Claim 10:
11. A method for controlling operation of a transportation vehicle equipped with an automated driving function, the method comprising:
determining a first signal state of a traffic light from data generated by at least one transportation vehicle sensor and determining a second signal state of the traffic light from a Signal Phase and Timing (SPaT) message received from a communication infrastructure;
generating a validation result that validates the determined first signal state of the traffic light generated by the at least one transportation vehicle sensor by comparing the determined first signal state and the determined second signal state; and
setting an operation mode of the transportation vehicle as a function of the validation result, wherein the operation mode is set to:
a normal operation mode in response to the validation result indicating that the determined first signal state is valid because the generated first state matches the determined second signal state,
a safe mode in response to the validation result indicating that the determined first signal state generated by the at least one transportation vehicle sensor is not valid because the determined first signal state does not match the determined second signal state, and
a fallback mode in response to no first signal state being generated by the at least one transportation vehicle sensor thereby resulting in no validation result being determined.
