Problems solved by technology

[0003] The control unit used to receive the tire pressure signal in the existing tire blowout braking system is connected with the oil pump or the modified vacuum booster, so there is a delay phenomenon, because the execution unit is a mechanical component, such as the oil pump or the modified vacuum booster It takes a period of time to complete the execution action immediately after starting, and the delay reduces the response speed of the system and the reliability is low
At the same time, to configure the execution unit, it is necessary to rearrange the cabin settings and increase the cost and process steps for modifying the structure of the execution unit, so there are still disadvantages of complex structure and high production cost

Embodiment Construction

[0014] Such as figure 1 As shown, the present invention includes a tire pressure monitoring sensor 1 , a rotational speed sensor 2 , a braking system with ABS / ESP and a BMBS controller 3 . Both the power supply end of the braking system and the power supply end of the BMBS controller 3 are connected to the vehicle battery. The tire pressure monitoring sensor 1 is located in each wheel of the car, and it converts the air pressure value in the tire into an electrical parameter and transmits it to the BMBS controller 3 installed on the vehicle body through a wireless signal. The BMBS controller 3 has the function of data processing and analysis. The electronic control unit 4 of the braking system of ABS / ESP is connected. The brake system with ABS / ESP includes a pump motor 5, a hydraulic control unit and an electronic control unit 4. The hydraulic control unit includes an accumulator 7, an electromagnetic reversing valve 8, an electromagnetic isolation valve 9, a normally closed ...

Abstract

The invention discloses an anti-lock system-based tyre burst braking system, which avoids using an oil pump as an execution unit or a remanufactured vacuum booster. By combining a braking system with ABS / EPS, the tyre burst braking system directly serves as the execution unit and greatly simplifies the structure of the tyre burst braking system, so that rearrangements are not required in an engine compartment, the production process steps are reduced, and the production cost is reduced. Comparing the time from the sending of a command by a BMBS controller to the work start of the braking system with the ABS / ESP with the time for the prior structure to achieve braking, the time from the sending of a command by a BMBS controller to the work start of the braking system with the ABS / ESP is shorter, so the anti-lock system-based tyre burst braking system has a quick response speed.

Description

technology field; [0001] The invention relates to a tire blowout braking system based on an anti-lock braking system, which includes a tire pressure monitoring sensor, a braking system with ABS / ESP and a BMBS controller, Background technique [0002] The tire blowout braking system based on the anti-lock braking system can provide protection when the vehicle suddenly blows out during high-speed driving. It monitors the air pressure inside the tire through the tire pressure monitoring sensor. Once the tire blows out, it will monitor the blowout signal. , and send the signal to the control unit. After the control unit receives the tire blowout signal, it starts the execution unit and builds up the brake pressure in the hydraulic pipeline to brake the wheels, so that the vehicle can be realized in a very short time before people have time to react. Automatic braking to maintain the stability of the vehicle. For example, the Chinese patent announcement number announced on March...
