Abstract:
1. A vehicle deceleration controller comprising: a braking apparatus that generates braking to decelerate a vehicle at least in response to a vehicle brake being actuated by a vehicle driver; a warning braking control unit that controls the braking apparatus to perform warning braking so as to issue a warning to a crew of the vehicle when a decision is made that the warning braking is needed; and a travel control unit that controls the braking apparatus to decelerate the vehicle in response to a deceleration request associated with automatic travel control of the vehicle in which vehicle acceleration and deceleration are controlled without the vehicle driver actuating the vehicle accelerator or brake, wherein the warning braking control unit makes a comparison between a warning braking reference value determined by the warning braking control unit and a current vehicle deceleration requested by the travel control unit and, even when a decision is made that the warning braking is needed in a situation where the vehicle driver does not actuate the vehicle brake, the warning braking control unit does not perform the warning braking if, based on the comparison, it is determined that the vehicle is being decelerated by the travel control unit and the current vehicle deceleration is equal to or greater than the warning braking reference value.
