[0002] With the improvement of people's living standards, vehicles have become a common means of transportation for people to go out. During the process of driving a vehicle, when people encounter traffic jams while driving, they often choose to change lanes according to the traffic conditions of the adjacent roads on the left and right. At this time, the driver usually turns the steering wheel to the right or left to wait for an opportunity to change lanes. However, when the road ahead suddenly becomes unobstructed, the driver sometimes habitually steps on the accelerator hard to catch up with the vehicle in front, but forgets that the traveling direction of the vehicle at this time is not straight ahead. At this time, if there are adjacent vehicles, it is very easy to collide with the adjacent vehicle, thus resulting in a traffic accident. Summary of the Invention

[0034] To enable those skilled in the art to better understand the technical solutions of the present invention, the assisted driving method, device, vehicle-mounted system and storage medium provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Example embodiments will be described more fully hereinafter with reference to the accompanying drawings, but the example embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0036] The terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the invention. As used herein, the singular forms "a" and "the" are also intended to include the plural forms, unless the context clearly indicates otherwise. It will also be understood that when the present specification uses the terms "comprises" and / or "consists of", it specifies the presence of the stated features, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or their groups.

[0037] It will be understood that although terms such as first, second, etc. may be used herein to describe various elements / instructions / requests, these elements / instructions / requests should not be limited by these terms. These terms are only used to distinguish one element / instruction / request from another element / instruction / request.

[0038] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in common dictionaries should be interpreted as having a meaning consistent with their meaning in the relevant art and the context of the present invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0039] In the prior art, vehicles generally use methods such as front vehicle radar and lane change assist to remind drivers of problems encountered during vehicle driving. However, if the driver suddenly steps on the accelerator due to impatience or other reasons, especially for vehicles with relatively fast acceleration, there will be a situation where the driver finds that there are vehicles on the left and right but there is not enough time to step on the brakes, resulting in collisions with the vehicles on the left and right. The assisted driving method provided by the present invention is used to solve this technical problem, and this method can be implemented based on an assisted driving device.

[0040] Figure 1 It is a flowchart of an assisted driving method provided by the present invention, as Figure 1 shown, this method includes:

[0041] Step S101, in response to the driving speed of the vehicle being less than or equal to a preset speed and the steering wheel direction being biased within a first preset time period, monitor the instantaneous fuel consumption value of the vehicle.

[0042] In the present invention, when the driving speed of the vehicle is less than or equal to the preset speed and the steering wheel direction is biased within the first preset time period, it indicates that the vehicle is about to deviate from the forward direction of travel. For example, during a traffic jam, lane changing, etc. At this time, monitoring the instantaneous fuel consumption value of the vehicle can timely detect improper operations of the vehicle driver, such as sudden acceleration, etc. Among them, the first preset time period and the preset speed can be set by those skilled in the art according to the actual application scenario. For example, the first preset time is 3 seconds, and the preset speed is 0 or 5 KM / H, etc.; the steering wheel direction being biased means that the direction of the steering wheel deviates from the forward direction (the direction of the vehicle head) of the vehicle by a certain angle to the left or right.

[0043] Step S102, determine whether the monitored instantaneous fuel consumption value reaches a first preset reference value within a second preset time period.

[0044] The second preset time period is a time period set by those skilled in the art according to the actual application scenario. For example, the second preset time period is 0.5 s, and the first preset reference value is a standard reference value set according to the maximum fuel consumption value of the vehicle. For example, the first preset reference value can be 50% of the maximum fuel consumption value of the vehicle.

[0045] Specifically, in step S102, the sample instantaneous fuel consumption value of the vehicle can be collected at regular time intervals within the second preset time period, and the sample instantaneous fuel consumption value is compared with the first preset reference value. If the sample instantaneous fuel consumption value reaches the first preset reference value, it indicates that the driver wants to perform a rapid acceleration at this time. At this time, the following step S103 is executed, that is, a reminder message is sent to remind the driver that the steering wheel direction of the vehicle is not forward at this time, and the accident risk will increase if a rapid acceleration is performed; if the sample instantaneous fuel consumption value is less than the first preset reference value, it indicates that the acceleration of the vehicle will not be large, and no reminder is required, and the process returns to step S101.

