Introduction
Self-driving cars represent one of the most complex and transformative applications of AI and deep learning. These vehicles rely on computer vision, sensor fusion, reinforcement learning, and decision-making algorithms to navigate safely.
At CuriosityTech.in, learners in Nagpur explore end-to-end autonomous vehicle pipelines, gaining hands-on experience in deep learning architectures, simulation environments, and real-world deployment considerations, preparing them for cutting-edge AI engineering careers.
- Overview of Self-Driving Car Systems
Self-driving cars rely on multiple AI and sensor modules:
Module Function
Perception Detects objects, lanes, traffic signs using cameras, LIDAR, radar
Localization Determines vehicle position using GPS, IMU, and map data
Prediction Anticipates actions of other road users
Planning Determines optimal path and maneuvers
Control Executes steering, acceleration, braking commands
CuriosityTech Insight: Students learn that perception and planning rely heavily on deep learning, while control systems combine classical and AI techniques.

● Popular models: YOLOv5, Faster R-CNN, SSD
Example: Detecting pedestrians in real-time using a CNN with input from the front-facing camera.
b) Recurrent Neural Networks (RNNs) / LSTMs
● Used for temporal prediction, e.g., predicting pedestrian movement or vehicle trajectories
● Helps vehicles anticipate actions in dynamic environments
c) Reinforcement Learning
● Optimizes decision-making policies for path planning and adaptive control
● Models learn optimal navigation strategies through simulated trials
d) Sensor Fusion Networks
● Combine camera, LIDAR, and radar data for robust perception
