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.
Claims20
A method of electric vehicle operation, comprising:
- determining a plurality of segments of a vehicle route travelled by one or more users using a vehicle;
- determining information about an external environment of the vehicle, information about operational status of the vehicle, user command inputs to the vehicle, and one or more operational parameters of the vehicle;
- using the determined information to calculate one or more speeds over the segments of the vehicle route, wherein the one or more calculated speeds are configured to maximize energy efficiency of the vehicle within one or more constraints while travelling on the vehicle route;
- using a power management system of the vehicle, applying calculated electric power to the vehicle to travel along the segments of the vehicle route at the one or more calculated speeds;
- displaying the one or more calculated speeds using a user interface;
- and
- the power management system determining a future destination 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, wherein one of the one or more users is a driver, and wherein the future destination is determined at least in part using an identity of the driver that is one of inferred by the power management system and input by the driver.

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 of the vehicle;
- a power management system for the electric power source able to determine information about an external environment of the vehicle, information about operational status of the vehicle, one or more user command inputs to the vehicle provided via the user interface, and one or more operational parameters of the vehicle, with the power management system using the determined external environment information to calculate one or more speeds over a plurality of segments of a vehicle route, and acting to apply calculated electric power to the vehicle to travel along the segments of the vehicle route at the one or more calculated speeds;
- wherein the one or more calculated speeds are configured to maximize energy efficiency of the vehicle, within one or more constraints, while travelling on the vehicle route;
- wherein the user interface displays the one or more calculated speeds;
- and
- 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, wherein one of the one or more users is a driver, and wherein the future destination is determined at least in part using an identity of the driver that is one of inferred by the power management system and input by the driver.
