INTELLIGENT VEHICLE SYSTEMS AND CONTROL LOGIC FOR MITIGATING SENSOR LIMITATIONS ON MIXED GRADIENT PATHS

Presented are intelligent vehicle systems providing AV/ADAS driving features with enhanced on-vehicle sensor operation for mixed-gradient pathways, methods for making/using such systems, and vehicles equipped with such systems. A method of operating a host vehicle includes a vehicle controller receiving gradient data indicating the host vehicle is traversing a mixed-gradient pathway. After receiving the gradient data, first and second on-vehicle sensors detect a target vehicle forward of the host vehicle on the mixed-gradient pathway. After detecting the target, the vehicle controller determines whether or not both sensors dropped the target vehicle. Responsive to the target vehicle being dropped, the vehicle controller determines if the target vehicle is reacquired by only the first sensor and not the second sensor. If so, the vehicle controller responsively transmits one or more command signals to one or more resident subsystems of the host vehicle to suppress an automated driving operation of the host vehicle.
