Abstract

A deflection control apparatus is configured to perform a deflection control in which a subject vehicle is deflected by a braking force difference between left and right wheels. The deflection control apparatus is provided with a releaser configured to release the deflection control if a steering operation, which is an operation of deflecting the subject vehicle in a direction opposite to a direction in which the subject vehicle is deflected by the deflection control, is detected during the deflection control. When releasing the deflection control, the releaser is configured to reduce a controlled variable over a predetermined time, which is shorter than a fall time of the controlled variable when the deflection control is ended without being released, and which becomes longer, as the controlled variable increases when the steering operation is detected.

First claim

What is claimed is:

1. A deflection control apparatus configured to perform a deflection control in which a subject vehicle is deflected by a braking force difference between left and right wheels, said vehicle control apparatus comprising:
a processor configured to:
release the deflection control based on a steering operation, which is an operation of deflecting the subject vehicle in a direction opposite to a direction in which the subject vehicle is deflected by the deflection control, being detected during the deflection control, wherein the releasing the deflection control includes reducing a controlled variable associated with the deflection control over a predetermined time, which is shorter than a fall time of the controlled variable associated with the deflection control that is based on the deflection control ending without being released, and which becomes longer as the controlled variable increases based on the steering operation being detected.

2. The deflection control apparatus according to claim 1 , wherein the processor is further configured to set a smaller gradually decreasing slope of the controlled variable, as the controlled variable increases based on the steering operation being detected.
