Information

The engine subsystem interfaces are defined in this sub-package of the VehicleInterfaces library. The engine subsystem has the following connectors some of which are optional (see below for more information):

• accessoryFlange – 1D rotational connection to the accessories subsystem (or other components driven by the engine)
• transmissionFlange – 1D rotational connection to the transmission subsystem
• controlBus – control signal bus connection
• acceleratorPedal – 1D translational connection for the accelerator pedal connection to the driverEnvironment (optional)
• engineMount – MultiBody connection to transmit the engine mount reactions (optional)

The optional connectors are, by default, disabled and can be ignored if not required. They can be enabled by setting the appropriate parameter to be true. This is only possible at design time, i.e. when you are building the subsystem model.

Effects to be modelled in this subsystem

Within the VehicleIntefaces package the engine subsystem is used to model the generation of torque and the application of this torque to the transmission and accessories flange. The connections to the transmission and accessories subsystems are via 1D rotational connectors. The torque reaction in to the engine block and the block itself are also to be modelled in this subsystem if required. The torque reactions, if included, should all be referred back to a single reference frame for the engine block (the engineMount connector).
