Vehicle safety running system
First Claim
1. A vehicle safety running system comprising:
- object detection means for detecting an object in front of a subject vehicle in a direction in which the subject vehicle travels;
contact probability estimation means for estimating probability in which the subject vehicle comes into contact with the detected object;
automatic braking means for automatically actuating a brake system of the subject vehicle when said contact probability estimation means estimates that there is a probability of such contact; and
steering operation amount detection means for detecting a steering operation amount based on a steering operation by a driver, wherein when said steering operation amount detection means detects that the driver performs the steering operation while said automatic braking means is in operation, said automatic braking means cancels automatic braking for a time period or at a speed determined based on at least one of the contact probability estimated by said contact probability estimation means and the steering operation amount detected by said steering operation amount detection means.

Abstract
In a vehicle safety running system, while a contact probability estimation section estimates that there is a probability that a subject vehicle comes into contact with an object and an automatic braking section performs automatic braking, when the driver voluntarily performs a steering operation to avoid the contact, an automatic braking cancellation gradient is calculated based on the contact probability detected with the contact probability estimation section and the steering operation amount detected with the steering operation amount detection section, whereby automatic braking is cancelled at a speed corresponding to the automatic braking cancellation gradient so calculated. When the contact is easily avoided through the steering operation, the automatic braking cancellation gradient is set large so as to cancel automatic braking quickly, while when the contact is difficult to be avoided, the automatic braking cancellation gradient is set small so as to cancel automatic braking moderately.
