Vehicle braking assist device and vehicle braking assist method

摘要

When it is judged that the risk potential of a host vehicle with respect to an obstacle ahead of the host vehicle is higher than a first threshold, and accelerator is not operated, a braking force is applied on the host vehicle. In addition, when the risk potential of the host vehicle with respect to the obstacle is higher than a second threshold, with risk potential of the second threshold being higher than the risk potential of the first threshold, a braking force is applied on host vehicle MM irrespective of the operation state of the accelerator.
