Description
Technical field
The invention belongs to vehicle technology field, and in particular to one kind can point out speed control crank torsion angle close to power
Start to control the electric car at angle.
Background technology
The speed governing of electric car is that speed governing is carried out by speed control crank is reversed, and so-called speed governing is substantially regulation electric car electricity
Machine exports power（Power）Size, the windup-degree of speed control crank（Hereinafter referred to as torsion angle）It is bigger, the power of motor output
It is bigger, during manufacturer's design electric car, in order to avoid electric car is in static mistiming vibration, beginning of the speed control crank in speed governing
Stage design has the torsion angle of the unpowered output of larger motor, and power was just reached after speed control crank turns round this angle
Start to control a little（Corresponding torsion angle claims power to start to control angle）, motor just begins with power output.From speed regulating control principle, it is exactly
Say the speed regulating control input of controller for electric vehicle（Typically single-chip simulation amount input）It is designed with a power（Power）
Voltage is started to control, speed control crank, as torsion angle increases, the output voltage of the speed governing Hall element in handle are reversed since static
Just gradually increase, dynamic output is begun to when the output voltage of Hall element reaches motor after power starts to control voltage.From static
Start to reverse speed control crank, the torsion angle of unpowered output claims unpowered angle.
But, the presence just because of unpowered angle can make driver can not know that power starts to control angle there, so that band
Carry out many problems.For example, when electric car is started to walk, driver often reverses speed control crank can quickly lead to faster speed
Cross unpowered angle and reach power and start to control angle, but because driver does not know that power starts to control angle there, it is impossible to close to power
Just stop when starting to control angle and then reverse speed control crank at leisure again can smoothly start to walk, but be easy to just exceed quickly
Power starts to control angle, and causing electric car to start to walk, power is excessive, and electric car accelerates suddenly（With having clutch and soniferous engine
Motorcycle compares, and this is electric car defect）.And for example, in the process of moving, when accelerating again after electric motor vehicle sliding or after brake
When accelerating again（Now speed control crank has been twisted back into unpowered angular zone）, because driver does not know that power starts to control angle at that
In, when torsion speed control crank is intended to be accelerated, also it is easy to just start to control angle more than power quickly, causes electric car to accelerate dynamic
Power is excessive, and electric car accelerates suddenly, easily causes accident.Some drivers accelerate suddenly in order to avoid electric car, just slowly
Speed control crank is reversed, allows electric car to be slowly into power and starts to control a little, but such operating method can be because speed control crank passes through
The overlong time at unpowered angle and can not as soon as possible start to walk or accelerate in time.
The content of the invention
For the shortcoming of above-mentioned electric car, it is an object of the invention to provide one kind speed control crank torsion angle can be pointed out close dynamic
Power starts to control the electric car at angle, and electronic related technologies are used on electric car, and close to power angle is started to control in the torsion angle of speed control crank
When send cue so that drive electric car when can accelerate smoothly, in time.
What the present invention was realized in：A kind of electric car that speed control crank torsion angle can be pointed out to start to control angle close to power, bag
Include speed governing Hall element and the controller for electric vehicle in the speed control crank and handle of electric car, the speed regulating control of controller for electric vehicle
Input is designed with a power and starts to control voltage so that speed control crank exist in the incipient stage of speed governing larger motor without
The torsion angle of power output, when speed control crank turns round this angle, the output voltage of speed governing Hall element got to electric car
The power of controller starts to control voltage, and motor just begins with power output, and now the torsion angle of corresponding speed control crank claims power to rise
Control angle, it is characterised in that equipped with one the torsion angle of speed control crank can be pointed out to start to control the cue circuit at angle close to power on electric car,
The cue circuit is less than and moving close to controller for electric vehicle speed regulating control input in speed governing hall element output voltage
Power sends cue when starting to control voltage.
