  • Patent number: 12017638
    Abstract: A vehicle includes: a motor generator as a drive source; an automatic transmission via which the motor generator is connected to driving wheels, the automatic transmission being configured to change a gear ratio; and a shift actuator for a driver to operate the gear ratio of the automatic transmission. A control device for the vehicle includes: a motor controlling portion configured to control output torque of the motor generator; and a gear shift controlling portion configured to control the gear ratio of the automatic transmission. In a case where the output torque has a negative value, when downshift is not requested by an operation on the shift actuator, the gear shift controlling portion prohibits a downshift process of downshifting the gear ratio of the automatic transmission, but when downshift is requested by an operation on the shift actuator, the gear shift controlling portion permits execution of the downshift process.
