Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to an integrated corner sensor combination switch and a control method thereof.

[0002] Background With Technology With the rapid development of intelligent driving technology, more and more modern cars are equipped with independent steering angle sensors, which are mainly used to accurately identify the steering angle of the vehicle. This technological advancement is crucial to the realization of Advanced Driving Assistance System (ADAS) and autonomous driving functions. As a key component of the vehicle stability control system, the steering angle sensor can effectively suppress the rear wheel side slip (self-rotation phenomenon) and front wheel side slip (drift phenomenon) that may occur in emergency situations such as sharp steering operations or sudden changes in road conditions through four-wheel independent automatic pressure braking control and engine torque control. At the same time, it can also prevent the folding phenomenon when the tractor brakes, ensuring the driving stability of the car under various road conditions.

[0003] The steering angle sensor is usually installed at the bottom of the steering column and can detect the steering wheel's turning angle, steering direction and speed. When the driver turns the steering wheel, the sensor monitors the steering action in real time and sends this data to the vehicle's Electronic Control Unit (ECU). The ECU adjusts the vehicle's dynamic performance based on this information, such as by adjusting the braking system or engine output to keep the vehicle stable.

[0004] Turn angle sensors play an irreplaceable role in improving vehicle safety and driving experience, but the R&D and production costs of independent turn angle sensors are relatively high. This includes not only the cost of the sensor itself, but also the cost of related software development for integration into the vehicle's electronic system. Therefore, although turn angle sensors have laid the foundation for the development of intelligent driving technology, their addition has also invisibly increased the cost of the entire vehicle.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0021] First, some nouns involved in this application are analyzed: The vehicle combination switch (also called a multi-function switch or steering column switch) is an integrated device used to control multiple functions on a car. It is usually located on the steering column behind the steering wheel and can be operated by turning, rotating or pressing. The combination switch can mainly control the following functions: Turn signal lights: Control the left and right turn signals by toggling the switch left or right.

[0022] Headlights: Adjust the light brightness and turn it on and off. Some models can also control automatic headlights, daytime running lights and other functions through this switch.

[0023] Wipers and washers: Controls wiper speed and water spray for front and rear windshields.

[0024] Cruise control: Some high-end models may also have integrated cruise control or adaptive cruise control functions.

[0025] Information display: The combination switch of some models also integrates the control buttons for the instrument panel information display.

[0026] The clock spring, also known as a spiral cable assembly or airbag coil, is an important component in modern cars. Its role is to ensure the continuity of the electrical connection when the steering wheel is turned, especially important when it comes to airbag systems and other electrical components on the steering wheel (such as horns, cruise control buttons, etc.). The clock spring utilizes a spiral cable design that allows the steering wheel to rotate freely while keeping the wires from getting tangled or broken. The clock spring usually contains a central axis and a shell that rotates around the central axis. Inside is a spiral conductive path or flat cable that is connected to the electrical components in the steering wheel and is able to expand and contract as the steering wheel turns.

[0027] A 3D Hall sensor is a sensor that can detect magnetic fields in three dimensions. It is usually designed to measure the strength of the magnetic field on the X, Y, and Z axes, and can calculate the relative position, angle, or other characteristics of the magnetic field based on this information. The working principle of the 3D Hall sensor is based on the Hall effect, that is, when an electric current passes through a semiconductor material placed in a magnetic field, a voltage is generated in a direction perpendicular to the current and the magnetic field. This voltage is called the Hall voltage. The magnitude of the Hall voltage is proportional to the current passing through the material and the strength of the magnetic field. By measuring the magnetic field components in three mutually perpendicular directions, the 3D Hall sensor can determine the position or direction of a point in three-dimensional space. This type of sensor is suitable for applications that require high-precision position detection.

[0028] A steering angle sensor is a sensor used to measure or monitor the rotation angle of an object. In the automotive field, it is usually installed on the steering column or inside the steering gear to detect the center position, rotation direction, rotation angle and rotation speed of the steering wheel. It is crucial in active safety systems (such as ESP body stability system), assisted driving systems (such as lane keeping assist), and autonomous driving technology.

