Description
Technical Field
Embodiments of the present disclosure relate generally to the technical field of vehicles, and more particularly, to a control method, a control apparatus, and a vehicle for a vehicle.
Background
Currently, with the continuous development of vehicle technologies, more and more vehicles adopt an auxiliary driving system. For example, a camera-based Advanced Driving Assistance (ADAS) system detects the surroundings and targets of a vehicle, and implements control and alarm functions for the vehicle through analysis and judgment. The ADAS system is greatly affected by light intensity, and the system cannot properly collect images under the conditions of strong light and weak light, so that the system performance is reduced, and the safety is correspondingly reduced. For example, in the evening, sunlight is horizontally irradiated to a camera in the ADAS system, the camera is "blind" due to strong light, and the driving assistance function cannot be normally performed, so that a potential hazard (for example, a front collision or the like) occurs.

Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.
In describing embodiments of the present disclosure, the terms "include" and its derivatives should be interpreted as being inclusive, i.e., "including but not limited to. The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first," "second," and the like may refer to different or the same object. Other explicit and implicit definitions are also possible below.
Fig. 1 shows an architectural schematic of a driving assistance system 100 in which embodiments of the present disclosure may be implemented. It should be understood that the structure and function of the driver assistance system 100 as shown in fig. 1 are for illustrative purposes only and do not imply any limitation on the scope of the present disclosure. Embodiments of the present disclosure may be implemented in different structures and/or architectures.
As shown in fig. 1, the driver assistance system 100 includes a sensing component 110, a control component 120, an execution component 130, and an interface component 140. The various components communicate with each other via connections 150-1, 150-2, and 150-3 (collectively referred to as "connections 150"), which connections 150 may be can lines or hard lines.
Fig. 2 further illustrates a schematic diagram of the sensing component 110. The perception component 110 includes an image acquisition unit, such as a camera 210. The camera 210 captures video or image signals of the vehicle surroundings for transmission to the control component 120 for further processing.
The control component 120 controls the vehicle in real time, such as braking, accelerating or decelerating, via the execution component 130, while communicating relevant information, such as visually or audibly, to the driver or passenger via the interface component 140, based on vehicle dynamics and information captured by the camera 210.
The current driving assistance system 100 is greatly affected by the light intensity in the environment where the vehicle is running, for example, in the case of strong light and weak light, the system cannot properly acquire images, so that the system performance is reduced, and the safety is correspondingly reduced.
Embodiments of the present disclosure provide a technical solution for controlling a vehicle, which obtains light intensity information in a vehicle driving environment by adding a light collection module (e.g., as shown in fig. 2, a light sensor 220) to a sensing assembly 110, and adjusts a function of a driving assistance system 100 accordingly based on the information, and timely notifies a driver or a passenger. In this way, potential hazards caused by performance degradation or failure of the camera 210 can be avoided, and the operability of the driver assistance system 100 at different light intensities can be improved, thereby improving safety performance.
Fig. 3 shows a flowchart of a control method for a vehicle according to an embodiment of the present disclosure. For example, the method 300 may be performed by the control component 120 as shown in FIG. 1. The actions involved in method 300 are described below in conjunction with fig. 1 and 2. It should be understood that method 300 may also include additional acts not shown and/or may omit acts shown, and the scope of the present disclosure is not limited in this respect.
At block 310, the control component 120 may obtain light intensity information around the vehicle. Light intensity information is collected by the light sensor 220 and transmitted to the control assembly, for example, in a real-time manner. The real-time manner can enable the driving assistance system 100 to timely sense the light intensity change in the surrounding environment and quickly react.
At block 320, the control component 120 may determine an operating state of the driver assistance system 100 based on the acquired light intensity information. In some embodiments, the control component 120 determines a light intensity value around the vehicle from the light intensity information and compares the light intensity value to a predetermined intensity interval.
If it is determined that the light intensity value is outside the predetermined intensity interval, the control component 120 determines that the operation state is a suppression state, wherein the suppression state is a state in which the function of the driving assistance system 100 is limited. In this way, the driver assistance functionality of the driver assistance system 100 is limited when the light is too strong or too weak to avoid making incorrect driving decisions, such as acceleration or deceleration, due to the camera 220 being "blind".
At block 330, if the control component 120 determines that the operating state is a suppressed state, a warning message is output. In some embodiments, the control component 120 may provide the warning information through a display device or an audio device in the interface component 140. In this way the driver is alerted to more manual intervention in the driving of the vehicle.
Fig. 4 shows a flowchart of a control method for a vehicle according to another embodiment of the present disclosure. For example, the method 400 may be performed by the control component 120 as shown in FIG. 1. The actions involved in method 400 are described below in conjunction with fig. 1 and 2. It should be understood that method 400 may also include additional acts not shown and/or may omit acts shown, and the scope of the present disclosure is not limited in this respect.
At block 410, the control component 120 filters the acquired light intensity information, such as mean filtering, kalman filtering, to improve the quality of the acquired information. At block 420, the control component 120 detects a range of filtered light intensity information based on hardware characteristics of the light sensor 220. This detection may be effective to indicate the operating state of the light sensor 220.
If the value of the light intensity information is outside the performance range of the light sensor 220, indicating that the light sensor 220 is malfunctioning, the method 400 proceeds to block 460. At block 460, the control component 120 suppresses the driving assistance function of the executive component 130 and outputs a warning message to the driver or passenger through the interface component 140. If the value of the light intensity information is within the performance range of the light sensor 220, indicating that the light sensor 220 is functioning properly, the method 400 proceeds to block 440.
At block 440, the control component 120 compares the light intensity value obtained from the light intensity information to a predetermined intensity interval. It is assumed that the predetermined intensity interval is defined by an upper limit value and a lower limit value, which are determined according to an operating light intensity range of the camera 210. When the light intensity value is higher than the upper limit value, the light intensity is determined as class a (strong light); when the light intensity value is lower than the lower limit value, the light intensity is determined as class C (low light/dark light); when the light intensity value falls within the intensity interval, the light intensity is determined as B-class (working region). If the light intensity is determined to be class A or class C, the method 400 proceeds to block 460. If the light intensity is determined to be in the B-class, the driving assist function is normal, and the warning information is not output.
According to a second aspect of the present disclosure, a control apparatus for a vehicle is provided. The control apparatus includes: the light sensor 220 is configured to acquire light intensity information around the vehicle. The control device is configured to: based on the acquired light intensity information, the operating state of the driver assistance system 100 of the vehicle is determined. The control device outputs warning information if it is determined that the operating state is the suppression state.

These program codes may be provided to a processor or controller of a general purpose computer, special purpose computer, or other programmable data processing apparatus, such that the program codes, when executed by the processor or controller, cause the functions/operations specified in the flowchart and/or block diagram to be performed. The program code may execute entirely on the machine, partly on the machine, as a stand-alone software package partly on the machine and partly on a remote machine or entirely on the remote machine or server.
