CONTROL DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP2009275626
Kind Code:
A
Abstract:
To maintain driving force required for a vehicle and restrain overheat of hydraulic fluid of a transmission with a control device adopted to a vehicle equipped with a heat exchanger for exchanging heat between cooling water of an internal combustion engine and the hydraulic fluid of the transmission.
Automatic shift of a change gear ratio of the transmission 20 to a larger side is prohibited when temperature To of the hydraulic fluid detected by an oil temperature sensor 25 is the predetermined temperature Ta or more. When automatic shift of the change gear ratio of the transmission 20 to a larger side is prohibited, output torque of the internal combustion engine 10 is increased to obtain required driving force of the vehicle 1.
