Control device for vehicle

摘要

In a control device for a vehicle that controls a revolution speed of a drive power source or a gear ratio of a transmission coupled to an output side of the drive power source in the vehicle equipped with the drive power source and the transmission, the control device is configured to determine an index that is based on a running state of the vehicle, and to control a required revolution speed of the drive power source or a required gear ratio for the transmission on the basis of the index.

1. A control device for a vehicle that controls a revolution speed of a drive power source or a gear ratio of a transmission coupled to an output side of the drive power source in the vehicle equipped with the drive power source and the transmission, the control device being configured to:
determine an index that is based on a running state of the vehicle, which is in accordance with driver's intention; and control a required revolution speed of the drive power source or a required gear ratio for the transmission based on the index, wherein: the index is increased when at least one of an obtained longitudinal vehicle acceleration value or an obtained transverse vehicle acceleration value, which are each repeatedly obtained during running of the vehicle, is larger than a previously obtained value, and the index is slowly decreased as compared to the index increased when the obtained value is smaller than the previously obtained value, the required revolution speed or the required gear ratio is established in advance according to a speed of the vehicle and the index, a required maximum acceleration ratio that is established in advance according to the index is determined based on the index, and a required acceleration for each vehicle speed is determined based on a maximum generated acceleration and the required maximum acceleration ratio for each vehicle speed, and the required revolution speed or the required gear ratio is set based on the required acceleration.
