Description

Technical Field

[0001] The invention relates to a vehicle control device and method for resting in a vehicle. Background Art

[0002] As the development of autonomous driving technology enables drivers to rest in the vehicle while driving, the focus has been on new technologies or information technology (IT) to provide an environment where drivers can rest in the vehicle while driving, but technology development through vehicle control has not been carried out.

[0003] Conventional vehicle control technologies are developed with a focus on improving fuel economy and / or driving performance. Furthermore, electronic device control technologies used to ensure the battery state of charge (SOC) are optimized only for specific conditions such as charging status.

[0004] This vehicle control technology can prevent occupants from resting in the vehicle when resting in the vehicle. For example, when sleeping in the vehicle, the noise and vibration caused by the engine repeatedly turning on and off can prevent occupants from sleeping.

[0009] (Patent Document 4) US20220073092 A1 Summary of the invention

[0010] The present invention provides a vehicle control device and method for controlling a vehicle so as to minimize factors that hinder passengers from resting in the vehicle.

[0011] In addition, the present invention provides a vehicle control device and method for controlling a vehicle so as to facilitate passengers' rest.

[0012] A vehicle control device according to an embodiment of the present invention may include a sensor for obtaining user information and a processor connected to the sensor, the processor being configured to: judge a user status based on the user information obtained by the sensor during driving, determine whether a rest mode entry condition is met based on the user status, and when it is determined that the rest mode entry condition is met, determine an in-vehicle rest mode based on user input received from a user interface, and execute vehicle control corresponding to the in-vehicle rest mode.

[0013] The processor may analyze the image captured by the camera to determine the user's fatigue level, and determine whether the user needs to rest based on the user's fatigue level.

[0014] The processor may analyze the brain wave signal measured by the brain wave sensor to determine the user's fatigue level, and determine whether the user needs to rest based on the user's fatigue level.

[0015] When entering the in-vehicle rest mode, the processor can identify and turn on the necessary controllers for optimizing the electronic equipment load, so that the remaining controllers among the controllers carried by the vehicle except the necessary controllers are turned off.

[0016] The in-vehicle rest mode can be divided into a driving rest mode and a parking rest mode based on the rest mode entry time point.

[0017] When the in-vehicle rest mode is determined to be the driving rest mode, the processor may lower the output voltage of the low-voltage DC converter to suppress power consumption of the high-voltage battery.

[0018] The processor may adjust upward an optimum SOC region determined in consideration of the efficiency of the high voltage battery, adjust downward a reference SOC serving as a reference for determining whether to perform idle charging, and restrict start of the engine for learning while the vehicle is running.

[0020] The processor may use the electric heating element for heating when the heater is running, limiting the use of the engine for heating.

[0021] When the in-vehicle rest mode is determined to be the post-parking rest mode, the processor may enter a preparation mode for entering the post-parking rest mode, and increase the output voltage of the low-voltage DC converter so as to charge the low-voltage battery with the high-voltage battery.

[0022] The processor may increase a reference SOC that is a reference for determining whether to perform idle charging, and when the high-voltage battery SOC is less than a target SOC, start the engine to charge the high-voltage battery.

[0024] The processor may terminate heating using the electric heating element, close an active air flap (AAF) to minimize cooling of the engine coolant, and increase a target coolant temperature to induce the engine to start when the heater is running.

[0025] The processor can determine whether the vehicle has arrived at a predetermined resting place. When it is determined that the vehicle has arrived at the predetermined resting place, it enters a post-parking rest mode, lowers the output voltage of the low-voltage DC converter, lowers the reference SOC that serves as a reference for determining whether to perform idle charging, and limits the start of the engine for learning while the vehicle is running.

[0026] The processor may limit activation of the heater and increase the indoor temperature of the vehicle even if the condenser temperature drops below a preset temperature when the air conditioner is in operation.

[0027] The processor can use the electric heating element to heat when the heater is running, close the active air flap to minimize the cooling of the engine coolant, and determine whether the indoor temperature of the vehicle is lower than a preset suitable resting temperature. When it is determined that the indoor temperature of the vehicle is lower than the preset suitable resting temperature, the engine is turned on for heating; if the indoor temperature of the vehicle reaches the preset suitable resting temperature, the engine is turned off.

[0035] The step of performing the vehicle control for rest during driving may include: when the air conditioner is operating, even if the condenser temperature drops below a preset temperature, the step of limiting activation of the heater; and the step of limiting a power variation amount of the air conditioner compressor.

[0036] The step of executing the vehicle control for rest during driving may include: a step of using an electric heating element for heating when the heater is running; and a step of using the engine for heating only during driving.

[0037] The step of executing vehicle control corresponding to the in-vehicle rest mode may include: when the in-vehicle rest mode is determined to be the rest mode after parking, the step of executing vehicle control for preparing to enter the rest mode after parking; the step of judging whether the vehicle has arrived at a rest place; when it is judged that the vehicle has arrived at the rest place, the step of executing vehicle control for resting after parking.

[0038] The step of executing vehicle control for preparing to enter the rest mode after parking may include: after entering the preparation mode for entering the rest mode after parking, increasing the output voltage of the low voltage DC converter to charge the low voltage battery with the high voltage battery.

[0047] When the in-vehicle rest mode is determined to be the post-parking rest mode, the processor can enter a preparation mode for entering the post-parking rest mode, increase the output voltage of the low-voltage DC converter so that the high-voltage battery can be used to charge the low-voltage battery, and increase the reference SOC used as a reference for determining whether to perform idle charging.

In assigning reference numerals to the components of each figure, it should be noted that the same reference numerals are attached to the same components as much as possible even if they are shown in different figures. In addition, in describing the embodiments of the present invention, if it is judged that the specific description of the relevant known structure or function will hinder the understanding of the embodiments of the present invention, its detailed description will be omitted.

[0062] In describing the components of the embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. Such terms are only used to distinguish the component from other components, and the nature, order, sequence, etc. of the corresponding components are not limited by the terms. In addition, unless clearly defined herein, all terms (including technical terms or scientific terms) used in this specification have the same meaning as generally understood by technicians in the technical field to which the present invention belongs. Terms that are the same as the contents of the generally used dictionary definitions should be interpreted as having a meaning consistent with the contextual meaning of the relevant technology, and should not be interpreted as having an idealized or formalized meaning unless clearly defined as having such a meaning in this specification.

[0063] Figure 1 It is a diagram showing the structure of a hybrid electric vehicle associated with the present invention.

[0064] A hybrid electric vehicle (HEV) may refer to a vehicle that uses two or more different driving sources. Generally speaking, a hybrid electric vehicle may use an engine that generates driving force by burning fuel (eg, gasoline) and a motor that generates driving force by using electric energy from a battery as driving sources.

[0065] Reference Figure 1 The hybrid electric vehicle may include an engine 10 , a hybrid starter generator (HSG) 20 , an engine clutch 30 , a motor 40 , a transmission 50 , and an inverter 60 .

[0066] The engine 10 can burn fuel to generate power (engine torque) required to drive the vehicle. Various well-known engines such as a gasoline engine or a diesel engine can be used as the engine 10. The engine 10 can control the output torque (ie, engine torque) according to the command of the engine management system (EMS).

