Description

Technical Field

[0001] The present invention relates to the technical field of commercial vehicles, and in particular to a method for controlling a vehicle active safety system in a scenario where a person leaves the vehicle. Background Art

[0002] In recent years, as national regulations on vehicle safety have gradually become stricter, market users' demand for vehicle safety has gradually increased, and the technology of intelligent assisted driving related products has become increasingly mature and the cost has gradually decreased, commercial vehicle products have also begun to be equipped with more safety-related assisted driving functions.

[0003] Vehicle safety is typically categorized as passive and active, based on the timing of protective measures. Passive safety protects vehicle occupants, struck vehicles, and pedestrians after an accident. Active safety, on the other hand, involves a series of auxiliary devices and technologies, automatically intervening to prevent accidents before they occur when the vehicle is on the verge of losing control. Currently, the focus of commercial vehicle development is on active safety technologies, such as ABS (Anti-lock Braking System), ESC (Electronic Stability Control), FCW (Forward Collision Warning), and AEB (Automatic Emergency Braking).

[0004] Current vehicle active safety control systems primarily focus on safety control in scenarios where people are driving or riding, but lack attention to active safety control in scenarios where people are leaving the vehicle. Scenarios where people are leaving the vehicle can be divided into driver leaving and passenger leaving according to the attributes of the people leaving the vehicle; and can be divided into states such as preparing to leave, leaving, and already leaving according to the state of the leaving process. In scenarios where people are leaving the vehicle, there may be safety hazards such as people leaving the vehicle before it has come to a complete stop, the vehicle moving while people are leaving, and the vehicle not being effectively parked after people have left. Although the safety risks in scenarios where people are leaving the vehicle are not as complex and dangerous as those in scenarios where people are driving or riding, the potential for safety hazards cannot be ignored, especially since commercial vehicles are large in size and heavy in weight, and are prone to causing greater collateral damage. To this end, we propose a vehicle active safety system and control method for scenarios where people are leaving the vehicle. Summary of the Invention

[0005] The purpose of the present invention is to provide a vehicle active safety system and control method in a occupant-out-of-vehicle scenario, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The control method includes the following steps:

[0009] S1: The vehicle central controller collects and analyzes human behavior and vehicle status to determine the driver or passenger's status, including whether they are preparing to leave the vehicle, leaving the vehicle, or have left the vehicle.

During the process of the person exiting the vehicle, it has the functions of warning the surrounding environment of the vehicle, locking the parking lock during the person exiting the vehicle, and warning the risk of parking on a slope.

[0013] S5: The judgment of the vehicle leaving status and the event response operation are as follows: the vehicle central controller judges the vehicle leaving status by the person parking and locking the vehicle; after the person has left the vehicle, the vehicle central controller regularly monitors the vehicle surrounding environment through external sensors.

[0014] Preferably, the human behavior sensor is used to sense the in-vehicle behavior of the driver and passengers, and the vehicle state sensor is used to sense the operating state of the vehicle, including the vehicle's own state and the vehicle environment state.

[0015] Preferably, the personnel behavior sensor and vehicle status sensor adopt mechanical-electronic devices and optical-electronic devices, and also share sensors supporting other electronic systems on the vehicle.

[0016] Preferably, the vehicle central controller is used to receive perception data from various personnel behavior sensors and various vehicle status sensors, and send control information to the vehicle braking control execution device according to the active safety system control strategy.

[0017] Preferably, the vehicle central controller also has an I / O interactive interface and bus access to transmit control information with other electronic systems of the vehicle to achieve functional linkage control.

[0018] Preferably, the vehicle brake control execution device is used to execute the control scheme decided by the vehicle central controller. The vehicle brake control execution device is based on the vehicle's existing service brake and parking brake systems, and relies on electrification and electronic control to realize its functions.

[0019] Preferably, the remote communication device is used to transmit safety events generated when people leave the vehicle to the driver and the fleet company's vehicle supervisor, so that the supervisor can grasp and deal with potential safety issues in a timely manner; the vehicle can also receive remote control instructions from the supervisor.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Example 1 reference Figure 1 A vehicle active safety system in a occupant-leaving-vehicle scenario includes a occupant behavior sensor, a vehicle status sensor, a vehicle central controller, a vehicle brake control execution device, and a remote communication device. The vehicle central controller is connected to the occupant behavior sensor, the vehicle status sensor, the vehicle brake control execution device, and the remote communication device. The remote communication device is in a two-way communication connection with the vehicle central controller.

