Description

[0001] manual Technical Field

[0002] This invention relates to the fields of vehicle intelligent control and vehicle body domain controller timing linkage technology, specifically to a vehicle multi-scenario timing linkage control system. Background Technology

[0003] As the level of intelligence in automobiles continues to improve, vehicles are generally equipped with various in-vehicle functional modules such as keyless entry, welcome lights, seat adjustment, air conditioning presets, fragrance release, and driving ambient lighting.

[0004] Currently, most functions in existing models are independently developed and controlled in a decentralized manner, lacking a unified master control scheduling and timing coordination logic between modules; the triggering logic is simplistic, relying solely on simple distance sensing, failing to distinguish between pedestrian passing and user directional approach to the vehicle, easily leading to invalid false triggers; simultaneously, ambient lighting during driving only supports fixed mode switching, unable to establish a quantitative mapping relationship with vehicle operating condition signals such as throttle opening, braking, and steering, resulting in poor adaptability; furthermore, personalized cockpit configurations for different users are mostly stored locally on a standalone basis, unable to achieve cloud-based cross-vehicle synchronous access, resulting in insufficient ease of use. Summary of the Invention

[0005] 1. Purpose of the invention

[0006] The present invention aims to overcome the shortcomings of existing technologies such as decentralized and independent control of vehicle functions, asynchronous timing of multi-device linkage, easy misjudgment of sensor triggering, lack of quantitative matching between driving light effects and operating conditions, and inability to synchronize user configurations across vehicles, and provides a vehicle multi-scenario timing linkage control system.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A vehicle-mounted multi-scenario time-series linkage control system includes a vehicle perception module, an vehicle-mounted execution module, and a main control processing unit;

[0010] The vehicle perception module includes an identity recognition submodule, a distance sensing submodule, a seating detection submodule, and a vehicle operating condition acquisition submodule.

[0011] The main control processing unit is communicatively connected to the vehicle perception module and the vehicle execution module, respectively.

[0012] The main control processing unit is configured to execute the following control logic:

[0013] When the distance sensing submodule detects a legitimate user approaching the vehicle from a distance, and the identity recognition submodule verifies the identity, the first linkage control sequence is triggered, driving the vehicle execution module to perform the welcoming combination action.

[0014] When the seating detection submodule detects that the user has finished taking a seat, it triggers the second linkage control sequence, driving the vehicle execution module to perform the cabin privacy adaptation combination action;

[0015] When the vehicle condition acquisition submodule acquires driving condition signals, it dynamically matches the light rhythm output strategy according to the condition parameters.

[0016] When the distance sensing submodule detects that a legitimate user has moved away from the vehicle to a preset distance threshold, it triggers the third linkage control sequence, driving the on-board execution module to perform the vehicle departure closing and locking combination action.

[0017] Furthermore, the system is configured with user approach discrimination logic: based on the rate of change of the distance sensing signal intensity, it distinguishes between passing vehicles and vehicles heading in a specific direction, and only triggers the welcoming sequence when it is determined to be heading in a specific direction, thus avoiding invalid and false triggering.

[0018] Furthermore, it supports multi-user identity storage and cloud synchronization, with different identity accounts associated with independent preset parameters for lighting, seats, air conditioning, and fragrance. Once the identity is recognized, the corresponding personalized configuration is automatically invoked.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the present invention has the following technical advantages:

[0021] First, by adopting multi-sensor signal fusion and unified timing scheduling of the main control, the limitations of independent control of each functional module in the traditional system are broken, and the orderly and coordinated start-up and shutdown of multiple devices and the synchronization of action timing are achieved.

[0022] Second, a distance signal strength change rate discrimination mechanism is introduced to accurately distinguish between pedestrians passing by and users approaching, greatly reducing the probability of false system triggering;

[0023] Third, by collecting driving condition parameters through the vehicle's CAN bus, a quantitative mapping relationship is established between the condition values ​​and the light-emitting speed, brightness, and mode of the ring light, so as to achieve dynamic adaptive lighting effect output.

[0024] Fourth, a multi-user parameter cloud storage and synchronization architecture is built to support cross-vehicle access to personalized cockpit configurations from different accounts, thereby improving intelligent adaptation capabilities.

