powertrain control

Today's powertrain control systems include advanced ECU functionality, multiple interfaces with other vehicle systems, sophisticated control strategies and advanced sensors and actuators. Alongside ever more stringent emission legislation for both gasoline and diesel, these demands drive a requirement for well documented process and the use of the latest tools for DoE and model based calibration. IP's range of robust and effective solutions for engine calibration have been proven on numerous OEM production programmes. Our techniques support client demand for compressed timing, very high quality solutions and reduced testing requirements for minimum cost.

IP's testing facilities include a vehicle emission test facility, jointly owned with Tickford Powertrain Test. The emission facility includes independent Horiba modal analyser systems for gasoline and diesel, and mass particulate measurement systems. The facilities have been used on many of IP's production sign off programmes for EU5/6 and ULEVII, and are regularly correlated with client facilities. Cold ambient (eg -7 C) soak development tests can also be conducted within the facility.

IP also carries out engine and vehicle instrumentation for calibration and other programmes at its main Milton Keynes site, where there are also static cold chamber facilities. Engine dyno test facilities leased from our testing partners are used for engine mapping, including motoring and transient cycle development.
