Abstract
A drive control system includes a battery, a direct current/direct current converter, a first motor, a second motor, and a controller. The battery is a direct-current power supply. The direct current/direct current converter is connected to the battery. The first motor is connected to the direct current/direct current converter, and drives one of a front wheel and a rear wheel. The second motor is connected to the battery, and drives the other one of the front wheel and the rear wheel, which is different from the wheel that the first motor drives. The controller controls step-up operation of the direct current/direct current converter, and executes intermittent step-up control. When a required driving force of a vehicle changes during a stop of the direct current/direct current converter through the intermittent step-up control, the second motor outputs an amount of change in the required driving force.
