Abstract

The invention provides a vehicle body controller firmware upgrading method, terminal and system. The upgrading method comprises the steps of enabling a vehicle-mounted terminal to obtain and receive to-be-upgraded firmware information sent by a cloud server; downloading a firmware upgrade package according to the to-be-upgraded firmware information; and flashing firmware corresponding to the firmware upgrade package according to the firmware upgrade package, and carrying out firmware upgrade. ECU / BCM firmware in the vehicle is upgraded online. Online upgrading of large-scale vehicles can be met, manpower and time investment is reduced, the ECU / BCM firmware upgrading cost is reduced, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle equipment, and relates to a method for upgrading firmware, in particular to a method, a terminal and a system for upgrading firmware of a vehicle body controller. Background technique [0002] At present, automobile manufacturers often need to upgrade the ECU (Electronic Control Unit, Electronic Control Unit) of the vehicle during vehicle recall and technology update; ECU upgrade (Electronic Control Unit), also known as refresh ECU or ECU tuning, mainly through rewriting The method of program is to fine-tune the fuel supply and ignition on the basis of the original factory data, optimize parameters, etc. to achieve the purpose of increasing output horsepower, increasing torque or reducing fuel consumption; since the essence of ECU is a driving computer, once the ECU upgrades wrong, it will It brings great hidden dangers to driving safety, so it is necessary to ensure the safety, reliability and ac...
