[0057] The present invention is developed based on the vehicle intelligent control driving system and can be applied to different intelligent driving chip architectures. Specifically, it can be applied to intelligent driving systems developed based on cabin-driver integration solutions and non-cabin-driver integration solutions.

[0058] The cabin-driver integrated solution has developed rapidly in recent years, thanks to the substantial improvement in computing power of chip manufacturers. With the evolution of automobile functions, the improvement of electrification level and the advancement of autonomous driving, the number of ECUs continues to grow. The traditional distributed electronic and electrical architecture with single-chip microcomputers as the core can no longer meet the development needs of future smart car products. In addition, traditional automobile ECUs also adopt a distributed architecture. The distributed architecture is also reflected in the inability to share computing power between controllers. When processing similar functional logic, computing power resources are difficult to achieve optimal allocation, resulting in resource waste. At present, the electronic and electrical architecture continues to evolve towards domain concentration, cross-domain integration, and centralization. In order to reduce the cost of the entire vehicle, domain controllers came into being. The driving-parking integrated domain controller is one of them. The cabin-driver integrated solution is developed based on the cabin-parking integrated solution and the driving-parking integrated solution. In the domain controller architecture stage, the cabin-parking integrated solution and the driving-parking integrated solution are both transitional solutions. With the rapid development in recent years, the cabin-driver integrated solution has further improved the intelligence level of the vehicle.

[0059] The following takes the cockpit integration solution as an example to explain this solution in detail. The essence of the so-called cockpit integration solution is to integrate the cockpit domain and the intelligent driving domain across domains. The implementation of its functions is mainly based on the cockpit-driver integrated domain controller (Driver Information Head Unit, referred to as DHU). The cockpit domain includes the cockpit control module. The existing human-machine interface (Human Machine Interface, referred to as HMI) can be regarded as a type of cockpit control module. The HMI (car human-machine interface) mainly realizes the human-machine interaction function in the cockpit. The intelligent driving domain includes the intelligent assisted driving control module. The existing common intelligent driving assistance system (Advanced Driver Assistance System, referred to as ADAS) can be regarded as the most widely used type of intelligent assisted driving control module. The cockpit control module and the intelligent assisted driving control module are both integrated on a SOC chip of the vehicle. The SOC chip integrated with the cockpit control module and the intelligent assisted driving control module can be regarded as the DHU (cabin-driver integrated domain controller); the DHU (cabin-driver integrated domain controller) also includes an MCU chip, which is extremely stable, and a body control module (Body Control Module). The MCU chip in the DHU (cabin-drive integrated domain controller) sends control instructions to the BCM (body control module) or VACM (alarm control module), and controls the flashing of the alarm light or the sound of the alarm through the gateway interface of the TCAM.Under normal circumstances, except in extreme cases, the MCU chip in the DHU (Dock-Drive Integrated Domain Controller) will not have any problems. However, the intelligent driving module and the intelligent interaction module are integrated on the SOC chip in the DHU (Dock-Drive Integrated Domain Controller). Due to limitations in computing power, heat generation, and other issues, the SOC chip in the DHU (Dock-Drive Integrated Domain Controller) may experience instability. This is generally manifested in failure of the cockpit control module, such as a black screen on the intelligent interaction screen in the cockpit and failure of the intelligent assisted driving control module. Therefore, if there is a problem with the SOC chip in the DHU (Dock-Drive Integrated Domain Controller), the driver may not be able to promptly understand the vehicle's intelligent driving status during normal driving. For example, the intelligent interaction screen in the cockpit is black, and the driver cannot know whether the ADAS is functioning properly. For example, if the intelligent interaction screen in the cockpit is functioning properly but the ADAS (intelligent driving assistance system) is already in a faulty state, if the driver continues to use the vehicle's intelligent driving function without prior judgment, it may cause certain safety hazards. Therefore, a control method for an intelligent assisted driving mode is proposed, which can be executed according to the following control method:

[0060] The premise for executing this control method is that the vehicle is driving in an intelligent assisted driving mode. Taking ADAS (intelligent driving assistance system) as an example, the vehicle is driving in ADAS (intelligent driving assistance system) on mode;

[0061] Step S101: Acquire the working status of the cockpit control module and determine whether there is any abnormality in the cockpit control module.

[0062] In some embodiments, a code stream may be reserved in the vehicle's SOC chip in advance to obtain whether the cabin control module in the SOC chip is normal, so that the SOC chip has instructions for knowing the working status of the cabin control module, and then judge whether there is any abnormality in the working status of the cabin control module in the SOC chip.

