Problems solved by technology

However, LiDAR sensors and DGPS are more expensive
In addition, these methods require line-of-sight for object detection, thus limiting available ADAS functionality
Although emerging V2V / V2I networks can provide information about distant vehicles or regions, such information still requires precise localization of motor vehicles

Embodiment Construction

[0032] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses.

[0033] refer to figure 1, an advanced driver assistance system (ADAS) according to the principles of the present disclosure is indicated by reference numeral 10 . ADAS 10 is used in exemplary motor vehicle 12 . Motor vehicle 12 is illustrated as a passenger vehicle, however, motor vehicle 12 may be a truck, sport utility vehicle, van, RV, or any other type of vehicle without departing from the scope of the present disclosure. The ADAS 10 can have a variety of configurations without departing from the scope of the present disclosure, but generally includes an ADAS controller 14 in communication with one or more vehicle sensors 16, a global positioning system (GPS) 18, a vehicle-to-vehicle ( V2V) and vehicle-to-infrastructure (VSI) receiver / transmitter 20 , and one or more vehicle control modules 22 . ADAS 10 is configured to perform various ADAS...

Abstract

A method for performing advanced driver assistance system (ADAS) functions for a vehicle includes receiving a plurality of inputs from a plurality of sensors disposed on the vehicle, determining a pool of location candidates of the vehicle based on a first subset of the plurality of inputs, iteratively updating the pool of location candidates based on a second subset of the plurality of inputs, generating an estimate of vehicle location based on an average of location candidates, evaluating a confidence level of the estimate of vehicle location, generating a beyond line-of-sight situation awareness based on the plurality of inputs and locating the vehicle on a digital map based on the confidence level and the estimate of vehicle location, and performing ADAS functions based on the beyond line-of-sight situation awareness and location of the vehicle on the digital map.

Description

technical field [0001] The present invention generally relates to a method and system for performing advanced driver assistance system functions of a motor vehicle using precise vehicle localization and beyond-horizon situational awareness. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0003] Motor vehicles have been designed using increasingly advanced technologies aimed at improving the safety, efficiency and mobility of motor vehicles. One example of such technology includes advanced driver assistance systems. Generally, ADAS automates, adapts, or enhances vehicle systems to improve vehicle safety and / or operator driving performance. ADAS can rely on inputs from multiple data sources, including LiDAR, sonar, ultrasound, radar, and image processing from cameras, and inputs may come from other sources separate from the motor vehicle itself, e.g...
