This application claims the benefit of Korean Patent Application No. 10-2023-0181224, filed on Dec. 13, 2023, which application is hereby incorporated herein by reference.
The present disclosure relates to a vehicle control apparatus and a method thereof.
Among the parts of a vehicle, only tires are in contact with the ground surface and serve to generate a driving force through their friction forces and absorb shock through elasticity. It is very important to manage the tires for safe driving.
The air pressure of the tires of the vehicle has a great influence on the performance and safety of the tires. The tires of the vehicle may be measured by tire air pressure sensors. Each of the tire air pressure sensors may be mounted for each wheel of the vehicle to measure pressure, a temperature, or the like of each of the tires to provide a driver of the vehicle with the measured information. The driver may manage the air pressure of each wheel by means of the information provided by the tire air pressure sensors.
An existing technology may determine which wheel of the vehicle the tire air pressure sensor is mounted on using wheel speed sensors. Wheel pulse information measured by the wheel speed sensor mounted for each wheel of the vehicle may be differently measured as the movement of each wheel varies. As such, the existing technology may determine which wheel the tire air pressure sensor is mounted on using the wheel pulse information differently measured for each wheel.
However, when the wheel speed sensor is used and when a problem occurs in controller area network (CAN) communication of the vehicle or the vehicle does not drive at a certain speed or more, it is difficult to determine which wheel the tire air pressure sensor is mounted on.
Meanwhile, recently, the vehicle is loaded with a function capable of determining a position of a smart key of the vehicle using a low frequency (LF) antenna mounted on the door of the driver's seat, the door of the passenger seat, a trunk, or the like or locking or unlocking a door of the vehicle using the smart key present within a certain distance from the vehicle.
The present disclosure relates to a vehicle control apparatus and a method thereof. Particular embodiments relate to technologies for a tire pressure sensor.
Embodiments of the present disclosure can solve problems occurring in the prior art while advantages achieved by the prior art are maintained intact.
An embodiment of the present disclosure provides a vehicle control apparatus for reducing costs by using an LF antenna mounted on a vehicle, without a separate additional sensor, and a method thereof.
Another embodiment of the present disclosure provides a vehicle control apparatus for improving stability by using an LF antenna which is not influenced by an error in wheel pulse, an error in CAN communication, or the like and a method thereof.
Another embodiment of the present disclosure provides a vehicle control apparatus for receiving information about tire pressure even immediately after the vehicle is started by using an LF antenna capable of transmitting a signal even while the vehicle is not traveling and a method thereof.

Hereinafter, embodiments of the present disclosure will be described in detail with reference to
According to an embodiment, a vehicle control apparatus 100 may include a processor 110, a memory 120, a low frequency (LF) antenna 130, a tire pressure sensor 140, and a receiver 150. The components of the vehicle control apparatus 100, which are shown in
According to an embodiment, the memory 120 may store a command or data. For example, the memory 120 may store one instruction or two or more instructions that, when executed by the processor 110, cause the vehicle control apparatus 100 to perform various operations.
According to an embodiment, the memory 120 and the processor 110 may be implemented as one chipset and may store various pieces of information associated with the vehicle control apparatus 100. For example, the memory 120 may store information about an operation history of the processor 110.
According to an embodiment, the memory 120 may include a non-volatile memory (e.g., a read only memory (ROM)) and a volatile memory (e.g., a random access memory (RAM)). For example, the pressure of a tire or the like, which is measured by the tire pressure sensor 140, may be stored in the memory 120.
According to an embodiment, the plurality of tire pressure sensors 140 may be mounted on a plurality of wheels of a vehicle. For example, the tire pressure sensor 140 may be mounted for each wheel of the vehicle. As a detailed example, when the number of wheels of the vehicle is four, each of a total of four tire pressure sensors 140 may be mounted for each wheel.
According to an embodiment, the plurality of LF antennas 130 may transmit an LF signal for triggering each of the plurality of tire pressure sensors 140.
According to an embodiment, the triggering may include an operation of being automatically performed when a database meets a predetermined condition or when a certain operation is performed.
