[0043] The steering wheel is an important part of the car, through which the steering of the car can be controlled. In order to ensure safety, the driver generally needs to hold the steering wheel with both hands during driving. The patent CN108349519B discloses a vehicle steering wheel, the main feature of which is that a plurality of presence sensors are mounted on the same support, and at least one of the presence sensors is arranged opposite at least one portion of the joint of the outer sheath so as to define a detection area including at least one portion of the joint and extending on both sides of the at least one joint in the transverse direction of the at least one joint. The presence sensor arranged opposite the at least one portion of the joint has at least one edge that is always located on the same side of the joint. One detection area of the steering wheel can only correspond to one area on the rim, and it is difficult to detect the state of the driver holding the steering wheel

[0044] The inventor has designed a hand-off monitoring steering wheel through extensive and in-depth experiments.

[0045] More specifically, the solution adopted by the present application includes: detecting the approach or contact between the driver's limbs and the sensing area of the steering wheel by arranging a sensor pad and a plurality of sensing areas on the surface thereof, and covering at least a part of the handle with the sensor pad, so that at least one sensing area extends into different areas of the handle, thereby realizing detection of the state of the driver's hand holding the handle while effectively avoiding the steering wheel components.

[0046] The technical solutions provided by the embodiments of the present application are described below in conjunction with the drawings.

[0047] Embodiment 1

[0048] As shown in Figures 1-3 A hand-off monitoring steering wheel includes:

[0049] A handle 1, the handle 1 defines an inner area, an outer area, a front area and a back area along the surface thereof;

[0050] A sensor pad, comprising a plurality of sensing areas arranged on its surface, for detecting proximity and / or contact between the driver's limbs and the sensing areas of the steering wheel.

[0051] A control unit configured to detect a driver's limb pressing on the steering wheel that corresponds to a portion of one or more of the sensing areas;

[0052] The sensor pad covers at least a portion of the handlebar 1, such that at least one of the sensing areas simultaneously extends to the front, inner, and / or outer regions of the wheel hub, or at least one of the sensing areas simultaneously extends to the back, inner, and / or outer regions of the wheel hub.

[0053] The steering wheel rim 1 is divided into four regions along its surface: an inner region, an outer region, a front region, and a back region. The front region is the side of the steering wheel rim facing the driver; the back region is the side of the steering wheel rim facing away from the driver; the inner region is the side of the steering wheel rim facing the wheel hub; and the outer region is the side of the steering wheel rim facing away from the wheel hub. A sensor pad covers at least a portion of the steering wheel rim 1. The sensor pad detects whether the driver's limbs are in contact with the steering wheel, thereby detecting whether the driver is driving correctly. At least one sensor area covers two adjacent regions of the four areas of the steering wheel rim 1, such as the front region and the inner or outer region, or the back region and the inner or outer region, thus facilitating the detection of the driver's hand grip on the steering wheel rim 1. By placing the various sensor areas in different parts of the steering wheel rim, the numerous hand grip states can be detected with maximum accuracy.

[0054] like Figures 1-3 As shown, in some embodiments, the lower half of the steering wheel rim 1 is provided with a front groove 5, and the sensor pad includes a first sensing area 2. The first sensing area 2 is arranged in the back area of ​​the steering wheel rim 1 and the inner area of ​​the steering wheel rim 1 above the front groove 5. By opening the front groove 5 in the lower half of the steering wheel rim 1, the front groove 5 can be used to install decorative parts and / or steering wheel components. The sensor pad is set in the upper half of the steering wheel rim 1 and will not interfere with the groove. Moreover, the first sensing area 2 of the sensor pad is arranged in the back area and the inner area of ​​the steering wheel rim 1. When the driver holds the steering wheel correctly, his hand will contact the back area and the inner area of ​​the steering wheel rim 1, ensuring the detection effect of the driver's grip on the steering wheel rim 1.

[0055] It should be noted that the driver usually holds the steering wheel in the upper half of the handle rim 1, so the front groove 5 can be set in the lower half of the handle rim 1, and the sensor pad covers the upper half of the handle rim 1, which facilitates the detection of the driver's grip on the handle rim 1.

[0056] like Figures 1-3 As shown, in some embodiments, the first sensing area 2 further includes a front area arranged on the upper half of the handlebar 1 (since there is a certain overlap between the front area and the inner area, this part of the front area can also be understood as the area on the front that is biased towards the inside), extending from the back area to the front area via the 12 o'clock position of the handlebar 1. The first sensing area 2 includes a first part, a second part, and a connecting part for connecting the first part and the second part. When the sensor pad covers the handlebar 1, the first part is located in the back area of ​​the handlebar 1 and the inner area of ​​the handlebar 1 above the front groove 5, the second part is located in the front area of ​​the upper half of the handlebar 1, and the connecting part is located in the outer area of ​​the 12 o'clock position of the handlebar 1, so that the second part of the first sensing area 2 extends from the back area to the front area. This single sensing area spanning different areas of the handlebar can specifically detect the hand grip state of the driver in the usual way, while also effectively avoiding the arrangement of extended functional parts on the handlebar.

