Highway Assistant – Lane Changing Assistant Highway Assistant is a partially automated driving function for a speed range of up to 180 km/h (112 mph) on highways. It combines the radar-based longitudinal guidance of Adaptive Cruise Control (ACC) with the video-based lateral guidance of lane keeping support in one…

Objectives: To develop one specific requirement of Traffic Jam Assistant algorithm which would predominantly feature in the IPC algorithm. To develop Simulink model as per MBD requirements, Code Generation Profile in Embedded Coder, create Simulink Data Dictionary and generate Model Advisor Report…

Adaptive Cruise Control(ACC) Adaptive Cruise Control Feature for passenger cars allows the host vehicle to adapt to the speed in line with the flow of traffic. Driving in heavy traffic or keeping a safe distance to the preceding vehicle calls for a high level of concentration. The Adaptive Cruise Control feature can reduce…

Objective: To identify the direction (Left turn, Right turn and Straight) based on the camera input and to determine whether car is going in correct direction or not. To develop the Simulink model according to requirements with SLDD according to MAAB guidelines and generate C code.    Steps: Create the SLDD(Simulink…

Project: 10 cell series lithium ion battery model A simple thermal model is used to model battery temperature. It is assumed that cooling is primarily via convection, and that heating is primarily from internal resistance. A battery pack can be modeled by connecting multiple copies of the battery cell block in series.…

Objective: Battery pack drawing along with its enclosure.  Given:  Cell: ANR26650M1-B Battery pack capacity: 18 kWh ANR26650M1-B: A123’s high-performance Nanophosphate® lithium iron phosphate (LiFePO4) battery technology delivers high power and energy density combined with excellent safety performance and extensive life…

Inside BMS_ClosedLoop subsytem; there is BMS ECU and plant as shown below: Inside BMS ECU system:…

1.Materials & chemical reactions of lithium ion cells A battery is made up of several individual cells that are connected to one another. Internal connection of battery: It contains five components: positive electrode (a cathode), negative electrode (an anode), liquid electrolyte,…

Project: MATLAB model of electric car which uses a battery and a DC motor: Objectives:   System level configuration  Model parameter  Results  Conclusion Solution: An electric car is an automobile that is propelled by one or more electric motors, using only energy stored in batteries.…

6. a) To calculate the force and power required to push / pull an aircraft by a towing vehicle: Although aircrafts are quite capable of moving themselves forwards or backwards on the ground using their own engines for thrust, that is not allowed because - the resulting jet blast or prop wash would cause increased noise…

1. a) Driving cycle: Driving Cycle:A series of data points representing the speed of a vehicle versus time. Driving cycles are produced by different countries and organizations to assess the performance of vehicles in various ways, as for instance fuel consumption, electric vehicle autonomy and polluting emissions.…

1. A.  MATLAB demo model ‘Speed control of a DC motor using BJT H-bridge’: Model Link BJT H-bridge used to generate a chopped voltage and to control the speed of a DC motor. Description: Pulse Width Modulation (PWM) is a popular technique used to control the speed of a DC motor by controlling…

1. Types of power converter circuits are employed in electric and hybrid electric vehicle: DC-DC Converter: Converts the unregulated DC input to regulated DC input. Non-isolated Converter:-The input and output are ohmically connected, most often having the negative side in common. We can measure low ohms between some of…

What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  Solution: Dynamic models describe processes that have a memory, or more formally processes for which the state at a given time depends on the states and inputs at previous times. These models are…

1.   For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations. Solution: Firstly extracted the Downloaded file into MATLAB directory and then add to path. Type 'advisor' in command window as shown below:…

Implement control logic of a “washing machine” using State flow as per given sequence:  If the power supply is available, the system gets activated  If the Water supply is not available, stop the process & indicate through LED Soaking time should be 200s followed by washing time of 100s. Then…

Problem Statement: Make a Simulink model of Doorbell using solenoidblock with the following details: In the above arrangement, when the switch is closed the electromagnet receives electrical power from the battery and pulls the metal arm to hit the bell producing sound.  Create a situation where the switch is…
