Description
Technical field
The invention belongs to vehicle technology field, and in particular to a kind of electric car can be timely and smoothly accelerated.
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.So, existing electric car is difficult to accomplish any
When needs in time and smoothly accelerate.