For example, the tire pressure sensor 140 may be configured to be triggered when receiving the LF signal from the LF antenna 130. As a detailed example, upon receiving the LF signal in a state in which low power is used, the tire pressure sensor 140 may switch to a state in which rated power is used. As another detailed example, upon receiving the LF signal in a state in which any signal is not transmitted, the tire pressure sensor 140 may transmit a radio frequency (RF) signal. This is only an embodiment. In addition, the triggering may be set to connect various conditions with various operations.
According to an embodiment, the LF antennas 130 may trigger the plurality of tire pressure sensors 140 which receive the LF signal. For example, the tire pressure sensor 140 may be triggered whenever receiving the LF signal. As a detailed example, when the tire pressure sensor 140 is configured to transmit the RF signal whenever receiving the LF signal, it may transmit the RF signal several times upon receiving the plurality of LF signals.
According to an embodiment, the receiver 150 may drive the plurality of LF antennas 130 to receive the RF signal. For example, the receiver 150 may include an independent processor capable of driving the LF antenna 130.
For example, when power is applied to the vehicle, the receiver 150 may cause the LF antenna 130 to transmit the LF signal. The LF antenna 130 may be driven by the receiver 150.
According to an embodiment, the receiver 150 may receive the RF signal. For example, the receiver 150 may receive the RF signal transmitted by the tire pressure sensor 140 and may deliver the RF signal to the processor 110.
According to an embodiment, each LF antenna 130 included in the plurality of LF antennas 130 may transmit the LF signal to at least some of the plurality of tire pressure sensors 140 present in an area where a transmit signal of each LF antenna 130 is reached.
According to an embodiment, the area where the transmit signal of the LF antenna 130 is able to be reached may be set by a system or a user. For example, the area where the transmit signal of the LF antenna 130 is able to be reached may be set by software and may be physically set by a coil or the like constituting the LF antenna 130. As a detailed example, the area where the transmit signal of the LF antenna 130 is able to be reached may be set to an oval-shaped area with a long axis and a short axis depending on a physical shape of the LF antenna 130 or a setting of software.
According to an embodiment, the processor 110 may set the area where the LF signal transmitted by the LF antenna 130 is able to be reached. Thus, the processor 110 may set the area where the LF signal of the LF antenna 130 is able to be reached, such that the LF signal is able to be reached in only a specific wheel of the vehicle.
As a detailed example, the processor 110 may set the area where the transmit signal of the LF antenna 130 is able to be reached such that only a front wheel located at the left of the vehicle and a rear wheel located at the left of the vehicle are able to receive the LF signal. As another detailed example, the processor 110 may set the area where the transmit signal of the LF antenna 130 is able to be reached such that only a front wheel located at the right of the vehicle and a rear wheel located at the right of the vehicle are able to receive the LF signal. As another detailed example, the processor 110 may set the area where the transmit signal of the LF antenna 130 is able to be reached such that only the rear wheel located at the left of the vehicle and the rear wheel located at the right of the vehicle are able to receive the LF signal.
According to an embodiment, at least some of the plurality of tire pressure sensors 140 may receive the LF signal transmitted by the LF antenna 130. For example, the tire pressure sensor 140 which receives the LF signal transmitted by the specific LF antenna 130 may be one in number and may be plural in number.
According to an embodiment, upon receiving the LF signal, each of the plurality of tire pressure sensors 140 may transmit the RF signal to the receiver 150.
For example, the tire pressure sensor 140 may include a communication interface capable of receiving the LF signal. Thus, there may be no need for a separate sensor for receiving the LF signal.
For example, the tire pressure sensor 140 may transmit the RF signal to the receiver 150 whenever receiving the LF signal. Thus, even when the tire pressure sensor 140 which already transmits the RF signal to the receiver 150 upon receiving the LF signal transmitted by the specific LF antenna 130 receives the LF signal transmitted by the other LF antenna 130, it may retransmit the RF signal to the receiver 150.
According to an embodiment, each of the plurality of tire pressure sensors 140 may transmit the RF signal, including a unique ID of each of the plurality of tire pressure sensors 140 or a pressure value of the tire, which is measured by each of the plurality of tire pressure sensors 140, or any combination thereof, to the receiver 150.
For example, the tire pressure sensor 140 may have a unique ID value. The tire pressure sensor 140 may transmit the RF signal including information about the unique ID to the receiver 150. The receiver 150 may distinguish the tire pressure sensor 140 in light of the unique ID.
