1. A vehicle control system for at least partially automatically controlling a host vehicle, the vehicle control system comprising:

  • a vehicle controller, resident on the host vehicle, configured to determine automated vehicle control commands for at least partially automatically controlling the host vehicle based at least in part on sensor information, the automated vehicle control commands each being arranged to be directly or indirectly utilized by one or more host vehicle control units resident on the host vehicle to facilitate implementation of such automated vehicle control commands; and

    one or more safety monitoring algorithms executed separately from the vehicle controller that, during at least partially automated driving, verify that selected automated vehicle control commands received from the vehicle controller meet selected safety criteria, wherein at least some of the one or more safety monitoring algorithms utilize sensor information in the verification of the automated vehicle control commands received from the vehicle controller, wherein neither the safety algorithms, nor outputs from the safety algorithms are used in the determination of the automated vehicle control commands by the vehicle controller, and wherein the verified vehicle control commands are utilized by the one or more host vehicle control units to facilitate implementation of the automated vehicle control commands.
