The present disclosure relates to the field of electrical traction motors for vehicles.
Vehicles, such as automobiles, may comprise an internal combustion engine (ICE) and/or an electrical traction motor (ETM). The ICE or ETM may be connected to a transmission, thereby driving wheels of the vehicle in a rotational motion that advances the vehicle. When using an ETM, the vehicle and/or engine may, for example, comprise power electronics for controlling the motor (such as an inverter with an integrated controller) and/or energy storage (such as a high-capacity battery). Brakes incorporated into the wheels may be operated by a lever in the vehicle, such that when the lever is pressed the brakes in the wheel are actuated and the vehicle is slowed down and/or stopped. When an accelerator pedal is pressed, a signal may be transferred to the engine or motor to apply more power to the wheels. The engine or motor may be located within the vehicle chassis, such as under a front or rear bonnet. The wheels may be attached to a wheel hub using wheel lugs, and the wheel hub may comprise, for example, the drive shaft and/or brakes. Tires may be attached to rims of the wheels.
The following is a short summary of some of the inventive concepts for illustrative purposes only and is not an extensive overview, and is not intended to identify key or critical elements or to limit or constrain the inventions and examples in the detailed description. One skilled in the art will recognize other novel combinations and features from the detailed description.
According to aspects disclosed herein, components of a vehicle, such as wheels, may comprise a self-contained traction system, such as comprising energy harvesting components, electric motors (or equivalent conversion devices), energy storage components, power/control electronics and/or controllers. Sensors, such as in communication with the controllers of the wheels, may be placed at the operator controls, and the sensor readings may be used by the wheel's controller to choose between using the self-contained traction system and using the vehicle traction system, such as an internal combustion engine (ICE). For example, the wheels of a vehicle may be replaced with traction motor wheels that comprise energy storage and electronics/mechanics for transfer of the stored energy to the wheel during certain conditions, such as during slow speeds or a traffic jam. For example, a mechanical flywheel incorporated into the wheel may store energy and act as a motor.
The flywheel may act as a rotor, where the stator may be the wheel hub and/or wheel rim. The wheel may transfer the angular momentum of the flywheel to the vehicle using the operation of the electromagnets in sequence. For example, the wheels of a vehicle may comprise batteries, electronics, and an electric hub motor/generator, where the hub motor/generator stores electrical energy in the battery and later uses the electrical energy to assist in advancing the vehicle. For example, the internal combustion engine (ICE) and/or transmission of a vehicle may be replaced with an electrical traction motor, electronics, and a battery occupying the same space as the ICE and/or transmission. In this example, the same connectors to the operator controls may be used, thereby converting the vehicle to a battery electric vehicle or hybrid powertrain.
These and other features, aspects, and advantages of the present disclosure will become better understood with regard to the following description, claims, and drawings. The present disclosure is illustrated by way of example, and not limited by, the accompanying figures. In the drawings, like numerals reference similar elements.
The accompanying drawings, which form a part hereof, show examples of the disclosure. It is to be understood that the examples shown in the drawings and/or discussed herein are non-exclusive and that there are other examples of how the disclosure may be practiced.
In internal combustion engine (ICE) vehicles, the incorporation of electrical traction motors for improved efficiency may be challenging. For example, the vehicle might not be designed for such modifications. For example, a retrofit device cost including installation may cost more than a new electric vehicle (EV). The solutions disclosed herein provide a self-contained energy conversion and storage system, which may replace existing components of a vehicle, thereby adding an electrical traction system. Self-contained electrical traction motors, such as a vehicle traction device, may be incorporated into a vehicle engine, transmission, drivetrain (e.g. transaxle, differential, shaft, and/or joints), or wheels to convert an ICE vehicle into a hybrid vehicle, reduce emissions on ICE vehicles, or extend the range of a vehicle. For example, an aftermarket set of wheels for the vehicle may comprise electric motors/generators, electronics, and batteries for energy storage. For example, a vehicle transmission may be replaced with a transmission incorporating one or more electric motors, electronics, and batteries within the replacement transmission. For example, an ICE and transmission may be replaced with an electric motor, electronics, planetary gear, and battery.
