For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
First embodiment
Referring to fig. 1, a flow chart of a vehicle speed control method of a two-wheeled vehicle according to the present embodiment is provided, and the method includes the following steps:
s101: acquiring running data of a target two-wheel vehicle; the driving data comprise the load capacity, the wind resistance coefficient and the current speed of the target two-wheel vehicle.
In this embodiment, any two-wheeled vehicle that needs to be subjected to vehicle speed control is defined as a target two-wheeled vehicle, so that whether the target two-wheeled vehicle needs to be controlled to be subjected to speed reduction at the current moment can be accurately determined, and running safety of the target two-wheeled vehicle is ensured. First, the vehicle-mounted controller and various vehicle-mounted sensors of the target two-wheeled vehicle need to acquire the running data of the target two-wheeled vehicle at the current moment, so as to execute the following step S102.
The driving data of the target two-wheel vehicle at the current moment can include, but is not limited to, the carrying capacity, the wind resistance coefficient and the current speed of the target two-wheel vehicle. For example, the load capacity of the target two-wheeled vehicle can be measured in real time by a vehicle-mounted load measuring device (such as a vehicle-mounted load capacity sensor) of the target two-wheeled vehicle; the wind resistance coefficient can be measured in real time through a vehicle-mounted wind resistance measuring device (such as a vehicle-mounted wind resistance coefficient sensor) of the target two-wheeled vehicle; the current speed of the target two-wheeled vehicle can be measured in real time by a vehicle-mounted speed measuring device (such as a vehicle-mounted speed sensor) of the target two-wheeled vehicle, and the like.
It should be noted that, the specific method for acquiring the running data of the target two-wheeled vehicle at the current moment is not limited in this application, and may be selected according to the actual situation, and the above-mentioned various data acquisition methods are only preferred exemplary methods set forth in this application.
In addition, it should be noted that, the running data such as the load capacity, the wind resistance coefficient and the current speed of the target two-wheeled vehicle can be uploaded to the service end through the communication device controlled by the vehicle-mounted controller, and the following steps S102-S103 are executed to perform analysis processing, so as to realize intelligent speed control of the target two-wheeled vehicle.
The uploading interval of the driving data of the target two-wheeled vehicle can be set according to practical situations, for example, the uploading interval can be set to be once every 10 seconds. In general, the travel data of the target two-wheeled vehicle is acquired after the target two-wheeled vehicle starts traveling.
S102: and calculating the reasonable speed range of the target two-wheeled vehicle by utilizing a dynamic load speed measurement algorithm according to the load capacity and the wind resistance coefficient of the target two-wheeled vehicle.
In this embodiment, after the running data such as the load capacity and the wind resistance coefficient of the target two-wheel vehicle at the current moment is obtained in step S101, in order to accurately determine whether the target two-wheel vehicle needs to be controlled to slow down at the current moment so as to ensure the running safety of the target two-wheel vehicle, the whole vehicle mass, the rated maximum vehicle speed and the minimum vehicle speed of the target two-wheel vehicle need to be obtained (which is defined as V herein min ) Therefore, the reasonable speed range of the target two-wheel vehicle can be calculated by utilizing a dynamic load speed measurement algorithm according to the load capacity, the wind resistance coefficient and the whole vehicle mass and the rated maximum speed of the target two-wheel vehicle, and the reasonable speed range of the target two-wheel vehicle can be used for executing the following step S103.
The calculation formula of the highest vehicle speed in the reasonable vehicle speed range of the target two-wheel vehicle is as follows:
V＝V max -((|M driver -M car |)/M car *V max )*C
wherein V represents the highest speed in a reasonable speed range of the target two-wheeled vehicle; v (V) max The rated maximum speed of the target two-wheel vehicle is represented; m is M driver Representing the load capacity of the target two-wheeled vehicle; m is M car Representing the whole vehicle quality of the target two-wheel vehicle; c represents the wind resistance coefficient.
On the basis, the reasonable speed range of the target two-wheel vehicle can be determined to be the minimum speed V min To the highest vehicle speed V.
