[0025] As shown in Figure 3 The second embodiment of the present application provides an automobile intelligent vehicle door projection pedal opening control method based on the prior art, and the method comprises: Step S10, in response to receiving the driver Bluetooth key signal, a first control instruction is generated, and the first control instruction is used to control the light sensing module 502 to perform projection lighting instruction and identify the driver pedal action model; In step S10, the vehicle-mounted Bluetooth module periodically transmits a Bluetooth signal in response to receiving the driver Bluetooth key signal, and the BLE module in the Bluetooth key receives the signal. When the driver carries the Bluetooth key close to the vehicle, the Bluetooth key will respond to the Bluetooth signal transmitted by the vehicle. The Bluetooth key and the vehicle need to be paired at the first use, and a unique pairing code will be generated during the pairing process and stored in the vehicle and the key. After receiving the response signal of the Bluetooth key, the vehicle identifies the Bluetooth key through the unique pairing code in the signal and verifies the legality of the Bluetooth key using an encryption algorithm. The vehicle estimates the distance between the key and the car by detecting the strength of the Bluetooth signal. Through multiple measurements and algorithm optimization, it is determined whether the key is within the effective range. Only when the key is within the effective range, the vehicle will allow subsequent projection, unlocking, starting and other operations.

[0026] The vehicle-mounted Bluetooth module periodically transmits a Bluetooth signal, and the Bluetooth key carried by the driver automatically responds after receiving the signal. Based on the unique pairing code stored during the initial pairing, the vehicle verifies the legality of the Bluetooth key through an encryption algorithm to prevent illegal devices from triggering.

[0027] The vehicle estimates the distance between the key and the vehicle by detecting the strength of the Bluetooth signal, and confirms that the key is within the preset effective range through multiple measurements and algorithm optimization to avoid false triggering. After verification, the controller 501 generates a first control instruction to synchronously trigger two tasks of the light sensing module 502: providing a signal basis for the subsequent start of the projection lamp module 40 and entering a real-time monitoring state of the light sensing module 502.

[0028] In step S20, the light intensity parameters of the vehicle surroundings are received, the projection pattern illumination parameters of the projection lamp are adjusted, and the projection instruction is executed. In step S20, the light sensing module 502 receives the illumination parameters of the vehicle surroundings in real time and transmits the data to the controller 501. The controller 501 automatically calculates and adjusts the illumination parameters of the projection lamp module 40 according to the illumination parameters: increases the projection brightness in strong light environment to avoid the pattern being submerged; reduces the brightness in weak light environment to prevent glare and save energy. After the adjustment is completed, the projection lamp module 40 projects the preset pattern through the lens module 20 to provide visual guidance for the driver.

[0029] In step S30, a second control instruction is generated for sending an opening door instruction to the intelligent vehicle door opening controller and a projection flashing prompt instruction. In step S30, the light sensing module 502 cooperates with the millimeter wave radar embedded in the controller 501 to collect the distance, radial velocity and angle of the target foot, accurately capture the motion trajectory; the controller compares the real-time data with the preset foot pedal motion model, confirms the effective motion, and generates a foot pedal success signal. The controller 501 generates a second control instruction based on the foot pedal success signal, including two sub-instructions: sending a door opening instruction to the intelligent vehicle door opening controller; sending a projection flickering prompt instruction to the projection lamp module 40, feeding back that the action has been recognized, and the door will be opened soon.

[0030] In step S40, the intelligent vehicle door opening execution controller receives the door opening signal, and the intelligent vehicle door opening mechanism executes the door opening instruction. The dirt detection module 502 detects that the cleanliness is abnormal, sends a glass automatic cleaning or heating deicing instruction to the vehicle door opening controller, and sends it to the cleaning nozzle module 30.

[0031] In step S40, after the intelligent vehicle door opening controller receives the door opening signal, the door opening mechanism is driven to execute the opening action, and the door unlocking and opening are completed. If the dirt detection module 502 detects that the surface cleanliness of the lens module 20 is abnormal, it immediately sends a signal to the controller 501; the controller 501 triggers a linkage instruction: controls the cleaning nozzle module 30 to spray water to clean the lens; if ice is detected, the nozzle heating module 40 is started to heat and deice at the same time, to ensure that the projection and motion recognition function are not hindered.

[0032] The third embodiment of the present application provides a vehicle on the basis of the prior art, which comprises an automobile intelligent vehicle door projection foot pedal opening control system.

[0033] With the vehicle of the embodiment, the vehicle is equipped with the above-mentioned intelligent vehicle door projection pedal opening control system, and has the following advantages: the controller housing 10 provides an integrated installation basis for the lens module 20, the projection lamp module 40, the PCB component 50, etc. through the assembly space surrounded by the front housing 101, the heat sink 103 and the rear housing 102, ensuring compact layout and stable connection; the PCB board body 504 in the PCB component 50 is provided with the controller 501 and the light sensing module 502 on both sides, which can accurately collect target parameters and improve the pedal action recognition accuracy in cooperation with the millimeter wave radar embedded in the controller 501; the light sensing module 502 can also feedback the environmental illumination in real time, and the controller 501 can adjust the brightness of the projection lamp module 40 to adapt to different environments; at the same time, the cooperation of the cleaning nozzle module 30, the dirt detection module 502 and the nozzle heating module 40 can effectively remove the dirt and frost on the surface of the lens module 20, reduce the influence of external factors on the projection clarity and the action recognition stability, and improve the intelligence, convenience and all-scene reliability of the vehicle door opening.