[0029] With the rapid development of intelligent driving technology, more and more modern cars are equipped with independent steering angle sensors, which are mainly used to accurately identify the steering angle of the vehicle. This technological advancement is crucial to the realization of Advanced Driving Assistance System (ADAS) and autonomous driving functions. As a key component of the vehicle stability control system, the steering angle sensor can effectively suppress the rear wheel side slip (self-rotation phenomenon) and front wheel side slip (drift phenomenon) that may occur in emergency situations such as sharp steering operations or sudden changes in road conditions through four-wheel independent automatic pressure braking control and engine torque control. At the same time, it can also prevent the folding phenomenon when the tractor brakes, ensuring the driving stability of the car under various road conditions.

[0030] The steering angle sensor is usually installed at the bottom of the steering column and can detect the steering wheel's turning angle, steering direction and speed. When the driver turns the steering wheel, the sensor monitors the steering action in real time and sends this data to the vehicle's Electronic Control Unit (ECU). The ECU adjusts the vehicle's dynamic performance based on this information, such as by adjusting the braking system or engine output to keep the vehicle stable.

[0031] Turn angle sensors play an irreplaceable role in improving vehicle safety and driving experience, but the R&D and production costs of independent turn angle sensors are relatively high. This includes not only the cost of the sensor itself, but also the cost of related software development for integration into the vehicle's electronic system. Therefore, although turn angle sensors have laid the foundation for the development of intelligent driving technology, their addition has also invisibly increased the cost of the entire vehicle.

[0032] Based on this, the embodiment of the present application provides an integrated turn angle combination switch and a control method thereof, aiming to realize the integration of the turn angle sensor and the combination switch, improve the integration of vehicle components, and reduce the vehicle production cost.

[0033] The integrated corner sensor combination switch and the control method thereof provided in the embodiment of the present application are specifically described through the following embodiments. First, the integrated corner sensor combination switch in the embodiment of the present application is described.

[0034] Please refer to Figure 1 , is a schematic diagram of the structure of an integrated angle sensor combination switch provided in an embodiment of the present application, such as Figure 1 As shown, the integrated rotation angle sensor combination switch 100 in the embodiment of the present application may include but is not limited to: a clock spring module 110 , a combination switch module 120 and a steering wheel 130 .

[0035] The clock spring module 110 includes a stator 111 and a rotor 112 with a magnetic component 113 . The magnetic component 113 can rotate with the rotor 112 to cause a change in the magnetic field. The combination switch module 120 includes a magnetic sensing unit 121 .

[0036] It should be noted that, in the embodiment of the present application, the stator 111 of the clock spring module 110 is directly fixedly connected to the combination switch module 120 , and the rotor 112 is connected to the steering wheel 130 .

[0037] It can be understood that, since the rotor 112 of the clock spring module 110 is provided with the magnetic component 113 and is connected to the steering wheel 130, when the steering wheel rotates, the rotor 112 is driven, and then the magnetic component 113 is driven to rotate, so that the magnetic field changes; the clock spring module 110 is connected to the combination switch module 120, and the stator 111 is fixedly connected to the combination switch module 120. When the magnetic field changes, the magnetic sensing unit 121 of the combination switch module 120 can receive the magnetic force change caused by the magnetic component 113, thereby generating an angle signal according to the magnetic force change.

[0038] The rotor 112 of the clock spring module 110 is provided with a magnetic component 113, and the steering wheel 130 is connected to the rotor 112, so that when the user controls the steering wheel 130 to rotate, the rotor 112 is driven to rotate and the magnetic component 113 is driven to rotate accordingly, causing a magnetic force change. The stator 111 of the clock spring module 110 is directly connected to the combination switch module 120, and the magnetic force sensing unit 121 provided in the combination switch module 120 receives the magnetic force change caused by the magnetic component 113 and directly converts it into an angle signal, so that the combination switch can realize angle sensing without the need to independently design an angle sensing system, thereby reducing the manufacturing cost of the vehicle.

