Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 2, a steering wheel detecting module includes a steering wheel frame S14, a foamed layer S13 disposed outside the steering wheel frame S14, a detecting layer S12 disposed outside the foamed layer S13, a leather layer S11 disposed outside the detecting layer S12, and a steering wheel controller; the detection layer S12 is a whole or separated into two or more sensing areas, and when the detection layer S12 is separated into two or more sensing areas, each sensing area can detect whether the driver' S hand is on the steering wheel; the detection layer S12 is electrically connected to a steering wheel controller.
As shown in fig. 2, in the present embodiment, the steering wheel skeleton S14 serves as a frame carrier S124 of the entire steering wheel, the foam layer S13 is used to enhance softness of hand feeling, and the leather layer S11 is used to enhance appearance quality.
In this embodiment, the detection layer S12 includes a carrier S124, a shielding layer S123, an isolation layer S122, and a sensing layer S121 that are sequentially disposed from inside to outside, and the sensing layer S121 is separated into a plurality of pieces, each of which is a sensing region. The carrier S124 is coated with glue for easy attachment to the foam layer S13, and in order to reduce the overall odor, a less odorous aqueous glue is used here. The shielding layer S123 is arranged on the carrier S124 and used for shielding electromagnetic interference on the steering wheel framework S14, reducing detection errors and improving safety level. The isolation layer S122 is disposed between the shielding layer S123 and the sensing layer S121, so as to avoid direct contact between the two layers of metal.
In this embodiment, the sensing layer S121 is generally divided into a plurality of regions according to the requirement and the determination accuracy, and the more the divided regions are, the more the detection accuracy and the position of the detection determination hand on the steering wheel are accurate.
As shown in fig. 3, the sensing layer S121 is an integral schematic diagram.
As shown in fig. 4, the sensing layer S121 is separated into two regions, an upper one corresponding to an upper portion of the steering wheel and a lower one corresponding to a lower portion of the steering wheel.
Fig. 5 is a schematic diagram in which the sensing layer S121 is divided into three regions, an upper left block corresponding to an upper left portion of the steering wheel, an upper right block corresponding to an upper right portion of the steering wheel, and a lower block corresponding to a lower portion of the steering wheel.
In the following description, taking an example in which the sensing layer S121 is divided into three, the upper left portion of the steering wheel is defined as a first sensing region, the upper right portion of the steering wheel is defined as a second sensing region, and the lower portion of the steering wheel is defined as a third sensing region. When the hand of the driver touches the first sensing area of the steering wheel, the first sensing area outputs high level, otherwise, the first sensing area outputs low level. When the steering wheel controller receives the current signal 000 output from the sensing layer S121, it means that the driver' S hand is off the steering wheel. When the steering wheel controller recognizes the current signal of 001, if the current signal data sequentially represents the states of the third sensing area, the second sensing area and the first sensing area from left to right, 001 represents that the driver has a half-hand grip or only touches the first sensing area of the steering wheel. When the steering wheel controller recognizes a 011 current signal, it means that the driver's hands respectively hold or touch the first and second sensing regions of the steering wheel. When the steering wheel controller recognizes 111 the current signal, it means that the driver's hands respectively hold the first sensing area, the second sensing area and the third sensing area of the steering wheel. According to the logic definition, the real-time state of the two hands of the driver can be judged based on the current signals received in real time.
As shown in fig. 1, in this embodiment, a system for detecting a driver takeover capability includes:
the steering wheel detection module 1 is used for detecting the states of both hands of a driver, and the steering wheel detection module 1 adopts the steering wheel detection module as described in the embodiment;
the driving environment recognition module 3 is used for detecting the surrounding environment parameters of the vehicle;
when the driving environment recognition module 3 outputs a signal to judge that the driver needs to take over, the driving control module 2 acquires the signal output by the detection layer S12 to judge whether the driver has the taking over capability, and the driving control module 2 is respectively electrically connected with the driving environment recognition module 3 and the steering wheel controller;
and the alarm module 5, the alarm module 5 is electrically connected with the driving control module 2.
In this embodiment, the driving control module 2 is connected to the execution module 4, and the execution module 4 includes a brake, a clutch, and a steering device.
In this embodiment, driving environment recognition module 3 includes front car radar, back car radar, side radar and camera.
In this embodiment, the alarm module is a buzzer for prompting the driver to take over.
As shown in fig. 6, the specific execution flow of the system is as follows:
the system starts from step S21, step S21 represents that the vehicle is started successfully, at this time, the sensing layer S121 on the steering wheel is powered on, the sensing layer S121 receives an external signal (i.e., step S22), and sends out a corresponding current signal regardless of whether the hand is separated from, touched with, or gripped with the steering wheel, and the current signal is converted into a LIN signal in step S24, and the LIN signal is forwarded to the CAN line through the gateway (i.e., step S25). In step S26, the vehicle operation control module 2 may receive the relevant signals of the CAN line, where the relevant signals include, from step S27, the vehicle operation environment identified by the vehicle radar and the camera (step S28), and the identified environment signals transmitted to the CAN line (step S29), where the environment signals specifically include the distance to the adjacent vehicle, the route prediction of the vehicle ahead, the information of the peripheral object, and the like.
In step S30, the vehicle determines whether the vehicle needs to take over by the driver according to the function request at this time, and if the automatic driving function of the vehicle is not turned on, it is determined that the vehicle does not need to take over by the driver, and the frame signal flow is ended (i.e., step S31). When it is determined that the driver needs to take over, it is determined whether the driver has the capability of taking over (i.e., step S32), at this time, the signal of the steering wheel detection module 1 is extracted, and it is determined whether the driver has the capability of taking over according to the logic of the driving control module 2. If the capability of taking over is detected, the vehicle exits the automatic driving state and is driven by the driver (i.e., step S33), and the process ends (i.e., step S34). If no take-over capability is detected, the vehicle reminds the driver through the honey device (namely step S35), meanwhile, the step S26 is returned, next frame signals on the CAN line are extracted, the steps S30 and S32 are repeated, and judgment is carried out again.
In step S36, during the period Ts, it is always detected that the driver has no capability of taking over, and the system will execute the action of forced parking, including in-place parking or parking beside, where the specific parking mode is determined according to the ambient environment signal detected by the vehicle ECU 4. And in the period Ts, detecting that the driver has the capability of taking over, and controlling the driving by the driver after the vehicle exits from the automatic driving state. Each frame of signal reaches the purpose of controlling the whole vehicle through the judgment of the flow. Through the logic flow, whether the driver has the takeover capability or not can be detected according to the design requirements, and the judgment that the driver is taken over to continue driving or is not taken over to forcibly stop is made, so that accidents caused by the fact that the driver cannot take over are avoided.
In this embodiment, a vehicle employs the driver takeover capability detection system as described in this embodiment.
