Abstract

An embodiment of the present application provides an electrohydraulic power steering pump controller detection system, the system includes a hydraulic circuit for supplying oil to the steering pump and an electrical control circuit, and the hydraulic circuit includes a cooling system circuit, a heating system circuit, and an electrical control circuit. For the oil supply circuit that supplies oil to the steering pump, the electrical control circuit includes a power supply, a DC power supply that is electrically connected to the power supply in turn, and a steering pump controller. The steering pump motor is controlled by the steering pump controller, and produces a series of actions in a certain hydraulic working environment. By collecting the feedback data from the steering pump motor, the stability and reliability of the steering pump controller can be detected.

Description

technical field [0001] The present application relates to the technical field of steering pump controller performance detection, in particular to an electrohydraulic power steering pump controller detection device, system and method. Background technique [0002] In the vehicle control system, the power steering pump enables the vehicle to change or maintain the driving direction according to the driver's will, and can alleviate the impact from the road. In traditional fuel vehicles, the power steering pump is connected to the engine through a conveyor belt or gears, so that the speed of the power steering pump is related to the speed of the engine, that is, the engine cannot freely adjust the speed of the power steering pump. During the actual steering process, the speed of the engine directly It determines the speed of the steering pump, which ultimately leads to an increase in the energy consumption of fuel vehicles. [0003] Electric vehicles are different from traditio...