[0033] The occupant behavior sensor detects the driver and passenger's in-vehicle behavior. The vehicle status sensor detects the vehicle's operating status, including its own state and the state of its surroundings. The occupant behavior sensor monitors occupant behavior, such as removing seatbelts, opening doors, and leaving seats. Signal acquisition uses sensors to directly identify occupant behavior: seatbelt removal / insertion detection utilizes a mechanical self-reset switch; door opening / closing detection uses a mechanical travel switch, a sensor shared with the DCM door control system; and seat leaving / entering detection utilizes a built-in pressure switch.

[0034] The personnel behavior sensor and vehicle status sensor use mechanical-electronic devices and optical-electronic devices, and also share sensors of other electronic systems on the vehicle. The vehicle status sensor is used to monitor the vehicle's own status such as motor speed, gear position, speed, brake system pressure, as well as the vehicle's environmental status such as the distance to front and rear obstacles, ground slope, temperature, humidity, etc. Figure 3As shown. These parameters (including but not limited to) serve as input judgment conditions for analysis and calculation by the vehicle's central controller. Sensors can include, but are not limited to, mechanical-electronic devices such as pressure sensors and inclination sensors, optical-electronic devices such as visible light cameras and lidar, and can also share sensors from other vehicle electronic systems, such as speed signals from the motor or engine, and gear signals from the transmission. Motor speed detection uses a common sensor with the motor MCU, with the MCU transmitting data via messages. Transmission gear detection uses a common sensor with the transmission control module (TCM), with the TCM transmitting data via messages. The braking system utilizes a pneumatic fluid transmission system, with a pressure sensor used to detect system pressure. Front and rear obstacle distance detection uses millimeter-wave radar. Ground slope detection uses an inclination sensor. Temperature and humidity use electronic temperature and humidity sensors.

[0035] The vehicle central controller receives sensor data from various human behavior sensors and vehicle status sensors and, based on the active safety system control strategy, transmits control information to the vehicle's brake actuator. The controller also features an I / O interface and bus access to communicate control information with other vehicle electronic systems, enabling interoperable control. The controller utilizes a 32-bit CPU and a 64-point I / O motion controller, along with an embedded real-time control system. The system is stable, reliable, responsive, and highly scalable. The controller receives and processes sensor data from various human behavior sensors and vehicle status sensors, analyzes and determines control strategies for active safety when leaving the vehicle, and transmits control information to the vehicle's brake actuator. Furthermore, the controller is connected to the vehicle's CAN bus, enabling it to communicate control information with other electronic systems, enabling interoperable control.

[0036] The vehicle brake control actuator is used to execute the control scheme determined by the vehicle's central controller. Based on the vehicle's existing service and parking brake systems, the vehicle brake control actuator relies on electrification and electronic control to achieve its functions. It is used to implement braking control schemes for safety risks such as when a person leaves the vehicle before it has come to a complete stop, when the vehicle starts while a person is leaving, or when the vehicle fails to park effectively after a person leaves. The brake control actuator fully integrates the existing mechanical actuators of the service and parking brake systems while also adding an electronic control module. Commercial vehicles commonly use pneumatic brakes, so electronically controlled air valves are added to directly control the supply and exhaust of the brakes.

[0037] The remote communication device is used to transmit safety incidents that occur when people leave the vehicle to the driver and fleet company vehicle supervisors, allowing supervisors to promptly identify and address potential safety issues. The vehicle can also receive remote control commands from supervisors. The remote communication device is used to transmit information such as vehicle rollover risk warnings and rollover alarms even when people are no longer in the vehicle. The vehicle's status can be remotely monitored through internal and external cameras, and control commands can be issued. It uses a GPRS transmission chip and accesses 5G signals, ensuring stable transmission, long distances, and minimal latency.

