Guardrail cleaning vehicle driving system with functions of constant speed cruising and steering fine adjustment

Abstract

The invention discloses a guardrail cleaning vehicle driving system with functions of constant speed cruising and steering fine adjustment. The guardrail cleaning vehicle driving system comprises an accelerator pedal control device and an automatic steering device. The accelerator pedal control device comprises a constant speed mechanism for controlling the inclination angle of an accelerator pedal and a locking mechanism for fixing the position of the constant speed mechanism; the constant speed mechanism comprises a mainspring, a roller and a pull wire; the locking mechanism comprises a locking electromagnet, a locking groove, a magnetic locking column and a locking block; the magnetic locking column is positioned between the locking block and the locking electromagnet; the magnetic locking column is locked in or detached from the locking groove under the magnetic force of the locking electromagnet; the automatic steering device comprises a millimeter wave radar sensor, a torque sensor and a steering transmission mechanism which is used for driving a steering wheel to rotate; and the millimeter wave radar sensor is mounted on one side, near a guardrail, of a vehicle body. Different from a conventional driving assisting system, the guardrail cleaning vehicle driving system with the functions of constant speed cruising and steering fine adjustment has flexible and simple operation, stable work and high degree of automation, and can assist an operator in driving at a constant speed in a running process, thereby avoiding distraction and reducing potential safety hazards.

Description

technical field [0001] The invention belongs to the field of auxiliary driving, and relates to a driving system of a guardrail cleaning vehicle with the functions of constant-speed cruise and steering fine-tuning. Background technique [0002] During the working process of the guardrail cleaning vehicle, the driver needs to keep the accelerator at the same position and drive at a constant speed, which may easily cause numbness in the legs and feet and cause fatigue driving; in the process of cleaning the guardrail, in order to ensure the safety and cleaning quality of the guardrail and roller brush, the driver It is necessary to observe the position of the roller brush and the guardrail all the time, and adjust the angle, which can easily cause distracted driving and driving fatigue. [0003] Most of the constant speed cruises commonly used in the market currently use an automatic cruise system based on the PID fuzzy algorithm, and the steering system, before the present inv...

Problems solved by technology

However, the disadvantages of this device are also obvious: the gear transmission cannot ensure that the gear meshes with another gear during the up and down movement, and it is easy to hit the teeth; the motor cannot control the rotation angle, so the steering range cannot be controlled; the gear and the motor occupy a large space; The device cannot perform collision warning, and there are potential safety hazards; the degree of automation of the device is not high
