Abstract
A method for determining relative spatial information between a first vehicle and a second vehicle, the method including monitoring a communication channel at the first vehicle and receiving a current communication signal sent by the second vehicle on the communication channel. The current communication signal is received at a received power level. A relative position between the first vehicle and the second vehicle is calculated. Input to the calculating includes an actual or estimated transmitted power level, and the received power level.
Claims38
A method for determining relative spatial information between a first vehicle and a second vehicle, the method comprising:
- monitoring a communication channel at the first vehicle;
- receiving a current communication signal on the communication channel from the second vehicle, the current communication signal received at a received power level;
- and
- calculating a distance between the first vehicle and the second vehicle, wherein input to the calculating includes an actual or estimated transmitted power level and the received power level.
A system for determining relative spatial information between a first vehicle and a second vehicle, comprising:
- a receiver on a first vehicle for monitoring a communication channel;
- and
- a processor for executing instructions to implement a method, the method including:
- monitoring the communication channel at the first vehicle;
- receiving a current communication signal from the second vehicle on the communication channel, the current communication signal received at a received power level;
- and
- calculating a relative position between the first vehicle and the second vehicle, wherein input to the calculating includes an actual or estimated transmitted power level and the received power level.
