and the main control chip is used for controlling the first motor driver to drive the door lock motor to execute the unlocking action of the vehicle door when receiving the unlocking signal.
It should be noted that, during the whole vehicle feeding, the central controller cannot work, cannot receive the unlocking signal sent by the key, and cannot send an effective unlocking instruction to the vehicle door module, so that the door module normally works in the emergency state of feeding by adding the standby battery and the bluetooth receiving chip in the traditional vehicle door module, and receives and processes the unlocking signal through bluetooth to drive the vehicle door motor to execute vehicle door unlocking, so that emergency unlocking can be realized under the condition that the vehicle door cannot be normally unlocked through a remote control key or a mechanical key under the whole vehicle feeding condition.

Therefore, the situations that the hidden door handle cannot be unfolded and the mechanical key cannot be used can be solved.
In specific implementation, in the automobile door module control system provided by the embodiment of the invention, the capacity range of the backup battery is preferably 1000mAh to 2000 mAh.
In practical application, the working current of the door lock motor can reach 8A when the door lock motor operates, but the operation time is very short, and the unlocking action can be completed within about 150ms, so that clear unlocking sound can be heard; when the door handle motor is unfolded, the working current can reach 5A, and the running time is 4 s. The electric quantity required by each operation process is as follows:
the unit charge quantity required by unlocking the door lock motor is as follows: q1 ═ IT × 4 × 8 ═ 0.15 × 4 × 4.8C;
unit charge amount required for operation of the gate module: q2 ═ IT ═ 0.1 ═ 1 ═ 0.1C;
amount of charge required for the door module to deploy the door handle: q3 ═ IT × 4 ═ 5 × 4 ═ 80C;
the amount of electricity required for the door module to run for 1 minute: q4 ═ Q2 × 60+ Q1+ Q3 ═ 90.8C;
the charge capacity that 2000mAh lithium batteries can provide: q5 ═ IT ═ 2 ═ 3600 ═ 7200C;
even if the electric energy conversion efficiency of the lithium battery is only 50%, namely 3600C charge amount is enough for unlocking the automobile door module for many times.
In a specific implementation, in the control system of the door module of the automobile provided in the embodiment of the present invention, the voltage of the backup battery is 3.7V standard lithium battery, and the full-power voltage is 4.2V (power is 100%) and the feeding voltage is 3.2V (power is less than 20%). Preferably, the model of the standby battery is selected from a 18650 lithium battery, which has a larger mechanical strength and a smaller occupied space (65 mm long and 18mm diameter) compared with a square sheet battery, and can be firmly placed on the PCB by metal fasteners and a dispensing process. On the other hand, 18650 batteries have multiple capacities from 1000mAh to 5000mAh for selection.

Taking fig. 4 as an example, the working voltage of the automobile ECU controller is 9-16V, so that 3.7V lithium battery is needed to boost the voltage to 12V to supply power to the automobile door module; when the voltage of the lithium battery drops below 3.2V, a charging device needs to be activated to charge the lithium battery. In fig. 4, the storage battery provides 9-16V for the door module, the internal voltage management chip TLE9262 outputs 5V voltage to supply power to all IC chips on the door module, and simultaneously provides 5V input voltage for the lithium battery charging chip MPS26029, the MPS26029 outputs 4.2V voltage to charge the lithium battery, and the lithium battery output voltage outputs 12V after passing through the boost chip NCV8871 and is provided for the door module as a working power supply. It should be noted that the chips in fig. 4 are all selected from automobile-level chips (non-consumer-level chips) to meet the electrical performance test requirements of the whole automobile.
