[0025] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0026] The utility model provides an emergency braking system, which comprises:

[0027] A voice receiving and recognizing unit 1, used for receiving and recognizing voice information;

[0028] The brake drive unit 2 is connected to the brake device 7 of the vehicle and is used to drive the brake device 7 to brake;

[0029] The control unit is connected to the voice receiving and identifying unit 1 and the brake driving unit 2 and is used to control the brake driving unit 2 to start according to the set voice information received and identified by the voice receiving and identifying unit 1.

[0030] Specifically, in order to solve the problem that the existing automobile braking system has high requirements for the driver's concentration, once the driver becomes tired or distracted, other people in the car cannot brake the car; the emergency braking system provided by the utility model has a voice receiving and recognition unit 1, which can receive and recognize voice information, and the control unit can control the brake drive unit 2 to drive the brake unit of the car to brake according to the set voice information received and recognized by the voice receiving and recognition unit 1; that is, when the voice receiving and recognition unit 1 receives and recognizes the set voice information (such as "emergency brake" shouted by the occupants in the car), the control unit can control the brake drive unit 2 to start and perform emergency braking on the car, avoiding dangerous situations caused by the driver's failure to step on the brake pedal in time due to fatigue, distraction, etc.

[0031] Optionally, the control unit includes a normally open switch module 3 and a processing module, and the processing module is used to control the normally open switch module 3 to close according to the set voice information received and recognized by the voice reception and recognition unit 1.

[0032] Specifically, the set voice information can be set as needed, such as: "Hello, brake", "emergency brake", etc. The normally open switch module 3 is in the normally open state, and the power supply of the brake drive unit 2 is disconnected under normal circumstances. When the semantic receiving and recognition unit receives and recognizes that someone in the car has issued a set voice message, the processing module controls the normally open switch module 3 to close and connects the power supply of the brake drive unit 2, so that the brake drive unit 2 can drive the brake device 7 for emergency braking.

[0033] Optionally, a power supply unit 4 is further included, and the power supply unit 4 is electrically connected to the voice receiving and identifying unit 1, the normally open switch module 3 and the brake driving unit 2 to form a closed circuit.

[0034] Specifically, the power supply unit 4 supplies power to the voice receiving and recognizing unit 1 , the normally open switch module 3 and the brake driving unit 2 .

[0035] Optionally, the closed circuit also includes a first normally closed switch module 5.

[0036] Specifically, the first normally closed switch module 5 is connected in series in the closed circuit. When the first normally closed switch module 5 is operated to be opened, the closed circuit can be opened, and the power supply unit 4 stops supplying power to the entire emergency braking system, so that the emergency braking system can be disabled.

[0037] Optionally, the first normally closed switch module 5 is a push-button normally closed switch.

[0038] Specifically, the push-button normally closed switch can be arranged in a position in the vehicle that is convenient for the driver to operate. When the driver wants to disable the emergency braking system, he only needs to press the push-button normally closed switch.

[0039] Optionally, the closed circuit also includes a second normally closed switch module 6.

[0040] Specifically, the second normally closed switch module 6 is also connected in series in the closed circuit. When the second normally closed switch module 6 is operated to be disconnected, the closed circuit can also be disconnected, and the power supply unit 4 stops supplying power to the entire emergency braking system, so that the emergency braking system can also be disabled. In this embodiment, the second normally closed switch module 6 is arranged in a position in the car that the driver and passengers cannot operate. If the second normally closed switch is operated when the car leaves the factory, it is equivalent to that the car does not have this configuration, which serves as the difference in high and low configurations of the car models.

[0041] Further, such as Figure 1 As shown, in this embodiment, the power supply unit 4, the first normally closed switch module 5, the voice reception recognition unit 1, the normally open switch module 3, the brake drive unit 2 and the second normally closed switch module 6 are electrically connected to form a closed circuit; the closed circuit is powered by the power supply unit 4, and the power supply unit 4 can use a battery.

[0042] Optionally, the speech reception recognition unit 1 includes a speech reception recognizer.

[0043] Specifically, the voice receiving and recognizing device is arranged on the center console in the car.

[0044] Optionally, two voice receiving and recognition units 1 are provided, wherein one voice receiving and recognition unit 1 is provided on the center console of the automobile, and the other voice receiving and recognition unit 1 is provided on the outside of the rear of the automobile.

[0045] Specifically, Figure 2 and Figure 3 As shown, two voice receiving and recognition units 1 are installed, one inside the car and the other outside the car. No matter whether a person is inside or outside the car, he can perform emergency braking of the car by issuing a set voice message; when the driver is unable to step on the brake pedal in time due to fatigue, distraction, etc., resulting in a dangerous emergency situation, the occupants in the car can perform emergency braking of the car by issuing a set voice message; when the driver forgets to pull the handbrake due to negligence and causes the car to slip, the driver outside the car can also perform emergency braking of the car by issuing a set voice message to avoid losses and dangers.

[0046] Optionally, the power supply unit 4 is a battery of the vehicle.

[0047] The utility model also provides a car, which comprises the emergency braking system.

[0048] In summary, the emergency braking system provided by the utility model is equipped with a voice receiving and recognizing device, and a set voice signal for activating the emergency braking system can be pre-set, such as "Hello, brake", "emergency brake", etc. Only this set voice signal can enable the processing module to control the brake drive unit 2 to work. In this embodiment, the brake drive unit 2 includes a telescopic component, and the telescopic end of the telescopic component is connected to the brake pipe of the brake device 7, and the brake pipe can be pulled by the telescopic component to brake the car; other voice signals are invalid for it, so that the system can be avoided from being started by mistake. The system uses the battery of the car as a power source. When the voice receiving and recognizing device receives and recognizes the set voice information, the processing module controls the normally open contact of the normally open switch module 3 to close, the circuit is closed, the telescopic component works, and the car brakes and decelerates. The logic operation of the emergency braking system is simple, the response time is short, and it can be started inside and outside the car, which can effectively avoid driving safety problems in emergency situations; at the same time, it is low in cost and has a wide range of applications.

[0049] The above description of various embodiments of the utility model is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
