CONTROL DEVICE FOR VEHICLE
DRIVE
June 4, 2026
When the vehicle is traveling in a state where the difference between the tire load rates is not larger than a predetermined load rate difference, learning control is performed. Therefore, the learning control can be performed in a wider range of the driving force as compared with a case where the learning control is performed during traveling in a state where the tire slip rate is small and a range of the driving force is minute. Even when the vehicle is traveling in a state where the difference between the tire load rates is not larger than the predetermined load rate difference, the learning control is not performed when the vehicle travels in the tire nonlinear region. Thus, an increase can be prevented or reduced in the learning error due to an increase in the change amount of the tire slip rate during traveling in the tire nonlinear region.
