1 附 录 ADVISOR Documentation 3.1 ADVISOR file structure 3.1.1 File interactions & data flow The above schematic represents data flow in the ADVISOR file system. The four main agent types are: Input Scripts define variables in the workspace and/or call other input scripts. An example is MC_PM32.M. Block Diagrams are Simulink files containing the equations used to compute outputs such as fuel use from inputs such as an engine map. They are the models. One example is BD_PAR.MDL. Output Scripts post process the model outputs by querying the workspace. These may include plotting routines or error checking routines. chkoutputs.m is an example. Control Scripts may both develop inputs and process outputs. Examples include the ADVISOR GUI and optimization routines. 3.1.2 File locations The main ADVISOR directory (e.g. c:ADVISOR or c:Program FilesADVISOR) contains several sub directories. Among these are the data, GUI, and models directories that contain the corresponding files. 3.1.3 File naming conventions nts 2 All model and data files use a prefix followed by an underscore (_) that is the same as the prefix used for (nearly all of) the variables it defines, which in turn is in pointy brackets ( ESS_*.M Energy storage system data files, which likewise define variables starting with ess_, used in the block labeled EX_*.M Exhaust after treatment files (such as catalysts) FC_*.M Fuel converter data files TX_*.M Transmission data files (these include gearbox-gb and final drive-fd variables) GC_*.M Generator/controller data files MC_*.M Motor/controller data files PTC_*.M Powertrain control data files, which define engine control, clutch control, and hybrid control strategy variables starting with vc_ and cs_, used in blocks labeled and TC_*.M Torque coupler data files VEH_*.M Vehicle data files WH_*.M Wheel/axle data files In addition to the above component data files, there is one other type that nts 3 use prefixes: BD_*.MDL Simulink block diagrams (models) All filenames that include prefixes are entirely in capital letters to avoid confusion with variable names, which are entirely in lower-case letters. 3.1.4 Adding files to ADVISOR The easiest way to add a particular kind of file to ADVISOR is to modify an existing file of that kind and save it with a new file name, entirely in capital letters, in the appropriate ADVISOR directory. This will ensure that all variables necessary to fully define the particular component will be included in your new file. For adding vehicle component or drive cycle files, clicking the pushbutton in the graphical user interface brings up a window to guide the process. 3.1.5 Inspecting input files Component files and nearly all other files in ADVISOR are text files (the exceptions are mat files, which contain Matlab-specific data), and can be viewed and edited in any text editor. A fixed pitch font helps. We recommend using the Matlab editor/debugger packaged with Matlab 5.3. Additionally, text files can be viewed in the Matlab command window by entering type filename at the MATLAB command line. 3.1.6 Deleting files from ADVISORs database Files can be removed from ADVISOR by either deleting them using your operating system or by entering the following at the Matlab command line: !rm filename nts 4 Deleting files via the operating system is preferable, especially on PC and Macintosh platforms, where deleted files will be preserved in Trash or the Recycle Bin. 3.2 Drivetrain model descriptions ADVISOR has six different vehicle types and two specific vehicle choices, as listed below. Each of these has a different drivetrain. There is also an option to use a custom drivetrain. Conventional Drivetrain: The conventional vehicle represents a typical passenger car. It uses only a fuel converter for motive power. The default gearbox is a 5 speed. The conventional accessories are a constant mechanical power load. Series Drivetrain: The series vehicle components include a fuel converter, a generator, batteries, and a motor. The fuel converter does not drive the vehicle shaft directly. Instead, it converts mechanical energy directly into electrical energy via the generator. All torque used to move the vehicle comes from the motor. The default gearbox is a one speed. The default control strategy is a series power follower. The hybrid accessories are a constant electrical power load. Parallel Drivetrain: The parallel vehicle components include an engine, batteries, and a motor. Is is named parallel because both the motor and the engine can apply torque to move the vehicle. The motor can act in reverse as a generator for braking and to charge the batteries. The default control strategy is nts 5 an electric assist. The default gearbox is a 5 speed. The hybrid accessories are a constant electrical power load. Parallel Starter/Alternator: The parallel starter/alternator vehicle components include an engine, batteries, and a motor. It is named parallel starter/alternator because the motor behaves like the starter and the alternator of a conventional vehicle. It allows for engine shutdown and restart and for minimal electric assist. It is a parallel design because both the motor and the engine can apply torque to move the vehicle. The major difference between the parallel starter/alternator design and the basic parallel design is the location of the clutch. The clutch is positioned between the gearbox and torque coupler in the parallel starter/alternator design while it is located between the torque coupler and the engine in the basic parallel design. This means that if the vehicle is moving and the clutch is engage both the engine and motor shafts must be rotating. The motor can act in reverse as a generator for braking and to charge the batteries. The default control strategy is an electric assist . The default gearbox is a 5 speed. The hybrid accessories are a constant electrical power load. Custom:The