  • Vehicle driving support device and vehicle driving support method
    Patent number: 8843272
    Abstract: There is provided a vehicle driving support device including: a change amount calculating part 10 that calculates a first correlation value correlated to a change amount of acceleration of a vehicle; a jerk calculating part 11 that calculates a second correlation value correlated to a jerk of the vehicle; and an operation state determining part 13 that determines a driving operation state of the vehicle from a first correlation value calculated by a change amount calculating part 10, and a second correlation value calculated by a jerk calculating part 11, in accordance with a determination reference previously set from a ratio of a kinetic energy of a mass point to the change amount of the acceleration of the vehicle at an end point of change when the acceleration of the vehicle is changed, calculated using a vibration model showing a movement of the mass point in a passenger compartment.