Aspects of the disclosure relate to a vehicle traction device, such as a vehicle wheel, rim, wheel and tire combination, etc., where the vehicle traction device comprises at least one energy storage component, at least one traction component, at least one sensor, and a controller. For example, the energy storage component may be a battery, a super-capacitor, a flywheel, etc. At least one traction component, such as a traction motor, may be engaged to propel the vehicle forward, such as by a controller monitoring sensor(s), sensor(s) connected to an engagement control circuit, etc. Sensors may be incorporated into the user controls, such as pressure sensors, velocity sensors, yaw-rate sensors, position/location sensors, acceleration sensors, gyroscopic sensors, piezoelectric sensors, etc., and a circuit or controller monitoring the sensors may determine to engage the traction device to propel the vehicle forward.
For example, the controller is configured to monitor sensor values, and responsive to the sensors values, direct the conversion of energy between the energy storage component (i.e. battery) and the traction component (i.e. electric motor). For example, the energy storage component may be a flywheel that stores kinetic energy, and the kinetic energy may be transferred to or from the vehicle rim and tire using magnets, selectively activated to transfer energy using magnetic attraction and repulsion.
For example, at least one acceleration sensor may be connected to the gas pedal, such as a pressure sensor, a motion sensor, an accelerometer, a piezoelectric sensor, etc. For example, at least one deceleration sensor may be connected to the brake pedal, such as a pressure sensor, a velocity sensor, a yaw-rate sensor, a position/location sensor, an acceleration sensor, a gyroscopic sensor, a piezoelectric sensor, etc. The acceleration sensor may be responsive to an operator input, and when the input is applied, the traction component is signaled to transfer energy from the energy storage component to increase a velocity of the vehicle. Similarly, one or more deceleration sensors may be responsive to an operator input, and when said the input is applied, the traction component is signaled to transfer energy to the energy storage component from the forward moment of the vehicle, thereby reducing the vehicle velocity.
When more than one vehicle traction device is used on a vehicle, sensors may assist in the coordination and operation of the devices. For example, a yaw rate sensor may provide a measurement of the rotation around a vertical axis to assist in providing power to each vehicle traction device. For example, a pressure sensor may provide a measurement of the brake fluid pressure in the master brake cylinder. For example, a transverse acceleration sensor may provide a measurement of the transverse acceleration, such as when driving with a crosswind, or along a curved stretch of road. For example, four speed sensors may measure the speed of each wheel. For example, a steering wheel angle position sensor may provide a measurement of the steering angle in response to an input from the driver. For example, an electronic control unit (ECU) may perform processing of the sensor signals and calculate as power to provide to each vehicle traction device and control signals to other vehicle components, such as actuators.
A hydraulic power unit may implement commands of the ECU. For example, a hydraulic power unit may control the respective brake cylinder operation independently of the input from the driver. For example, brake pressure may be monitored by the hydraulic power unit, or the ECU. For example, the hydraulic power unit may receive a command to pre-charge a pump/charging piston unit of the hydraulic power unit. For example, when the brake is not actuated by the driver, the hydraulic power unit pressure may build-up pressure in the brake cylinder to allow enough pressure for breaking operation
An energy transfer component may be used to convert kinetic energy between the traction component and the vehicle. For example, a motor, a generator, a combined motor and generator, an induction charging system, and/or a magnetic-flywheel converter system may be used to convert between kinetic and electrical energy. Some energy harvesting methods may be used to collect energy, such as solar, regenerative braking, induction charging, etc., and the energy may be stored in the energy storage device. For example, an acceleration of the vehicle, at least in part, may be provided to increase the state of charge of the energy storage device, such as by using a clutch and generator.
