[0002] Modern car users have increasingly higher requirements for intelligence, and the layout of dashboard interiors is becoming more and more concise. However, traditional cockpit systems have low levels of intelligence and humanization, and are not easy to operate, which brings troubles to users.

[0003] For example, the Chinese patent document with publication number CN205836765U discloses a car anti-theft and anti-collision door lock remote control system including a vibration sensor, an inverter, a single-chip microcomputer, a control circuit, a power module, a voice module, an anti-theft key switch, a wireless communication module, a remote control, an alarm module and a key input. The output end of the power module is connected to the power interface of the single-chip microcomputer; the single-chip microcomputer is connected to the input end of the wireless communication module; the wireless communication module is connected to the remote control; the output end of the key input is connected to the input end of the remote control; the output end of the remote control is connected to the input end of the alarm module; the above patent disclosure technology has the following problems: in the process of remote control of the vehicle door lock, the basic logic it implements is only a simple opening and closing of the door lock, and it cannot realize intelligent door locks and interactive linkage effects by recognizing various actions through sensors. The existing technology is not easy to solve such problems. Therefore, there is an urgent need for an intelligent cockpit control system to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent cockpit control system, which aims to provide a control system that can intelligently control the vehicle's on and off and parking.

[0005] To achieve the above objectives, the present invention provides an intelligent cockpit control system for commercial vehicles, including: an intelligent cockpit controller, a remote control key, a display screen, a door lock, an audio and visual alarm device, an indoor camera, an air pressure sensor, an air pump, an electronic parking unit, an air conditioner, an indoor temperature sensor, an intelligent power distribution system, and a vehicle CAN network.

[0006] Furthermore, the input end of the intelligent cockpit controller is respectively connected to the display screen, the indoor camera, the door lock, the sound and light alarm device, the air pressure sensor, and the air pump;

[0007] The display screen is the interface between the intelligent cockpit controller and the driver; the intelligent cockpit controller collects cockpit information through the indoor camera;

[0008] The remote control key is connected to the Bluetooth module of the smart cockpit controller;

[0009] Furthermore, the input end of the air conditioning controller is connected to an indoor temperature sensor;

[0010] The intelligent cockpit controller, electronic parking unit, air conditioner, and intelligent power distribution are connected to the vehicle CAN network as a CAN node;

[0011] Furthermore, after the intelligent cockpit controller detects that the driver unlocks the vehicle using the remote control key outside the vehicle, it wakes up the network through the vehicle's CAN network and sends a low-voltage power-on command. After receiving the command, the intelligent power distribution controls the low-voltage power-on of the entire vehicle.

[0012] Furthermore, after the camera detects that someone is sitting in the cab, the intelligent cockpit controller wakes up the network through the vehicle's CAN network and sends a high-voltage power-on command. After receiving the command, the intelligent power distribution controls the high-voltage power-on of the entire vehicle.

[0013] Furthermore, after the vehicle is powered on, if it is detected that the driver has locked the door using the remote key outside the vehicle, and the camera detects that there is no one in the cab, the intelligent cockpit controller sends a power-off command through the vehicle CAN network, and the door locks are locked;

[0014] Furthermore, after the vehicle is powered on, if it is detected that the driver has locked the door with the remote key outside the vehicle, but the camera detects that there is someone in the cab, the intelligent cockpit controller sends a prohibition power-off command through the vehicle CAN network, unlocks the door locks, and drives the sound and light alarm device to alarm;

[0015] Furthermore, after the vehicle is powered on at low voltage, the camera detects that there is someone in the cab, parking is valid, and the air-conditioning system is off, the smart cockpit controller starts the first timer for T1 time, and the smart cockpit controller sends the air-conditioning to start external circulation command through the vehicle CAN network, and the air-conditioning system starts the external circulation to keep the air in the cabin fresh; further, after the air-conditioning system is turned on, the smart cockpit controller starts the second timer for T2 time to keep the air in the cabin fresh, and the smart cockpit controller sends the air-conditioning system to stop command through the vehicle CAN network, and the air-conditioning system is turned off.

[0016] Furthermore, the cooling and heating power of the air conditioner can be actively adjusted according to the ambient temperature of the cab to maintain the comfort of the cab.

