Drive assist control device
First Claim
1. A drive assist control device, comprising:
- a steering determination unit that determines a steering state of a vehicle;
a curved state estimation unit that estimates a curved state of a traveling road where the vehicle is traveling;
a threshold value determination unit that, in a case where it is determined by the steering determination unit that a steering occurs after a steering wheel stationary state, sets a determination threshold value at a time of steering to be a value larger than a determination threshold value set based on a curved state estimated at the time of steering, based on the curved state estimated during a period from the time of steering to the set time after the time of steering or a period from the set time before the time of steering to the time of steering, the estimated curved state being sharper than the curved state estimated at the time of steering; and
a warning control unit that actuates a warning in a case where the steering speed at the time of steering exceeds the determination threshold value.

Abstract
A drive assist control device includes a steering determination unit 21 that determines a steering state of a vehicle, a curved state estimation unit 22 that estimates a curved state of a traveling road where the vehicle is traveling, a threshold value setting unit 23 that, in a case where it is determined by the steering determination unit 21 that a steering occurs after a steering wheel stationary state, sets a determination threshold value at the time of steering ts based on the curved state estimated during a period ts to ts+Tc from the time of steering ts to the set time Tc after the time of steering ts or a period ts−Tc to ts from the set time Tc before the time of steering ts to the time of steering ts and which is sharper than the curved state estimated at the time of steering ts, and a warning control unit 25 that actuates a warning in a case where the steering speed at the time of steering ts exceeds the determination threshold value.
