Description
Technical field
The utility model relates to a kind of controller for electric vehicle, and specifically a kind of electric cycle driving governor, is particularly useful for driving and the brake control of old electric cycle.
Background technology
The main flow control system that electric cycle field is used is at present U.S. CURTIS, and the DC brush scooter controller of Britain PGDeng company drives the back axle assembly with the brush motor formation of electromagnetic brake.This system possesses the features such as system stability maturation.But owing to adopting brush motor, have brush carbon brush for electric machine easy to wear, the shortcoming such as car load efficiency is not high, and speed is unhappy, controller price height.Also the four-wheel of the control system of useful brushless driving and the scooter of three-wheel in the market, but brushless controller only has driving brachium pontis to carry out PWM modulation, vehicle has driving function, disable motor output when vehicle sliding, and motor is in art skating state, in the time of need to braking, can only brake by mechanical braking mechanism, do not take into full account the elderly and react slowly, control inflexible feature, have poor stability, brake dumbly, control inapplicable the elderly's shortcoming.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of simple in structure, rapid operation safely, possess the electric cycle driving governor of electromagnetism auxiliary brake function, solved car load efficiency not high, speed is unhappy, the shortcomings such as poor stability have also adapted to the elderly and have reacted slowly, control inflexible problem.
The technical solution of the utility model is as follows:
A kind of electric cycle driving governor of the utility model, comprise accelerator, brushless controller, braking device, velocity limiter, brushless motor assembly, brake, it is characterized in that: the signal of accelerator, velocity limiter, braking device connects brushless controller, intelligent chip is housed in brushless controller, brushless controller connects brushless motor assembly and brake, by PWM, regulate and drive brachium pontis and braking brachium pontis, brushless controller drive pattern and the braking mode alternate run of staggering the time.
The utility model provides Maximum speed limit value, braking device speed-slackening signal, brushless motor assembly the are provided location information providing, the intelligent chip in via controller to control by the electric cycle brushless controller that possesses electromagnetism auxiliary brake function according to Acceleration Signal, the velocity limiter of accelerator input, when accelerating, controller is to driving brachium pontis to carry out PWM modulation, produce and drive signal, act in the phase line of brushless motor, control brushless motor assembly and steadily advance or retreat; When slowing down and during braking, controller is to adding PWM modulation in braking brachium pontis, controls braking counter electromotive force current that brushless motor assembly enters motor and feeds back to battery battery is charged, and produces braking mode, and car retardation is stopped; Drive the operation of staggering the time of brachium pontis and braking brachium pontis, in the middle of operation, motor is staggered the time in driving and braking mode; The State-output of vehicle and control system, to status displays, notifies user's information of vehicles at once; The brake disc and the brake that under composite brakig pattern and emergency braking pattern, are contained in motor speed end provide mechanical brake power, guarantee that vehicle safety failure-free stops.
The utility model adopts the electric cycle driving governor with electromagnetism auxiliary brake function, possess electromagnetism auxiliary brake function, when vehicle accelerates, to adapt to the slow mode of Characteristics of Old, accelerate, speed limiter in addition, the different requirements for applicable different the elderlys to maximum speed.Under braking mode, electromagnetic braking pattern and mechanical braking pattern are worked simultaneously.To guarantee the reliability of braking, braking force is constant simultaneously, to guarantee the traveling comfort of drag.In brake mode effect, for safety, accelerator steadily accelerates after need making zero again.There is in addition state indication, a few thing state of prompting vehicle.
The utility model is contained in brake the speed end of brushless motor assembly, this structure only need apply very little lock torque, after gear case deceleration, differential, can on drive wheel, produce the lock torque of transmitting ratio multiple, be applicable to very much weak weak the elderly and use; And simple in structure, without two drive wheels are braked simultaneously.The utility model is compared with existing brushless controller, has electromagnetism auxiliary brake function, starts and brakes steadily, and braking is reliable, can realize gradual braking under normal circumstances without mechanical brake.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of electric cycle driving governor, comprise accelerator 1, brushless controller 5, braking device 2, velocity limiter 4, dc-battery 6, brushless motor assembly 7 and brake 8, it is characterized in that: the signal of accelerator 1, velocity limiter 4, braking device 2 connects brushless controller 5, in brushless controller 5, intelligent chip is housed, brushless controller 5 connects brushless motor assembly 7 and brake 8, by PWM, regulate and drive brachium pontis and braking brachium pontis, brushless controller 5 drive patterns and the braking mode alternate run of staggering the time.
The Acceleration Signal that the utility model is inputted according to accelerator 1 by the electric cycle brushless controller 5 that possesses electromagnetism auxiliary brake function, velocity limiter 4 provides Maximum speed limit value, braking device 2 provides speed-slackening signal, the location information that brushless motor assembly 7 provides, the intelligent chip in via controller is controlled, when accelerating, controller is to driving brachium pontis to carry out PWM modulation, produce and drive signal, act in the phase line of brushless motor, control brushless motor assembly and steadily advance or retreat; When slowing down and during braking, controller is to adding PWM modulation in braking brachium pontis, controls braking counter electromotive force current that brushless motor assembly enters motor and feeds back to battery battery is charged, and produces braking mode, and car retardation is stopped; Drive the operation of staggering the time of brachium pontis and braking brachium pontis, in the middle of operation, motor is staggered the time in driving and braking mode; The utility model brushless controller 5 is also connected with status displays 3, and the State-output of vehicle and control system, to status displays 3, notifies user's information of vehicles at once; The brake disc and the brake 8 that under composite brakig pattern and emergency braking pattern, are contained in motor speed end provide mechanical brake power, guarantee that vehicle safety failure-free stops.
The utility model has three kinds of patterns when braking:
Normal brake application pattern: during braking, only accelerator need be turned down or make zero, controller changes braking mode into, controls motor vehicle is produced to braking force, makes it steadily to slow down or brake.The mechanical brake that is now contained in motor speed end is not worked.Rapid operation under this pattern, mechanical brake is not worked, and the life-span is long.
Composite brakig pattern: during braking, apply a suitable power to braking mechanism, the auxiliary braking of this Time Controller and mechanical brake braking are worked simultaneously, can shorten braking distance by actv., realize emergency.
Emergency braking pattern: when needs emergency braking, fast, firmly to braking mechanism, apply power, though the auxiliary braking of this Time Controller and mechanical brake braking are worked simultaneously, the mechanical brake that is contained in motor speed end plays a major role, and it will make vehicle stop immediately.