An operator device, such as a gas pedal, a brake pedal, etc. of a vehicle, may be used to signal the conversion of electrical energy between the at least one traction component (such as an electric motor) and the at least one energy storage component (such as a battery).
When a vehicle has power steering enabled by an ICE power, and the ICE is shut down when axillary traction motors are enabled, a steering sensor may be used. For example, a steering sensor (such as a pressure sensor, a velocity sensor, a yaw-rate sensor, a position/location sensor, an acceleration sensor, a gyroscopic sensor, a piezoelectric sensor, etc.) may be responsive to an operator steering input. When the operator steering input is received, a controller may be signaled to enable auxiliary power supply to a power steering energy device (such as from a battery to the power steering hydraulic pump, etc.) For example, using a relay to supply power to the power steering pump.
A vehicle traction device (motor, energy conversion, energy storage, etc.) may be incorporated into a drivetrain component of the vehicle. For example, the traction motor may be incorporated into a differential, a gearbox, a driveshaft, a transmission, an ICE, etc. For example, an electric motor, control electronics, and energy storage may be incorporated into an axle to provide power to the wheels, such as an e-axle for providing supplemental power to the wheels.
The energy storage component(s) may be a secondary battery (such as Li-ion battery, etc.), a flywheel, a compressed gas energy storage, a super-capacitor, a fuel cell, etc. The vehicle traction device may be configured for a land vehicle, such as a car, bus, van, pickup, off-road vehicle, truck, earth-mover, tractor, trailer, etc. The vehicle traction device may be incorporated into a wheel, and the wheel configured to propel a specific vehicle make and model during a traffic jam for a limited time (i.e. up to the limit of the energy storage component). The vehicle traction device may be included in a kit, such as a kit of four vehicle traction wheels configured for a Smart® Fortwo®. For example, the kit may include four vehicle traction devices, sensors, and a control unit, where the sensors are installed on the vehicle controls, and the control unit collects the sensor data and sends operational commands to the vehicle traction devices.
Energy storage may be added outside of the wheels. For example, the combined volume of the energy storage components, such as batteries, may be physically larger than the space available in the wheel, and a portion of the batteries may be located outside the wheel. For example, a battery may be added to the energy storage of a traction device by using an electrical conductor and connector. For example, an additional battery may be located in a compartment adjacent to the wheel.
Energy storage may be used during a driving for providing power to auxiliary vehicle systems, such as cooling, heating, wipers, etc. For example, an energy storage component external to the wheels may be added to an ICE vehicle to provide power to the power steering when the ICE is shut down during a traffic jam. For example, an energy storage component external to the wheels may be added to an ICE vehicle to provide power to the air conditioning when the ICE is shut down during a traffic jam. Similarly to these examples, power may be provided from an additional energy storage component to the heater, wipers, power brakes, or other vehicle components that may be needed during the operation of the traction device(s)
Besides increasing fuel efficiency for ICE vehicles, the vehicle traction device may be incorporated into other kinds of vehicles, such as hybrid (HEV) or electric vehicles (EV). As used herein, the term vehicle means an ICE, HEV, EV or other land vehicle with any combination of motors/engines. A vehicle traction device may allow increasing the range or efficiency of a vehicle so that better utility may be made out of each charge. For example, the vehicle traction device may increase the range of a vehicle. For example, the vehicle traction device may increase the fuel efficiency of a vehicle to comply with fuel efficiency regulations, such as city regulations, local regulations, regional regulations, country regulations, and/or export regulations.
A traction device may comprise a geographic location sensor, such as a global positioning device (GPS) sensor, and the controller of the traction device may alter the operation of the traction device based on input from the location sensor. For example, when a vehicle enters a particular region that requires a change in vehicle emissions, such as low emission zones, zones with certain environmental regulations (noise and/or pollution), etc., the control unit may apply the traction device(s) to propel the vehicle, and thereby reduce the emissions for the vehicle. For example, a company may purchase a fleet of vehicles from two or more brands, and use a GPS sensor incorporated into a traction device to monitor the combined locations of the fleet vehicles of the two brands.

