Abstract
Disclosed herein is a vehicle control method for collision avoidance or impact force reduction. The method may include: initiating steering control, differential braking control, or differential acceleration control of a subject vehicle depending on a yaw rate value after a collision with a following vehicle; and stopping the control depending on the yaw rate value after execution of the control.
Claims9
A vehicle control method, the method comprising:
- sequentially initiating steering control, differential braking control, and differential acceleration control of a subject vehicle depending on a yaw rate value in response to a collision with a following vehicle behind the subject vehicle causing a turning force on the subject vehicle;
- wherein the differential braking control is performed until the yaw rate value is more than or equal to a threshold in a direction in which the subject vehicle intends to be controlled after the steering control of the subject vehicle,
- wherein the differential acceleration control is performed until a variation in the yaw rate value is more than or equal to a threshold after the differential braking control of the subject vehicle, and
- wherein a steering angle of the steering control, a braking pressure of the differential braking control and an acceleration of the differential acceleration control is determined based on a difference between a current orientation angle and an orientation angle before the collision.

A vehicle control apparatus, the apparatus comprising:
- a sensor configured to sense a yaw rate value and detect a collision with a following vehicle behind a subject vehicle;
- and
- a controller configured to:
- sequentially initiate steering control, differential braking control, and differential acceleration control of the subject vehicle depending on the yaw rate value in response to the collision with the following vehicle causing a turning force on the subject vehicle,
- wherein the differential braking control is performed until the yaw rate value is more than or equal to a threshold in a direction in which the subject vehicle intends to be controlled after the steering control of the subject vehicle,
- wherein the differential acceleration control is performed until a variation in the yaw rate value is more than or equal to a threshold after the differential braking control of the subject vehicle, and
- wherein a steering angle of the steering control, a braking pressure of the differential braking control and an acceleration of the differential acceleration control is determined based on a difference between a current orientation angle and an orientation angle before the collision.
