A system and a method for controlling parameters of a vehicle according to an embodiment of the present invention are described in detail with reference to a technique for compensating or optimizing a parameter including an operation interval of a wiper for automatically controlling a wiper included in a vehicle However, the present invention is not limited thereto, and is merely an example for facilitating understanding of the present invention.

1 is a block diagram illustrating a system for controlling parameters of a vehicle according to an embodiment of the present invention.

Referring to FIG. 1, a system 10 for controlling parameters of a vehicle includes a sensor unit 100, a server 110, a determination unit 120, a control unit 130, a head unit 140, and a cluster 150 .

The sensor unit 100 measures data from the vehicle (child vehicle). For example, the sensor unit 100 may include a vehicle speed sensor, a humidity sensor, a right-handedness sensor, an indoor and an outdoor temperature sensor, which are merely examples for facilitating understanding of the present invention. Do not.

The server 110 classifies the parameters corresponding to the measured data from the sensor unit 100 and then extracts standard parameters from the classified parameters.

Here, the parameter may be a variable value or variable information, and may be an interval of operation of the wiper corresponding to the vehicle speed, humidity, and right-right slope, and the standard parameter may be named as a standard value, a representative parameter, However, the present invention is not limited thereto, and is merely an example for facilitating understanding of the present invention.

For example, the server 110 compares the measured data from the sensor unit 100 with the data classified by the server 100, and it is possible to match data measured from the vehicle among the data classified by the server 100, And data having the largest number of values within a predetermined range can be extracted as standard parameters.

For example, when the speed of the vehicle is 30 km / h, the humidity is 80%, and the right-right slope is 3 cd / sec, the operation interval of the wiper is 5 seconds and the speed of the vehicle is 30 km / , The operating interval of the wiper is 4.8 seconds, the vehicle speed is 40 km / h, the humidity is 80%, and the right-right slope is 4 cd / sec when the humidity is 85% and the right-right slope is 3 cd / The operation interval of the wiper is 3 seconds, the vehicle speed is 40 km / h, the humidity is 85%, and the rightward slope is 4 cd / sec, the operation interval of the wiper can be divided into 2.8 seconds.

For example, when the vehicle speed is 40 km / h, the humidity is 80%, and the right-right slope is 3 cd / sec, the operation interval of the wiper is 3 seconds and the number of stored data is 50 The operation interval of the wiper is 2.8 seconds when the vehicle speed is 40 km / h, the humidity is 80%, and the right-right slope is 3.5 cd / sec. When the number of stored data is 40 and the vehicle speed The standard parameter is extracted from the classified parameters including the case where the operation interval of the wiper is 2.5 seconds and the number of stored data is 20 when the humidity is 80% and the right-right slope is 4cd / sec. can do.

In other words, the standard parameter is that the operation interval of the wiper is 3 seconds and the number of stored data is 50 when the vehicle speed is 40 km / h, the humidity is 80%, and the right-right slope is 3 cd / sec. Among the classified data, data having the largest number of data measured from the vehicle or measured from the vehicle and a value within a predetermined range can be extracted as standard parameters.

The server 110 can receive the measured data from the other vehicle within the set range of the own vehicle or the set time of the vehicle and can receive the classified parameters of the vehicle or the extracted standard Parameter can be transmitted.

The determination unit 120 collects measured data from the sensor unit 100.

For example, the determination unit 120 may collect the position of the vehicle from the head unit 140 of the vehicle, collect the velocity of the vehicle from the cluster 150, and determine the humidity of the sensor unit 100 provided in the vehicle The sensor collects humidity information from a humidity sensor when it has sensors, a right-hand sensor, and indoor and outdoor temperature sensors, collects the right-quantity information from the right sensor, collects indoor and outdoor temperature information from indoor and outdoor temperature sensors, However, the present invention is not limited thereto, and is merely an example for facilitating understanding of the present invention.

The determination unit 120 determines whether the standard parameter selected by the server 110 is compensated for.

For example, when the current vehicle speed is 42 km / h, the humidity is 82%, and the right-right slope is 3 cd / sec, the determination unit 120 determines the standard parameters received from the server 110 Speed of 40 km / h, humidity of 80%, right angle slope of 3cd / sec and operation interval of the wiper is 3 seconds.

Here, when the vehicle is provided with a high-grade sensor (for example, a humidity sensor and a case where the right-handedness sensor is provided in the vehicle), the determination unit 120 determines compensation ), The compensation according to humidity (B) is performed, and the compensation (C) according to the rightward slope can be performed.

For example, the judging unit 120 judges whether or not the wiper compensated by the compensation (C) according to the operation interval (3 seconds) of the wiper + the compensation (A) Can be calculated.

Specifically, we can start with A = a0 (40-42) + a1, B = b0 (80-82) + b1 and C = c0 (3.2-3) + c1 and a0, b0, c0 are weights , and a1, b1, and c1 represent compensation constant values.

Here, if the vehicle is equipped with a supply-type sensor (for example, a humidity sensor and a case where the right-handedness sensor is not provided in the vehicle), the determination unit 120 determines whether compensation (A) can be carried out.

For example, the determination unit 120 may calculate the operation interval (compensation value) of the wiper compensated by the operation interval (3 seconds) of the wiper + the compensation (A) according to the vehicle speed.

