Method and apparatus for vehicle extrication, electronic device and storage medium

An apparatus for vehicle extrication, applied to a four-motor drive system, wherein the four-motor drive system comprises a front motor assembly, a rear motor assembly, and an air suspension;

• the air suspension comprises an air spring provided corresponding to each wheel;
• wherein the apparatus comprises a processor, and a memory communicatively connected to the processor, the memory is stored with a computer-executable instruction, and the processor executes the computer-executable instruction stored in the memory to:
• receive an extrication mode activation signal, and switch a vehicle driving mode from a normal mode to an extrication mode;
• acquire, in the extrication mode, an alternating drive frequency of the front motor assembly and the rear motor assembly;
• acquire a current pressure value of each air spring collected by the air suspension;
• calculate and obtain, based on the pressure value of each air spring, a current natural frequency of the air suspension;
• calculate and obtain a drive power corresponding to the front motor assembly and a drive power corresponding to the rear motor assembly based on the pressure value of each air spring;
• control the air suspension to vibrate up and down according to the current natural frequency of the air suspension;
• and
• based on the alternating drive frequency, alternately drive the front motor assembly and the rear motor assembly according to respective drive powers corresponding to the front motor assembly and the rear motor assembly, until an extrication mode exit signal is received, exit the extrication mode and switch to the normal mode.

A non-transitory computer-readable storage medium, wherein the computer-readable storage medium is stored with a computer-executable instruction, and the computer-executable instruction, when executed by a processor, is configured to:

• receive an extrication mode activation signal, and switch a vehicle driving mode from a normal mode to an extrication mode;
• acquire, in the extrication mode, an alternating drive frequency of the front motor assembly and the rear motor assembly;
• acquire a current pressure value of each air spring collected by the air suspension;
• calculate and obtain a current natural frequency of the air suspension based on the pressure value of each air spring;
• calculate and obtain, based on the pressure value of each air spring, a drive power corresponding to the front motor assembly and a drive power corresponding to the rear motor assembly;
• and
• control the air suspension to vibrate up and down according to the current natural frequency of the air suspension;
• and alternately drive, based on the alternating drive frequency, the front motor assembly and the rear motor assembly according to respective drive powers corresponding to the front motor assembly and the rear motor assembly, until an extrication mode exit signal is received, exit the extrication mode and switch to the normal mode.
