Vehicle skid control device, automobile with vehicle skid control device mounted thereon, and vehicle skid control method

摘要

Under the condition of a large variation DeltaTm in motor torque demand Tm*, the significant torque change may lead to some vibration of a vehicle to temporarily heighten an angular acceleration alpha. The temporary rise of the angular acceleration alpha may cause the angular acceleration alpha to exceed a preset threshold value alphaslip and result in misdetection of the occurrence of a 'phantom' skid in an angular acceleration alpha-based skid state determination (step S 112 ). The drive control of the invention accordingly specifies a potential for misdetection of the occurrence of a 'phantom' skid when the variation DeltaTm in motor torque demand Tm* exceeds a preset threshold value Tthr at step S 108 . The drive control thereby does not execute skid occurring state control (step S 120 ) with torque restriction but performs grip state control at step S 116.
