'Driverless' can be divided into four levels depending on the degree of 'automation': Level 1, function-specific autopilot, adaptive cruise control only, autobrake and lane keeping functions; level 2, Merge-function autopilot , To achieve partial automatic parking into place, to provide assistance in traffic jams, emergency braking with steering, etc .; third level, limited automatic driving, to achieve automatic and line, adaptive cruise control based on lane centerline positioning, autonomous parking into place The fourth level, fully automatic driving, real autopilot, parking pilot. The first three 'driverless' implementations require an Advanced Driver Assistance System (ADAS).
ADAS (Advanced Driver Assistance System) is not a configuration, but several configuration coordination system, simply put, is the use of various complementary sensors installed on the car, such as radar, ultrasonic, V2X technology, in the car Real-time perception of the surrounding environment during driving and data collection, through the operation and analysis of the system, to allow drivers to detect the possible danger in advance, thus effectively increasing the comfort and safety of driving a car.
A car in order to get rid of the driver to achieve 'driverless' need to be equipped with multiple complementary sensors such as radar, camera, laser locator, ultrasonic and V2X, etc. They seem to be the car's 'eyes' through the vehicle around things And environment sensing, collecting relevant data and submitting it to the driving system for adaptive cruise control, blind spot monitoring, lane departure warning, night vision, lane keeping assist and collision warning systems under a variety of conditions, with Automatic steering and brake intervention.
V2X technology, driverless 'Clairvoyant'
V2X technology, ie, car-to-car and car-to-infrastructure technology, enables vehicles to be effectively received by detecting traffic jams or traffic risks prior to detection by the naked eye and detection of driving assistance systems and by issuing early warning messages within a few hundred meters Traffic jams or roadwork sites; in addition, vehicles equipped with V2X connected devices can also receive information from smart road signals and automatically identify the traffic light's operating cycle, so that the large Enhance road safety and improve traffic efficiency.
Safe V2X technology is essential for the future of unmanned and intelligent transportation systems.According to a research report by the U.S. Department of Transportation, safe and reliable V2X technology will reduce over 80% of traffic accidents.
As a global technology leader in Secure Connected Vehicles, NXP is actively involved in the earliest V2X technology trials and is leading the V2X ecosystem with RoadLINK, the first connected car solution launched in 2013. Not long ago, NXP officially became a member of the National Intelligence Network The new member of the joint pilot demonstration area of Shanghai Automotive (Shanghai) Co., Ltd. will vigorously promote the testing and development of the relevant technical specifications of China's first vehicle network based on DSRC technology.
Radar sensor, unmanned 'downwind ear'
According to IHS Research, from 2016 to 2019, the market average annual growth rate of automotive radar sensors will be the same as the average annual growth rate of automotive radar sensors, with the increase in different levels of autonomous driving, with more radar sensors installed on each vehicle Reaching 27%, and the total market demand is expected to reach 50 million by 2021. NXP unveiled the industry's first postmarked size (7.5mm * 7.5mm) single-chip 77GHz high-resolution RF CMOS IC radar chip that accurately delivers the automotive Driving environment NXP car radar chip size so small that it can be installed almost invisible anywhere in the car, and its power consumption 40% lower than the traditional radar chip products for the automotive sensor design and installation Provides great convenience.
Bluebox Platform, Driverless 'Ultimate Brain'
Complicated crowded pavements and rapidly changing conditions make it impossible for IWC cars to have only a pair of 'clairvoyant' eyes and a pair of 'downwind' ears.Although a series of complementary sensors can draw high-precision maps of the car's surroundings and accurately detect objects, To make precise and safe driving operations, the car needs to be equipped with a 'ultimate brain' that quickly processes and integrates multiple streams of information and ultimately completes the car's driving operations.
As the largest automotive semiconductor company in the world, the BlueBox platform designed and developed by NXP provides automotive manufacturers with off-the-shelf integrated autonomous driving calculation solutions. BlueBox is a central computing engine designed for autonomous driving. Artificial Intelligence also provides interfacing support for shop newsletters and multiple sensors, acting as the 'nervous system' of vehicles.
In a driverless vehicle system, multiple sensor data streams are fed into the BlueBox engine, and the data stream is combined to create a 360 ° real-time model of the physical environment surrounding the vehicle.The platform features a LIDAR system with NXP chip support, radar and vision Node from which the NXP S32V processor takes sensing data inputs and creates a map with sensing fusion capabilities The S32V includes a graphics engine specifically designed with high-quality graphics accelerators and a car-level functional safety engine.
According to Prospect Industry Research Report 2016-2021 Analysis of China's Driverless Vehicle Industry Forecasting and Investment Strategy Planning, ADAS is now mature and its global market penetration rate will exceed 25% in 2019. The agency predicts that by 2020 ADAS market in China in the 700 billion -800 billion yuan, an average annual compound growth of about 60% .As the world's largest supplier of automotive semiconductors, NXP to the autonomous driving industry's great development as an opportunity to provide both induction, thinking and decision-making Driving technology and product portfolio, with more than 60 years of automotive experience, and actively promote the occurrence of industrial change.
