The invention discloses an automatic vehicle call-for-help method. The automatic vehicle call-for-help method comprises the following steps of: transmitting call-for-help information to a surrounding vehicle when the vehicle has an accident and is required to call for help, and waiting for the surrounding vehicle to response; transmitting information to a command center if the rescue response information of the surrounding vehicle is detected, notifying that the command center receives the rescue from the surrounding vehicle and forwarding the rescue response information of the rescue vehicle to the command center, so that the command center can track the real-time position of the rescue vehicle in real time, and rescue workers and vehicles are timely organized to meet with the rescue vehicle; and automatically transmitting a rescue request to the command center and entering a call queuing waiting state if the rescue response information of other vehicles is not received. The invention also discloses an automatic vehicle call-for-help system for realizing the method. Automatic contact and mutual rescue between vehicles, contact between the vehicle and the service center and the rescue are combined, so that the rescue time of a vehicle accident is greatly shortened.

The invention discloses a vehicle-mounted accident informing system, which comprises mobile intelligent electronic equipment and vehicle-mounted accident monitoring equipment arranged on a car, wherein the vehicle-mounted accident monitoring equipment comprises a vibration sensor, an infrared sensor, an inclination sensor, a processing module, a Bluetooth module and a GPS (Global Positioning System) module; the mobile intelligent electronic equipment comprises a processing unit, a Bluetooth unit and a remote wireless communication unit. When signals of the three sensors are greater than a preset threshold value, a phone call is made or a short massage is sent to a preset phone number through the system so as to inform the occurrence and place of an accident. By adopting the system, relevant departments or relatives and friends can be informed of the place of the accident in time, so that the death rate and disability rate in car accidents are lowered to the maximum extent, and the timelines of rescue is ensured. The invention further relates to a car accident informing method.

The invention provides a minimum risk control strategy for an automatic driving vehicle, which considers that a vehicle take-over evaluation model and a vehicle parking evaluation model are established under the condition that the vehicle is separated from an automatic driving mode, and the minimum risk control strategy for the automatic driving vehicle is established in the vehicle take-over evaluation model/the vehicle parking evaluation model. A feasible vehicle takeover mode/vehicle parking mode is used as evaluation content, evaluation indexes are set according to the evaluation content, evaluation factors are set according to the evaluation indexes, risk level judgment standards are made for the evaluation factors and the evaluation indexes, and the evaluation indexes are comprehensively evaluated by combining actual risk levels of the evaluation factors. And finally, a vehicle takeover mode/vehicle parking mode is decided according to a comprehensive evaluation result of the evaluation indexes, so that safe parking of the automatic driving vehicle is realized, and the risk of vehicle accidents is reduced to the greatest extent.
