SLIP CONTROL SYSTEM OF INDEPENDENTLY DRIVEN ELECTRIC PLATFORM

WIPO Patent Application WO/2023/018293

A1

The present invention relates to a slip control system of an independently driven electric platform of an agricultural machine such as a tractor. An agricultural machine such as a tractor is supposed to operate on soil having a high level of moisture content or having a low level of strength, and wheels thereof are thus supposed to slip. The present invention relates to a slip control system for controlling such slip and, more particularly, to a slip control system of an independently driven electric platform, the slip control system comprising: four motors (M) for driving wheels of respective shafts in order to drive an electrically driven tractor (T); a velocity measuring sensor (Sv) for measuring the velocity (VG) of the electrically driven tractor (T); a rotational velocity measuring sensor (Sm) for measuring the rotational velocity (RM) of the motor (M); and an inverter (I) for controlling the rotational velocity and output of the motor (M). Respective values measured by the velocity measuring sensor (Sv) and the rotational velocity measuring sensor (Sm) are compared, and the voltage applied to the inverter (I) is controlled according to a slip ratio.
