Abstract: A vehicular brake device that implements ESC/TRC control suppresses hydraulic pressure variations produced during open/close control of a brake actuator holding valve or depressurizing valve. While a brake operating member is not operated and a wheel cylinder pressure supplying control is executed to supply target wheel cylinder pressure to respective wheel cylinders, the target servo pressure is set to a first predetermined target servo pressure smaller than a maximum output pressure of the servo pressure generating device. When wheel cylinder pressure supplying control starts, the target servo pressure is set as the target wheel cylinder maximum value when a firstly occurred rising inclination of the target wheel cylinder maximum value is equal to or more than a minimum increment of an output of the servo pressure generating device per unit time and at the same time when the target wheel cylinder pressure is below the first determined target servo pressure.

Abstract: An information processing method includes receiving shift requests to control a shift range of a vehicle from a plurality of application software products configured to implement driver assistance functions of the vehicle, arbitrating the shift requests by using, as a condition, whether each of the received shift requests is a request in a traveling range or a request in a parking range, when the traveling range is the shift range in which a driving wheel of the vehicle is rotatable and the parking range is the shift range in which the driving wheel is not rotatable, and generating an instruction value for an action request to drive an actuator based on a result of arbitration.

Abstract: The present invention relates to a vehicle brake device which can secure the durability of a linear valve for controlling a servo pressure. The brake ECU of the vehicle brake device sets a reference servo pressure based on the operating amount of a brake pedal when the vehicle is stopped and sets a target servo pressure based on the reference servo pressure during one braking operation. Further, the brake ECU sets the reference servo pressure based on the operating amount of the brake pedal when the servo pressure calculated in response to the operating amount of the brake pedal exceeds the servo pressure change threshold value set with a deviation from the reference servo pressure calculated in response to the brake pedal operating amount.