[0067] The HSG 20 can be connected to the engine 10 via a belt. The HSG 20 can crank the engine 10 to start it. The HSG 20 can play a role in starting the engine when the electric vehicle mode is converted to the hybrid mode. When the engine 10 is started, the HSG 20 can also work as a generator that uses the power of the engine 10 to generate electrical energy. The electrical energy generated by the HSG 20 can be used to charge the battery B. The HSG 20 and the engine 10 can be collectively referred to as a power generation device (plant) G.

[0068] The engine clutch 30 may be disposed between the engine 10 and the motor 40 to disconnect / connect the power (output torque) of the engine 10. The engine clutch 30 may transmit or disconnect the power (engine torque) generated by the engine 10 to the drive wheels (wheels) by engaging or disengaging.

[0069] The motor 40 can receive power supply from the inverter 60 to generate power (motor power) and transmit it to the drive wheel. The motor 40 can change the rotation direction and speed (Revolution Per Minute: RPM) according to the instructions of the motor control unit (MCU) to control the output torque (motor torque) of the motor 40. The motor 40 can also generate back electromotive force when the remaining battery power (State of Charge: SOC) is insufficient or regenerative braking is performed to act as a generator to charge the battery B. Battery B can serve to supply the power required to drive the vehicle. In addition, battery B can be charged by the regenerative energy generated by the motor 40. A high-voltage battery (or a high-capacity battery) capable of outputting a preset high voltage (for example: above 400V) can be used as battery B.

[0070] The transmission 50 can transform the motor torque or the engine torque and the motor torque into a transmission ratio that matches the transmission gear (transmission gear) and output it. The transmission 50 can change the transmission gear according to the instruction of the transmission control unit (TCU). The TCU can determine the optimal transmission gear according to the vehicle's driving speed (i.e., vehicle speed or wheel speed), accelerator pedal position, engine speed and / or clutch travel through sensors in the vehicle.

[0071] The inverter 60 is a power converter configured between the motor 40 and the battery B, which can convert the power output from the battery B into motor driving power and supply it to the motor 40. For example, the inverter 60 can convert the DC voltage output from the battery B into the three-phase AC voltage required to drive the motor and supply it to the motor 40. The inverter 60 can adjust the power supplied to the motor 40 (for example, the output voltage) according to the instructions of the MCU to control the motor torque. In this embodiment, the case where the inverter 60 is configured between the motor 40 and the battery B is described as an example, but it is not limited to this. When the motor 40 used in the vehicle is a DC motor (direct current motor), a converter can also be configured between the motor 40 and the battery B, or the motor 40 and the battery B can be directly connected without using a power converter.

The sensor 110 may use the brain wave sensor 112 to measure (detect) the brain wave signal of the user. The brain wave sensor 112 may be composed of at least one electroencephalogram (EEG) sensor.

[0075] The sensor 110 may use temperature sensors 113 installed in the vehicle to measure the temperature of a specific location in the vehicle.

In addition, the sensor 110 may also use a temperature sensor installed on the engine coolant line to detect the engine coolant temperature (hereinafter referred to as coolant temperature).

[0076] The sensor 110 may also use a vehicle sensor to detect the driving state of the vehicle. The sensor 110 may use a wheel speed sensor 114 and a shift lever position sensor 115 to detect the driving speed and the shift lever position of the vehicle.

[0077] The sensor 110 may store the data (information) obtained by the camera 111, the brain wave sensor 112, the temperature sensor 113, the wheel speed sensor 114 and / or the shift lever position sensor 115 in the memory 130.

[0078] The user interface 120 can facilitate the interaction between the vehicle control device 100 and the user. The user interface 120 may include an input device (e.g., a keyboard, a touch pad, a microphone, and / or a touch screen, etc.) for generating data corresponding to the user operation and / or an output device (e.g., a display, a speaker, and / or a tactile signal output device, etc.) for outputting information corresponding to the operation of the vehicle control device 100.

[0079] The user interface 120 may include a hardware button and / or a software button having a function of selecting whether to enter the rest mode. If the user operates the corresponding button, the user interface 120 may output data (signals) corresponding to the corresponding button operation. For example, the user interface 120 may transmit data indicating entering the rest mode or ending the rest mode to the processor 150 according to the user's button operation.

[0080] The memory 130 may be a non-transitory storage medium that stores instructions executed by the processor 150.

[0081] The memory 130 may store an in-vehicle rest control algorithm, an image analysis algorithm, and / or an electroencephalogram analysis algorithm, etc. The memory 130 may store information (setting information) previously set by a system designer and / or a user. The memory 130 may store input data and / or output data of the processor 150.

[0082] The controller 140 may operate based on data (control instructions) transmitted from the processor 150. In addition, the controller 140 may obtain data (or information) requested by the processor 150 and transmit the obtained data to the processor 150. A plurality of controllers 140 may transmit and receive data to each other.

[0083] The controller 140 may include electronic control units (ECUs) and electrical devices (electronic equipment loads) installed in the vehicle, etc. The electronic control unit may include a hybrid control unit (HCU) 141, a motor control unit (MCU) 142, a battery management system (BMS) 143, a low voltage DC-DC converter (LDC) 144, an engine management system (EMS) 145, an air conditioning controller 146 and / or a body control module (BCM) 147, etc.

[0084] The HCU 141 can control the overall operation of the vehicle (eg, motor start, idle stop, engine stop during temporary braking, etc.) The MCU 142 can control the rotation direction and rotation speed of the motor 40, etc.

[0085] The BMS 143 may monitor the SOC, voltage, current, and / or temperature of the high-voltage battery and the low-voltage battery, etc. The BMS 143 may prevent the battery from being overcharged when the battery is charged and from being over-discharged when the battery is discharged, thereby managing the SOC of the battery.

[0086] The LDC 144 can convert the high voltage electricity supplied by the high voltage battery into low voltage electricity to charge the low voltage battery. The high voltage battery can supply the power required to drive the motor 40 of the vehicle. The low voltage battery can supply the power required for the operation of the electronic equipment load carried in the vehicle. The low voltage battery can use a 12V lithium battery or the like.

[0087] The EMS 145 is a system for controlling and managing the engine 10 , and can start (run) or stop (stop) the engine 10 . The EMS 145 can control the output torque of the engine 10 .

[0088] The air conditioning controller 146 may control the indoor temperature, humidity, air flow and / or air cleanliness of the vehicle, etc. The air conditioning controller 146 may compare the indoor temperature of the vehicle measured by the temperature sensor 113 with a preset set temperature, and control the operation of the air conditioner (refrigerator) or heater (heater) according to the comparison result.

[0089] The BCM 147 may control functions such as door locks, interior lighting, exterior lighting, wipers, turn indicators, and / or power management of the vehicle.

[0090] The electrical device may refer to an electronic device load that uses electrical energy in the vehicle, and may include a navigation terminal (Audio, Video, Navigation, AVN) 148, ambient light, and / or a vehicle dashboard, etc.

[0091] The processor 150 may control the overall operation of the vehicle control device 100. The processor 150 may be implemented by at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Programmable Logic Device (PLD), a Field Programmable Gate Arrays (FPGAs), a Central Processing Unit (CPU), a microcontroller, and a microprocessor.

[0092] The processor 150 can perform vehicle control according to a preset control logic so that the user riding in the vehicle can take a rest during driving or after parking. Resting can include reading, listening to the radio, listening to music and / or sleeping (or deep sleep), etc.

