Description

Technology Field

[0001] The present invention relates to a shift position detection system for an electric shift lever system and a method of operation thereof. More specifically, it relates to a shift position detection system for an electric shift lever system and a method of operation thereof, which, in a vehicle equipped with an electric shift lever system (Shift By Wire, SBW), subdivides the shift position learning process according to the position of the shift lever and allows a main controller (e.g., ECU, VCU, etc.) to check the progress of the learning, thereby enabling more accurate estimation of the shift position in the electric shift lever system. Background Technology

[0003] Unlike mechanical shift lever systems that utilize mechanical link structures such as wires, electric shift lever systems perform gear changes using electrical signals.

[0004] Specifically, an electric shift lever system refers to a system that transmits operation information from the shift lever as an electrical signal to rotate a motor and switch gears, thereby enabling the driver to achieve desired states such as parking or driving; as it minimizes shifting shock and vibration, the number of vehicles adopting this system is gradually increasing.

[0005] FIG. 1 is a diagram illustrating the general configuration of an electric shift lever system. Referring to FIG. 1, the electric shift lever system may generally include a shift lever sensor that detects an electrical signal caused by the operation of the shift lever by the driver, a position sensor of the motor (e.g., a Hall sensor), and a Shift by wire control unit (SCU) that rotates the motor to enable a transition to a specific gear requested by the driver based on the signal received from the shift lever sensor.

[0006] When a request to switch gear range is input during driving, the SCU of the electric shift lever system calculates the target duty of the motor based on signals received from the motor position sensor and the shift lever sensor so that the shift lever switches to a specific gear according to the driver's request, and controls the operation of the motor based on the calculated target duty value.

[0007] For example, the SCU of an electric shift lever system adopts feedback control (Closed-Loop Control) in general situations, such as driver requests, and controls the motor's operation so that the motor's rotation angle matches the target rotation angle by applying a duty value to the motor based on the difference between the motor's rotation angle provided by the position sensor and the motor's target rotation angle. In special cases, such as the initial learning mode, it rotates the motor to the appropriate position by applying a pre-set constant duty command through open-loop control.

[0008] Meanwhile, since such conventional electric shift lever systems lack a separate absolute position sensor and determine the current position of the gear (e.g., P or Not P) through shift position learning, a highly reliable learning logic is required. The problem to be solved

[0010] The present invention aims to solve the above problem by providing a shift position detection system for an electric shift lever system and a method of operation thereof, which subdivides the shift position learning process according to the position of the shift lever in a vehicle equipped with an electric shift lever system (Shift By Wire, SBW) and allows a main controller (e.g., ECU, VCU, etc.) to check the progress of the learning, thereby enabling more accurate estimation of the shift position in the electric shift lever system.

Specific details for implementing the invention

[0035] Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions would hinder understanding of the embodiments of the present invention, such detailed description is omitted. Additionally, while embodiments of the present invention will be described below, the technical concept of the present invention is not limited thereto and can be modified and implemented in various ways by those skilled in the art.

[0036] Throughout the specification, when a part is described as being "connected" to another part, this includes not only cases where they are "directly connected," but also cases where they are "indirectly connected" with other elements interposed between them. Throughout the specification, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Furthermore, in describing the components of the embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc., may be used. These terms are used merely to distinguish the component from other components, and the essence, order, or sequence of the component is not limited by such terms.

[0038] FIG. 2 is a flowchart illustrating the configuration of a gear shift position detection system and its operation method according to one embodiment of the present invention.

[0039] Referring to FIG. 2, the gear shift position detection system of an electric gear shift lever system may be composed of a position learning control unit (100) that performs gear shift position learning by applying an arbitrary duty to a vehicle motor, and a main control unit (200) that determines the gear shift position of the gear shift lever by receiving the results of the learning progress by the position learning control unit (100).

[0040] According to various embodiments, the position learning control unit (100) can perform gear shift position learning by applying a control signal corresponding to an arbitrary duty value to the vehicle motor according to the Hall sensor signal of the Hall sensor provided in the vehicle motor, thereby driving the vehicle motor to rotate to an appropriate position.

[0041] Specifically, the position learning control unit (100) can perform shift position learning normally by rotating the vehicle motor so that the detent plate is blocked by a wall and no longer moves, and then checking the point in time when no change in the Hall sensor signal is detected. Such a position learning control unit (100) can be implemented as a SCU (shift by wire control unit).

[0042] According to various embodiments, the position learning control unit (100) may initiate gear shift position learning in the P stage or Not P stage. For example, the P stage means that the gear shift lever is positioned in the main gear, and the Not P stage means that the gear shift lever is positioned in a gear other than the main gear.

[0043] The main control unit (200) determines whether the gear shift position learning is being performed normally based on the gear shift position learning result received from the position learning control unit (100), and can estimate the gear shift position of the gear shift lever based on the signal received from the position learning control unit (100).

