Fig. Figure 2 represents a block diagram containing components of an embodiment of a vehicle control system that includes the electricity optimization system of the present disclosure. DETAILED DESCRIPTION OF EXAMPLE FORMS OF EXECUTION
[0011] Existing electrical systems in vehicles use various step-up or step-down mechanisms to control and adjust the voltage supplied to each vehicle component. Such mechanisms are inefficient, and such a system results in wasted electricity. Instead of sending the same amount of power to each component and then adjusting the voltage individually at each component, various embodiments of the present disclosure provide an efficient system for supplying the optimal voltage to each vehicle component, thereby optimizing electricity generation and use.
[0012] In particular, various embodiments of the present disclosure provide a system and a method for optimizing electricity generation by using multiple voltage setpoints to operate vehicle components at the optimal voltage level based on their loads and for setting, monitoring and regulating the temperature for the operation of each component.
[0013] By providing multiple voltage setpoints for each vehicle component at the DC-DC converter, the electrical optimization system of this disclosure provides the optimal voltage for each component without using a step-up or step-down mechanism. The DC-DC converter is a more efficient source for controlling the power output to each component. The DC-DC converter can send the optimal voltage directly to each component via the voltage setpoints. Furthermore, because the total power is delivered to the various components through the DC-DC converter, the DC-DC converter can be designed to determine the optimal power output for the generator.In particular, instead of the generator being designed to output a standard voltage and current, the DC-DC converter can determine that the optimal output for a given system may be higher or lower, allowing power to be delivered more efficiently to each component. Such a configuration enables the electrical optimization system to efficiently power the various components of the vehicle.
[0014] In one embodiment, the electrical optimization system and method includes increasing the number of voltage setpoints in the vehicle to maximize power consumption efficiency. The voltage setpoints provide an optimized voltage level at which the connected component should operate. Increasing the number of voltage setpoints in the vehicle provides an optimized voltage level for multiple components and allows the electrical management system to distribute power to operate each component in the most energy-efficient manner.
[0015] As in Fig. As shown in Figure 1A, the electricity optimization system 100 in this embodiment includes a generator 102, a high-performance storage device 104, a DC / DC converter 106 with multiple voltage setpoints 108a, 108b, 108c, 108d, and a high-energy storage device 110.
[0016] The generator 102 produces power for various loads in the vehicle. A load refers to a system or component in the vehicle that draws power. A vehicle contains various high-power loads 114 and lower-power loads 116. In certain embodiments, this generator 102 can be an alternator, a solar panel, or another machine that produces electricity. In certain embodiments, the generator can also operate in reverse as a motor to start the power unit or to move the vehicle. In this embodiment, a standard 12-volt electrical system of the vehicle is replaced by a generator 102 that operates at 19 volts. The generator 102 is connected to the high-power storage device 104.
[0017] The high-power storage device 104 receives and stores the voltage output of the generator and regulates the output voltage from generator 102 to eliminate any transients in the vehicle's power generation. In certain embodiments, this high-power storage device 104 is a battery. In certain embodiments, the high-power storage device 104 is a capacitor. In certain embodiments, the high-power storage device 104 is capable of receiving up to 20 volts. In this embodiment, the high-power storage device 104 is connected to various controllers 112 that connect the vehicle's high-power loads 114 to the high-power storage device 104. Through these controllers 112, the high-power storage device 104 provides high-voltage power to the high-power loads 114.For example, high-power loads 114, such as electric compressors, electric heaters, power steering systems and electric pumps, require high power outputs from the high-power storage device 104.
[0018] The high-power storage device 104 can also be used to power various components in the vehicle that do not require high power. In particular, in this embodiment, the high-power storage device 104 is also connected to a DC-DC converter 106. A DC-DC converter 106 can be used to convert a high voltage from a high-voltage power source 104 into a low voltage for other vehicle components, such as the lower-power loads 116. In this embodiment, the voltage from the high-power storage device 104 is distributed via a DC-DC converter 106 to the lower-power loads 116 for such vehicle components.
[0019] In this embodiment, the DC-DC converter contains several voltage setpoints 108a, 108b, 108c, 108d in the vehicle. By increasing the number of voltage setpoints 108a, 108b, 108c, 108d in a vehicle, the electrical optimization system 100 optimizes the distribution of power to these lower-power components 116. According to the invention, the DC-DC converter 106 is connected to various low-power loads 116 in the vehicle, and the DC-DC converter 106 contains different voltage setpoints 108 for each component. Each voltage setpoint 108 is set to the optimal voltage for the component.
