Detailed Description
In the description of the present application, it is to be noted that, for those skilled in the art, the specific meanings of the above-mentioned terms in the present application can be understood in specific cases. In addition, the technical features mentioned in the different embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.
Some embodiments of the present application provide an automatic unlocking method for a seat belt buckle, which may be applied to a unit or module having a control function in a vehicle, as shown in fig. 1, and the method includes the following steps:
s101: a running speed signal of the vehicle is acquired. The running speed can be obtained according to a vehicle speed sensor arranged on the vehicle, and can also be determined according to functions of a navigation system, a positioning system and the like arranged on the vehicle.
S102: and if the running speed signal indicates that the running speed of the vehicle is zero, acquiring a riding state signal of the passenger. The zero speed situation may include a variety of situations, such as waiting in a queue, or getting off a car at a cut-out.
S103: and if the riding state signal indicates that the rider is in a parking and leaving state, controlling the safety belt lock catch to unlock.
According to the scheme, whether the vehicle is in a parking state is judged through detection of the running speed of the vehicle, whether the passenger is ready to leave the seat to get off is judged through detection of the behavior intention of the passenger, if the passenger is in the parking state, the safety belt lock catch is controlled to be unlocked and opened automatically, manual unlocking of the passenger is avoided, time of the passenger is saved, and convenience is brought to the passenger. The beneficial effect that the scheme of this application compares with current vehicle safety belt unlocking device is that can replace the hand action that triggers safety belt unlocking device to reduce passenger and park operation step and time from the scene under, make the vehicle become more intelligent.
In some embodiments, as shown in fig. 2, the passenger's riding status signal may be obtained by:
s201: and acquiring a gear state signal and an ignition state signal of the automatic transmission type.
S202: if the gear state signal indicates that the current gear is the P gear and the ignition state signal indicates that the vehicle is in a flameout state, step S4 is executed.
S4: and judging that the passenger is in a parking and leaving state.
In the scheme, when the vehicle running speed is zero, a precondition that a scene that a passenger stops and leaves the vehicle is met can be considered. And then, determining the gear by obtaining a signal of a gear sensor of an automatic-gear vehicle type gearbox and the like, and if the gear is identified as a P gear, considering that a further precondition for a scene that a passenger parks and leaves the vehicle is met.
Alternatively, the passenger's riding status signal as shown in fig. 2 may be obtained by:
s301: acquiring a brake state signal and an ignition state signal of a vehicle;
s302: if the brake status signal indicates that the hand brake is in a tensioned state and the ignition status signal indicates that the vehicle is in a flameout state, step S4 is executed.
S4: and judging that the passenger is in a parking and leaving state.
In the scheme, when the vehicle running speed is zero, a precondition that a scene that a passenger stops and leaves the vehicle is met can be considered. And then, the hand brake position is determined by acquiring signals of a hand brake position sensor of a manual gear vehicle type and the like, if the hand brake is identified to be strained, the further precondition for the scene that the passenger parks and leaves the vehicle can be considered to be met, under the condition, when the vehicle is in a flameout state, the third precondition for the scene that the passenger parks and leaves the vehicle can be considered to be met, and the safety belt lock catch is automatically unlocked at the moment.
In the above scheme, the principle of protecting the passenger by the safety belt is to "restrain" the passenger on the seat when a frontal collision occurs, so as to avoid or reduce the collision between the head and the chest and the steering wheel, the instrument panel and the windshield when the passenger continues to move forward under the action of inertia force. It is important whether the vehicle speed is 0. Ensuring that the vehicle speed is already 0 is a precondition for realizing the basic functions of the safety belt and is also a first precondition for unlocking. When the automatic transmission is engaged with the P gear and the manual brake is pulled on the manual transmission, the action can not be cancelled temporarily when the passenger stops or leaves the vehicle. In addition, in the case that the vehicle speed is already 0, it is still necessary to avoid accidents such as serious injury caused by rear-end collision, so that it is required to engage the P gear on the automatic transmission and pull up the hand brake on the manual transmission as a second precondition. The third condition is that the vehicle is turned off by pulling a key or pressing a starting switch, and the action cannot be cancelled temporarily when the passenger stops or leaves the vehicle; moreover, consider operating condition one: in the automatic transmission vehicle, the vehicle speed is already 0 even in a long red light, and the driver may engage in the P range without the intention of parking and leaving the vehicle, so that it is necessary to add the precondition for assisting the determination. Considering a working condition two: even if the vehicle speed is already 0, a driver pulls the hand brake, but the manual gear vehicle still possibly has the problem that the driver accidentally stops the vehicle due to misoperation and does not intend to stop or leave the vehicle, so that the precondition is added for auxiliary judgment. In summary, by judging whether the above 3 conditions are met, the safety belt lock catch can be automatically unlocked and the functional safety can be ensured.
In some embodiments, the step voltage signal is sent to control the opening and closing of a relay in a fuse box of the safety belt lock so as to control whether the safety belt lock is unlocked. In the existing safety belt lock, when an accident occurs, the safety belt lock can be unlocked by controlling the opening and closing of a relay in a fuse box.
In some embodiments of the present application, a storage medium is provided, where program information is stored in the storage medium, and a computer reads the program information and may execute any one of the above methods for automatically unlocking a seatbelt buckle.
Some embodiments of the present application further provide an on-board controller, as shown in fig. 3, including at least one processor 101 and at least one memory 102, where at least one memory 102 stores program information, and after the at least one processor 101 reads the program information, the method for automatically unlocking a seatbelt buckle is performed. The above-mentioned onboard controller may further include: an input device 103 and an output device 104. The processor 101, memory 102, input device 103, and output device 104 may be connected by a bus or other means. The system can execute the method provided by the embodiment of the application, and has the corresponding functional modules and beneficial effects of the execution method.

The vehicle-mounted controller 100 outputs a step voltage signal to control the on/off of a relay in the fuse box, thereby controlling whether a working circuit connected with a vehicle battery is communicated. When the working circuit is communicated, the electromagnet arranged in the lock catch generates suction force to pull the unlocking button, so that the lock tongue of the safety belt is bounced, and the safety belt is unlocked.
The system in the above solution may further include a wheel speed sensor 301, configured to detect a wheel speed and send the wheel speed to the onboard controller 100; the vehicle-mounted controller 100 determines the running speed of the vehicle according to the wheel rotating speed and obtains a running speed signal.
