Systems and methods for vehicle coasting recommendation

An apparatus for providing a coast recommendation for an operator of a vehicle, the apparatus comprising:

• a processor;
• and
• a memory including instructions that, when executed by the processor, cause the processor to:
• receive vehicle position data;
• determine a projected route based at least in part on the vehicle position data;
• determine a first speed change position and a first speed change target speed based at least in part on the projected route;
• determine a first residual speed and a first residual speed position based at least in part on the first speed change position and the first speed change target speed;
• determine a first lower speed envelope based at least in part on the first residual speed;
• determine an overall lower speed envelope based at least in part on the first lower speed envelope;
• determine an upper speed envelope;
• determine a target speed profile based at least in part on the first residual speed, the first residual speed position, the first lower speed envelope, and the upper speed envelope;
• determine a coast start point based at least in part on the target speed profile;
• and
• communicate the coast start point to the operator of the vehicle.

A non-transitory computer-readable storage medium comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

• receiving vehicle position data for a vehicle;
• determining a projected route based at least in part on the vehicle position data;
• determine a first speed change position and a first speed change target speed based at least in part on the projected route;
• determining a first residual speed and a first residual speed position based at least in part on the first speed change position and the first speed change target speed;
• determining a first lower speed envelope based at least in part on the first residual speed;
• determining an overall lower speed envelope based at least in part on the first lower speed envelope;
• determining an upper speed envelope;
• determine a target speed profile based at least in part on the first residual speed, the first residual speed position, the first lower speed envelope, and the upper speed envelope;
• determining a coast start point based at least in part on the target speed profile;
• and
• communicating the coast start point to an operator of the vehicle.