[0038] Example 2 Figure 2-6 As shown, a control method for a vehicle active safety system in a scene where a person leaves the vehicle is applicable to a vehicle active safety system in a scene where a person leaves the vehicle, comprising the following steps:

[0039] S1: The vehicle central controller collects and analyzes human behavior and vehicle status to determine the driver or passenger's status, including whether they are preparing to leave the vehicle, leaving the vehicle, or have left the vehicle.

[0040] S2: Execute the corresponding control plan according to the real-time status of the vehicle in each subdivision state to avoid the risk of safety accidents;

[0041] S3: Determination of the state of preparing to leave the vehicle and the event response operation are as follows: the vehicle central controller determines the intention of the person to leave the vehicle by detecting the release of the seat belt and the opening of the door, and issues an audible and visual prompt or alarm. Figure 4 As shown, the determination of the ready-to-leave state and event response:

[0042] When the vehicle is moving at a certain speed, ① if the driver's seatbelt is unfastened, the vehicle's central controller (VCC) issues an audible and visual alert via the vehicle's instrument cluster and multimedia system. Simultaneously, if the driver's door is opened, the VCC issues an alert via the VCC and multimedia system, and determines that the driver is preparing to leave the vehicle. At this point, the VCC immediately limits the vehicle's speed, deactivates the accelerator pedal, and simultaneously activates the brakes. The brakes adjust the vehicle's speed to a low speed setting (30 km / h) based on the current vehicle speed and at a preset deceleration rate. The preset deceleration rate at this stage is relatively low to ensure the safety of passengers not wearing seatbelts. ② If the passenger's seatbelt is unfastened and the passenger's door is opened, the VCC issues an alert via the VCC and multimedia system, and determines that the passenger is preparing to leave the vehicle. The VCC immediately limits the vehicle's speed and activates the brakes. The brakes adjust the vehicle's speed to a low speed setting (30 km / h) based on the current vehicle speed and at a preset deceleration rate. The braking process of the vehicle equipped with this solution can use electric motor energy recovery, transmission gear shift (AMT) and other methods to jointly control and reduce vehicle speed;

[0043] S4: The judgment and event response operation of the leaving vehicle state is as follows: the vehicle central controller judges the state of the person leaving the vehicle by detecting the ready-to-leave state mark and the action of leaving the seat, and issues an audible and visual prompt or alarm. At the same time, the vehicle brake control actuator is used to adjust the vehicle speed to stop and park. In S4, during the process of the person leaving the vehicle, it has the functions of vehicle surrounding environment warning, parking lock during the person getting off the vehicle, and slope parking risk warning. Figure 5 As shown, the judgment and event response of the leaving vehicle state:

[0044] When there is vehicle speed, the control system has the following functions:

[0045] ① When the driver's seatbelt is unfastened and the door is opened, and the driver leaves the seat, the vehicle's central controller issues an alarm through the vehicle's instrument cluster and multimedia system, determining that the driver is leaving the vehicle. At this point, the central controller controls the vehicle's speed, disabling the accelerator pedal. Based on the final speed setting for the driver preparing to leave the vehicle, the controller further reduces the vehicle's speed to zero speed using a preset deceleration rate. Simultaneously, the power transmission is cut off and the parking brake is engaged. This solution allows for interlocking braking operations, such as shifting the transmission to neutral (AMT).

[0046] ② When the passenger's seatbelt is unfastened and the door is opened, and the passenger leaves their seat, the vehicle's central controller executes the same control scheme as if the driver were exiting the vehicle. Before the door closes, the parking position is locked to prevent the driver from accidentally starting the vehicle. Once the passenger door is closed, the brakes are released and the vehicle resumes normal driving.

[0047] In the absence of vehicle speed, when the driver or passenger removes their seat belts or opens the door, there will be no sound or light prompts or alarms. At this time, the control system has the following functions:

[0048] ① The vehicle's central controller monitors the vehicle's surroundings through external sensors. If it detects a nearby moving object (≤2m), it will issue a voice prompt to the person getting off the vehicle.

[0049] ② Before passengers get off the vehicle and before closing the doors, the vehicle is locked in parking mode to prevent the vehicle from starting too early and causing the risk of scratching and dragging people.