Specifically, A = a0 (40 - 42) + a1, a0 is a weight value, and a1 is a compensation constant value.

The determination unit 120 can determine the right-right slope from the measured data from the sensor unit 100, and can determine whether the vehicle is equipped with the humidity sensor and the right-right sensor through the measured data.

The control unit 130 controls the components of the vehicle according to whether the standard parameters of the determination unit 120 are compensated. Here, the components of the vehicle may be wipers, which are merely examples for facilitating understanding of the present invention, and are not limited thereto.

The head unit 140 may be provided between the determination unit 120 and the server 110 and the cluster 150 may transmit the vehicle information including the speed of the vehicle to the determination unit 120 .

2 is a view for explaining a determination unit provided in a system for controlling parameters of a vehicle according to an embodiment of the present invention.

Referring to FIG. 2, the determination unit 120 collects measured data from the sensor unit 100 (S1). For example, the determination unit 120 may collect position information of the vehicle from the head unit 140 of the vehicle, collect velocity information of the vehicle from the cluster 150, The sensor collects humidity information from a humidity sensor when it has sensors, a right-hand sensor, and indoor and outdoor temperature sensors, collects the right-quantity information from the right sensor, collects indoor and outdoor temperature information from indoor and outdoor temperature sensors, can do.

For example, the right-handedness information may include a right-handed or right-handed gradient from the right-handed sensor through a TIR (Total Interval Reflection) measurement.

The determination unit 120 receives the standard parameters extracted from the server 110 (S2). For example, the determination unit 120 of the vehicle equipped with the high-grade sensor (for example, when the humidity sensor and the right-right sensor are provided) can determine the current vehicle speed, humidity, And the server 110 may extract standard parameters corresponding to the current vehicle speed, humidity, and right-right slope, and transmit the extracted standard parameters to the determination unit 120.

For example, if the current vehicle speed is 42 km / h and the humidity is 82%, the server 110 compares the measured data with the classified data to extract standard parameters corresponding to the measured data.

For example, when the vehicle speed is 40 km / h, the humidity is 80%, and the right-right slope is 3 cd / sec, the operation interval of the wiper is 3 seconds and the number of stored data is 50 The operation interval of the wiper is 2.8 seconds when the vehicle speed is 40 km / h, the humidity is 80%, and the right-right slope is 3.5 cd / sec. When the number of stored data is 40 and the vehicle speed The standard parameter is extracted from the classified parameters including the case where the operation interval of the wiper is 2.5 seconds and the number of stored data is 20 when the humidity is 80% and the right-right slope is 4cd / sec. can do.

In other words, the standard parameter is that the operation interval of the wiper is 3 seconds and the number of stored data is 50 when the vehicle speed is 40 km / h, the humidity is 80%, and the right-right slope is 3 cd / sec. Among the classified data, data having the largest number of data measured from the vehicle or measured from the vehicle and a value within a predetermined range can be extracted as standard parameters.

For example, the determination unit 120 of the vehicle provided with the low-level sensor (for example, when the humidity sensor and the right-right sensor are not provided) determines the current vehicle speed and the indoor / And transmits the temperature and humidity gradient to the server 110 based on the vehicle speed and the indoor / outdoor temperature. The server 110 extracts standard parameters (standard values) Lt; / RTI >

The determination unit 120 determines whether the extracted parameter is compensated (S3). For example, the determination unit 120 may determine whether or not the standard parameters including the operation interval of the wiper corresponding to the vehicle speed, humidity, and right-right slope, respectively, are compensated.

Specifically, the determination unit 120 can determine whether the vehicle is equipped with a high-grade sensor (for example, a humidity sensor and a right-right sensor) and determine whether the parameter is compensated. Further, (For example, when the humidity sensor and the right-hand-side sensor are not provided).

Hereinafter, Steps S11 to S17 described above will be described more specifically with reference to Fig.

In step S11, the determination unit 120 receives the measured data from the vehicle. For example, the measured data may include vehicle speed, humidity, right-handed volume, indoor and outdoor temperatures, which are merely examples for facilitating understanding of the present invention, and are not limited thereto.

In step S12, the determination unit 120 transmits the measured data to the server 110. [ Here, the server 110 classifies the parameters corresponding to the measured data from the sensor unit 100.

That is, the server 110 may classify parameters corresponding to the speed, humidity, and right-right slopes of the vehicle, respectively. For example, the parameter may be the operating interval of the wiper corresponding to the speed, humidity and right-right slope of the vehicle.

In step S13, the determination unit 120 receives the standard parameters extracted from the server 110. [

In step S14, the determination unit 120 determines whether the extracted standard parameter is compensated. For example, in the step of determining whether or not the extracted standard parameter is compensated, the determination unit 120 determines whether or not the standard parameter including the operation interval of the wiper corresponding to the vehicle speed, humidity, and right- can do.

In step S15, the controller 130 operates the components of the vehicle according to the compensated standard parameters of the determiner 120. [ For example, the control unit 130 may operate the wiper of the vehicle according to the compensated standard parameter of the determination unit 120, which is merely an example for facilitating understanding of the present invention, and is not limited thereto .
