Many systems in cars can be assumed to be speed dependent. The pin on the left must be connected to the speed of the car or engine. This load represents a constant power load, which could be switched between peak, permanent, and off power. The switch sequence is determined by the appropriate user profile, which is used for different drive cycles. This load models a multi-level load like a fan.
Some loads are very complex to model yet their behavior is easily measured.
This template reads in a measurement of power, resistance, or current vs. time as its input. It could be used for the generic base load in a vehicle. A power window system is a typical mechatronic load in a car. It includes a motor to drive the window mechanics and electronics to control the motor current and to switch off the system when the window has reached the uppermost position. Furthermore it incorporates software for the bounce back algorithm and reads in a user profile.