[0093] The processor 150 may sense (recognize) the state of the user riding in the vehicle (user state) using the camera 111 and / or the brain wave sensor 112 during the driving of the vehicle. The processor 150 may analyze the image captured by the camera 111 (e.g., facial feature analysis, etc.) to identify the user's fatigue. In addition, the processor 150 may analyze the brain wave signal measured by the brain wave sensor 112 to determine (recognize) the user's fatigue.

[0094] The processor 150 may determine whether the rest mode entry condition is satisfied based on the user state. The processor 150 may use the camera 111 and / or the brain wave sensor 112 installed in the vehicle to identify the state of the user (e.g., driver or passenger, etc.). The processor 150 may determine whether the user needs to rest based on the identified state of the user (user state). For example, when the fatigue of the user identified by the camera 111 and / or the brain wave sensor 112 exceeds a preset reference value, the processor 150 may determine that the user needs to rest. On the other hand, when the fatigue of the user identified by the camera 111 and / or the brain wave sensor 112 is below the preset reference value, the processor 150 may determine that the user does not need to rest. When the processor 150 determines that the user needs to rest, it may determine that the rest mode entry condition is satisfied (conforms). On the other hand, when the processor 150 determines that the user does not need to rest, it may determine that the rest mode entry condition is not satisfied.

[0095] When the processor 150 determines that the rest mode entry condition is satisfied, it may determine whether the user agrees to enter the rest mode. The processor 150 may output a message asking whether the user agrees to enter the rest mode through the user interface 120. If the inquiry message output through the user interface 120 is confirmed by the user and the user enters the consent or no, the processor 150 may receive data corresponding to the user input transmitted from the user interface 120. When the received data includes information indicating consent to enter the rest mode, the processor 150 may determine that the user agrees to enter the rest mode. When the received data includes information indicating disagreement to enter the rest mode, the processor 150 may determine that the user disagrees to enter the rest mode.

[0096] When it is determined that the rest mode entry condition is not met, the processor 150 may determine whether the user has chosen to enter the rest mode. The processor 150 may confirm whether data (control instructions) indicating the entry into the rest mode is received from the user interface 120. When it is determined that data indicating the entry into the rest mode is received from the user interface 120, the processor 150 may determine that the user has chosen to enter the rest mode. On the other hand, when it is determined that data indicating the entry into the rest mode is not received from the user interface 120, the processor 150 may determine that the user has not chosen to enter the rest mode.

[0097] When it is determined that the user agrees to enter the rest mode or that the user has selected to enter the rest mode, the processor 150 may determine to enter the in-vehicle rest mode based on the user input (or user selection). The in-vehicle rest mode may be divided into a driving rest mode and a parking rest mode based on the time point of entering the rest mode.

[0098] The processor 150 may perform vehicle control for resting while driving when it is determined that the vehicle enters the resting mode in the vehicle resting mode. The processor 150 may perform vehicle control such as electronic device load optimization control, engine start or stop control, and / or SOC control after entering the resting mode in the vehicle.

[0099] The processor 150 may perform vehicle control for resting while driving, and determine whether to end the rest mode. The processor 150 may perform vehicle control for resting while driving, and identify the user status using the camera 111 and / or the brain wave sensor 112, etc. The processor 150 may determine whether to end the rest mode based on the identified user status. For example, when the fatigue level of the user identified by the camera 111 and / or the brain wave sensor 112, etc. is below a preset reference value, the processor 150 may determine to end the rest mode. In addition, when a control instruction indicating to end the rest mode is received from the user interface 120, the processor 150 may determine to end the rest mode. When it is determined to end the rest mode, the processor 150 may end the vehicle control for resting while driving.

[0100] The processor 150 may recommend a possible parking place when determining to enter the after-parking rest mode in the in-vehicle rest mode. The processor 150 may search for a possible parking place that takes into account the current position and the driving path of the vehicle through the AVN 148, and recommend the searched possible parking place as a candidate rest place. The possible parking place may be a resting space such as a service area and / or a rest area where the vehicle can rest after parking.

[0101] The processor 150 may select any one of the recommended candidate resting places and set the selected candidate resting place as the resting place. For example, the processor 150 may determine the resting place that is closest to the current position of the vehicle among the resting spaces on the vehicle's driving path as the resting place. The processor 150 may use the AVN 148 to set the resting place selected by the user as the destination. In addition, the processor 150 may also set the resting place based on the user input received from the user interface 120.

[0102] The processor 150 may perform vehicle control for preparing to enter the rest mode after parking while the vehicle is traveling to the rest place as a destination. The processor 150 may perform vehicle control such as electronic equipment load optimization control, air conditioning control and / or SOC control after entering the preparation mode for entering the rest mode after parking.

[0103] The processor 150 may determine whether the vehicle has arrived at the resting place using the AVN 148. The AVN 148 may calculate the current position of the vehicle using a signal transmitted by a satellite. The AVN 148 may compare the calculated current position of the vehicle with the position of the resting place set as the destination to determine whether the vehicle has arrived at the resting place. The AVN 148 may transmit the result of determining whether the vehicle has arrived at the resting place to the processor 150. The processor 150 may determine whether the vehicle has arrived at the resting place based on the determination result transmitted from the AVN 148.

[0104] When the processor 150 determines that the vehicle has arrived at the resting place, it can determine whether the vehicle is in a parked state. The processor 150 can determine whether the vehicle is parked based on the vehicle speed and / or the position of the shift lever. For example, when the vehicle speed is 0 km / h, that is, it is stationary and the shift lever position is P gear, the processor 150 can determine that the vehicle is in a parked state. In addition, the processor 150 can use the camera 111 to obtain the surrounding image of the vehicle, and use the obtained image to determine whether the vehicle is parked in the parking area. When the vehicle is parked in the parking area, the processor 150 can determine that the vehicle is in a parked state.

[0105] When it is determined that the vehicle is in a parking state, the processor 150 may enter a parking rest mode and perform vehicle control for rest. After entering the parking rest mode, the processor 150 may perform vehicle control such as electronic equipment load optimization control, SOC control and / or engine start and stop optimization control.

[0106] The processor 150 may perform vehicle control for rest after parking and determine whether to end the rest mode. The processor 150 may determine the user state by analyzing the images obtained by the camera 111 and / or the brain wave sensor 112 and / or the brain wave analysis. The processor 150 may determine whether to end the rest mode based on the determined user state. For example, when the user state is converted from a sleeping state to a wake-up state, the processor 150 may determine to end the rest. After determining to end the rest, the processor 150 may end the vehicle control for rest after parking.

[0107] The following describes in detail the vehicle control method after entering the in-vehicle rest mode.

[0108] First, the vehicle control when entering the rest mode while driving is described. When entering the rest mode while driving, the processor 150 can perform electronic equipment load optimization control. Specifically, the processor 150 can identify the necessary controllers in order to optimize the electronic equipment load, and turn off (stop) the remaining controllers of the controller 140 carried in the vehicle except for the identified necessary controllers. The necessary controllers are controllers required to provide a rest environment while driving, which can be predetermined by the system designer. For example, the processor 150 can identify controllers such as HCU 141, MCU 142, BMS 143, LDC 144, EMS 145, air conditioning controller 146, BCM 147 and AVN 148 as necessary controllers for rest while driving, and only turn on (run) the identified necessary controllers, and turn off (stop) unnecessary electrical devices (electronic devices) such as the car dashboard except the necessary controllers. In this embodiment, it is described that the necessary controllers corresponding to the in-vehicle rest mode are predetermined by the system designer, but it can also be implemented as follows: the processor 150 directly identifies the necessary controllers in the controller 140 according to the identification criteria predetermined by the system designer.

