Vehicle driving support device and vehicle driving support method
First Claim
1. A vehicle driving support device that supports driving of a vehicle, which includes at least one of an accelerator opening sensor, a speed sensor, a steering angle sensor, brake fluid pressure sensor, ignition sensor and a steering sensor providing signals to the vehicle driving support device, the vehicle driving support device comprising:
- a controller to receiving signals from at least one of the sensors;
the controller includes;
a change amount calculation unit to calculate a first correlation value correlated to a change amount of an acceleration of the vehicle provided by the acceleration opening sensor;
a jerk calculation unit to calculate a second correlation value correlated to a jerk of the vehicle, the jerk being an acceleration change rate per unit time; and
an operation state determination unit to determine a driving operation state of the vehicle,wherein based on the first correlation value and the second correlation value, the operation state determination unit is to calculate 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 a change when the acceleration of the vehicle is changed, by using a vibration model showing a movement of the mass point in a passenger compartment, and the operation state determination unit is to determine a driving operation state of the vehicle in accordance with a determination reference in which the ratio of the kinetic energy to the change amount of the acceleration is previously set.