[0020] The DC-DC converter 106 includes a control unit 120 for supplying the individual loads with the most efficient voltage in the vehicle. In particular, it provides Fig. Figure 1B shows an expanded block diagram of the DC-DC converter 106. As in Fig. As shown in Figure 1B, the DC-DC converter 106 includes a controller 120 with at least one processor 122, which communicates with a main memory 124 that stores a set of instructions 126. The processor 122 is designed to communicate with the main memory 124, access the set of instructions 126, and execute the set of instructions 126 to cause the DC-DC converter to perform any of the procedures, processes, and features described herein.
[0021] The processor 122 can be any suitable processing device or set of processing devices, such as, but not limited to: a microprocessor, a microcontroller-based platform, a suitable integrated circuit, or one or more application-specific integrated circuits (ASICs). The main memory 124 can be any suitable storage device, such as, but not limited to: volatile memory (e.g., RAM, which may include non-volatile RAM, magnetic RAM, ferroelectric RAM, and any other suitable forms); non-volatile memory (e.g., disk memory, FLASH memory, EPROMs, EEPROMs, memristor-based non-volatile solid-state memory, etc.); immutable memory (e.g., EPROMs); or read-only memory.
[0022] In one embodiment, the processor 122 is configured to communicate with the memory 124, access the set of instructions 126, and execute the set of instructions 126 to cause the DC-DC converter to determine the individual loads and supply them with the most efficient voltage. In this embodiment, the memory 124 stores information regarding the optimal voltage for various components of the vehicle, and the memory 124 stores instructions 126 for controlling the power to each of the components to maximize efficiency and optimize power distribution.
[0023] As described above, the DC-DC converter 106 of the electricity optimization system 100 contains several voltage setpoints that supply individual loads of the vehicle. In this embodiment, the DC-DC converter 106 receives commands from a vehicle control system (such as the one in conjunction with Fig. 2. The vehicle control system 200 (described below) supplies power to various components in the vehicle. The DC-DC converter's control unit 120 registers the commands from the vehicle control system and provides power at the optimal voltage level for the appropriate vehicle system and / or component.
[0024] Referring again to Fig. The DC-DC converter 106 is also connected to the vehicle's high-energy storage device 110. The high-energy source 110 can be a capacitor or a battery in the vehicle. Thus, the DC-DC converter can draw power from either.
[0025] The DC-DC converter 106 also recharges the high-power storage device when required for operation. In particular, in certain embodiments, the high-power storage device 104 and the high-energy storage device 110 are designed to charge and / or discharge each other. Both the high-power storage device 104 and the high-energy storage device can be capacitors or batteries designed to charge, store power, discharge power, etc. However, in certain embodiments, the high-power storage device 104 is a more expensive, often larger device than the high-energy storage device 110. The high-power storage device 104 is not intended to hold and maintain a charge because this would be expensive and wasteful.Therefore, in certain embodiments, it is more cost-effective and efficient for the high-performance storage device 104 to receive power from the high-energy storage device 110 in order to charge the high-performance storage device 104 at a minimum operating load.
[0026] For example, when starting the vehicle, the engine draws power from the high-performance storage device 104. In this example, instead of the high-performance storage device 104 being fully charged before starting the vehicle, the high-energy storage device 110 charges the high-performance storage device 104 to provide the power needed to start the vehicle. For example, existing diesel truck starting systems contain two lead-acid batteries to provide sufficient power to start the truck. One of the batteries is used to charge the other battery to ensure that sufficient power is available to start the truck. After starting, this second battery is not used for any other purpose.Instead of using two batteries to start the truck, the electricity optimization system 100 provides the high-energy storage device 110, which charges the high-power storage device 104 with sufficient power to start the truck. In this example, after the vehicle has started, the high-power storage device 104 continues to supply other high-power loads.
[0027] In certain alternative embodiments, the high-energy storage device 110 does not charge the high-performance storage device 104; instead, the electricity optimization system 100 operates in reverse. Specifically, in certain embodiments, the high-performance storage device 104 charges the high-energy storage device for specific operations. One example is regenerative braking. In this example, the vehicle should recover as much energy as possible while decelerating. In this embodiment, the high-performance storage device 104 would recover as much energy as possible and then discharge the excess into the high-energy storage device 110, so that the high-performance storage device 104 can continue to charge and control the load from the braking system.
