Vehicle-to-Vehicle (V2V) safety in EV Technology - Mini Project: Build & Apply

Vehicle-to-Vehicle (V2V) Safety Basics

📖 Scenario: You are part of a team developing educational material to explain how Vehicle-to-Vehicle (V2V) communication helps improve road safety. Your goal is to build a simple data model that represents vehicles and their safety messages exchanged in real time.

🎯 Goal: Create a basic data structure to represent vehicles and their V2V safety messages, configure a safety distance threshold, apply logic to identify vehicles too close to each other, and finalize the setup to simulate a safety alert system.

📋 What You'll Learn

Create a dictionary named vehicles with vehicle IDs as keys and their current speeds (in km/h) as values

Add a variable named safety_distance to represent the minimum safe distance between vehicles in meters

Use a loop with variables vehicle_id and speed to check which vehicles exceed a speed threshold and might need alerts

Add a final configuration variable named alert_enabled set to True to indicate the alert system is active

💡 Why This Matters

🌍 Real World

V2V safety systems help cars communicate to avoid collisions by sharing speed and position data in real time.

💼 Career

Understanding basic data structures and loops is essential for developing or testing automotive safety software and embedded systems.

1

Create the vehicles data dictionary

Create a dictionary called vehicles with these exact entries: 'V1': 60, 'V2': 45, 'V3': 80, 'V4': 50. These represent vehicle IDs and their speeds in km/h.

EV Technology

# Create the vehicles dictionary with IDs and speeds
# Your code here

Need a hint?

Use curly braces to create a dictionary with keys as vehicle IDs and values as speeds.

2

Set the safety distance threshold

Add a variable called safety_distance and set it to 30 to represent the minimum safe distance in meters between vehicles.

EV Technology

vehicles = {'V1': 60, 'V2': 45, 'V3': 80, 'V4': 50}
# Set the safety distance threshold
# Your code here

Need a hint?

Use a simple variable assignment to set the safety distance.

3

Identify vehicles exceeding speed threshold

Use a for loop with variables vehicle_id and speed to iterate over vehicles.items(). Inside the loop, check if speed is greater than 50 km/h to identify vehicles that might need safety alerts.

EV Technology

vehicles = {'V1': 60, 'V2': 45, 'V3': 80, 'V4': 50}
safety_distance = 30
# Loop through vehicles to find those exceeding 50 km/h
# Your code here

Need a hint?

Use vehicles.items() to get both keys and values in the loop.

4

Enable the alert system

Add a variable called alert_enabled and set it to True to indicate the V2V safety alert system is active.

EV Technology

vehicles = {'V1': 60, 'V2': 45, 'V3': 80, 'V4': 50}
safety_distance = 30
for vehicle_id, speed in vehicles.items():
    if speed > 50:
        pass  # Placeholder for alert logic
# Enable the alert system
# Your code here

Need a hint?

Set a boolean variable to True to activate alerts.
