Description
Technical Field
The invention relates to the technical field of collision early warning, in particular to a vehicle collision early warning system and method based on a GPS.
Background
With the continuous progress of vehicle collision technology, the early warning of lane departure and early warning of rear-end collision of a target vehicle have good early warning effects. Once the target vehicle deviates from the driving lane or the target vehicle is too close to the front vehicle, an early warning system carried by the target vehicle can give an alarm for prompting, or the target vehicle actively brakes or automatically applies restoring force to a steering wheel, so that the target vehicle returns to the driving lane to normally drive. However, the existing vehicle-mounted collision early warning technology cannot perform early warning on the passing vehicle, and the occurrence of many accidents is usually caused by the fact that effective early warning and quick response cannot be performed on abnormal driving behaviors of the passing vehicle in time.
