A truck safety early warning braking system

Abstract

The invention discloses a novel truck safety early warning braking system. The truck safety early warning braking system includes a front part and a carriage part, and the carriage part can be bootstrapped to support the front of the truck to change the trailer, and the front automatically collects relevant parameters of the trailer after changing the trailer , the device of the present invention can automatically remind the driver when the truck is turning, and can also project a warning line and a dangerous area on the ground to remind the driver and passers-by beside the truck to avoid in time, and automatically brake when danger occurs, increasing the safety of the truck. active safety features.

Description

technical field [0001] The invention relates to the field of truck driving safety control, in particular to a truck safety early warning braking system. Background technique [0002] Due to the long length and wide width of the truck, truck drivers have many blind spots that cannot be monitored in real time. When the truck is turning, the rear wheels do not follow the track of the front wheels, and the turning radius of the rear wheels will be smaller than that of the front wheels. The deviation of the center of the turning circle, the deviation formed by the turning is called the inner wheel difference. The area between the turning arc of the front wheel of the truck and the arc drawn by the turning of the rear wheel is the dangerous area. The longer the body, the larger the dangerous area formed. In this area The dynamic part overlaps with the driver's visual blind spot, which is very easy to cause personal accidents and property losses after non-motor vehicles or pedestri...

Problems solved by technology

[0003] 1. Invention patents with announcement numbers of "CN201510969225", "CN 107985200 A", and "CN 107839590 A" do not support the exchange between the front and the carriage. Trucks often use the front and carriage (trailer) separately, that is, the front and carriage ( Trailer) is not one-to-one correspondence, and the length of the compartment (trailer) is not fixed. The above-mentioned patent does not support the separation of the front and compartment (trailer). unavailable

[0004] 2. Invention patents with announcement numbers "CN201510969225", "CN 107985200 A", and "CN 107839590 A" do not support multiple trailers, and the products described in the above patents cannot be used when the truck has multiple trailers

[0005] 3. The invention patents with the announcement number "CN201510969225", "CN 107985200 A" and "CN 107839590 A" do not support automatic braking in case of emergency. The invention patent with the announcement number "201711112829. The difference between accelerator and brake is that controlling the accelerator only controls the acceleration of the truck, and does not hinder the truck from sliding. When the truck is turning, if there is an emergency, it needs to brake in time, but controlling the accelerator will not produce the effect of braking. In an emergency, control The accelerator is effective, but the effect is not in place. Only by controlling the brakes can the designer's design intention be achieved

[0006] 4. Invention patents with announcement numbers "CN201510969225", "CN 107985200 A", and "CN 107839590 A" do not support the calculation of the inner wheel difference, and correspondingly cannot calculate the size and position of the dangerous area caused by the inner wheel difference. The area area and position are detected to detect the corresponding position and whether there are objects in the dangerous area, and it is impossible to judge whether braking or early warning is required based on this

[0007] 5. The invention patents with announcement numbers "CN201510969225", "CN 107985200 A", and "CN 107839590 A" do not add corresponding detection calculations and considerations to both sides of the front body, and the area and location of the dangerous areas on both sides of the front body The calculation method is different from that of semi-trailers and trailers. Most of the front body has double front and rear wheels. When turning, the front and rear double rows of wheels turn at the same time. There will be an included angle with the direction of the car body, and the rear wheels will not have an included angle with the direction of the car body

[0008] 6. The invention patents with the announcement numbers "CN201510969225", "CN 107985200 A", and "CN 107839590 A" did not take into account that the truck is relatively high. The detection device generally emits ultrasonic waves, light, etc., and the emitted ultrasonic waves have an angle. If The installation of the detection device is relatively high, and this angle will cause an area of ​​the low object to be undetectable. If the detection device is installed relatively low, this angle will cause an area of ​​the high object to be undetectable. There will be blind spots caused by the invention itself, and the practicability is poor
