Title:
MIXING DRUM ROTATIONAL SPEED CONTROL METHOD AND APPARATUS, AND MIXER TRUCK
Document Type and Number:
WIPO Patent Application WO/2023/024751
Kind Code:
A1
Abstract:
A mixing drum rotational speed control method and apparatus, and a mixer truck. The method comprises: acquiring the current rotational speed of a mixing drum driving motor; and determining, on the basis of the current rotational speed and a deceleration gear table, the current deceleration gear and a set holding time corresponding to the current deceleration gear, and performing gear-by-gear speed reduction control on the mixing drum driving motor, wherein the deceleration gear table comprises a plurality of deceleration gears configured according to decreasing control rotational speeds, and set holding times corresponding to the deceleration gears. The rotational speed of the mixing drum is continuously controlled, so that the phenomenon of discharging caused by instantaneous reverse rotation due to inertia is avoided, thereby avoiding a reverse impact force to the maximum extent, relieving driving discomfort, and improving driving experience of a driver.