[0050] ③ When the vehicle senses that it is on a slope, the vehicle's central controller will predict the required hill-holding braking force based on parameters such as vehicle mass and slope, and compare it with the vehicle's theoretical maximum hill-holding braking force. If there is a risk of hill-holding, an early warning will be issued through the vehicle's sound prompt device.

[0051] S5: The judgment and event response operation of the vehicle leaving state is as follows: the vehicle central controller judges the state of the person leaving the vehicle by the person parking and locking the vehicle. In S5, after the person has left the vehicle, the vehicle central controller regularly monitors the vehicle's surrounding environment through external sensors, referring to Figure 6 As shown, the judgment of the vehicle-leaving state and the event response:

[0052] When the driver parks and locks the vehicle, it is determined that the person who entered the vehicle has left the vehicle. The vehicle's central controller then regularly monitors the vehicle's surroundings through external sensors such as multi-directional cameras, millimeter-wave radar, human infrared sensors, humidity and temperature sensors, and rain sensors. The control system then has the following functions:

[0053] ① Obstacle departure warning: The vehicle's central controller can calculate the spatial area required for the vehicle to leave based on the vehicle's parking position and surrounding environment and set it as the recognition zone. When an object (such as a car or motorcycle) stays in this area (staying time > 10 seconds), the vehicle can emit sound and light to remind the object to stay away, so as to ensure the vehicle can leave freely next time;

[0054] ② Slip and slide warning and alarm: The vehicle's central controller can monitor environmental parameters such as humidity, temperature, and rainfall. When a vehicle is parked on a slope and the controller determines that the ground adhesion has decreased, it can issue a slip and slide risk warning to the vehicle supervisor via a remote communication device, allowing supervisors to promptly visit the site and take additional anti-slip measures. At the same time, if the vehicle's transmission system does not rotate and the vehicle's spatial position changes, the control system will determine that it is slipping and slide, and will issue a slip and slide event alarm to the vehicle supervisor so that supervisors can take timely measures to avoid further damage.

[0055] ③ Parking brake failure alarm and emergency anti-slope rolling: The vehicle's central controller can monitor the rotation status of the vehicle's transmission system. When the vehicle is parked on a slope, the controller detects that the transmission system is rotating and determines that the parking brake system has failed and the vehicle is rolling. At this time, the controller will activate the service brake system and use the service brake device for emergency braking to maintain the vehicle's position. It will also send a parking system failure and slope rolling event alarm to the vehicle supervisor. At the same time, the controller can monitor the service brake system pressure. When the pressure is insufficient, it automatically controls the start of the electric air compressor to replenish the brake system pressure.

[0056] ④ Reminder for people staying near the vehicle for a long time: When the vehicle is parked on a slope, the vehicle's central controller can monitor the situation of people around the vehicle. If someone stays near the vehicle for a long time (staying time > 5 minutes), the system will issue a reminder through the voice speaker and external lights to avoid personal injury when the vehicle encounters problems such as sliding down the slope.

[0057] From the above, we can know that:

[0058] The present invention addresses the technical problem: the current active safety control system for vehicles mainly focuses on safety control in scenarios where people are driving or riding, but lacks attention to active safety control of vehicles in scenarios where people are leaving the vehicle. The scenarios where people are leaving the vehicle can be divided into driver leaving the vehicle and passenger leaving the vehicle according to the attributes of the people leaving the vehicle; and can be divided into the states of preparing to leave the vehicle, leaving the vehicle, and having left the vehicle according to the state of the leaving process. In the scenario where people are leaving the vehicle, there may be safety hazards such as people leaving the vehicle before the vehicle has stopped, the vehicle moving while people are leaving the vehicle, and the vehicle not being effectively parked after people have left the vehicle. Although the safety risks in the scenario where people are leaving the vehicle are not as complex and dangerous as those in the scenario where people are driving or riding, the potential safety hazards cannot be ignored, especially since commercial vehicles are large in size and heavy in weight, and are prone to causing greater collateral damage; by adopting the technical solutions of the above-mentioned embodiments and through the above-mentioned settings, this application will certainly be able to solve the above-mentioned technical problems and, at the same time, achieve the following technical effects:

[0060] 2. The present invention focuses on integration with the vehicle's existing electronic and electrical systems.
