It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. [0059] The execution of the vehicle speed control method mentioned in the embodiments of the present invention relies on a computer program that can run on a computer system of the Von Oyman system. The computer program runs based on the vehicle speed control device. The computer system can be a device such as an onboard unit.

[0060] It is to be understood that the terminology used in the embodiments of the present invention is for the purpose of describing particular embodiments, and is not intended to limit the invention. The singular forms "a", "the" and "the" It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0061] Each of the following will be described in detail.

1 is a schematic flowchart of a method for controlling a vehicle speed according to an embodiment of the present invention, and the method may include:

[0063] Step S101: Acquire a current integrated environment parameter collected by the sensor.

[0064] Specifically, the sensor includes at least one of a temperature sensor, a humidity sensor, a light sensor, a smoke detector, an air quality detector, and a visibility tester, respectively, for collecting temperature, humidity, and light intensity outside the vehicle. Parameters such as PM2.5 index, visibility, and air quality are excellent, and the current comprehensive environmental parameters are determined by these parameters.

[0065] For example, if the collected parameters are: temperature is 350C, humidity is 60%, visibility (visibility) is 2km, and the current environment is determined by processing analysis to be summer daytime, humidity is suitable, and visibility is high, The current comprehensive environmental parameters are high visibility during the day.

[0066] For another example, if the collected parameters are: 300C, humidity 90%, visibility 10

0~200m, through processing analysis to determine the current environment is summer evening, air dry and low visibility

, Get the current comprehensive environmental parameters for rainy days with low visibility at night.

[0067] Optionally, the collection mode may be real; or may be periodic, such as once every 20 minutes, which is not specifically limited herein.

[0068] Step S102: Generate a vehicle speed control instruction according to the current integrated environment parameter.

[0069] Specifically, the instruction is a command instructing the computer to perform some operation. It consists of a string of binary digits, usually consisting of two parts: the opcode and the address code. Where the opcode indicates the type or nature of the operation to be completed by the instruction, such as fetching, adding or outputting data, and the address code indicating the inside of the operating object The location of the storage unit. The lowest level instruction is a string of 0s and 1s, indicating that an entity job operation is to be run. Depending on the type of instruction, a specific area of storage is called a "register" that contains the data or data storage locations that can be used to call up instructions.

[0070] In this embodiment, the control instruction includes an acceleration instruction and a deceleration instruction. For example, when driving on a sunny day with high visibility, an acceleration command can be generated, and a deceleration command can be generated correspondingly when driving with a low visibility or an uneven road section.

[0071] Step S103, adjusting the vehicle speed according to the control command, and driving at the adjusted vehicle speed.

[0072] Specifically, if an acceleration command is generated, the current vehicle speed is increased correspondingly, and if a deceleration command is generated, the current vehicle speed is adjusted to be smaller, and then the vehicle speed is adjusted at the adjusted vehicle speed.

[0073] For example, if the current integrated environmental parameter is driving at a high speed with a visibility of 2 km, and the current traveling speed is 70 km/h, if the currently generated control command is an acceleration command, the current driving speed is adjusted correspondingly, for example, adjusted to 100 km/h, then drive at 100 km/h.

[0074] For another example, if the current integrated environmental parameter is driving on a rainy day with a visibility of lkm, and the current traveling speed is 80 km/h, if the currently generated control command is a deceleration command, the current driving speed is correspondingly adjusted to 60. Km/h, then drive at 60 km/h.

[0075] Optionally, if the adjusted driving speed is less than a minimum speed limit of the current driving section or greater than a maximum speed limit of the current driving section, the current driving speed is adjusted to a standard speed limit and then traveled.

[0076] In the embodiment of the present invention, when the vehicle speed control device acquires the current comprehensive environmental parameters collected by the sensor吋

The vehicle speed control command is generated according to the collected parameters, and the vehicle speed is adjusted correspondingly, and the vehicle is driven at the adjusted vehicle speed. By detecting the environment, the driving speed is controlled correspondingly, thereby improving the safety of driving.

2 is a schematic flow chart of a vehicle speed control method according to another embodiment of the present invention, and the method may include:

[0079] Specifically, the sensor includes at least one of a temperature sensor, a humidity sensor, a light sensor, a smoke detector, an air quality detector, and a visibility tester, respectively, for collecting temperature, humidity, and light intensity outside the vehicle. Parameters such as PM2.5 index, visibility, and air quality are excellent, and the current comprehensive environmental parameters are determined by these parameters.

[0080] For example, if the collected parameters are: temperature is 350C, humidity is 60%, visibility (visible Degree) is 2km. Through processing analysis, it is determined that the current environment is summer daytime, humidity is suitable and visibility is high, and the current comprehensive environmental parameters are obtained for daytime visibility.

[0083] Step S202: Generate a vehicle speed control instruction according to the current integrated environment parameter.

[0084] Specifically, the instruction is a command instructing the computer to perform some operation.

[0100] Specifically, the maximum vehicle speed of the current driving section is obtained, and the speed of the accelerated vehicle is compared with the obtained maximum vehicle speed, and it is determined whether the speed of the accelerated vehicle is higher than the maximum speed, and if so, the speed of the accelerated vehicle is reduced. You can drive at the highest speed of the section. The maximum vehicle speed for obtaining the road segment may be monitored and acquired by the vehicle monitoring device, or may be sent to the vehicle-mounted unit by the vehicle networking server, which is not limited.
