All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
As known from the background technology, when the current vehicle controller monitors unexpected large torque or the torque change slope is too large, the torque path is directly cut off, so that the vehicle enters an unpowered safety state, and the personal safety is ensured; frequent power interruptions can severely impact driving experience, resulting in a poor user experience.
Therefore, the embodiment of the invention provides a vehicle safety monitoring method, a device, electronic equipment and a vehicle, which are used for receiving vehicle running state information and a first output torque request, and stopping responding to the first output torque request if the first output torque request is monitored to be responded and the first output torque request is judged to be failed according to the vehicle running state information so as to improve the safety of the vehicle. Then calculating a second output torque according to the vehicle running state information, and judging whether the second output torque is in a pre-calculated torque range or not; indicating that the second output torque is safely available when the second output torque is within the pre-calculated torque range, and outputting the second output torque; when the second output torque is out of the pre-calculated torque range, the second output torque is indicated to be unavailable, and at the moment, the power zero clearing operation is performed, so that the running safety of the vehicle can be effectively ensured, different operations are adopted for different fault states, the personal safety of passengers is ensured, and meanwhile, the experience of the passengers is improved.
It should be noted that, the method for monitoring vehicle safety provided by the embodiment of the invention is applied to a whole vehicle controller (Vehicle Control Unit, VCU), and the whole vehicle controller is responsible for accelerator pedal position acquisition, brake pedal position acquisition, driving torque calculation, driving mode judgment, torque coordination among functions, torque change rate adjustment and the like in a whole vehicle torque path.
Referring to fig. 1, a flowchart of a method for monitoring vehicle safety according to an embodiment of the present invention is shown, where the method includes:
step S101: when the vehicle running state information and the first output torque request are received, monitoring the response condition of the first output torque request, and judging whether the first output torque request fails or not according to the vehicle running state information; if the first output torque request fails, step S102 is performed.
It will be appreciated that if the monitoring layer monitors that the functional layer has responded to the first output torque request and the monitoring layer determines that the first output torque request has not failed based on the vehicle operating state information, the monitoring layer outputs a first output torque in the first output torque request.
The first output torque request is a torque request sent from an external controller (e.g., an intelligent driving controller) to the vehicle controller, where the first output torque request includes a first output torque, for example: automatic park assist system (AutoParkingAssist, APA) torque, adaptive cruise control system (Adaptive Cruise Control, ACC) torque, high Way Pilot (HWP) torque, and the like.
In the specific implementation process of step S101, the monitoring layer and the functional layer of the whole vehicle controller both receive the vehicle running state information, the monitoring layer monitors whether the functional layer responds to the first output torque request, and the monitoring layer judges whether the first output torque request fails according to the vehicle running state information.
Specifically, after the functional layer of the whole vehicle controller receives the first output torque request of the vehicle, the first output torque request is judged, and torque judgment information is obtained.
It is understood that the monitoring layer obtains the output torque judgment information sent by the functional layer, and if the output torque judgment information includes response information and the response information indicates that the first output torque request is responded, it is determined that the first output torque request is responded by the functional layer.
It should be noted that, as shown in fig. 2, the monitoring layer determines whether the first output torque request fails according to the vehicle running state information, and includes the following steps:
step S201: the monitoring layer obtains an execution requirement corresponding to the first output torque request.
In the specific implementation process of step S201, the monitoring layer obtains an execution requirement corresponding to the first output torque request from the database, for example, when the first output torque request is a constant speed cruise torque request, the corresponding execution requirement is that the current vehicle speed is between 30km/S and 150 km/S; for another example, when the first output torque request is an auto park torque request, its corresponding execution request is a torque value change rate limit value a.
Step S202: judging whether the running state information of the vehicle and the first output torque in the first output torque request meet the execution requirement or not; if the vehicle running state information and the first output torque meet the execution requirement, executing step S203; if the vehicle running state information does not meet the execution requirement, and/or the first output torque does not meet the execution requirement, step S204 is executed.
The vehicle running state information includes, but is not limited to, an accelerator pedal position, a brake pedal position, a vehicle speed, and the like.
In the process of specifically implementing step S202, the monitoring layer determines whether the vehicle running state information meets the execution requirement, and determines whether the first output torque in the first output torque request meets the execution requirement. The method comprises the steps of monitoring whether a functional layer responds to a torque request of an external controller unexpectedly and monitoring the correctness of the torque response, and identifying the conditions of unexpected large torque or overlarge torque change slope.