[0109] In addition, the processor 150 may lower the output voltage of the LDC 144 to optimize the electronic device load. The processor 150 may transmit an instruction indicating low power operation to the LDC 144. The LDC may operate at a low power level that can maintain the low voltage battery state at a preset level according to the instructions of the processor 150, and perform SOC protection control of the high voltage battery. When the voltage of the low voltage battery is at a normal level (usually above 12.1V), the LDC 144 may perform SOC protection control and avoid using the high voltage battery as much as possible.

[0110] The processor 150 may perform engine on and off optimization control after entering the driving rest mode. Specifically, the processor 150 may use the heater hybrid control to the minimum extent to suppress engine on when the air conditioner is running after entering the driving rest mode. The heater hybrid control may be defined as starting and controlling the heater when the condenser temperature drops below a preset temperature when the air conditioner is running.

[0111] The processor 150 may limit the power variation of the air conditioner compressor. The processor 150 may limit the power variation of the air conditioner compressor to a preset limit value to reduce the air conditioner load. For example, the processor 150 may limit the power variation (or power variation) of the air conditioner compressor to 10W / 100ms. By limiting the power variation of the air conditioner compressor in this way, the power consumption of the high-voltage battery (or the power consumption of the air conditioner) may be minimized.

[0112] In addition, after entering the rest mode during driving, when the heater is running, even if the indoor temperature of the vehicle cannot reach the set temperature, the processor 150 may not start the engine 10, but use the electric heating element to adjust the indoor temperature of the vehicle. The electric heating element may use a positive temperature coefficient (PTC) heater or the like. In addition, during parking, even if the coolant temperature drops below a preset reference liquid temperature, the processor 150 may suppress the engine from starting, and may start the engine 10 during driving to ensure a heat source.

[0113] In addition, after entering the rest mode during driving, the processor 150 may prohibit the engine from being turned on for learning. The processor 150 may limit the engine operation for engine learning and / or engine clutch learning, etc., which is implemented when the vehicle is parked or electric vehicle (EV) is driving. The processor 150 may limit learning in the rest mode during driving and perform learning in the next drive cycle. In the rest mode during driving, the control of turning on the engine 10 for learning while parking is prohibited, so that the vehicle vibration and noise caused by turning on the engine can be suppressed in the parked state.

[0114] The processor 150 may perform SOC control after entering the rest mode during driving. Specifically, the processor 150 may lower the reference SOC for determining whether to charge at idle speed, thereby minimizing the number of times the engine 10 is turned on due to idling.

[0115] In addition, the processor 150 can limit the power variation (variation) of the air conditioning compressor to a preset limit value (eg, 10W / 100ms). By reducing the power variation of the air conditioning compressor, the processor 150 can minimize the power consumption of the high-voltage battery caused by the air conditioning.

[0116] In addition, the processor 150 may adjust the optimal SOC region (range) upward to prevent the engine 10 from starting (starting) when the vehicle is parked or traveling at a low speed. The optimal SOC region may be defined as a region where the high-voltage battery can perform at its best efficiency. By adjusting the optimal SOC region of the high-voltage battery upward, the engine 10 may be prevented from starting even if the power of the high-voltage battery is consumed.

[0117] Next, vehicle control when entering a preparation mode for entering a rest mode after parking will be described.

[0118] The processor 150 can identify the necessary controllers for maintaining the preparation mode for entering the rest mode after parking. In other words, the processor 150 can identify the necessary controllers that must be provided in order to maintain the preparation mode (preparation environment) for entering the rest mode after parking.

[0119] The processor 150 may only enable (operate) the identified necessary controllers, and shut down (or stop) the remaining controllers that are not identified as necessary controllers among the controllers 140 installed in the vehicle. For example, the processor 150 may shut down unnecessary electrical devices (electronic equipment loads), such as a car dashboard, a head-up display (HUD), and / or interior lighting, except for the necessary controllers such as the HCU 141, MCU 142, BMS 143, LDC 144, EMS 145, air conditioning controller 146, BCM 147, and AVN 148.

[0120] The processor 150 may increase the output voltage of the LDC 144. According to the instruction of the processor 150, the LDC 144 may operate at a high power to maintain the SOC of the low voltage battery above a preset reference level when the vehicle is parked, so as to charge the low voltage battery to the maximum extent.

[0121] The processor 150 can lower the target temperature when the air conditioner is running (in use). At this time, the processor 150 can adjust the target temperature of the air conditioner to be lower than the temperature set by the user. In this way, the interior of the vehicle is sufficiently cooled so that the user does not feel hot when resting (for example, sleeping), thereby minimizing the use of the air conditioner after parking, thereby ensuring the SOC of the high-voltage battery.

[0122] The processor 150 can terminate the use of the electric heating element for heating when the heater is running. In other words, the processor 150 can minimize the use of the PTC heater, thereby minimizing the power consumption of the electronic equipment load.

[0123] The processor 150 may increase the target coolant temperature to induce the engine to start. This is because if the coolant temperature drops, the engine 10 needs to be started to increase the coolant temperature, but when the engine 10 is turned on during rest (e.g., sleeping), it will hinder the user's rest. Therefore, in order to fully ensure the coolant temperature before parking, the target coolant temperature may be increased to induce the engine to start.

[0124] The processor 150 may close an active air flap (AAF) to minimize cooling of the coolant. The AAF is a device for managing heat in the engine compartment. If the coolant temperature rises, it opens to improve the cooling efficiency of the coolant by drawing in air. If the coolant temperature drops, it closes to reduce air resistance and improve fuel efficiency and / or power consumption efficiency.

[0125] The processor 150 can increase the idle charging reference SOC (SOC IDLE The processor 150 increases the reference SOC (SOC IDLE) to induce the engine to start, thereby minimizing the reduction of the high-voltage battery SOC. Idle charging can be defined as a mode in which, when the high-voltage battery SOC is less than a reference SOC, the engine is started to charge the high-voltage battery in order to maintain the high-voltage battery SOC above the reference SOC.

[0126] The processor 150 may perform target SOC control. When the battery SOC does not reach the target SOC through the target SOC control, the processor 150 may induce the engine to start to charge the battery through the low SOC region control. The low SOC region control may be defined as when the battery is discharged in the case where the battery SOC is in the low region L, the engine 10 is actively intervened to bring the battery SOC to the optimal SOC region.

[0127] In the above-mentioned preparation mode for entering the rest mode after parking, the vehicle control can increase the SOC of the high-voltage battery and the low-voltage battery during driving to the rest place, and perform air conditioning control to create a comfortable rest environment, so that the best rest state can be maintained when entering the rest mode after parking.

[0128] Next, vehicle control when entering the rest mode after parking will be described.

[0129] The processor 150 can identify the necessary controllers that are necessary to maintain the environment (or the rest environment after parking) in the rest mode after parking. The processor 150 can only turn on (run) the identified necessary controllers. The processor 150 can turn off (or stop) the remaining controllers that are not identified as necessary controllers among the controllers installed in the vehicle. For example, the processor 150 can turn off unnecessary electrical devices, such as the car dashboard, AVN 148, and indoor lighting (ambient light) except for the necessary controllers such as HCU 141, MCU 142, BMS 143, LDC 144, EMS 145, air conditioning controller 146, and BCM 147.

