摘要： PROBLEM TO BE SOLVED: To prevent the response of a liquid pressure from differing from each other in respective passages when a working liquid is supplied to a plurality of liquid pressure passages communicated with separate wheels from one liquid pressure generating source. SOLUTION: A hydraulic brake unit 20 gives a braking force to a plurality of wheels provided to a vehicle according to an operation of a brake pedal 24. A pressure-increased linear control valve 66 supplies a working liquid from an accumulator 35 to wheel cylinders of disc brake units 21FR-21RL of respective wheels. Increased-pressure holding valves 53, 54 are disposed in a flow path communicated with a rear wheel cylinder from a first passage 45a. An increased-pressure response delay restraining part opens the increased-pressure holding valves 53, 54 for a ceratin period of time from the start of liquid pressure control, so as to temporarily limit the flow of the working liquid into the wheel cylinder communicated with the first passage 45a. Thereby, a volume of the working liquid supplied to a second passage 45b is increased, so as to improve the response delay of the liquid pressure in the second passage 45b.

摘要： PROBLEM TO BE SOLVED: To obtain a sufficient negative pressure while suppressing deterioration in fuel consumption when a negative pressure for obtaining braking force is required although power from an internal combustion engine is not required during deceleration-running or the like. SOLUTION: When the power from the engine is not required but the negative pressure of a brake booster generated by the negative pressure of an engine intake system becomes insufficient, the engine alternately executes the first-third cylinders combustion cycle (410) and the second-fourth cylinders combustion cycle (420) at every 720° crank angles, wherein the first-third cylinders combustion cycle (S410) injects fuel to the first and third cylinders and does not inject the fuel to the second and fourth cylinders, and the second-fourth cylinders combustion cycle (S420) does not inject the fuel to the first and third cylinders but injects the fuel to the second-fourth cylinders. As a result, a sufficient negative pressure can be obtained in consideration of fuel consumption to thereby apply sufficient braking force. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To suppress reduction of operation feeling of a brake pedal by a driver and to simplify a structure of a hydraulic braking device. SOLUTION: A hydraulic pressure of a brake cylinder is reduced while a pressure intensifying control valve is made to the closed state when operation stroke of a brake pedal becomes constant and regeneration braking torque is increased. Since the driver frequently keep constant after the operation stroke is increased, it is not hindered even if the pressure intensifying control valve is made to the closed state. When increase of stepping is performed, increase of the operation stroke is permitted by opening/closing control of the pressure intensifying control valve. Thereby, reduction of operation feeling can be suppressed while avoiding rapid entering of the brake pedal. Thus, since reduction of the operation feeling is suppressed by control of the pressure intensifying control valve, stroke simulator is not required and since a brake cylinder hydraulic pressure is increased by a hydraulic pressure of the master cylinder, a power type hydraulic pressure source is not required.

摘要翻译：要解决的问题：为了抑制驾驶员的制动踏板的操作感觉的降低，并且简化液压制动装置的结构。解决方案：当制动踏板的操作行程变得恒定并且再生制动转矩增加时，使压力增大控制阀处于关闭状态时制动缸的液压降低。由于驾驶员在操作行程增加后经常保持恒定，所以即使增压控制阀处于关闭状态也不会妨碍。当进行踏步增加时，通过加压控制阀的打开/关闭控制允许操作行程的增加。由此，能够抑制制动踏板的快速进入的同时降低操作感觉。因此，由于通过控制加压控制阀来抑制操作感觉的降低，因此不需要行程模拟器，并且由于主缸的液压使制动缸液压升高，所以动力式液压源不是需要。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a vehicular control device capable of preventing sudden start of a vehicle while reducing the energy consumption when the braking force is controlled while the vehicle is stopped, in the vehicle in which an engine is automatically stopped when the vehicle is stopped and automatically re-started. SOLUTION: The estimated maximum driving force when an engine is re-started is acquired (S23), and the braking force to be applied to a vehicle when the engine is re-started is acquired (S26). If the operation of a starter is completed when the engine is re-started (S30), the braking force is increased if the estimated maximum driving force is larger than the braking force (S31-34). If the estimated maximum driving force is smaller than the set value, the braking force is reduced (S38). The start of the vehicle can be prevented if the maximum driving force is applied when the engine is re-started while reducing the energy consumption. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an electric parking brake device capable of rapidly suppressing the shortage of the braking force when the shortage is detected while applying an electric parking brake. SOLUTION: If the movement of a vehicle is detected (if the determination in S30 is YES) while an electric parking brake is applied (after S25-S29 are implemented if the determination in S23 is YES), or if a parking switch is operated by a driver (if the determination in S31 is YES), the application force is increased by the preset value ΔF (S32). The application force can be rapidly increased in comparison with a case in which the increase of the application force is obtained by the operation to increase the application force, and the shortage of the braking force can be suppressed. Further, since the table to be used when determining the target value of the application force is corrected (S33), occurrence of the shortage of the braking force can be avoided in the subsequent cases.
