Abstract
The utility model discloses an electronic car speed governor which comprises a pedal sensor, a main controller, an electronic control unit, a keyboard control unit, a sound alarm unit, a storage unit and a display unit. The keyboard control unit is connected with a main controller, the pedal sensor is connected with an input end of the main controller, and an output end of the main controller is respectively connected with an electronic controller, the sound alarm unit, the storage unit and the display unit. The electronic car speed governor can collect electric signals of the pedal sensor to achieve the running speed of a car and compares the running speed with the preset highest car speed to judge whether the car is overspeed. In the overspeed situation, the speed of the car can be limited. The speed governor is flexible to install, cannot destroy integrity and reliability of the car, can effectively solve the problem of car overspeed and greatly reduces occurrence rate of terrible traffic accidents.
Description
Technical field
The utility model belongs to the motor vehicle safe driving field, is specifically related to a kind of electronic car velocity limiter.
Background technology
Along with the fast development of economy, the city automobile recoverable amount constantly rises, and China has hundreds thousand of traffic accidents to occur every year, if automobile overspeed governor can be popularized, will reduce the traffic accident incidence, thereby retrieve unnecessary Loss of Life and property.Velocity limiter generally is divided into two kinds: a kind of is to send voice alarm when overspeed of vehicle, reminds the driver to slow down; Another kind is after vehicle surpasses restriction speed, to send instruction by ECU, forces to control car retardation.By contrast, the second can more effective less traffic accident.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is, a kind of effectively restricted speed is provided, and reduces the electronic car velocity limiter of traffic accident incidence.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of electronic car velocity limiter, comprise pedal sensor, master controller, electronic control unit, Keyboard Control unit, audio alert unit, memory cell and display unit, the Keyboard Control unit is connected with master controller, pedal sensor is connected with the input end of master controller, and the mouth of master controller is connected with display unit with electronic controller, audio alert unit, memory cell respectively.
The utility model also has following technical characterstic:
Described master controller adopts the MSP430F169 micro controller system.
Described audio alert unit adopts the ML22865 speech chip with power amplifier.
Described memory cell adopts the 24LC512 memory device.
Described Keyboard Control unit comprises that governor switch key, numerical value increase key, numerical value reduces key and acknowledgement key.
Described display unit adopts LED charactron telltale.
The utility model obtains the speed of operation of automobile by the electric signal that gathers accelerator pedal sensor, by comparing to judge with default maximum speed whether automobile exceeds the speed limit, and in the situation that hypervelocity is carried out speed limit to vehicle.This velocity limiter is flexible for installation, does not destroy integraty and the reliability of automobile, can effectively solve the overspeed of vehicle problem, greatly reduces the incidence of pernicious traffic accident.
Description of drawings
Fig. 1 is annexation schematic diagram of the present utility model.
Below in conjunction with drawings and Examples, particular content of the present utility model is described in more detail.
The specific embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, a kind of electronic car velocity limiter, comprise pedal sensor, master controller, electronic control unit, Keyboard Control unit, audio alert unit, memory cell and display unit, the Keyboard Control unit is connected with master controller, pedal sensor is connected with the input end of master controller, and the mouth of master controller is connected with display unit with electronic controller, audio alert unit, memory cell respectively.Described master controller adopts the MSP430F169 micro controller system.Described audio alert unit adopts the ML22865 speech chip with power amplifier.Described memory cell adopts the 24LC512 memory device.Described Keyboard Control unit comprises that governor switch key, numerical value increase key, numerical value reduces key and acknowledgement key.Described display unit adopts LED charactron telltale.
The utility model is when work, by the Keyboard Control default speed limit higher limit V in unit
max, and with this pre-set velocity higher limit V
maxDeposit memory cell in, this unit is for velocity limiter provides storage space, being used for depositing default speed limit, and provides enough storage spaces to main control unit.Should default speed limit higher limit V
maxExport to telltale through main control unit, show current default speed limit higher limit V
maxFor the safety and the stationarity that guarantee to travel, velocity limiter only could start or close under the state of parking of automobile, if press governor switch in the situation that pedal sensor collects Das Gaspedal action, the audio alert unit sends audio alert; If when not collecting the Das Gaspedal action, then judge whether to be in motoring condition, the 5s time-delay is set, and again pushes button, if still not action of Das Gaspedal is opened velocity limiter, otherwise sent warning, when closing, process is as the same.After starting velocity limiter, pedal sensor reduces impedance with the voltage signal that collects through op amp, is input in master controller, utilizes 12 ADC of master controller inside to complete analogue to digital conversion, obtains moving velocity V
a, with V
aWith pre-set velocity higher limit V
maxCompare, if V
a＜V
max, not exceed the speed limit, this moment, master controller was transferred to electronic control unit with the electric signal process of pedal sensor; If V
a＞V
max, be in overspeed condition, the constant pre-set velocity upper limit V of master controller output
maxGive electronic control unit, realize speed limiting function.
