AIM: To design a model which detects the vehicle direction using steering wheel input which is compared against traffic signs detected using camera (installed in vehicle in itself) to know whether vehicle is turning/moving in permitted direction or not.   OVERVIEW: Identifying the direction of the vehicle is one of…

AIM: To develop Adaptive Cruise Control (ACC) feature as per requirement document using Simulink.   I. OVERVIEW: 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…

1.Explaination of different types of Lithium ion batteries:           Before learning different types of Lithium ion batteries, let us first look into the construction and working of Lithium ion battery.   Lithium ion battery:  The following figure shows different types of Lithium ion cells depending upon of its shape:…

Objective: To simulate the 3 test cases from harness dashboard for battery management system closed loop model and to write detailed report on the results.   The following figure shows the BMS closed loop model consisting of BMS electronic control unit and plant:   The subsystem of BMS ECU where it mainly…

AIM: To design MATLAB model of electric car which uses a battery and a DC motor.   BLOCK DIAGRAM:  The following block diagram shows the main components used to design the electric car model. The following diagram shows the full model view of electric vehicle model: Drive cycle source enables to choose various…

1).A) Explaination of MATLAB demo model named 'Speed Control of DC motor using BJT H-bridge:           The block diagram of given model designed in the simulink is as shown in the following figure.    Here, motor employed is conventional DC motor (brushed type), so its input supply should…

1).Calculation of braking energy for defined drive cycle: Braking: The action of making a moving vehicle slow down or stop by using a brake or in other way. When vehicle is moving with some velocity, for reducing the speed of the vehicle or to bring the vehicle to rest position, some amount of power is required. So, this…

 1). Types of power converters employed in electric and hybrid electric vehicles: Block diagram of Electric Vehicle:   Power converters used in Electric vehicle : (i) If the motor employed is AC induction motor then 3-`phi` Inverter circuit used between battery and AC motor. The same inverter circuit act as Rectifier…

1).Difference between mapped and dynamic models :   Mapped model:        Mapped model comprises various plots (which may be 2D or may even 3D) between several parameters of the model based on the operating equations of the model. When the model is defined by initial parameters, then whenever input…

1). The interface for ‘EV_defaults_in file’ is as shown in the below figure.   The cargo mass is updated to 500 kgs from bottom right corner as shown in the below image.   After updating cargo mass, click on ‘Continue’ buttton then the window displaying selection for drive cycle is opened…
