The vehicle driving assistance apparatus 100 can control the actuator 400 in the process of performing the vehicle driving assistance function.

[0057] A specific description of the configuration and operation of the vehicle driving assistance apparatus 100 will be given below.

[0058] The information acquisition device 200 can acquire information (operation information) required for the operation of the vehicle driving assistance apparatus 100, and provide the acquired information to the vehicle driving assistance apparatus 100.

[0059] Figure 2 is a view showing the configuration of the information acquisition device 200 according to the embodiment of the present disclosure.

[0060] Referring to Figure 2 , the information acquisition device 200 can include a first information acquisition device 210, a second information acquisition device 220, and a third information acquisition device 230.

[0061] The first information acquisition device 210 can be implemented to acquire information input by a user (hereinafter, user input information). The first information acquisition device 210 can provide the acquired user input information to the vehicle driving assistance apparatus 100.

[0062] For example, the first information acquisition device 210 can include a user input interface 211 and a shift paddle 212. For example, the first information acquisition device 210 can be implemented to receive information about whether a vehicle driving assistance function is activated, information about a performance level of the vehicle driving assistance function, and information about a regenerative braking level. For example, the user input interface 211 can be a user setting manual (USM).

[0063] For example, the user input interface 211 can include a plurality of setting devices for receiving a user instruction for activating each of the vehicle driving assistance functions. For example, the user input interface 211 can include a first setting device for receiving an instruction for activating an intelligent cruise control (SCC) function, a second setting device for receiving an instruction for activating an intelligent regenerative braking system (SRS) function, and a third setting device for receiving an instruction for activating an inertia driving function.

[0064] As another example, the user input interface 211 can include one setting device for receiving a user instruction for activating all of the vehicle driving assistance functions.

[0065] The second information acquisition device 220 can be implemented to acquire information related to an environment in which the vehicle 1 travels (hereinafter, driving environment information). The second information acquisition device 220 can provide the acquired driving environment information to the vehicle driving assistance apparatus 100.

[0066] For example, the second information acquisition device 220 can acquire driving path information, road information about a driving path, vehicle surrounding information, vehicle position information, etc. For example, the second information acquisition device 220 can include a camera 221, an infrared sensor 222, a radar sensor 223, a laser radar sensor 224, a navigation system 225, and a global positioning system (GPS) module 226.

[0067] For example, the driving path information, the road information, the vehicle surrounding information, and the vehicle position information can be acquired by one device constituting the second information acquisition device 220, or can be acquired by combining information acquired by a plurality of devices.

[0068] The third information acquisition device 230 can be implemented to acquire state information of the vehicle 1 (hereinafter, vehicle state information). The third information acquisition device 230 can provide the acquired vehicle state information to the vehicle driving assistance apparatus 100.

[0069] For example, the third information acquisition device 230 may include a sensor (accelerator pedal position sensor (APS)) 231 for detecting the operation of the accelerator pedal, a sensor (brake pedal position sensor (BPS)) 232 for detecting the operation of the brake pedal, a sensor (gear sensor) 233 for detecting the gear position, a speed sensor 234 for detecting the speed of the vehicle 1 (vehicle speed), etc.

[0070] The output interface 300 can output information provided by the vehicle driving assistance device 100 according to preset settings.

[0071] For example, the output interface 300 can receive priority information about the vehicle's driving assistance functions from the vehicle driving assistance device 100 and output the received priority information.

[0073] like Figure 3 As shown, the output interface 300 may include any one of the audio-visual navigation (AVN) device 310, the dashboard 320, and the head-up display 330, and the type of the output interface 300 is not limited thereto.

[0076] like Figure 4 As shown, the actuator 400 may include a transmission device 410, an electric motor 420, an engine 430, etc., and the type of actuator 400 is not limited to these.

[0077] Figure 5 This is a diagram illustrating the configuration of a vehicle driving assistance device 100 according to an embodiment of the present disclosure.

[0078] The vehicle driving assistance device 100 can perform vehicle driving assistance functions by taking into account the driver's driving tendencies.

[0079] According to the implementation method, the vehicle driving assistance device 100 can determine the priority of vehicle driving assistance functions that cannot be executed simultaneously among the vehicle driving assistance functions, and execute the vehicle driving assistance function according to the determined priority.

