Abstract
The utility model discloses a downslope speed control device for an automobile, which comprises a level sensor, an automobile speed sensor, a singlechip, a speed changer, an alarm and an automobile ECU (electronic control unit), wherein the level sensor and the automobile speed sensor are connected with the singlechip; an output end of the singlechip is connected with the automobile ECU; and another output end of the singlechip is connected with the speed changer and the alarm in sequence. The device can monitor a gear state of an automobile in real time when the automobile is downslope, reminds a driver of not sliding at a neutral gear through the alarm, and automatically controls the vehicle to slow down when the automobile speed is excessive. The device is high in practicability and reliability, simple in structure and convenient to mount, is suitable for being mounted on various motor vehicles, thereby ensuring the driving safety of a driver.
Description
Technical field
The utility model belongs to field of automobile safety, relates in particular to a kind of automobile downhill speed control unit.
Background technology
Because people's living standard improves, the quantity of automobile also increases day by day, and the speed of getting on the car at express highway is surprising; Particularly in automobile downhill, a lot of drivers usually select neutral to travel for fuel-efficient, and along with the increasing of the gradient, speed can sharply increase like this, and at this moment the driver often selects brake pedal slowly to brake to slow down the speed of a motor vehicle.But when the increase of slope length, and brake pedal is in friction phase always, and the brake shoe brake cheek sector-meeting is sharply generated heat, and when temperature acquired a certain degree, braking automobile often lost the function of braking very soon, can be easy to cause like this traffic accident.
Summary of the invention
The purpose of this utility model is: propose a kind of safety control, this device can prevent that chaufeur from hanging neutral when descending, simultaneously the moving velocity of automobile is remained in the scope of a safety, guarantees that chaufeur can the safe driving automobile.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved:
A kind of automobile downhill speed control unit, comprise horizon sensor, car speed sensor, micro controller system, change-speed box, annunciator and automobile ECU, wherein, horizon sensor and car speed sensor connect respectively micro controller system, a mouth of micro controller system connects automobile ECU, and another mouth is connected with annunciator with change-speed box successively.
The utility model also has following other technologies characteristics:
Described horizon sensor adopts the LE-60 sensor.
Described car speed sensor adopts CN65M/NS43NCT1 photo-electric car speed sensor.
Described micro controller system adopts the STC5204AD micro controller system.
Described annunciator is buzzer phone.
This device can real-time monitor the vehicle shifting state when automobile downhill, by annunciator reminding driver neutral position sliding not, and automatically control car retardation when the speed of a motor vehicle is too high.This device is practical, and reliability is high, and is simple in structure, easy for installation, is fit to be arranged on all kinds of self-propelled vehiclees, guaranteed the traffic safety of chaufeur.
Description of drawings
Fig. 1 is structure connection diagram of the present utility model.
Below in conjunction with the drawings and specific embodiments, service condition of the present utility model is described further.
The specific embodiment
As shown in Figure 1, the utility model is a kind of automobile downhill speed control unit, comprise horizon sensor, car speed sensor, micro controller system, change-speed box, annunciator and automobile ECU, wherein, horizon sensor and car speed sensor connect respectively micro controller system, a mouth of micro controller system connects automobile ECU, and another mouth is connected with annunciator with change-speed box successively.Horizon sensor adopts highly sensitive LE-60 sensor, for detection of judging whether vehicle is in the descending state; Car speed sensor adopts the high CN65M/NS43NCT1 type photo-electric car speed sensor of accuracy rate, detects vehicle current driving speed; Change-speed box is automobile self change-speed box; Micro controller system adopts the STC5204AD micro controller system, is used for sensor signal is judged and processes; Annunciator is buzzer phone.
When running car during to the descending highway section, vehicle just can run-off the straight, and horizon sensor passes to micro controller system with signal; Micro controller system learns that vehicle is in when getting off state, and the change-speed box by vehicle judges the vehicle current neutral position of whether being in, if the automobile current neutral position of being in, the Single-chip Controlling annunciator sends alerting signal, and the timely engage a gear of reminding driver is to guarantee safety.If during this time chaufeur is hung into high gear, micro controller system detects automobile by car speed sensor moving velocity is during greater than predefined safety speed, be sent to automobile ECU and send restriction signal, this moment, ECU sent electric impulse signal to the automobile fuel injector, control the fuel charge of fuel injector, reach the purpose of restricting vehicle speed.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connection mode of electronic devices and components as can be known of the technical solution of the utility model.