[0063] The cockpit control module working status obtained in step S101 is processed according to the following step S102.

[0064] Step S102: When an abnormality occurs in the cockpit control module, an alarm message is issued through the intelligent assisted driving control module and / or the body control module (BCM) and / or the alarm control module (VACM) to prompt the driver to take over the vehicle; and the cockpit control module is restarted according to preset rules.

[0065] In one embodiment, when an abnormality is detected in the vehicle's cabin control module, an alarm message is issued through one or more of the intelligent assisted driving control module, the body control module (BCM), and the alarm control module (VACM) to prompt the driver to take over the vehicle and restart the vehicle's cabin control module.

[0066] In one embodiment, the body control module (BCM) and the alarm control module (VACM) rely on the vehicle's MCU chip for implementation, and the intelligent assisted driving control module relies on the SOC chip for implementation. The code stream can be preset in the MCU chip or SOC chip in the DHU (cabin-driver integrated domain controller). Once the above situation occurs, corresponding instructions are issued to control the screen or speaker in the vehicle to issue an alarm message, or the body control module (BCM) sends a vehicle control signal to control the vehicle steering wheel to shake or apply the brakes to the vehicle to remind the driver.

[0067] In some embodiments, the step of executing the warning signal includes controlling one or more of brake application, sound alarm, and steering wheel vibration.

[0068] In some embodiments, the vehicle can be controlled by the body control module (BCM) to remind the driver by controlling the brake tap, by vibrating the vehicle's steering wheel, or by controlling the speaker to send an alarm signal through the alarm control module (VACM). Any one or more of the above three methods can serve as a reminder.

[0069] In one embodiment, if the driver still does not take over, in the step of issuing an alarm message through the intelligent assisted driving control module and / or the body control module (BCM) and / or the alarm control module (VACM), the vehicle is controlled to send a set number of alarm messages within a set time.

[0070] In one embodiment, the set time is 3 seconds to 10 seconds, and the set number of times is 1 to 4 times. In some embodiments, the number of times the alarm information is sent to the driver is 2 times. Generally, a maximum of two times is enough to serve as a reminder.

[0071] In one embodiment, taking the alarm sound as an example, a voice alarm message can be made in the MCU chip in the DHU (cabin-driver integrated domain controller), which has a different control circuit from the SOC chip in the DHU (cabin-driver integrated domain controller) to ensure that the driver can be notified to take over the vehicle when the cockpit control module is stuck. A braking point braking strategy or a steering wheel vibration strategy and an alarm mechanism of a voice notification of "please take over the vehicle" can also be added.

[0072] In one embodiment, in the above-mentioned step S102, when there is an abnormality in the cockpit control module, the step of issuing an alarm message through the intelligent assisted driving control module, the body control module (BCM) or the alarm control module (VACM) to prompt the driver to take over the vehicle includes: determining whether the intelligent assisted driving control module is available.

[0073] In one embodiment, a code stream may be reserved in the SOC chip of the DHU (cabin-driver integrated domain controller) in advance to obtain whether the intelligent assisted driving control module is normal, so that the SOC chip of the DHU (cabin-driver integrated domain controller) has instructions for knowing the working status of the intelligent assisted driving control module, and then judge whether the working status of the cabin control module in the SOC chip in the DHU (cabin-driver integrated domain controller) is abnormal.

[0074] In actual application, there are two situations:

[0075] Scenario 1: When it is detected that the intelligent assisted driving control module is available, the warning information can be issued by the intelligent assisted driving control module.

[0076] Scenario 2: When the intelligent assisted driving control module is unavailable, the warning information can be issued through the body control module and / or the alarm control module.

[0077] In one embodiment, in step S102, restarting the cockpit control module is performed according to the following preset rules. When executing this step, there are the following two situations:

[0078] Including the situation where the intelligent assisted driving control module is available. When the intelligent assisted driving control module is available, the intelligent assisted driving control module is used to determine whether the driver has successfully taken over the vehicle; when the driver successfully takes over the vehicle, the intelligent assisted driving control module is controlled to exit the intelligent assisted driving mode and restart the cockpit control module.

[0079] In one embodiment, the intelligent assisted driving control module determines whether the driver has successfully taken over the vehicle by obtaining one or more vehicle information including the accelerator pedal opening and closing degree, the steering wheel torque, and the brake pedal opening and closing degree, and makes a judgment based on the obtained vehicle information to determine whether the driver has successfully taken over the vehicle. Once the vehicle is successfully taken over by the driver, the intelligent assisted driving control module can be controlled to exit the intelligent driving mode, and a control instruction can be issued to control the cockpit control module to restart.

