Abstract
The utility model relates to a vehicle driving data recorder, which can record data according to requirements, no needing external wire harness. The technical scheme is that the vehicle driving data recorder comprises an M C U, which is characterized in that the M C U is connected with a C A N driving unit circuit, and is further connected with a U S B interface circuit. The utility model can record large data size, can select data to record according to actual requirements, and can record the inner parameters of control systems such as T C U, E C U, thereby being used to accurately position the driving failures.
Description
Technical field
The utility model relates to a kind of vehicle-mounted driving datalogger.
Background technology
Visible driving datalogger on the market is merely able to write down information such as some speed mileages, can't be when automobile breaks down the reason of accurate fault location.The drive recorder of more complicated requires the extraneous many sensors of register instrument, has increased the car load wire harness like this, brings negative effect may on the contrary the security of car load.
The utility model content
Goal of the invention of the present utility model is to provide a kind of vehicle-mounted driving datalogger, record data as required, and need not external wire harness.
Realize the technical scheme of the present utility model purpose:
A kind of vehicle-mounted driving datalogger has single-chip microcomputer, it is characterized in that: single-chip microcomputer connects CAN driver element circuit, and single-chip microcomputer also connects usb circuit.
The beneficial effect that the utlity model has:
The utility model is equivalent to original car load high-speed CAN network increases a node, thereby realizes the collection and the record of various data.The data volume that can write down is big, data that can not select the person to write down according to the actual needs, and can write down the inner parameter of TCU, ECU dispatch control system, can help us accurately to locate driving faults like this.And the utility model has also solved calibration experiment needs notebook, and the problem that requires many people to participate in simultaneously.
Description of drawings
Accompanying drawing is the utility model circuit principle structure block diagram.
Embodiment
As shown in the figure, single-chip microcomputer (selecting the MC9S12 processor for use) connects CAN driver element circuit, and CAN driver element circuit inserts the CAN network of car load, and single-chip microcomputer also connects usb circuit (selecting CH375 for use).
Single-chip microcomputer can also be circumscribed with data display circuit.
Single-chip microcomputer can also be circumscribed with storage unit circuit (selecting the FLASH storage chip for use), connects the level conversion unit circuit between single-chip microcomputer and the storage unit circuit.
Single-chip microcomputer is realized reading of data by car load CAN network, and the computer expert crosses USB interface and realizes reading of data.
