ABSTRACT:
An antiskid control device including a main line system, a first oil hydraulic source generating a pressurized oil and supplying the oil to wheel cylinders through the main line system, a subline system, and a second oil hydraulic source generating a pressurized oil and supplying the oil to the wheel cylinders through the subline system. The main line system and the first oil hydraulic source are provided for a usual braking operation. The subline system and the second oil hydraulic source are provided for an antiskid control. The main line system has a cut-off valve which opens the main line system in the usual braking operation and closes the main line system in the antiskid control. The subline system has a switching valve which opens and closes the subline system according to a locking condition of the wheel during the antiskid control. The second oil hydraulic source generates a pressurized oil when a locking condition is sensed.
