DETERMINING WHETHER TO INSTALL A VEHICLE SYSTEM UPDATE IN A VEHICLE

A software update system for a vehicle is disclosed, as well as a method of determining whether to install a software update at an electronic control unit (ECU) in the vehicle. The method includes the steps of: receiving at the ECU a first signal from a first vehicle system module (VSM) in the vehicle; receiving at the ECU a second signal from a second VSM in the vehicle, wherein the first and second signals each provide an indication that the vehicle is in a stationary state; based on the first and second signals, assessing at the ECU that the vehicle is in the stationary state, wherein the assessment is in accordance with a first predetermined confidence level; and in response to the assessment, authorizing at the ECU an installation of the software update on ECU memory.
