System and method for operating autonomous cruise control in lowered traction and visibility mode

Abstract

An autonomous cruise control (ACC) system that implements a corrective action strategy based on driving conditions for a vehicle is provided. The ACC system includes a drive unit, vehicle sensors and a controller. The controller: receives at least signal from at least one vehicle sensor indicative of a driving condition; determines, based on the signal, whether the at least one signal satisfies a threshold indicative of an unsafe driving condition; and performs the corrective action strategy based on the determination that at least one signal satisfies an unsafe driving condition. The corrective action strategy comprises at least one of: (i) increasing a preset distance to a target vehicle; (ii) communicating a message to a human machine interface indicative of an unsafe driving condition; (iii) communicating a signal to vehicle brakes to initiate a braking event; and (iv) communicating a signal to a traction control system to alter an acceleration setting.
