Abstract
A vehicle computer comprises a processor and a memory. The memory stores instructions executable by the processor to receive a location of a first stationary directional short-wave antenna, to determine a line from a vehicle location to the location of the first stationary antenna, to transmit a short-wave request message to the first stationary short-wave antenna based on the determined line, the message including vehicle data, and upon receiving a short-wave acknowledgment message from the first stationary short-wave antenna, to transmit a second short-wave message including vehicle data.
Claims18
A vehicle computer, comprising a processor and a memory, the memory storing instructions executable by the processor to:
- receive a location of a first stationary directional short-wave antenna;
- determine a line from a vehicle location to the location of the first stationary antenna;
- transmit a short-wave request message to the first stationary short-wave antenna based on the determined line, the message including vehicle data;
- and
- upon receiving a short-wave acknowledgement message from the first stationary short-wave antenna, transmit a second short-wave message including vehicle data.
A system, comprising a processor and a memory, the memory storing instructions executable by the processor to:
- upon receiving a first short-wave request message from a vehicle within a coverage area of a first stationary short-wave antenna, transmit a second short-wave acknowledge message to the vehicle based on a vehicle location;
- predict a second location of the vehicle based on a vehicle location and a vehicle trajectory;
- transmit a third short-wave message to the vehicle based on the predicted second location of the vehicle;
- upon determining that a line extending from a first stationary short-wave antenna location to a vehicle location is blocked, identify a message path from the first stationary short-wave antenna to the vehicle location via a second vehicle;
- and
- transmit the third message to the second vehicle including an identifier of the vehicle, a number of hops between the vehicle and the first stationary short-wave antenna, and a payload.
A system, comprising:
- a vehicle computer, programmed to:
- receive a location of a first stationary directional short-wave antenna;
- determine a line from a vehicle location to the location of the first stationary antenna;
- transmit a short-wave request message to the first stationary short-wave antenna based on the determined line, the message including vehicle data;
- and
- upon receiving a short-wave acknowledgment message from the first stationary short-wave antenna, transmit a second short-wave message including vehicle data, and a stationary computer, programmed to:
- upon receiving a first short-wave request message from a vehicle within a coverage area of a first stationary short-wave antenna, transmit a second short-wave acknowledge message to the vehicle based on a vehicle location;
- predict a second location of the vehicle based on a vehicle location and a vehicle trajectory;
- transmit a third short-wave message to the vehicle based on the predicted second location of the vehicle;
- upon determining that a line extending from a first stationary short-wave antenna location to a vehicle location is blocked, identify a message path from the first stationary short-wave antenna to the vehicle location via a second vehicle;
- and
- transmit the third message to the second vehicle including an identifier of the vehicle, a number of hops between the vehicle and the first stationary short-wave antenna, and a payload.