[0080] In one embodiment, in order to obtain the accelerator pedal opening and closing information, the accelerator pedal opening and closing information can be obtained through the signal acquisition module in the MCU chip, and the accelerator pedal opening and closing information is compared with a preset accelerator opening and closing threshold. When the accelerator pedal opening and closing degree is greater than the accelerator opening and closing degree threshold, it is determined that the driver has taken over the vehicle. In some embodiments, when the accelerator pedal opening and closing degree is greater than 40%, it can be determined that the driver has taken over the vehicle.

[0081] In one embodiment, in order to obtain the brake pedal opening and closing degree information, the brake pedal opening and closing degree information can also be obtained through the signal acquisition module in the MCU chip, and the brake pedal opening and closing degree is compared with a preset brake pedal opening and closing degree threshold. When the brake pedal is greater than the brake pedal threshold, it can be determined that the driver has taken over the vehicle. In some embodiments, when the brake pedal opening and closing degree is greater than 40%, it can be determined that the driver has taken over the vehicle.

[0082] In one embodiment, in order to obtain steering wheel torque information, the steering wheel torque information can also be obtained through the signal acquisition module in the MCU chip, and the steering wheel torque is compared with a preset steering wheel torque threshold. When the steering wheel torque is greater than the steering wheel torque threshold, in some embodiments, when the steering wheel torque is greater than 0.8 Nm, it can be determined that the driver has taken over the vehicle. As long as the driver rotates the steering wheel, the steering wheel torque can be applied to determine that the driver has successfully taken over the vehicle.

[0083] In one embodiment, when the system is actually used, some more special situations may occur, such as the situation where the intelligent assisted driving control module is unavailable: when the MCU chip in the DHU (cabin-driver integrated domain controller) detects that the intelligent assisted driving control module is unavailable, the vehicle movement is controlled according to the pre-stored control strategy, and the cabin control module is controlled to restart.

[0084] In one embodiment, the MCU chip in the DHU (Dock-Drive Integrated Domain Controller) memorizes a lateral trajectory path for 2 to 3 seconds, and a predictive path following module is provided in the MCU chip to support when the intelligent assisted driving control module in the SOC chip in the DHU (Dock-Drive Integrated Domain Controller) is unavailable. The MCU chip in the DHU (Dock-Drive Integrated Domain Controller) can maintain lateral control action for 2 to 3 seconds, thereby supporting the driver to take over safely. When the driver takes over safely, the cockpit control module is controlled to restart.

[0085] To illustrate with reference to a specific embodiment, as shown in FIG2 , in this case, the cockpit control module fails, and the intelligent assisted driving control module is normally available. The SOC chip in the DHU (cabin-driver integrated domain controller) detects the abnormality and sends a restart request and the cause of the fault to the MCU chip in the DHU (cabin-driver integrated domain controller). First, it is determined whether the ADAS (intelligent driving assistance system) is in the on-state. When it is determined that the ADAS (intelligent driving assistance system) is in use, the MCU chip in the DHU (cabin-driver integrated domain controller) determines whether there are abnormalities in the broadcast and display at the same time, that is, whether the above-mentioned cockpit control module is abnormal. When an abnormality occurs, the vehicle emergency call system (Vehicle emergency call) is executed by requesting the vehicle communication terminal (Telematics-Box, referred to as: T-BOX) The system (abbreviated as: ECALL) alarms or requests ESC to perform a braking action, that is, the above-mentioned warning information is issued to inform the driver, and the set time (3 seconds) is used to determine whether the driver has taken over the vehicle. When it is determined that the driver has taken over the vehicle within the set time, the ADAS (intelligent driving assistance system) exits and sends a restart permission instruction, and the DHU (cabin-driver integrated controller) restarts, that is, the above-mentioned cockpit control module restarts; when it is determined that the driver has not successfully taken over the vehicle within the set time, the SOC chip in the DHU (cabin-driver integrated controller) clears: voice alarm, text prompt, light icon, etc. By setting the number of times to request the T-BOX (on-board communication terminal) to execute the ECALL (on-board emergency call system) alarm or periodically requesting the ESC to execute the braking, it is possible to continue to judge whether the vehicle has been successfully taken over. By extending the set time (for example, to 10 seconds) until it is determined that the driver has successfully taken over the vehicle, the sending of the ECALL (on-board emergency call system) alarm request or the braking request is terminated, the ADAS (intelligent driving assistance system) exits and sends a restart permission instruction, and the DHU (cabin-driver integrated controller) is restarted, that is, the cockpit control module in the DHU (cabin-driver integrated controller) is restarted.

