Title: Brake fluid pressure controller for vehicle
Inventor: SOGA MASAYUKI
IPC: B60T13/66
Filed: 1999-11-19
Abstract: 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).