[0046] Step S103: Send a reminder message.

[0047] The assisted driving method provided by the present invention monitors the change of the instantaneous fuel consumption value of the vehicle to send a reminder message to the driver when the vehicle speed is less than or equal to the preset speed and the steering wheel direction is biased within a certain time period. Therefore, when the driver forgets the current steering wheel bias of the vehicle and suddenly accelerates, a reminder message can be sent to the driver in time to reduce the incidence of traffic accidents.

[0048] Figure 2 is a flowchart of another assisted driving method provided by the present invention. As Figure 2 shown, on the basis of the embodiment shown in Figure 1 before step S101, the method further includes:

[0049] Step S100a: Monitor the state data of the vehicle.

[0050] Step S100b: Monitor whether the driving speed is continuously less than or equal to the preset speed within the first preset time period, and monitor whether the steering wheel direction is continuously biased within the first preset time period.

[0051] In this embodiment, when determining whether it is necessary to monitor the instantaneous fuel consumption value of the vehicle, it is determined by monitoring the status data of the vehicle. Specifically, the status data may include: driving speed and steering wheel direction. When it is monitored that the driving speed is continuously less than or equal to the preset speed within the first preset time period, and the steering wheel direction is continuously biased within the first preset time period, it is determined that it is necessary to further monitor the fuel consumption value of the vehicle. In the present invention, the status data can be obtained from the electronic control unit (Electronic Control Unit, abbreviated as ECU) of the vehicle through the controller area network (CAN network), in-vehicle Ethernet or other vehicle internal communication networks, or by simultaneously running different in-vehicle network protocol stacks or by communicating with the MCU (Microcontroller Unit, abbreviated as MCU) to obtain vehicle data. The acquisition interval during the monitoring data process is the minimum period of the signal value specified in the in-vehicle network protocol stack.

[0052] Figure 3 It is a flowchart of another assisted driving method provided by the present invention. As Figure 3 shown, on the basis of the method shown in Figure 1 this embodiment, after step S102, it further includes:

[0053] Step S104, determine whether the monitored instantaneous fuel consumption value reaches the second preset reference value within the second preset time period.

[0054] If it is determined that the monitored instantaneous fuel consumption value reaches the second preset reference value within the second preset time period, then execute steps S105 and S106.

[0055] Step S105, send an alarm message.

[0056] Step S106, send a braking instruction.

[0057] In this embodiment, the second preset reference value is greater than the first preset reference value. The meanings of the second preset reference value and the first preset reference value are the same, and both are a standard reference value set according to the maximum fuel consumption value of the vehicle. In this embodiment, the second preset reference value can be 70% of the maximum fuel consumption value of the vehicle.

[0058] Specifically, in step S104, similar to step S102, when it is determined that the instantaneous fuel consumption value reaches the first preset reference value within the second preset time period, further, the instantaneous fuel consumption value is compared with the second preset reference value. If the instantaneous fuel consumption value reaches the second preset reference value, it indicates that the driver's acceleration is too large. At this time, steps S105 and S106 are executed. On the one hand, a warning message is sent to the driver to warn the driver that there is a greater risk in the current driving behavior. On the other hand, a braking instruction is sent to the vehicle ECU to assist in emergency braking of the vehicle.

[0059] It should be noted that although both the warning message in this embodiment and the reminder message in the above embodiment play a prompting role for the vehicle driver, their contents are different. Due to the different scenarios corresponding to the warning message and the reminder message, the content of the warning message can attract the driver's attention more. For example, the warning message has a higher sound frequency than the reminder message to attract the driver's attention.

