1. A system for reducing thermal induced error in real-time for a sensor in a region of interest of a vehicle, the system comprising:
a sensor of interest having a thermal sensitivity and an offset shift for a given temperature range;
a temperature sensor, the temperature sensor configured to determine a temperature for the sensor of interest;
a memory; and
a processor coupled to the memory, wherein the processor is configured to execute instructions to:
calculate real-time sensor thermal error reduction data;
wherein the processor is configured to use midpoint temperature error reduction to calculate the real-time sensor thermal error reduction, the processor configured to execute instructions to:
determine multiple percentage change coefficients for the thermal sensitivity;
determine multiple percentage change coefficients for thermal zero offset;
within a temperature reading range determined by the temperature sensor, curve-fit more than one polynomial function using regression analysis;
determine at least two boundary regions; and
select a boundary condition to reduce sensor thermal error using at least one of the thermal sensitivity percentage change coefficients and at least one of the thermal zero offset percentage change coefficients.