As used herein, the terms controller and controller circuit mean an electronic component configured to implement one or more functions, such as a method and/or a rule, to operate and control one or more other electronic circuits. For example, a controller may be a central processing unit, a micro-processor, an embedded controller, a digital hard-wired logic circuit, an application specific instruction set processor, an application specific integrated circuit, a multi-core processor, and/or a field programmable gate array (FPGA). The controller (or controller circuit) may interpret and execute instructions that, for example, may be stored in memory (such as hardware-based digital storage, RAM, ROM, optical disk) accessible by the controller, stored as software in a repository and/or hardwired in digital logic or an FPGA. For example, an apparatus may comprise a controller (e.g., a processor) and memory storing instructions, that when executed by the controller, cause the apparatus to implement one or more functions, such as those described in

Indigenous components 210 of the engine and/or transmission 200 may be replaced, modified, or removed. For example, when the electrical traction motor replaces the ICE, there might not be need for a transmission. In this example, the ICE is replaced and the transmission is modified to a planetary gear that corresponds to the operational characteristics of the electrical traction motor. In a replacement wheel example, the functions of the wheel may be included in the replacement component, such as a rim, a tire, a brake disk, and/or a central bearing.

The sensors 410, 412, 414 may record operator input to the vehicle controls and send the sensor values to a controller (such as a central processing unit or CPU) as at 404. These sensor values allow determining when the vehicle is to be operated in braking mode, when energy from the vehicle deceleration is converted to electrical energy in battery 404, such as by using a generator. The sensors allow determining when the vehicle is to be operated in electric motor mode, such that hub traction motor 408 supplies forward motion to the vehicle by engaging lock pins 402 and converting electrical energy of battery 404 to forward motion. In some circumstances, such as a traffic jam and/or stop-and-go traffic, it may be desirable to stop the operation of an ICE, and use only hub traction motor 408 for forward propulsion. In this case, the auxiliary components, such as power steering and/or power brakes, may be non-operational. In these cases, when steering sensor 410 registers an operator input to the steering and when the vehicle is operating in electrical traction motor mode, the controller may signal to a component in the engine area, such as under the bonnet, that a power steering pump is to be operated to allow operator control of the vehicle steering. Similarly, brake sensor 412 may determine that power steering should be turned on.

Many vehicles may be used in situations where the efficiency of the ICE is not good, such as when idling and/or during stop-and-go traffic, but no alternatives exist. For example, a Smart™ Fortwo™ vehicle may be used for urban driving only, and during a traffic jam, the ICE of the vehicle may operate at inefficient gasoline consumption levels. Retrofitting vehicles for hybrid or as battery electric vehicles (BEVs) is costly and may require extensive rewiring of the chassis, sometimes external to the vehicle, to accommodate the electric energy storage, for example in place of the gas tank. By incorporating all components of the electrical subsystem within the component being replaced, such wheels, engine, and/or transmission, some problems with retrofitting the entire vehicle are avoided. The electrical system incorporated into the components may be a simplified system with minimal performance specifications for the situations described above, such as low energy output during traffic jams, and/or cruising, and may provide sufficient energy output to achieve a significant savings in gasoline consumption.
Electrical traction motors used in electrical vehicles may typically comprise power electronics and a battery separate from the electric motor, making the direct replacement of an ICE with an electric motor challenging to fit all the components into the space previously occupied by the ICE. In modular designs, such as the designs used for commercial vehicle configuration offered by Bosch™, Voith™, and others, modules may be used, for example, for the motor, battery, and/or electronics. This allows combining the modular components for multiple vehicles/solutions/applications. In many private passenger electric vehicle designs, first generation motor designs may use modular components to decrease the development costs and time-to-market, but subsequent generations may use integration of the components for increased cost efficiency.
