常処理装置。 Excessive slip signal generating means detects an excessive slip state of a driving wheel of a vehicle and generates an excessive slip signal when the driving wheel is in a predetermined slip state, and a driving wheel torque is generated based on the excessive slip signal of the excessive slip signal generating means. a driving wheel torque reduction control means for performing reduction control; a controllability determination means for determining a controllability state of the driving wheel torque reduction control means;
In the abnormality processing device for a drive wheel excessive slip control device, the abnormality processing device for a driving wheel excessive slip control device is provided with an operation stopping means for stopping the operation of the excessive slip signal generating means when the output of the control possibility determining means is a signal indicating that control is impossible. If the excessive slip state of the drive wheel is detected by the excessive slip signal generating means within a predetermined time period before the signal indicating that control is not possible is output from the determining means, the stop operation by the operation stopping means is performed. An abnormality processing device for a driving wheel excessive slip control device, characterized in that a delaying means is provided.