[0060] Figure 4 It is a flowchart of another assisted driving method provided by the present invention. As Figure 4 shown, on the basis of the method shown in Figure 3 this embodiment, after steps S105 and S106, it further includes:

[0061] Step S107: Monitor whether the direction of the steering wheel is adjusted from a deviation to a positive direction within the third preset time period.

[0062] If it is monitored that the direction of the steering wheel is adjusted from a deviation to a positive direction within the third preset time period, then the following step S108 is executed; if it is monitored that the direction of the steering wheel is not adjusted from a deviation to a positive direction within the third preset time period, then step S109 is executed.

[0063] Step S108: Increase the signal value of the braking instruction.

[0064] Step S109: Cancel the braking instruction.

[0065] In this embodiment, after the warning message and the braking instruction are issued, it is further monitored whether the vehicle steering wheel is adjusted from a deviation to a positive direction within the third preset time period. Among them, the third preset time period is a time period set by those skilled in the art according to the actual application scenario. Preferably, the third preset time period is 0.5 s. Specifically, when it is monitored that the vehicle steering wheel is adjusted from a deviation to a positive direction within the third preset time period, it indicates that the driver has noticed the problem that the steering wheel direction is not positive at this time. At this time, the braking signal value is increased to assist the driver in decelerating or braking the vehicle; when it is monitored that the vehicle steering wheel does not have a tendency to return to the positive within the third preset time period, it indicates that the driver wants to continue to move forward with a deviation. At this time, the braking signal should be cancelled to avoid hindering the driver's normal driving.

[0066] Figure 5 The flowchart of yet another assisted driving method provided by the present invention is as follows. As Figure 5 shown, based on the method shown in Figure 1 , before step S101, it further includes:

[0067] Step S101': Detect whether the signal value of the accelerator pedal increases.

[0068] In this embodiment, before monitoring the instantaneous fuel consumption value of the vehicle, the signal value of the vehicle's accelerator pedal is first monitored. When the signal value of the accelerator pedal increases, it indicates that the driver intends to start accelerating. At this time, the instantaneous fuel consumption value of the vehicle can be further monitored to take corresponding assisted driving measures according to the instantaneous fuel consumption value. By first detecting the signal value of the accelerator pedal to determine whether the instantaneous fuel consumption value needs to be analyzed, this embodiment can speed up the assisted driving processing flow, thereby avoiding the reduction in the speed of the processing flow caused by directly analyzing the instantaneous fuel consumption value.

[0069] In this embodiment, the acquisition method of the pedal signal is the same as the acquisition methods of the above-mentioned driving speed and steering wheel direction, and both can be obtained from the vehicle's ECU through a Controller Area Network (CAN network), in-vehicle Ethernet, or other vehicle internal communication networks.

[0070] Figure 6 The structural schematic diagram of an assisted driving device provided by the present invention is as follows. As Figure 6 shown, the device includes: a monitoring module 11 and a reminder module 12. Among them, the monitoring module 11 is used to monitor the instantaneous fuel consumption value of the vehicle in response to the driving speed of the vehicle being less than or equal to a preset speed and the steering wheel direction being deflected within a first preset time period; the reminder module 12 is used to send a reminder message when the monitoring module 11 monitors that the instantaneous fuel consumption value reaches a first preset reference value within a second preset time period.

[0071] The assisted driving device provided in this embodiment is used to implement the above-mentioned Figure 1 shown assisted driving method. For the detailed description of the specific functional modules of this assisted driving device, please refer to the description of the corresponding method steps in the Figure 1 shown method, which will not be elaborated here.

[0072] For the assisted driving device provided by the present invention, when the driving speed of the vehicle is less than or equal to a preset speed and the steering wheel direction is deflected within a certain time period, it sends a reminder message to the driver by monitoring the change of the instantaneous fuel consumption value of the vehicle. Thus, in the case where the driver forgets the current deflection of the steering wheel and suddenly accelerates, a reminder message can be sent to the driver in a timely manner to reduce the incidence of traffic accidents.
