Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to an intelligent driving control method, system, and vehicle based on controller fault detection. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] With the continuous development of automotive electronics technology, automobiles are gradually becoming the primary means of transportation. Autonomous driving systems are being used more and more in vehicles, and consumers are increasingly expecting more from autonomous driving functions. At the same time, this also places higher demands on the safety of autonomous driving. When the driver activates the autonomous driving function, their control over the vehicle decreases. If a malfunction occurs in the autonomous driving controller and is not detected in time, the vehicle may exhibit unexpected behavior, leading to loss of control, injury, and even death. Therefore, as the core hub of the autonomous driving system, confirming the normal operating status of the autonomous driving controller is crucial.

[0004] Currently, various detection devices are set up to detect the status of the autonomous driving intelligent driving controller. When an abnormality is detected in the status of the autonomous driving intelligent driving controller, the vehicle is controlled to enter a safe driving state.

[0005] The current intelligent driving control method only considers whether the intelligent driving controller itself is in an abnormal state, without considering the impact of the detection device's state on the intelligent driving controller's detection results. This leads to inaccurate judgment of abnormal intelligent driving controller states, and consequently, it cannot achieve timely and effective control of the vehicle. Summary of the Invention

Figure 2 As shown, the intelligent driving system includes a primary detection module, an intermediate detection module, and an intelligent driving controller.

[0044] The primary and intermediate detection modules are both connected to the intelligent driving controller, which is used to control the intelligent driving of the vehicle. The intelligent driving controller includes a power module, a communication module, a storage module, a sensor serializer, a performance computing unit (SOC), and a real-time computing unit (MCU).

[0045] The system comprises the following components: a power module for supplying power to the intelligent driving controller; a communication module for internal communication with the intelligent driving controller and other components; a storage module for storing data acquired by sensors; a sensor serializer for deserializing and serializing signals from sensors such as cameras and ultrasonic signals; a System-on-Chips (SoC) for processing video images acquired by sensors such as cameras and ultrasonic signals, detecting target information, and outputting it; and a Microcontroller (MCU) for performing driving calculations based on the target information detected by the SoC, determining a driving control scheme, and then controlling the vehicle according to the driving control scheme.

[0050] The intelligent driving control method based on controller fault detection provided in this application embodiment, such as... Figure 1 As shown, it includes:

[0051] During intelligent driving, the status of the intelligent driving controller is obtained through the intelligent driving controller detection module;

[0052] When the intelligent driving controller is in an abnormal state, it controls the vehicle to enter a safe driving state.

[0053] When the intelligent driving controller is in normal condition, the status of the intelligent driving controller detection module is monitored by the monitoring and detection module.

[0054] When the intelligent driving controller detects an abnormal state in the module, it controls the vehicle to enter a safe driving state.

[0055] When the intelligent driving controller detects the module's status is normal, the intelligent driving controller monitors the detection module's status.

[0056] When the monitoring and detection module is in an abnormal state, control the vehicle to enter a safe driving state.

[0057] Among them, controlling the vehicle to enter a safe driving state means controlling the vehicle to exit the intelligent driving state or controlling the vehicle to downgrade its intelligent driving.

[0058] In summary, the intelligent driving control method based on controller fault detection provided in this application can achieve comprehensive anomaly detection of the intelligent driving controller and various detection modules in the intelligent driving system, thereby enabling timely and accurate detection of anomalies in the intelligent driving system, and then controlling the vehicle based on the detected anomalies to ensure vehicle driving safety.

[0059] The monitoring of the status of the intelligent driving controller detection module and the monitoring detection module in this embodiment can be performed in the following way: acquiring the input signals and output signals of the detection module;

[0060] When the output signal parameters meet the set requirements and the input signal and output signal are consistent, the detection module is considered to be in normal condition.

[0061] When the output signal parameters do not meet the set requirements, or when the input signal and output signal are inconsistent, the detection module is deemed to be in an abnormal state.

