Vehicle systems and methods for identification and deduplication of roadway objects

A vehicle system comprising:

• a vehicle control module of a vehicle;
• and
• a control module in communication with the vehicle control module, the control module configured to:
• receive data from a plurality of vehicles over a period of time, the data including detected locations and speed limit values of at least one speed limit sign along a vehicle roadway;
• cluster the received data into a plurality of groups;
• detect at least one set of duplicate groups of the plurality of groups;
• merge the duplicate groups into a single group or remove at least one of the duplicate groups to form a set of deduplicated groups associated with the at least one speed limit sign;
• determine an expected speed limit value of the at least one speed limit sign based on the set of deduplicated groups;
• and
• determine an expected location of the at least one speed limit sign based on the set of deduplicated groups,
• wherein the vehicle control module is configured to:
• receive the expected speed limit value and the expected location of the at least one speed limit sign;
• and
• generate a control signal for controlling at least one operation of the vehicle based on the expected speed limit value and the expected location of the at least one speed limit sign.

A vehicle control method comprising:

• receiving data from a plurality of vehicles over a period of time, the data including detected locations of at least one object along a vehicle roadway;
• clustering the received data into a plurality of groups;
• detecting at least one set of duplicate groups of the plurality of groups;
• merging the duplicate groups into a single group or removing at least one of the duplicate groups to form a set of deduplicated groups associated with the at least one object;
• determining an expected location of the at least one object based on the set of deduplicated groups;
• and
• generating a control signal for controlling at least one operation of a vehicle based on the expected location of the at least one object.
