Most of the existed distance detection systems switch between different modes such as high speed and low speed. In fact, the safety distance between vehicles is related to the speed and weather conditions. This patent is a way to automatically adjust the safety distance with factors such as speed and weather conditions. And it can greatly improve the safety factor of driving.

The safety distance will be automatically adjusted with the speed and weather conditions. The faster the speed or the poor weather conditions, the longer the safety distance is.
The safety distance will be automatically adjusted with the road slope. The safety distance of the downhill road will be automatically extended.
With the front distance detection system, the vehicle can be alerted when the safety distance is insufficient, to remind the driver to decelerate properly to avoid the occurrence of chasing.
If the system is mounted with the automatic brake assisting system, the brake deceleration can be automatically started in the case of insufficient safety distance to improve the road safety.
With the rear distance detection system, in the case of insufficient safety distance of the rear vehicle, the driver should promptly accelerate or change the lane to avoid collision in the case of inconspicuous driving.
The technology can also be applied to the automatic following system, which can keep the distance of vehicles in a safe region to improve the driver＇s acceptance of the following system.
In addition to being integrated into the safety design of a new car to improve the safety factor of the vehicle, the technology can also be used for retrofitting old vehicles as a driving safety facility.
This technology is applicable to the automobile manufacturing industry and the automobile maintenance industry. The installation on the vehicle can greatly improve the driving safety factor.
The technology can also be applied to locomotives or various types of moving vehicles to improve the safety factor of the vehicle.
