[0054] The following describes exemplary embodiments of the present disclosure with reference to the accompanying drawings. Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, descriptions of well-known functions and structures are omitted below for clarity and conciseness.
[0055] The following describes a method and device for prompting the driver to release the steering wheel, a vehicle, and an electronic device according to embodiments of the present disclosure with reference to the drawings.
[0056] Figure 1 Schematic flow chart of a method for prompting the driver to release the steering wheel provided by an embodiment of the present disclosure.
[0057] As Figure 1 shown, the method includes the following steps:
[0058] Step 101, detect whether there is human hand contact on the steering wheel and obtain a detection signal.
[0059] The present disclosure can be applied to any type of vehicle such as a sedan or an off-road vehicle. Specifically, the type of the vehicle is not limited in the embodiments of the present disclosure.
[0060] In the embodiments of the present disclosure, the method for detecting whether there is human hand contact on the steering wheel includes, but is not limited to, torque sensing, grip sensing, and capacitance sensing, etc. Specifically, the method for detecting whether there is human hand contact on the steering wheel can be determined according to the actual situation, and the embodiments of the present disclosure do not limit it.
[0061] Among them, for capacitive sensing, it senses the capacitance change when a human hand touches and leaves the steering wheel through the capacitive sensing layer on the steering wheel rim, converts it into an electrical signal, and sends it to the in-vehicle system. The in-vehicle system determines whether there is a human hand touching the steering wheel based on the electrical signal. For torque sensing, it determines whether there is a human hand touching the steering wheel by detecting the control state of the steering wheel. When using the assisted driving function with a torque steering wheel, the driver's hand needs to slightly turn the steering wheel for the system to sense that the hand has not left the steering wheel. For grip force sensing, a small ECU, a sensor pad, and an alternating voltage are applied to the induction protection electrode are integrated on the steering wheel. Simply put, when the driver holds the steering wheel and applies sufficient pressure to the steering wheel, the steering wheel will detect that the driver's hand has not left the steering wheel. If the driver's grip on the steering wheel is not strong enough, the voltage may be in an off state, and the system will detect that the driver's hand is in a detached state. At the same time, when detecting whether there is a human hand touching the steering wheel, a detection signal will be generated, and it can be determined whether there is a human hand touching the steering wheel through the detection signal.
[0062] Step 102, if the detection signal indicates that there is no human hand touching the steering wheel, generate a corresponding hand-off signal.
[0063] In the embodiment of the present disclosure, the hand-off signal is an electrical signal generated by the hand-off detection module on the steering wheel when it detects that the driver's hands leave the steering wheel. For example: if a high-level electrical signal is generated when it detects that the driver's hands leave the steering wheel, then this high-level electrical signal is the hand-off signal; if a low-level electrical signal is generated when it detects that the driver touches the steering wheel, then this low-level electrical signal is the contact signal.
[0064] Step 103, control the preset component to send a prompt signal according to the preset prompt rule corresponding to the hand-off signal, and the prompt signal includes a lighting signal, a sound signal, and / or a vibration signal.
[0065] In the embodiment of the present disclosure, the methods of giving prompts include but are not limited to: giving a lighting prompt through a preset atmosphere light, playing a preset prompt message through a preset voice device for a voice prompt, turning on vibration through a preset vibration device for a vibration prompt, etc. The preset components include but are not limited to: a preset atmosphere light, a preset voice device, a preset vibration device, etc. Specifically, the present disclosure embodiment does not limit the methods of giving prompts and the preset components.
[0066] The prompt signal is a signal for controlling the vehicle to give a prompt. For example: a signal for controlling a preset ambient light, a signal for controlling a preset voice device, a signal for controlling a preset vibration device, etc. When the vehicle machine detects the presence of a hand-off signal, the vehicle machine will automatically generate a prompt signal. Among them, when giving a lighting prompt through a preset ambient light, the preset ambient light is a custom ambient light arranged around the steering wheel buttons. The preset prompt rule is a custom-set rule. For example: the ambient light displays different colors to prompt the driver of the status of the steering wheel takeover, the ambient light flashes to prompt the driver that the steering wheel needs to be taken over, etc. Specifically, the type of the preset ambient light and the content of the preset prompt rule are not limited in the embodiments of the present disclosure.
