Anti-rear-end collision device and method

Abstract

The invention discloses an anti-rear-end-collision device and method. The anti-rear-end-collision device comprises a frame, a brake plate and an accelerator plate, wherein an accelerator shaft is arranged on the frame in the left-right direction, a brake shaft is arranged on the frame in the left-right direction, the accelerator shaft is arranged on the left side of the brake shaft, an acceleratorgear is arranged on the accelerator shaft, the accelerator gear is in coaxial transmission connection with the accelerator shaft, and a first friction plate perpendicular to the brake shaft is fixedly arranged at the right end of the brake shaft; a first transfer shaft and a second transfer shaft are arranged on the frame, a second friction disc is arranged at the left end of the first transfer shaft, a first gear is arranged on the first transfer shaft, a second gear is arranged on the second transfer shaft, the first gear is meshed with the second gear, and a transfer gear is arranged on the second transfer shaft; and a driving device is arranged on the frame, a linkage plate is connected to the driving device in a driving mode, and the linkage plate is connected to the accelerator shaft, the first transfer shaft and the second transfer shaft. The anti-rear-end-collision device solves the problem that the brake effect can not be carried out in a traditional detection and anti-rear-end collision device.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a rear-end collision prevention device and method. Background technique [0002] my country's car growth and ownership are at the forefront in the world. At the same time, the field of car safety has already become the focus of attention, and traffic accidents also occur occasionally in China. Some of these traffic accidents are caused by mistakenly stepping on the accelerator. traffic accident. [0003] Brake Override System (BOS) refers to a system that allows the driver to stop the car by pressing the brake pedal even when the driver depresses the accelerator pedal and the accelerator is fully open (that is, the accelerator is fully depressed). The brake priority system is widely used in automobiles. [0004] In the automobiles on the market, the detection methods generally include: first, use a pressure sensor to detect whether the accelerator pedal has been stepped on by mistake;...

AI Technical Summary

Problems solved by technology

However, the anti-rear collision device using the above two detection methods is only a danger alarm system, but does not actively provide a solution, so that the driver wastes some reaction time in the process of receiving the alarm and stepping on the brakes, that is, the actual operation There is a certain delay on the road, resulting in the consequences of accidentally stepping on the accelerator, which may still be unavoidable
