A vehicle controller includes a collision detector, a braking controller, a motional state detector, and a minor collision determiner. The collision detector is configured to detect a collision between a vehicle and another object. The braking controller is configured to cause a braking device of the vehicle to generate a braking force in accordance with the detecting of the collision by the collision detector. The motional state detector is configured to detect a motional state of the vehicle. The minor collision determiner is configured to determine, based on an output from the motional state detector, that a minor collision occurs that is a collision not detected by the collision detector. The braking controller is configured to cause the braking device to generate the braking force if the collision detector does not detect the collision and the minor collision determiner determines that the minor collision occurs.

In motion control in the present invention, operation amounts relating to braking and drive are set as a control command when a difference between a physical quantity relating to a target vehicle attitude which is based on a target trajectory and a physical quantity relating to a linear model vehicle attitude which is based on a linear model of a vehicle exceeds a threshold value, operation amounts relating to braking and steering are set as the control command when the difference is equal to or smaller than the threshold value, and an attitude of the vehicle in a yaw direction is controlled based on the control command.

A vehicle control apparatus includes a contact detector, an attitude stabilization processor, and a steering intention determining unit. The contact detector is configured to detect a contact of a vehicle with an object. The attitude stabilization processor is configured to execute an attitude stabilization control that generates a yaw moment at a vehicle body on the basis of a deviation between a target yaw rate and an actual yaw rate. The steering intention determining unit is configured to determine a presence of a driver's intention to perform steering. The attitude stabilization processor is configured to stop the generation of the yaw moment by the attitude stabilization control or reduce the yaw moment to be generated by the attitude stabilization control, in a case where the steering intention determining unit determines that the driver's intention to perform the steering is absent after the detection of the contact by the contact detector.

A method in a vehicle for estimating vehicle motion state during a vehicle maneuver, comprising; obtaining a trigger signal indicating an onset of the vehicle maneuver, selecting a sub-set of wheels on the vehicle to be in a free-rolling condition, measuring one or more parameters related to revolution of the sub-set of wheels in free-rolling condition, and estimating the vehicle motion state based on the measured parameters.
