DRIVING SUPPORT METHOD, PROGRAM, AND DRIVING SUPPORT DEVICE

摘要

A driving assistance method executed by a driving assistance device including a tri-axial accelerometer, an information presentation controller, and an information presentation section. The driving assistance method includes: a congestion warning sign information acquisition step for acquiring congestion warning sign information based on change in the acceleration; a multi-lane information acquisition step for acquiring information regarding whether or not the position of the driving assistance device is on a multiple lane travel path; a restriction information presentation step for presenting information indicating lane change restriction when the position is on the multiple lane travel path and congestion warning sign information indicates traffic flow tending toward congestion; and a non-restriction information presentation step for presenting information indicating non-restriction of lane change when the position is on the multiple lane travel path and congestion warning sign information does not indicate traffic flow tending toward congestion.

1. A driving assistance method for assisting a driver to drive a vehicle provided with an electronic device that Comprises an acceleration acquisition device that acquires information indicating a change in an acceleration of the vehicle, and an information presentation device that presents information to the driver, the information indicating that a lane change should be restricted when driving on a travel path having multiple lanes, the method comprising:
a congestion warning sign information acquisition step of, by the electronic device, acquiring congestion warning sign information based on the information indicating the change in the acceleration acquired by the acceleration ion device, the congestion warning sign information indicating whether or not a change in traffic flow tends toward congestion; a multi-lane information acquisition step of, by the electronic device, acquiring information indicating whether or not a position of the electronic device is on a travel path having multiple lanes; a restriction information presentation step of, by the information presentation device, presenting to the driver the information indicating that the lane change is restricted in cases where the position of the electronic device is on the travel path having multiple lanes and the congestion warning sign information indicates the change in traffic flow tends toward congestion; and a non-restriction information presentation step of, by the information presentation device, presenting the information indicating that lane change is not restricted in cases where the position of the electronic device is on the travel path having multiple lanes and the congestion warning sign information does not indicate that the change in traffic flow tends toward congestion.
