Description
Technical field
Field of automobile safety is the utility model is related to, more particularly, to a kind of limiting vehicle speed system.
Background technology
With the continuous lifting of technology, material and pavement conditions, Automobile Design travel speed also improves therewith.But with vapour
Constantly soaring and more sophisticated the driving environment of car ownership, overspeed of vehicle traveling have become the first inducement of traffic accident.
Under the background, people begin to focus on the safety problem of vehicle traveling.While various vehicle active safety features emerge in an endless stream,
Various countries start to put into effect relevant regulation, and Vehicle Speed is limited, and passive ensures vehicle and the safety of pedestrian.Herein
In the case of, car overspeed governor arises.Traditional limiter of speed is simple in structure, and function is single, and simple judges speed.
After speed reaches preset vehicle speed value, stop oil spout by force, stop engine power output, decline speed；When speed reduces
To after preset lower limit value, engine recovers fuel feeding, speed lifting.So repeatedly, speed is limited within a certain range ripple up and down
It is dynamic.Traditional limiter of speed not only during speed limit and releasing speed limit, there are serious impact sense, reduces drivability, and
And the speed limit by force under some complex working conditions overtaking other vehicles such as highway, bring derivative danger.
The content of the invention
The utility model aim is to provide a kind of limiting vehicle speed system that can carry out current driving operating mode intelligent decision
System.
To achieve the above object, the utility model can take following technical proposals：
Limiting vehicle speed system described in the utility model, including engine control module；The engine control module
Signal output part is electrically connected with the signal input part of engine, and the signal input part of engine control module is with being arranged on console
On the signal output part of adjustable limiter of speed be electrically connected, the signal input part of the adjustable limiter of speed is believed with the speed of instrument respectively
Number output terminal and the throttle signal output terminal of efp output are electrically connected.
Switch and acoustic-optic alarm are provided with the adjustable limiter of speed.
The utility model advantage is that current driving operating mode can be carried out intelligent decision, selective progress speed limit
System, avoids the safety problem that limited speed belt comes by force；This kind of control mode meets the requirement to Control for Speed Limitation in European Union ECE89.Can
Adjust limiter of speed to send torque request to engine by engine control module, engine torque output is maintained at one with speed
Fixed value, speed caused by avoiding conventionally employed oil-break speed limit back and forth fluctuates and traffic blows, ensures safety during Control for Speed Limitation
Property and comfort, while it possesses the features such as cost is low, easy for installation, easy to use.
Brief description of the drawings
Fig. 1 is the schematic block circuit diagram of the utility model.
Embodiment
As shown in Figure 1, limiting vehicle speed system described in the utility model, including engine control module；The engine
The signal output part of control module is electrically connected with the signal input part of engine, and the signal input part of engine control module is with setting
The signal output part for putting adjustable limiter of speed in the car is electrically connected, the signal input part of the adjustable limiter of speed respectively with instrument
Speed signal output terminal and the throttle signal output terminal of efp output are electrically connected.
When driver presses the ON/OFF keys of adjustable limiter of speed, limiter of speed function is opened.ON/OFF keys are pressed again, or are opened
Fiery Switching Power Supply is closed, and adjustable limiter of speed function is closed.
When the violent accelerator pedal of driver, the throttle signal curve graded of efp output is sentenced higher than built-in
Determine threshold value, be then determined as that driver such as overtakes other vehicles at the anxious acceleration demand, adjustable limiter of speed does not intervene engine torque at this time,
Vehicle normally gives it the gun；Driver's accelerator releasing or steady throttle drive afterwards, and efp output signal curve gradient is born
Change or variable gradient be less than built-in threshold value, then are determined as that driver completes urgency acceleration demand, then adjustable limiter of speed is to engine
Control module sends torque request.
When driver is accelerated with small throttle, efp output signal curve graded is less than built-in decision threshold
Value, then it is normally travel to be determined as vehicle, then adjustable limiter of speed sends torque request to engine control module.
After engine control module receives torque request, it will perform and control the torque output of engine, vehicle is existed
Fixed turn round drives safely under at the uniform velocity state.
When because inertia, descending road conditions and it is anxious accelerate operation, when speed is higher than speed limit threshold value 3Km/h, adjustable limiter of speed will be into
Row sound-light alarm, reminds driver to carry out deceleration driving.
After limiting vehicle speed, speed is less than threshold limit, then adjustable limiter of speed releases Control for Speed Limitation.
When driver has interim cancellation Control for Speed Limitation demand, CANCEL keys are pressed, adjustable limiter of speed can be made temporarily to shield
Control for Speed Limitation, presses CANCEL keys, then activates Control for Speed Limitation again.
By above specific embodiment, vehicle traveling can be made to reach following proposal target：
1st, when speed limit does not trigger, it is impossible to influence normal gas pedal and accelerate operation.
2nd, driver can be directly observed limiting vehicle speed number threshold value, and convenient operation；
3rd, driver should be able to carry out increase and decrease adjustment by corresponding setting device to limiting vehicle speed threshold value；
4th, under specific operation, by accelerating operation speed is higher than speed limit threshold value by force；
5th, in the case where opening adjustable limiter of speed, it can activate or shield at any time speed limiting function.