For example: judging whether the vehicle speed in the vehicle running state information is between 30km/s and 150km/s when the first output torque request is a constant-speed cruising torque request; if the vehicle speed in the vehicle running state information is not between 30km/s and 150km/s, determining that the vehicle running state information does not meet the execution requirement, for example, if the vehicle speed exceeds 150km/s, an unexpected large torque condition occurs, namely, the torque requirement in the running mode is exceeded; when the first output torque request is an automatic parking torque request, judging whether the change rate of the first output torque in the first output torque request is smaller than a limit value A or not; if the change rate of the first output torque in the first output torque request is smaller than the limit value A, determining that the first output torque meets the execution requirement; if the torque change gradient is larger than a, the torque change gradient may be excessively large.
Step S203: and if the vehicle running state information and the first output torque meet the execution requirements, determining that the first output torque request has no fault.
That is, the first output torque request is not failed and may be normally responded to.
Step S204: if the vehicle running state information does not meet the execution requirement and/or the first output torque does not meet the execution requirement, determining that the first output torque request fails.
That is, the first output torque request fails, and a safety issue will occur if continued to respond to the first output torque request.
Step S102: if the first output torque request is responded to and the first output torque request fails, the responding to the first output torque request is stopped.
In the specific implementation process of step S102, if the functional layer has responded to the first output torque request and the monitoring layer determines that the first output torque fails according to the vehicle running state information, the monitoring layer controls the functional layer to stop responding to the first output torque request, and specifically, the monitoring layer controls the torque coordination failure flag bit to be in an activated state, so that the functional layer stops responding to the first output torque request.
Step S103: calculating a second output torque according to the vehicle running state information, and judging whether the second output torque is in a pre-calculated torque range or not; when the second output torque is within the pre-calculated torque range, step S104 is performed; when the second output torque is out of the pre-calculated torque range, step S105 is performed.
In the specific implementation process of step S103, the functional layer calculates a second output torque according to the vehicle running state information, and sends the second output torque to the monitoring layer, so that the monitoring layer determines whether the second output torque is within a pre-calculated torque range.
The vehicle running state information includes, for example: accelerator pedal position, brake pedal position, vehicle speed, etc.
It will be appreciated that the process of calculating the second output torque from the vehicle operating state information is as follows:
The function layer preprocesses the vehicle running state information (such as removing abnormal values, filling missing values, carrying out data normalization and the like) to obtain preprocessed vehicle running state information; extracting characteristic parameters from the preprocessed running state information of the vehicle; and inputting the characteristic parameters into a pre-trained calculation model for calculation to obtain a second output torque.
For example: and if the first output torque is the torque of the automatic parking auxiliary system, extracting characteristic parameters (such as speed, steering wheel angle and the like) from the preprocessed running state information of the vehicle according to the calculation principle of the torque of the automatic parking auxiliary system, and inputting the characteristic parameters into a pre-trained calculation model for calculation to obtain the second output torque.
It should be noted that, the process of obtaining the calculation model through pre-selection training may be: according to the characteristics of the data and the prediction requirements, a calculation model is established, a historical data set is used for training the model, and other test data sets are used for verifying and evaluating the performance of the model, for example, cross verification, mean Square Error (MSE), mean Absolute Percentage Error (MAPE) and other indexes are used for evaluating the accuracy and generalization capability of the calculation model.
It will be appreciated that the process of pre-calculating the torque range includes: the monitoring layer acquires basic data of an automobile engine and a transmission system; and calculating according to the running state information of the vehicle and basic data of the automobile engine and the transmission system to obtain a torque range.
It is understood that different types of engines (e.g., gasoline engines, diesel engines, electric engines, etc.) have different torque characteristics. From the basic data of the motor vehicle engine and the drive train, the setpoint torque and the maximum torque value thereof can be determined. Wherein, rated torque refers to the torque value of the engine at the rated power point; the maximum torque is the maximum torque that the engine can output at a specific rotational speed. From this data, the torque range of the engine can be determined.
Further, in order to improve the reliability of the torque range, the torque range is obtained by calculating based on basic data of the automobile engine and the transmission system and combining with the running state information of the vehicle according to torque output curves of the automobile engine at different rotating speeds.
Step S104: and outputting the second output torque if the second output torque is within the pre-calculated torque range.
In the specific implementation process of step S104, if the second output torque is within the pre-calculated torque range, it is determined that the second output torque is available, and then the second output torque is output, specifically, the monitoring layer sends the second output torque to the safety arbitration module of the whole vehicle controller so as to output the second output torque through the safety arbitration module.
Step S105: and if the second output torque is out of the pre-calculated torque range, executing a power zero clearing operation.
