Abstract

Techniques or systems for managing vehicle velocity are provided herein. For example, a system for managing vehicle velocity may receive slope information associated with a driving environment of a vehicle. This slope information may be obtained by cross-referencing a global positioning system (GPS) location of the vehicle with a slope database, which may be used to map the GPS location to corresponding slope information. The GPS location may be obtained from an on-board GPS unit or a third-party GPS device, such as a GPS component of a mobile device. The system may retrieve a current velocity associated with the vehicle and adjust a velocity of a vehicle accordingly, such as by accelerating or decelerating the vehicle. The system may calculate an estimated velocity based on the current velocity and the slope information. In this way, vehicle velocity may be managed or controlled.
