Vehicular health monitoring system and method

Abstract

A vehicle includes a control system for controlling one or more operations of the vehicle. A touchpoint integrated in the vehicle is configured to receive PPG signals reflected from skin of an occupant, wherein the PPG signals are at a plurality of wavelengths. A processing circuit is configured to determine a signal quality of at least one of the PPG signals and generate one or more of: a visible feedback, an audible feedback or a tactile feedback in response the signal quality of the at least one PPG signal. The PPG signals to obtain health information of a user and generate a health message to the control system of the vehicle in response to the health information, wherein the control system controls one or more operations of the vehicle in response to the health message.

What is claimed is: 
     
         1 . An apparatus comprising:
 a vehicle control button including a biosensor, the biosensor comprising:
 a transceiver configured to communicate with a vehicle; 
 a PPG circuit configured to detect light at a touchpoint that is reflected from skin of a finger of an occupant of the vehicle and to generate a first photoplethysmography (PPG) signal, wherein the light includes at least a first wavelength; and 
 a processing circuit, configured to:
 process the first PPG signal to determine a signal quality of the first PPG signal; 
 generate first feedback to the occupant of the vehicle that includes one or more of: a visible feedback, an audible feedback or a tactile feedback in response to the signal quality of the first PPG signal, wherein the feedback includes a request for an adjustment of a position of the finger with respect to the touchpoint; 
 obtain health information of the occupant using the first PPG signal, wherein the health information includes a heart rate; and 
 generate a health message to the vehicle or the occupant of the vehicle including the health information.