[0025] Fifth, the overall architecture is based on existing vehicle sensors and execution hardware, without the need for additional dedicated hardware, and is compatible with the existing vehicle electrical architecture, making it easy to mass-produce and implement. Detailed Implementation

[0026] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The present invention relates to a vehicle-mounted multi-scenario time-series linkage control system, which consists of a vehicle perception module, a vehicle-mounted execution module, and a main control processing unit.

[0028] The vehicle perception module includes an identity recognition submodule, a distance sensing submodule, a seating detection submodule, and a vehicle condition acquisition submodule. Identity recognition can use any one or more combinations of Bluetooth keys, NFC, and facial biometrics. Distance sensing uses millimeter-wave radar or an ultra-wideband sensing module. Seating detection uses a seat pressure sensor. The vehicle condition acquisition submodule exchanges data in real time through the vehicle's CAN bus.

[0029] The main control processing unit adopts a vehicle domain controller or an on-board central computing unit to receive signals from various sensing sub-modules in a coordinated manner, and has built-in timing scheduling logic, proximity discrimination algorithm, and working condition lighting effect mapping algorithm.

[0030] The first linkage control sequence includes at least two of the following: door pre-unlocking, exterior lights gradually illuminating, cabin lights gradually turning on, air conditioning pre-adjusting to a preset temperature, and fragrance module releasing at a low level.

[0031] The second linkage control sequence includes at least two of the following: the non-passenger area lighting is turned off in stages, the seat posture is adjusted adaptively, the windows and sunshades are closed, and the in-vehicle audio is switched to silent mode.

[0032] The vehicle operating condition acquisition submodule acquires throttle opening, braking pressure, steering angle, and vehicle speed signals through the vehicle's CAN bus; the main control processing unit linearly maps the 0–100% throttle opening parameters to a circular light strip with a light flow speed of 0.2–2 m / s.

[0033] The mathematical relationship of linear mapping is defined as follows:

[0034] V = 0.018 × A + 0.2

[0035] In the formula: A is the throttle opening percentage, 0≤A≤100, in units of %; V is the light strip trailing speed, in units of m / s.

[0036] When the throttle opening A=0%, the light stream speed is guaranteed to be at least 0.2m / s; when the throttle opening A=100%, the light stream speed reaches its maximum value of 2.0m / s, increasing linearly and uniformly throughout the entire process without jumps or breaks, achieving a smooth dynamic light effect that matches the acceleration depth.

[0037] When the brake master cylinder pressure exceeds the preset threshold, the ring light strip is controlled to flash bright red light for 0.5 seconds to achieve quantitative linkage output between driving conditions and lighting effects.

[0038] User approach detection logic: Continuously collect multiple frames of distance sensing signals, calculate the rate of change of signal strength. If the strength increases steadily, it is determined that the user is directionally approaching the vehicle, triggering the welcoming sequence; if the signal is fluctuating and does not have a stable increasing trend, it is determined that a passerby is passing by, and no linkage action is triggered.

[0039] Multi-user configuration cloud synchronization: Establish multi-user identity profiles, with each identity independently bound to parameters such as headlight brightness, headlight gradient duration, air conditioning preset temperature, seat fore-aft and backrest angles, and fragrance level; after identity recognition is successful, the main control unit automatically retrieves the corresponding personalized parameters and completes the adaptation adjustment; all configuration parameters are synchronously stored in the cloud, supporting cross-vehicle synchronous access for the same user account across adapted models.

[0040] The third linkage control sequence includes: cabin lights gradually turning off from near to far, fragrance and air conditioning turning off in sequence, automatic locking of all doors, and automatic activation of the vehicle anti-theft arming mode.