[0057] like Figures 1-3 As shown, in some embodiments, the sensor pad includes a spaced-apart second sensing region 3 and a third sensing region 4, wherein,

[0058] The second sensing area 3 is arranged in the outer left region of the upper half of the handlebar 1 and the lower left region of the handlebar 1 below the front groove 5 on the left half; the third sensing area 4 is arranged in the outer right region of the upper half of the handlebar 1 and the lower right region of the handlebar 1 below the front groove 5 on the right half. By setting the second sensing area 3 and the third sensing area 4, with the second sensing area 3 located in the outer left region of the handlebar 1 and the third sensing area 4 located in the outer right region of the handlebar 1, the left and right sides of the handlebar 1 are covered, so that the detection function can still be performed when the driver holds the handlebar 1 in the lower half region.

[0059] It should be noted that in this embodiment, the second sensing area 3 and the third sensing area 4 are symmetrically arranged, respectively distributed on the left and right halves of the handle ring 1. At any position on the handle ring, the first sensing area 2 and the second sensing area 3 or the third sensing area 4 are arranged in a flat pattern across the entire circumferential surface of the handle ring 1, so that there are no missed detection areas.

[0060] In some embodiments, the steering wheel further comprises two spokes 6 at 3 o'clock and 9 o'clock positions, part of the second sensing area 3 and the third sensing area 4 are arranged at the front surface area of the connection between the spokes 6 and the rim 1, and part of the first sensing area 2 is arranged at the back surface area of the connection between the spokes 6 and the rim 1. The spokes 6 are arranged at the 3 o'clock and 9 o'clock positions of the rim 1, the second sensing area 3 and the third sensing area 4 are at least partially wrapped around the front surface area of the connection between the spokes 6 and the rim 1, and the first sensing area 2 is at least partially wrapped around the back surface area of the connection between the spokes 6 and the rim 1. This arrangement facilitates the wiring of the sensor mat to be drawn out nearby, and extended through the spokes 6 to the power supply device and control unit in the hub.

[0061] The schematic diagram of the flat state of the sensor mat is shown in Figure 3 The schematic diagram of the flat state of the sensor mat is shown in

[0062] In some embodiments, a decorative element is installed in the front recess 5, which comprises one or more of a decorative ring, a light strip, and spliced leather. The decorative ring and the light strip can be used for decoration, and the spliced leather can be connected with the sensor mat to ensure the wrapping effect of the rim 1.

[0063] In some embodiments, the shape of the rim 1 comprises a circle, a U shape, a D shape, and a square. In this embodiment, the shape of the rim 1 is a circle, and in other embodiments, the shape of the rim 1 can also be one of a U shape, a D shape, and a square, which can be selected according to actual conditions.

[0064] Example 2

[0065] As shown in Figures 4-5As shown, Embodiment 2 discloses another hands-free monitoring steering wheel. The structure of Embodiment 2 is basically the same as that of Embodiment 1, except that the positions of the first sensing area 2, the second sensing area 3, and the third sensing area 4 of the sensor pad are different. In Embodiment 2, some of the second sensing areas 3 and 4 are arranged in the lower half of the front area of ​​the connection between the spoke 6 and the handle 1, and some of the first sensing areas 2 are arranged in the upper half of the front area of ​​the connection between the spoke 6 and the handle 1. The spokes 6 are arranged at the 3 o'clock and 9 o'clock positions of the handle 1. Some of the first sensing areas 2 cover the upper half of the front area of ​​the connection between the left and right spokes 6 and the handle 1, some of the second sensing areas 3 cover the lower half of the front area of ​​the connection between the left spoke 6 and the handle 1, and some of the third sensing areas 4 cover the lower half of the front area of ​​the connection between the right spoke 6 and the handle 1, thus achieving coverage of the connection between the spokes 6 and the handle 1.

