Common use of Block Diagram Clause in Contracts

Block Diagram. The battery provides the high voltage to drive the FEV. The High Voltage Junction Box is distributing the energy to different consumers or providers. The main consumer is the drivetrain, consisting of power electronic and e-machine. But there are others as heater or compressor. These consumers are not part of this model. The energy is provided by a charger. There might be different chargers connected to the high voltage junction box. They are not modeled either. The Electric Vehicle Controller is the main controller for many powertrain functions of an electric vehicle. As an electric vehicle does not need gears for transmission there is no need for a transmission box. But the vehicle has to be able to change direction forward and backward. Furthermore it has to be possible to bring the vehicle in a parking mode. That is why a Driving Mode Selector (PR(N)D) with at least 3 buttons is necessary. To accept a certain indication for a driving mode the brake signal and the actual speed have to be evaluated. All these components and their interaction possibilities are described in the following two figures. • Figure 2 shows an implementation with hard wired signals between EVC, HVJB and battery. • Figure 3 shows another implementation of the same system with CAN connectors on all three components.
