Abstract
The invention relates to a diagnosis tool of a motor vehicle, in particular to a diagnosis communication system of a trip computer of a motor vehicle. The diagnosis communication system, which is applied to motor vehicles, comprises a trip computer, a control terminal and a signal emitting and receiving unit. The control terminal, which is in communication connection with the trip computer via the signal emitting and receiving unit, sends control instructions to the trip computer so as to obtain data stored in the trip computer and conducts diagnosis of the motor vehicle according to the data. According to the invention, the signal emitting and receiving unit is wirelessly connected by a smart phone or a flat computer, the trip computer of an automobile or a motorcycle is connected by the signal emitting and receiving unit, and the trip computer is controlled by an APP in the smart phone to conduct data refreshing, diagnosis, vehicle inquiry and vehicle running information inquiry. Due to the fact that the trip computer is controlled only by adopting the APP instead of special diagnosis devices, the cost for original diagnosis devices, refreshing tools, instrument boards and the like is reduced. In addition, an ECU is wirelessly controlled by the APP, thereby eliminating the distance limitation.

Owing to only adopting APP to control car running computer, notThere is employing dedicated diagnostic device, can reduce original diagnostic device, refresh tool, instrument board etc.Cost, and APP controlled in wireless ECU, be not subject to distance limit.
Brief description of the drawings
Fig. 1 is the system schematic of the diagnosis communication system of a kind of car running computer of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as thisThe restriction of invention.
A diagnosis communication system for car running computer 1, is applied in motor vehicle, comprises driving electricityBrain 1 (being inside located in motor vehicle), control end 3 and signal receiving/transmission device 2. Control end 3 is intelligenceThe APP establishing in energy mobile phone or panel computer, signal receiving/transmission device 2 is Dongle 2. APPCommunicate to connect car running computer 1 by the Dongle 2 that connects car running computer 1, APP sendsControl instruction is to car running computer 1 and obtain the data that car running computer 1 is stored, and according to obtainingData are diagnosed vehicle. Dongle 2 wireless telecommunications connect APP, Dongle2 connect car running computer 1 by CAN bus or K line. Dongle 2 is a kind of drivingsConnecting bridge between computer 1 and APP, it is connected with the OBD port of car running computer 1,And carry out communication by bluetooth or WIFI. APP sends to the control instruction bag of car running computer 1Draw together diagnostic instruction, refresh data instruction, vehicle query instruction and vehicle traveling information query statement.Diagnosis refers to by the parameter result of car running computer 1 and judges its residing state, whether has parameterExceed standard etc. Refresh data refers to and can carry out the software of engine electric-controlled unit and nominal dataRefresh and upgrade. Vehicle query instruction comprise GPS information to vehicle, vehicular applications instruction,The inquiry of analyzing after sale. Vehicle traveling information query statement comprises the speed of a motor vehicle, mileometer, averageThe inquiry of oil consumption, course expense, driving time, moment of torsion and power.