For example, the tire pressure sensor 140 may measure the pressure of the tire. The tire pressure sensor 140 may transmit the RF signal, including the pressure value of the tire, to the receiver 150.
According to an embodiment, the processor 110 may determine which wheel of the plurality of wheels of the vehicle each of the plurality of tire pressure sensors 140 is mounted on, based on the RF signal received from the at least some of the plurality of tire pressure sensors 140 present in the area where the transmit signal of each LF antenna 130 is reached.
According to an embodiment, the plurality of LF antennas 130 may include a first LF antenna, a second LF antenna, and a third LF antenna. For example, the first LF antenna may be located on a door of the driver's seat of the vehicle, the second LF antenna may be located on a door of the passenger seat of the vehicle, and the third LF antenna may be located on a trunk of the vehicle.
According to an embodiment, the processor 110 may set the area where the transmit signal of each of the LF antennas 130 is able to be reached. For example, the processor 110 may set a first area where the transmit signal of the first LF antenna is able to be reached, may set a second area where the transmit signal of the second LF antenna is able to be reached, and may set a third area where the transmit signal of the third LF antenna is able to be reached.
According to an embodiment, the processor 110 may set an extent of at least one of the first area, the second area, or the third area, or any combination thereof, based on vehicle information including an overall length of the vehicle, an overall width of the vehicle, or an overall height of the vehicle, or any combination thereof.
For example, the overall length of the vehicle may indicate the entire length of the vehicle and may include a length from a front part of the vehicle to a rear part of the vehicle. The overall width of the vehicle may indicate the entire width of the vehicle and may include a width from the left of the vehicle to the right of the vehicle. The overall height of the vehicle may indicate the entire height of the vehicle and may include a height from the top point of the vehicle to the bottom of the vehicle.
For example, the processor 110 may set the first area where the transmit signal of the first LF antenna is able to be reached to include a tire pressure sensor of a left front wheel tire and a tire pressure sensor of a left rear wheel tire. At this time, when the overall length of the vehicle is relatively long and the overall width of the vehicle is relatively narrow, the processor 110 may set the first area to be an oval in which a width in the direction of the overall length is relatively longer than a width in the direction of the overall width with respect to the first LF antenna.
According to an embodiment, the processor 110 may set the area where the transmit signal of each of the LF antennas 130 is able to be reached, such that only two tire pressure sensors 140 are included in the area where the transmit signal of each of the LF antennas 130 is able to be reached. Only the tire pressure sensor 140 present in the area where the transmit signal is able to be reached may receive the LF signal of the LF antenna 130.
According to an embodiment, the first LF antenna may transmit the LF signal to the plurality of tire pressure sensors present in the first area where the transmit signal of the first LF antenna is reached.
For example, the processor 110 may set the first area such that only the tire pressure sensor of the left front wheel tire of the vehicle and the tire pressure sensor of the left rear wheel tire of the vehicle receive the transmit signal of the first LF antenna. In this case, upon receiving the LF signal, only the tire pressure sensor of the left front wheel tire and the tire pressure sensor of the left rear wheel tire may transmit the RF signal, including a unique ID of each of the tire pressure sensors, to the receiver 150.
According to an embodiment, the second LF antenna may transmit the LF signal to the plurality of tire pressure sensors present in the second area where the transmit signal of the second LF antenna is reached.
For example, the processor 110 may set the second area such that only the tire pressure sensor of the right front wheel tire of the vehicle and the tire pressure sensor of the right rear wheel tire of the vehicle receive the transmit signal of the second LF antenna. In this case, upon receiving the LF signal, only the tire pressure sensor of the right front wheel tire and the tire pressure sensor of the right rear wheel tire may transmit the RF signal, including a unique ID of each of the tire pressure sensors, to the receiver 150.
According to an embodiment, the third LF antenna may transmit the LF signal to the plurality of tire pressure sensors present in the third area where the transmit signal of the third LF antenna is reached.
For example, the processor 110 may set the third area such that only the tire pressure sensor of the left rear wheel tire of the vehicle and the tire pressure sensor of the right rear wheel tire of the vehicle receive the transmit signal of the third LF antenna. In this case, upon receiving the LF signal, only the tire pressure sensor of the left rear wheel tire and the tire pressure sensor of the right rear wheel tire may transmit the RF signal, including a unique ID of each of the tire pressure sensors, to the receiver 150.