Integration of the inverter with motor and gear may allow cost reduction at the expense of maintenance costs, for example replacing a complete engine when a single component, such as the inverter, fails. The size, shape, and weight distribution of the EV motor may require non-linear shapes, such as heavier components being situated lower in the vehicle for better cornering ability, and lighter components, such as electronics, may be situated higher in the vehicle. Similarly, the location of components in an electric-wheel (e-wheel) may be positioned such that the lighter weight components are further distant from the axis of rotation, thereby producing, for example, a lower moment of inertia and/or less unsprung weight.
In some applications, such as marine electric motors, the requirements for protection from the marine environmental may be different for power electronics and the electric motor itself. For example, a marine ICE motor may be converted to use an electric motor or a hybrid motor that incorporates energy storage, and stores energy when the marine vehicle is slowed down, and uses the stored energy for propelling the marine vehicle. For example, the stored energy of the marine vehicle is used when docking or moving slowly.
Two motors with different operating characteristics may be been used together in a vehicle to generate more beneficial torque profiles of the motors. For example, a first electric motor (incorporated in a first wheel etc.) has an operating speed at peak efficiency of 1000 rotations per minute, and a second electric motor (incorporated in a second wheel etc.) has an operating speed at peak efficiency of 3000 rotations per minute. The first motor may be used for low speed movement and the second for high speed movement, thereby working at top efficiency at both low and high speeds. For example, a first motor has a very high torque at low speed and a second motor has medium torque at high speed. An off-road vehicle that may use this example may use the first motor when being driven in low gear and at low speed to overcome obstacles, and the second motor when being driven on the freeway. Similarly, the motors may be in two wheels for each type of motor, for example, two low speed motors in the front wheels and two high-speed motors in the rear wheels.
Configuring the electric motor to include the power electronics and other mechanics as a natural extension of the motor body may allow easier incorporation of the motor design into a vehicle design. For example, retrofit electric motors for specific purposes, such as a motor integrated into an aftermarket wheel for stopping the operation of an ICE during a traffic jam, may benefit from integrated electronics, gears, and/or multiple motors for different powers/speeds. For example, the electric motor, mechanics, energy storage, electronics, and kinetic charger may be incorporated into an aftermarket wheel/rim (e-wheel), capable of fitting many makes and models of vehicles, and accepting standard tires. Incorporating acceleration and brake pedal sensors, such as converting the pedals into two-stage pedals, light press for electric motor and heavy for ICE, etc., may allow vehicle motion without operating ICE (or keeping motor at idle in case of power steering/brake needs) and an incorporated battery during braking.
The e-wheel can be sold as an aftermarket product, and may be targeted for non-EVs to benefit from EV tech based on the time needed during stop and go traffic. Alternative configurations may include, for example, a replacement engine, a replacement transmission, a replacement transaxle, a replacement driveshaft, and/or a replacement differential. Braking friction may be transferred to a generator using lock pins in the circumference of the wheel, between the motor and rim. Lock pins may be electromechanically engaged to assist in transferring the kinetic energy between the electric motor and the wheel (such as during traction or braking). Sensors values may determine when a transition from soft (regenerative) braking to hard braking is requested by the operator.
For example, sensor values indicating moderate (less than 75%) acceleration may configure the vehicle to charge the battery by converting the vehicle's kinetic energy into electrical power. For example, light pressure on a brake pedal sensor may indicate to the vehicle's controller to configure the components to use regenerative braking to store energy for later use. A steering sensor may be used, for example, to auto-turn on the ICE when pressure is applied to the steering wheel, brake pedal, accelerator pedal, similar to the algorithms used for cruise control, and/or auto-shutoff. When an operator attempts to make a change to the vehicle, such as a change that requires the ICE to turn on, the auto-turn on device may start the ICE. This may make the turn-off transparent to the operator. Light pressure on an accelerator pedal may disengage lock pins and configure the vehicle to use the hub motor—for both slow traffic (such as in a traffic jam) and highway cruising (instead of ICE). Optional ICE auto-shutoff may need to address solutions for ancillary power such as power steering, power brakes, and/or air conditioning, when the ICE is off or idle (such as not supplying sufficient power for the equipment).