[0080] The vehicle 1 can be equipped with two or more vehicle driving assistance functions that cannot be simultaneously performed.

[0081] For example, the vehicle driving assistance functions that cannot be simultaneously performed can include, but are not limited to, an intelligent cruise control (SCC) function, an intelligent regenerative braking system (SRS) function, an inertia driving function, etc.

[0082] Reference Figure 5 The vehicle driving assistance apparatus 100 can include a first communication device 110, a second communication device 120, a third communication device 130, a memory 140, and a controller 150, and the configuration of the vehicle driving assistance apparatus 100 is not limited thereto.

[0083] For example, the vehicle driving assistance apparatus 100 can be implemented as a hybrid control unit (HCU), a vehicle control unit (VCU), or an electric control unit (ECU).

[0084] The first communication device 110 can communicate with the information acquisition apparatus 200, receive information provided from the information acquisition apparatus 200, and transmit the received information to the controller 150.

[0085] For example, the first communication device 110 can be composed of one or more communication modules. The one or more communication modules can communicate with the information acquisition apparatus 200 based on a preset communication protocol. For example, the first communication device 110 can communicate with the information acquisition apparatus 200 based on a communication protocol such as a local interconnect network (LIN), a controller area network (CAN), FlexRay, Ethernet, etc.

[0086] The second communication device 120 can communicate with the output interface 300 and provide information provided from the controller 150 to the output interface 300.

[0087] For example, the second communication device 120 can be composed of one or more communication modules. The one or more communication modules can communicate with the information acquisition apparatus 200 based on a preset communication protocol. For example, the second communication device 120 can communicate with the output interface 300 based on a communication protocol such as a local interconnect network (LIN), a controller area network (CAN), FlexRay, Ethernet, etc.

[0088] The third communication device 130 can communicate with the actuator 400 and output a control signal to the actuator 400.

[0089] For example, the third communication device 130 can be composed of one or more communication modules. The one or more communication modules can communicate with the actuator 400 based on a preset communication protocol. For example, the third communication device 130 can communicate with the actuator 400 based on a communication protocol such as a local interconnect network (LIN), a controller area network (CAN), FlexRay, Ethernet, etc.

[0090] The memory 140 can store algorithms, data, etc. for performing operations of the controller 150.

[0091] The memory 140 can include a volatile memory and / or a non-volatile memory. The volatile memory can include a dynamic random access memory (DRAM), a static RAM (SRAM), a synchronous DRAM (SDRAM), a phase change RAM (PRAM), a magnetic RAM (MRAM), a resistive RAM (RRAM), and a ferroelectric RAM (FeRAM). The non-volatile memory can include a read only memory (ROM), a programmable ROM (PROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), and a flash memory.

[0092] The controller 150 can perform a vehicle driving assistance function according to an algorithm stored in the memory 140. The controller 150 can perform the vehicle driving assistance function using information provided from the information acquisition device 200.

[0093] The controller 150 can be implemented as at least one processor. The at least one processor can be a hardware data processing apparatus including a circuit having a physical structure for performing a desired operation. For example, the desired operation can include code or instructions included in a program.

[0094] For example, the hardware data processing apparatus can include a microprocessor, a central processing unit, a processor core, a multi-core processor, a multi-processor, an application specific integrated circuit (ASIC), and a field programmable gate array (FPGA).

[0095] According to an embodiment, the controller 150 can determine whether to activate a vehicle driving assistance function based on operation information provided from the information acquisition device 200.

[0096] For example, the controller 150 can determine whether to activate a vehicle driving assistance function based on user input information provided from the user input interface 211 of the first information acquisition device 210. For example, the controller 150 can determine whether an intelligent cruise control (ICC) function, an intelligent regenerative braking system (SRS) function, and an inertia driving function are activated based on whether information on activation of the vehicle driving assistance function is included in the user input information.

[0097] According to an embodiment, upon determining that all of the preset vehicle driving assistance functions are activated, the controller 150 can determine whether a deceleration event occurs within a preset distance (e.g., 1 km) based on operation information provided from the information acquisition device 200.

[0098] For example, the controller 150 can determine whether a deceleration event occurs based on the driving environment information provided from the second information acquisition device 220.

