Abstract
The present invention relates to an automatic speed controller for automobile. Said controller mainly is formed from sensor, voltage amplifier, comparator, logic circuit and trigger. It can automatically control speed according to the speed of automobile and distance from the automobile to its front obstacle.
Description
1. technical field that the present invention belongs to
The present invention is a kind of control setup.It utilizes the speed of Eltec automatic guidance automobile.
2. Fa Ming background
As everyone knows, the driving safety of automobile depends primarily on speed, and at present the speed of automobile be by chaufeur according to vehicle condition, road conditions, meteorological optical range, volume of traffic, flow of traffic speed, environment, control by rule of thumb.This will under the factor condition of poor such as fitness, drive over the speed limit because of chaufeur in technical experience, causes the dangerous of automobile to travel.
3. Fa Ming purpose
The invention reside in the speed automatic controller that a kind of automobile is provided.Sort controller can be according to the distance of the encumbrance in the speed of automobile and the place ahead and automobile and the automatic guidance speed of a motor vehicle, thereby has improved the driving safety of automobile greatly.
4. Fa Ming content and optimum implementation
Accompanying drawing is the embodiment of the present invention at the automatic speed changing automobile.
" 10 " among the figure are car speed sensors, and the speed of a motor vehicle is converted to the vdc that is linear, amplify through " 12 " voltage amplifier, send into an end of " 18 " comparator." 14 " are rang sensors, the distance of encumbrance and automobile is converted to the vdc that is linear, amplify through " 16 " voltage amplifier, send into the other end of " 18 " comparator, relatively computing is carried out by " 20 " decision circuit in the back, again by " 22 " binary pair output control signal, the reference device in control " 24 " automatic transmission with hydraulic torque converter electronic control package.
In addition, " 18 " comparator and " 20 " decision circuit, the relation of two input ends of its regulation and " 20 " logic circuit output end: when an input terminal voltage was V, when another input end was equal to or less than V, " 20 " decision circuit was output as low level 0.Otherwise, output high level 1.
To the automatic speed changing automobile of formation like this, the work when quickening describes below:
During car acceleration, car speed sensor converts the speed of a motor vehicle to be linear vdc, sends into comparator through voltage amplifier.Simultaneously, rang sensor also converts the distance of encumbrance and automobile to be linear vdc, sends into comparator through voltage amplifier.
When the speed of a motor vehicle/distance was in predefined scope, promptly an end of comparator was V, and when the other end was equal to or less than V, by logic operation output low level 0, binary pair was not worked, so do not change the reference device in the automatic transmission with hydraulic torque converter electronic control package.Automobile carries out gear shift by original shift point.
When the speed of a motor vehicle/distance was not in predefined scope, promptly an end of comparator was V, and the other end is during greater than V, by logic operation output high level 1, flip-flop operation, then change reference device in the automatic transmission with hydraulic torque converter electronic control package, promptly changed shift point and automatic guidance the speed of a motor vehicle.
5. the effect of inventing
As described above, utilize the present invention. Because stipulated the distance of automobile and bar From a timing, the speed of a motor vehicle is the highest can only be in setting or in less than the scope of setting, so automobile Can drive safely.
6. the simple declaration of accompanying drawing
Accompanying drawing is the wherein circuit block diagram of a kind of embodiment of expression the present invention.
Claims (2)
1 one kinds of speed automatic controllers that are used for automobile, this controller are mainly by sensor, voltage amplifier, and comparator, decision circuit is formed.Sensor converts the distance of the speed of automobile and encumbrance and automobile to corresponding electric signal respectively.Through amplifying, relatively, logic operation is by binary pair output control signal.
2 a kind of speed automatic controller that is used for automobile as claimed in claim 1, wherein the comparison means of forming by comparator and decision circuit.It is characterized in that: it can handle the comparison of two or more variation voltage.