A flywheel for energy storage may incorporate a double sided mechanism, comprising outboard EMs and permanent magnets (laterally closer to the outer edge of the vehicle), and inboard ones (laterally closer to the vehicle central line). Each side of the flywheel may comprise lock pins for locking the flywheel to the wheel, hub, and/or rim. The inner side of the flywheel is connected to the outer side with an electronic controlled variable transmission that allows the two sides to rotate at different speeds while preserving angular momentum. For example, the rotational speed of inner side may be slowed down using the variable transmission (speeding up the outer side) to match the rotational speed of the axle. For example, the inner pins lock to the wheel axle, and the variable transmission may be used to transfer the momentum of the flywheel to the axle rotation. Energy may be stored as kinetic energy in the flywheel mechanism, such as a vacuum encased flywheel with magnetic bearings, and induction magnets surrounding the flywheel may convert mechanical energy of the vehicle wheel to kinetic rotational energy of the flywheel, and vice versa.
Two flywheels turning in opposite directions may be used to reduce gyroscopic forces. Transfer of wheel rotation energy to a flywheel and back may be done by magnetic fields, such as used in various kinds of electric motors. Electromagnets placed around the rim may pull or push the permanent magnets in the flywheel according to a specific order, depending on the relative rotating speeds and the configuration desired.
In a rotating frame of reference, such as a frame of reference of the flywheel 506 of
Increased wheel and/or tire weight may be offset with shock absorbers and springs configured for the different wheel weight. The higher density (such as weight) components may be closer to the center of the wheel so that there is less of a moment arm on the suspension as well as less rotating weight and/or mass. Counter rotating flywheels may be used to reduce the effect of the gyroscopic forces of a rotating flywheel, and the connection between the counter rotating flywheels may be, for example, mechanical, such as mechanical gears; and/or magnetic, such as using magnetic forces or induction. Sensors on the electromagnets may detect both the angular position and speed of the flywheel to determine when more energy may be applied to the flywheel. A smartphone application may assist to control, for example, the flywheel, hub motor, and/or electric motor. For example, operational parameters of the flywheel may be viewed on the smartphone, such as the amount of energy stored, and a voice command may be received by a microphone of the smartphone, such as a command to increase the amount of stored energy by increasing the energy harvested from the wheels motion induced by the ICE.
A controller of the flywheel may access sensors outside of the wheel, such as by using Bluetooth, to determine when to use the stored energy. A communication link, such as Bluetooth, Wi-Fi, CANbus, and/or RS-485, may access other vehicle sensors, such as the acceleration and braking sensors on the pedals, visual/optical sensors on vehicle alert devices (such as Mobileye® devices), GPS sensors, traffic sensors, and/or internet data repositories. Similar communication links may be used between the wheels, or between the wheels and the control unit.
The aspects disclosed herein may be used for a full EV conversion for old cars with no engines, using string batteries snaked into the fuel tank, plugged in at the motor/inverter, wires strapped to body outside vehicle (to transfer power from the batteries in the fuel tank to the engine), and an engine-to-motor mechanical conversion kit. Alternatively, batteries may be incorporated in the vehicle to replace the transmission and/or transaxle.
