Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle control, in particular to a reversing lamp and a reversing buzzer driving system for a single-engine hydrostatic vehicle. Background Art
[0002] Single-engine hydrostatic models can take into account the needs of high-speed transfer and low-speed stable operation of some working vehicles, such as washing and sweeping vehicles, high-pressure cleaning vehicles, asphalt spreading vehicles, etc., and are favored by various special vehicle manufacturers. Vehicle reversing safety is a must-have element in the development of single-engine hydrostatic models. When a single-engine hydrostatic model works in mechanical direct drive mode, the reversing light and reversing buzzer drive method of a conventional double-engine model can be adopted, that is, the reversing light relay is driven by the chassis transmission R gear signal, so that the left and right reversing lights are lit and the reversing buzzer works, and the surrounding pedestrians and vehicles are prompted to avoid by light signals and sound signals, thereby improving the safety of vehicle operation. However, when the vehicle is working in hydrostatic mode, the chassis transmission is generally kept in direct gear. When reversing, the travel hydraulic motor is mainly controlled to reverse by turning on the hydraulic reversing switch, thereby realizing the reversing function. Therefore, when a single-engine hydrostatic model works in hydrostatic mode, the reversing light and reversing buzzer drive method of a conventional double-engine model cannot meet the use requirements.
