Abstract
The invention discloses a kind of methods based on road speed limit target value restricted speed.The method based on road speed limit target value restricted speed is the following steps are included: step 1, the network platform, by vehicle location, obtain section speed limit value by car-mounted terminal return data；And local section speed limit value information is issued into car-mounted terminal in time, car-mounted terminal passes information to ECU after receiving section speed limit value；Step 2 after ECU obtains local section speed limit value information, participates in practical control and calculates, control diesel engine operation.The method based on road speed limit target value restricted speed is based on vehicle location, and the speed limit value dynamic of road is sent to engine, realizes the received speed limit target dynamic of ECU, vehicle can be responded according to section speed limit Intelligent target, overspeed of vehicle is avoided, the safety is improved, guarantee driving safety.
Description
Technical field
The present invention relates to engine arts, especially with regard to a kind of side based on road speed limit target value restricted speed
Method.
Background technique
In diesel engines at present application, max. speed limitation function is according to current vehicle speed (vehicle speed sensor acquisition) and setting
Curb-top speed (calibration value) and the information such as gear calculate a driving limitation torque, which will be turned
It is changed to the maximum permissible torque of engine, the torque starts to calculate when speed is close to target vehicle speed, if speed is more than target value
The limitation torque will reduce until being 0, to achieve the purpose that restricted speed.
But in high-speed working condition, different sections of highway limit value speed target value is different, but ECU only supports speed target fixed value at present
(after data are once demarcated successfully, writing with a brush dipped in Chinese ink into ECU, immutable), can not achieve dynamic limitation speed, cause respective road segment because
Hypervelocity causes traffic safety hidden danger.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
Summary of the invention
The purpose of the present invention is to provide a kind of sides based on road speed limit target value restricted speed of simple and reasonable steps
Method, should method based on road speed limit target value restricted speed can be realized the received speed limit target dynamic of ECU, vehicle can be with
It is responded according to section speed limit Intelligent target, avoids overspeed of vehicle, the safety is improved, guarantee driving safety.
To achieve the above object, the present invention provides a kind of methods based on road speed limit target value restricted speed, including
Following steps: step 1, the network platform, by vehicle location, obtain section speed limit value by car-mounted terminal return data；And it will work as
Ground section speed limit value information issues car-mounted terminal in time, and car-mounted terminal passes information to ECU after receiving section speed limit value；Step
After two, ECU obtain local section speed limit value information, participates in practical control and calculate, control diesel engine operation.
In a preferred embodiment, car-mounted terminal is GPS terminal.
In a preferred embodiment, car-mounted terminal is passed information to after receiving atmospheric humidity by CAN bus
ECU。
In a preferred embodiment, information is issued car-mounted terminal by mobile base station by the network platform.
Compared with prior art, the method according to the present invention based on road speed limit target value restricted speed has and has as follows
Beneficial effect: it should be based on vehicle location based on the method for road speed limit target value restricted speed, the speed limit value dynamic of road was sent
To engine, the received speed limit target dynamic of ECU is realized, vehicle can be responded according to section speed limit Intelligent target, avoid vehicle
Hypervelocity, the safety is improved, guarantee driving safety.
Detailed description of the invention
Fig. 1 is the signal of the method based on road speed limit target value restricted speed of first embodiment according to the present invention
Figure.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, vehicle location is based on, by the speed limit value of road when vehicle driving is in fastlink or city road
Dynamic is sent to engine, realizes the received speed limit target dynamic of ECU, and vehicle can be rung according to section speed limit Intelligent target
It answers, avoids overspeed of vehicle, guarantee driving safety.It is according to the preferred embodiment of the invention to be based on road speed limit target value restricted speed
Method specifically includes the following steps:
Step 1, the network platform, by vehicle location, obtain section speed limit value by car-mounted terminal return data.And it will be local
Section speed limit value information issues car-mounted terminal in time, and car-mounted terminal passes information to ECU after receiving section speed limit value.
ECU (Electronic Control Unit) electronic control unit, also known as " car running computer ", " vehicle-mounted computer " etc..
It is then automobile specified microcomputerized controller from purposes, control engine operation.
Car-mounted terminal is installed with vehicle, can return data to the network platform, transmit control command to ECU.
Information is issued vehicle-mounted (GPS) terminal by mobile base station by the network platform, and car-mounted terminal and the network platform can be real
Existing information exchange.It is one of mode more commonly used at present.The available vehicle location of such mode starts control command to vehicle
Mounted terminal etc. signal interaction.(realize and section speed limit value be transmitted to ECU)
Preferably, car-mounted terminal is GPS terminal.
Preferably, ECU is passed information to by CAN bus after car-mounted terminal reception atmospheric humidity.
Step 2 after ECU obtains local section speed limit value information, participates in practical control and calculates, control diesel engine operation.
To sum up, it should be based on vehicle location based on the method for road speed limit target value restricted speed, the speed limit value of road was moved
State is sent to engine, realizes the received speed limit target dynamic of ECU, and vehicle can be responded according to section speed limit Intelligent target,
Overspeed of vehicle is avoided, the safety is improved, guarantee driving safety.
The aforementioned description to specific exemplary embodiment of the invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining specific principle of the invention and its actually answering
With so that those skilled in the art can be realized and utilize a variety of different exemplary implementation schemes of the invention and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