In the specific implementation step S105, when the second output torque is out of the pre-calculated torque range, it is determined that the second output torque is unavailable, the monitoring layer controls the safety arbitration module to execute the power clearing operation, specifically, the monitoring layer controls the filtering fault flag bit to be in an activated state, and the safety arbitration module executes the power clearing operation based on the filtering fault flag bit in the activated state.
The power clearing operation is specifically to cut off a torque path, that is, cut off a power transmission path output by an engine, so that the vehicle is completely in a unpowered state. Performing the power clearing operation may ensure that the vehicle is no longer affected by the power output by the engine, thereby reducing further accident risk.
In the embodiment of the invention, the running state information of the vehicle and the first output torque request are received, if the first output torque request is monitored to be responded, and the first output torque request is judged to have faults according to the running state information of the vehicle, the torque coordination fault zone bit is controlled to be in an activated state, and the response to the first output torque request is stopped, so that the safety of the vehicle is improved. Then calculating a second output torque according to the vehicle running state information, and judging whether the second output torque is in a pre-calculated torque range or not; indicating that the second output torque is safely available when the second output torque is within the pre-calculated torque range, and outputting the second output torque; when the second output torque is out of the pre-calculated torque range, the second output torque is indicated to be unavailable, at the moment, the filtering fault zone bit is controlled to be in an activated state, the running safety of the vehicle can be effectively guaranteed by executing the power zero clearing operation, different operations are adopted for different fault states, the personal safety of passengers is guaranteed, and meanwhile the experience of the passengers is improved.
In order to better explain the content in fig. 1 of the above embodiment of the present invention, referring to fig. 3, a schematic diagram of a vehicle safety monitoring method according to an embodiment of the present invention is shown.
As shown in fig. 3, the vehicle control unit includes: an input interface module 101, a VCU functional layer torque path coordination module 102, an external controller torque request monitoring module 103, a VCU functional layer torque path filtering module 104, a VCU internal calculation torque monitoring module 105, and a safety arbitration module 106.
The function layer comprises a VCU function layer torque path coordination module 102 and a VCU function layer torque path filtering module 104; the monitoring layer includes an input interface module 101, an external controller torque request monitoring module 103, and a VCU internal calculation torque monitoring module 105.
The whole vehicle controller receives CAN signals sent by the CAN bus through the functional layer and the monitoring layer, and specifically, the input interface module 101 and the VCU functional layer torque path coordination module 102 respectively receive the CAN signals sent by the CAN bus.
The VCU functional layer torque path coordination module 102 determines the received CAN signal, and if the VCU functional layer torque path coordination module 102 sends a first output torque request in the CAN signal to the external controller torque request monitoring module 103 and the VCU functional layer torque path filtering module 104, instructs the VCU functional layer torque path coordination module 102 to respond to the first output torque request.
The external controller torque request monitoring module 103 determines whether the first output torque request fails based on the vehicle running state information in the CAN signal sent by the input interface module 101, and if the first output torque request fails, the external controller torque request monitoring module 103 controls the torque coordination failure flag bit to be in an active state, so that the VCU function layer torque path coordination module 102, the VCU function layer torque path filtering module 104, and the VCU internal calculation torque monitoring module 105 stop responding to the first output torque request. If the first output torque request does not fail, the first output torque request is output through the VCU internal calculation torque monitoring module 105 and the safety arbitration module 106.
It can be appreciated that when the torque coordination fault flag is in an active state, the VCU functional layer torque path filtering module 104 calculates a second output torque based on the vehicle operating state information; the second output torque is sent as a torque request to the VCU internal computing torque monitoring module 105.
Specifically, the VCU internal calculation torque monitoring module 105 receives the CAN signal forwarded by the external controller torque request monitoring module 103, and obtains basic data of an automobile engine and a transmission system; and calculating according to the vehicle running state information in the CAN signal and basic data of the automobile engine and the transmission system to obtain a torque range. And judging whether the second output torque is in the torque range, and outputting the second output torque through the safety arbitration module 106 if the second output torque is in the torque range.
It should be noted that, if the second output torque is outside the torque range, the VCU internal calculation torque monitoring module 105 controls the filter fault flag bit to be in an activated state, so that the safety arbitration module 106 clears the second output torque, and performs a power clearing operation.
In the embodiment of the invention, when the first output torque is unavailable, the response to the first output torque request is immediately stopped, namely, the torque coordination fault zone bit is controlled to be in an activated state, so that the functional layer stops responding to the first output torque request, and the safety of the vehicle is improved; when the second output torque is available, the second output torque is output, and when the second output torque is not available, the power zero clearing operation is adopted, and different operations are adopted for different fault states, so that the experience of passengers is improved.
