Project 2-Highway Assistant-Lane Changing Assistant
PROJECT 2: HIGHWAY ASSISTANT - LANE CHANGING ASSISTANT
Aim:
Implementing the Highway Assistant Lane changing assiatant by understanding the given requiremnts.
Objective:
- Model must be developed in MATLAB Simulink per MBD guidelines.
- Code Generation Profile must be AUTOSAR Coder.
- Simulink Data Dictionary must be created for the model & must be linked to the model.
- All the input & output signals must be mapped into the Autosar Editor.
- Model Advisor Report is mandatory & this will be followed by Code Generation.
Requirements:
Requirement No 1 [Highway_DisplayUnit]:
Inputs to this particular subsystem are “Highway_Input_Signal”, “Enable_Display”, “Input_Switch”. These three input signals, when assigned to a particular value will give output signals of specific value. The output signals are “Highway_Display_Mode_1”, “Highway_Display_Mode_2”, “Highway_Display_Mode_3”, “Highway_Display_Mode_4”. The requirement must be implemented in the form of a Stateflow logic.

Highway_Display_Mode_1 = 213 Highway_Display_Mode_2 = 183 Highway_Display_Mode_3 = 9 Highway_Display_Mode_4 = 94 |
Subsystem (Highway_DisplayUnit):
Requirement No 2 [Lane_DisplayUnit]:
Inputs to this particular subsystem are “Enable_Display”, “Input_Switch”, “Lane_Input_Signal”. These three input signals, when assigned to a particular value will give output signals of specific value. The output signals are “Lane_Display_Mode_1”, “Lane_Display_Mode_2”, “Lane_Display_Mode_3”, “Lane_Display_Mode_4”. The requirement must be implemented in the form of Stateflow logic.

Lane_Display_Mode_1 = 127 Lane_Display_Mode_2 = 248 Lane_Display_Mode_3 = 186 Lane_Display_Mode_4 = 84 |
Subsystem (Line_DisplayUnit)
Requirement No 3:
Signals coming from both subsystems “Highway_Display_Mode_1” & “Lane_Display_Mode_1” are given as inputs to a switch block which will have input signal “Highway_Input_Signal” given as 2nd input to the switch block. Corresponding output from this particular switch block is output signal “Display_Mode_1”.
Signals coming from both subsystems “Highway_Display_Mode_2” & “Lane_Display_Mode_2” are given as inputs to a switch block which will have input signal “Highway_Input_Signal” given as 2nd input to the switch block. Corresponding output from this particular switch block is output signal “Display_Mode_2”.
Signals coming from both subsystems “Highway_Display_Mode_3” & “Lane_Display_Mode_3” are given as inputs to a switch block which will have input signal “Highway_Input_Signal” given as 2nd input to the switch block. Corresponding output from this particular switch block is output signal “Display_Mode_3”.
Signals coming from both subsystems “Highway_Display_Mode_4” & “Lane_Display_Mode_4” are given as inputs to a switch block which will have input signal “Highway_Input_Signal” given as 2nd input to the switch block. Corresponding output from this particular switch block is output signal “Display_Mode_4”.
