Description

Technical Field

[0001] This utility model relates to the field of driver assistance technology, and in particular to the AEB system for sanitation vehicles and sanitation vehicles. Background Technology

[0002] Traditional urban sanitation vehicles (water sprinkler trucks or sanitation cleaning trucks) have large blind spots due to their overall vehicle structure and complex operating characteristics (mostly residential areas, with the main operating scenarios being roads where pedestrians and vehicles share the road), resulting in a high risk of traffic accidents, a large degree of damage from accidents, and significant economic losses. There is an urgent need for an active safety management system to assist safe driving. However, the existing vehicles have low technical configurations and incomplete safety facilities, which are insufficient to solve the above problems.

[0003] Currently, the application of 360-degree panoramic imaging in the fields of dump trucks and urban waste collection and sanitation is not yet ideal, mainly due to the following reasons:

[0004] It requires the driver to look down at the display screen, which is inconsistent with the traditional way of observing the surroundings through the car window and rearview mirror;

[0005] The equipment suffers from image distortion and discrepancy, resulting in a visual effect that differs from direct human observation.

[0006] The sanitation vehicles operate under complex conditions, with dusty and muddy environments, resulting in a high probability of camera obstruction, a high damage rate, and insufficient online effectiveness.

[0007] The large proportion of nighttime driving mileage for sanitation vehicles makes it difficult to meet drivers' requirements for image clarity under low light conditions.

[0008] The equipment is still only at the warning function stage, with a high false alarm rate and no active braking function. Drivers often turn off the system's audible alarm later on.

[0009] Therefore, this utility model is proposed. Utility Model Content

[0010] The main purpose of this utility model is to disclose an AEB system for sanitation vehicles, which is used to solve the problem of safe driving caused by the lack of driver assistance in sanitation vehicles in the prior art.

[0011] To achieve the above objectives, according to one aspect of this utility model, an AEB system for sanitation vehicles is provided, and the following technical solution is adopted:

[0012] The AEB system of sanitation vehicles includes: sensors for real-time monitoring of the vehicle body area based on the current vehicle speed; an audible and visual alarm device for reminding the vehicle of its current distance using tiered audible and visual alarms controlled by the AEB system; and a braking device for performing braking operations controlled by the AEB system. The sensors are wirelessly connected to the AEB system, and the AEB system is electrically connected to both the audible and visual alarm device and the braking device.

[0013] Furthermore, the light alarm device is set with the following parameters: a first-level warning time of 1.6s, a second-level warning time of 1.0s, and a dynamic driving braking intervention time of 0.85s.

[0014] Furthermore, the sensors include: an ultrasonic radar disposed at the front of the vehicle body, which is electrically connected to the AEB system; and a right-side ultrasonic radar disposed on the right side of the vehicle body, which is wirelessly connected to the AEB system.

[0015] Furthermore, the right-side ultrasonic radar includes: a right-side corner radar and a right-side body ultrasonic radar.

[0016] Furthermore, the audible and visual alarm devices are configured as follows: Level 1 alarm priority > Level 2 alarm priority > Level 3 alarm priority; when alarm levels are the same, the right-side area priority >

[0017] The front zone has higher priority than the rear zone; if an obstacle in the right front zone passes the vehicle at a speed greater than 2 m / s, no alarm or braking will be triggered; if an obstacle in the right side zone passes the vehicle at a speed greater than 3 m / s, no alarm or braking will be triggered.

[0018] When the vehicle passes an obstacle on the right at a speed greater than 3 m / s, it does not trigger an alarm or brake.

[0019] This invention provides a device that integrates blind spot monitoring and early warning with active braking by adding an AEB system to sanitation vehicles and modifying the AEB system with the addition of sensors covering various blind spots. By using a warning-before-braking approach, it significantly improves overall vehicle safety. According to another aspect of this invention, a sanitation vehicle is provided, including the aforementioned AEB system. Attached Figure Description
