Vehicle crane control method and device, and vehicle crane

Abstract

The invention relates to a vehicle crane control method and device, and a vehicle crane. The method comprises the following steps of determining a voltage target value according to a received input signal for starting a crane from a control handle; determining an intermediate voltage value according to a first voltage value and the voltage target value; and when each signal output time point of afirst control time period is reached, determining and outputting a first output voltage corresponding to the signal output time point, wherein the first output voltage at a first target time point isthe intermediate voltage value, the first output voltage of a time end point of a first control time period is a voltage target value, and in the first time period formed by a time starting point of the first control time period and the first target time point, an increasing amplitude of the first output voltage corresponding to a latter signal output time point is increased along with the increase of time compared with the increasing amplitude of the first output voltage corresponding to a former signal output time point. Therefore, good micro-motion performance is achieved on control of thecrane, and large shaking in a starting process is prevented.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, relates to a control method and device for a vehicle crane and a vehicle crane. Background technique [0002] The vehicle crane is a kind of crane installed on the chassis of ordinary vehicles or special vehicles, and consists of two parts: getting on the car and getting off the car. The performance of the off-board chassis is equivalent to that of a load-carrying vehicle with the same total weight of the whole vehicle, and it can be driven on the road. The car is a kind of machine that does cyclical and intermittent movements. It uses the pick-up device to lift the item from the pick-up place, and then moves the object to the designated place and lowers it. The movement of the vehicle crane on the vehicle includes four main actions: boom luffing, boom telescoping, turntable rotation, and winch retraction. During the operation, the operator is located in the operating room wh...
