Abstract
This vehicle motion control apparatus obtains a yaw rate deviation by subtracting the value (actual-yaw-rate-after-low-pass-filter-process Yrfilter), which is obtained by providing with a time constant τ(>τ) the low-pass filter process to the actual yaw rate Yr obtained from the yaw rate sensor incorporated in the HU, from the value (turning-angle-yaw-rate-after-low-pass-filter-process Yrtfilter) obtained by providing with the time constant τthe low-pass filter process to the turning angle yaw rate Yrt obtained on the basis of the actual steering angle obtained from the steering angle sensor, which is provided separate from the hydraulic unit HU. When this yaw rate deviation exceeds the threshold value Yrth (time t), this apparatus starts an under-steer suppression control.