[0044] For example, the main control unit (200) can check whether each signal output from the position learning control unit (100) is output within a preset time, and determine whether the gear position of the shift lever is in the P position or not in the P position according to each signal.

[0045] Additionally, the main control unit (200) determines whether the gear shift position learning is being performed normally based on each signal output from the position learning control unit (100), and may output a control signal corresponding to the abnormal situation to the position learning control unit (100) or an external controller (not shown) when an abnormal situation occurs in the vehicle.

[0046] That is, the main control unit (200) can be implemented as a vehicle control unit (VCU) or an electronic control unit (ECU) that is equipped in the vehicle and transmits major commands to various control components.

[0047] Below, the operation method of the position learning control unit (100) and the main control unit (200) described above will be described in more detail.

[0048] Each of the following operations may be performed sequentially, but is not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0049] Referring again to FIG. 2, in operation S310, the main control unit (200) can generate a learning command signal to initiate gear shift position learning in the position learning control unit (100) and transmit it to the position learning control unit (100). The learning command signal at this time may be, for example, a first learning command signal.

[0050] In operation S320, the position learning control unit (100) can generate a learning start signal by initiating gear shift position learning by applying a preset duty to the vehicle motor in response to a learning command signal. Then, in operation S330, the position learning control unit (100) can transmit the generated learning start signal to the main control unit (200).

[0051] For example, if the main control unit (200) does not receive a learning start signal from the position learning control unit (100) within a preset time from the time the first learning command signal is transmitted, it may generate a learning command signal to restart the gear shift position learning and transmit it to the position learning control unit (100). At this time, the learning command signal may be, for example, a second learning command signal. That is, if a learning start signal is transmitted from the position learning control unit (100) within a preset time from the time the first learning command signal is transmitted, the main control unit (200) can confirm that the gear shift position learning has been successfully started.

[0052] When gear shift position learning is successfully initiated, the position learning control unit (100) can generate a learning signal in operation S340 and transmit it to the main control unit (200).

[0053] For example, when the position learning control unit (100) starts learning the shift position in the Not P stage, it can sequentially generate a first learning signal, a second learning signal, and a learning end signal according to the Hall sensor signal and transmit them to the main control unit (200).

[0054] Additionally, for example, when the position learning control unit (100) starts learning the shift position in the P stage, it can generate a learning end signal based on the Hall sensor signal and transmit it to the main control unit (200).

[0055] That is, in operation S350, the position learning control unit (100) can generate a learning end signal indicating that the gear shift position learning has been successfully completed and transmit it to the main control unit (200).

[0056] In operation S360, the main control unit (100) determines whether each signal received from the position learning control unit (100) is received within a preset time, and can determine the gear position of the gear lever based on the result of the determination.

[0057] According to various embodiments, when learning the gear shift position starts in the Not P stage, if the main control unit (200) does not receive a first learning signal within a preset time after receiving a learning start signal from the position learning control unit (100), the gear shift position of the gear lever can be determined as the Not P stage.

[0058] In this case, the main control unit (200) receives sensing data from a sensor (e.g., a gradient sensor or a gyroscope sensor) that detects the slope of the vehicle driving road and determines whether the vehicle is currently located on a slope. If it is determined that the vehicle is currently located on a slope, it can generate a brake control signal to apply the vehicle brake and transmit it to an electric parking brake controller (EPB) that controls the vehicle brake.

[0059] That is, when the main control unit (200) determines that the vehicle is currently parked on an incline and that the gear lever is in the Not P position, it generates a brake control signal to apply the vehicle brake and transmits it to a controller that controls the vehicle brake, thereby preventing the vehicle from rolling back.

[0060] According to various embodiments, the main control unit (200) can determine that the gear shift position learning is performed normally only after receiving a learning start signal from the position learning control unit (100), receiving a first learning signal within a set time, and receiving a second learning signal within a preset time after receiving the first learning signal. For example, if the main control unit (200) does not receive a second learning signal from the position learning control unit (100) within a preset time, it can determine the gear shift position of the gear lever to the P position.

[0061] Additionally, according to various embodiments, if the main control unit (200) does not receive a learning end signal from the position learning control unit (100) within a preset time, it can determine the gear position of the gear lever to the P position.

[0062] In this case, the main control unit (200) determines that the vehicle motor has been terminated after the detent plate passes through the P stage, and can control the vehicle motor to rotate in the Not P stage direction, for example, in the opposite direction to the rotational driving direction of the motor when learning the gear shift position.

[0063] Additionally, according to various embodiments, when gear shift position learning is started in the P stage, if the main control unit (200) does not receive a learning end signal within a preset time after receiving a learning start signal from the position learning control unit (100), the position learning control unit (100) may determine that gear shift position learning has not been performed normally.

