Problems solved by technology

[0004] In view of related technologies, in the vehicle-mounted system, when the application program in the ECU needs to be updated, the ECU needs to be disassembled from the vehicle and reprogrammed, and it is impossible to update the application program in the ECU online. At present, no effective problem has been raised. The present invention, for this reason, the main purpose of the present invention is to provide a kind of refreshing method and system of application program, to solve the above-mentioned problem

Abstract

The invention discloses a method and a system for refreshing an application program. The method comprises the following steps that: an electronic control unit acquires a reprogramming instruction from a downloading tool; the electronic control unit enters a reprogramming mode according to the reprogramming instruction; and the downloading tool downloads a new application program and storing the new application program to the electronic control unit. By the method, the electronic control unit (ECU) application program can be reprogrammed on line.

Description

technical field [0001] The invention relates to a method and system for refreshing an application program. Background technique [0002] On today's motor vehicles, multiple electronic control units (ECUs) are often installed to perform different functions. These control units include the body control module (BCM), which is mainly used to control the lights, doors, windows and anti-theft parts of the car body; the engine controller, which is mainly used to control the injection quantity delivered to the engine cylinder or Intake airflow control; also includes navigation system and diagnostic system, etc. These ECUs are usually connected together through a vehicle-mounted network bus system, such as CAN bus or LIN bus, for coordination and information sharing among them. These ECUs usually include a processor and external devices (such as: communication transceivers, off-chip memory, etc.), and the ECU application program is stored in the internal memory of the processor or ...