[0099] For example, the controller 150 can determine whether a deceleration event occurs within a preset distance based on the presence or absence of a preceding vehicle, the presence or absence of a toll gate, the presence or absence of a deceleration lane, the presence or absence of a speed measurement camera, and the presence or absence of an intersection.

[0100] In this way, the controller 150 can determine that a deceleration event occurs when it is determined that the preset obstacle or obstacle section is present within the preset distance.

[0101] According to an embodiment, when it is determined that all of the preset vehicle driving assistance functions have been activated, the controller 150 can count the number of shift knob operations and the number of neutral driving based on the operation information provided from the information acquisition device 200.

[0102] For example, the controller 150 can count the number of shift knob operations based on the operation signal provided from the shift knob 212 of the first information acquisition device 210. For example, the controller 150 can count the number of neutral driving based on the neutral gear signal provided from the gear sensor 233 of the third information acquisition device 230.

[0103] When a user operation for regenerative braking of the vehicle 1 is performed, the shift knob 212 can output an operation signal, and when the vehicle 1 is in neutral, the gear sensor 233 can output a neutral gear signal.

[0104] According to an embodiment, when it is determined that a deceleration event occurs within a preset distance, the controller 150 can compare a current vehicle speed with a preset threshold speed based on the operation information provided from the information acquisition device 200, and determine whether the current vehicle speed is less than the threshold speed.

[0105] For example, the controller 150 can compare the current vehicle speed with the threshold speed based on the speed information provided from the speed sensor 234 of the third information acquisition device 230.

[0106] The controller 150 can calculate a score of an accelerator pedal or a score of a brake pedal based on a result of the comparison between the current vehicle speed and the threshold speed (i.e., a result of determining whether the current vehicle speed is lower than the threshold speed).

[0107] For example, if the current vehicle speed is less than the threshold speed, the controller 150 can calculate the score of the accelerator pedal, and if the current vehicle speed is equal to or greater than the threshold speed, the controller 150 can calculate the score of the brake pedal.

[0108] The controller 150 can calculate a score for the accelerator pedal based on the driving environment information provided from the second information acquisition device 220 and accelerator pedal operation information provided from the accelerator pedal position sensor 231 of the third information acquisition device 230.

[0109] For example, the controller 150 can calculate the score for the accelerator pedal based on at least two pieces of information among an accelerator pedal operation count, an accelerator pedal stroke, an accelerator pedal operation time, and a remaining distance from a current position of the vehicle 1 to a point at which a deceleration event occurs.

[0110] For example, the controller 150 can calculate the accelerator pedal score A according to the following mathematical expression 1. However, the method of calculating the accelerator pedal score A is not limited thereto.

[0111] [mathematical expression 1]

[0112] A = a1 * (operation count / remaining distance) + a2 * (stroke * operation time / remaining distance)

[0113] In the mathematical expression 1, a1 and a2 are weights set through experiments applied when calculating the accelerator pedal score A.

[0114] The controller 150 can calculate a score for the brake pedal based on the driving environment information provided from the second information acquisition device 220 and brake pedal operation information provided from the brake pedal position sensor 232 of the third information acquisition device 230.

[0115] For example, the controller 150 can calculate the score for the brake pedal based on at least two pieces of information among a brake pedal operation count, a brake pedal stroke, a brake pedal operation time, and a remaining distance from a current position of the vehicle to a point at which a deceleration event occurs.

[0116] For example, the controller 150 can calculate the brake pedal score B according to the following mathematical expression 2. However, the method of calculating the brake pedal score B is not limited thereto.

[0117] [mathematical expression 2]

[0118] B = b1 * (operation count / remaining distance) + b2 * (stroke * operation time / remaining distance)

[0119] In the mathematical expression 2, b1 and b2 are weights set through experiments applied when calculating the brake pedal score.

[0120] According to an embodiment, the controller 150 can determine a driving mode based on the accelerator pedal score A, the brake pedal score B, the shift paddle operation count C, and the neutral driving count D, and determine a priority of the vehicle driving assistance function based on the driving mode.

[0121] According to an embodiment, the driving mode can be expressed as a score or an index as described below.

[0122] Before determining the priority of the vehicle driving assistance function, the controller 150 can calculate an acceleration index E and a braking index F based on at least two of the accelerator pedal score A, the brake pedal score B, the shift paddle operation count C, and the neutral driving count D. The acceleration index E and the braking index F can be referred to as a driving mode score.

