PURPOSE:To reduce production of transmission shock and to improve durability of a frictional engaging device, by a method wherein an oil pressure in the oil pressure control device of an automatic transmission is controlled and set in linkage with the selection value of the supercharge pressure of a supercharging means. CONSTITUTION:A supercharging means, capable of selecting a supercharge pressure to be engine continuously and steppedly, is provided. A means 44 is provided for controlling and setting an oil pressure in an oil pressure control device 39 of an automatic transmission in linkage with the selection value of the supercharge value of a supercharging means. This constitution enables reduction of production of transmission shock, and improvement of durability of a frictional engaging means. |
