Description
Technical field
The utility model relates to a kind of auto parts machinery and detects attending device, particularly a kind of portable multifunctional ABS detector.
Background technology
Anti-lock braking system ABS full name is Anti-lock Brake System, is a kind of the have wheel lock up of preventing, shortening automobile brake distance, reduces tire wear, prevents the vehicle safety control system of advantages such as automobile sideslip, whipping.Anti-lock braking system ABS is made up of control assembly (ECU), K line, flash memory (FLASH), width modulation (PWM), debugging access interface (DAP), fieldbus (CAN).Wherein control assembly (ECU) full name is Electronic Control Unit; It is the core controller of ABS system; Its function is according to internally stored program and data the information of sensor input to be carried out computing, processing, judgement; Output order provides certain control information to solenoid valve then; The K line generally is used for detection system, belongs to monofilar mode, is a special line that carries out data transfer between control module and the diagnostic equipment of automobile; The English name of flash memory is " Flash Memory ", generally abbreviates " Flash " as, belongs to a kind of of memory devices, is a kind of involatile internal memory.The English of width modulation is " Pulse Width Modulation "; Be abbreviated as PWM; Be to utilize the numeral of microprocessor to export a kind of very effective technology that mimic channel is controlled, be widely used in from many fields of measurement, the power of communicating by letter control and conversion; The debugging access interface, Debug Access Port is the EBI that CPU provides, through this EBI, register that can access chip also can access system memory, can in the kernel operation, conduct interviews; CAN is the abbreviation of controller local area network (Controller Area Network), is one of most widely used fieldbus in the world.
The ABS system has become the requisite device of Hyundai Motor, but the ABS system also can bring some spinoffs in maintenance.As when break down in certain part of brake system of car, owing to the interference of ABS, also can make fault become confusing in the diagnostic procedure.The detection means of existing anti-blocking brake system of automobile ABS comprises that mainly OBD system, instrument detect and real vehicle detects three kinds of means.

But; The warning lamp of above-mentioned display part is according to certain rule composition DTC that glimmers; The driver need observe the code of flicker, and obtains concrete abort situation through consulting code table, and this has relatively high expectations to the maintainer's; The mode of the sudden strain of a muscle sign indicating number of the ECU that produces because of different manufacturers is all different with the implication of its sudden strain of a muscle sign indicating number, so the maintainer will be familiar with all types of ECU very much.
(2) instrument detects
The instrument detection mainly is meant encodes to confirm the position of fault with instrument measurement abs controller pin according to relevant fault diagnosis.But because the relation of the ECU installation site of most of automobile ABS system, ECU wire harness plug generally all is very difficult approaching, adds that the terminal of wire harness plug does not have label again; Make calibrating terminal relatively more difficult, the therefore normal connection terminal box that adopts is simultaneously owing to the form of automobile ABS system ECU wire harness plug, the number of terminal; And the function of terminal all is not quite similar; Therefore, the connection terminal box of being selected for use also is different with the difference of automobile ABS system, increases the difficulty of maintenance; And existing ABS detector can not detect the fault of ABS gear ring, can only through the maintenance personal with wheel one by one overhaul could differentiate the position of breaking down, for maintenance has brought inconvenience.The testing tool that the needs that utilize existing ABS instrument to carry out method of testing adopt is many, and testing tool is inconvenient to carry and complicated, and detection speed is slow, and requires the tester all will understand position, the title of each terminal of automobile ABS system ECU.
(3) real vehicle detects
Real vehicle detects and to be meant mainly that real vehicle is driven and to adopt self-detection system or instrument measurement to confirm the reason and the position thereof of fault simultaneously.
