Remote maintenance method of automotive electronic control unit based on cloud

Abstract

The present invention relates to the field of automobile control, in particular to a cloud-based remote maintenance method for automobile electronic control units, comprising the following steps: 1) establishing a database of automobile electronic control units in the cloud; Collect the running data of the car; 3) The on-board T‑BOX reads the running data stored in the car ECU and uploads it to the cloud-based car ECU database; 4) The manufacturer of the car ECU calculates the vehicle ECU 5) The manufacturer of the automotive electronic control unit uploads the calibration parameters to the cloud-based automotive electronic control unit database for storage; 6) After the vehicle’s on-board T‑BOX receives the command to modify the parameters from the cloud , receiving the calibration parameters of the manufacturer of the vehicle electronic control unit, and overwriting the previous parameters of the vehicle electronic control unit, and adjusting the vehicle to the best performance matching state.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a cloud-based remote maintenance method for an automobile electronic control unit. Background technique [0002] Automotive electronic control unit ("ECU" for short) is a particularly important functional device in a car. All cars need to be calibrated for ECU parameters before leaving the factory, so that the matching of each link controlled by the ECU can achieve the best performance. At present, the parameter calibration of ECU is usually that the vehicle manufacturer sends the whole vehicle that is about to leave the factory to the ECU manufacturer for parameter calibration of the ECU, and then leaves the factory after calibration, resulting in high vehicle transportation costs. Moreover, once the vehicle breaks down during the transmission, it cannot be repaired in time, which will affect the calibration operation of the faulty vehicle, and cannot guarantee the normal opera...

AI Technical Summary

Problems solved by technology

At present, the parameter calibration of ECU is usually that the vehicle manufacturer sends the whole vehicle that is about to leave the factory to the ECU manufacturer for parameter calibration of the ECU, and then leaves the factory after calibration, resulting in high vehicle transportation costs.

Moreover, once the vehicle breaks down during delivery, it cannot be repaired in time, which will affect the calibration operation of the faulty vehicle, and cannot guarantee the normal operation of the parameter calibration of the vehicle ECU.

[0003] On the other hand, there may be problems that the ECU manufacturer has not detected in the vehicle during the development stage and the owner's use stage. Once these problems cause the vehicle to malfunction, in order to correct these problems, the vehicle needs to be returned to the vehicle manufacturer for maintenance. Or the vehicle manufacturer and ECU manufacturer send people on business trips to the site for maintenance, which greatly increases the maintenance cost
