Common use of Vehicle level Clause in Contracts

Vehicle level. ‌ The main feature of a fully electric vehicle (FEV) is the using of high voltage electrical energy for driving, provided by a battery. 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. It has to be assured that no one touches high voltage unintentionally. Furthermore it is important to supervise the proper function of all high voltage connections. For this reason the interlock line is established. That is every high voltage connector has two additional contacts which are connected to each other as long as the connector is plugged in completely. As soon as one connector is released the interlock is opened. When this occurs the high voltage supply is disconnected immediately. This function is required to assure that persons do not have contact to the high voltage under all circumstances. Maybe a connector is damaged after an accident. Then the high voltage supply has to be stopped to avoid any further damage of persons. It is dangerous to stop the emachine in case the interlock line was opened by mistake. If this happens during a takeover maneuver the vehicle will lose driving energy immediately. As the Electric Vehicle Controller is the main controller for many powertrain functions of an electric vehicle. It provides the information to feed the interlock line to the HVJB. This is done by a dedicated signal on the connection Feed interlock between EVC and HVJB. Thus the EVC is the beginning of the interlock line. Furthermore the EVC is then the endpoint of the interlock line – connection Evaluate interlock between HVJB and EVC. In the EVC the evaluation of the status of the interlock line is done. As a result of this evaluation the EVC may decide to shut down the high voltage which is done with the connection PowerSourceEnable and to stop the torque request from the Powerelectronic.

Figure 2-1: Vehicle Feature Model of the “Propulsion” subsystem As described in previous chapter, the EV has to be able to change direction forward and backward electrically. Furthermore it has to be possible to bring the vehicle in a parking mode. That is why a Driving Mode Selector (PRND) is necessary. To accept a certain indication for a driving mode by the driver the brake signal, the speed and e-propulsion status of the vehicle have to be evaluated. The gears PRND are set according to the drivers wish and status (velocity and status of propulsion and brake). The Torque control needs to know the status of the selected Driving mode to