According to an embodiment, the processor 110 may determine the plurality of tire pressure sensors, which transmit the RF signal based on the transmit signal of the first LF antenna, as at least one of the tire pressure sensor mounted on the left front wheel of the vehicle or the tire pressure sensor mounted on the left rear wheel of the vehicle, or any combination thereof.
For example, there may be the left front wheel of the vehicle and the left rear wheel of the vehicle in the first area where the transmit signal of the first LF antenna located on the door of the driver's seat is reached. In this case, the tire pressure sensor mounted on the left front wheel and the tire pressure sensor mounted on the left rear wheel may transmit the RF signal including information about the unique ID of each of the tire pressure sensors.
According to an embodiment, the processor 110 may determine the plurality of tire pressure sensors, which transmit the RF signal based on the transmit signal of the second LF antenna, as at least one of the tire pressure sensor mounted on the right front wheel of the vehicle or the tire pressure sensor mounted on the right rear wheel of the vehicle, or any combination thereof.
For example, there may be the right front wheel of the vehicle and the right rear wheel of the vehicle in the second area where the transmit signal of the second LF antenna located on the door of the passenger seat is reached. In this case, the tire pressure sensor mounted on the right front wheel and the tire pressure sensor mounted on the right rear wheel may transmit the RF signal including information about the unique ID of each of the tire pressure sensors.
According to an embodiment, the processor 110 may determine the plurality of tire pressure sensors, which transmit the RF signal based on the transmit signal of the third LF antenna, as at least one of the tire pressure sensor mounted on the left rear wheel of the vehicle or the tire pressure sensor mounted on the right rear wheel of the vehicle, or any combination thereof.
For example, there may be the left rear wheel of the vehicle and the right rear wheel of the vehicle in the third area where the transmit signal of the third LF antenna located on the trunk is reached. In this case, the tire pressure sensor mounted on the left rear wheel and the tire pressure sensor mounted on the right rear wheel may transmit the RF signal including information about the unique ID of each of the tire pressure sensors.
According to an embodiment, the processor 110 may sequentially drive the first LF antenna, the second LF antenna, and the third LF antenna by means of the receiver 150 and may determine a wheel on which the tire pressure sensor 140 is mounted.
For example, the processor 110 may sequentially trigger the tire pressure sensor mounted on the left front wheel and the tire pressure sensor mounted on the left rear wheel by means of the LF signal of the first LF antenna located on the door of the driver's seat, may sequentially trigger the tire pressure sensor mounted on the right front wheel and the tire pressure sensor mounted on the right rear wheel by means of the LF signal of the second LF antenna located on the door of the passenger seat, and may sequentially trigger the tire pressure sensor mounted on the left rear wheel and the tire pressure sensor mounted on the right rear wheel by means of the LF signal of the third LF antenna located on the trunk.
As a detailed example, the processor 110 may determine the tire pressure sensor 140, which transmits the RF signal based on only the transmit signal of the first LF antenna, as the tire pressure sensor mounted on the left front wheel of the vehicle.
As a detailed example, the processor 110 may determine the tire pressure sensor 140, which transmits the RF signal based on only both the transmit signal of the first LF antenna and the transmit signal of the third LF antenna, as the tire pressure sensor mounted on the left rear wheel of the vehicle.
As a detailed example, the processor 110 may determine the tire pressure sensor 140, which transmits the RF signal based on only the transmit signal of the second LF antenna, as the tire pressure sensor mounted on the right front wheel of the vehicle.

According to an embodiment, there may be another vehicle around a host vehicle loaded with the vehicle control apparatus 100. When there is another vehicle at a distance adjacent to the host vehicle, a tire pressure sensor of the other vehicle may be triggered by the LF signal transmitted by the LF antenna 130 of the host vehicle. In this case, the receiver 150 of the host vehicle may receive an RF signal transmitted by the tire pressure sensor of the other vehicle. Thus, there is a need to determine whether there is another vehicle around the host vehicle.
According to an embodiment, the processor 110 may determine whether there is another vehicle within a predetermined distance from the vehicle, using at least one of a camera mounted on the outside of the vehicle or an ultrasonic sensor mounted on the outside of the vehicle, or any combination thereof.
