Abstract
Official abstract text for this publication.
A stopping control apparatus for a vehicle includes: a braking apparatus; a gear-type automatic transmission installed in a powertrain; and a control device configured to control the braking apparatus and the automatic transmission. The control device is configured to shift, after a vehicle transitions from a travel state to a stop state, a range of the automatic transmission to a P range under a state where the braking force applied to wheels is a braking force for maintaining the vehicle in the stop state, and then reduce the braking force applied to the wheels. The control device is configured to change a decrease rate of the braking force such that the decrease rate after a time point at which a predetermined period has elapsed from a start of a decrease in the braking force is less than the decrease rate before the time point.
First claim
Opening claim text (preview).
What is claimed is: 1. A stopping control apparatus for a vehicle, comprising: a braking apparatus configured to apply a braking force to wheels; a gear-type automatic transmission installed in a powertrain; and a controller configured to control the braking apparatus and the gear-type automatic transmission, the controller being configured to shift, after the vehicle transitions from a travel state to a stop state, a range of the gear-type automatic transmission to a P range under a state where the braking force applied to the wheels is a braking force for maintaining the vehicle in the stop state, and then reduce the braking force applied to the wheels, wherein the controller is configured to change a decrease rate of the braking force applied to the wheels such that the decrease rate of the braking force applied to the wheels after a time point at which a predetermined period has elapsed from a start of a decrease in the braking force applied to the wheels is less than the decrease rate of the braking force applied to the wheels before the time point. 2. The stopping control apparatus for a vehicle according to claim 1 , wherein the controller is configured to temporarily stop the decrease in the braking force applied to the wheels when the controller determines that any wheel rotates during the decrease in the braking force applied to the wheels.
