METHOD FOR CONTROLLING FOUR-WHEEL-DRIVE SYSTEM ACCOMPANYING BOOSTER

WIPO Patent Application WO/2022/070794

A1

The present invention provides a method for controlling a four-wheel-drive system accompanying a booster. The four-wheel-drive system accompanying a booster has: a battery (BAT) as a drive power source of a vehicle; a plurality of drive units connected in parallel to the battery (BAT); a plurality of inverter units (INV) connected, respectively, to the drive units; and a booster device (VVC). Each of the plurality of drive units has: a front-wheel-side drive unit connected to the battery (BAT) via the booster device (VVC); and a rear-wheel-side drive unit connected to the battery (BAT) not via the booster device (VVC). The output power of the front-wheel-side drive units is set to be greater than the output power of the rear-wheel-side drive units, and the output power of the rear-wheel-side drive units is set to be greater than the boost power of the booster device (VVC). A control method controls the front-wheel-side drive units and the rear-wheel-side drive units so that the output via the booster device (VVC) does not exceed the rated boost output of the booster device (VVC).
