Communicating a blending control parameter using a seat of a vehicle

A vehicle comprising:

• a driver's seat;
• and
• one or more processors including machine executable instructions in non-transitory memory to cause the vehicle to:
• determine a blending parameter for a driving task for a vehicle, the blending parameter representing a ratio between a driver's level of authority and the one or more processor's level of authority in performing the driving task;
• correlate the blending parameter to a target sensory perception value to be perceived by the driver through the driver's seat;
• use a psychophysical model which correlates physical stimuli to sensory perception via a non-linear relationship to determine a physical stimulus value to produce the target sensory perception value, wherein the psychophysical model considers at least one of:
• ambient temperature and humidity in the cabin of the vehicle;
• current temperature of upholstery material of the driver's seat;
• the upholstery material of the driver's seat;
• skin temperature characteristics;
• location of an applied temperature vis-a-vie the driver's body;
• or
• stored calibration data related to the driver's perception of physical temperature changes;
• and
• generate the physical stimulus value at the driver's seat thereby communicating to the driver the ADS's level of authority in performing the driving task.
