Abstract

The invention discloses a data reading method and device, terminal equipment and a storage medium, the data reading method is applied to a gateway of a vehicle, the method comprises the following steps: receiving target data sent by an ECU, the target data being sent by the ECU when a preset condition is satisfied; and storing the target data, and sending the target data to a target device after receiving a data reading instruction sent by the target device, the gateway of the vehicle being in communication connection with the target device. According to the method and the device, the target data from the ECU is stored in the gateway of the vehicle, so that the target equipment can directly read the target data stored by the target equipment from the gateway, and the target data is sent by the ECU when a certain condition is met, so that data interaction between the gateway and the ECU is reduced, and the problem of data transmission delay caused by overhigh automobile bus load is solved.

Description

technical field [0001] The present application relates to the technical field of automobile diagnosis, and in particular, to a data reading method, device, terminal device and storage medium. Background technique [0002] Nowadays, the degree of intelligence and informatization of automobiles is getting higher and higher. The composition of automobiles contains many electronic components. When the automobile fails, technicians need to check the fault point from the complex automobile structure. To this end, car diagnostic technology is also developing continuously. By using the target equipment of car diagnosis to read and analyze various target data of the car, the fault point can be accurately and quickly found so that technicians can repair the fault point. [0003] In the process of reading the target data of the car in the existing car diagnosis technology, the target device of the car diagnosis first sends the target data reading command to the gateway of the vehicle, ...