[0130] The processor 150 may lower the output voltage of the LDC 144. The LDC 144 may perform SOC protection control of the high voltage battery at a low power operation that can maintain the low voltage battery state at a preset level according to the instruction of the processor 150. The LDC 144 may perform SOC protection control that minimizes the use of the high voltage battery when the voltage of the low voltage battery is at a normal level (usually above 12.1V).

[0131] The processor 150 can lower the idle charging reference SOC (SOC IDLE The processor 150 may lower the reference SOC (SOC IDLE ), minimizing the engine starting due to idling.

[0132] The processor 150 may prohibit starting the engine for learning. The processor 150 may limit the operation of the engine for engine learning and / or engine clutch learning, etc., which is implemented when the vehicle is parked or EV driving. The processor 150 may limit learning in the rest mode during driving, and then perform learning in the next drive cycle. In the rest mode during driving, starting the engine for learning while parked is prohibited, so that vehicle vibration and noise caused by starting the engine in the parked state can be suppressed.

[0133] The processor 150 may not use the heater hybrid control when the air conditioner is operating. The heater hybrid control means that when the condenser temperature drops below a preset temperature while the air conditioner is operating, the heater is activated for control. The processor 150 may control the air conditioner controller 146 in the driving rest mode so that even if the air conditioner is operating and the condenser temperature drops below a preset temperature, the heater hybrid control is minimized to suppress the engine from starting. This is because the user perceives temperature changes more slowly in a resting state (e.g., sleeping state), and thus the necessity for performing rapid temperature control is less.

[0134] To account for the drop in body temperature during rest, processor 150 may adjust the interior temperature of the vehicle upward.

[0135] The processor 150 may use an electric heating element to adjust the interior temperature of the vehicle when the heater is running. Even if the interior temperature of the vehicle is lower than the set temperature, the processor 150 uses an electric heating element such as a positive temperature coefficient (PTC) heater to provide heating as much as possible. In addition, when the vehicle is parked, the processor 150 may suppress the engine from starting even if the coolant temperature drops, and when driving, the processor 150 may ensure the heat source by starting the engine. The processor 150 may close the Active Air Flap (AAF) to minimize the cooling of the coolant.

[0136] The processor 150 may determine whether the current indoor temperature is lower than the preset resting suitable temperature. The processor 150 may use the temperature sensor 113 to measure the current indoor temperature of the vehicle, and compare the measured current indoor temperature with the resting suitable temperature. When it is determined that the current indoor temperature is lower than the preset resting suitable temperature, the processor 150 may execute the engine start control. When the current indoor temperature is lower than the preset resting suitable temperature, the processor 150 may start the engine 10 to provide heating to the interior of the vehicle.

[0137] The processor 150 may determine whether the current temperature in the vehicle has reached the resting suitable temperature. The processor 150 may compare the current temperature in the vehicle with the "resting suitable temperature + α". When the comparison result is that the current indoor temperature is consistent with the "resting suitable temperature + α", it may be determined that the current indoor temperature has reached the resting suitable temperature. The tolerance range may be determined to be within 10% of the resting suitable temperature due to hysteresis. When it is determined that the current temperature in the vehicle has reached the resting suitable temperature, the processor 150 may perform engine shut-down control. That is, the processor 150 may shut down the engine 10 when the current temperature in the vehicle reaches the resting suitable temperature.

[0138] In the above-mentioned rest mode after parking, vehicle control is designed to minimize factors that prevent passengers from resting through optimal control for rest, and control the vehicle in the best state so that passengers can rest, which can prevent air conditioning control and engine from starting.

[0139] Figure 3a FIG. 1 is a diagram for describing the battery SOC control during normal driving associated with the present invention. Figure 3b : is a diagram for describing the battery SOC control in the rest mode during driving according to an embodiment of the present invention, Figure 3c FIG. 4 is a diagram for describing battery SOC control in a preparation mode for entering a rest mode after parking according to an embodiment of the present invention.

[0140] Reference Figure 3a to Figure 3c , the battery SOC area can be divided into a very high area (Critical High: CH), a high area (High: H), a normal area (normal: N), a low area (Low: L) and a very low area (Critical Low: CL). The optimal SOC area is predetermined by the system designer and can be a protected area that makes the vehicle efficient and prevents the battery SOC from entering the low area (L).

[0141] Reference Figure 3a During normal driving, the BMS 143 can limit the battery charging power when the battery SOC is in a very high region CH. In other words, the BMS 143 can limit the battery charging when the battery SOC belongs to a very high region CH. The BMS 143 can limit the battery discharging power, i.e., the battery discharging, when the battery SOC is in a very low region CL.

[0142] BMS143 does not limit the battery charging power and battery discharging power when the battery SOC is in the high area H, the normal area N, or the low area L. BMS143 can make the vehicle run in EV mode to consume battery power when the battery SOC is in the high area H. BMS143 can start the engine 10 to charge the battery (high-voltage battery) when the battery SOC is in the low area L. BMS143 can perform battery operation based on a preset battery operation strategy so that the battery SOC is in the optimal SOC area (for example: 60-65%).

[0143] Reference Figure 3b When BMS143 enters the rest mode during driving, it can lower the idle charging reference SOC (SOC IDLE ). With the idle charging reference SOC (SOC IDLE ) can minimize the engine starting due to idling.

[0144] In addition, BMS143 can adjust the optimal SOC area higher than that during normal driving, thereby suppressing (limiting) starting the engine 10 during parking or low-speed driving. At this time, BMS143 can adjust the optimal SOC area to a preset range. With the increase in the optimal SOC area, the engine can be suppressed from starting even if the battery power is consumed. In addition, BMS143 can perform battery operation by reducing the hysteresis of the battery, so that the battery SOC is maintained at a high SOC as much as possible, while maintaining the battery SOC in the SOC area considering the battery efficiency.

[0145] Reference Figure 3c When BMS143 enters the preparation mode for entering the rest mode after parking, it can increase the idle charging reference SOC (SOC IDLE By increasing the idle charging reference SOC (SOC IDLE ), the engine can be induced to start to minimize battery discharge. In addition, when the battery SOC does not reach the target SOC through the target SOC control, the BMS 143 can induce the engine to start to charge the battery through the low SOC area control. The low SOC area control can be defined as when the battery is discharged in the case where the battery SOC is in the low area L, the engine 10 is actively intervened to make the battery SOC reach the optimal SOC area.

[0146] Figure 4 FIG. 4 is a flow chart showing a vehicle control method according to an embodiment of the present invention.

[0147] The processor 150 of the vehicle control device 100 may determine whether the rest mode entry condition is satisfied based on the user state during driving (S100). The processor 150 may use the camera 111 and / or the brain wave sensor 112 installed in the vehicle to identify the state of the user (e.g., the driver or the passenger, etc.). The processor 150 may determine whether the user needs to rest based on the identified user state. For example, when the fatigue of the user identified by the camera 111 and / or the brain wave sensor 112 exceeds a preset reference value, the processor 150 may determine that the user needs to rest. On the other hand, when the fatigue of the user identified by the camera 111 and / or the brain wave sensor 112 is below the preset reference value, the processor 150 may determine that the user does not need to rest. When the processor 150 determines that the user needs to rest, it may determine that the rest mode entry condition is satisfied. On the other hand, when the processor 150 determines that the user does not need to rest, it may determine that the rest mode entry condition is not satisfied.

