(2017·浙江模拟)Nowadays there are many new cars on the road. Some new models are flashy and others are fuel efficient， and embedded technology(嵌入式系统技术） is at the heart of all of them.
The new Ford Escape has a radar－enabled adaptive cruise control（巡航车速控制装置)
to avoid collisions, with sensors on the front and side of the car. Ford’s Mark Schirmer says the electronic system can be accessed through the dashboard or a smartphone.
“I am from Michigan. If it is a cold morning, I can have it start up right before I am scheduled to leave to go to the airport or go to work。 You can find your car or if one of your family members borrows the car， it will show you exactly where it is, ” said Schirmer.
Third－party products now in development， like this emergency warning system, help drivers who fail to hear an approaching siren。 A near miss with an ambulance inspired the product from the Chicago start－up HAAS，co－founded by CoryHohs. “It scared me enough that I started looking for a product that would alert me when they are coming, ” said Hohs。

rom the skin. “If I am drinking and I have levels above a preset limit, it immobilizes the vehicle， so you cannot move the vehicle that you are driving, ” said Carroll.
One company founder says the connected technology is playing an important role in people's daily life.
