Description

RELATED APPLICATIONS

The present disclosure is related to and claims priority to U.S. patent application Ser. No. 15/966,556, filed Apr. 30, 2018, which claims priority to U.S. Provisional Application No. 62/492,257, entitled “SYSTEMS AND METHODS FOR EXTENDING VEHICLE RANGE TO MAXIMIZE OPERATION DISTANCE,” filed on Apr. 30, 2017, the entire disclosure of which is hereby expressly incorporated herein by reference.

FIELD OF THE DISCLOSURE

This disclosure relates systems for extending the range of a vehicle. More specifically, this disclosure relates to systems for extending the range of a vehicle when an estimated expected range is less than the distance of the vehicle from a target destination.

BACKGROUND

Vehicles are mobile machines that move people and/or cargo from one location to another. Due to varying intended uses, performance parameters, cost considerations. and evolving technology, vehicles—such as motor vehicles (e.g., cars, trucks, buses, etc.), watercraft (e.g., ships, boats, personal watercraft, etc.), and railed vehicles (e.g., trains, trams, etc.)—use various types of power plants to provide the motive force to move the vehicle. Power plants are machinery for supplying the power for a particular mechanical process, such as converting potential energy into mechanical energy to move the vehicle.

Power plants may include engines, motors, other power sources, and combinations thereof that may cooperate with related ignition, transmission, and other components of a vehicle. Engines may include compression-ignition engines (e.g., diesel engines), spark-ignition engines (e.g., gasoline engines, natural gas engines), gas turbines, jet engines, and combinations thereof. Motors can include electric motors or electric machines that convert electrical energy into mechanical energy, such as direct-current (DC) motors, alternating-current (AC) motors, and induction motors. Power plants may also include combinations of various types of engines and motors, such as conventional hybrid engines and flex fuel engines.

As the types of vehicles and their power plants become more diverse and rely on differing fuel (potential energy for the power plant such as chemical potential energy or stored electrical energy), not all target destinations, such as fueling stations or charging stations, may be able to resupply the vehicle being operated. Thus, operators of vehicles may find that they lack sufficient reserves to arrive at a target destination that has the proper fuel for the vehicle to resupply the reserve or tank.

Estimating the reserves of potential energy in a vehicle can become complicated by a variety of factors both internal and external of the vehicle. As fuel available at target destinations, such as fueling stations and/or charging stations, may vary and fuel for a particular power plant may be scarce along a route, operators may find that they do not have sufficient estimated fuel reserves to arrive at the next appropriate target destination.

A need therefore exists to address issues of extending the range of a vehicle when an estimated expected range is less than the distance of the vehicle from the target destination.

DETAILED DESCRIPTION

The embodiments disclosed below are not intended to be exhaustive or limit the disclosure to the precise form disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art may utilize their teachings.

As described briefly above, as fuel available at target destinations may vary and fuel for a particular power plant for a vehicle may be scarce along a route, an operator may find that they do not have sufficient estimate fuel reserves to arrive at the next appropriate target destination. FIG. 1 illustrates such a method for extending the range of a vehicle when an estimated expected range is less than the distance of the vehicle from the target destination.

One of ordinary skill in the art will realize that the embodiments provided, such as those in the figures, including FIG. 1, can be implemented in various hardware, software, firmware, and/or combinations thereof. Programming code according to the various embodiments exemplified can be implemented in any viable programming language such as C, C++, HTML, XTML, JAVA or any other viable high-level programming language, or a combination of a high-level programming language and a lower level programming language.

FIG. 1 shows an exemplary flow diagram for a method for extending a range of a vehicle. Method 100 may include receiving a first data, the first data being indicative of a distance of the vehicle from a target destination (step 102) and receiving, a second data. the second data being indicative of a level of potential energy of an energy source for a power plant of the vehicle (step 104).

The first data is not particularly limited and may include various types of data that may indicate or be used to indicate the distance of the vehicle from the target destination. Thus, as used herein, data that is “indicative of a distance of the vehicle from a target destination” may be data that contains the distance from the vehicle to the target destination or may be used by the vehicle in conjunction with other data for calculating the distance from the vehicle to the target destination.

For example, in some embodiments, the data may be the location of the target destination and other systems on the vehicle may calculate the actual distance from the vehicle to the target destination.

In other embodiments, the vehicle's location and the target destination's location may be calculated by a processor physically removed or separate from the vehicle. In such embodiments, a processor may calculate the distance of the vehicle from the target destination. The first data may then be sent to the vehicle via wireless technology or pulled by the vehicle via wireless technology, for example, from a cloud.

The first data indicative of a distance of the vehicle from a target destination may also include at least one of a location of the vehicle, a location of the target destination, a velocity of the vehicle, an acceleration of the vehicle, a route from between the position of the vehicle and the target destination, an elevation change along the route, a surface condition of the route, or combinations thereof.

As used herein, the term “wireless communication” is not particularly limited and may include any known method of wireless communication by computing devices, such as radio, infrared, microwave, wireless local area network, or Wi-Fi, or short-wavelength ultra-high frequency radio waves, such as Bluetooth.

The second data may be data that is indicative of a level of potential energy of an energy source for a power plant of the vehicle. The data is not particularly limited and may include any data for an energy source that is used by a vehicle. For example, with vehicles having internal combustion engines, sensors such as fuel or pressure sensors, may detect the remaining amount of fuel (potential energy) in the energy source (such as a fuel tank) and may send that data as the second data to the processor.

As used herein, the potential energy stored in the vehicle is not particularly limited and may vary based on the power plant or power plants used in the vehicle. For example, the potential energy may include electrical potential energy and/or chemical potential energy (e.g., gas). Thus, the level of potential energy may include the state of charge of a battery (for electrical potential energy) and/or include a fuel level or amount (for chemical potential energy). The fuel is not particularly limited and may include at least one of an alcohol, a diesel fuel, a gasoline, a natural gas (liquid or compressed natural gas), hydrogen, propane, other hydrocarbons, or mixtures thereof.

Method 100 may also include receiving an operating parameter indicative of estimated future energy usage of the power plant (step 106), estimating, by a processor, an expected range of the vehicle based on the second data and the estimated future energy usage of the power plant (step 108), and adjusting, by a controller in electrical communication with the power plant, a performance parameter of the power plant to extend an actual range of the vehicle when the estimated expected range is less than the distance of the vehicle from the target destination (step 110). In various embodiments, the target destination may be a fueling station and/or charging station to resupply the vehicle with either chemical potential energy (fuel) and/or electrical potential energy (supply electricity to recharge electrical storage units, such as batteries).

In some embodiments, the estimation of the expected range may include additional third data. Third data may help better inform the estimation of the range of the vehicle and may be data from the vehicle itself, data from other vehicles, data from the route, and/or environmental condition data. Third data may include historical potential energy usage of the vehicle, historical potential energy usage of other vehicles, a weight of a payload, current traffic conditions, estimated future traffic conditions, current weather conditions, future weather conditions, or combinations thereof.

The operating parameter is not particularly limited and may be received by a variety of sensors or other data that monitor the power plant. The operating parameter and performance parameters may include at least one of torque, instantaneous power, idle limits, speed. acceleration, change of acceleration, or any combination thereof. Thus, in some embodiments, methods may also include the step of instructing the controller, by the processor, to adjust the performance parameter. In some embodiments, the operating parameter may be the same parameter as a performance parameter, or in other embodiments, they may be different.