[0123] Further, the controller 150 can determine the priority of the vehicle driving assistance function based on the acceleration index E and the braking index F.

[0124] In other words, the controller 150 can calculate an acceleration index E and a braking index F based on at least two of the accelerator pedal score A, the brake pedal score B, the shift paddle operation count C, and the neutral driving count D, and can determine the priority of the vehicle driving assistance function based on the calculated acceleration index E and the braking index F.

[0125] For example, the controller 150 can calculate the acceleration index E based on the accelerator pedal score A and the neutral driving count D.

[0126] For example, the controller 150 can calculate the acceleration index E according to the following mathematical expression 3. However, the method of calculating the acceleration index E is not limited thereto.

[0127] [Mathematical Expression 3]

[0128] E = Accelerator pedal score A - e1*Neutral driving count D

[0129] In the mathematical expression 3, e1 is a weight set through an experiment applied when calculating the acceleration index E.

[0130] For example, the controller 150 can calculate the braking index F based on the brake pedal score B, the shift paddle operation count C, and the neutral driving count D.

[0131] For example, the controller 150 can calculate the braking index F according to the following mathematical expression 4. However, the method of calculating the braking index F is not limited thereto.

[0132] [Mathematical Expression 4]

[0133] F = Brake pedal score B - f1*Neutral driving count D + f2*Shift paddle operation count C

[0134] In mathematical expression 4, f1 and f2 are experimentally set weights applied when calculating the braking index F.

[0135] According to the implementation, in a driving mode that has the characteristic of coasting driving being preferred for deceleration events, the controller 150 can determine that the inertial driving function has a higher priority than other vehicle driving assistance functions.

[0136] According to the implementation, in a driving mode characterized by frequent use of the brake pedal and driving below critical speeds preferred to decelerate, the controller 150 can determine that the priority of the intelligent regenerative braking function is higher than the priority of other vehicle driving assistance functions.

[0137] According to the implementation, in a driving mode where the accelerator pedal and brake pedal are not frequently used for deceleration events, the controller 150 can determine that the priority of the intelligent cruise control function is higher than the priority of other vehicle driving assistance functions.

[0138] According to the implementation method, in a driving mode characterized by frequent use of paddle shifters, the controller 150 can determine that the priority of the intelligent regenerative braking function is higher than the priority of other vehicle driving assistance functions.

[0139] According to the implementation method, in a driving mode characterized by frequent neutral driving, the controller 150 can determine that the priority of the inertial driving function is higher than the priority of other vehicle driving assistance functions.

[0140] Table 1 summarizes the priorities of vehicle driving assistance functions determined according to embodiments of the present disclosure.

[0141] [Table 1]

[0142]

[0143] As shown in Table 1, if the acceleration index E is less than the preset first reference value (or acceleration index reference value) 1 and the braking index F is less than the preset second reference value (or braking index reference value) k, the controller 150 can determine to prioritize the execution of the inertial driving function.

[0144] If the acceleration index E is less than the first reference value l and the braking index F is equal to or greater than the second reference value k, the controller 150 can determine to prioritize the execution of the intelligent regenerative braking function.

[0145] If the acceleration index E is equal to or greater than the first reference value l, the controller 150 can determine to prioritize the execution of the intelligent cruise control function, regardless of the braking index F.

[0146] The first reference value I and the second reference value k can be set through experiments with various conditions in order to be used to determine which vehicle driving assist function is useful according to the driving pattern.

[0147] In this way, the priority determination according to the embodiment of the disclosure is that when the acceleration index E is high, the intelligent cruise control function can be preferentially executed, when only the brake index F is high, the intelligent regenerative brake function can be preferentially executed, and when both the acceleration index E and the brake index F are low, the inertia driving function can be preferentially executed.

[0148] According to the embodiment, since when both the acceleration index E and the brake index F are low, the priority requirement of the inertia driving function is set to be higher than the priorities of the other vehicle driving assist functions (this is a case of increasing the priority of the inertia driving), the neutral driving count D can be applied as a subtraction (-) parameter to the formulas (mathematical expressions 3 and 4) for calculating the acceleration index E and the brake index F.

