摘要： PROBLEM TO BE SOLVED: To more accurately estimate the state of a suspension.
SOLUTION: The vehicular suspension control device 1A includes: a vehicle behavior prediction part 201; a vehicle behavior estimation part 202; and a suspension control part 203. The vehicle behavior prediction part 201 predicts a vehicle behavior with respect to disturbance (road surface profile) added to the vehicle in the future. The vehicle behavior estimation part 202 corrects a gain of a Kalman filter used for estimating the vehicle behavior in the future based on the prediction result of the vehicle behavior in the future. The vehicle behavior estimation part 202 estimates the present vehicle behavior using the Kalman filter which has been corrected in gain. The suspension control part 203 controls the movement of the active suspension device based on the estimation result.

摘要： PROBLEM TO BE SOLVED: To more certainly suppress one side flow of a vehicle.
SOLUTION: When it is determined that the vehicle linearly travels (step S101 "YES"), a group of detected steering torque is statistically processed in every steering direction (step S102-S106) and one side flow suppression control for giving one side flow suppression steering assistant force according to the statistic processing result is executed (step S107 and S108). Therefore, when a steering direction is switched, steering torque and a steering angle are stagnated by friction of a steering system, and a peak in the steering torque in steering in a left direction and a peak in the steering torque in steering in a right direction are generated on a frequency distribution in which the steering torque is rounded up after it is determined that the vehicle is linearly traveled. Even if large difference is generated on the magnitude (frequency of steering in the left direction and frequency of steering in the right direction) of the two peaks, more suitable one side flow suppression steering assistant force can be set. As a result, one side flow of the vehicle can be more certainly suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a steering controlling device which can compensate a regular disturbance input to a vehicle without obstructing the transmission of information of a flat tire occurrence, and to provide an automobile equipped with the steering controlling device, and a steering controlling method. SOLUTION: The disturbance input to the vehicle is estimated based on the history of a steering torque under a linear running state of the vehicle. A disturbance compensating steering assisting force is imparted in the direction for suppressing the steering torque which is generated by the disturbance in response to the estimated disturbance estimation value. In this case, if a blowout of a wheel is detected, the disturbance compensating steering assisting force is reduced and corrected to a disturbance estimated value at the time of the occurrence of the blowout.