[0086] Referring to Figure 3, in this situation, both the cockpit control module and the intelligent assisted driving control module fail. The abnormality is detected by the SOC chip in the DHU (cabin-dock integrated domain controller) and a restart request and the cause of the fault are sent to the MCU chip in the DHU (cabin-dock integrated domain controller). A control signal is directly sent to the SOC chip in the DHU (cabin-dock integrated domain controller), requesting AUDIO (audio) alarm, displaying text, icons, etc., and sending a control signal to the VACM (alarm controller) (through the TCAM gateway interface) to ECALL (on-board emergency call system) alarm. The headlights can also be controlled to flash through the BCM (body control module). The preset response time of the VACM (alarm controller) is set according to actual conditions. In some embodiments, it can be 5 seconds TBD (To Be Determined). The preset response time of the BCM (body control module) is set according to actual conditions. In some embodiments, it can also be 5 seconds TBD.

[0087] There is also a more extreme situation, in which the entire cabin-driver controller (DHU) is hung up. In this case, referring to Figure 4, the SOC chip in the cabin-driver controller (DHU) is overheated or damaged, and the ADAS (intelligent driving assistance system) integrated in the SOC chip directly exits. The MCU chip in the cabin-driver controller (DHU) is also overheated or damaged. The BCM (body control module) can detect the MCU chip signal in the cabin-driver controller (DHU). When a timeout or error occurs, such as a timeout of 5 seconds, the VACM (alarm controller) (through the TCAM gateway interface) can be used to alarm the ECALL (on-board emergency call system), or the BCM (body control module) can be used to control the double flash of the headlights. The preset response time of the VACM (alarm controller) is set according to the actual situation. In some embodiments, it can be 5 seconds TBD. The preset response time of the BCM (body control module) is set according to the actual situation. In some embodiments, it can also be 5 seconds TBD.

[0088] The above are all application examples of the present invention in the cockpit integrated solution. For the non-cockpit integrated solution, the cockpit control module and the intelligent assisted driving control module are independently located on different chips. The cockpit control module is controlled by an independent cockpit controller, and the intelligent assisted driving control module is controlled by an independent intelligent assisted driving controller. The non-cockpit integrated solution can also monitor the independent cockpit controller and the intelligent assisted driving controller according to the above-mentioned control method of the intelligent assisted driving mode to realize the control of the assisted driving mode, so as to provide the user with information reference for exiting intelligent driving, thereby ensuring the safety of the driver.

[0089] In one embodiment, when the present invention is applied in a non-cockpit integrated solution, since the cockpit control module and the intelligent assisted driving control module are integrated on different chips, once a problem occurs in either the cockpit control module or the intelligent assisted driving control module, an alarm can be issued through the other intact module to notify the driver to take over the vehicle.

[0090] In one embodiment, for example, when a problem occurs with the cockpit control module, an alarm message can be issued through the intelligent assisted driving control module to prompt the driver to take over the vehicle; the intelligent assisted driving control module can be used to determine whether the driver has successfully taken over the vehicle; when the driver has successfully taken over the vehicle, the intelligent assisted driving control module is controlled to exit the intelligent assisted driving mode and restart the cockpit control module.

[0091] In one embodiment, for example, when a problem occurs in the cockpit control module or the intelligent assisted driving control module, an alarm message can be issued by the cockpit control module to prompt the driver to take over the vehicle; the cockpit control module can determine whether the driver has successfully taken over the vehicle; when the driver successfully takes over the vehicle, the intelligent assisted driving control module is controlled to exit the intelligent assisted driving mode, and the driver can manually restart the intelligent assisted driving control module.

[0092] Based on the same inventive concept, the present invention also provides a control system for a vehicle intelligent assisted driving mode, comprising:

[0093] An acquisition unit 11 is used to acquire the working status of the cockpit control module;

[0094] A judging unit 12 is used to judge whether there is an abnormality in the cockpit control module;

[0095] The control unit 13 sends an alarm message through the intelligent assisted driving control module and / or the body control module and / or the alarm control module when an abnormality occurs in the cockpit control module to prompt the driver to take over the vehicle; and restarts the cockpit control module according to preset rules.
