Abstract
The utility model relates to a software updating device of a speed changing box control unit, which can timely update the software of the speed changing box control unit. The technical scheme is as follows: the software updating device comprises a USB (universal serial bus) chip and a CAN (controller area network) chip; and the software updating device is characterized in that a signal output end of the USB chip is connected with the CAN chip, while the signal output end of the CAN chip is connected with the speed changing box control unit.
Description
Technical field
The utility model relates to a kind of software refreshing device of wheel box control module.
Background technology
Automatic gearbox of vehicles needs on stream according to the demarcation situation to wheel box, and the software to the wheel box control module refreshes often, in after market, when software version need be upgraded, also needs controller is refreshed.
With the maximally related prior art of the utility model be that denomination of invention is " memory device of software refreshing and method " patent (patent No.: 03824507.8) disclosed technical scheme, but the software refreshing device at the wheel box control module still belongs to blank, causes in time finishing related work.
The utility model content
Goal of the invention of the present utility model is to provide a kind of software refreshing device of wheel box control module, can realize in time refreshing to the software of wheel box control module.
Realize the technical scheme of the present utility model purpose:
A kind of software refreshing device of wheel box control module comprises USB chip and CAN chip, and it is characterized in that: the signal output part of USB chip connects the CAN chip, and the signal output part of CAN chip connects the wheel box control module.
The USB chip is connected to eeprom chip.
The USB chip is connected to the LED lamp.
The signal output part of CAN chip connects the wheel box control module through wave filter.
The beneficial effect that the utlity model has:
The utility model USB chip receives and handles the data that computer transmits, and by the CAN chip data is converted to CAN information, is sent to the wheel box control module by the CAN network, can realize the software refreshing of wheel box control module effectively in time.
Description of drawings
Accompanying drawing is a schematic block circuit diagram of the present utility model.
Embodiment
As shown in the figure, comprise USB chip U1 and CAN chip U2, the signal output part of USB chip connects the CAN chip.USB chip U1 is connected to eeprom chip U3, and the USB chip is connected to LED lamp D1, D2, and the signal output part of CAN chip U2 connects the wheel box control module through wave filter L by the CAN line.
The signal input part of USB chip U1 meets the USB of computer, and USB chip U1 receives and handles the data that the computer USB mouth sends, and eeprom chip U3 is used for storage data, and when USB chip U1 read data, LED lamp D1 lights, and does not stop flicker; As USB chip U1 during prior to CAN chip U2 write data, LED lamp D2 lights, and does not stop flicker.CAN chip U2 becomes CAN information to be sent to the wheel box control module by the CAN line data-switching, realizes software refreshing, and wave filter L can prevent to be subjected to the signal interference after the utility model from inserting car load CAN network.
