LANE CHANGE DETECTION AND TRACKING FOR A SAFE-LANE APPROACH USING SENSOR

2022-12-23
2022-28-0489
Improved economic status of people leads to an increase in vehicle density across the world. Many road accidents caused due to poor lane discipline followed by drivers that need to be addressed. Lane discipline can be made possible by educating drivers about its importance and also ensured by effective detection and tracking of vehicles that are plying on the highways. This can be achieved by fixing a device in every vehicle that can detect and track the lane adopted by the vehicle driver during each journey. In this work, a simple lane tracking and detective device is fabricated that consists of an ultrasonic sensor, which is the primary detector that helps in identifying the lane in which the vehicle is moving. The position of the vehicle is recorded by calculating the distance between the right side of the vehicle and the divider that is placed in between the highways.

V2X Communications Message Set Dictionary™ Set

2022-11-14
CURRENT
J2735SET_202211
This Abstract Syntax Notation (ASN.1) File is the precise source code used for SAE International Standard J2735. As part of an international treaty, all US ITS standards are expressed in "ASN.1 syntax". ASN.1 Syntax is used to define the messages or "ASN specifications". Using the ASN.1 specification, a compiler tool produces the ASN library which will then be used to produce encodings (The J2735 message set uses UPER encoding). The library is a set of many separate files that collectively implement the encoding and decoding of the standard. The library is then used by any application (along with the additional logic of that application) to manage the messages. The chosen ASN tool is used to produce a new copy of the library when changes are made, and it is then linked to the final application being developed. The ASN library manages many of the details associated with ASN syntax, allowing for subtle manipulation to make the best advantage of the encoding style.

BC102A: Panel Discussion: Does High Performance Separate More from General Transportation with Respect to Brakes on Electrical Vehicles?

2022-10-12
The electrification of passenger cars is leading to new architectures with higher brake and driveline system complexities. Due to more regenerative braking, the reduced usage of friction brakes may eventually lead to downsizing the friction brakes on �standard� passenger cars. High performance EVs may be facing a different situation as they achieve the speed and acceleration of ICE performance cars. Regenerative braking will be applied here also. However, friction brakes may need to be upsized to compensate for increased power and weight. Also to be considered are stability control, vehicle dynamics, and different driving profiles. The panel will provide an overview on whether or not this will lead to a higher degree of differentiation on EV braking systems.

2022-28-0104
Automotive industry is going through a massive digital transformation to enable advance ADAS functions like cruise control, safety and parking assist. To develop and test advance and complex deep neural network-based AI/ML ADAS models, the need of huge amount of rich and diverse annotated data is utmost important. Over the past decade it has been observed that annotation complexity has increased tremendously and evolved from a simple bounding box to complex annotations like segmentation, 3D bounding box, key points etc. that too with multiple sensor integration. Hence such stupendous annotation task cannot be executed inhouse unlike in the past, companies choose to outsource time consuming and labor-intensive task to third party vendors. Hence annotation becomes an additional and unexpected challenge in ADAS function development, which urge the need for standard annotation format.

Automatic Radar Obstacle Classification Using LSTM

2022-10-05
2022-28-0009
Automobile sector is growing every day with fast affinity towards Autonomous vehicles. The most challenging task of ADAS based driverless car is to identify and track the objects in front of the vehicle. To implement this type of technology we require a robust algorithm which can classify the object just-in-time and have great accuracy. We are using automotive radar sensor of 77GHz frequency. Quite often we’ve noticed sudden fluctuations in prediction of the obstacles using either heuristic or even machine learning techniques which focus only on frame-wise / cycle-wise data. So, this inspires us to investigate the history of the data coming in as opposed to only one cycle at a time. Hence, we incorporated a technique wherein we could make use of the past data as well as current cycle data. In this paper, we’ve used Radar time series data to classify the object in front of the Ego vehicle in each Radar cycle.

Challenges with On Board Monitoring

2022-10-04
The upcoming Euro 7 regulation includes a proposal for On Board Monitoring, or OBM, to continuously monitor vehicles for emissions conformance. OBM relies on feedback from sensors and models to identify high emitting vehicles, which poses many challenges. Sensors are not commercially available for all emissions constituents, and the accuracy of commercially available sensors is not capable enough for in use compliance determination. On board emissions models also do not currently have enough fidelity to determine in use compliance and implementation of models is complicated. The stack up of multi-component deterioration leading to an emissions exceedance is possible but also infeasible to detect using available sensors and models. The presentation will review what is being promulgated elsewhere in regard to using on-board sensors to directly measure pollutants such as CARB�s �REAL NOx Tracking� system.
