Functionality of engine start-stop system
The automatic engine start-stop system (MSA) is a fundamental part of the package of measures to reduce CO2 emissions. The reduction in fuel consumption is achieved with the help of the function by automatically switching off the engine when the vehicle is at a standstill. Restarting is also automated as soon as the appropriate switch-on conditions are present.
The automatic engine start-stop function is performed by the engine control unit. Various existing information from the bus system is used for the automatic engine start/stop. Furthermore, additional sensors are necessary for the proper functioning of the automatic engine start-stop system.
