Systems and methods for predictive and automatic engine stop-start control

A method of controlling a coast state of a vehicle, the method comprising:

• monitoring, by a vehicle electronic control unit (VECU), environment signals from one or more environmental sensors of the vehicle;
• determining, by the VECU, whether the environment signals indicate a predicted coast opportunity;
• and
• in response to determining that the environment signals indicate a predicted coast opportunity:
• transmitting, by the VECU, a signal to cause a powertrain of the vehicle to be opened;
• determining, by the VECU, whether vehicle state signals from one or more vehicle state sensors of the vehicle indicate a set of conditions for stopping an engine of the vehicle are met;
• and
• in response to determining that the set of conditions for stopping the engine are met, transmitting, by the VECU, a signal to cause the engine to stop.
