Project 1- Traffic Jam Assistant Feature
OBJECTIVE
- This model must be developed in MATLAB Simulink as per MBD guidelines.
- Code Generation Profile must be in Embedded Coder.
- Simulink Data Dictionary must be created for the model & must be linked to the model.
- Model Advisor Report is mandatory & this will be followed by Code Generation.
Traffic Jam Assistant Feature
Traffic Jam Assistant is based on the sensors and the functionality of the Adaptive Cruise Control (ACC) with stop & go and Lane Keeping Support (LKS). When ACC ‘Stop & Go’ is turned ON, the Traffic Jam Assistant continuously analyses the speed of the surrounding vehicles and compares it with the own driving speed. If the system detects dense traffic or a traffic jam at speeds less than 60 kmph, the driver can activate the functionality by press of a button. The vehicle will now automatically follow the vehicle in front, takes over driving off, acceleration, braking and steering within same lane.Information regarding the Traffic Jam Assistant will be available to be displayed to the driver in the Instrument Panel Cluster (IPC). The Algorithm which the students need to implement here in this project is predominantly based on IPC unit
ŠKODA Superb – Traffic Jam Assist
Requirement No 1:
- Input Signal “Input_Voltage” is compared against voltage values “VOLTAGE_MINIMUM_RANGE” & “VOLTAGE_MAXIMUM_RANGE”.
- Incoming input signal “Input_Voltage” must be greater than – equal to “VOLTAGE_MINIMUM_RANGE” and less than – equal to “VOLTAGE_MAXIMUM_RANGE”.
- Output signal from here is “Optimum_Voltage” which will be one of the inputs to the subsystem “DisplayUnit”.
Requirement No 2 (DisplayUnit Subsystem):
- Input Signals are “Optimum_Voltage”, “Input_Switch”,“Enable_Display”. Signal “Enable_Display” must be saturated between the range 0 – 7. Output signal from the subsystem is “Output_Display”.
- Input Signal “Enable_Display” is compared against pre – defined set of values in a multiport switch. Total data ports in the multiport switch is 5.
- Multiport switch inputs 1 & 2 is connected to calibration signal “ON_MODE”, Multiport switch inputs 3 & 4 is connected to calibration signal “OFF_MODE” while Multiport switch input 5 is connected to calibration signal “STANDBY_MODE”.
- The output from Multiport switch is connected to the first input port of the Switch block. The third input port of the Switch block is connected to the calibration signal “NO_DISPLAY”.
- Meanwhile NOT value of input signal “Input_Switch” is compared in an AND gate against input signal “Optimum_Voltage” and the output from comparing if calibration signals “INTERRUPT_1” & “INTERRUPT_2” are equal. The output of the AND gate is the second input of the switch block.
- The output from the switch block is “Output_Display”.
Requirement No 1 and 2 we created as subsystem
configuration parameters
Simulink Data Dictionary must be created for the model
Model Advisor Report for the model
Code Generation.
conclusion
as per the given requirement we created a model and sldd,mab report,c code files are submitted in this project
