1. A collision warning system of a motor vehicle having a windshield, the collision warning system notifying an occupant of the motor vehicle about a predicted collision between the motor vehicle and an object that is positioned external to the motor vehicle and moving relative to the motor vehicle, the collision warning system comprising:
at least one object input device for generating an object signal associated with movement of the object relative to the motor vehicle, wherein the at least one object sensor is fixed to the vehicle and is selected from a group consisting of a camera and a radar device;
at least one vehicle input device for generating a vehicle signal associated with movement of the motor vehicle;
a road detection module for generating a road signal associated with a road geometry that is visible through the windshield and located within a field of view of the occupant, with the object moving toward a crash site portion of the road geometry;
an Augmented Reality Head Up Display module (ARHUD) for generating a plurality of images upon the windshield and overlaid onto the road geometry; and
a computer including at least one processor electrically communicating with the at least one object input device, the at least one vehicle input device, the road detection module, and the ARHUD, where the computer further includes a non-transitory computer readable storage medium storing instructions such that the at least one processor is programmed to:
receive the object signal from the at least one object input device, the vehicle signal from the at least one vehicle input device, and the road signal from the road detection module;
determine a predicted collision between the object and the motor vehicle at the predicted crash site portion of the road geometry at a predicted time based on the object signal, the vehicle signal, and the road signal; and
generate an actuation signal in response to the at least one processor determining the predicted collision; and
wherein the ARHUD is configured to generate the plurality of images upon the windshield and overlaid onto the road geometry to notify the occupant of the predicted collision in response to the ARHUD receiving the actuation signal from the at least one processor, and wherein the ARHUD is configured to generate the plurality of images upon the windshield at a first predetermined amount of time before the predicted time of the predicted collision when the processor determines that a current braking distance of the motor vehicle is more than a current distance between the motor vehicle and the predicted crash site portion, and the ARHUD is configured to generate the plurality of images upon the windshield at a second predetermined amount of time, that is after the first predetermined amount of time and before the predicted time of the predicted collision, when the processor determines that the current braking distance of the motor vehicle is determined to be more than the current distance between the motor vehicle and the predicted crash site portion, and wherein the plurality of images upon the windshield generated at the second predetermined amount of time is greater than the first predetermined amount of time provided to avoid false alarms.
