Combination.
As it is shown in figure 1, the vehicle dynamic speed limiting system of a kind of embodiment, including:
Speed limit acquisition module 110, for receiving the restriction limiting vehicle maximum travel speed that monitor supervision platform sends
Speed.
Speed limit acquisition module 110 can be realized by signal receiver.Limit speed and passed through nothing by signal receiver
Gauze network receives.Different time, different location restriction speed can be different.
Speed data collection module 130, for obtaining the real time running speed of vehicle.
The travel speed of speed data collection module 130 Real-time Collection vehicle, can be realized by vehicle sensors.
Comparator 150, connects described speed limit acquisition module 110 and described speed data collection module 130, and being used for will
Described restriction speed compares with described travel speed, whether obtains described restriction speed less than described traveling
The comparative result of speed.
When limiting speed not less than described travel speed, illustrate that travel speed meets speed limit requirement, it is not necessary to
Carry out speed restriction further.
When limit speed less than described travel speed time, illustrate that travel speed does not meets speed limit requirement, need into
One stepping line speed limits.
ECU control module 170, is connected with described comparator 150, is used for when described comparative result is described
When limiting speed less than described travel speed, the travel speed of vehicle is declined preset value.
When described comparative result is described restriction speed less than described travel speed, illustrate that travel speed is not inconsistent
Close speed limit requirement, by the way of the travel speed of vehicle is declined preset value, carry out speed restriction.
In the present embodiment, preset value can be a fixed speed.
Timer 190, connects described comparator 150, for every Preset Time, triggers described comparator 150
Work.
Preset Time is fixing duration, so can ensure that travel speed declines the traveling speed of preset value rear vehicle
Degree meets speed limit requirement, or can ensure that the travel speed of subsequent time vehicle meets speed limit requirement.
Above-mentioned vehicle dynamic speed limiting system, timer 190 is every Preset Time, and trigger comparator 150 will limit
The travel speed that the restriction speed that speed acquisition module 110 receives and speed data collection module 130 obtain compares,
Obtain whether described restriction speed is less than the comparative result of described travel speed.When described comparative result is described
When limiting speed less than described travel speed, the travel speed of vehicle is declined by ECU control module 170 to be preset
Value.So, it is ensured that the travel speed of vehicle can dynamically meet what speed limit acquisition module 110 got
The restriction requirement of vehicle maximum travel speed.
Wherein in an embodiment, monitor supervision platform is mobile phone or computer.
Wherein in an embodiment, described ECU control module 170 controls, by sending, the control that gear declines
System instruction, with control engine speed decline preset rotation speed realize vehicle travel speed decline preset value.
Specifically, described speed data collection module 130 realizes also by ECU control module 170, is specially logical
Cross ECU control module 170 to gather engine speed and determine the real time running speed of vehicle.
Wherein in an embodiment, described electronic control unit obtains real time running speed by CAN,
And issue described control shelves by CAN (Controller Area Network, controller local area network) bus
The control instruction that position declines.
Wherein in an embodiment, described speed data collection module 130 is gathered by ECU control module 170
Engine speed determines the real time running speed of vehicle.
As in figure 2 it is shown, wherein in an embodiment, described speed limit acquisition module 110 includes being in communication with each other
The signal receiver 111 connected and decoder 113.Described signal receiver 111, is used for passing through wireless network
Receiving the speed limit instruction comprising described restriction speed, described decoder 113, for carrying out the instruction of described speed limit
Decoding, obtains limiting speed.
Specifically, the described speed limit instruction that described signal receiver 111 receives can be SMS form
The instruction of restricted speed, it is also possible to the finger of the restricted speed of data message form for being sent by wireless network
Order.
A kind of vehicle, including: car body and above-mentioned vehicle dynamic speed limiting system.
Above-mentioned vehicle, owing to the timer 190 of vehicle dynamic speed limiting system compares every Preset Time, triggering
The traveling speed that the restriction speed that speed limit acquisition module 110 is received by device 150 and speed data collection module 130 obtain
Degree compares, and obtains whether described restriction speed is less than the comparative result of described travel speed.When described ratio
When relatively result is described restriction speed less than described travel speed, ECU control module 170 is by the traveling of vehicle
Speed declines preset value.So, it is ensured that the travel speed of vehicle can dynamically meet speed limit acquisition module
The restriction requirement of the vehicle maximum travel speed that 110 get.
Above example only have expressed several embodiments of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for this
For the those of ordinary skill in field, without departing from the concept of the premise utility, it is also possible to make many
Individual deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, this utility model patent
