System of automatic driving assistance, roadside assistance and vehicle-side assistance

A roadside assistance system, comprising a plurality of roadside sensors, a roadside device, and a roadside Vehicle to Everything (V2X) communication device, wherein:

• each of the plurality of roadside sensors is configured to collect environment information of an ambient environment and transmit the environment information to the roadside device;
• the roadside device is configured to:
• generate a plurality of messages from the environment information collected by the plurality of roadside sensors, the plurality of messages including a plurality of pieces of sensed information, each piece of sensed information being generated from the environment information collected by a respective one of the plurality of roadside sensors,
• combine the plurality of messages generated from the environment information collected by the plurality of roadside sensors into a single message at least by removing redundant sensed information based on a confidence level associated with each piece of sensed information, the single message comprising combined sensed information, and
• transmit the combined sensed information to the roadside V2X communication device;
• and
• the roadside V2X communication device is configured to transmit the combined sensed information to a vehicle-mounted V2X communication device.

A vehicle-mounted assistance system, comprising a vehicle-mounted Vehicle to Everything (V2X) communication device connected to a vehicle-mounted automatic driving system, wherein:

• the vehicle-mounted V2X communication device is configured to receive combined sensed information from a roadside V2X communication device and transmit the combined sensed information to the vehicle-mounted automatic driving system,
• the roadside V2X communication device is coupled to a plurality of roadside sensors, wherein each of the plurality of roadside sensors is configured to collect environment information of an ambient environment and transmit the environment information to a roadside device, and
• the roadside V2X communication device is coupled to the roadside device that is configured to:
• generate a plurality of messages from the environment information collected by the plurality of roadside sensors, the plurality of messages including a plurality of pieces of sensed information, each piece of sensed information being generated from the environment information collected by a respective one of the plurality of roadside sensors, and
• combine the plurality of messages generated from the environment information collected by the plurality of roadside sensors into a single message at least by removing redundant sensed information based on a confidence level associated with each piece of sensed information, the single message comprising combined sensed information.
