Control device for automatic transmission

A control device for an automatic transmission, comprising:

• a brake configured to be engaged when a vehicle starts traveling;
• a clutch;
• an oil temperature sensor that detects a temperature of oil stored in the automatic transmission;
• and
• a processor configured to execute lubricant supply control logic to control supply of lubricant to the brake and the clutch and calculate a temperature of the brake and a temperature of the clutch based at least on the sensed oil temperature,
• wherein the lubricant supply control logic switches a supply amount of lubricant to the brake according to the temperature of the brake, and switches a supply amount of lubricant to the clutch according to the temperature of the clutch,
• wherein the lubricant supply control logic is provided with lubricant supply patterns for switching a supply destination of lubricant and a supply amount of lubricant to the supply destination, and
• wherein the lubricant supply patterns include:
• a first lubricant supply pattern in which the supply amount of lubricant to the brake is set as a given first flow rate, and the supply amount of lubricant to the clutch is set as a given second flow rate,
• a second lubricant supply pattern in which the supply amount of lubricant to the brake is set as the given first flow rate, and the supply amount of lubricant to the clutch is set as a given third flow rate greater than the given second flow rate;
• a third lubricant supply pattern in which the supply amount of lubricant to the brake is set as a given fourth flow rate greater than the given first flow rate, and the supply amount of lubricant to the clutch is set as the given second flow rate;
• and
• a fourth lubricant supply pattern in which the supply amount of lubricant to the brake is set as the given fourth flow rate, and the supply amount of lubricant to the clutch is set as the given third flow rate.
