia drive events;

determining an inertia drive start position required to reach, at a target speed, a target position of an inertia drive event that is first upcoming, which is determined by the step of determining the upcoming time, among the plurality of inertia drive events; and

recognizing a target position, where deceleration is required from a current speed of the vehicle, as an inertia drive event on a driving route at which a destination is set by a navigation function;

when a plurality of inertia drive events are recognized in the step of recognizing the target position as the inertia drive event, comparing a target speed C of an inertia drive event that is first upcoming with a target speed D of an inertia drive event that is upcoming later among the plurality of inertia drive events;

when the target speed C of the inertia drive event that is first upcoming is greater than the target speed D of the inertia drive event that is upcoming later, comparing the target speed D with a preset minimum value Cmin of the target speed C of the inertia drive event that is first upcoming;

determining an inertia drive start position required to reach, with a large value of the preset minimum value Cmin or the target speed D, a target position of the inertia drive event that is first upcoming; and
