Control unit and method for belt slip detection in construction equipment

Abstract

A control unit (101, 801, 1000) for construction equipment (100, 800), configured to detect belt slip in a drive arrangement (200, 830), the drive arrangement (200, 830) comprising pulleys (210, 220, 840, 850) and at least one drive belt (230, 860) arranged to connect a motor axle (125, 870) to one or more tool axles (135, 880) of the construction equipment (100, 800), the control unit (101, 801, 1000) comprising processing circuitry (1010) configured to obtain an expected amount of effort required to accelerate the motor axle (125) from a first velocity (ω0) to a second velocity (ω1), measure an actual amount of effort required to accelerate the motor axle (125) from the first velocity (ω0) to the second velocity (ω1), and detect belt slip in the drive arrangement (200) in case the expected amount of effort exceeds the measured actual amount of effort by a margin.
