Embodiment Construction

[0044] figure 1 is a flow chart of a door lock control method for a vehicle according to an embodiment of the present invention. Such as figure 1 As shown, the door lock control method for a vehicle is used to control the opening of the door lock when the vehicle is submerged, including:

[0045] When the controller receives the water depth signal detected by the water depth sensor, it judges whether the water depth signal exceeds a predetermined value;

[0046] If so, read the signal sent by the pyroelectric sensor, and judge whether the signal sent by the pyroelectric sensor carries a human radiation signal;

[0047] If so, the controller controls the door lock of the vehicle to be opened.

[0048] Here, the predetermined value may be 1.8 meters. Of course, other values ​​can also be used according to the actual situation. If some vehicles are relatively short, the predetermined value is 1.5 meters, and some vehicles are relatively high, then the predetermined value can ...

Abstract

The invention discloses a door lock control method and system for a vehicle and the vehicle, and relates to the technical field of vehicles. The door lock control method for the vehicle is used for controlling a door lock to be unlocked when the vehicle is immersed, and comprises the steps of judging whether or not a water depth signal exceeds a predetermined numerical value when a controller receives water depth signals detected by a water depth sensor; if yes, reading signals emitted by a pyroelectric sensor, and judging whether or not the signals sent by the pyroelectric sensor carry detected human body radiation signals; if yes, utilizing the controller for controlling the door lock of the vehicle to be unlocked. The invention further provides the corresponding door lock control system. Meanwhile, the invention provides the vehicle, and the vehicle adopts the door lock control method for the vehicle for controlling the door lock. By means of the door lock control method and systemfor the vehicle and the vehicle, the door lock of the vehicle can be unlocked when the vehicle is immersed in water, and thus the personal safety of personnel in the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a door lock control method and control system for a vehicle and the vehicle. Background technique [0002] Currently, most vehicles are equipped with airbags, acceleration sensors and airbag controllers. When the vehicle collides, the acceleration sensor detects the acceleration of the vehicle, and the airbag controller judges whether the vehicle collides according to the acceleration signal. If the vehicle collides, the airbag controller sends a collision signal to the body controller. The body controller issues a control command, and the door lock actuator executes the control command to unlock the vehicle door, so that the driver and passengers in the vehicle can safely get out of the collision vehicle. [0003] However, the above-mentioned system is only applicable to the dangerous working condition of the vehicle collision. When the vehicle is in other dangerous working c...
