Sensors The Eyes and Ears of Autonomy
LiDAR
Radar
Cameras
Ultrasonic Sensors
LiDAR uses lasers to measure distances to
objects, providing a 3D point cloud of the
environment.
Radar uses radio waves to detect objects,
regardless of weather conditions, providing
information on range, speed, and direction.
Cameras capture visual data, allowing the vehicle
to recognize objects, traffic signals, and other
environmental features.
Ultrasonic sensors emit sound waves to detect
nearby objects, primarily used for parking
assistance and proximity detection.

Actuators Executing the Decisions
Steering
Brakes
1
2
Actuators control the steering wheel, enabling
the vehicle to change lanes or navigate curves.
Actuators apply the brakes, slowing down or
stopping the vehicle as needed.
Throttle
3
Actuators control the throttle, regulating the
engine's power and speed.
4
Embedded Software The Brain of Autonomy
Data Processing
Decision-Making
Embedded software processes sensor data,
filtering out noise and extracting relevant
information.
Software algorithms analyze the processed data,
making decisions about steering, braking, and
acceleration.
Real-Time Control
Software ensures the vehicle responds quickly and
reliably to dynamic changes in the environment.
5
Data Integration and Processing
Sensor Fusion
Real-Time Processing
Combining data from multiple sensors increases
accuracy and reliability by reducing individual
sensor limitations.
Embedded systems must process vast amounts of
data rapidly to make split-second decisions.
6
Decision-Making Algorithms
Lane Keeping
Obstacle Avoidance
Adaptive Cruise Control
Algorithms maintain the vehicle within its lane,
adjusting steering to compensate for lane
deviations.
Algorithms detect obstacles in the path and
initiate appropriate actions, such as braking or
steering around them.
Algorithms maintain a safe distance from the
vehicle ahead, automatically adjusting speed and
braking.

Communication Interfaces Connecting the Systems
LIN
CAN
FlexRay
Ethernet
Local Interconnect Network used for low-speed
data communication between subsystems.
Controller Area Network for high-speed
communication between various electronic control
units.
A deterministic communication protocol used in
safety-critical systems.
High-bandwidth network used for data exchange and
communication with external systems.