Illustrating: suppose the load capacity M of the target two-wheeled vehicle driver 65kg, a windage coefficient C of 1.2 and a target whole mass M of the two-wheeled vehicle car 55kg, rated maximum vehicle speed V max 25km/h, minimum vehicle speed V min If the speed is 10km/h, the highest speed V in the reasonable speed range of the target two-wheeled vehicle can be calculated to be 19.55km/h through the formula, namely V=25- ((|65-55|) per 55×25) 1.2 approximately 19.55km/h. And further, the reasonable speed range of the target two-wheeled vehicle is 10 km/h-19.55 km/h.
S103: judging whether the current speed of the target two-wheeled vehicle is within a reasonable speed range of the target two-wheeled vehicle, and determining whether to control the target two-wheeled vehicle to reduce the speed according to a judging result so as to ensure the running safety of the target two-wheeled vehicle.
In this embodiment, after the reasonable speed range of the target two-wheel vehicle is calculated in step S102, it may be further determined whether the current speed of the target two-wheel vehicle is within the reasonable speed range of the target two-wheel vehicle, so as to obtain a determination result, and according to the determination result, it is determined whether to control the target two-wheel vehicle to slow down, so as to ensure the running safety of the target two-wheel vehicle. Specifically, when the judgment result shows that the current speed of the target two-wheel vehicle is within the reasonable speed range of the target two-wheel vehicle, the target vehicle is controlled to continue to run at the current speed. Or when the judgment result shows that the current speed of the target two-wheel vehicle is not in the reasonable speed range of the target two-wheel vehicle, controlling the target vehicle to run at a reduced speed.
An optional implementation manner is that when the judgment result is that the current speed of the target two-wheel vehicle is in a reasonable speed range of the target two-wheel vehicle and the difference between the current speed of the target two-wheel vehicle and the highest speed in the reasonable speed range is smaller than a preset threshold value, the target two-wheel vehicle is determined to be about to overspeed; and then the vehicle-mounted controller of the target two-wheel vehicle can send an overspeed command to the vehicle-mounted controller of the target two-wheel vehicle, so that the vehicle-mounted controller responds to the overspeed command to send out overspeed-ready voice prompt information through preset vehicle-mounted equipment for prompting a driver to pay attention to driving safety.
In this implementation manner, when the server determines that the current speed of the target two-wheeled vehicle is within the reasonable speed range of the target two-wheeled vehicle, and the difference between the current speed of the target two-wheeled vehicle and the highest speed in the reasonable speed range is smaller than the preset threshold, it may be determined that the target two-wheeled vehicle is about to overspeed, at this time, in order to ensure the running safety of the target two-wheeled vehicle, an overspeed-about instruction needs to be sent to an on-board controller (Electronic Control Unit, abbreviated as ECU) of the target two-wheeled vehicle, so that the on-board controller responds to the overspeed-about instruction, sends a voice prompt message about overspeed about to the driver through the preset on-board device, so as to prompt the driver to pay attention to the driving safety, for example, may be properly decelerated.
The specific value of the preset threshold value can be set according to actual conditions, and in the embodiment of the application, the preset threshold value can be set to be 1km/h instead of being set. The preset vehicle-mounted device for sending the voice prompt information can be set according to actual conditions, and the embodiment of the application can never select, for example, the vehicle-mounted intelligent helmet of the target two-wheel vehicle can send the voice prompt information about overspeed to the driver for prompting the driver to pay attention to driving safety.
Illustrating: the reasonable speed range of the target two-wheeled vehicle is calculated to be 10 km/h-19.55 km/h by the service end, the current speed of the target two-wheeled vehicle is 18.55km/h, the preset threshold value is 1km/h, and the difference between the current speed of the target two-wheeled vehicle and the highest speed of 19.55km/h in the reasonable speed range is smaller than the preset threshold value of 1km/h, so that the target two-wheeled vehicle can be judged to be about to overspeed at the moment, and at the moment, in order to ensure the driving safety of the target two-wheeled vehicle, an overspeed-about instruction needs to be sent to an on-board controller ECU of the target two-wheeled vehicle, so that the on-board controller ECU responds to the overspeed-about instruction and sends overspeed-about voice prompt information to a driver through an on-board intelligent helmet for prompting the driver to pay attention to driving safety.