For example, the camera mounted on the outside of the vehicle may include cameras, such as a built-in camera, a front view camera, a rear view camera, a mono camera, and a stereo camera provided in the vehicle, which are capable of capturing or detecting the periphery of the vehicle.
For example, the ultrasonic sensor mounted on the outside of the vehicle may include a distance sensor for sensing a distance between the vehicle and a surrounding object. The ultrasonic sensor may include a sensor capable of sensing that a surrounding object approaches the vehicle. As a detailed example, the ultrasonic sensor may include a parking assistance system (PAS) sensor.
For example, the predetermined distance from the vehicle may be set in light of the area where the transmit signal of the LF antenna 130 is able to be reached. As a detailed example, the predetermined distance from the vehicle may be set to a distance at which the tire pressure sensor of the other vehicle is able to receive the transmit signal of the LF antenna 130 of the host vehicle.
According to an embodiment, when three or more different RF signals are received in the receiver 150, based on the LF signal transmitted by any one of the plurality of LF antennas 130, the processor 110 may determine that the RF signal transmitted by the tire pressure sensor of the other vehicle is included in the received different RF signals.
For example, when it is identified that unique IDs included in the three or more RF signals received through the receiver 150 are different from each other, the processor 110 may determine that the three or more different RF signals are received.
For example, when the three different RF signals are received in the receiver 150, for the LF signal transmitted by the first LF antenna located on the door of the driver's seat of the host vehicle, the processor 110 may determine that another RF signal, which does not correspond to the tire pressure sensor 140 mounted on the left front wheel of the host vehicle and the tire pressure sensor 140 mounted on the left rear wheel of the host vehicle, is included. In this case, unless there is a special circumstance, the processor 110 may determine that the RF signal transmitted by the tire pressure sensor of the other vehicle is received in the receiver 150.
For example, although determining that the RF signal transmitted by the tire pressure sensor of the other vehicle is included in the three or more different RF signals received through the receiver 150, the processor 110 may fail to distinguish whether any of the three or more different RF signals corresponds to the RF signal received from the tire pressure sensor 140 of the host vehicle. Thus, there is an additional need to determine the RF signal received from the tire pressure sensor 140 of the host vehicle among the three or more different RF signals.
According to an embodiment, the processor 110 may drive the plurality of LF antennas 130 by means of the receiver 150 to retransmit the LF signal, after a predetermined time from a time point when the RF signal transmitted by the tire pressure sensor of the other vehicle is received, based on the RF signal transmitted by the tire pressure sensor of the other vehicle being included in the received different RF signals.
For example, the predetermined time may be set to a sufficient time when another vehicle is unable to be present within a distance adjacent to the host vehicle. As a detailed example, while the host vehicle and the other vehicle are traveling, the predetermined time may be set in light of a speed of the host vehicle and a speed of the other vehicle. As another detailed example, while the host vehicle and the other vehicle are parking or while the host vehicle and the other vehicle are stopping, the predetermined time may be set to a time when the host vehicle or the other vehicle starts and are unable to be adjacent to each other.
According to an embodiment, when driving the plurality of LF antennas 130 by means of the receiver 150 to retransmit the LF signal, the processor 110 may drive all the plurality of LF antennas 130 loaded into the vehicle and may drive only the LF antenna 130 triggered to transmit three or more different RF signals.
According to an embodiment, when two different RF signals among the three or more different RF signals are re-received in the receiver 150, based on the retransmitted LF signal, the processor 110 may determine that the re-received two different RF signals are received from the tire pressure sensor 140 of the host vehicle.
For example, when the two different RF signals are re-received in the receiver 150 based on the retransmitted LF signal, there may be no other vehicle around the host vehicle. Thus, the processor 110 may determine that the re-received two different RF signals are received from the tire pressure sensor 140 of the host vehicle.
As a detailed example, when the unique ID included in the re-received two different RF signals is identical to the unique ID included in the three or more different RF signals which are previously received, the processor 110 may determine that the re-received two different RF signals are received from the tire pressure sensor 140 of the host vehicle.
