Abstract
The invention provides a tire blowout braking control system, belonging to the field of automobile safety technique. The invention solves the problems of ruder and crueler braking action and stability deficiency of the existing automobile tire blowout braking system of. The tire blowout braking control system provided by the invention comprises a control device and a tire pressure monitoring unit for detecting the tire blowout state, wherein the control device is connected with an engine control unit and the tire pressure monitoring unit; and the control device can control the tire braking and reduces the engine torque through the engine control unit when the tire blowout signal fed back by the tire pressure monitoring unit is received. The invention has the advantages that when the tire blowout braking control system inducts the occurrence of tire blowout, on one hand, the emergent braking is carried out, on the other hand, the engine torque is reduced, thereby reducing the speed of the automobile; and the two hands are simultaneously carried out, thus the tire blowout braking course is milder and the stability is higher.
Description
Technical field
The invention belongs to the automotive safety technical field, relate to a kind of vehicle safety travel system, particularly a kind of braking control system of blowing out.
Background technology
Vehicle is in running at high speed, the consequence that causes of blowing out is very fearful, have data to show: the death toll that causes because of blowing out of running at high speed accounts for 49.81% of freeway accident death by accident number, accounts for 63.94% of number of injured people, accounts for 43.38% of direct property loss.So running at high speed blows out is acknowledged as the No.1 killer of high-speed travel state down train safety, this also is that a domestic and international automotive expert is wanted a great problem that solves always.
Existing brake system of car (as the BMBS system of our company), can implement braking to vehicle in the moment of blowing out, vehicle can be stopped reposefully, as a kind of flat tire braking system (its publication number is CN101590827A) that Chinese patent provided, the flat tire braking system that this patent provided is except monitoring the air pressure of tire in real time and providing the too high or too low early warning of tire pressure, can also utilize the electronic vacuum servo-unit to break into powerful braking force in the moment of the generation of blowing out and force automobile brake and deceleration, and under the support of ABS, make automobile be in slave mode, thereby ensure the person and property safety.
BMBS utilizes electronic vacuum servo-unit EVB to realize heavy braking, and effect is obvious, but has only utilized the drg deceleration, and braking maneuver is barbarous relatively roughly, deficient in stability.
Summary of the invention
The objective of the invention is at the existing the problems referred to above of existing automobile flat tire brake system, and proposed a kind of braking control system of blowing out that in braking, can also reduce engine torque, make the braking of blowing out more gentle stable.
Purpose of the present invention can realize by following technical proposal: a kind of braking control system of blowing out, comprise control setup and the tire pressure monitoring unit that is used to detect the situation of blowing out, it is characterized in that, described control setup is connected with the tire pressure monitoring unit with control unit of engine, and described control setup may command tire when receiving the signal of tyre burst of tire pressure monitoring unit feedback is braked and reduced engine torque by control unit of engine.
The tire pressure monitoring unit is sent to control setup with the information of blowing out after detecting and having taken place to blow out, and carries out emergency braking by control setup; Simultaneously, control setup sends the control signal of minimizing engine torque to control unit of engine, and the output torque by control unit of engine adjusting driving engine reduces the speed of a motor vehicle, is implemented in the moderating process vehicle stabilization state is control effectively.
In above-mentioned a kind of braking control system of blowing out, described control setup is electronic stabilizing control system (ESC).Electronic stabilizing control system ESC can help to avoid causing danger, and when vehicle is extremely unstable, by car side brake or control engine torque, compensates the stability of vehicle.
In above-mentioned a kind of braking control system of blowing out, all connect between described tire pressure monitoring unit, control setup and the control unit of engine by the CAN bus.
In above-mentioned a kind of braking control system of blowing out, described tire pressure monitoring unit comprises signal processor, signal projector, signal receiver and monitoring sensor, signal projector and monitoring sensor are connected the signal processor two ends, signal processor, signal projector and monitoring sensor connect the monitoring power supply, and signal receiver is connected with control setup.
The monitoring power supply is a battery, signal processor, signal projector and monitoring sensor all drive work by battery, this monitoring sensor comprises multiclass sensor, be respectively pressure sensor, temperature sensor and acceleration pick-up, this monitoring sensor is installed on 4 tires of vehicle, when blowing out, sensor sends to signal processor with the data that collect, signal processor sends to signal receiver through signal projector with signal, by signal receiver signal is sent to control setup again, control setup is moved according to the signal that receives.
Compared with prior art, the braking control system of originally blowing out is blown out when taking place sensing, and carries out emergency braking on the one hand, reduces engine torque on the other hand, lowers the speed of a motor vehicle, works along both lines in two aspects, and the braking procedure of blowing out is more gentle, and stability is higher.
