Document Type and Number:
Japanese Patent JP7055730
Kind Code:
B2
Abstract:
To achieve both facilitation of promotion temperature rise of a working fluid of a hydraulic type automatic transmission mounted on a vehicle and securing of an operation performance of the vehicle.SOLUTION: A control device for vehicle includes an automatic transmission 2 in which a working fluid is supplied, a driving source 1 in which a cooling fluid is supplied, and a heat exchanger 5 for performing heat exchange between the working fluid and the cooling fluid. The control device also has a control part 10 which performs shift limiting for prohibiting the transmission ratio of the automatic transmission 2 from becoming equal to or less than a predetermined transmission ratio, in the case where a temperature of the working fluid is equal to or less than a first set value. The control part 10 releases the shift limiting in the case where the temperature of the cooling fluid is higher than the temperature of the working fluid, even though the temperature of the working fluid is equal to or less than the first set value.SELECTED DRAWING: Figure 1
