What are the manifestations of a damaged BYD electro-hydraulic module?
1 Answers
The manifestations of a damaged BYD electro-hydraulic module include reduced power, noticeable idling, and inability to accelerate properly. Below is relevant information about electro-hydraulic control: 1. Definition: Electro-hydraulic control refers to a control method in hydraulic transmission and control that can accept analog or digital signals, enabling continuous proportional control of output flow or pressure. 2. Components of electro-hydraulic control: The components of electro-hydraulic control in the electro-hydraulic module include command elements, comparison elements, electronic controllers, proportional valves, and hydraulic actuators. Command elements generate and input control signals. They can also be referred to as programmers or input circuits. In the presence of feedback signals, they provide control signals of the same form and magnitude as the feedback signals. The function of comparison elements is to compare given inputs with feedback signals, producing deviation signals that serve as inputs to the electronic controller. The electronic controller, often called a proportional amplifier, is necessary because the control current required by the electromagnets in the proportional valve is larger than the small deviation control current, which is insufficient to drive the electromagnets. Therefore, the control signal needs to be power-amplified.
