VEHICLE BRAKING ASSIST DEVICE AND VEHICLE BRAKING ASSIST METHOD
First Claim
1. A vehicle braking assist device for a host vehicle comprising:
- a risk potential computing part that computes a risk potential of the host vehicle with respect to an obstacle in the travelling direction of the host vehicle;
an accelerator operation state sensor that detects the operation state of an accelerator;
a braking force application device that applies a first braking force on the host vehicle when the risk potential is higher than a predetermined first threshold and the detected operation state of the accelerator indicates that the accelerator is not being operated, and that applies a second braking force on the host vehicle irrespective of the operation state of the accelerator when the risk potential is higher than a predetermined second threshold, wherein the risk potential represented by the second threshold is higher than the risk potential represented by the first threshold.

16. A method of assisting vehicle braking of a host vehicle comprising:
-
detecting a risk potential of the host vehicle with respect to an obstacle in a travelling direction of the host vehicle; detecting an operating state of accelerator of the host vehicle; applying a first braking force on the host vehicle when the risk potential of the host vehicle with respect to the obstacle in the travelling direction of the host vehicle is higher than a first threshold and the operating state of the accelerator indicates the accelerator is not being operated; and applying a second braking force on the host vehicle when the risk potential of the host vehicle with respect to the obstacle in the travelling direction of the host vehicle is higher than a second threshold that is higher than the first threshold, irrespective of the operation state of the accelerator.
