Abstract

An apparatus comprising an interface, a memory and a processor. The interface may be configured to receive sensor data samples during operation of a vehicle. The memory may be configured to store the sensor data samples over a number of points in time. The processor may be configured to analyze the sensor data samples stored in the memory to detect a pattern. The processor may be configured to manage an application of brakes of the vehicle in response to the pattern.

First claim

The invention claimed is:

1. An electric vehicle, comprising:
a vehicle having an electric power source, a communication system, and a user interface system configured to receive input from one or more users travelling a vehicle route using the vehicle; and
a power management system for the electric power source able to determine information about an external environment of the vehicle, with the power management system configured to:
determine one or more future segments of the vehicle route, while the vehicle route is being travelled by the vehicle, before the vehicle has reached the one or more future segments, wherein each of the one or more future segments comprises a determined length;
before the vehicle has reached the one or more future segments, and without changing the vehicle route, redefine the one or more future segments as one or more alternative future segments in response to changes in the determined information about the external environment of the vehicle, wherein a total number of the one or more future segments is different from a total number of the one or more alternative future segments;
use the determined information to determine one or more calculated electric powers over the one or more alternative future segments of the vehicle route; and
calculate one or more speeds over the one or more alternative future segments of the vehicle route and act to apply the one or more calculated electric powers to the vehicle to travel along the one or more alternative future segments of the vehicle route at the one or more calculated speeds.

2. The vehicle of claim 1 , wherein the vehicle route is set based on a future destination determined by the power management system based at least in part using historical data associated with the one or more users, wherein the future destination is a destination at which the vehicle will be parked and turned off.

3. The vehicle of claim 1 , wherein the vehicle route is set based on a future destination determined at least in part using statistical destination logic.

4. The vehicle of claim 1 , wherein determining information about the external environment of the vehicle further comprises communicating with a remote database, and wherein the determined information about the external environment is selected from the group consisting of: an elevation of the vehicle, upcoming elevations of the vehicle, a location of a stoplight, a timing of a stoplight, a present angle of the sun, a predicted angle of the sun for an upcoming segment of the vehicle route, a current temperature, a predicted temperature for an upcoming segment of the vehicle route, a current air pressure, a predicted air pressure for an upcoming segment of the vehicle route, a time of day, a date, and a day of a week.

5. The vehicle of claim 1 , wherein the one or more calculated speeds are based at least in part on determined probable optimal speeds using historical route information, and wherein the probable optimal speeds are configured for optimal energy efficiency, within one or more constraints, of the vehicle on the vehicle route.

6. The vehicle of claim 1 , wherein the one or more calculated speeds are based at least in part on iteratively simulated speeds.

7. The method of claim 2 , wherein a last of the one or more alternative future segments includes the future destination.

8. The vehicle of claim 1 , further comprising, before the vehicle has reached any of the one or more future segments, adjusting one or more of the determined lengths of the one or more future segments in response to changes in the determined information about the external environment of the vehicle.

9. The vehicle of claim 2 , wherein the future destination is not explicitly provided by the one or more users.
