Top 10 ADAS technological solutions that enhance growth in the automobile industry

Vehicle safety is one of the substantial sections that has heavily captivated capitalization of the automotive manufacturing companies. In the last few years, car providers have innovated technologies that have the capability to prevent fatal road incidences, referred to as advanced driver assistance systems (ADAS). This technology automatically facilitates and advance the vehicular system that assists the driver or even autonomously substitute for a safer and improved driving experience. ADAS has exposure not only in private car but also a wide range of vehicle fleet, including delivery fleets, commercial fleets, trucking fleets, taxi cab fleets, etc.
Let us find out the top ADAS technologies that improve vehicle safety and offer comfortable driving.
One of the most primarily utilized ADAS technology, parking assistance system utilizes ultrasonic sensors to trigger the driver in detecting obstacles while assisting in parking. The system is fixed on the front and rear bumpers of the vehicle, integrated with a rear cam to provide visual assistance; it also has the ability to detect the alarming distance amid the vehicle and obstacle. Parking assistance system was first marketed by Toyota Motor Corp. in 1999 in its Lexus models and hybrid Prius models. The majority patent for parking management systems is owned by Bosch and Ford Global Technologies.
Tire pressure monitoring system (TPMS) warns the driver about the significantly under-inflated tire, possibly creating unsafe driving conditions. The system overcomes several challenges by giving a pressure drop warning system on vehicles. Some of the noted advantages of proper tire inflation pressure are improved fuel economy, reduces braking distance, better handling, and increase in tire life. TPMS are classified into two categories, namely, direct and indirect.
AFS system is the electronic successor of the previous mechanical directional headlight system that assists in improved driving, especially during nighttime, by automatically adjusting the headlight in response to vehicle steering, suspension dynamics, vehicle speed, weather, visibility condition and road contour. It has been in the market since 2003 with several manufacturers like BMW, Toyota and Opel using this feature in their vehicles. This technology is optional even in high-end cars, which indicate the huge scope for the future market. Players who own patents for this technology are Adaptive Lighting, General Electric, Koito Manufacturing Co., Ltd., ZKW Group. Ford and Hyundai.
Lane departure warning systems abbreviated as LDWS is equipped with video cameras or laser or radio sensors to detect the vehicle position in the lane and alarm the driver either through a visual alert or through an audiovisual alert in the drifting situation. The advanced versions of LDWS have an add-on advantage of taking action to keep the vehicle in the lane with the help of a counter-steering effect, which is generally termed as ‘Lane Keep Assist.’
The studies conducted by IIHS, Mercedes, Volvo and Acura have proved that the installation of collision warning/forward collision warning systems reduces property damage liability insurance claims by 14%. The CWS or FCWS (Frontal Collision Warning System) uses radar mounted on the bumper of the car, which continuously analyzes the vehicles and objections on the road. The warning system alerts the driver by blinking a caution light or by an audible warning of a potential collision. The technology uses a camera-based system or radar-based system. The radar-based systems provide more accurate data regarding the vehicle’s distance and speed and operate well in almost all weathers.
BSD uses electronic detection device, mounted near the external rearview mirrors or the rear bumpers. Electromagnetic waves are sent by these devices to capture digital images for analysis. The first company to introduce BSD was Ford in 2005 under the name of Blind Spot Information System (BLIS). Today, BSD is advanced with an added assist feature that steers the car back into the safety zone. Some leading players in the BSD space include Autoliv, Continental, Valeo, Delphi Automotive PLC, ADASENS Automotive GmbH, Hyundai Mobis Co. Ltd., Robert Bosch GmbH, Xiamen Autostar Electronics and ZF TRW.
ESC uses traction control and anti-lock braking systems to control the vehicle, even when the driver loses control. In a study by Monash University in Australia, it was observed that ESC systems help in reducing crashes in vehicles. The market is boosted by consumer awareness for the safety features of ESC. The NHTSA has made ESC mandatory for trucks and buses with a gross weight of more than 26,000 pounds and also for passenger cars, multipurpose passenger vehicles, trucks and buses with a gross weight less than 10,000 pounds. The major players in the ESC market include Robert Bosch, Delphi, Denso, Continental, TRW Automotive and Advics.
Adaptive Cruise Control (ACC) is an ADAS system that helps in maintaining speed and keep a safe distance between the vehicles ahead. The system maintains the speed and also intervenes to reduce speed in case of any potential threats. The ACC systems are either laser-based or radar-based. Their popularity has sky-rocketed in the last two-three years and is now common in sedans and hatchbacks.
AEBS is another name for Collision Avoidance System, which monitors and takes control of a vehicle in an emergency. Most AEB systems use radar, (stereo) camera and/or LiDAR-based technology to identify potential collisions ahead of the car. AEB systems are mostly present in the top end and luxury models and now is gaining popularity amongst other sub-segment vehicles as well.
These traffic sign recognition systems are integrated from detection techniques in an image format through an on-board road-facing camera. Traffic sign images are stored in the repository, which is later processed by the augmented computerized system in the vehicle to acknowledge the sign, based on the colour or shape using an advanced algorithm. This helps keep track of the speed limit in the region and helps avoid speeding.
Other than the above-mentioned advanced driver assistance systems (ADAS), there are many other functions which assist in automated driving, enabling safety of vehicles, drivers and the public on the road. For developers, the future of ADAS lies in five key trends; sensors, connectivity, automotive human-machine interface (HMI) design embedded vision and automotive systems infrastructure.
