Brake control device for a vehicle

A brake control device for a vehicle comprising:

• a brake operating member;
• hydraulic pressure generating means for generating a master cylinder hydraulic pressure in a master cylinder in response to an operating force-applied to said brake operating member;
• a plurality of wheels;
• a plurality of wheel brake cylinders each mounted on a respective one of wheels;
• a pressure chamber defined in said master cylinder;
• pressure increasing means for introducing a servo pressure into said pressure chamber to increase said master cylinder hydraulic pressure with said servo pressure;
• automatic pressure increasing control means for controlling said servo pressure introduced to said pressure chamber by said pressure increasing means and for controlling a pressure increase amount of said master cylinder hydraulic pressure;
• braking force control means for controlling the hydraulic pressure applied to each wheel brake cylinder using said master cylinder hydraulic pressure;
• servo pressure memorizing means for memorizing said servo pressure controlled by said-automatic pressure increasing control means when an anti-skid control begins to be applied to all of said wheels by said braking force control means;
• vehicle deceleration change detecting means for detecting a vehicle deceleration change occurring after said anti-skid control begins to be applied to all vehicle wheels;
• servo pressure correcting means for correcting said memorized servo pressure on the basis of said vehicle deceleration change detected by said vehicle deceleration change detecting means;
• and
• said automatic pressure increasing control means employing said corrected servo pressure as an upper limit of said servo pressure and controls said pressure increase amount of said master cylinder hydraulic pressure while said anti-skid control is being applied to said all of the wheels.
