ADAS

Advanced driver-assistance systems (ADAS) are electronic systems in a vehicle that use advanced technologies to assist the driver. They can include many active safety features, and often the terms “ADAS” and “active safety” are used interchangeably.

ADAS uses sensors in the vehicle such as radar and cameras to perceive the world around it, and then either provides information to the driver or takes automatic action based on what it perceives.

ADAS features that provide information will most commonly include “warning” in the name. For example, if the vehicle detects an object such as another vehicle or a cyclist in a location where the driver may not be able to see them, features such as blind spot warning or rear backup warning will alert the driver. Likewise, if the system determines that the vehicle is drifting out of its lane, it could activate lane departure warning to alert the driver.

When these detections are coupled with a technology that takes action beyond a simple warning, ADAS becomes an active safety system – meaning the vehicle will “actively” control braking or steering. These features most commonly include “assistance” in the name.

ADAS also includes propulsion functions such as adaptive cruise control, which varies speed to ensure that a vehicle maintains a safe distance from the vehicle in front of it. More sophisticated ADAS features can even manage steering and propulsion without the need for hands-on control from the driver under certain conditions, such as highway driving or stop-and-go traffic. These are typically referred to as Level 2+ active safety systems and represent some of the most advanced functionality currently available on the market.

As vehicles take on more ADAS features and build toward automated driving, the resulting increase in software is creating an immediate need for significantly more powerful compute. To accomplish this in a flexible and scalable way ALTEN Global Technologies has been investing in merging their 3 decades experience in GPS communication with the Infotainment platform to incorporate the basic ADAS features targeting the low and mid segments of ASIA in the first phase of competency building activities.

ADAS progress at ALTEN Global Technologies

ALTEN Global Technologies has invested in ADAS technologies with the basic technologies on ACC, AEB and LDA features, ALTEN Global Technologies has been adding the external resources with high skill sets on – ADAS Application Engineer, AI Model and Deep Learning, Embedded Software, Hardware Engineer, Integration experts, Vehicle Test engineers. Making teams on various features as well as working on multiple proof of control concepts for the same.

The adoption of Level 0 to Level 2 is Advanced Driver Assistance Systems (ADAS). With the transition beyond Level3 Autonomous driving features completely avoid driver intervention for all scenarios (Different type of roads, weather conditions etc.)

ALTEN Global Technologies is laying ground work on ADAS level 0 to level2 features. Development timeline is divided in to three phases. Our core engineering team is analyzing and implementing the algorithms, software stack, and identifying ADAS hardware.

ALTEN Global Technologies objective is to understand and conquer latest technology and algorithms like Deep learning and machine learning used in ADAS systems, further improving and implementing to our software stack.

ALTEN Global Technologies road map is to develop 14 features targeting up to Level2 as per Society of Automotive Engineers (SAE).

Phase 1:

1. Adaptive Cruise Control (ACC)
2. Forward Collision Warning (FCW)
3. Autonomous Emergency Braking (AEB)

Phase 2:

1. Lane Departure Warning (LDW)
2. Lane Keep Assist (LKA)
3. Lane Centering (LC)
4. Blind Spot Monitoring (BSM)
5. Rear Cross Traffic Alert (RCTA)

Phase 3:

1. Object Detection (Deep learning Model) - OD
2. Traffic Sign Recognition (TSR)
3. Pedestrian Detection (PD)
4. Driver drowsiness detection (DDD)
5. Driver Monitoring (DM)

Phase 4:

1. Adaptive cruise control (ACC) with LIDAAR, RADAAR, CAMERA

The major challenges faced during development of ADAS system is the availability of sensors such as cameras, Lidar, automotive radars, etc. Next bottleneck is the compatibility with Hardware architecture. ALTEN Global Technologies has gained full insight into identifying building blocks thereby reducing time to spend on these tasks.

ALTEN Global Technologies is developing Phase1 features, initially our goal is to test these features with Toy car. Phase1 features take full advantage of Radar technology. Phase2 and Phase 3 features are more into Camera based technology where AI and Deep Learning technology are used.. In final stage Phase3, sensor fusion based ACC is planned where Lidar sensor also considered.

Advanced Driver Assistance Systems (ADAS) are being integrated into more vehicles, which offer enhanced safety (collision avoidance, route following, obstacle detection, automatic braking), driver assistance (lane keeping, lane following, adaptive cruise control), etc.

Forthcoming times are extremely promising, as ALTEN Global Technologies will endeavor to compete in the areas of ADAS features blending the AD levels of 3+ and 4. Also ALTEN Global Technologies will integrate the ADAS features with Vehicle Integration and Data management solutions including Telematics data interface, Communication protocols, and Cloud data management.
