Abstract
Official abstract text for this publication.
A method for determining a velocity of headwind flowing in the direction of a vehicle, based on a coolant mass flow of a coolant flowing through a heat exchanger of a cooling device of the vehicle, and an air mass flow flowing through the heat exchanger and triggered by the headwind, includes: determining a temperature drop of the coolant mass flow; determining the air mass flow responsible for the temperature drop of the coolant mass flow; and determining the velocity of the headwind flowing in the direction of the vehicle, based on the air mass flow responsible for the temperature drop of the coolant mass flow.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for determining a velocity of a headwind flowing in the direction of a vehicle, based on (i) a coolant mass flow of a coolant flowing through a heat exchanger of a cooling device of the vehicle, and (ii) an air mass flow flowing through the heat exchanger and triggered by the headwind, the method comprising: determining a temperature drop of the coolant mass flow; determining the air mass flow responsible for the temperature drop of the coolant ma…