[0149] According to the embodiment, since when only the brake index F is high, the priority requirement of the intelligent regenerative brake function is set to be higher than the priorities of the other vehicle driving assist functions (this is a case of increasing the priority of the intelligent regenerative brake), the shift paddle operation count C can be applied as an addition (+) parameter to the formula (mathematical expression 4) for calculating the brake index F.

[0150] According to the embodiment, the controller 150 can determine the priorities of the vehicle driving assist functions using the driving pattern score G that is the sum of the accelerator pedal score A and the brake pedal score B.

[0151] Therefore, the controller 150 can determine the priorities of the vehicle driving assist functions based on the driving pattern score G, the shift paddle operation count C, and the neutral driving count D.

[0152] If the driving pattern score G is less than a preset first comparison value m (G < m), the controller 150 can determine that the priority of the inertia driving function is higher than the priorities of the other vehicle driving assist functions.

[0153] However, even if the driving pattern score G is less than the first comparison value m (G < m), if the shift paddle operation count C is greater than a first limit value o (C > o), the controller 150 can determine that the priority of the intelligent regenerative brake function is higher than the priorities of the other vehicle driving assist functions.

[0154] In other words, if the driving pattern score G is smaller than the first comparison value m (G < m), the controller 150 can determine that the priority of the inertia driving function is higher than the priority of the other vehicle driving assist functions, and if the shift paddle operation count C is greater than the first limit value o (C > o), the priority of the intelligent regenerative braking function is determined to be higher than the priority of the other vehicle driving assist functions.

[0155] The shift paddle operation count C is related to the frequency of execution of the intelligent regenerative braking function, and a larger shift paddle operation count C means that the intelligent regenerative braking function is frequently executed.

[0156] In this way, the shift paddle operation count C can be applied to determine the priority of the vehicle driving assist functions to reflect the driving pattern of the user who frequently executes the intelligent regenerative braking function.

[0157] If the driving pattern score G is equal to or greater than the first comparison value m and smaller than a preset second comparison value n (m ≤ G < n), the controller 150 can determine that the priority of the intelligent regenerative braking function is higher than the priority of the other vehicle driving assist functions.

[0158] However, even if the driving pattern score G is equal to or greater than the first comparison value m and smaller than the second comparison value n (m ≤ G < n), if the neutral driving count D is greater than a preset second limit value p (D > p), the controller 150 can determine that the priority of the inertia driving function is higher than the priority of the other vehicle driving assist functions.

[0159] In other words, if the driving pattern score G is equal to or greater than the first comparison value m and smaller than the second comparison value n (m ≤ G < n), the controller 150 can determine that the priority of the intelligent regenerative braking function is higher than the priority of the other vehicle driving assist functions, and if the neutral driving count D is greater than a preset second limit value p (D > p), the priority of the inertia driving function is determined to be higher than the priority of the other vehicle driving assist functions.

[0160] The neutral driving count D is related to the frequency of execution of the inertia driving function, and a larger neutral driving count D means that the inertia driving function is frequently executed.

[0161] In this way, the neutral driving count D can be applied to determine the priority of the vehicle driving assist functions to reflect the driving pattern of the user who frequently executes the inertia driving function.

[0162] If the driving pattern score G is equal to or greater than the second comparison value n (G ≥ n), the controller 150 can determine that the priority of the intelligent cruise control function is higher than the priority of the other vehicle driving assist functions.

[0163] However, even if the driving mode score G is equal to or greater than the second comparison value n (G ≥ n), if the shift paddle operation count C is greater than the first limit value o (C > o), the controller 150 can determine that the priority of the smart regenerative braking function is higher than the priority of the other vehicle driving assistance function.

[0164] In other words, if the driving mode score G is equal to or greater than the second comparison value n (G ≥ n), the controller 150 can determine that the priority of the smart cruise control function is higher than the priority of the other vehicle driving assistance function, and if the shift paddle operation count C is greater than 0 (C > 0), the controller 150 can determine that the priority of the smart regenerative braking function is higher than the priority of the other vehicle driving assistance function.

[0165] In an embodiment, the first comparison value m and the second comparison value n can be set through experiments with various conditions in order to determine which vehicle driving assistance function is useful according to the driving manner.