[0066] Example 3

[0067] like Figures 6-7 As shown, Embodiment 3 discloses another hands-free monitoring steering wheel. Embodiment 3 has a basically the same structure as Embodiment 1, except that the positions of the first sensing area 2, the second sensing area 3, and the third sensing area 4 of the sensor pad are different. In Embodiment 3, the first sensing area 2 is arranged on the back of the steering wheel rim 1 and inside the lower half of the steering wheel rim 1; the second sensing area 3 is arranged on the front area of ​​the left side of the upper half of the steering wheel rim 1 and outside the steering wheel rim 1 below the front groove 5 on the left half; the third sensing area 4 is arranged on the front area of ​​the right side of the upper half of the steering wheel rim 1 and outside the steering wheel rim 1 below the front groove 5 on the right half. By setting a second sensing area 3 and a third sensing area 4, when the sensor pad covers the handlebar 1, the first sensing area 2 extends from the back area of ​​the upper half of the handlebar 1 to the inner area of ​​the lower half of the handlebar 1. The second sensing area 3 covers the front area of ​​the left side of the upper half of the handlebar 1 and the outer area of ​​the handlebar 1 below the front groove 5 of the left half. The third sensing area 4 covers the front area of ​​the right side of the upper half of the handlebar 1 and the outer area of ​​the handlebar 1 below the front groove 5 of the right half. This achieves the wrapping of the left and right sides of the handlebar 1, ensuring the sensor pad's detection effect on the driver's grip on the handlebar 1, while not affecting the front groove 5 of the handlebar 1.

[0068] Example 4

[0069] like Figures 8-9As shown, Embodiment 4 discloses another hands-free monitoring steering wheel. The structure of Embodiment 4 is basically the same as that of Embodiment 1, except that the positions of the first sensing area 2, the second sensing area 3, and the third sensing area 4 of the sensor pad are different. In Embodiment 4, the first sensing area 2 is arranged in the front area of ​​the upper half of the steering wheel 1 and the outer area of ​​the steering wheel 1 below the front groove 5. The second sensing area 3 is arranged in the left back area of ​​the upper half of the steering wheel 1 and the left inner area of ​​the lower half of the steering wheel 1. The third sensing area 4 is arranged in the right back area of ​​the upper half of the steering wheel 1 and the right inner area of ​​the lower half of the steering wheel 1. With this arrangement, the first sensing area 2, the second sensing area 3, and the third sensing area 4 can effectively avoid the front groove 5 without affecting the detection accuracy, so as not to affect the installation of decorative parts and / or components in the front groove 5.

[0070] Example 5

[0071] like Figures 10-11 As shown, Embodiment 5 discloses another hands-free monitoring steering wheel. The structure of Embodiment 5 is basically the same as that of Embodiment 1, except that the groove on the steering wheel 1 is formed in a different way and the positions of the first sensing area 2, the second sensing area 3 and the third sensing area 4 of the sensor pad are different. The front area of ​​the steering wheel 1 is provided with a front annular groove 7. The first sensing area 2 is at least partially arranged in the inner area, and the second sensing area 3 and the third sensing area 4 are at least partially arranged in the outer area. The annular groove on the front area of ​​the steering wheel 1 makes the first sensing area 2 at least partially arranged in the inner area and the second sensing area 3 and the third sensing area 4 at least partially arranged in the outer area. The connection between the first sensing area 2 and the second sensing area 3 and the third sensing area 4 passes through the back area of ​​the steering wheel 1.

[0072] It should be noted that, in this embodiment, the second sensing area 3 is at least partially arranged in the outer left region of the handlebar 1, and the third sensing area 4 is at least partially arranged in the outer right region of the handlebar 1. The second sensing area 3 and the third sensing area 4 are symmetrically distributed about the center of the handlebar.

[0073] In other embodiments, the back area of ​​the handle 1 is provided with a back annular groove, the first sensing area 2 is at least partially arranged in the outer area, and the second sensing area 3 and the third sensing area 4 are at least partially arranged in the inner area. In this case, the connection between the first sensing area 2 and the second sensing area 3 and the third sensing area 4 passes through the front area of ​​the handle 1.

[0074] It should be noted that when the annular groove is made on the handle ring 1, the front annular groove 7 can be made on the front area of ​​the handle ring 1, or the back annular groove can be made on the back area of ​​the handle ring 1, depending on the use requirements.

[0075] Embodiment 6

[0076] As shown in Figures 12-13 Embodiment 6 discloses another hand-off monitoring steering wheel, which is basically the same as that of Embodiment 1, except that the way of opening the groove on the grip 1 and the positions of the first, second and third sensing areas 2, 3 and 4 of the sensor pad are different, the front surface area of the grip 1 is provided with a front surface annular groove 7, the first sensing area 2 is arranged at least partially in the outer area, the second and third sensing areas 3 and 4 are arranged at least partially in the inner area, the second sensing area 3 is arranged at least partially in the left inner area of the grip 1, and the third sensing area 4 is arranged at least partially in the right inner area of the grip 1.

[0077] Each embodiment in the specification can be referred to each other for the same or similar parts, and each embodiment focuses on the difference from other embodiments. Especially, for the method embodiment described later, since it is corresponding to the system, the description is relatively simple, and the relevant part can be referred to the part of the system embodiment.

[0078] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
