Project 2-Highway Assistant-Lane Changing Assistant

PROJECT - 2

Highway Assistant-Lane Changing Assistant

• The Highway Assistant supports the driver and takes over the longitudinal and lateral guidance of the vehicle in monotonous driving situations on highways.
• The partially automated function can automatically start, accelerate, brake as well as steer the vehicle to a certain extent. The driver has to permanently supervise the system and be ready to take over the complete control of the vehicle at any time.

• To understand this project better , i have simplified it in the forms of steps
• Take a look at it .

1) MODEL DEVELOPEMENT :

• This is upper phase of the model .
• In order to simplify the model , i have sub systems for it .

• So these are 2 sub systems for 2 different requirement .
• Lets see each of them in detail

• So this is req 1 model blocks
• Also same as it is there is a model 2 req
• The difference between them is variable name
• The conditions involved in the stateflow

• This is req 3
• The involvement of switch blocks are there into it .

2 ) Now SLDD creation :

• After making of the logic , craete a SLDD file in which all the variables and the signals names are mentioend in detail . Not doing this will not run the simulation .

3) ENABLE SIGNALS :

• This is done to ensure that the signal information mentioned in SLDD file is complied with the actual signal in the model for the perfect information flow .

4) REQUIRMENT TAGGING :

• This is done to understand the logic in words which is mentioned for the particular sub sytem .
• For this we need to create the requiements in the word file and then we have to tag it with the model .

6 ) MODEL SETTINGS

• Do the model setting for the proper run of the advisory report and the code generation so that thre there are minimum warnings .

• First of all , change the target file to AUTOSAR.tlc . in the code generation settings of confifuration settinngs .
• This is done to ensure that the envinment of the model will change to the autosar format .

7 ) AUTOSAR SETTINGS

• The first option that has to be configured is the XML option
• All the the input settings are done as per the figure .

• Now after doing this , we have to Edit the reciever ports names with the prefiX Rp_
• This is done for each and every input

• Now after doing this , we have to Edit the sender ports names with the prefiX Pp_
• This is done for each and every output

• Now after XML , we have to edit this by adding a prefix called SRIf with each name
• After doing it save them .

• Now after doing this , we have to check on the code mapping option .
• This is done For checking weather the updated value untill now are being properly mapped or not
• This is done for both input and outputs.

8) ADVISORY CHECK :

9) Final CODE GENERATION :
