Automobile-speed control using terrain-based speed profile

摘要

Aspects of the present disclosure are directed towards hysteresis engaged vehicle cruise control apparatuses, and systems and methods that facilitate energy efficiency as a function of external energy obstacles. The method and system includes an adaptable terrain-based speed profile and terrain-based work function for maintaining a vehicle at a desired speed and selected speed range. The speed profile further includes a terrain-based driving preference associated with an identifier that identifies a particular driver and driving profile. Vehicle-related data is generated with regard to energy efficiency obstacles, and vehicle speed is automatically adjusted based on this data to facilitate fuel economy. In certain embodiments, vehicle-related data is sent to a cloud-computing system for processing. In other embodiments, the desired speed and terrain-based speed profile is influenced by user or external inputs.

主权项

1. A method comprising:
selecting at least one of a desired speed and a selected speed range for operation of a vehicle by using circuitry in the vehicle which circuitry includes one of programmable logic circuit, discrete logic circuit, computer circuit, and a combination thereof; the circuitry, in response to the selection, accessing a terrain-based speed profile and a terrain-based work function for the vehicle for maintaining the vehicle at the desired speed, wherein the accessed terrain-based speed profile and the terrain-based work function correspond to a selected speed range for the desired speed and for a current driving mode, a terrain-based driving preference for a type of driving, the type of driving accounting for an amount of hysteresis in adjusting the speed of the vehicle relative to the desired speed; and the circuitry accessing the status of expected energy-efficiency obstacles associated with a roadway corresponding to the terrain-based speed profile, and in response, causing the vehicle to automatically adjust the speed of the vehicle relative to the desired speed to facilitate fuel economy based on the terrain-based speed profile and the terrain-based work function.
