摘要： PROBLEM TO BE SOLVED: To improve the utility of an active stabilizer provided with an actuator for changing elastic force of a stabilizer bar. SOLUTION: An operation mode of an electric motor having the actuator is switched by switching an energizing phase in an inverter to be a control power source based on at least either a vehicle traveling condition or a road surface condition. By the switching of the operation mode, the actuator can be controlled according to the actual vehicle traveling. As the operation modes, four modes of a "control mode" capable of performing an active control, a "stand-by mode" excellent in readiness of the transfer to the active control, a "brake mode" for making the actuator into a state close to lock and a "free mode" exerting no resistance force by the actuator are set. The operation mode is switched in the four modes. By making the most of the characteristic of each of the modes, the characteristic of the stabilizer can be varied widely.

摘要： PROBLEM TO BE SOLVED: To enhance practicality of a suspension system in which devices for generating force in a direction for bringing a sprung part and an unsprung part close/apart from each other depending on the force of an electro-magnetic motor so as to correspond to respective wheels. SOLUTION: The suspension system for the vehicle is constituted such that vibration generated on a vehicle body is regarded as vibration in which a plurality of vehicle body vibrations having different kinds are synthesized and a plurality of vibration attenuation controls making each of the plurality of vehicle body vibrations as an object of attenuation can be simultaneously executed. Under the circumstance (S11, 12) that strength of a vibration component of a sprung resonance frequency in vibration of the sprung part corresponding to each of four wheels is lower than a set degree, it is constituted such that vibration attenuation control corresponding to vehicle body vibration not requiring attenuation of the plurality of vibration attenuation controls is not executed (S16-28). When vibration of relatively high frequency becomes a body, approaching/leaving force that influence is sometimes given to attenuation performance relative to such vibration is restricted and deterioration of riding comfort can be suppressed.

SOLUTION: The vehicular suspension system is configured such that a damping coefficient of each of four hydraulic shock absorbers is controlled to selectively realize a first specific state where a front wheel side damping coefficient C Fr as the damping coefficient of two of the four shock absorbers for front wheels is larger than a rear wheel side damping coefficient C Rr as the damping coefficient of the rest two for rear wheels and a second specific state where the rear wheel side damping coefficient C Rr is larger than the front wheel side damping coefficient C Fr , and thereby a pitch suppression state suitable for pitch vibration suppression and a roll suppression state suitable for roll vibration suppression can be selectively realized. Thus, suppression of pitch vibration or roll vibration can be achieved while damping high frequency vibration to suppress degradation of ride quality. COPYRIGHT: (C)2010,JPO&INPIT
