An Electronic Control Unit (ECU) is any embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a vehicle. Types of ECU include Engine Control Module (ECM), Powertrain Control Module (PCM), Transmission Control Module (TCM), Brake Control Module (BCM or EBCM), Central Control Module (CCM), Central Timing Module (CTM), General Electronic Module (GEM), Body Control Module (BCM), Suspension Control Module (SCM), control unit, or control module. Taken together, these systems are sometimes referred to as the car's computer (Technically there is no single computer but multiple ones.) Sometimes one assembly incorporates several of the individual control modules (PCM is often both engine and transmission).

Vehicle software download system and method thereof

The present invention relates to a vehicle software download system and a method thereof, in which electronic control unit (ECU) software is downloaded and a corresponding ECU is updated if the version of ECU software stored in memory is lower than the version of ECU software broadcasted from an external apparatus, thereby promptly updating the ECU software installed in the vehicle.
To this end, there is provided a system for updating software of an ECU installed in a vehicle by communicating with an external apparatus having software of the vehicle stored therein, the system comprising: a receiving unit for receiving ECU software version information broadcasted from the external apparatus; a determination unit for comparing ECU software version information stored in a memory with the ECU software version information received through the receiving unit and determining whether or not an ECU software version stored in the memory is lower than a received software version; a download request unit for requesting download of software of a corresponding version from the external apparatus if the ECU software version stored in the memory is lower than the received software version; and a software providing unit for providing the corresponding ECU with the software downloaded from the external apparatus for software update.