[0017] Furthermore, if the air conditioner detects that the indoor ambient temperature is higher than a first threshold, it actively turns on the cooling mode. Furthermore, if the air conditioner detects that the indoor ambient temperature is lower than a second threshold, it actively turns on the heating mode. The driver can set the first and second thresholds through the display screen. If the indoor ambient temperature is lower than the first threshold and higher than the second threshold, the air conditioning system will not be actively turned on.

[0018] Further, after the high-voltage electricity on the whole vehicle, the intelligent cockpit controller detects when the air pressure is low, controls the air pump to work, and prohibits the parking release at the same time, when the air pressure reaches the upper limit, stops working, and allows the parking release at the same time;

[0019] Further, the electronic parking unit receives vehicle speed information and throttle pedal opening degree information through the whole vehicle CAN network, when the vehicle speed is equal to 0 and the throttle pedal opening degree is equal to 0, the electronic parking unit pulls up the hand brake; when the throttle pedal opening degree is greater than 0 and is a valid value, the electronic parking unit releases the hand brake;

[0020] Further, when the indoor camera monitors that the main driver seat is empty, the electronic parking unit is prohibited from responding to the parking release instruction;

[0021] Further, the cockpit system controller display screen integrates virtual keys such as power switch and parking switch, cancels the corresponding physical keys, and users can control the vehicle power mode and parking mode through the virtual keys;

[0022] The beneficial effects of the present application are:

[0023] 1. The linkage of the whole vehicle power subsystem, air conditioning subsystem and door lock subsystem makes the cockpit more intelligent.

[0024] 2. The automatic control of parking is realized, the car is prevented from slipping due to forgetting to pull the hand brake, the introduction of the camera monitoring avoids the misoperation of children, and the human-machine experience is safer.

[0025] 3. Through the functions of active power supply, active parking, active air conditioning and active unlocking, the intelligent control of the cockpit is realized, the physical power switch and the physical parking switch are reduced, the instrument table is more simple, and the comfort of the cab is improved.

DETAILED DESCRIPTION

[0031] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are intended to illustrate and explain the present application, and are not intended to limit the present application.

[0032] Reference Figure 1 , a structure diagram of an intelligent cabin control system is shown;

[0033] As Figure 1 shown, in the embodiment, the intelligent cabin control system comprises an intelligent cabin controller 101, a remote key 102, a display screen 103, an indoor camera 104, a door lock 105, an air pressure sensor 106, an air pump 107, a sound and light alarm device 108, a Bluetooth module 109, a whole vehicle CAN network 110, an air conditioning system 111, an electronic parking unit 112, intelligent power distribution 113, and an indoor temperature sensor 114.

[0034] Further, the input end of the intelligent cabin controller 101 is connected with the display screen 103, the indoor camera 104, the door lock 105, the air pressure sensor 106, the air pump 107, and the sound and light alarm device 108, respectively;

[0035] The display screen 103 is an interface for human-computer interaction between the intelligent cabin controller 101 and the driver.

[0036] The intelligent cabin controller 101 collects the cab information through the indoor camera 104;

[0037] The remote key 102 is connected with the Bluetooth module 109 of the intelligent cabin controller 101;

[0038] Further, the input end of the air conditioning system 111 is connected with the indoor temperature sensor 114 for detecting the ambient temperature in the cab;

[0039] The intelligent cabin controller 101, the air conditioning system 111, the electronic parking unit 112, and the intelligent power distribution 113 are connected as a CAN node to the whole vehicle CAN network 110;

[0040] As Figure 2 shown, a power subsystem control logic of an intelligent cabin control system,

[0041] Furthermore, in step S1, the smart cockpit controller 101 detects that the driver unlocks the vehicle through the remote control key 102 outside the vehicle, wakes up the network through the vehicle CAN network 110, and sends a low-voltage power-on instruction. After receiving the instruction, the smart power distribution 113 controls the low-voltage power-on of the vehicle.

[0042] Furthermore, in step S2, after the camera 104 detects that someone is sitting in the cab, the intelligent cockpit controller 101 sends a high-voltage power-on instruction through the vehicle CAN network 110, and the intelligent power distribution 113 controls the high-voltage power-on of the vehicle after receiving the instruction.

