Apparatus and program for assisting drive of vehicle
First Claim
1. An apparatus for assisting drive of a target vehicle travelling on a road by use of a device associated with a behavior of the target vehicle, the apparatus comprising:
- a first obtaining unit that obtains a first travelling-condition parameter of the target vehicle, the first travelling-condition parameter showing one or more conditions under which the target vehicle is travelling on the road;
a second obtaining unit that obtains a second travelling-condition parameter of a preceding vehicle travelling on the road immediately ahead of the target vehicle, the second travelling-condition parameter showing one or more conditions under which the preceding vehicle is travelling on the road;
a deviation calculator that calculates a deviation between the first travelling-condition parameter and the second travelling-condition parameter;
a behavior determiner that determines a recommended behavior of the target vehicle in response to the calculated deviation; and
a controller that controls the device according to the recommended behavior.

Abstract
In an apparatus, a first obtainer obtains a first travelling-condition parameter of a target vehicle. The first travelling-condition parameter shows one or more conditions under which the target vehicle is travelling on the road. A second obtainer obtains a second travelling-condition parameter of a preceding vehicle travelling on the road immediately ahead of the target vehicle. The second travelling-condition parameter shows one or more conditions under which the preceding vehicle is travelling on the road. A deviation calculator calculates a deviation between the first and second travelling-condition parameters. A behavior determiner determines a recommended behavior of the target vehicle in response to the calculated deviation. A controller controls a device, which is associated with a behavior of the target vehicle, according to the recommended behavior.
