Predictive powertrain control using powertrain history and GPS data
First Claim
Patent Images
1. A method of controlling a vehicle powertrain, said method comprising using a controller for:
- (1) determining a present location of the vehicle using a GPS;
(2) predicting a route of travel for the vehicle from the present location based on the current day and time;
(3) identifying historical GPS points within the predicted route of travel that are traveled after the present location of the vehicle based on matching days and times, the historical GPS points including battery charging locations;
(4) when all historical GPS points within the predicted route of travel are identified, retrieving historical powertrain loads and speeds from a memory for the predicted route of travel and the identified historical GPS points;
(5) optimizing a powertrain operation of the vehicle for the predicted route of travel and the identified historical GPS points based on the retrieved historical powertrain loads and speeds; and
(6) updating the present location of the vehicle and repeating steps (2) through (6).
