Truck tractor and trailer docking aid

Abstract

The invention discloses a truck tractor and trailer docking aid comprising a single-chip microcomputer (3) disposed in a tractor (1). A display screen (9) and operating keys (10) are arranged in a cab of the tractor (1) and connected outside the single-chip microcomputer (3). The tail of the tractor (1) is provided with a camera connected with the single-chip microcomputer (3); the camera is used for filming the road behind the tractor (1) and a connecting part of the tractor (1). Microwave radar ranging sensors connected with the single-chip microcomputer (3) are arranged at two ends of the tail of the tractor (1) respectively. An audio chip (11) is connected outside the single-chip microcomputer (3), and a speaker (12) is connected outside the audio chip (11). The road behind the tractor (1) and the connecting part are filmed at the same time and displayed through the display screen (9), so that blind spots for backing up and docking are eliminated for drivers. The single-chip microcomputer (3) measures and calculates a distance between the tractor (1) and a trailer (2) and an alignment angle according to distance information fed back by the microwave radar ranging sensors, a reference backing-up path is displayed to a driver to guide for backing up, and the tractor (1) and the trailer (2) are docked conveniently and quickly.

Description

technical field [0001] The invention relates to a vehicle docking device, in particular to a device for auxiliary docking between an automobile tractor and a trailer. Background technique [0002] It is known that the tractor and the trailer need to be docked before the tractor is used to tow the trailer. Usually, the tractor and the trailer must be aligned first, and then the two are connected together through the connecting parts; however, in the actual operation process Among them, the docking area behind the tractor is a blind spot for the driver, which not only requires the driver to have high driving skills, but also requires an experienced commander outside the vehicle to command. The driver is easily nervous when operating in the blind spot. If the commander guides Inappropriate, or external environmental interference, etc., will cause the docking between the tractor and the trailer to fail, or the collision between the two vehicles during docking will cause equipmen...

[0002] It is known that the tractor and the trailer need to be docked before the tractor is used to tow the trailer. Usually, the tractor and the trailer must be aligned first, and then the two are connected together through the connecting parts; however, in the actual operation process Among them, the docking area behind the tractor is a blind spot for the driver, which not only requires the driver to have high driving skills, but also requires an experienced commander outside the vehicle to command. The driver is easily nervous when operating in the blind spot. If the commander guides Inappropriate, or external environmental interference, etc., will cause the docking between the tractor and the trailer to fail, or the collision between the two vehicles during docking will cause equipment damage and personal injury, which is not only time-consuming and labor-intensive, but also prone to danger.
