Abstract: In one mode, with a vehicle control apparatus, a vehicle control method, and a vehicle control system according to the present invention, a control command is output for operating an actuator unit mounted in a vehicle, so as to obtain a control moment including at least one of a roll moment, a pitch moment, and a yaw moment that are generated for the vehicle before a curve on a traveling road on which the vehicle runs, based on a physical quantity about a curvature ahead on the traveling road and a physical quantity about a speed of the vehicle. In this way, the passenger's sense of security when the vehicle runs on the curve may be improved.

Abstract: A vehicle control device, a vehicle control method, and a vehicle control system according to the present invention acquire a first driving area in front of a vehicle, the first driving area being included in a first target command specified by a recognition and determination unit that performs recognition and determination, output a first control command for driving the vehicle at a velocity and on a driving path that are based on a specification relating to driving of the vehicle in the first driving area, acquire a second driving area that partly overlaps the first driving area in front of the vehicle while the vehicle is running in the first driving area, the second driving area being included in a second target command specified by the recognition and determination unit, and output a second control command for driving the vehicle at a velocity and on a driving path that are based on a specification relating to driving of the vehicle in the second driving area.

Abstract: A vehicle control device, a vehicle control method, and a vehicle control system according to the present invention perform feedback control to reduce difference in lateral direction or difference in turning direction between an own vehicle and a travel target, so as to acquire a first steering angle control conunand for increasing a steering angle control amount as the velocity of the own vehicle decreases, acquire a second steering angle control command for decreasing the steering angle control amount with respect to the velocity, compared with a magnitude of the steering angle control amount with respect to the velocity obtained by the first steering angle control command, output the first steering angle control command when the velocity is greater than a predetermined threshold, and output the second steering angle control command when the velocity is equal to, or less than, the predetermined threshold.

Abstract: A vehicle control device, a vehicle control method, and a vehicle control system according to the present invention estimate, in response to a deceleration command to a vehicle, the first deceleration generated by a frictional braking force based on characteristics of deceleration with respect to a force acting on a friction pad of a frictional braking device, determine the second deceleration by subtracting the first deceleration from the deceleration command, output the first command for generating the frictional braking force based on the deceleration command, and output the second command for generating the regenerative braking force based on the second deceleration. This allows compensating for uncertainty in achieving deceleration by frictional braking, and improving the accuracy of the actual deceleration with respect to the deceleration command.

Abstract: The vehicle control device of the present invention acquires characteristics of a road condition in front of a traveling vehicle based on external information; acquires vehicle behavior control variables for controlling the behavior of the vehicle based on estimated state variables of the vehicle that are obtained based on the characteristics, and control variables concerning speed of the vehicle based on the external information; acquires trajectory tracking control variables for causing the vehicle to track the target trajectory based on the target trajectory on which the vehicle travels that are obtained based on the characteristics and the estimated state variables; and outputs the control commands for controlling the suspension device, steering device, and braking and driving device based on the vehicle behavior control variables and the trajectory tracking control variables. This improves travel stability of the vehicle on a road surface on which an irregularity such as ruts exists.
