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 information about an external environment of a vehicle, information about operational status of the vehicle, and user command inputs to the vehicle;
- determining a vehicle route with a GPS equipped user operated device while one or more users are using the vehicle;
- determining predicted future road condition information that can affect electric power use of the vehicle along the vehicle route;
- and
- using a power management system, the determined information, the determined vehicle route, and the predicted future road conditions to calculate electric power needed over the vehicle route and select at least one target speed along the vehicle route based on the calculated electric power;
- wherein the vehicle route is determined using a combination of multiple route segments, wherein the method further includes the power management system determining a first future segment of the multiple route segments while the one or more users are using the vehicle to travel the vehicle route and, before the vehicle has reached the first future segment, the power management system determining a second future segment of the multiple route segments, the second future segment located further from the vehicle than the first future segment;
- and
- wherein the at least one target speed is based at least in part on iteratively simulated speeds, and wherein the iteratively simulated speeds are configured to increase energy efficiency of the vehicle on the vehicle route by adjusting a plurality of speeds of the vehicle on the vehicle route without adjusting an average speed of the vehicle on the vehicle route.

An electric vehicle operable in combination with a GPS equipped user operated device able to determine a vehicle route, comprising:
- a vehicle having an electric power source, a communication system, and a user interface system capable of accepting user command inputs from one or more users of the vehicle;
- and
- 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, information relating to predicted future road conditions, and information from the GPS equipped user operated device, with the power management system set to calculate electric power and speed over one or more segments of the vehicle route and select at least one target speed along the vehicle route based on the calculated electric power;
- wherein the at least one target speed is based at least in part on measured energy efficiency of multiple prior trips by at least one of the one or more users driving the vehicle on the vehicle route;
- and
- wherein the at least one target speed is based at least in part on iteratively simulated speeds, and wherein the iteratively simulated speeds are configured to simulate a Plurality of trips of the vehicle on the vehicle route which use different amounts of energy by using different sequences of speeds without adjusting an average speed of the vehicle on the vehicle route.
