Background technique
Electric car refers to using vehicle power supply as power, with motor driven wheels travel, meets road traffic, security legislation
The vehicle of requirements.Electric car includes including fuel cell car, hybrid vehicle, hydrogen-powered vehicles and the sun
Energy automobile etc., since effect on environment is smaller with respect to orthodox car, its prospects are considered optimistic wildly.
Pure electric automobile speed per hour speed, and starting speed depend on driving motor power and performance, mileages of continuation it
Length depends on the size of vehicle mounted dynamic battery capacity, and the weight of vehicle mounted dynamic battery depends on selecting which kind of power battery such as lead
Acid, zinc carbon, lithium battery etc., their volumes, specific gravity, specific power, specific energy, cycle life are all different.The driving of pure electric automobile
Motor be divided at present DC brush, it is brushless, have permanent magnetism, electromagnetism, then have exchange stepper motor etc., their selection also with vehicle
Configuration, purposes, class are related.In addition the speed regulating control of driving motor also divides step speed regulation and stepless speed regulation, has using electronics tune
Fast controller and point for not having to speed setting controller.Motor has hub motor, inner rotor motor, has single motor driving, more motors
Driving and composition motor driving etc..
In electric car in unexpected acceleration or deceleration, the impact work of electric car, which can mitigate, to be accelerated or subtracts suddenly
The jerking movement effect of vehicle when fast.And the deviation of actual motor speed and non-jerking movement model motor speed is the finger of jerking movement vehicle
Show device, will lead to electromotor velocity oscillation when vehicle jerking movement, to influence motor performance, it is therefore desirable to which a kind of system is done
The pre- vibration come dynamical system when inhibiting vehicle acceleration or deceleration.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of anti-impact of the electric car proposed
Hit system.
To achieve the goals above, present invention employs following technical solutions:
A kind of shock resistance system of electric car, including shock resistance controller and torque drive tampering devic, the shock resistance control
Device processed by motor speed sensor receive actual speed signal, shock resistance controller include timer, rotary speed comparator and
Control unit, shock resistance controller control torque drive tampering devic intervene motor speed.
Preferably, the rotary speed comparator compares basal rate signal and actual speed signal.
Preferably, the transformation period of the timer monitoring motor speed.
Preferably, described control unit is to torque drive tampering devic start-up and shut-down control.
Preferably, the torque drive tampering devic includes firing torque intervention and clutch moment of torque intervention.
Preferably, when the motor accelerates, control unit drives clutch moment of torque intervention.
Preferably, when motor deceleration, control unit drive ignition torque intervention.
The beneficial effects of the present invention are:
The invention enables motor in unexpected acceleration or deceleration suddenly, can in time, automatically offset speed difference, inhibit
Vehicle accelerates or slows down, so that motor is avoided, so that vehicle stabilization is run.
Detailed description of the invention
Fig. 1 is a kind of system diagram of the shock resistance system of electric car proposed by the present invention；
Fig. 2 is a kind of shock resistance controller system structural schematic diagram of the shock resistance system of electric car proposed by the present invention；
Fig. 3 is a kind of system diagram of the torque drive tampering devic of the shock resistance system of electric car proposed by the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-3, the shock resistance system of a kind of electric car, including shock resistance controller and torque drive intervention dress
It sets, shock resistance controller receives actual speed signal by motor speed sensor, and shock resistance controller includes timer, turns
Fast comparator and control unit, shock resistance controller control torque drive tampering devic intervene motor speed, revolving speed
Comparator compares basal rate signal and actual speed signal, and timer monitors the transformation period of motor speed, torque drive
Tampering devic includes firing torque intervention and clutch moment of torque intervention, control unit to torque drive tampering devic start-up and shut-down control,
Torque drive tampering devic includes firing torque intervention and clutch moment of torque intervention, when the motor accelerates, control unit driving
Clutch moment of torque intervention, when motor deceleration, control unit drive ignition torque intervention.
1 in the present embodiment, when motor accelerates suddenly, motor speed sensor detects the increasing of the revolving speed of motor
Add, actual speed signal is transferred to shock resistance controller by motor speed sensor, and shock resistance controller passes through timer
The time of the increased speed change of actual speed is calculated, and compares the speed difference of actual speed and basal rate, root by rotary speed comparator
According to speed difference and shifting time, drives clutch moment of torque intervention to offset speed difference by control unit, vehicle is inhibited to accelerate, from
And when motor is accelerated suddenly, avoid motor.
In the present embodiment 2, when motor slows down suddenly, motor speed sensor detects the drop of the revolving speed of motor
Low, actual speed signal is transferred to shock resistance controller by motor speed sensor, and shock resistance controller passes through timer
The time of the speed change of actual speed reduction is calculated, and compares the speed difference of actual speed and basal rate, root by rotary speed comparator
According to speed difference and shifting time, speed difference is offset by control unit drive ignition torque intervention, inhibits vehicle deceleration, thus
When so that motor slowing down suddenly, motor is avoided.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
