The steering wheel body has a first region and a second region which are relatively independent. The first region is entirely or partially covered by the first conductive flexible member 11. The second region is entirely or partially covered by the second conductive flexible member 13. In the process of the driver operating the automobile steering wheel, the first conductive flexible member 11 and the second conductive flexible member 13 are respectively used to contact the left hand and the right hand of the driver.

Specifically, the control member 15 can adopt a single PIN pin for power supply and ground inside the steering wheel. The control member 15 can adopt a single PIN pin for LIN communication interface inside the steering wheel. The control member 15 can adopt a single row of 4 PIN pins for the signal analog input interface of the first conductive flexible member 11 and the second conductive flexible member 13 (which can also include a third conductive flexible member 14 below).

The MCU (Micro Control Unit) burning interface of the circuit board adopts double-row 10PIN pins.
[0041] Specifically, in the process of monitoring the electrocardiogram, the first conductive flexible member 11 and the second conductive flexible member 13 of the automobile steering wheel are electrically connected, and the data collected by the left hand and the right hand of the driver are transmitted to the first detection unit (such as the front-end acquisition module and the A / D conversion function) of the control member 15 and the driver health monitoring ECU, and the data are transmitted to the data demander (such as the driver or other personnel) through communication and management.
[0042] The automobile steering wheel provided by the embodiment of the utility model further includes a third conductive flexible member 14 which is electrically connected with the control member 15, and the steering wheel body further includes a third region which is independently arranged with the first region and the second region, and the third region entirely or partially covers the third conductive flexible member 14; in the process that the driver operates the automobile steering wheel, the single hand of the driver simultaneously contacts the third conductive flexible member 14 and the first conductive flexible member 11 and / or the single hand of the driver simultaneously contacts the third conductive flexible member 14 and the second conductive flexible member 13; and the control member 15 further has a second detection unit which is used for off-hand detection.
[0043] Through the above setting, the second detection unit can collect the impedance value of each region, and the off-hand state of each region of the steering wheel is further obtained by comparison with the calibration value. That is, through the above setting, the demand of the HOD (Hands On Detection) function can be met, so as to facilitate off-hand detection, and the driving safety is further improved.
[0044] Specifically, the three independent conductive flexible members (the first conductive flexible member 11, the second conductive flexible member 13 and the third conductive flexible member 14) are electrically connected with the control member 15 (such as the additional acquisition channel of the front-end acquisition module of the control member 15) through wires, the control member 15 converts analog data into digital signals and sends to the driver health monitoring ECU, the library file of the ECU is calculated by the received digital voltage data and the hardware preset value (input end capacitor and resistor) to obtain the input impedance of the analog input port, the impedance value is sent or the impedance value and the calibration value are compared to directly output the off-hand state code of each region, and the demand requester can know the off-hand state of the driver in the region according to the impedance value and the off-hand state code.

The first conductive flexible element 11 and the second conductive flexible element 13 are respectively connected to the control element 15 (such as the front-end acquisition module) via wires. The control element 15 (such as the front-end acquisition module) collects analog voltage data from the left and right hands, converts it into digital signals, and sends them to the driver health monitoring ECU.

[0059] The integrated structure can be a split combination structure realized by separate processing and fixed connection, or an overall structure realized by common processing through a processing process.
