Abstract: A vehicle brake hydraulic pressure control apparatus includes a wheel speed acquiring section, a vehicle body deceleration calculator, and a switch section. The wheel speed acquiring section is configured to acquire a wheel speed from a wheel speed sensor. The vehicle body deceleration calculator is configured to calculate a vehicle body deceleration. The switch section is configured to switch control from the regenerative cooperation control to the hydraulic pressure control, based on (i) a wheel deceleration which is determined based on the wheel speed and (ii) the vehicle body deceleration. The vehicle body deceleration calculator is configured to calculate the vehicle body deceleration based on a required deceleration which corresponds to a driver's operation of a braking pedal.

Abstract: One embodiment provides a vehicle brake hydraulic controller including a wheel speed acquiring section; a wheel deceleration calculator; a vehicle velocity calculator; and a locking tendency determination section. The vehicle velocity calculator calculates a vehicle deceleration based on a temporary vehicle deceleration corresponding to an acceleration sensor value and calculates a vehicle velocity based on the calculated vehicle deceleration. The vehicle velocity calculator calculates the temporary vehicle deceleration by offsetting a first correction amount to a deceleration side in relation to the acceleration sensor value. When a brake pedal operation amount by a driver is equal to or smaller than a first threshold and that an absolute value of the wheel deceleration is equal to or larger than an absolute value of a second threshold are met, the first correction amount is set to be smaller than when the conditions are not met.

Abstract: A prepainted steel sheet has a chemically conversion-treated zinc-plated steel sheet and a coating formed on the surface of said zinc-plated steel sheet. The coating is formed by painting and baking of a solvent-type-paint composition. The paint composition contains a polyester resin.

Abstract: An organic composite coated steel sheet having excellent chromate dissolution resistance, wet adhesion, and corrosion resistance before and after working. The steel sheet comprises a chromate-silica film on at least one face of a zinc or zinc base alloy plated steel sheet, the silica-added chromate film having about 5 to 500 mg/m.sup.2 in terms of metal Cr content and being formed from a chromate solution containing about 25 to 70 wt % of Cr.sup.+6 based upon total Cr content. A resin coating film is adhered to the chromate-silica film and is formed from an aqueous paint. The aqueous paint includes an aqueous anionic resin and/or an aqueous nonionic resin, a reducing agent, and a water-dispersed silica. The resin coating film is deposited in a dry weight amount of about 0.1 to 3 g/m.sup.2.
