Abstract
The invention discloses a road grade detection device for motor vehicles, comprising a Hall element and a single pendulum structure. Magnetic steels are arranged at the lower end of the single pendulum structure along the longitudinal direction; and the Hall element is connected with a motor vehicle control unit and is correspondingly arranged at the lower part of the single pendulum together with the magnetic steels. In the invention, the Hall element and the single pendulum structure which is opposite to the Hall element and can longitudinally swing along a motor vehicle are utilized, when the motor vehicle is uphill or downhill, the magnetic steel is enabled to swing relative to the Hall element by using the action of gravity component forces, the Hall element detects magnetic changes and transmits signals to a control unit, the control unit obtains the traveling grade, the uphill degree and the downhill degree of the motor vehicle through calculation, controls and distributes power according to data so that the driving force of the motor vehicle is adjusted along with the change of the working condition. Therefore, the working efficiency of an engine is improved on the basis of saving energy, and the purposes of energy conservation, emission reduction and environmental protection are achieved.
Description
Technical field
The present invention relates to a kind of automotive component, particularly a kind of road grade detection device for motor vehicles.
Background technology
Self-propelled vehicle make people live in indispensable riding instead of walk and transportation means.In the prior art, self-propelled vehicle all is by governor handle or acceleration pedal direct control speed basically, or adopts manual mechanical automatic transmission mode to realize speed change.Usually can cause operation and garage's situation not to match, cause the engine installation fluctuation of service.
In the drive routine, navigating mate is according to the gradient of road, to the self-propelled vehicle power-assisted operation of slowing down, by the driver under the situation of not knowing resistance to motion, only rule of thumb operate the transmission system of control, driving engine or motor power (output) can occur and the travel situation does not match, cause the waste of the energy, and be unfavorable for environmental protection.For autonomous cruise speed system, can only control the speed of a motor vehicle according to the resistance to motion situation, and can't directly detect condition of road surface (descending or upward slope).
Thereby, need a kind of device that condition of road surface is detected, the accurate road conditions that travelled of machines motor-car (going up a slope or descending), and the data that detected are reached the self-propelled vehicle control unit is controlled power according to these data and is distributed by control unit.
Summary of the invention
In view of this, the invention provides a kind of road grade detection device for motor vehicles, accurately machines motor-car running gradient and ascents and descents, and the data that detected are reached the self-propelled vehicle control unit are controlled power according to these data and are distributed by control unit.
The objective of the invention is to be achieved through the following technical solutions: comprise Hall element and single pendulum structure, described single pendulum structure lower end edge vertically is provided with magnet steel, described Hall element and self-propelled vehicle control unit link to each other and with the corresponding single pendulum bottom that is arranged on of magnet steel.
Preferably, comprise also pedestal is set that described device pedestal is provided with column, described single pendulum structure is arranged on the column, and Hall element is arranged on base-plates surface.
Preferably, magnet steel is embedded in the single pendulum bottom, and the bottom outer rim is cambered outwards circular arc vertically;
Preferably, described column is two and is set up in parallel that the single pendulum structure comprises simple pendulum arm and the weight that is arranged on the simple pendulum arm lower end, and simple pendulum arm is arranged between two columns by the single pendulum axle, and described magnet steel is arranged on the weight lower end.
Beneficial effect of the present invention: road grade detection device for motor vehicles of the present invention, adopt Hall element and with it relatively and can be along the single pendulum structure of self-propelled vehicle longitudinal oscillation, during uphill/downhill, utilize the effect of partical gravity, make the relative Hall element swing of magnet steel, Hall element detects magnetic force change and signal is reached control unit, control unit is by calculating self-propelled vehicle institute's running gradient and ascents and descents, and according to these data power is controlled and distributed by control unit, the propulsive effort of self-propelled vehicle is adjusted along with the variation of operating mode, so that on the basis of energy savings, improve efficiency of engine, reach the purpose of energy-saving and emission-reduction and environmental protection.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 and Fig. 2 are structural representation of the present invention.
The specific embodiment
Accompanying drawing is a structural representation of the present invention, as shown in the figure: the road grade detection device for motor vehicles of present embodiment, comprise Hall element 2 and single pendulum structure, single pendulum structure lower end edge vertically is provided with magnet steel 3, described Hall element 2 and self-propelled vehicle control unit link to each other and with the magnet steel 3 corresponding single pendulum bottoms that are arranged on;
Present embodiment also comprises device pedestal 5, and device pedestal 5 is provided with column 4, and described single pendulum structure is arranged on the column 4, and Hall element 2 is arranged on device pedestal 5 surfaces; Adopt the structure of device pedestal 5 and column 4, make apparatus structure simply compact, be easy to install and make;
In the present embodiment, column 4 is two and is set up in parallel that the single pendulum structure comprises simple pendulum arm 11 and the weight 1 that is arranged on simple pendulum arm 11 lower ends, and simple pendulum arm 11 is arranged between two columns 4 by single pendulum axle 12, and described magnet steel 3 is arranged on weight 1 lower end; Two pillar constructions are set, are beneficial to the stability when keeping the swing of single pendulum structure, thereby guarantee that testing result is accurate;
During use, will install along self-propelled vehicle vertically (cephlad-caudal) be installed on the self-propelled vehicle, single pendulum is swung with slope change, and reaches control unit by the Hall element detection signal;
Among the application, vertically all refer to the cephlad-caudal of self-propelled vehicle.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
