摘要: A steering control section has a first steering angle correction amount calculating section, a second steering angle correction amount calculating section, and a motor rotational angle calculating section. The first correction amount calculating section calculates a first correction amount based on a vehicle speed and an actual steering wheel angle. The second correction amount calculating section calculates a second correction amount through multiplying a control gain corresponding to the vehicle speed with a value calculated by low-pass filtering a differential value of steering wheel angle. The motor rotational angle calculating section calculates a motor rotational angle corresponding to the value adding the first and second steering angle correction amount, and outputs it to a motor driving section so as to drive an electric motor for correcting the steering angle. Thereby, an unstable vehicle behavior due to a resonance of a yaw motion caused in the steering operation can be suppressed.

摘要: A road-surface friction-coefficient estimating device compares a rack-thrust-force deviation value with a preliminarily set maximum-value-determination threshold value. If the rack-thrust-force deviation value is above the maximum-value-determination threshold value, the device determines that tires are slipping, and sets a front-wheel friction-circle utilization rate in that state as a road-surface friction coefficient. If the rack-thrust-force deviation value is below the maximum-value-determination threshold value, the device refers to a preliminarily set map to determine a restoring speed at which the road-surface friction coefficient is to be restored to 1.0 based on a vehicle speed and a front-wheel slip angle. While restoring the road-surface friction coefficient at the restoring speed, the device calculates and outputs the road-surface friction coefficient.

摘要: Steering stability of a vehicle under a traveling state such as cornering is enhanced by controlling a state of the vehicle based on cornering powers of right and left wheels. A detecting unit 1 detects action force containing longitudinal force Fx, lateral force Fy and vertical force Fz which act on each wheel. A specifying unit 2 specifies a friction coefficient between the wheels and road surface. An estimating unit 6 estimates cornering power ka of each wheel based on the action force and the friction coefficient. A processing unit 7 determines control values so that the representative value ka_ave of the cornering powers concerning the right and left wheels is larger than the present value of the representative value ka_ave of the cornering powers concerning the right and left wheels. Controlling units 8 to 10 control the state of the vehicle based on the control values thus determined.