[0148] When the processor 150 determines that the rest mode entry condition is met, it can determine whether the user agrees to enter the rest mode (S110). The processor 150 can output information asking whether to agree to enter the rest mode through the user interface 120. If the user enters the consent or no after confirming the inquiry information output through the user interface 120, the processor 150 can receive data corresponding to the user input transmitted from the user interface 120. When the received data includes information indicating consent to enter the rest mode, the processor 150 can determine that the user agrees to enter the rest mode. When the received data includes information indicating disagreement to enter the rest mode, the processor 150 can determine that the user disagrees to enter the rest mode.

[0149] When the processor 150 determines that the rest mode entry condition is not satisfied, it may determine whether the user has chosen to enter the rest mode (S120). The processor 150 may confirm whether a control instruction (or data) indicating entry into the rest mode is received from the user interface 120. When the processor 150 confirms that a control instruction indicating entry into the rest mode is received from the user interface 120, it may determine that the user has chosen to enter the rest mode. On the other hand, when the processor 150 confirms that a control instruction indicating entry into the rest mode is not received from the user interface 120, it may determine that the user has not chosen to enter the rest mode.

[0150] When it is determined in S110 that the user does not agree to enter the rest mode, or when it is determined in S120 that the user does not choose to enter the rest mode, the processor 150 may return to S100.

[0151] When it is determined in S110 that the user agrees to enter the rest mode, or when it is determined in S120 that the user has selected to enter the rest mode, the processor 150 may determine whether to enter the driving rest mode based on the user input (or user selection) (S130). The processor 150 may determine whether to enter the driving rest mode according to the user's selection of the in-vehicle rest mode received from the user interface 120. The in-vehicle rest mode can be divided into a driving rest mode and a parking rest mode.

[0152] The processor 150 may perform vehicle control for resting while driving (S140) when determining to enter the resting mode while driving. The processor 150 may perform vehicle control such as electronic device load optimization control, engine start or stop control and / or SOC control after entering the resting mode while driving.

[0153] The processor 150 may perform vehicle control for resting while driving, and determine whether to end the rest mode (S150). The processor 150 may perform vehicle control for resting while driving, and use the camera 111 and / or the brain wave sensor 112 to identify the user status. The processor 150 may determine whether to end the rest mode based on the identified user status. For example, the processor 150 may determine to end the rest mode when the fatigue level of the user identified by the camera 111 and / or the brain wave sensor 112 is below a preset reference value. In addition, the processor 150 may determine to end the rest mode when receiving a control instruction indicating to end the rest mode from the user interface 120. The processor 150 may end the vehicle control for resting in the vehicle when determining to end the rest mode.

[0154] When it is not determined in S130 to enter the rest mode during driving, the processor 150 may perform vehicle control for preparing to enter the rest mode after parking (S160). In other words, when it is determined in S130 to enter the rest mode after parking in the in-vehicle rest mode according to the user input received from the user interface 120, the processor 150 may perform vehicle control for preparing to enter the rest mode after parking. The processor 150 may perform vehicle control such as electronic equipment load optimization control, air conditioning control and / or SOC control after entering the preparation mode for entering the rest mode after parking.

[0155] The processor 150 may determine whether the vehicle has arrived at the resting place (S170). The processor 150 may use the AVN 148 to determine whether the vehicle has arrived at the resting place. The AVN 148 may calculate the current position of the vehicle using a signal transmitted from a satellite. The AVN 148 may compare the calculated current position of the vehicle with the position of the resting place set as the destination to determine whether the vehicle has arrived at the resting place. The AVN 148 may transmit the result of determining whether the vehicle has arrived at the resting place to the processor 150. The processor 150 may determine whether the vehicle has arrived at the resting place based on the determination result transmitted from the AVN 148. The resting place, as a place where the vehicle can be parked, may be a resting space where the vehicle can rest after parking, such as a service area and / or a rest area.

[0156] When the processor 150 determines that the vehicle has arrived at the resting place, it can perform vehicle control for resting after parking (S180). After entering the resting mode after parking, the processor 150 can perform vehicle control such as electronic equipment load optimization control, SOC control and / or engine start and stop optimization control.

[0157] The processor 150 may perform vehicle control for rest after parking and determine whether to end the rest mode (S190). The processor 150 may determine the user state by analyzing the images obtained by the camera 111 and / or the brain wave sensor 112 and / or the brain wave analysis. The processor 150 may determine whether to end the rest mode based on the determined user state. As an example, when the user state is converted from a sleeping state to a waking state, the processor 150 may determine to end the rest mode. After determining to end the rest mode, the processor 150 may end the vehicle control for rest after parking.

[0158] Figure 5 The flowchart is a diagram showing a vehicle control method for resting while driving according to an embodiment of the present invention.

[0159] The processor 150 may identify the necessary controllers for maintaining the driving rest mode (S200). The necessary controllers may be controllers that are necessary to maintain the environment (or driving rest environment) in the driving rest mode.

[0160] The processor 150 may only enable (operate) the identified necessary controllers (S210). The processor 150 may enable the remaining controllers in the controllers 140 mounted in the vehicle that are not identified as necessary controllers to be turned off (or stopped). For example, the processor 150 may enable unnecessary electronic equipment loads to be turned off, such as a car dashboard except for necessary controllers such as the HCU 141, MCU 142, BMS 143, LDC 144, EMS 145, air conditioning controller 146, BCM 147, and AVN 148.

[0161] The processor 150 may lower the LDC voltage (i.e., the output voltage of the LDC 144) (S220). The LDC may perform high-voltage battery SOC protection control at a low power level that can maintain the current state of the low-voltage battery according to the instruction of the processor 150. In other words, the LDC 144 may perform control that minimizes the use of the high-voltage battery when the low-voltage battery voltage is at a normal level (usually above 12.1V).

[0162] The processor 150 may adjust the optimal SOC upward (S230). The processor 150 may adjust the optimal SOC region upward to prevent the engine 10 from turning on (starting) when the vehicle is parked or traveling at a low speed. Since the optimal SOC region of the high-voltage battery is adjusted upward, the engine 10 may be inhibited from turning on even if the high-voltage battery power is consumed.

[0163] The processor 150 may lower the idle charge reference SOC (S240). The processor 150 may lower the reference SOC, which is a reference for determining whether to perform idle charge, to minimize the engine being turned on due to idling.

[0164] The processor 150 may prohibit the start of the engine for learning while the vehicle is running (S250). The processor 150 may limit the operation of the engine for engine learning and / or engine clutch learning, etc., which is implemented when the vehicle is temporarily parked or in pure electric (EV) driving. The processor 150 may limit learning in the rest mode during driving and perform learning in the next drive cycle. In the rest mode during driving, the control of starting the engine 10 for learning while the vehicle is parked is prohibited, thereby suppressing the vehicle vibration and noise caused by the engine being turned on in the parked state.

[0165] The processor 150 may determine whether the air conditioner (refrigerator) is running ( S260 ). The processor 150 may confirm whether the air conditioner is running by communicating with the air conditioner controller 146 .

