The modified polyolefin resin layer provided between the transparent polyester resin film and the metal sheet has excellent adhesiveness against the decorative layer, the paint layer and the polyesters resin film so that delamination of the resin-coated metal sheet does not occur even in the case in which the resin-coated metal sheet is formed under severe conditions such as deep drawing. The modified polyolefin layer absorbs any unevenness of the component layers so that the resin-coated metal sheet exhibits excellent reflectivity.

    Abstract: An anti-lock control method for a vehicle includes the steps of: calculating an operation control quantity on the basis of a braking pressure at the start of an anti-lock control when a wheel is about to be locked during braking, and controlling the operation of an actuator, capable of adjusting the braking force of a wheel brake by the operation control quantity in order to reduce the braking force. In this process, the braking pressure at the start of anti-lock control is corrected with the locking tendency of the wheel to set an adjusted reference braking pressure, and the operation control quantity is calculated on the basis of the adjusted reference braking pressure. Thus, it is possible to determine the reference braking pressure with good accuracy, leading to an enhanced accuracy of the anti-lock control.