above figure represents a conventional vehicles drivetrain using components from ADVISOR. Note that most blocks have two inputs and two outputs. Each block passes and transforms a torque and speed request, and each block also passes an achievable or actual torque and speed. The top arrows, feeding left-to-right, are the torque and speed requests. The nts 6 drive cycle requests or requires a given speed. Each block between the driving cycle and the torque provider, in this case the ICE, then computes its required input given its required output. It does this by applying losses, speed reductions or multiplications, and its performance limits. At the end of the line, the ICE fuel converter uses its required torque output and speed to determine how much torque it can actually deliver and its maximum speed. Then passing information back to the left, each component determines its actual output given its actual input, using losses computed during the input requirement pass described above. Finally, the vehicle block computes the vehicles actual speed given the tractive force and speed limit it receives, and uses this speed to compute acceleration for the next time step. And so the cycle continues throughout the duration of the driving cycle. The following describe the torque, speed, and power transformations performed by the drivetrain component models that connected to each other as explained above to build a vehicle model. In addition, the somewhat trickier blocks that perform solely control functions are documented below. 3.2.3 Transmission Torque coupler Torque coupler block diagramRole of subsystem in vehicle Physically, a torque coupler is a three-sprocket belt or chain drive whereby two torque sources combine their torques to provide to a drivetrain component such as the gearbox or final drive. The torque coupler block diagram processes a nts 7 torque and speed request from the downstream drivetrain component and apportions requests of the two feeder torque sources. Description of modeling approach The effects of torque loss and a gear ratio between the second of the torque input devices and the output are modeled here. The torque loss is a constant whenever the torque coupler is spinning. The torque coupler first requests the sum of necessary output torque and torque coupler loss from the first torque source. Using the actual/available torque of the first source, it requests the balance of the second torque source. The speeds of the two torque providers are in constant proportion to the torque coupler output speed: the first input speed equals the output speed, and the second input speed is greater by a factor tc_mc_to_fc_ratio. Gearbox Gearbox block diagram Role of subsystem in vehicle The gearbox of a multi-speed transmission houses gears of different gear ratios that are used to transmit torque from the engine or tractive motor to the final drive and on to the wheels. It thereby allows a number of discrete speed reduction and torque multiplication factors. Inclusion of a gearbox is critical to the drivetrain of conventional and parallel hybrid vehicles, and generally less important for series hybrids. Description of modeling approach The gearbox model in ADVISOR usually communicates physics (torque, speed, nts 8 and power) information to and from the final drive submodel and engine, torque converter, and/or motor model. Control information as might be sensed or commanded by a CPU in the vehicle, such as gear number, is passed to and from the transmission control submodel. Effects on torque and speed in the gearbox include: torque multiplication and speed reduction via the gear ratio, torque loss due to the acceleration of rotational inertia, and torque loss due to the friction of the turning gears. These effects are modeled empirically. Data files such as /data/transmission/TX_5SPD.M are required to supply necessary physical parameters. The equations represented by the Simulink block diagram in the picture corresponding to the link above are as follows. Equations used in subsystem TORQUE AND SPEED REQUIRED (torque reqd into gearbox) = (torque reqd out of gearbox) / (current gear ratio) +(torque reqd to accelerate rotational inertia) + (torque loss due to friction), where (torque reqd out of gearbox) is a Simulink input (#1, in the top left of the above figure) nts 9 (current gear ratio) is computed from (current gear number), which is provided by the gearbox controller interface block, using the look-up vector gb_ratio (torque reqd to accelerate rotational inertia) = gb_inertia * d(speed reqd into gearbox)/dt (torque loss at transmission input due to friction) = function of torque at output-side of gearbox, angular speed at output side of gearbox, gear (e.g., 1st, 2nd, etc.)-this is implemented with a lookup-table (speed reqd into gearbox) = (speed reqd out of gearbox) * (current gear ratio) TORQUE AND SPEED AVAILABLE (torque avail. at output side of gearbox) = (torque avail. at input side of gearbox) * (output side power) / (input side power)required - (torque reqd to accelerate rotational inertia) * (current gear ratio) where (torque avail. at input side of gearbox) is a Simulink input (#2, in the bottom left of the above figure) (output side power) / (input side power)required is computed from the input and output torques and speeds of the REQUIRED calculations (speed avail. at output side of gearbox) = (speed avail. at input side of gearbox) / (current gear ratio) nts 10 nts 11 ADVISOR 使用说明 3.1 ADVISOR的文件结构 3.1.1 文件交互与数据流 ADVISOR 文件系统的数据流如上图所示。图中有四种主要的代表类型： 输入脚本文件定义工作空间的变量或者调用其它输入脚本文件，如MC_PM32.M；模块图表有一些 Simulink文件组成。这些文件含有许多根据输入（如发动机特性图） 计算输出（如燃油经济性）的方程；它们都是一些模型，如 BD_PAR.M.； 输出脚本文件通过搜索工作空间对模型输出作一些后续处理，包括一些画图程序和一些错误检查程序，如 chkoutputs.m。 控制脚本文件既生成输入，也对输出作一些处理。例如 ADVISOR图形用户界面（ GUI）和优化程序。 3.1.2 文件位置 ADVISOR 根目录下（如 c:ADVISOR或 c:Program FilesADVISOR）有一些子目录；这些子目录下是含有相应文件的数据、图形用户界面和模型子目录。 3.1.3 文件命名规则 变