[0166] In an embodiment, the first limit value o can be set through experiments with various conditions for determining whether the priority of the smart regenerative braking function is higher than the priority of the other vehicle driving assistance function.

[0167] In an embodiment, the second limit value p can be set through experiments with various conditions for determining whether the priority of the inertia driving function is higher than the priority of the other vehicle driving assistance function.

[0168] According to an embodiment, after determining the priority of the vehicle driving assistance function, the controller 150 can execute the vehicle driving assistance function according to a preset vehicle driving assistance function execution strategy.

[0169] According to an embodiment, after determining the priority of the vehicle driving assistance function, the controller 150 can execute the vehicle driving assistance function based on the priority of the vehicle driving assistance function from the next deceleration event.

[0170] According to an embodiment, the controller 150 can continuously update the priority of the vehicle driving assistance function every time a deceleration event occurs, and when the number of updates reaches a preset update threshold, the vehicle driving assistance function can be executed based on the priority of the vehicle driving assistance function from the next deceleration event.

[0171] According to an embodiment, the controller 150 can execute the vehicle driving assistance function based on the priority initially preset or determined in the previous cycle until the number of updates of the priority reaches the update threshold.

[0172] The controller 150 can control the actuator 400 according to the executed vehicle driving assistance function. When the actuator 400 is controlled by the controller 150 in this manner, the vehicle 1 can travel based on inertia driving, intelligent regenerative braking, or intelligent cruise control.

[0173] According to an embodiment, the controller 150 can provide vehicle driving assistance function execution operation information to the output interface 300. Accordingly, the output interface 300 can output the vehicle driving assistance function execution operation information. For example, the vehicle driving assistance function operation information can include priority information about the vehicle driving assistance function, and information included in the vehicle driving assistance function operation information is not limited thereto.

[0190] Upon determining that the deceleration event does not occur within a preset distance (step S630 - No), the vehicle driving assistance device 100 can determine whether the preset vehicle driving assistance function is activated based on the operation information (step S610).

[0191] Upon determining that the deceleration event occurs within a preset distance (step S630 - Yes), the vehicle driving assistance device 100 can determine whether the vehicle speed is less than a preset threshold speed based on the operation information (step S640).

[0192] For example, the vehicle driving assistance device 100 can determine whether the vehicle speed is less than the threshold speed based on the speed information provided from the speed sensor 234 of the third information acquisition device 230.

[0193] If the vehicle speed is less than the threshold speed (step S640 - Yes), the vehicle driving assistance device 100 can calculate an accelerator pedal score based on the operation information (step S650).

[0194] In step S650, the vehicle driving assistance device 100 can calculate the accelerator pedal score based on the driving environment information provided from the second information acquisition means 220 and the accelerator pedal operation information provided from the accelerator pedal position sensor 231 of the third information acquisition means 230.

[0196] If the vehicle speed is equal to or greater than the threshold speed (step S640 - No), the vehicle driving assistance device 100 can calculate a brake pedal score based on the operation information (step S660).

[0197] In step S660, the vehicle driving assistance device 100 can calculate the brake pedal score based on the driving environment information provided from the second information acquisition means 220 and the brake pedal operation information provided from the brake pedal position sensor 232 of the third information acquisition means 230.

[0208] Referring to Figure 7 , the vehicle driving assistance device 100 can determine the priority for the vehicle driving assistance function based on the accelerator pedal score, the brake pedal score, the shift paddle operation count, and the neutral driving count.

[0209] Specifically, the vehicle driving assistance device 100 can calculate an acceleration index E based on the accelerator pedal score A and the neutral driving count D (step S671), and calculate a braking index F based on the brake pedal score B, the shift paddle operation count C, and the neutral driving count D (step S672).

[0224] If the driving mode score G is smaller than the first comparison value m (G < m), the vehicle driving assist device 100 can determine that the priority of the inertia driving function is higher than the priority of the other vehicle driving assist functions (step S675).

[0225] According to the embodiment, in step S675, the vehicle driving assist device 100 can further compare the shift paddle operation count C with a preset first limit value o.

Further, if the shift paddle operation count C is equal to or smaller than the first limit value o (C ≤ o), the vehicle driving assist device 100 can determine that the priority of the inertia driving function is higher than the priority of the other vehicle driving assist functions.