[0064] In this case, the main control unit (200) may generate a learning command signal to restart gear shift position learning and transmit it to the position learning control unit (100). The learning command signal at this time may be a second learning command signal transmitted after the first learning command signal has been transmitted.

[0065] Below, we will describe in more detail the signal output from the position learning control unit (100) when the shift position learning is performed normally in the Not P stage and the P stage.

[0067] FIGS. 3 and 4 are drawings illustrating a signal output from a position learning control unit when shift position learning is performed normally when shift position learning starts at the Not P stage, according to an embodiment of the present invention.

[0068] Referring to FIGS. 3 and 4, when learning the gear shift position at the Not P gear (410), the position learning control unit (100) can start learning the gear shift position in response to a learning command signal from the main control unit (200), and then generate a learning start signal and transmit it to the main control unit (200).

[0069] Subsequently, if the position learning control unit (100) determines based on the Hall sensor signal that the detent plate is located at the P-end ridge (420) between the Not P-end ridge (410) and the P-end ridge (430), it can generate a first learning signal within a preset first setting time (t1) and transmit it to the main control unit (200).

[0070] According to various embodiments, if the main control unit (200) does not receive a first learning signal within a first setting time (t1), it determines the gear position of the gear lever to Not P and receives sensing data from a sensor that detects the inclination of the vehicle driving road to determine whether the vehicle is currently located on an incline.

[0071] For example, if the main control unit (200) determines that the vehicle is currently on an incline while the gear lever is in the Not P position, it can generate a brake control signal to apply the vehicle brake and transmit it to the electronic parking brake controller (EPB).

[0072] When the gear shift position learning is performed normally, the position learning control unit (100) can generate a second learning signal within a preset second setting time (t2) based on the time when the first learning signal was transmitted and transmit it to the main control unit (200).

[0073] For example, if the position learning control unit (200) outputs a first learning signal and determines that the detent plate is located at the P-end (430) based on the Hall sensor signal, it can generate a second learning signal within a second setting time (t2).

[0074] At this time, if the main control unit (200) does not receive a second learning signal from the position learning control unit (100) within a second setting time (t2), the gear position of the gear lever can be determined as the P position.

[0075] When the gear shift position learning is successfully performed again, the position learning control unit (100) can generate a learning termination signal and transmit it to the main control unit (200) within a preset third setting time (t3) based on the time when the second learning signal is output, when the detent plate is in contact with the P wall (440) based on the Hall sensor signal, that is, when no change in the Hall sensor signal is detected. In this case, the main control unit (200) can determine that the gear shift position learning has been successfully terminated.

[0076] In contrast, if a learning termination signal is not received within the third set time (t3), the main control unit (200) determines that the vehicle motor has been terminated after the detent plate passes through the P stage, and at the same time determines the gear position of the gear lever to the P stage, can control the vehicle motor to rotate in the Not P stage direction.

[0078] FIGS. 5 and 6 are drawings illustrating signals output from a position learning control unit when shift position learning is performed normally when shift position learning starts at the P stage, according to an embodiment of the present invention.

[0079] Referring to FIGS. 5 and 6, when learning the gear shift position at the P-stage (610), the position learning control unit (100) can start learning the gear shift position in response to a learning command signal from the main control unit (200), and then generate a learning start signal and transmit it to the main control unit (200).

[0080] Subsequently, when the position learning control unit (100) detects that the detent plate is in contact with the P wall (620) based on the Hall sensor signal, that is, that no change in the Hall sensor signal is detected, it can generate a learning end signal within a preset fourth setting time (t4) based on the time when the learning start signal was output and transmit it to the main control unit (200). In this case, the main control unit (200) can determine the gear position of the gear lever to the P position and determine that the gear position learning has been successfully completed.

[0081] In contrast, if a learning termination signal is not received within the fourth set time (t4), the main control unit (200) determines that the gear shift position learning has not been performed normally and may generate a learning command signal to restart the gear shift position learning and transmit it to the position learning control unit (100). At this time, the learning command signal may, for example, refer to a second learning command signal that is output after the first learning command signal is transmitted.

[0083] As described above, according to the shift position detection system of an electric shift lever system and the method of operation thereof according to one embodiment of the present invention, the shift position learning process based on the position of the shift lever in a vehicle equipped with an electric shift lever system (Shift By Wire, SBW) is subdivided, and the learning progress is checked by a main controller (e.g., ECU, VCU, etc.), thereby allowing the shift position in the electric shift lever system to be estimated more accurately.

[0084] In addition, according to the present invention, by ensuring that the gear shift position learning of the electric shift lever system is performed normally, there is an effect of preventing the unnatural feeling of shifting caused by a control reset that occurs during gear shift position learning.

[0086] Those skilled in the art to which the present invention pertains should understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features, and therefore the embodiments described above should be understood as illustrative in all respects and not restrictive.
