1. An occupant monitoring system (OMS) for monitoring at least one occupant in a vehicle, the vehicle having a steering wheel assembly configured to rotate relative to a steering column, the OMS comprising:an imaging unit coupled to a steering wheel assembly having a field of view inside of the vehicle configured to capture an image signal corresponding to an imaging area in the vehicle;
a processing unit including a processor and a memory operably coupled to the processor, the memory having computer-executable instructions stored thereon that, when executed by the processor, cause the processor to:
receive the image signal from the imaging unit;
analyze the image signal to determine an occupant state; and
output a signal based on the determined occupant state, where the output signal is outputted to another vehicle system to provide information about the occupant state to the other vehicle system, wherein the output signal includes instructions for at least one of the OMS and the other vehicle system to adjust a vehicle parameter based on the occupant state, and an adjusted vehicle parameter is used to warn the occupant;
wherein the adjusted vehicle parameter includes at least one of operation of a light source, operation of a cabin audio system, sensitivity of a steering wheel of the steering wheel assembly to user input, sensitivity of a braking system to user input, sensitivity of a vehicle accelerator to user input, operation of an interior light, a temperature of a vehicle cabin, a scent provided to an occupant cabin of the vehicle, output of a vehicle communication system, an operation of an autonomous driving state of the vehicle, and a tactile feedback to the occupant via a haptic feedback device; and
wherein the tactile feedback is provided to the steering wheel assembly and includes at least one of vibration, heat, and cooling effect.
