Abstract: A vehicle controller sets an upper limit request value related to an upper limit of a longitudinal acceleration of a vehicle, a lower limit request value related to a lower limit of the longitudinal acceleration, and an acceleration request value related to the longitudinal acceleration that corresponds to an amount of the operation of the vehicle. The vehicle controller sets a first arbitration request value to a greater one of the lower limit request value and the acceleration request value. The vehicle controller sets a second arbitration request value to a smaller one of the first arbitration request value and the upper limit request value. The vehicle controller sets, to a value that corresponds to the second arbitration request value, a command value sent to an actuator that operates to adjust the traveling speed.

Abstract: A control device is applied to a vehicle that has a braking device configured to be able to adjust the braking force applied to the vehicle. The control device has a stopping braking force imparting unit that controls the braking device in order to apply a stopping braking force to the vehicle, as a minimum value of the braking force required to keep the vehicle stopped. The control device also has a deviation quantity deriving unit that derives a deviation quantity between a state quantity of the vehicle obtained when the stopping braking force is applied to the vehicle by the stopping braking force imparting unit and an ideal value of the state quantity of the vehicle. The control device also has a stopping braking force updating unit that updates the stopping braking force on the basis of the deviation quantity derived by the deviation quantity deriving unit.

Abstract: This vehicle control device is provided with: a determination unit for determining whether proscribed conditions are satisfied, including the inability to determine that a longitudinal acceleration target value is fluctuating and the ability to determine that the longitudinal acceleration of a vehicle is fluctuating; and a cooperative control unit which, on the condition that it has been determined that the prescribed conditions are satisfied, performs a braking/driving cooperative process to hold a torque output from one of a driving torque generation device and a braking torque generation device at a value which is larger than the torque at the point in time at which the prescribed conditions were met, and adjusts the torque output from the other device through feedback control using the longitudinal acceleration target value and the longitudinal acceleration of the vehicle.

Abstract: A vehicle motion controller includes a feedback controlling unit that executes feedback control in which a difference between a target acceleration corresponding to a request value from a driver assistance device and an actual acceleration of a vehicle is an input, thereby calculating a control amount used to reduce the difference, a request outputting unit that calculates a request longitudinal force based on the control amount, the request longitudinal force controlling an actuator, and an obtaining unit that obtains, as information that indicates availability, information indicating whether the at least one of the anti-lock brake control or the anti-skid control is executed, the availability being a controllable range of the longitudinal force. The feedback controlling unit keeps the control amount constant when the at least one of the anti-lock brake control or the anti-skid control is executed.