[0028] In certain embodiments, the high-performance storage device 104 can be a large capacitor, or a battery such as a lithium-ion battery or a lead-acid battery modified with thinner plates designed for its specific use. In certain embodiments, the high-energy storage device 110 can be a smaller capacitor, or a battery such as a lead-acid battery or a lithium-ion battery modified with thicker plates optimized for the energy storage device. Such a configuration offers more efficient power distribution and electricity management.
[0029] In various embodiments of the present disclosure, the DC-DC converter 106 of the electricity optimization system 100 also optimizes the electricity generation of a vehicle by monitoring and controlling the temperature of each component whose operation is affected by temperature. In particular, in this embodiment, the electricity generation optimization system 100 is further designed to control the temperature of the components in a vehicle by controlling a heater (not shown) and an air conditioner (not shown) of the vehicle. In this embodiment, the DC-DC converter 106 includes a temperature control module 130.
[0030] As in Fig. As shown in Figure 1B, the temperature control module 130 communicates with the controller 120 of the DC-DC converter 106. In this embodiment, the DC-DC converter 106 includes a controller 120 designed to switch on heaters and fans to control the temperature in the vehicle, the vehicle's batteries, capacitors, the engine, and other components, thereby improving vehicle operation by controlling the component temperature. Specifically, the temperature control module 130 includes one or more sensors 132 for monitoring the temperature of various components in the vehicle. The temperature control module 130 also includes a heat output 134 and an AC output 136.
[0031] In this embodiment, the electricity optimization system 100 uses the sensors 132 to detect the temperature of various components in the vehicle and to register the temperature information with the controller 120. In certain embodiments, the controller 120 causes the processor 122 to execute the multiple instructions 126 in memory 124 to reduce the temperature of the components in a vehicle by controlling an air conditioning system (not shown) in the vehicle. In certain embodiments, the controller 120 causes the processor 122 to execute the multiple instructions 126 in memory 124 to raise the temperature of certain components in the vehicle by controlling a heater (not shown) in the vehicle.
[0032] In another embodiment, the DC-DC converter 106 distributes power from the high-performance storage device 104 and the high-energy storage device 110 to control the temperature of the various vehicle components. In particular, in one embodiment, the control unit 120 of the DC-DC converter 106 causes the processor 122 to execute several instructions 126 stored in the memory 124 to calculate the energy available in the high-performance storage device 104 and the high-energy storage device 110. In this embodiment, the DC-DC converter can determine, at the end of each cycle, the power required to charge the high-performance storage device for the next cycle.The DC-DC converter 106 calculates the available energy from the two sources and uses some of it to start the engine, while the other energy is used to warm the vehicle, battery, or engine to improve vehicle performance. The heat from the DC-DC converter 106 and the generator 102 can be disseminated to the rest of the vehicle to cool the components within the DC-DC converter 106 and improve its operation.
[0033] Accordingly, through such a configuration, the electricity optimization system redistributes the heat generated during charging and / or starting the system to the various vehicle components in order to increase their performance.
[0034] It is understood that in certain embodiments, the system may be configured to include other energy generators, including hydraulic pumps, air compressors, water pumps, or systems that generate energy and store it in power loads within the vehicle or building. This applies particularly to the embodiments described above concerning the management of electrical energy generated by the generator. In certain alternative embodiments, a similar system incorporating an expensive high-capacity storage device, a cost-effective high-energy storage device, and a converter may be used to control and optimize other types of generation. In certain embodiments, the generator may also function as a motor to power the vehicle when required.
[0035] It is understood that the electricity optimization system of the present disclosure can also be used for electricity management in other devices that are not related to a vehicle and / or building electricity management.
[0036] Fig. Figure 2 presents an embodiment of a vehicle control system (VCS) 200 that may be included in a vehicle to perform the method 300 for operating the electricity optimization system 208 of the present disclosure. The VCS 200 includes various electronic control units (ECUs) responsible for monitoring and controlling the electrical systems or subsystems of the vehicle, as described in more detail below.

Other embodiments of the EOS 208 may include different, fewer, or additional components than those described below and in Figure 2. Fig. Included are the two shown.