[0062] The intelligent driving controller status obtained by the intelligent driving controller detection module in this embodiment includes: the power module status, communication module status, sensor serializer status, storage module status, performance computing unit status, and execution computing unit status in the intelligent driving controller.

[0063] Specifically, when the power module status, communication module status, sensor serializer status, storage module status, performance computing unit status, and implementation computing unit status are all normal, the intelligent driving controller is determined to be in normal status.

[0064] When one or more of the following states are abnormal: power module state, communication module state, sensor serializer state, storage module state, performance computing unit state, and implementation computing unit state, the intelligent driving controller is determined to be in an abnormal state.

[0065] In this embodiment, the power module status is characterized by the connector voltage signal of the power module; the communication module status is characterized by the CAN signal transmission and Ethernet signal transmission capabilities of the communication module; the sensor serializer status is characterized by the signal deserialization and signal serialization functions; the storage module status is characterized by the file reading and storage functions of the storage module; the performance computing unit status is characterized by the video image processing operation function and target information monitoring and output function of the performance computing unit; and the real-time computing unit status is characterized by the driving computing function and driving control function of the real-time computing unit.

[0066] When the connector voltage signal of the power module is abnormal, the power module is determined to be in an abnormal state; when the CAN signal transmission and Ethernet signal transmission capabilities of the communication module are abnormal, the communication module is determined to be in an abnormal state; when the signal deserialization and signal serialization functions of the sensor are abnormal, the sensor serializer is determined to be in an abnormal state; when the file reading and storage functions of the storage module are abnormal, the storage module is determined to be in an abnormal state; when the video image processing operation function and target information monitoring and output function of the performance computing unit are abnormal, the performance computing unit is determined to be in an abnormal state; when the driving computing function and driving control function of the real-time computing unit are abnormal, the real-time computing unit is determined to be in an abnormal state.

[0067] In this embodiment of the application, when an abnormality is detected in the intelligent driving controller or various detection modules, in addition to controlling the vehicle to enter a safe driving state, a fault signal is also issued to remind the driver.

[0068] Specifically, the intelligent driving control method based on controller fault detection provided in this application embodiment includes the following steps: After the intelligent driving system is activated, during normal operation of the intelligent driving system, an independent power detection module detects the connector voltage signal of the power module in the intelligent driving controller. When the connector voltage signal of the power module is abnormal, a fault signal is issued and the vehicle is controlled to enter a safe driving state. An independent communication detection module detects the signal transmission capability of the CAN signal transmission level and Ethernet transmission capability of the communication module in the intelligent driving controller. When the signal transmission capability of the CAN signal transmission level and Ethernet transmission capability is abnormal, a fault signal is issued and the vehicle is controlled to enter a safe driving state. An independent serializer detection module detects the signal deserialization and signal serialization functions of sensors such as cameras and ultrasonic signals in the intelligent driving controller. When the signal deserialization and signal serialization functions are abnormal, a fault signal is issued and the vehicle is controlled to enter a safe driving state. An independent storage detection module detects the read and store functions of the SOC storage files in the intelligent driving controller. When the read and store functions are abnormal, a fault signal is issued and the vehicle is controlled to enter a safe driving state. An independent SOC detection module monitors the video image processing and target information detection and output functions of the Performance Computing Unit (SOC) in the intelligent driving controller. When any of these functions malfunctions, a fault signal is issued, and the vehicle is controlled to enter a safe driving state. Similarly, an independent MCU detection module monitors the driving calculation and control functions of the Real-Time Computing Unit (MCU) in the intelligent driving controller. When either function malfunctions, a fault signal is issued, and the vehicle is controlled to enter a safe driving state. Because these six independent detection modules may malfunction and fail to issue corresponding fault signals, an independent monitoring detection module monitors them. When any of these six modules malfunctions, a fault signal is issued, and the vehicle is controlled to enter a safe driving state. This independent monitoring detection module is also monitored by the intelligent driving controller. When this module malfunctions, a fault signal is issued, and the vehicle is controlled to enter a safe driving state. This creates a loop to ensure vehicle driving safety.
