Description
Technical field
The utility model is related to a kind of anti-error startup safety control systems of electric vehicle, belong to control technology for electric motor car field.
Background technology
Existing electric vehicle can be such that electric vehicle starts and run after turning on the power switch by handle speed governing, but if
Driver be not seated on the seat or walking process in accidentally have rotated handlebar, will result in electric vehicle error starting, so as to cause
Electric vehicle is scurried out with the speed that is exceedingly fast, and causes safety accident；Or driver forgets in the case of closing key power supply sometimes, covets
The children of object for appreciation touch acceleration handle, will also result in electric vehicle error starting, therefore there are the presence of existing electric vehicle control system
Some potential safety problems.
Invention content
In view of the deficiencies of the prior art, the utility model provides a kind of anti-error startup safety control system of electric vehicle, avoids
When electric vehicle power sources are opened, due to misrouting motor-car the safety accident for causing vehicle launch and causing, the safety of electric vehicle is improved
Performance.
To achieve the above object, the anti-error startup safety control system of a kind of electric vehicle, including MCU controllers, anti-error startup
Anti-error enabling signal is delivered to by signaling switch, brshless DC motor, accumulator and speed control crank, anti-error startup signaling switch
Speed-regulating signal is delivered to MCU controllers by MCU controllers, speed control crank, and MCU controllers export power enable signal to brushless straight
Galvanic electricity machine, the brshless DC motor signal that will move in turn are delivered to MCU controllers, and MCU controllers pass through power switch and stored with electric vehicle
Battery signal be connected, anti-error startups timer is connected with MCU controllers, power switch opening and nothing move in turn signal when, tamper-resistant
Dynamic timer starts timing, and when reaching setting duration, power output enable signal disconnects；MCU controllers detect anti-error startup
When detecting speed-regulating signal while signal, MCU controllers discharge anti-error ring off signal, and MCU controllers output power output makes
Can signal to brshless DC motor and respond the speed-regulating signal of speed control crank.
MCU controllers open anti-error signaling switch amount detection function, and detect unlatching and the pass of anti-error switching signal in real time
Closed state, and control the opening and closing opportunity of power enable signal.When MCU controllers detect vehicle without move in turn signal and
In the case that power supply is still kept it turning on, start timer timing, timing time to power output enable signal is cut off immediately, at this time
Handle acceleration signals is invalid, controller preferential answering anti-misoperation signal and no longer respond handle speed-regulating signal；It is detected when simultaneously
When to anti-error enabling signal and speed-regulating signal, system is considered anti-false dismissal, and controller is absorbed in response handle speed governing letter at this time
Number, it prevents driver from forgetting in the case of closing key power supply, misroutes the danger that dynamic speed control crank causes vehicle launch, improve
The security performance of electric vehicle；After vehicle power output is normal, in the state that electric lock is kept effectively, anti-error startup signaling switch loses
Effect, even if being switched on or switched off during driving does not influence vehicle use and power output, therefore it is normal not interfere with driver
It drives.
Further, it is anti-error start timer setting when it is 10 to 20 seconds a length of.The timer can be manually set, excellent
It is 10 to 20 seconds to select setting range.
Further, while MCU controllers detect anti-error enabling signal, handle speed-regulating signal reaches operation voltage,
MCU controllers export power output enable signal.
The utility model can be effectively prevent by the logic judgment of function of tonic chord controller plus anti-error startup signaling switch
The danger of electric vehicle error starting improves the security performance of electric vehicle.
Description of the drawings

As depicted in figs. 1 and 2, the anti-error startup safety control system of a kind of electric vehicle, including MCU controllers, anti-error startup
Anti-error enabling signal is delivered to by signaling switch, brshless DC motor, accumulator and speed control crank, anti-error startup signaling switch
Speed-regulating signal is delivered to MCU controllers by MCU controllers, speed control crank, and MCU controllers export power enable signal to brushless straight
Galvanic electricity machine, the brshless DC motor signal that will move in turn are delivered to MCU controllers, and MCU controllers pass through power switch and stored with electric vehicle
Battery signal be connected, anti-error startups timer is connected with MCU controllers, power switch opening and nothing move in turn signal when, tamper-resistant
Dynamic timer starts timing, and when reaching setting duration, power output enable signal disconnects；MCU controllers detect anti-error startup
When detecting speed-regulating signal while signal, MCU controllers discharge anti-error ring off signal, and MCU controllers output power output makes
Can signal to brshless DC motor and respond the speed-regulating signal of speed control crank.
MCU controllers open anti-error signaling switch amount detection function, and detect unlatching and the pass of anti-error switching signal in real time
Closed state, and control the opening and closing opportunity of power enable signal.When MCU controllers detect vehicle without move in turn signal and
In the case that power supply is still kept it turning on, start timer timing, timing time to power output enable signal is cut off immediately, at this time
Handle acceleration signals is invalid, controller preferential answering anti-misoperation signal and no longer respond handle speed-regulating signal；It is detected when simultaneously
