Hybrid vehicle control device

A hybrid vehicle control device for a hybrid vehicle including an engine, a motor generator, and a belt-type continuously variable transmission, the hybrid vehicle control device comprising:

• a controller configured to:
• perform a low speed position return expediting control in response to a downshift request accompanying deceleration, wherein the low speed position return expediting control is configured to:
• increase a differential pressure between a primary pressure and a secondary pressure and cause a downshift toward a lowest speed position transmission ratio by reducing the primary pressure;
• and further reduce the primary pressure in response to a condition that the secondary pressure becomes greater than or equal to a trigger threshold value during the downshift;
• terminate the low speed position return expediting control in response to a condition that an actual secondary pressure decreases to a secondary pressure minimum level;
• and
• set a secondary pressure lower limit higher than the secondary pressure minimum level during the low speed position return expediting control, wherein the secondary pressure lower limit is a lower limit value of the secondary pressure.
