The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of an automobile control device according to the present invention.
As shown in fig. 1, in this embodiment, the vehicle control apparatus includes a main control module 100, a forward view control module 200, and a look-around control module 300, wherein the main control module 100 is connected to the forward view control module 200 and the look-around control module 300, respectively.
The forward looking control module 200 is configured to obtain forward looking visual information and transmit the forward looking visual information to the main control module 100.
It should be noted that the forward looking control module 200 may include a forward looking image chip, which can parse the received image to obtain information in the image, so as to obtain forward looking visual information. Generally, a forward-looking camera is matched with the forward-looking image chip and is used for shooting an image of a scene in front of a vehicle, so that a forward-looking image is provided for the forward-looking image chip.
It should be noted that the forward-looking visual information generally includes road information or environmental information in a longer distance in front of the vehicle, such as a lane line, a forward vehicle distance, or an obstacle, and may also include other information, which is not limited in this embodiment.
It can be understood that the forward-looking visual information is mainly used for intelligent driving control, and the main control module 100 can execute various driving strategies according to the forward-looking visual information. For example, when an obstacle is detected ahead, deceleration control is performed in advance.
The all-round looking control module 300 is configured to acquire all-round looking visual information and transmit the all-round looking visual information to the main control module 100.
It should be noted that the all-round control module 300 may include an all-round vision chip, and the all-round vision chip may be capable of analyzing the received image to obtain information in the image, so as to obtain the forward-looking visual information. Generally, a panoramic image chip is matched with a panoramic camera, and a forward-looking camera shoots images of scenes around a vehicle to provide a panoramic image for the panoramic image chip. In a specific implementation, the look-around vision chip may be the same type of chip as the look-ahead image chip.
It should be noted that the all-round visual information generally includes environmental information in a relatively close range around the vehicle, such as lane lines or obstacles, and may also include other information, which is not limited in this embodiment.
It can be understood that the look-around visual information is mainly used for intelligent parking control, and the master control module 100 can execute a parking control strategy according to the look-around visual information. For example, the vehicle is controlled to enter the parking space by identifying the parking space information through identifying the lane line on the road surface; meanwhile, the parking route is adjusted according to the barrier information in the scene, and collision is avoided.
The main control module 100 is configured to obtain environmental sound wave information.
It should be noted that, in order to more accurately acquire the distance information of the object in the scene, the main control module 100 can also acquire the ambient sound wave information. The main control module 100 may include a main control chip, and the main control chip may analyze the received sound wave signal to obtain the environmental sound wave information. The acoustic signal may be an ultrasonic signal or a radar signal. The ambient acoustic information typically includes distance information, such as the presence of an object 5 meters in front of the vehicle.
The main control module 100 is further configured to generate a driving control signal according to the forward-looking visual information and the environmental acoustic information, and control the vehicle to perform an auxiliary driving operation according to the driving control signal.
It is understood that in the intelligent driving control, the main reference information is the forward looking visual information and the ambient sound wave information. And the main control chip analyzes the forward-looking visual information and the environmental sound wave information, judges the driving state and formulates a driving strategy.
It should be noted that the driving control signal generally includes a driving signal of the actuator, such as a brake pad driving signal, a motor speed adjusting signal, and the like. The driving chip determines the environmental information in front of the vehicle according to the forward-looking visual information and the environmental sound wave information, and generates a corresponding driving control signal according to a preset control strategy. If the vehicle is identified to be 10 meters ahead of the vehicle, generating deceleration control information; and when the vehicle is identified to be pressed when the vehicle is in straight line running, generating an alarm signal and the like. The driving chip sends the driving control signal to the corresponding actuating mechanism to control the automobile to execute the auxiliary driving operation.
The main control module 100 is further configured to generate a parking control signal according to the look-around visual information and the environmental sound wave information, and control the automobile to perform a parking operation according to the parking control signal.
It is understood that, in the intelligent parking control, the main reference information is the all-round visual information and the environmental sound wave information. The master control chip analyzes the look-around visual information and the environmental sound wave information to obtain the environmental information around the vehicle, so that a parking strategy is formulated.
The parking control signal includes a driving signal of the actuator, a steering driving signal of the steering mechanism, a motor speed adjusting signal, and the like, the driver chip determines the surrounding environment information of the vehicle according to the visual information and the environmental sound information, and generates a corresponding parking control signal according to a preset control strategy. If a parking space 5 meters behind the vehicle is detected, controlling the vehicle to back up; and in the process of backing, when the obstacle existing at the left rear part is detected, controlling the vehicle to enter the parking space from the right rear part.
It should be noted that the master control module 100 is compatible with driving control and parking control, and the master control module 100 can perform resource allocation according to the vehicle state. For example, the vehicle speed is obtained, and the driving control function is executed under the high-speed working condition. At low speed, the parking function is performed. When the all-round vision chip and the forward vision chip are in a standby state, the all-round vision chip and the forward vision chip can be used as a safety redundancy backup and safety monitoring mechanism to monitor whether the main chip fails or not, and the all-round vision chip and the forward vision chip can be used as a standby chip after the main chip fails.
It should be noted that, when the driving control is executed, the look-around visual information can also be called through the parking control channel; when parking control is executed, forward-looking visual information can be usually called through driving control so as to realize resource sharing. The intelligent parking and intelligent driving function arbitration mechanism is performed by a preset arbitration mechanism in a main control chip, for example, when a vehicle is detected to exceed a preset value, the intelligent driving function is started, control resources are centralized in driving control, and at the moment, part of parking functions can be closed; when the vehicle is in a parking mode or the vehicle speed is lower than a preset value, the intelligent parking function is started, control resources are centralized in the parking space control, and at the moment, part of the driving control functions can be closed.
In the embodiment, the automobile control device is formed by arranging a main control module, a forward-looking control module and a look-around control module; the forward-looking control module acquires forward-looking visual information; the around vision visual information is obtained through the around vision control module; the main control module acquires environmental sound wave information and controls the automobile to execute auxiliary driving operation by combining with the forward-looking visual information; or, the automobile is controlled to execute the parking operation by combining the look-around visual information.
