Example one

As shown in fig. 1, the present embodiment provides a safety control method, which is applied to a vehicle, which may be a fuel vehicle, a pure electric vehicle, or a hybrid vehicle, and is not limited herein. The safety control method comprises the following steps:

step 110, locking a vehicle gear based on a vehicle wake-up signal;

step 120, acquiring real-time image information of the surrounding environment of the vehicle;

step 130, judging whether the surrounding environment of the vehicle has potential safety hazards or not according to the real-time image information;

step 140, when potential safety hazards exist in the surrounding environment of the vehicle, sending an alarm prompt to remind a driver of safety inspection;

and 150, when the potential safety hazard does not exist in the surrounding environment of the vehicle or is eliminated, unlocking the gear of the vehicle and returning the control right of the vehicle to the driver.

In the above embodiment, when the vehicle receives the wake-up signal, the vehicle will be woken up, and at this time, the gear of the vehicle is immediately locked, so that the driver cannot engage the gear and the vehicle cannot move. And then, acquiring real-time image information of the surrounding environment of the vehicle, and judging whether the surrounding environment of the vehicle has potential safety hazards or not according to the real-time image information. When potential safety hazards exist, an alarm is given out to remind a driver of safety inspection before driving, and the risk of accidents is reduced; when no potential safety hazard exists or the potential safety hazard is eliminated, the gears of the vehicle are unlocked under the condition of ensuring the environmental safety, the control right of the vehicle is returned to the driver, and at the moment, the driver can engage in the gear to drive the vehicle. Through the design, even if the driver has no habit of safety inspection before the vehicle is started or the safety inspection of the driver is not in place, the risk of safety accidents occurring when the vehicle is started can be reduced.

The individual steps of the safety control method are explained in detail below, as follows:

in step 110, the vehicle gear is locked based on the vehicle wake-up signal. It can be understood that the vehicle wake-up signal is sent by the action of the driver starting the vehicle, and based on the signal, the vehicle gear is locked, so that the driver cannot shift the gear adjusting rod, and the vehicle cannot go forward or backward, that is, the control right of the driver on the vehicle is temporarily deprived.

In step 120, real-time image information of the surroundings of the vehicle may be acquired by a camera mounted on the vehicle. The real-time image information comprises vehicle bottom real-time image information and vehicle body periphery real-time image information, so that the real-time image information of the surrounding environment of the vehicle can be comprehensively known.

In step 130, the method for determining whether the vehicle surrounding environment has a potential safety hazard according to the real-time image information includes:

step 131, identifying real-time image information, and analyzing whether an obstacle exists in the real-time image information;

it should be noted that the present embodiment may adopt an SOC processor

The real-time image information acquired by 41 is subjected to image processing, and it is recognized whether or not an obstacle exists in the real-time image information. The obstacle in this embodiment is mainly an obstacle that affects the traveling of the vehicle, such as a person, an animal, or another vehicle. The conventional image recognition technology recognizes the obstacles in a conventional manner, and details are not repeated herein;

step 132, if the real-time image information includes an obstacle, it is determined that the vehicle surrounding environment has a potential safety hazard, or if the real-time image information includes no obstacle, it is determined that the vehicle surrounding environment does not have a potential safety hazard.

In step 140, when the surrounding environment of the vehicle has a potential safety hazard, an alarm prompt is sent out to prompt the driver to perform safety inspection.

It will be appreciated that since the vehicle gear is locked in step 110, when there is a safety hazard around the vehicle, the driver is not only unable to control the vehicle to move forward or backward, but also receives an alarm prompt, which may be issued by the speaker 46 in the vehicle. The design is more humanized, so that a driver can clearly know that the reason why the vehicle cannot be in gear is because potential safety hazards exist around the vehicle. It should be noted that, in step 110 in this embodiment, real-time image information of the surrounding environment of the vehicle is acquired. Therefore, when the potential safety hazard exists in the surrounding environment of the vehicle, whether the potential safety hazard exists in the surrounding environment of the vehicle is judged according to the real-time image information all the time, and the judgment operation is stopped until the potential safety hazard is eliminated.

In step 150, when the surrounding environment of the vehicle has no potential safety hazard or the potential safety hazard is eliminated, the gear of the vehicle is unlocked, and the control right of the vehicle is returned to the driver.

It can be understood that when no potential safety hazard exists or the potential safety hazard is eliminated, the safety of the vehicle during starting can be guaranteed, the gear of the vehicle is unlocked at the moment, and a driver can shift into the gear to move forwards or backwards.

Example two

As shown in fig. 2, the present embodiment provides a safety control method, which is applied to a vehicle, where the vehicle may be a fuel vehicle, a pure electric vehicle, or a hybrid vehicle, and is not limited herein. The safety control method comprises the following steps:

step 210, locking a vehicle gear based on a vehicle wake-up signal;

step 220, acquiring real-time image information of the surrounding environment of the vehicle;

step 230, uploading the real-time image information to a display screen 45 in the vehicle cabin for the reference of a driver;

step 240, when potential safety hazards exist in the surrounding environment of the vehicle, sending an alarm prompt to prompt a driver to perform safety inspection;

step 250, when the surrounding environment of the vehicle has no potential safety hazard or the potential safety hazard is eliminated, unlocking the gear of the vehicle, and returning the control right of the vehicle to the driver;

step 260, when the vehicle is in the driving process, acquiring the real-time driving speed of the vehicle;

and 270, when the real-time driving speed is greater than a preset vehicle speed threshold, suspending obtaining the real-time image information of the surrounding environment of the vehicle.

The method provided by the embodiment has all the advantages of the first embodiment, and compared with the method of the first embodiment, the method of the embodiment has

more steps

230, 260 and 270.

In step 230, after the real-time image information is uploaded to the display screen 45 in the vehicle cabin, the driver can visually observe the surrounding situation of the vehicle, so that the driver can conveniently eliminate potential safety hazards. In addition, in the driving process of the vehicle, the driver can observe the situation around the vehicle, so that the driving can be assisted, and the occurrence of driving accidents is reduced.

In step 270, when the real-time driving speed is greater than the preset vehicle speed threshold, the acquisition of the real-time image information of the surrounding environment of the vehicle is suspended.

It should be noted that the acquisition rate of the conventional camera and the processing speed of image processing are limited, and when the driving speed is too high, the camera cannot acquire clear or complete image information. At the moment, the significance of collecting the image information is not large, and the information processing capacity of the whole vehicle is consumed. Therefore, when the real-time driving speed is greater than the preset vehicle speed threshold value, the real-time image information of the surrounding environment of the vehicle is temporarily stopped to be obtained, and when the real-time driving speed is less than or equal to the preset vehicle speed threshold value, the real-time image information is obtained, so that the design is more scientific and reasonable. The vehicle speed threshold in this embodiment may be specifically set by the performance of the camera on the vehicle, and may be set to 30Km/h, for example, that the camera operates only in a low-speed driving state where the real-time driving speed is less than 30 Km/h.

In conclusion, the safety control method in the embodiment can not only ensure the safety of the vehicle when the vehicle is started, but also assist the driver to know the surrounding environment more intuitively when the vehicle is driven at a low speed, so that the risk of driving accidents is reduced.