Following are calculations for use of auxiliary electrical traction motors in a traffic jam. For the calculation, it is assumed that the traffic jam is over a distance of 10 kilometer (km) and the vehicles are travelling at 10 km per hour (km/h), such as during a one-hour traffic jam. For example, current electrical traction motor efficiency at 10 km/h may be 130 watt-hour (Wh) per km (Wh/km), so a total capacity of 1300 Wh is needed. For Li-ion batteries, energy density may be about 260 Wh/kilogram (Kg), so the batteries will weight 5 Kg, or 1.25 Kg per wheel. If a flywheel energy storage is used the density is 130 Wh/Kg, and therefore, a based flywheel system would weigh 10 Kg, or 2.5 Kg per wheel. In addition, a 200 W solar panel on roof may supply enough power for the vehicle motion during a traffic jam. A solar car cover may also be incorporated into the system. One option for the design of the e-wheel incorporating the aspects disclosed, is shown in the following table:
To confirm that this extra weight is acceptable, wheel and tire weight variations have been analyzed and simulated. For example, an original equipment (OE) BMW 3 series wheel weighs 20.5 pounds each, while an OE Michelin Energy MXV4 Plus tire weighs 22.5 pounds each, arriving at a total of 43.0 pounds for each tire including the wheel. Lightweight wheels on the other hand may weigh as little as 17 pounds each, reaching a total of 38.5 pounds per wheel plus tire (2 Kg less). Heavyweight wheels and tires may together weigh 48.5 pounds (about 3 Kg more than stock, 5 Kg more than lightweight). Wheels with larger rims may weight more, such as 54 pounds for wheels with 19″ rims versus 40 pounds for wheels with 15″ rims (7 Kg difference).
In a second scenario, an electrical traction motor has a power density of 1.5 kW/Kg, which is about 2 horsepower (hp)/Kg. Below 5 km/h, the efficiency may be 100 Wh/km, and at a speed of 10 km/h, the efficiency may be 50 Wh/km. For a 10 km traffic jam, the vehicle will need about 500 Wh of battery capacity (or energy storage of 125 Wh in each wheel). Thus a 750 W motor per wheel will produce about 1 hp at each wheel and weigh 500 grams per wheel. Consequently, a low efficiency 1.5 hp motor for traffic jams in each wheel may weigh up to 1 Kg, 500 Wh of energy storage may weigh 2 Kg, structural components may weigh 1 Kg, and electronics may weigh 1 Kg. So totals for each wheel are shown in the following table:
When a lightweight rim, wheel, and tire are used for an auxiliary traction device, the conversion kit may weigh less than or equal to the OE wheel and tire combination.
Sensors may be used for the operator controls, such as gyroscopic sensors, motion sensors, speed sensors, global positioning system sensors, optical sensors, and/or magnetic field sensors. The sensors may be located at the interface between a vehicle control and the operator, such that when the operator operates the vehicle, the dual sensors and controls may allow the controls to be a direct management of the ICE and the sensors allow a fly-by-wire control with the electrical traction motor and components.
Here, as elsewhere in the specification and claims, ranges may be combined to form larger ranges.
Specific dimensions, specific materials, specific ranges, specific resistivities, specific voltages, specific shapes, and/or other specific properties and values disclosed herein are example in nature and do not limit the scope of the present disclosure. The disclosure herein of particular values and particular ranges of values for given parameters are not exclusive of other values and ranges of values that may be useful in one or more of the examples disclosed herein. Moreover, it is envisioned that any two particular values for a specific parameter stated herein may define the endpoints of a range of values that may be suitable for the given parameter. For example, the disclosure of a first value and a second value for a given parameter can be interpreted as disclosing that any value between the first and second values could also be employed for the given parameter. For example, if parameter X is exemplified herein to have value A and also exemplified to have value Z, it is envisioned that parameter X may have a range of values from about A to about Z. Similarly, it is envisioned that disclosure of two or more ranges of values for a parameter (whether such ranges are nested, overlapping or distinct) subsume all possible combination of ranges for the value that might be claimed using endpoints of the disclosed ranges. For example, if parameter X is exemplified herein to have values in the range of 1-10, or 2-9, or 3-8, it is also envisioned that Parameter X may have other ranges of values including 1-9, 1-8, 1-3, 1-2, 2-10, 2-8, 2-3, 3-10, and 3-9.
