Embodiment 1

[0071] The vehicle data processing method provided by the embodiment of the present invention can be applied to terminal devices such as lower computers that acquire vehicle data, such as figure 1 As shown, the vehicle processing method includes:

[0072] Step S101, if it is detected that the vehicle is in the starting or driving state, then respectively send request instructions for acquiring data to the N electronic control units ECUs of the vehicle;

[0073] In the embodiment of the present application, where N≧1 is an integer, when the lower computer is powered on, a communication connection between the ECU in the vehicle and the lower computer can be established to detect whether the vehicle is in the starting or running state. It may be a state in which the vehicle is started but not in motion, and the above state in motion may be a state in which the vehicle is in motion. The aforementioned detecting that the vehicle is in the starting state may be detecting that the v...

Embodiment 2

[0093] This embodiment is a further description of Embodiment 1. For details about the same or similar aspects between this embodiment and Embodiment 1, please refer to the relevant description of Embodiment 1, which will not be repeated here. figure 2 As shown, after the above step S108, it also includes:

[0094] Step S201, if within the Kth preset time after the K-1th data list is sent to the host computer, the Qth Kth data returned by the ECU based on the request command is received; wherein, the Q≧1 and is an integer, K≧3 and is an integer.

[0095] In the embodiment of the application, the K-th preset time for sending the K-1th data list to the host computer may be within the K-th preset time after sending the K-1-th data list to the host computer, or It may be within the second preset time after receiving the last data returned by the ECU for the K-1th time, continue to receive the Qth Kth data returned by the ECU.

[0096] Step S202, use the Q-th K-th data as the K-...

Embodiment 3

[0106] This embodiment is a further description of Embodiment 1 or Embodiment 2. For the same or similar aspects between this embodiment and Embodiment 1 or Embodiment 2, please refer to the relevant descriptions of Embodiment 1 or Embodiment 2, and will not repeat them here. ,like image 3 As shown, the above step S103 includes:

[0107] Step S301, using the M first data as M first key values, and judging whether the types of request instructions associated with the M first key values ​​are different.

[0108] In the embodiment of the present application, the above request instruction associated with the first key value can be understood as: according to which type of request instruction the first data corresponding to the first key value is returned. If the first data corresponding to the first key value is the first data returned according to the request instruction for obtaining vehicle speed data, then the request instruction type associated with the first key value is t...

Abstract

The invention belongs to the technical field of vehicles, and provides a vehicle data processing method and device, and the method comprises the steps: receiving M pieces of first data returned by anECU within a first preset time; Taking the M pieces of first data as first key values and configuring corresponding key value names, and taking the first key values and the correspondingly configuredkey value names as first key value pairs and storing the first key values and the correspondingly configured key value names into a first data list; If I pieces of second data are received within second preset time, taking the I pieces of second data as second key values, configuring corresponding key value names, and storing the second key values in a second data list; Judging whether a second key value pair with the same key value name and different key values in the first data list exists in the second data list or not; And if yes, sending a second key value pair with the same key value name and different key values in the first data list to the upper computer. The data transmission efficiency of the lower computer can be improved, the power consumption of the lower computer is reduced,and meanwhile the working efficiency of the upper computer can be improved.

Description

technical field [0001] The present application belongs to the technical field of vehicles, and in particular relates to a vehicle data processing method and device. Background technique [0002] With the development of vehicle electronic control technology, various data of vehicle operation can be obtained after communicating with various electronic control units (Electronic Control Unit, ECU) inside the vehicle through the lower computer (such as vehicle diagnostic equipment, etc.), and the acquired Various data are sent to the host computer (such as mobile terminal, notebook or palmtop computer, etc.), and the host computer analyzes the various data to diagnose vehicle faults. [0003] However, in the current diagnosis method for vehicle faults, the lower computer transmits various vehicle operation data obtained by communicating with each ECU inside the vehicle to the upper computer in real time, which consumes a lot of power and the data transmission efficiency is low. ...
