Abstract
A method of providing assistance to an internal combustion engine for a vehicle using an electric motor coupled to the engine is provided. The method comprises predicting a driving range based on historical driving range data. The historical driving range data includes one or more distances that the vehicle was driven during one or more previous driving cycles. The method further comprises selectively operating the motor to provide assistance to the engine at predetermined operating conditions of the engine. The assistance provided to the engine at one or more of the predetermined operating conditions is determined based at least in part on the predicted driving range.
Claims30
A method of providing assistance to an internal combustion engine for a vehicle using an electric motor coupled to the engine, the method comprising:
- predicting a driving range based on historical driving range data, wherein the historical driving range data includes one or more distances that the vehicle was driven during one or more previous driving cycles;
- and
- selectively operating the motor to provide assistance to the engine at predetermined operating conditions of the engine, wherein the assistance provided to the engine at one or more of the predetermined operating conditions is determined based at least in part on the predicted driving range.
A motor controller comprising:
- one or more processors configured to execute instructions stored on one or more computer-readable media, wherein the instructions are executable by the one or more processors to implement a method comprising:
- predicting a driving range based on historical driving range data, wherein the historical driving range data includes one or more distances that a vehicle was driven during one or more previous driving cycles;
- and
- selectively operating an electric motor to provide assistance to an internal combustion engine at predetermined operating conditions of the engine, wherein the assistance provided to the engine at one or more of the predetermined operating conditions is determined based at least in part on the predicted driving range.
A hybrid drive system for a vehicle comprising:
- an electric motor configured to provide assistance to an internal combustion engine to provide motive power for the vehicle;
- and
- a controller configured to control operation of the electric motor, wherein the controller comprises one or more processors configured to execute instructions stored on one or more computer-readable media, wherein the instructions are executable by the one or more processors to implement a method comprising:
- predicting a driving range based on historical driving range data, wherein the historical driving range data includes one or more distances that a vehicle was driven during one or more previous driving cycles;
- and
- selectively operating an electric motor to provide assistance to an internal combustion engine at predetermined operating conditions of the engine, wherein the assistance provided to the engine at one or more of the predetermined operating conditions is determined based at least in part on the predicted driving range.