[0166] When the processor 150 determines that the air conditioner is in operation, the heater hybrid control may not be used (S270). The heater hybrid control means that when the air conditioner is in operation, the heater is activated for control when the condenser temperature drops below a preset temperature. The processor 150 may control the air conditioner controller 146 in the driving rest mode so that even when the air conditioner is in operation and the condenser temperature drops below a preset temperature, the heater hybrid control is minimized to suppress the engine from starting.

[0167] The processor 150 may limit the power variation of the air-conditioning compressor (S280). The processor 150 may limit the power variation of the air-conditioning compressor to a preset limit value to reduce the air-conditioning load. For example, the processor 150 may limit the power variation (or power variation) of the air-conditioning compressor to 10W / 100ms. By limiting the power variation of the air-conditioning compressor in this way, the power consumption of the high-voltage battery (or the power consumption of the air-conditioning) may be minimized.

[0168] When the processor 150 determines that the air conditioner is not running, it can determine whether the heater (blower heater) is running ( S290 ). The processor 150 can confirm whether the heater is running by communicating with the air conditioner controller 146 .

[0169] When the processor 150 determines that the heater is in operation, the electric heating element S300 may be used. Even if the indoor temperature of the vehicle is lower than the set temperature, the processor 150 uses the electric heating element such as the PTC heater as much as possible to adjust the indoor temperature of the vehicle. In addition, when the vehicle is parked, even if the coolant temperature drops below the preset reference temperature, the processor 150 may suppress the engine from starting, and start the engine 10 to ensure the heat source during driving.

[0170] The processor 150 may perform the engine ON control during driving (S310). The processor 150 may control the EMS 145 so that the engine ON control is performed during driving.

[0171] Figure 6 The flowchart is a diagram showing a vehicle control method for preparing to enter a rest mode after parking according to an embodiment of the present invention.

[0172] The processor 150 may identify a necessary controller for maintaining a preparation mode for entering a rest mode after parking (S400). The necessary controller may be a controller that is necessary for maintaining the preparation mode (preparation environment) for entering a rest mode after parking.

[0173] The processor 150 may only enable (operate) the identified necessary controllers (S410). The processor 150 may shut down (or stop) the remaining controllers in the controllers 140 mounted in the vehicle that are not identified as necessary controllers. For example, the processor 150 may shut down unnecessary electronic equipment loads, such as the car dashboard, HUD, and interior lighting, except for the necessary controllers such as the HCU 141, MCU 142, BMS 143, LDC 144, EMS 145, air conditioning controller 146, BCM 147, and AVN 148.

[0174] The processor 150 may increase the LDC voltage (ie, the output voltage of the LDC 144) (S420). According to the instruction of the processor 150, the LDC 144 may operate at high power to maintain the low voltage battery SOC above a preset reference level during parking, thereby charging the low voltage battery to the maximum extent.

[0175] The processor 150 may increase the idle charge reference SOC (S430). The processor 150 increases the reference SOC, which is a reference for determining whether to perform idle charging, to induce the engine to start, thereby minimizing the reduction of the high-voltage battery SOC. Idle charging may be defined as a mode in which the engine is started to charge the high-voltage battery in order to maintain the high-voltage battery SOC above the reference SOC when the high-voltage battery SOC is less than the reference SOC.

[0176] The processor 150 may perform target SOC control (S440). When the battery SOC does not reach the target SOC through the target SOC control, the processor 150 may induce the engine to start to charge the battery through the low SOC region control. The low SOC region control may be defined as when the battery is discharged in the case where the battery SOC is in the low region L, the engine 10 is actively intervened to bring the battery SOC to the optimal SOC region.

[0177] The processor 150 may determine whether the air conditioner is running ( S450 ). The processor 150 may confirm whether the air conditioner is running by communicating with the air conditioner controller 146 .

[0178] When the processor 150 determines that the air conditioner is running, it can lower the target temperature (S460). At this time, the processor 150 can adjust the target temperature of the air conditioner to be lower than the temperature set by the user. In this way, the interior of the vehicle is sufficiently cooled so that the user does not feel hot when resting (for example, sleeping), thereby minimizing the use of the air conditioner after parking, thereby ensuring the SOC of the high-voltage battery.

[0179] When the processor 150 determines that the air conditioner is not running, it can determine whether the heater is running ( S470 ). The processor 150 can confirm whether the heater is running by communicating with the air conditioner controller 146 .

[0180] When the processor 150 determines that the heater is operating, the electric heating element may not be used (S480). The processor 150 may terminate the use of the electric heating element for heating when the heater is operating. In other words, the processor 150 may minimize the use of the PTC heater to minimize the power consumption of the electronic device load.

[0181] The processor 150 may perform control to close an active air flap (AAF) to minimize cooling of the coolant (S490). The AAF is a device for managing heat in the engine compartment. If the coolant temperature rises, it is opened to improve the cooling efficiency of the coolant by sucking in air. If the coolant temperature drops, it is closed to reduce air resistance and improve fuel efficiency and / or power consumption efficiency.

[0182] The processor 150 may increase the target coolant temperature to induce the engine to start (S500). This is because if the coolant temperature drops, the engine 10 needs to be started to increase the coolant temperature, but when the engine 10 is turned on during rest (e.g., sleeping), it will hinder the user's rest. Therefore, in order to fully ensure the coolant temperature before parking, the target coolant temperature may be increased to induce the engine to start.

[0183] According to the above embodiment, the vehicle control for preparing to enter the rest mode after parking can increase the SOC of the high-voltage battery and the low-voltage battery during driving to the rest place, and perform air conditioning control to create a comfortable rest environment, so that the best rest state can be maintained when entering the rest mode after parking.

[0184] Figure 7 The flowchart is a diagram showing a vehicle control method for resting after parking according to an embodiment of the present invention.

[0185] The processor 150 may identify the necessary controllers for maintaining the rest mode after parking (S600). The necessary controllers may be controllers that are necessary to maintain the environment (or rest environment after parking) in the rest mode after parking.

[0186] The processor 150 may only enable (operate) the identified necessary controllers (S610). The processor 150 may enable the remaining controllers in the vehicle that are not identified as necessary controllers to be turned off (or stopped). For example, the processor 150 may turn off unnecessary electrical devices, such as the car dashboard, AVN 148, and interior lighting, except for the necessary controllers such as the HCU 141, MCU 142, BMS 143, LDC 144, EMS 145, air conditioning controller 146, and BCM 147.

[0187] The processor 150 may lower the output voltage of the LDC 144 (S620). The LDC 144 may perform SOC protection control of the high voltage battery at a low power level that can maintain the current state of the low voltage battery according to the instruction of the processor 150. In other words, the LDC 144 may perform control to minimize the use of the high voltage battery when the voltage of the low voltage battery is at a normal level (usually above 12.1V).

[0188] The processor 150 may lower the idle charging reference SOC (S630). The processor 150 may lower the reference SOC, which is the reference for determining whether to perform idle charging, to minimize the engine starting due to idling. Idle charging may be defined as a mode in which the engine is started to charge the high-voltage battery in order to maintain the high-voltage battery SOC above the reference SOC when the high-voltage battery SOC is less than the reference SOC.

[0189] The processor 150 may prohibit starting the engine for learning (S640). The processor 150 may limit the operation of the engine for engine learning and / or engine clutch learning, etc., which is implemented when the vehicle is parked or EV is driving. The processor 150 may limit the learning in the rest mode during driving and perform the learning in the next drive cycle. In the rest mode during driving, starting the engine for learning during parking is prohibited, so that the vehicle vibration and noise caused by starting the engine in the parking state can be suppressed.

