Problems solved by technology

Since the current OBD interface is powered by constant power (normal power refers to the positive power that is connected from the positive pole of the vehicle’s battery and is not controlled by any switches, relays, etc.), therefore, even if the vehicle is turned off, the OBD interface will still be in the power state. Under the control of the bare metal program, the OBD data will continue to be obtained through the OBD interface, resulting in unnecessary waste of power consumption
If you want to stop the acquisition of OBD data, you can only disconnect the power supply line of the OBD interface, but ordinary users do not know how to disconnect the power supply line of the OBD interface at all.

Abstract

The invention discloses a method for processing vehicular diagnosis data. The method includes creating vehicular diagnosis tasks when vehicular operating systems of vehicles are started; acquiring the vehicular diagnosis data of the vehicles in real time under indication of the vehicular diagnosis tasks; stopping acquiring the vehicular diagnosis data of the vehicles when the vehicular diagnosis tasks are cancelled. The invention further provides a corresponding device for processing the vehicular diagnosis data. According to the scheme, the method and the device have the advantage that the vehicular diagnosis data acquisition flexibility can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a processing method and device for on-board diagnostic data. Background technique [0002] On-Board Diagnostic (OBD) system is an on-board terminal that can monitor the operating status of the engine and the exhaust gas treatment system at any time. OBD data includes the engine, catalytic converter, particulate filter, oxygen sensor, emission control On-board diagnostic data obtained when monitoring the fuel system, fuel system, exhaust gas recirculation (EGR, Exhaust Gas Recirculation), etc. [0003] The existing OBD system is written by a bare-metal program, so as long as the OBD interface is powered on, the OBD interface will obtain OBD data under the control of the bare-metal program. Since the current OBD interface is powered by constant power (normal power refers to the positive power that is connected from the positive pole of the vehicle’s battery and is not controlled ...