[0041] In this invention, the light-off logic of the second linkage control sequence and the third linkage control sequence are independent of each other, have different scenarios, and do not conflict:

[0042] The tiered lighting shutdown during the seating phase is an adaptation logic for seating, which only turns off the lights in non-driver and passenger areas such as the front passenger seat and rear seats, while retaining basic lighting in the driver's seat; the step-by-step lighting shutdown during the exit phase is a reverse-chronological reset process of the welcome light sequence, which gradually turns off all cabin lights from the driver's seat outwards towards the door; the two actions have completely different triggering scenarios, triggering times, and controlled objects, and do not interfere with each other. Attached Figure Description

[0043] Figure 1 This is a block diagram of the overall system architecture of the present invention;

[0044] This invention demonstrates the overall structure of the vehicle-mounted multi-scenario timing linkage control system, clearly dividing it into three major layers: the perception layer, the core control layer, and the execution layer. The perception layer includes an identity recognition submodule, a distance sensing submodule, a seat detection submodule, and a vehicle operating condition acquisition submodule. The core layer is the main control processing unit, responsible for signal processing, logic discrimination, and timing scheduling. The execution layer integrates the door control unit, seat adjustment unit, multi-level lighting unit, window sunshade unit, steering wheel ring light strip unit, air conditioning unit, fragrance unit, and anti-theft locking unit. All modules are uniformly scheduled by the main control processing unit to achieve coordinated control of all vehicle equipment.

[0045] Figure 2This is a flowchart of the multi-sensor sensing signal fusion and discrimination logic of the present invention;

[0046] The system demonstrates the user approach detection process to prevent false triggering. It simultaneously collects multiple distance sensor signals and performs filtering preprocessing, continuously calculating the signal strength change rate. If the signal strength shows no stable increasing trend, it is determined to be a pedestrian passing by, and no action is triggered. If the signal strength continues to increase steadily, it is determined to be a legitimate user heading towards the vehicle, and the welcoming sequence preparation work is initiated, logically avoiding invalid false triggering issues.

[0047] Figure 3 This is a schematic diagram of the three-stage timing linkage control process of the present invention;

[0048] This invention presents the core of its irreversible serial main timing sequence and parallel background operation branches. The main timing sequence is divided into three stages: The first stage is the user approach welcoming stage, after completing identity verification and distance determination, simultaneously executing linked actions such as unlocking, lighting, air conditioning pre-adjustment, and fragrance release; The second stage is the seating privacy adaptation stage, after detecting that the user has sat down, turning off the non-driver area lighting, adjusting the seat, closing the windows, and switching the audio to silent mode, while the background continuously collects vehicle operating condition signals through the CAN bus; The third stage is the departure final locking stage, after detecting that the user has moved away to a preset distance threshold, sequentially completing actions such as gradually turning off the lights, shutting down the vehicle's electrical appliances, automatically locking all doors, and activating the vehicle's anti-theft arming; Vehicle operating condition collection and dynamic lighting effect adjustment are parallel branches, running in a loop in the background throughout the entire process.

[0049] Figure 4 This is a schematic diagram illustrating the quantitative mapping relationship between driving conditions and ring-shaped lighting effects according to the present invention.

[0050] This demonstrates the logic behind the correspondence between vehicle driving parameters and the steering wheel ring light strip effect. The system collects four types of operating condition data in real time via the CAN bus: throttle opening, vehicle speed, braking pressure, and steering angle. The main control unit uses a built-in linear mapping algorithm to calculate: based on the formula {V=0.018 × A + 0.2}, the throttle opening A (0~100%) is linearly converted into a light strip beam speed of 0.2~2.0 m / s. When excessive braking pressure is detected, the light strip is controlled to flash brightly for 0.5 seconds. When steering actions are recognized, the light strip is driven to create a single-sided flowing indicator effect, achieving dynamic linkage between driving status and lighting effects.

[0051] Figure 5 This is a diagram illustrating the multi-user identity recognition and cloud parameter synchronization architecture of the present invention.

[0052] This describes the storage, retrieval, and cross-device synchronization mechanism for multi-user personalized configurations. The system can create multiple independent user identity profiles, each bound to exclusive cabin parameters such as lighting, air conditioning, seats, and fragrance. After identity recognition, the system automatically retrieves the corresponding profile parameters and completes cabin adaptation. All personalized configurations are synchronously uploaded to the cloud server, supporting cross-vehicle synchronization and retrieval by the same user account across multiple adapted models, improving ease of use.
