Abstract
A measurement vehicle for use with a vehicle under a coastdown test on a surface includes a chassis including one or more wheels, and a propulsion system coupled to the chassis. The propulsion system is configured to drive the one or more wheels to move the measurement vehicle relative to the vehicle. The measurement vehicle includes at least one sensor configured to observe one or more conditions associated with the coastdown test and a communication system configured to transmit the one or more conditions to the vehicle.

A measurement vehicle for use with a vehicle under a coastdown test on a surface, comprising:
- a chassis including one or more wheels;
- a propulsion system coupled to the chassis, the propulsion system configured to drive the one or more wheels to move the measurement vehicle relative to the vehicle;
- at least one sensor configured to observe one or more conditions associated with the coastdown test;
- and
- a communication system configured to transmit the one or more conditions to the vehicle.
A method for measuring wind during a coastdown test of a vehicle on a surface, comprising:
- providing a measurement vehicle independent of the vehicle, the measurement vehicle including a chassis with one or more wheels driven by a propulsion system;
- observing a wind speed and a wind direction with an anemometer coupled to the measurement vehicle;
- controlling, by a processor associated with the measurement vehicle, a proximity of the anemometer to the vehicle during the coastdown test;
- and
- communicating, by the processor associated with the measurement vehicle, the wind speed and the wind direction to the vehicle.
A measurement vehicle for use with a vehicle under a coastdown test on a surface, comprising:
- a chassis including one or more wheels;
- a propulsion system coupled to the chassis, the propulsion system configured to drive the one or more wheels to move the measurement vehicle relative to the vehicle;
- a power source in communication with the propulsion system;
- an anemometer configured to observe a wind speed and a wind direction associated with the coastdown test;
- a velocity sensor configured to observe a velocity of the measurement vehicle;
- a communication system configured to transmit the wind speed, the wind direction and the velocity to the vehicle;
- a proximity sensor configured to observe a distance between the anemometer and the vehicle;
- a controller, having a processor configured to:
- determine a proximity of the anemometer to the vehicle based on the distance;
- and
- output one or more control signals to control an output of the propulsion system based on the proximity of the anemometer to the vehicle.