[0190] The processor 150 may determine whether the air conditioner is running (S650). The processor 150 may confirm whether the air conditioner is running by communicating with the air conditioner controller 146.

[0191] When the processor 150 determines that the air conditioner is in operation, the heater hybrid control (S660) may not be used. The heater hybrid control means that when the air conditioner is in operation, the heater is activated for control when the condenser temperature drops below a preset temperature. The processor 150 may control the air conditioner controller 146 in the rest mode during driving, so that even when the air conditioner is in operation and the condenser temperature drops below a preset temperature, the heater hybrid control is minimized to suppress the engine from starting. This is because the user perceives the temperature change more slowly in a resting state (e.g., sleeping state), and thus the necessity of performing rapid temperature control is small.

[0192] The processor 150 may increase the indoor temperature of the vehicle (S670). At this time, the processor 150 may consider the decrease in body temperature during rest and then increase the indoor temperature.

[0193] When the processor 150 determines that the air conditioner is not operating, it can determine whether the heater is operating ( S680 ). The processor 150 can confirm whether the heater is operating by communicating with the air conditioner controller 146 .

[0194] The processor 150 may use the electric heating element when it is determined that the heater is operating (S690). Even if the indoor temperature of the vehicle is lower than the set temperature, the processor 150 may use the electric heating element such as the PTC heater to adjust the indoor temperature of the vehicle as much as possible. In addition, when the vehicle is parked, even if the coolant temperature drops, the processor 150 may suppress the engine from starting, and when driving, the processor 150 may ensure the heat source by starting the engine.

[0195] The processor 150 may turn off the AAF to minimize the cooling of the coolant (S700). The AAF is a device for managing the heat of the engine compartment. If the coolant temperature rises, it is turned on to improve the cooling efficiency of the coolant by sucking in air. If the coolant temperature drops, it is turned off to reduce air resistance and improve fuel efficiency and / or power consumption efficiency.

[0196] The processor 150 may determine whether the current indoor temperature is lower than the preset resting suitable temperature (S710). The processor 150 may measure the current indoor temperature of the vehicle using the temperature sensor 113, and compare the measured current indoor temperature with the resting suitable temperature.

[0197] When the processor 150 determines that the current indoor temperature is lower than the preset resting suitable temperature, the engine start control may be executed (S720). The processor 150 may start the engine to provide heating to the vehicle interior when the current indoor temperature is lower than the preset resting suitable temperature.

[0198] The processor 150 may determine whether the current temperature in the vehicle reaches the resting suitable temperature (S730). The processor 150 may compare the current temperature in the vehicle with the "resting suitable temperature + α". When the comparison result shows that the current indoor temperature is consistent with the "resting suitable temperature + α", it may be determined that the current indoor temperature has reached the resting suitable temperature. The tolerance range may be determined to be within 10% of the resting suitable temperature due to hysteresis.

[0199] When the processor 150 determines that the current indoor temperature has reached the resting suitable temperature, it can execute the engine shut-off control (S740). That is, the processor 150 can shut down the engine 10 when the current indoor temperature reaches the resting suitable temperature.

[0200] According to the above embodiment, the vehicle control for rest after parking aims to minimize the factors that hinder the occupants from resting through the optimal control for resting, and control the vehicle in the best state so that the occupants can rest, which can prevent the air conditioning control and the engine from starting.

[0201] Figure 8 FIG. 4 is a flow chart showing a vehicle control method according to another embodiment of the present invention.

[0202] The processor 150 of the vehicle control device 100 may determine whether the user has selected to enter the rest mode (S810). The processor 150 may confirm whether a control instruction (or data) indicating the entry into the rest mode is received from the user interface 120. The processor 150 may determine that the user has selected to enter the rest mode when it is confirmed that a control instruction indicating the entry into the rest mode is received from the user interface 120. On the other hand, the processor 150 may determine that the user has not selected to enter the rest mode when it is confirmed that a control instruction indicating the entry into the rest mode is not received from the user interface 120.

[0203] When the processor 150 determines that the user has selected to enter the rest mode, it may determine whether to enter the driving rest mode based on the user input (or user selection) (S820). The processor 150 may determine whether to enter the driving rest mode according to the user's selection of the in-vehicle rest mode received from the user interface 120. The in-vehicle rest mode can be divided into a driving rest mode and a parking rest mode.

[0204] The processor 150 may perform vehicle control for resting while driving (S830) when determining to enter the resting mode while driving. The processor 150 may perform vehicle control such as electronic device load optimization control, engine start or stop control and / or SOC control after entering the resting mode while driving.

[0205] The processor 150 may perform vehicle control for resting while driving, and determine whether to end the rest mode (S840). The processor 150 may perform vehicle control for resting while driving, and use the camera 111 and / or the brain wave sensor 112 to identify the user status. The processor 150 may determine whether to end the rest mode based on the identified user status. For example, the processor 150 may determine to end the rest mode when the fatigue level of the user identified by the camera 111 and / or the brain wave sensor 112 is below a preset reference value. In addition, the processor 150 may determine to end the rest mode when a control instruction indicating to end the rest mode is received from the user interface 120. The processor 150 may end the vehicle control for resting in the vehicle when determining to end the rest mode.

[0206] When it is not determined in S820 to enter the rest mode during driving, the processor 150 may perform vehicle control for preparing to enter the rest mode after parking (S850). In other words, when it is determined in S820 to enter the rest mode after parking in the in-vehicle rest mode according to the user input received from the user interface 120, the processor 150 may perform vehicle control for preparing to enter the rest mode after parking. The processor 150 may perform vehicle control such as electronic equipment load optimization control, air conditioning control, and / or SOC control after entering the preparation mode for entering the rest mode after parking.

[0207] The processor 150 may determine whether the vehicle has arrived at a resting place (S860). The processor 150 may use the AVN 148 to determine whether the vehicle has arrived at a resting place. The AVN 148 may calculate the current position of the vehicle using a signal transmitted from a satellite. The AVN 148 may compare the calculated current position of the vehicle with the position of a resting place set as a destination to determine whether the vehicle has arrived at the resting place. The AVN 148 may transmit the result of determining whether the vehicle has arrived at the resting place to the processor 150. The processor 150 may determine whether the vehicle has arrived at the resting place based on the determination result transmitted from the AVN 148. The resting place, as a place where a vehicle can be parked, may be a resting space where a vehicle can rest after parking, such as a service area and / or a rest area.

[0208] When the processor 150 determines that the vehicle has arrived at the resting place, it can perform vehicle control for resting after parking (S870). After entering the resting mode after parking, the processor 150 can perform vehicle control such as electronic equipment load optimization control, SOC control and / or engine start and stop optimization control.

[0209] The processor 150 may perform vehicle control for rest after parking and determine whether to end the rest mode (S880). The processor 150 may determine the user state by analyzing the images obtained by the camera 111 and / or the brain wave sensor 112 and / or the brain wave analysis. The processor 150 may determine whether to end the rest mode based on the determined user state. For example, the processor 150 may determine to end the rest mode when the user state is converted from a sleeping state to a waking state. The processor 150 may end the vehicle control for rest after parking after determining to end the rest mode.
