ENGINE TORQUE CONTROL

System Description

INFOID:0000000001162540

The torque structure is the system which translates the driver's request into a torque supplied by the engine. It
is required for certain functions such as the electronic stability program (ESP), the automatic gearbox or the
sequentialgearbox if fitted).
Each inter-system (ESP, automatic gearbox, sequential gearbox) sends the ECM a torque request viathe CAN
communication. The computer arbitrates between the inter-system torque requests and the driver's request
(comprised of the accelerator pedal or the cruise control/speed limiter function). The result of the arbitration
gives thetorque setpoint.
From this torque setpoint, the computer determines the quantity of fuel to be injected (injection duration and
numberof injections) and the amount of air required (turbocharging pressure and EGR rate) so that the engine
is able toprovide the torque required in the best possible conditions (in terms of smooth running performance,
pollutantemissions, etc.).
