Electronic Throttle System

Electronic Throttle System

the ME 7.2 EMS incorporates an electronic throttle control system. This system comprises three main components:

- Electronic throttle control valve
- Accelerator pedal position sensor (APP)
- ECM.

When the accelerator pedal is depressed the APP sensor provides a change in the monitored signals. the ECM compares this against an electronic "map" and moves the electronic throttle valve via a pulse width modulated control signal which is in proportion to the APP angle signal.

the system is required to:

- Regulate the calculated intake air load based on the accelerator pedal sensor input signals and programmed mapping.
- Monitor the drivers input request for cruise control operation.
- Automatically position the electronic throttle for accurate cruise control.
- Perform all dynamic stability control throttle control interventions.
- Monitor and carry out maximum engine and road speed cut out.
