摘要： PROBLEM TO BE SOLVED: To prevent brake fluid pressure control from becoming unstable due to a delay in response by feedback control caused by periodical error components resulting from localized wear or the like on the surface of a brake rotor. SOLUTION: Target wheel cylinder pressure Pwt is computed based on pressure Pm in a master cylinder 40 and a pedaling stroke St (S150, 200). The deviation ΔPw of the target wheel cylinder pressure Pwt from actual wheel cylinder pressure Pw is computed (S250). Based on the deviation ΔPw, a correction value Pva is computed on each of the rotational angle θ of a wheel for every increase in a minute rotational angle Δθ (S300). In the case of high vehicle speed, the deviation ΔPw is corrected with the correction value Pva (S700, 750) and, based on the deviation ΔPw after the correction, the feedback control amount Pfb of the wheel cylinder pressure is computed (S800), and the wheel cylinder pressure Pw is controlled based on the feedback control amount Pfb (S850).

摘要： PROBLEM TO BE SOLVED: To properly and surely control the movement of a vehicle by properly controlling the braking force of each wheel even when the defect is generated on either wheel by operating a target braking control amount of each wheel on the basis of the result of the detection of a defect state detecting means by a target braking control amount operating means. SOLUTION: Whether all the wheels are in normal state or not is judged (S15), and a next step is executed (S20) when the judgement is NO. This judgement is successively executed (S20, S25, S30), and the operation (S100) for distributing the braking force for four wheels, the operation (S600) for distributing the braking force for three wheels, the operation (S700) for distributing the braking force for two wheels, and the operation (S800) for distributing the braking force in one wheel are executed when the judgement in each step is YES, whereby a target slip ratio Sai of each wheel to be controlled is operated. Then the braking pressure of each wheel is controlled by feeding back the wheel speed to adjust the slip ratio Si of each wheel to the target slip ratio Sai (S900).

摘要： PROBLEM TO BE SOLVED: To control wheel speed to an optimum value irrespective of the friction coefficient of a road surface. SOLUTION: An error err between desired slip velocity Vslt and actual slip velocity Vsl and its integrated value (z) are computed (S20) and an equivalent control input ueq is computed on the basis of the error err of the slip velocity and the actual slip velocity Vsl (S30) while a switching function σ is computed on the basis of the integrated value (z) (S40). Whether or not the sign of the switching function σ has changed within a time T1 is determined (S50), and if the result is negative, a tire generated force (f) (kb) is computed on the basis of slip rate kb to correct parameters θand β (S60), whereas if the result is affirmative, the parameters θ and β are not corrected (S70). Further, a nonlinear input unl is computed (S80) and a control input (u) is computed as the sum of the equivalent control input ueq and the nonlinear input unl (S90) and braking torque tb is controlled to equal the control input (u) (S100).

摘要： PURPOSE:To generate an alarm at proper timing without giving physical disorder to a driver. CONSTITUTION:When there is a preceding vehicle, an inter-vehicle distance HW and the speed Vx of a driver's own vehicle are detected and whether the distance HW is less than a prescribed value L0 or not is judged (100 to 106). When the distance HW is less than the prescribed value L0, a relative speed V and relative acceleration G to the preceding vehicle are computed (108), and at the time of detecting that the acceleration G is more than a prescribed value and brake operation is not executed (110, 112), an alarm is generated (114). Since the processing is executed based upon such a driver's actual deceleration operation that even if relative speed is low when relative acceleration is high, the speed is immediately decelerated by brake operation, an alarm is generated to a driver at proper timing.