[0043] Furthermore, in step S3, after the vehicle is powered on (including low voltage or high voltage), it is detected that the driver has locked the door by using the remote control key 102 outside the vehicle, and the camera 104 detects that there is no one in the cab, the smart cockpit controller 101 sends a power-off command through the vehicle CAN network 110, and the door lock 105 is locked;

[0044] Furthermore, in step S4, after the vehicle is powered on, if it is detected that the driver has locked the door using the remote control key 102 outside the vehicle, but the camera 104 detects that there is someone in the cab, the smart cockpit controller 101 sends a prohibit power-off command through the vehicle CAN network 110, the door lock 105 is unlocked, and the sound and light alarm device 108 is driven to alarm;

[0045] like Figure 3 As shown, the air conditioning subsystem control logic of an intelligent cockpit control system is

[0046] Further, in step S11, after the vehicle is powered on at low voltage, the camera 104 detects that there is someone in the cab, parking is valid, and the air-conditioning system 111 is turned off. The smart cockpit controller 101 starts the first timer, which lasts for T1 time. The smart cockpit controller 101 sends an air-conditioning start external circulation instruction through the vehicle CAN network. The air-conditioning system 111 turns on the external circulation to keep the air in the cabin fresh; further, the smart cockpit controller 101 starts the second timer, which lasts for T2 time. To keep the air in the cabin fresh, the smart cockpit controller 101 sends an air-conditioning system shutdown instruction through the vehicle CAN network, and the air-conditioning system 111 is turned off.

[0047] Furthermore, in step S12, after the high voltage is turned on to the vehicle, the cooling and heating modes of the air-conditioning system 111 can be actively adjusted according to the ambient temperature of the cab to maintain the comfort of the cab.

[0048] Further, in step S13, after the high voltage is applied to the whole vehicle, if the air conditioning system 111 detects that the indoor environment temperature is higher than a first threshold value, the refrigeration mode is actively started. Further, if the air conditioning system detects that the indoor environment temperature is lower than a second threshold value, the heating mode is actively started. The first threshold value and the second threshold value can be set by the driver through the display screen 103. If the indoor environment temperature is lower than the first threshold value and higher than the second threshold value, the air conditioning system does not actively start.

[0049] As shown in FIG. 1, Figure 4 a parking subsystem control logic of an intelligent cockpit control system,

[0050] Further, in step S21, after the high voltage is applied to the whole vehicle, the intelligent cockpit controller 101 collects the working air pressure information of the brake circuit through the air pressure sensor 106. When the air pressure is lower than a lower threshold value, the air pump 107 is controlled to work, and at the same time, the instruction of prohibiting releasing the hand brake is sent to the electronic parking unit 112 through the vehicle CAN network 110. When the air pressure reaches an upper threshold value, the air pump 107 is controlled to stop working, and at the same time, the instruction of allowing releasing the hand brake is sent to the electronic parking unit 112 through the vehicle CAN network 110.

[0051] Further, in step S22, the electronic parking unit 112 accepts the vehicle speed information and the accelerator pedal opening degree information through the vehicle CAN network 110. When the vehicle speed is equal to 0 and the accelerator pedal opening degree is equal to 0, the electronic parking unit 112 pulls up the hand brake. When the accelerator pedal opening degree is greater than 0 and is a valid value, the electronic parking unit 112 releases the hand brake.

[0052] Further, in step S23, the display screen 103 of the intelligent cockpit controller 101 integrates virtual keys such as the power switch and the parking switch, and cancels the corresponding physical keys. The user can control the power mode and the parking mode of the whole vehicle through the virtual keys. When the indoor camera 104 monitors that the main driver seat is unoccupied, the electronic parking unit 112 is prohibited from responding to the parking release instruction. After the indoor camera 104 fails, the parking can be controlled through the virtual key of the parking switch on the display screen 103.

[0053] In addition, it should be noted that various specific technical features described in the above embodiments can be combined in any appropriate way without contradiction. In order to avoid unnecessary repetition, various possible combinations are not described again by the present application.

[0054] In addition, various different embodiments of the present application can be combined in any appropriate way, as long as they do not contradict the idea of the present application, and they should also be considered as disclosed by the present application.
