Abstract: A behavior control apparatus for a vehicle having a control unit for controlling a braking device and controlling a behavior of a vehicle by controlling braking forces of wheels. When the vehicle is in the non-braking state, the control unit acquires information on a lateral acceleration of the vehicle; calculates, based on the lateral acceleration of the vehicle, a target yaw moment of a feedforward control for reducing a rate of decrease of the vehicle's yaw gain accompanying with an increase in an absolute value of a lateral acceleration of the vehicle, and controls braking forces of the wheels by controlling the braking device so that at least a yaw moment corresponding to the target yaw moment is applied to the vehicle.

Abstract: To suppress a sharp variation in the posture of a vehicle in a control apparatus that is configured to control the posture of the vehicle by adjusting a distribution ratio of a braking force between the front and rear during braking of the vehicle.
The control apparatus includes a distribution setting unit that is configured to change the braking force distribution ratio from a basic braking force ratio during braking of the vehicle so that a posture of the vehicle follows a posture indicated by the target posture value. If the target posture value is varied when the braking force distribution ratio is different from the basic braking force ratio, the distribution setting unit sets the amount of change, by which the braking force distribution ratio is changed per unit time, equal to or smaller than a restriction amount.

Abstract: A controller for a vehicle is configured to execute a process that detects an anomaly of a steering device and a process that performs an automatic turning control that causes the vehicle to turn automatically along a traveling route. The controller is configured to perform the automatic turning control by controlling the steering device when an anomaly of the steering device is not detected. The controller is configured to, when an anomaly of the steering device is detected, calculate, as a predicted value, a load on the substitute device on an assumption that the automatic turning control is performed by activating the substitute device, and perform the automatic turning control by controlling the substitute device when an allowable range that is a set of values of a load allowable to the substitute device includes the predicted value.

Abstract: A traveling control apparatus includes an operation amount calculating unit for calculating the amount of operations for controlling at least one of a driving mechanism and a braking mechanism of a vehicle to make the difference between a target position and the actual position of the vehicle small; a determining unit for determining whether the actual position follows the target position; and a target position setting unit for setting the target position that changes with time passage, when it is determined by the determining unit that the actual position follows the target position. The target position setting unit sets the target position so a change in the target position with the time passage becomes smaller than that in the case where it is determined that the actual position follows the target position, when it is determined by the determining unit that the actual position does not follow the target position.

Abstract: A travel control device includes a turning control unit configured to execute turning support control causing a turning state quantity to follow a target turning state quantity by causing at least one of a front wheel steered angle adjustment device, a rear wheel steered angle adjustment device, and a braking device to be driven, and a steering instruction unit configured to, when steering is not being performed during the execution of turning support control, derive a holding torque and instruct a steering device to apply the holding torque to a steering wheel. The turning control unit causes the rear wheel steered angle adjustment device and/or the braking device to be driven but causes the front wheel steered angle adjustment device not to be driven when steering is not being performed. The turning control unit causes the front wheel steered angle adjustment device to be driven when steering is being performed.

Abstract: Braking torque is automatically applied based on requested deceleration and requested distance from a driving assistance device. Standard deceleration decreases in an “upwardly curved” form and then decreases in a “downwardly curved” form over time in a standard deceleration profile, and a standard speed profile corresponds to the standard deceleration profile. In the present calculation period, target deceleration and target speed profiles are set by adjusting the standard deceleration/standard speed profiles to satisfy the relationship between deceleration and vehicle body speed. The estimated distance from the reference speed to the vehicle stop is calculated based on the target speed profile. In a condition that the estimated distance is equal to/less than the requested distance is denied, braking torque is adjusted based on requested deceleration. After first satisfying the condition that the estimated distance is equal to/less than the requested distance, braking torque is adjusted according to the target deceleration profile.
