Abstract
In a vehicle control system that includes an engine, a first rotary electric machine, a second rotary electric machine and a transmission, a control unit includes a shift state acquisition module that acquires a shift state of a vehicle; a stepped-up voltage reduction permission module that determines whether reduction of a system voltage is permitted on the basis of the acquired shift state; a stepped-up voltage reduction execution module that reduces the system voltage to a predetermined upper limit voltage when reduction of the system voltage is permitted; and a drive control module that controls operations of a converter and inverter to thereby control the first rotary electric machine and the second rotary electric machine.
