Document Type and Number:
Japanese Patent JP2008114843
Kind Code:
A
Abstract:
To supply a pilot oil even if trouble occurs in a steering system.
In this steering system for a vehicle, a basic steering operation device and a secondary steering operation device are combined with each other to resist a fluid flow in a valve body and these operation devices are used. If a basic steering actuator or a valve element fails, both the basic valve element and the secondary valve element are so electrically operated by a control unit that the secondary steering operation element and the valve element can supply the pilot oil to the system.