According to an embodiment, the processor 110 may drive the plurality of antennas 130 by means of the receiver 150 to retransmit the LF signal, based on it being determined that the other vehicle is no longer within the predetermined distance from the host vehicle, after it is determined that the RF signal transmitted by the tire pressure sensor of the other vehicle is received.
For example, the processor 110 may determine whether there is another vehicle within the predetermined distance from the host vehicle, using the camera mounted on the outside of the host vehicle, the ultrasonic sensor mounted on the outside of the host vehicle, or the like. In detail, the processor 110 may continuously identify another vehicle present within the predetermined distance by means of the camera, the ultrasonic sensor, or the like.
For example, when it is determined that there is no longer the other vehicle within the predetermined distance from the host vehicle, the processor 110 may drive the LF antennas 130 again by means of the receiver 150 to receive only the RF signal transmitted by the tire pressure sensor 140 of the host vehicle. At this time, the processor 110 may drive all the plurality of LF antennas 130 loaded into the host vehicle and may drive only the LF antenna 130 triggered to transmit three or more RF signals. The driven LF antenna 130 may retransmit the LF signal.
According to an embodiment, when two different RF signals among the three or more different RF signals are re-received in the receiver 150, based on the retransmitted LF signal, the processor 110 may determine that the re-received two different RF signals are received from the tire pressure sensor 140 of the host vehicle.
For example, when the unique ID included in the re-received two different RF signals is identical to the unique ID included in the three or more different RF signals which are previously received, the processor 110 may determine that the re-received two different RF signals are received from the tire pressure sensor 140 of the host vehicle.
According to an embodiment, a position of a tire pressure sensor 240 might be conventionally determined using a wheel speed sensor 260. For example, a receiver 250 may receive information about a wheel pulse from the wheel speed sensor 260.
According to an embodiment, the wheel speed sensor 260 may be mounted for each wheel of the vehicle. Wheel pulse information may be differently measured according to the movement of each wheel. For example, when the vehicle turns left or right, a rotational speed of a wheel at the left of the vehicle and a rotational speed of a wheel at the right of the vehicle may be different from each other. Thus, the wheel pulse information may be differently measured.
As such, the receiver 250 may determine which wheel the wheel speed sensor 260 is mounted on, using the wheel pulse information differently measured for each wheel.
According to an embodiment, the tire pressure sensor 240 may measure at least one of pressure of a tire or a temperature of the tire, or any combination thereof, and may transmit the measured information as an RF signal to the receiver 250. The receiver 250 may determine a position of the tire pressure sensor 240 interworking with the wheel speed sensor 260, using the wheel pulse information.
However, because the wheel speed sensor 260 transmits information using CAN communication, when an error occurs in the CAN communication or when the wheel speed sensor 260 fails, it is difficult for a processor to determine a position of the tire pressure sensor 240.
Furthermore, because the wheel speed sensor 260 is able to operate as the vehicle travels, it is difficult for a processor to determine a position of the tire pressure sensor 240 while stopping.
According to an embodiment, the smart key system may allow a user who has a smart key 310 to perform a door or trunk opening and closing function of the vehicle, using an LF signal or an RF signal. In addition, the smart key system may perform various functions of starting an engine using the smart key 310 or providing a service interworking with a smartphone.
For example, LF antennas may be loaded into a door of the driver's seat of the vehicle, a door of the passenger seat of the vehicle, and a trunk of the vehicle. In detail, a first LF antenna 331 may be loaded into the door of the driver's seat, a second LF antenna 332 may be loaded into the door of the passenger seat, and a third LF antenna 333 may be loaded into the trunk.
According to an embodiment, a receiver 350 may drive the first LF antenna 331, the second LF antenna 332, or the third LF antenna 333. The driven LF antenna may transmit an LF signal.
Upon receiving the LF signal transmitted by the LF antenna, the smart key 310 may transmit an RF signal. At this time, information about a function of operating a door of the vehicle or starting the vehicle may be included in the RF signal.
The receiver 350 may receive the RF signal transmitted by the smart key 310. The receiver 350 may control the vehicle to perform an operation associated with the function included in the RF signal. Alternatively, the receiver 350 may transmit related data to a separate processor capable of performing an operation associated with the function.

Herein, the area 560 where the LF signal transmitted by the LF antenna 530 is able to be reached may be set to an oval with a short-axis radius R1 and a long-axis radius R2.