[0039] It should be noted that in a feasible embodiment of the present application, the magnetic sensing unit may include but is not limited to: a sensing device, a correction device and a signal processing device.

[0040] Please refer to Figure 2 , is a partial structural top view of an integrated angle sensor combination switch provided in an embodiment of the present application, such as Figure 2 As shown, in the integrated corner combination switch provided in the embodiment of the present application, the magnetic sensing unit 121 includes a sensing device 122 , a correction device 123 and a signal processing device 124 .

[0041] It can be understood that in the embodiment of the present application, the sensing device 122 is used to receive the magnetic force changes to generate an initial angle signal, the correction device 123 is used to receive the magnetic force changes to generate a correction signal, and the signal processing device 124 is used to receive the initial angle signal and the correction signal, and generate an angle signal based on the initial angle signal and the correction signal.

[0042] By arranging the sensing device 122 to receive the magnetic force change to generate the initial rotation angle signal, and the correcting device 123 to receive the magnetic force change to generate the correction signal, the accuracy of the generated rotation angle signal can be guaranteed and the occurrence of erroneous sensing can be avoided.

[0043] It should be noted that, in the embodiment of the present application, the magnetic component 113 disposed on the rotor 112 of the clock spring module 110 may be a magnet or a magnetic strip. The magnet or magnetic strip is connected to the rotor 112 by an embedding method. The magnetic component 113 is disposed at one end of the rotor 112 of the clock spring module 110 close to the combination switch module 120.

[0044] It can be understood that the magnetic component 113 in the embodiment of the present application can also be an electromagnet component. If an electromagnet component is used as the magnetic component 113, the clock spring module 110 needs to be electrically connected to the combination switch module 120. When the vehicle is started, the clock spring module 110 is energized to start the electromagnet, so that the magnetic component 113 starts to work. The user can therefore control the angle of the vehicle. The steering lock of the vehicle can be achieved through the electromagnet component. When the vehicle is not started by the user, the steering of the vehicle is locked to prevent the vehicle from being stolen.

[0045] In the embodiment of the present application, the use of a magnetic strip or a magnet as the magnetic component 113 can realize a simple structure for vehicle angle sensing. When an electromagnet component is used as the magnetic component 113, it is possible to improve vehicle safety while realizing angle sensing using a magnetic structure, so that the steering function of the vehicle can be locked when the vehicle is not unlocked by the user, thereby preventing theft.

[0046] Please refer to Figure 3 , for the embodiment of this application Figure 1 The structural diagram of the combined switch module 120 is as follows: Figure 3 As shown, the combined switch module 120 provided in the embodiment of the present application includes, in addition to the magnetic sensing unit 121 including the sensing device 122 , the correction device 123 and the signal processing device 124 , a communication module 140 , which includes a main chip 141 and a communication chip 142 .

[0047] Among them, the main chip 141 is connected to the combination switch module 120, used to obtain the angle signal generated by the combination switch module 120, and generate a control signal according to the angle signal; the communication chip 142 is communicatively connected to the main chip 141, used to obtain the control signal, and control the entire vehicle through the control signal.

[0048] It can be understood that in the embodiment of the present application, after the turning angle signal is generated, it is necessary to control the entire vehicle through the turning angle signal through the communication module 140, so the turning angle signal is converted into a control signal through the main chip 141, and the control signal is sent to the communication chip 142; the communication chip 142 can control the turning angle of the entire vehicle according to the control signal.

[0049] Through the communication module 140, the integrated turning angle sensor combination switch provided in the embodiment of the present application can realize the turning angle control of the vehicle according to the turning angle signal.

[0050] It should be noted that in the embodiment of the present application, the sensing device 122 and the correcting device 123 are 3D Hall sensors.

[0051] By using the 3D Hall sensor as the sensing device 122 and the correction device 123, the magnetic sensing unit 121 can perform high-precision magnetic sensing and accurately receive magnetic changes.

[0052] It should be noted that, in the embodiment of the present application, the combination switch module 120 is also used to realize multi-functional control of the vehicle, such as lighting control, wiper control, etc. of the vehicle.