[0037] As in Fig. As shown in Figure 2, the VCS 200 can include a data processor 202, which communicates with a memory 204 (also referred to here as a data storage device) and a vehicle data bus 206. The memory 204 stores a set of instructions. The processor 202 is designed to communicate with the memory 204, access the set of instructions, and execute the set of instructions to cause the electricity optimization system to execute one of the procedures, processes, and features described herein.
[0038] The processor 202 can be any suitable processing device or set of processing devices, such as, but not limited to: a microprocessor, a microcontroller-based platform, a suitable integrated circuit, or one or more application-specific integrated circuits (ASICs). The memory 204 can be any suitable memory device, such as, but not limited to: volatile memory (e.g., RAM, which may include non-volatile RAM, magnetic RAM, ferroelectric RAM, and any other suitable forms); non-volatile memory (e.g., disk memory, FLASH memory, EPROMs, EEPROMs, memristor-based non-volatile solid-state memory, etc.); immutable memory (e.g., EPROMs); or read-only memory.
[0039] In embodiments, the VCS 200 may include a general-purpose computer programmed with various programming instructions or modules stored in the data storage device 204 (e.g., electronic memory) or elsewhere. The VCS 200 further includes various electronic control units (ECUs) responsible for monitoring and controlling the vehicle's electrical systems or subsystems. Each ECU may, for example, include one or more inputs and outputs for collecting, receiving, and / or transmitting data, a memory for storing the data, and a processor for processing the data and / or generating new information based thereon.In the embodiment shown, the ECUs of the VCS 200 include an Electricity Optimization System (EOS) 208, a Telematics Control Unit (TCM) 210, a Body Control Module (BCM) 212, a Human-Machine Interface (HMI) 214, a Powertrain Control Module (PCM) 216 and various other ECUs 206.
[0040] The ECUs of the VCS 200 can be interconnected via the vehicle bus 206 (such as a Controller Area Network (CAN) bus), which carries data to and from the various ECUs as well as other vehicle and / or accessory components that communicate with the VCS 200. Furthermore, the data processor 202 can communicate with each of the ECUs and the data storage device 204 via the data bus 206 to perform one or more functions, including those related to the procedures described herein.
[0041] In this embodiment, the Electricity Optimization System (EOS) 208 is an ECU designed to control and monitor electrical power distributed to various vehicle components and to monitor and control the temperature of these various vehicle components. One embodiment of the EOS 208 is the one used in conjunction with Fig. System 100 described in Figure 1A. In this embodiment, the EOS 208 includes a processor 220 communicating with a memory 222 that stores several instructions 224, similar to the processor 202 and memory 204 of the vehicle control system 200 as described above.

[0042] In some embodiments, the EOS 208 is a separate, stand-alone ECU that is connected via the vehicle bus 206 to the BCM 212, the PCM 216, the TCU 210, and other vehicle ECUs to perform electrical optimization operations. Specifically, the EOS 208 converts a direct current (DC) source from a higher voltage level to a lower voltage level and distributes power to various components in the VCS 200. For example, the EOS 208 can receive commands from the VCS processor 202 to provide power to a specific component. The EOS 208 processes the commands to identify the appropriate ECU for executing the command and provides the appropriate power level to the appropriate component of the appropriate ECU.In other embodiments, the EOS 208 can comprise several segments integrated into various ECUs of the VCS 200, such as the BCM 212, the PCM 216, and / or the TCU 210, to process the EOS commands received by each ECU (for example, to supply specific components). In still other embodiments, the EOS 208 can be contained within a single ECU, such as the TCU 210, to supply components of the TCU 210.
[0043] The Body Control Module (BCM) 212 is an electronic control unit (ECU) for controlling and monitoring various electronic accessories within a vehicle's body.

The BCM 212 may also control other electronically driven components within the vehicle's body, such as air conditioning units, power mirrors, and power seats. In cases where the BCM 212 only controls and monitors the vehicle's doors, it may be referred to as the Door Control Unit (DCU), as will be evident.The BCM 212 can be designed to implement commands received from the FSO 208 relating to the doors, windows or other body components controlled by the BCM 212.
[0044] The Powertrain Control Module (PCM) 216 is an ECU for controlling and monitoring the vehicle's engine and transmission.

Similarly, when the TCU 210 receives a power engine start command, it sends the command to the PCM 216 via the vehicle bus 206. In some embodiments, the TCU 210 also receives internal data from other ECUs of the VCS 200 and / or the data processor 202 with instructions to send the internal data to the vehicle or another component of the characterization system of the remote keyless system (RKS) of this disclosure.
