Abstract: A vehicle which adopts a control device as a braking control device includes a sensor that acquires a rotation angle of a wheel. The control device includes a first distance calculation unit, a second distance calculation unit, and a braking control unit. The first distance calculation unit sets a braking force corresponding to a braking operation member operation amount as a reference braking force, estimates vehicle longitudinal acceleration based on the reference braking force, and calculates a braking force reference distance estimating a moving distance until the vehicle stops based on the longitudinal acceleration. The second distance calculation unit calculates a wheel reference distance estimating the vehicle moving distance based on a detection signal of the sensor and a wheel diameter. The braking control unit executes feedback control for controlling the vehicle braking force so that a difference between the braking force reference distance and the wheel reference distance decreases.

Abstract: A travel assist device includes: a creation unit configured to create a traveling profile based on a total traveling distance; and an output unit configured to output an operation amount according to a target state amount, which is a target value of a state amount indicated by the traveling profile, to at least one of a driving device and a braking device. In a state in which a vehicle travels by the driving of at least one of the above devices based on the operation amount, the creation unit re-creates a traveling profile so that the acceleration of the vehicle does not exceed a predetermined limit value if the difference between an actual value of the state amount and the target state amount is equal to or larger than a judgment difference.

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: A motion manager that is mounted on a vehicle includes a processor and a memory. The processor receives a motion request that corresponds to an application from individual applications. The processor arbitrates the received motion request. The processor generates, based on an arbitration result, an instruction value of an operation request to be output to a brake control unit. The memory stores, in advance, type information of an actuator to be controlled by the brake control unit. The processor generates the instruction value of the operation request using the type information.

Abstract: A vehicle includes a regenerative generator on a front wheel. A braking control device includes an actuator that applies a front wheel torque and a rear wheel torque, and a controller that individually adjusts the front wheel torque and the rear wheel torque. The controller is configured to determine the front wheel torque and the rear wheel torque to zero when a regenerative braking force Fg generated by the regenerative generator has not reached a maximum regenerative force Fx which is a generatable maximum value. On the other hand, the controller is configured to increase the rear wheel torque from zero before increasing the front wheel torque from zero when the regenerative braking force Fg reaches the maximum regenerative force Fx.
