Abstract: A driving support system installed on a vehicle includes a sensor detecting a vehicle state, a braking device, and a control device. The control device determines, based on the vehicle state, whether or not a first condition suggesting roll back of the vehicle is satisfied, and whether or not a second condition more strongly suggesting the roll back of the vehicle than the first condition is satisfied after the first condition is satisfied. When the second condition is satisfied after the first condition is satisfied, the control device executes roll back suppression control that controls the braking device to generate a braking force such that the vehicle stops. During a period from when the first condition is satisfied to when the second condition is satisfied, the control device executes precharge control that decreases play in the braking device without starting the roll back suppression control.

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 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 prediction unit predicts a limit time at which a limit request value corresponding to a minimum acceleration or torque is reached when a vehicle is decelerated with only a first deceleration control by a drive device based on change over time of a request value indicating a degree of longitudinal direction vehicle acceleration. A mode determination unit selects one of: a first mode in which only the first control is executed, and before the limit time is reached, in addition to the first control, a second deceleration control is started by a braking device; or a second mode in which only the first control is executed, and before the limit time is reached, in addition to the first control, a braking preparation control is started. A calculation unit calculates an operation amount of the drive and braking devices based on the request value in accordance with the determined mode.

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 traction control is executed, the availability being a controllable range of the longitudinal force, wherein the feedback controlling unit prohibits the control amount from increasing when the traction control is executed.

Abstract: A vehicle controller includes a controlling unit. The controlling unit calculates a feedback control amount based on a deviation between a target acceleration of a vehicle and an actual acceleration of the vehicle. The controlling unit executes a feedback control of a driving device and a braking device by using the feedback control amount, such that the deviation decreases. A state in which only the driving device, of the driving device and the braking device, operates is a first state. A state in which at least the braking device, of the driving device and the braking device, operates is a second state. When switched from the first state to the second state, the controlling unit calculates the feedback control amount such that the deviation permitted in the feedback control is greater than the deviation prior to a start of switching from the first state to the second state.

Abstract: A vehicle control device is configured such that if, during an automatic driving mode in which a vehicle is automatically driven regardless of operations by a driver, such automatic driving mode is temporarily stopped by a prescribed operation by the driver and a normal driving mode in which the vehicle is driven in accordance with the operations of the driver is entered, and thereafter the automatic driving mode is returned to from the normal driving mode, specific control is implemented in the post-return automatic driving mode, such control being determined on the basis of the driving state of the vehicle during the normal driving mode before the return.