In another alternative implementation manner, when the judgment result is that the current speed of the target two-wheel vehicle is not in the reasonable speed range of the target two-wheel vehicle and the difference between the current speed of the target two-wheel vehicle and the highest speed in the reasonable speed range is not smaller than a preset threshold value, the target two-wheel vehicle is determined to have overspeed, even serious overspeed; and then can send the instruction of slowing down to the vehicle-mounted controller of target two-wheeled vehicle to the vehicle-mounted controller responds to this instruction of slowing down, send out the voice prompt message that has overspeed even seriously overspeed through presetting vehicle-mounted device, be used for prompting the driver to pay attention to driving safety, and automatic control target two-wheeled vehicle is slowed down to within the reasonable speed range.
In the implementation manner, when the server side judges that the current speed of the target two-wheel vehicle is not in the reasonable speed range of the target two-wheel vehicle, and the difference between the current speed of the target two-wheel vehicle and the highest speed in the reasonable speed range is not smaller than a preset threshold value, the target two-wheel vehicle can be determined to be overspeed or even severely overspeed, at the moment, in order to ensure the running safety of the target two-wheel vehicle, a speed reducing instruction needs to be sent to an ECU (electronic control unit) of the target two-wheel vehicle, so that the vehicle controller responds to the speed reducing instruction, a voice prompt message of overspeed or severely overspeed is sent to a driver through preset vehicle-mounted equipment, and the voice prompt message is used for prompting the driver to pay attention to the driving safety, and the speed of the target two-wheel vehicle is automatically controlled to be reduced to the reasonable speed range, so that the running safety of the target two-wheel vehicle is ensured.
The specific value of the preset threshold value can be set according to actual conditions, and in the embodiment of the application, the preset threshold value can be set to be 1km/h instead of being set. The preset vehicle-mounted device for sending the voice prompt information can be set according to actual conditions, and the embodiment of the application can never select, for example, the vehicle-mounted intelligent helmet of the target two-wheel vehicle can send out the voice prompt information of overspeed or serious overspeed to a driver, so that the driver is prompted to pay attention to driving safety, and the target two-wheel vehicle is automatically controlled to be slowed down within a reasonable vehicle speed range, so that the driving safety of the target two-wheel vehicle is ensured.
Illustrating: the service end is assumed to calculate that the reasonable speed range of the target two-wheeled vehicle is 10 km/h-19.55 km/h, the current speed of the target two-wheeled vehicle is 21km/h, the preset threshold value is 1km/h, and the difference between the current speed of the target two-wheeled vehicle and the highest speed of 19.55km/h in the reasonable speed range is not smaller than the preset threshold value of 1km/h, so that the target two-wheeled vehicle can be judged to be overspeed at the moment, and at the moment, in order to ensure the driving safety of the target two-wheeled vehicle, a speed reduction instruction needs to be sent to an on-board controller ECU of the target two-wheeled vehicle, so that the on-board controller ECU responds to the speed reduction instruction, a voice prompt message of serious overspeed is sent to a driver through an on-board intelligent helmet, and the voice prompt message is used for prompting the driver to pay attention to driving safety, and the speed reduction of the target two-wheeled vehicle is automatically controlled to be within the reasonable speed range, so that the driving safety of the target two-wheeled vehicle is ensured.
Or, assuming that the current speed of the target two-wheeled vehicle is 24km/h and the preset threshold value of the severe overspeed is 4km/h, it can be determined that the difference between the current speed of the target two-wheeled vehicle and the highest speed of 19.55km/h in the reasonable speed range is not less than the preset threshold value of the severe overspeed of 4km/h, so that the target two-wheeled vehicle can be judged to be severe overspeed at the moment, in order to ensure the running safety of the target two-wheeled vehicle, a speed reduction instruction needs to be sent to an on-board controller ECU of the target two-wheeled vehicle, so that the on-board controller ECU responds to the speed reduction instruction, sends out overspeed voice prompt information to a driver through an on-board intelligent helmet for prompting the driver to pay attention to the running safety, and automatically controls the speed reduction of the target two-wheeled vehicle to be within the reasonable speed range so as to ensure the running safety of the target two-wheeled vehicle.
