Method for Determining a Predictive Ego Speed of a Vehicle Traveling along a Predetermined Route, Control Device for a Vehicle or for a Navigation Device or for a Mobile User Terminal, Navigation Device and Vehicle

A method for determining a predictive ego speed of a vehicle traveling along a predetermined route, the predictive ego speed being for a location or a section of the predetermined route, the method comprising:

• determining a current average speed of road users currently traveling at the location or the section;
• determining a first average speed, the first average speed being an average of speeds of vehicles that have traveled at the location or the section during high traffic density that is indicative of traffic congestion;
• determining a second average speed, the second average speed being an average of speeds of vehicles that have traveled at the location or the section with a traffic density that is indicative of traffic flowing;
• determining if the current average speed is between the first average speed and the second average speed;
• and
• if the current average speed is determined to be between the first average speed and the second average speed, determining the predictive ego speed based on the current average speed and by interpolating between the first average speed and the second average speed.

A control device comprising:

• a communication link, wherein the communication link is configured to detect an average speed for a location or a section of a predetermined route along which a vehicle is traveling;
• and
• at least one communication interface, wherein the control device is configured to:
• determine a predictive ego speed of a vehicle traveling along a predetermined route, the predictive ego speed being for a location or a section of the predetermined route;
• determine a current average speed of road users currently traveling at the location or the section;
• determine a first average speed, the first average speed being an average of speeds of vehicles that have traveled at the location or the section during high traffic density that is indicative of traffic congestion;
• determine a second average speed, the second average speed being an average of speeds of vehicles that have traveled at the location or the section with a traffic density that is indicative of traffic flowing;
• determine if the current average speed is between the first average speed and the second average speed;
• and
• if the current average speed is determined to be between the first average speed and the second average speed, determine the predictive ego speed based on the current average speed and by interpolating between the first average speed and the second average speed.

A navigation unit for a vehicle or mobile user terminal comprising:

• a navigation device, wherein the navigation device is configured to:
• determine a predictive ego speed of a vehicle traveling along a predetermined route, the predictive ego speed being for a location or a section of the predetermined route;
• determine a current average speed of road users currently traveling at the location or the section;
• determine a first average speed, the first average speed being an average of speeds of vehicles that have traveled at the location or the section during high traffic density that is indicative of traffic congestion;
• determine a second average speed, the second average speed being an average of speeds of vehicles that have traveled at the location or the section with a traffic density that is indicative of traffic flowing;
• determine if the current average speed is between the first average speed and the second average speed;
• and
• if the current average speed is determined to be between the first average speed and the second average speed, determine the predictive ego speed based on the current average speed and by interpolating between the first average speed and the second average speed.

• determine a first average speed, the first average speed being an average of speeds of vehicles that have traveled at the location or the section during high traffic density that is indicative of traffic congestion;
• determine a second average speed, the second average speed being an average of speeds of vehicles that have traveled at the location or the section with a traffic density that is indicative of traffic flowing;
• determine if the current average speed is between the first average speed and the second average speed;
• and
• if the current average speed is determined to be between the first average speed and the second average speed, determine the predictive ego speed based on the current average speed and by interpolating between the first average speed and the second average speed.
