Abstract
A system includes a power source to generate power to propel the vehicle, and a speed sensor to detect a current speed. The system also includes a camera to detect image data corresponding to a current roadway, and a GPS sensor to detect location data corresponding to a current location of the vehicle. The system also includes an ECU. The ECU is designed to determine a target vehicle speed based on at least one of the image data or the location data. The ECU is also designed to calculate an energy-efficient acceleration pattern to accelerate the vehicle from the current speed to the target vehicle speed based on a goal to minimize energy usage of the power source. The ECU is also designed to control the power source to accelerate the vehicle from the current speed to the target vehicle speed using the energy-efficient acceleration pattern.
