Cleaning sweeper truck running speed control system, method and device as well as cleaning sweeper truck

Abstract

The invention discloses a cleaning sweeper truck running speed control system, method and device as well as a cleaning sweeper truck so as to improve the operation effect of the cleaning sweeper truck and reduce damages of parts of operation mechanisms. The cleaning sweeper truck running speed control system comprises a truck controller, an operation / running mode selecting device, a gear selecting device, a running speed input device, an engine control module and a running controller; the truck controller is used for transmitting the current mode and the current gear to the engine control module and the running controller and transmitting an input running speed to the running controller; the engine control module is used for determining a target rotation speed of an engine and controlling the engine to work according to the target rotation speed of the engine; the running controller is used for determining a target output distribution of a hydraulic pump according to the current mode and the current gear and controlling the hydraulic pump to output power to a running mechanism and a plurality of operation mechanisms according to the target output distribution; and when the input running speed is larger than a maximum running speed which corresponds to the current mode and the current gear, the running controller is used for controlling the running mechanism to run according to the maximum running speed.

Description

technical field [0001] The invention relates to the technical field of environmental sanitation machinery, in particular to a driving speed control system, method, device and a sweeping vehicle. Background technique [0002] The washing and sweeping vehicle is a vehicle for washing and cleaning the main roads in the city. In recent years, with the rapid development of my country's national economy, the work of urban sanitation and cleaning is increasing day by day, and the requirements for mechanized operations of urban cleaning are also gradually increasing. Therefore, more and more technicians have begun to pay attention to the research of cleaning vehicles. [0003] At present, a traditional washing and sweeping vehicle includes a chassis and a top-loading operation mechanism installed on the chassis. The top-loading operation mechanism includes a top-loading controller, an auxiliary engine, and working mechanisms such as a fan, a water pump, and a sweeping plate. Among ...

AI Technical Summary

Problems solved by technology

[0004] The defect in the above-mentioned prior art is that the driving speed of the sweeper is controlled by the driver based on subjective experience, and the accuracy of the control is not high, which often causes the sweeper to exceed the above speed range during operation, so that the operation cannot be guaranteed. Effect

If the cleaning vehicle runs at a high speed during operation, it will cause damage to the parts of the bodywork mechanism
