Introduction

High Cost of Mobility

Running Out of Space

A Self-Driving Car?

Driving Demographics

Safety and the Human Toll

Six million vehicle crashes leading to 32,788

traffic deaths in 2010 in US

Traffic crashes cost Americans $299.5 billion

annually

Goal not merely to make self-driving vehicles

as safeas human drivers

But goal is to develop crash-lesscars

Convergence


6/24

Sensor-Based Solutions

Use a combination of advanced sensors,

stereo cameras

long- and short-range RADAR,

actuators, control units, and integrating software, to enable cars to monitor and

respond to their surroundings.

Some ADAS solutions,

lane-keeping and warning systems,adaptive cruise control,

back-up alerts, and parking assistance


7/24

Connectivity-Based Solutions

Use of wireless technologies to communicate in real timefrom vehicle V2X and vice versa.

According to the USDOT, as many as 80 percent of all couldbe mitigated using connected-vehicle technology.

Dedicated Short-Range Communication (DSRC) Uses radio waves V2V communication. It operates at 5.9 GHz

frequency, using standards such as SAE J2735 and the IEEE 1609suite

Provides:

Network acquisition Low latency, High reliability

Priority for safety applications

Security and privacy


8/24

Convergence

Convergence of communication- and sensor-

based technologies could deliver better safety,

mobility, and self driving capability than either

approach could deliver on its own.

What is it?

How to design/program one?

Programming a self-driving car

Localization(Monte Carlo Localization)

Tracking(Kalman filter)

Particle Filter(State of the System) Motion Planning

Control(PID)

Combining them ALL.

Vehicular Communication

Cooperative Approach to communicate between V2X andvice-versa.

Full 360around vehicle situation awareness ,far morereliable than local sensors

Provides a bigger coverage area in all directions, warningsabout different hidden hazards such as accidents orobstacles behind a curve Cooperative Adaptive Cruise Control

Cooperative Merging

Cooperative Platooning Cooperative Collision Avoidance

One big drawback of the sensors is that they are influencedby weather conditions and by mud or dirt
