Thanks to "Intelligent Drive", vehicles from Mercedes-Benz are already able to detect many hazardous situations in road traffic and react as the situation demands. COLLISION PREVENTION ASSIST is on board as standard from the A to the S-Class, for example. This radar-based assistance system warns the driver when a risk of collision arises. And the more advanced COLLISION PREVENTION ASSIST PLUS system, becoming available over all models from Mercedes-Benz, is even able to carry out autonomous braking: if the driver fails to act when a risk of collision is detected, despite the warning lamp in the instrument cluster and the intermittent acoustic alert, the system will automatically trigger braking.
Beyond this, from the C-Class through to the S-Class there are already Mercedes-Benz models driving semi-autonomously on public roads today, equipped with features such as DISTRONIC PLUS with Steering Assist and the Stop&Go Pilot for semi-autonomous traffic jam following.
Autonomous cruise control (ACC; also called adaptive cruise control or radar cruise control) is an optional cruise control system for road vehicles that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead. It makes no use of satellite or roadside infrastructures nor of any cooperative support from other vehicles. Hence control is imposed based on sensor information from on-board sensors only. The extension to cooperative cruise control requires either fixed infrastructure as with satellites, roadside beacons or mobile infrastructures as reflectors or transmitters on the back of other vehicles ahead.
Such systems go under many different trade names according to the manufacturer. These systems use either a radar or laser sensor setup allowing the vehicle to slow when approaching another vehicle ahead and accelerate again to the preset speed when traffic allows - example video. ACC technology is widely regarded as a key component of any future generations of intelligent cars. The impact is equally on driver safety as on economising capacity of roads by adjusting the distance between vehicles according to the conditions. GPS-aided ACC: the GPS navigation system provides guidance input to the ACC. On the motorway, the car in the front is slowing down, but with turn signal on and it is actually heading for a highway off-ramp. A conventional ACC would sense the car in front was decelerating and it would simply apply brakes accordingly. But with GPS-guided ACC takes into account the approaching highway exit and it simultaneously receives images from a camera attached e.g. behind the front pane to the rearview mirror. The camera may detect the turn signal from the car ahead. So instead of braking, this new system continues uninterrupted, because it knows that the car in front will exit the lane.
The next generation, also known as the Cooperative Adaptive Cruise Control, will include information served from a vehicle ahead in the same lane. Such dependent approach however requires standardization across manufacturers and model generations. There is no vision when such agreement could come into practice. All designs without such cooperative support will operate with comparably lower dynamic, but promise better reliability and independent operation.
Google's self-driving vehicles use a combination of GPS, cameras, LIDAR, radar, and the company's mapping technology to navigate accurately. ADAS systems are being mastered to create autonomous driverless, self-driven cars.
Some interesting forms of ADAS are special rearview cameras required by NHTSA starting in 2018; face imaging knows when the driver is nodding off; warnings of local disasters; smartview mirror; lane departure warning systems and more.
Connected Car (definition )- the presence of devices in an automobile that connect the devices to other devices within the car/vehicles and or devices, networks and services outside the car.
Advanced Driver Assistance Systems, or ADAS, are systems to help the driver in the driving process. When designed with a safe Human-Machine Interface, they should increase car safety and more generally road safety.
