Efficient control of fuel consumption in cars

A method comprising:

• performing at intervals, by a processor located on a vehicle:
• receiving acceleration data from an accelerometer that is configured to measure acceleration of the vehicle;
• receiving orientation data from a gyroscope that is configured to measure orientation of the vehicle;
• combining the acceleration data and the orientation data to generate speed fluctuation and slope data for the vehicle;
• and
• transmitting the fluctuation and slope data to a controller of the vehicle, wherein the controller modulates a driver input to an engine throttle of the vehicle based at least in part on the speed fluctuation and slope data, and
• wherein the controller of the vehicle modulates the engine throttle of the vehicle by reducing a number of time that the throttle cycles within a time period.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by processing circuitry to cause the processing circuitry to perform:

• performing at intervals:
• receiving acceleration data from an accelerometer that is configured to measure acceleration of the vehicle;
• receiving orientation data from a gyroscope that is configured to measure orientation of the vehicle;
• combining the acceleration data and the orientation data to generate speed fluctuation and slope data for the vehicle;
• and
• transmitting the fluctuation and slope data to a controller of the vehicle, wherein the controller modulates a driver input to an engine throttle of the vehicle based at least in part on the speed fluctuation and slope data, and
• wherein the controller of the vehicle modulates the engine throttle of the vehicle by reducing a number of times that the throttle cycles within a time period.
