What does the car center console refer to?

Car center console is the place where comfort and entertainment devices such as car air conditioning and audio are controlled. The car center console includes a central control door lock system, allowing the driver to control the opening and closing of all car doors and the window lifting system. The car center console also includes a central control panel with various vehicle controllers such as the audio control panel. The central control door lock system mainly has three functions: central control, speed control, and individual control. The driver can control all door locks, and when the driving speed reaches a certain level, the doors automatically lock. For other doors, there are independent switches, allowing each door to be controlled individually. The principle of the central lock: The wireless remote control function of the central lock: refers to the ability to open and lock doors remotely without inserting the key into the lock hole. Its biggest advantage is that, regardless of day or night, there is no need to locate the lock hole, and unlocking (opening) and locking (locking) can be done conveniently from a distance. Basic principle of remote control: A weak radio wave is emitted from the owner's side, received by the car antenna, and the signal code is identified by the electronic control unit (ECU). Then, the actuator (motor or electromagnetic coil) of the system performs the action of opening or closing the lock. This system mainly consists of two parts: the transmitter and the receiver. Transmitter: Composed of a transmission switch, transmission antenna (keypad), integrated circuit, etc. The keypad is integrated with the signal transmission circuit. From the identification code storage circuit to the FSK modulation circuit, the use of a single-chip integrated circuit makes it compact, with a button-type lithium battery installed on the opposite side of the circuit. The transmission frequency is selected according to the radio wave regulations of the country of use, generally using 27, 40, or 62 MHz frequency bands. Each press of the transmission switch sends a signal once. Receiver: The transmitter sends the identification code using FM modulation, which is received by the car's FM antenna and enters the FM high-frequency amplification processor of the receiver ECU via a distributor for demodulation. The demodulated identification code is compared with the preset one; if it is correct, the control circuit is activated, and the actuator operates. The door lock remote control system usually consists of one portable transmitter and one in-car receiver. The identifiable signal sent by the transmitter is received and decoded by the receiver, which then drives the door lock to open or lock. Its main function is to facilitate the driver in locking or unlocking the doors.
