Abstract: A braking control device includes a master unit including a master chamber connected to a front wheel cylinder and a servo chamber that applies forward force opposing a reverse force applied to a master piston by the master chamber to the master piston, a pressure adjustment unit that adjusts brake fluid discharged by a pump to a first liquid pressure by a first solenoid valve and introduces the first liquid pressure to a rear wheel cylinder, and adjusts the first liquid pressure to decrease to a second liquid pressure by a second solenoid valve and introduces the second liquid pressure to the servo chamber; and a regenerative coordination unit having an input piston operable in conjunction with a braking operation member and an input cylinder fixed to the master cylinder, and in which a gap between the master piston and the input piston is controlled by the second liquid pressure.

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.

Abstract: Provided is a control device for a vehicle including an operation amount calculation unit for calculating, in a first travel mode using an automatic control that is not dependent on a driving operation by a driver, an operation amount for controlling a drive device and/or a braking device on a basis of a travel resistance value and a request value indicative of a level of acceleration of the vehicle; a correction value calculation unit for calculating, in a second travel mode based on the driving operation by the driver, a correction value corresponding to an error of the travel resistance from a drive output value, a travel resistance value, and an acceleration value obtained in a state where a predetermined condition is fulfilled; and a travel resistance value correction unit for correcting the travel resistance value with the correction value.

Abstract: A hydraulic circuit comprises: a first pressure-boosting flow path that connects a first main flow path and a first wheel cylinder; a first pressure-boosting valve that is disposed in the first pressure-boosting flow path and that opens in a non-energized state; a first pressure-reducing flow path that connects the first wheel cylinder and a reservoir; a first pressure-reducing valve that is disposed in the first pressure-reducing flow path and that closes in a non-energized state; a second pressure-boosting flow path; a second pressure-boosting valve; a second pressure-reducing flow path; and a second pressure-reducing valve. A control unit comprises: a first drive circuit that controls the first pressure-reducing valve; and a second drive circuit that is separate from the first drive circuit and that controls the second pressure-reducing valve.

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 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.
