VEHICULAR STABILIZER SYSTEM

PROBLEM TO BE SOLVED: To improve the practicability of a vehicular stabilizer system which actively controls the rigidity of a stabilizer by an actuator having an electric motor. SOLUTION: The control of one stabilizer device, forcible control in a brake mode, that is, control which enables a switching element to short-circuit each phase of a motor is carried out (S10) while control in a free mode is carried out (S9) in the other stabilizer device at that time when the control in the free mode, that is, control which enables the switching elements of an inverter that is the drive circuit of a motor to be all opened is carried out (S8) to one stabilizer device on the front wheel side or the rear wheel side in a roll moment reduction process. Electric currents generated by electric motors of both stabilizer devices are prevented from simultaneously flowing back toward a power source. COPYRIGHT: (C)2007,JPO&INPIT
