Just what is that thing on top of the Google Car? What does adaptive cruise control with lane assist mean? When are these things going to be ready? The answer to these questions and more in a technology overview that unravels just how these vehicles are going to work. Presented at the 2017 D-STOP Symposium.

• Autonomous – A vehicle that can operate, in some
manner, without constant direction from the driver
• Connected – A vehicle that can communicate with
other vehicles and infrastructure

12. The car will identify the vehicle in front of it and match speeds to maintain
a safe following distance (set by the user) while not exceeding a certain
speed (also set by the user)
Adaptive Cruise Control
Automatically adjust speeds in a traffic jam, including braking to a full stop,
and handles the steering. Driver must stay alert, but does not have to
touch the wheel or pedals.
Traffic Jam Assist
Alerts the driver when the system detects that the vehicle is about to leave
its lane and can automatically correct the steering and keep the car on
course
Lane Keep Assist
The car will detect panicked breaking and apply more pressure to the
brakes to stop the car faster.
Emergency Brake Assist
Automatically parallel parks a car, as long as the gap is 1.2 times the size of
the car.
Parking Assist
Automatically applies the brakes for obstacle avoidance.
Auto Braking
Semi-autonomous features are safety based – and their incorporation in
current models will begin to reduce accidents in the next 5 to 10 years.
Conclusion
Semi Autonomous Features

13. • Through use of just V2V BSM to warn
drivers, with a mature system, NHTSA
studies indicate that up to 79% of
unimpaired crashes could be avoided.
• Using just a V2I communication system,
NHTSA estimates that 26% of unimpaired
crashes could be avoided.
• Together, NHTSA studies indicate that 81%
of all unimpaired crashes could be
avoided with a fully mature V2V and V2I
system.
Benefits
V2X Introduction
• By 2029, seven years after the projected phase-in of the light vehicle V2V rule, 60% of all vehicles, or a cumulative
146 million cars, will have DSRC/V2X equipment.
• Adoption of aftermarket/consumer electronics DSRC devices will outpace factory installed DSRC within five to six
years after a NHTSA Light Vehicle V2V rule requiring 100% of all new vehicles to be equipped with V2V.

14. Timelines
Technology predictions seem to be coalescing around a 2021 commercial
available start-date, but there are still many issues to be resolved
