Abstract: The vehicle control apparatus gives a control current to the electromagnetic control valve at a start of energization of the electromagnetic control valve as a start current value smaller by a first determined amount than an open/closed state change-over reference current value which is necessary for changing over a state of the electromagnetic valve and after the start of energization of the electromagnetic control valve, the control current gradually increases with a smaller increase inclination than an increase inclination of an increase control of the control current which gives priority to a control responsibility of the electromagnetic control valve and finishes a gradual increase of the control current applying to the electromagnetic control valve, when the control current exceeds a finish current value which is larger than the open/closed state change-over reference current value.

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.

Abstract: In a braking device for a vehicle, an operating characteristics setting portion is provided for setting an operating characteristic which is a relationship between the input electric power to the electro-magnetic valve and a pressure difference between a master cylinder side and a wheel cylinder side with respect to the electro-magnetic valve, based on the input electric power at the time when the accumulator pressure detected by the accumulator pressure detecting portion first falls to a value equal to or less than a threshold value accumulator pressure by changing the input electric power towards an opening side of the electro-magnetic valve in response to a time lapsed after a predetermined value of the pilot pressure has been generated by the pilot pressure generating portion by first closing the electro-magnetic valve thereby to suppress the manufacturing cost.

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.