[0053] On the other hand, the combined switch module 120 provided in the embodiment of the present application further includes: A light switch 125, the light switch 125 is used to control vehicle lights; The wiper switch 126 is used to control the vehicle wipers.

[0054] It should be noted that the light switch 125 in the embodiment of the present application is a light integrated switch, that is, the light switch 125 can be used to control the vehicle's turn signal lights and the on / off control of the headlights.

[0055] Exemplarily, in a feasible embodiment of the present application, the vehicle turn signal can be controlled by pressing the light switch 125 in a wave-like manner, and the vehicle headlights can be controlled by rotating the light switch 125 .

[0056] It is understandable that realizing vehicle lighting control through an integrated switch can enable the vehicle combination switch module to have a higher degree of integration.

[0057] The wiper switch 126 in the embodiment of the present application is used to control the wipers and washers of the vehicle.

[0058] Exemplarily, in a feasible embodiment of the present application, a wiper switch 126 can be set on the other side of the light switch 125, and the switch of the vehicle wiper can be controlled by rotation, and the operating frequency of the wiper can be selected by rotating the corresponding angle, and the washer can be controlled by pressing to spray cleaning fluid.

[0059] In the embodiment of the present application, the lighting control of the vehicle is realized by the light switch 125 provided by the combination switch module 120, and the wiper and washer control of the vehicle is realized by the wiper switch 126.

[0060] Based on the integrated angle sensing combination switch described above, an embodiment of the present application further provides a high-voltage interlock detection method, which is applied to the integrated angle combination switch, wherein the integrated angle combination switch comprises: a clock spring module, a combination switch module and a steering wheel, wherein the clock spring module comprises a stator and a rotor with a magnetic component, the combination switch module comprises a magnetic sensing unit, the combination switch is directly connected to the stator of the clock spring, and the steering wheel is connected to the rotor of the clock spring module.

[0061] Please refer to Figure 4 , is a flow chart of a control method of an integrated corner combination switch provided in an embodiment of the present application, such as Figure 4 As shown, the control method of the integrated corner combination switch provided in the embodiment of the present application may include but is not limited to step S401 and step S402: Step S401: obtaining the magnetic force change generated by the rotation of the rotor of the clock spring module driven by the steering wheel.

[0062] Step S402: Detect the magnetic force change caused by the rotation of the magnetic component on the rotor of the clock spring module through the magnetic sensing unit to generate a rotation angle signal.

[0063] The integrated turning angle sensing combination switch can realize magnetic induction to obtain the turning angle signal without the need to set up a separate turning angle sensing device, thereby reducing the cost of vehicle production.

[0064] It should be noted that in the embodiment of the present application, the magnetic sensing unit includes a sensing device, a correction device and a signal processing device; Please refer to Figure 5 , for the embodiment of this application Figure 4 The specific step diagram of step S402 is as follows: Figure 4 As shown, in the embodiment of the present application, step S402, detecting the magnetic force change caused by the rotation of the magnetic component on the rotor of the clock spring module through the magnetic sensing unit carried by the combination switch module, and generating an angle signal, may include but is not limited to steps S501 to S503: Step S501: Generate an initial rotation angle signal through a sensing device according to the change in magnetic force.

[0065] Step S502: Generate a correction signal through a correction device according to the change in magnetic force.

[0066] Step S503: Send the initial turning angle signal and the deviation correction signal to the signal processing device, and generate the turning angle signal through the signal processing device.

[0067] It should be noted that in the embodiment of the present application, the sensing device included in the magnetic sensing unit receives the magnetic force changes and can generate an initial angle signal. At this time, the correction device also receives the magnetic force changes and then generates a correction signal. The correction signal is used to compensate for the initial angle signal to make it more accurate. After the initial angle signal and the correction signal are obtained, the initial angle signal and the correction signal are sent to the signal processing device, and the angle signal can be generated by the signal processing device.

[0068] The embodiment of the present application provides a sensing device and a correcting device to receive magnetic force changes, so that the generated turning angle signal can be more accurate, thereby improving the accuracy of turning angle control.
