The invention relates to a driving control method. A traveling pump provides power for driving actions, the control method comprises the steps of inquiring the current driving state according to a preset driving state table; acquiring relevant driving parameter signals: real-time rotating speed of an engine; obtaining a judgment result of whether the current driving state is accelerated or not bytaking whether the engine speed is greater than a preset speed or not; selectively sending out a control signal for reducing the output flow of the traveling pump or not according to the judgment result; and when the judgment result is that the current driving state is downhill and accelerated driving is carried out, sending a control signal for reducing the output flow of the traveling pump out.According to the driving control method, the vehicle can stably go downhill in a downhill acceleration driving state. The invention further provides a driving controller, a driving control system andan aerial working vehicle.
Description
technical field [0001] The invention relates to the technical field of aerial work vehicles, in particular to a driving control method, a controller, a control system and an aerial work vehicle. Background technique [0002] The aerial work vehicle is mainly composed of a chassis assembly, a boom assembly and a working platform. The boom assembly is set on the chassis assembly, and the working platform is set on the boom assembly. Its advantages such as simple structure, small size, large starting torque, and small reversing impact are widely used in aerial work vehicles. [0003] The closed travel hydraulic system includes a travel pump and a hydraulic motor. When working, the high-pressure oil output by the travel pump directly drives the motor and drives the vehicle to travel through the reducer. Specifically, the engine is directly connected to the travel pump through a coupling, the A port of the travel pump is connected to the A port of the hydraulic motor, the B port...