[0067] It should be noted here that in the steering wheel button module of the steering wheel, an ambient light control chip is integrated. The ambient light control chip is used to control the preset ambient light to give a lighting prompt according to the preset prompt rule based on the hand-off signal. To facilitate understanding of the positional relationship of the preset ambient light, as Figure 2 shown, Figure 2 is a schematic diagram of a steering wheel setting provided by the present disclosure. Among them, 21 is the steering wheel button module, and 22 is the preset ambient light.
[0068] The method for prompting the hand-off of the steering wheel provided by the present disclosure detects whether there is human hand contact on the steering wheel and obtains a detection signal; if the detection signal indicates that there is no human hand contact on the steering wheel, a corresponding hand-off signal is generated; a preset component is controlled to send a prompt signal according to a preset prompt rule corresponding to the hand-off signal, and the prompt signal includes a lighting signal, a sound signal, and / or a vibration signal. Compared with the related art, in the embodiments of the present disclosure, by controlling the preset components in the vehicle to give a prompt for the hand-off state of the steering wheel according to the lighting signal, sound signal, and / or vibration signal included in the prompt signal, the prompt effect is better than the text prompt, which can enable the driver to more intuitively notice the hand-off state information of the steering wheel, take over the steering wheel in time, and improve driving safety.
[0069] In a realizable manner of the embodiments of the present disclosure, as a refinement of the above step 103, when giving a prompt, it is necessary to clearly distinguish the state of the driver's takeover of the steering wheel so that the driver can more intuitively notice the hand-off state information of the steering wheel. At this time, a prompt can be given through a preset ambient light. Therefore, in order to clearly prompt the driver, the following methods can be used but are not limited to: obtaining the duration corresponding to the hand-off signal; if the duration is less than or equal to a preset duration threshold, controlling the preset ambient light to give a lighting prompt through a first preset prompt method; if the duration is greater than the preset duration threshold, controlling the preset ambient light to give a lighting prompt through a second preset prompt method.
[0070] In an embodiment of the present disclosure, when the preset ambient light gives a lighting prompt, it includes but is not limited to: giving a prompt through a corresponding light source array. The preset duration threshold is a duration set by the user, for example: 10 seconds, 15 seconds, 20 seconds, etc.; the first preset prompt method is a prompt method set by the user to prompt that the driver's hands have left the steering wheel, for example: prompting by displaying the preset ambient light in yellow, prompting by displaying the preset ambient light in green, etc.; the second preset prompt method is also a prompt method set by the user to prompt that the driver needs to take over the steering wheel, for example: prompting by gradually changing the preset ambient light from yellow to red, prompting by flashing the preset ambient light in red, etc. Specifically, the present disclosure embodiment does not limit the preset duration threshold, the first preset prompt method, and the second preset prompt method.
[0071] In an implementable manner of an embodiment of the present disclosure, when detecting whether there is human hand contact on the steering wheel, there are two situations. Situation 1: It is determined that there is no human hand contact on the steering wheel. Situation 2: It is determined that there is human hand contact on the steering wheel. Regarding Situation 1, it has been described in the above steps. Next, the description related to Situation 2 needs to be carried out. Since when there is human hand contact on the steering wheel, it is also necessary to give a prompt to the driver to distinguish it from the situation where there is no human hand contact on the steering wheel. At this time, only a prompt needs to be given through the preset ambient light. Therefore, after detecting whether there is human hand contact on the steering wheel, the following methods can be adopted but are not limited to: If the detection signal indicates that there is human hand contact on the steering wheel, control the preset ambient light to give a lighting prompt through a third preset prompt method.
[0072] In an embodiment of the present disclosure, when the detection signal indicates that there is human hand contact on the steering wheel, a contact signal will be generated. The contact signal is an electrical signal generated by the off-hand detection module on the steering wheel when detecting that the driver touches the steering wheel. For example: If it is detected that the driver's hands leave the steering wheel, a high-level electrical signal is generated, and this high-level electrical signal is the off-hand signal; if it is detected that the driver touches the steering wheel, a low-level electrical signal is generated, and this low-level electrical signal is the contact signal.
