The operating efficiency of vehicle.Therefore new requirement it is also proposed to the control aspect of industrial vehicle.
Existing speed-limiting proposal is to realize speed limit using the stroke of limitation E-Gas, i.e., E-Gas is carried out hard
It is spacing.This speed limit mode has a drawback in that：When carrying out hard spacing to E-Gas, when vehicle carries out handling operation, hair
Motivation can not reach peak power section, and the operating efficiency of vehicle is reduced while speed limit.
Utility model content
The purpose of this utility model is to provide a kind of Control for Speed Limitation loop, to ensure vehicle operation while speed limit
Efficiency.
To realize object above, the utility model provides a kind of Control for Speed Limitation loop, including：Battery positive voltage and main power source
One end connection of switch, one end of negative pole and vehicle speed sensor connect, the other end of main power switch respectively with Control for Speed Limitation list
Member connects with Engine ECU, the signal input part of Control for Speed Limitation unit and the other end connection of vehicle speed sensor, signal output part
With the connection of relay one end, the other end of relay and the negative pole of battery connect, the normally closed stationary contact and electronics of relay
Throttle connection, normally closed movable contact is connected with Engine ECU and E-Gas is connected with engine by wire.
Further, the stitch a1 of Engine ECU is connected with the stitch stitch b of Control for Speed Limitation unit, the pin of Engine ECU
Pin b1 and E-Gas stitch A connections, the stitch c1 and E-Gas of Engine ECU stitch C connections, Engine ECU
The normally closed movable contact of stitch d1 and relay connects, and the stitch e1 of Engine ECU and the negative pole of battery connect；
The stitch a of Control for Speed Limitation unit and the signal output part of vehicle speed sensor connect, the stitch d of Control for Speed Limitation unit with
Battery negative pole connection, the connection of the stitch c of Control for Speed Limitation unit and one end of relay, the normal quiet movable contact of relay with
The stitch B connections of E-Gas.
Compared with prior art, there is following technique effect in the utility model：The utility model in Control for Speed Limitation by returning
Relay, Control for Speed Limitation unit and vehicle speed sensor are added in road, signal input part and the speed of Control for Speed Limitation unit pass
Sensor connection, signal output part and relay connect, and the stitch of the normal quiet movable contact and E-Gas of relay connects, be normally closed dynamic
The stitch of contact and engine connects.In this way, by Control for Speed Limitation unit output level it is high/low come control relay obtain it is electric/
Must not be electric, so as to control open circuit/closure of E-Gas signal circuit.By way of cutting off E-Gas signal line loop come
Reach the purpose of speed limit, compared with limiting mode of the stroke of E-Gas to realize speed limit, this programme is less than speed limit in speed
During value, E-Gas whole can respond, and while ensuring that vehicle is not driven over the speed limit in operation area, ensure that vehicle operation
Operating efficiency.
Brief description of the drawings
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail：
Fig. 1 is a kind of electrical block diagram in Control for Speed Limitation loop in the utility model.
Embodiment
In order to illustrate further feature of the present utility model, refer to below in connection with it is of the present utility model detailed description with
Accompanying drawing.Institute's accompanying drawing is only for reference and purposes of discussion, is not used for being any limitation as the scope of protection of the utility model.
As shown in figure 1, present embodiment discloses a kind of Control for Speed Limitation loop, wherein, the positive pole and main power source of battery 10
One end connection of switch 20, the pin of the other end of main power switch 20 the stitch a1 with engine, Control for Speed Limitation unit 40 respectively
Pin b connections；
The stitch b1 of Engine ECU 70 is connected with the stitch A of E-Gas 60, the stitch c1 and electronics of Engine ECU 70
The stitch C connections of throttle 60, the stitch d1 of Engine ECU 70 are connected with the normally closed movable contact of relay 50, Engine ECU 70
Stitch e1 is connected with the negative pole of battery 10；
The stitch a of Control for Speed Limitation unit 40 is connected with the signal output part of vehicle speed sensor 30, Control for Speed Limitation unit 40
Stitch d is connected with the negative pole of battery 10, the stitch c of Control for Speed Limitation unit 40 and the connection of one end of relay 50, relay
50 other end is connected with the negative pole of battery 10, and the normal quiet movable contact of relay 50 is connected with the stitch B of E-Gas 60.
In actual applications, the present embodiment reaches the principle of speed limit purpose by cutting off the signal line loop of E-Gas
It is：
When vehicle runs beginning, main power switch 20, the stitch a1 and Control for Speed Limitation unit 40 of Engine ECU 70 are closed
Obtain electric.When speed is less than the speed limit that Control for Speed Limitation unit 40 is set, the stitch c output low levels of Control for Speed Limitation unit 40,
The coil of relay 50 must not be electric, and the normally closed stationary contact of relay 50 is in closure state, and E-Gas 60 whole can respond.When
When speed exceedes the speed limit that Control for Speed Limitation unit 40 is set, the stitch c output high level of Control for Speed Limitation unit 40, relay 50
Coil obtains electric, and the normally closed stationary contact of relay 50 disconnects, and the signal line loop open circuit of E-Gas 60, now steps on E-Gas
60 E-Gas 60 do not work, and without response, car speed can not continue to increase engine speed, until speed drops to setting value
Hereinafter, E-Gas 60 can be just again switched on.
When vehicle is out of service, main power switch 20 is disconnected, Control for Speed Limitation loop does not work.
Further, the model of the Control for Speed Limitation unit 40 in the present embodiment is VSMS2016, manufacturer：Only create in Guangzhou
Electronics Co., Ltd., main performance are：With the functions such as speed limit, alarm, reversing prompting, degree of protection IP67.
