摘要： Provided is a collision avoidance apparatus that can avoid a collision through both steering and braking. In a collision avoidance apparatus, a no-entry zone defining unit defines a no-entry zone for preventing a subject vehicle from colliding with an obstacle around the subject vehicle, based on obstacle information including information on a position of the obstacle and based on lane information that is information on a traveling lane of the subject vehicle. A following determination unit determines whether the obstacle is an avoidance target or a following target, based on the position of the obstacle or a position of the no-entry zone. A constraint establishing unit establishes a constraint on a state quantity or a control input of the subject vehicle to prevent the subject vehicle from at least entering the no-entry zone.

摘要： Provided is an obstacle avoidance apparatus that can specify a distance between a subject vehicle and an obstacle when making the subject vehicle avoid the obstacle. An obstacle avoidance apparatus includes: an obstacle movement predictor that predicts movement of the obstacle; and a constraint generator that establishes a constraint on a state quantity or a control input of the subject vehicle by determining whether to steer right or left around the obstacle and defining a no-entry zone for preventing the subject vehicle from colliding with the obstacle. The constraint generator incorporates, into the no-entry zone, an area to the left of the obstacle when determining to steer right around the obstacle, and incorporates, into the no-entry zone, an area to the right of the obstacle when determining to steer left around the obstacle.

摘要： In a vehicle control device, a switching hyperplane generation unit generates a switching hyperplane based on a travel state of a vehicle and cornering stiffness dependent on a travel surface state as a state of a road surface on which the vehicle travels. A deviation computation unit calculates a deviation between a target trajectory and an actual trajectory of the vehicle. A state estimation unit estimates a state to be controlled of the vehicle based on the deviation calculated by the deviation computation unit. A target steering angle and acceleration/deceleration computation unit calculates a target steering angle and a target acceleration/deceleration rate of the vehicle based on the switching hyperplane generated by the switching hyperplane generation unit and an estimated state as the state estimated by the state estimation unit.
