Patent ID: 7301295

Claim:
A stabilizer control device comprising: a stabilizer including: a first torsion bar and a second torsion bar provided between a first wheel and a second wheel of a vehicle; and a brushless motor provided between the first torsion bar and the second torsion bar and having an exciting coil, the brushless motor rotating in accordance with an excited state of the exciting coil; a rotating direction switching device including a first switching element group and a second switching element group, which are connected to the brushless motor, the rotating direction switching device switching a rotating direction of the brushless motor by changing a pattern in which first switching elements of the first switching element group and the second switching elements of the second switching element group are controlled so as to be in a conducting state or a non-conducting state; an excitation control device for controlling power supplied to the exciting coil; a vehicle state detecting device for detecting a vehicle state including a traveling state of the vehicle and a steering state operated by an operator; a rotating state detecting device for detecting a rotating state of the brushless motor; a roll control device for reducing a rolling movement of the vehicle by controlling a torsional force generated at the stabilizer by controlling the rotating direction switching device and the excitation control device in accordance with the rotating state detected by the rotating state detecting device and the vehicle state detected by the vehicle state detecting device; a brake mode by which all the switching elements of one of the first switching element group and the second switching element group are controlled so as to be in a conducting state, and all the switching elements of the other of the first switching element group and the second switching element group are controlled so as to be in a non-conducting state; and a brake mode executing device for executing the brake mode in accordance with the controlling state of the roll control device.
