Vehicle Deceleration Controller
First Claim
1. A deceleration controller for a vehicle comprising warning braking means for performing warning braking so as to issue a warning to a crew of the vehicle;
- and travel control means for decelerating the vehicle in response to a deceleration request associated with travel control of the vehicle, wherein, even when the warning braking is needed, the warning braking is not performed if the vehicle is being decelerated by the travel control means and deceleration of the vehicle is equal to or greater than a reference value.

Abstract
An object of the present invention is to reliably carry out warning braking in a situation where the warning braking is needed and a crew can recognize the warning braking, and prevent the crew from feeling an unnatural sensation due to the warning braking in a situation where the warning braking is needed but the crew cannot effectively recognize the warning braking. If an obstacle is present ahead of the vehicle, the driver does not carry out brake operation, the driver is looking aside, and the vehicle may collide with the obstacle, the maximum target deceleration Gbt2max for the warning braking is computed. If automatic travel control is not carried out or if automatic travel control is being carried out and its target deceleration Gbt4 is less than a reference value Gbt4s smaller than the maximum target deceleration Gbt2max, the warning braking is carried out. However, when the target deceleration Gbt4 for the automatic travel control is larger than the allowable reference value Gbt4s for warning braking, the warning braking is not carried out.

6. A vehicle deceleration controller comprising warning braking means for performing warning braking so as to issue a warning to a crew of a vehicle;
- and travel control means for decelerating the vehicle in response to a deceleration request associated with travel control of the vehicle, wherein the warning braking means computes a target deceleration for the warning braking and decelerates the vehicle such that deceleration of the vehicle coincides with the target deceleration, and wherein, even when the warning braking is needed, the warning braking is not performed if the vehicle is being decelerated by the travel control means and the target deceleration is equal to or less than a sum of the deceleration of the vehicle and a predetermined value.
