Method for determining altitude or road grade information in a motor vehicle
摘要:
A method for determining altitude or road grade information in a motor vehicle includes evaluating altitude or road grade information stored in a digital map by analyzing a GPS signal and/or vehicle data-based estimated altitude or road grade information. When indicated based on the evaluation, the altitude or road grade information is corrected and used as the current altitude or road grade information.
