  • Patent number: 11961403
    Abstract: A system for generating virtual lane markers of an intersection so that the virtual lane markers are visible to an operator of a vehicle at the intersection. The system includes a remote station having a transceiver, a remote memory module configured to store map data and baseline static paths of vehicles moving through the intersection, and a remote control module configured to broadcast via the transceiver a map message indicating the baseline static paths. A vehicle transceiver is configured to receive the map message. A vehicle control module is configured to generate virtual lane markers through the intersection based on the baseline static paths included with the received map message.

  • Publication number: 20240029558
    Abstract: A remote station including a transceiver, a memory, and a control module. The memory is configured to store baseline static paths and dynamic paths of vehicles through an intersection. The baseline static paths refer to at least one of previous predetermined paths, averaged paths or historical paths. The dynamic paths refer to current detected paths. The control module is configured to: (i) compare the dynamic paths to the baseline static paths; (ii) determine whether there is a statistical significance between the dynamic paths and the baseline static paths; and (iii) when there is a statistical significance between the dynamic paths and the baseline static paths, broadcast via the transceiver an alert message indicating that the intersection may include an obstruction.

  • Publication number: 20230316921
    Abstract: A pedestrian collision warning system includes a transceiver, a memory and a control module. The transceiver receives a PSM and a map message at a vehicle. The memory stores map data. The control module: based on the messages, determines possible conflict boxes in which the vehicle and a pedestrian are predicted to be in at a same time; based on the map data and the map message, determines a most likely path of the vehicle through the intersection from possible intersection paths; based on the most likely path of the vehicle and the possible conflict boxes, determines whether the vehicle and the pedestrian will be in a possible conflict box at a same time; and in response to determining that the vehicle and the pedestrian will be in a possible conflict box at a same time, alerts an occupant of the vehicle or the pedestrian of a potential collision.

  • Patent number: 10060380
    Abstract: An inter-connect circuit (ICC) device for a fuel delivery system of a vehicle is disposed between an engine control unit (ECU) and a fuel control device. The ECU transmits a drive pulse to the fuel control device by way of a drive pulse line passing through the ICC device. The ICC device includes a housing and a sense circuit. The housing has a first side that is connectable to the ECU and a second side different from the first side that is connectable to the fuel control device. The sense circuit is disposed within the housing. The sense circuit is electrically coupled to the drive pulse line by way of a sense circuit line and is communicably coupled to the ECU by way of a data communication line.

  • Patent number: 9945373
    Abstract: A pump may have a first chamber and a solenoid coil to control movement of a first valve member. A second chamber may have a second valve member to control fluid moving into a third chamber. A first fluid passageway may link the first and second chambers, a second passageway may link second and third chambers and a third passageway may link third and fourth chambers. After pressurizing the third chamber causing fluid to flow into and leave a fourth chamber, the third chamber depressurizes due to downward movement of a plunger. Upon depressurization with a solenoid coil energized, second valve member floats and then moves against a valve seat. While the second valve member is moving toward the valve seat, the solenoid coil is de-energized causing the first valve member to move and strike the second valve member when the second valve member is moving at maximum velocity.
