US 2019/0096249 A1 · INFRASTRUCTURE BASED BACKUP AND EXIT AID

Abstract

Infrastructure-based warning system having the ability to detect cross-traffic long before onboard vehicle sensors, and broadcast a basic safety message (BSM) including the vehicle's global position, velocity, heading, etc. over dedicated short-range communication (DSRC). A vehicle leaving a parking space is able to receive broadcast over DSRC from infrastructure and provide the driver with an HMI warning that it is unsafe to backup. A vehicle exiting from a blind alley way or parking garage may be positioned such that the driver of the vehicle may not see that there is a pedestrian about to cross and that there is cross-traffic. The infrastructure mounted sensor is able to detect the pedestrian and cross-traffic and broadcast their location, velocity, and headings. The vehicle receives the BSM from the infrastructure and provides the driver with an HMI warning that it is unsafe to move out into the crosswalk and road.

Dependent claims

An apparatus, comprising:

an infrastructure-based warning system, including:
at least one sensor operable for detecting one or more objects in a detection area;
an infrastructure component, the at least one sensor connected to the at least one infrastructure component;
at least one vehicle operable for communication with the at least one sensor;
and
a path of travel, the vehicle able to move along the path of travel;
wherein the vehicle receives a signal from the at least one sensor indicating when there is an object approaching the path of travel.

4 more elements

An infrastructure-based warning system, comprising:

a detection device;
at least one sensor operable for detecting one or more objects in a detection area, the at least one sensor being part of the detection device;
a first communication device in electrical communication with the at least one sensor, the first communication device being part of the detection device;
at least one infrastructure component, the detection device being mounted to the at least one infrastructure component;
a second communication device being part of a first vehicle, the second communication device in wireless communication with the first communication device;
and
an indicator device being part of the first vehicle, the indicator device in electrical communication with the second communication device;
wherein the at least one sensor detects at least one of the location, speed, and direction of a second vehicle, and the at least one sensor sends a signal to the first communication device, and the first communication device sends a signal to the second communication device when there is a potential risk of collision with the second vehicle, and the indicator device provides a warning of the potential risk of collision to the driver of the first vehicle.
