Abstract: A vehicle includes a sideslip preventing function of preventing a sideslip of the vehicle by separately adjusting a longitudinal force applied to each of the wheels. A controller controls the vehicle based on requests input from a driver assistance device, thereby causing the vehicle to travel autonomously. The controller calculates wheel lateral force request values based on the requests input from the driver assistance device. The wheel lateral force request values are request values of lateral forces acting on the respective wheels. The controller, when a behavior of the vehicle is in an oversteer state in a case in which the sideslip preventing function is failing, limits the wheel lateral force request values for the front wheels to values less than or equal to a first lateral force limit value, which is a limit value of the lateral force that can act on the rear wheels.

Abstract: A controller computes availability of the vehicle that indicates a range reachable by the vehicle by actuation of the actuator and generates a first travel route within a range of the availability of the vehicle, as a travel route followed by the vehicle, when the vehicle travels along a road ahead of the vehicle from a present position. When the road includes a curve and the first travel route cannot be generated within the availability range, the controller sets a target position to a position in the road located before the curve and generates a second travel route within the availability range, as the travel route followed by the vehicle, to stop the vehicle at the target position.

Abstract: A vehicle includes vehicle devices configured to adjust a lateral movement amount of the vehicle, and a steering wheel lock mechanism. The vehicle devices include a front-wheel steering device and a remaining device that is a device other than the front-wheel steering device. When there is an anomaly in the front-wheel steering device, a vehicle control device switches a state of the steering wheel lock mechanism from a deactivated state to an activated state. The control device adjusts the amount of lateral movement of the vehicle by activating the remaining device when rotation of the steering wheel is disabled.

Abstract: A collision avoidance ECU sets a model deceleration change amount to smaller value in a state in which it is difficult to reduce the speed of a host vehicle than in a state in which it is easy to reduce the speed of the host vehicle. The collision avoidance ECU calculates a first target value by multiplying the model deceleration change amount by the elapsed time. The collision avoidance ECU obtains a subtraction value by subtracting the current reference relative deceleration from the first target value. Then, the collision avoidance ECU determines a target relative deceleration to be a greater value when the subtraction value is large than when the subtraction value is small, and carries out brake control so that the reference relative deceleration approaches the target relative deceleration.