[0073] Among them, the third preset prompt method is a prompt method set by the user to prompt that the driver has touched the steering wheel, for example: prompting by displaying the preset ambient light in white, prompting by displaying the preset ambient light in blue, turning off the preset ambient light, etc. Specifically, the present disclosure embodiment does not limit the third preset prompt method.
[0074] In an implementable manner of the embodiments of the present disclosure, when prompting the driver to take over the steering wheel, in order to achieve a better prompting effect and enable the driver to realize the need to take over the steering wheel more quickly, the following methods may be adopted but are not limited to: controlling the preset voice device to play a preset prompt message corresponding to the hand-off signal for voice prompting; and / or, controlling the preset vibration device to vibrate with an intensity corresponding to the hand-off signal for vibration prompting. Wherein, the preset prompt message is custom-set information, for example: Please take over the steering wheel, Please note to take over, etc. Specifically, the embodiments of the present disclosure do not limit the preset prompt message.
[0075] It should be noted that only when the duration of the hand-off signal is greater than the preset duration threshold, voice prompting and / or vibration prompting will be performed. In the case where a person's hand touches the steering wheel or the duration of the hand-off signal is less than or equal to the preset duration threshold, only prompting through the preset atmosphere light is required.
[0076] In an implementable manner of the embodiments of the present disclosure, when detecting whether there is a person's hand touching the steering wheel, the existing main hand-off detection technology is to sense the capacitance change when a person's hand touches and leaves the steering wheel through the capacitance induction layer on the steering wheel rim, and convert it into an electrical signal. Therefore, in order to accurately detect whether there is a person's hand touching the steering wheel, the following methods may be adopted but are not limited to: obtaining the capacitance value of the capacitance induction layer on the steering wheel, where the capacitance induction layer is used to sense the capacitance change when a person's hand touches the steering wheel and when a person's hand leaves the steering wheel; if the capacitance value is greater than or equal to a preset capacitance threshold, it is determined that there is a person's hand touching the steering wheel; if the capacitance value is less than the preset capacitance threshold, it is determined that there is no person's hand touching the steering wheel. Wherein, the preset capacitance threshold is a threshold set by customization, for example: 1F, 2F, etc. Specifically, the embodiments of the present disclosure do not limit the preset capacitance threshold.
[0077] In an implementable manner of the embodiments of the present disclosure, since a preset atmosphere light will give a prompt regardless of whether there is human hand contact on the steering wheel, when the preset atmosphere light gives a prompt, a corresponding signal will be generated whether there is human hand contact on the steering wheel or not, and the signal will be transmitted to the steering wheel button module to control the preset atmosphere light to give a lighting prompt. In order to complete the control of the preset atmosphere light, the following methods can be used but are not limited to: the preset detection module sends the hand-off signal or the contact signal to the preset vehicle machine control module according to the preset communication protocol; the preset vehicle machine control module sends the hand-off signal or the contact signal to the preset steering wheel button module according to the preset communication protocol; the preset steering wheel button module controls the preset atmosphere light to give a lighting prompt according to the preset prompt rule based on the hand-off signal through a preset atmosphere light control chip; or, the preset steering wheel button module controls the preset atmosphere light to give a lighting prompt through a third preset prompt method based on the contact signal through the preset atmosphere light control chip. By integrating the atmosphere light control chip into the steering wheel button module in the embodiments of the present disclosure, the cost is reduced. Among them, the preset communication protocol is a communication protocol selected customarily, for example: LIN communication protocol, CAN bus communication protocol, etc.; the atmosphere light control chip is a chip selected customarily, for example: FM33LE0A series low-power MCU chips, etc. Specifically, the embodiments of the present disclosure do not limit this.
[0078] In summary, the embodiments of the present disclosure can achieve the following effects:
[0079] 1. By controlling the preset components in the vehicle to give a prompt of the hand-off state of the steering wheel according to the lighting signal, sound signal, and / or vibration signal included in the prompt signal, the embodiments of the present disclosure have a better prompt effect than text prompts, enabling the driver to more intuitively notice the hand-off state information of the steering wheel, take over the steering wheel in time, and improve driving safety.
[0080] 2. By integrating the atmosphere light control chip into the steering wheel button module, the embodiments of the present disclosure reduce the cost.
