Description

Energy saving environment protecting electric vehicle VCU manages circuit
Technical field
The utility model is related to technical field more particularly to a kind of energy saving environment protecting electric vehicle VCU management circuits.
Background technology
Electric car is using accumulator as energy source, by components such as controller, motor, converts electrical energy into machinery Movable vehicle.The motor of electric car is equivalent to the engine of conventional motor vehicle, and accumulator is equivalent to original fuel tank, control Device processed then with original controller class seemingly.Since the electric energy that electric car is consumed is secondary energy sources, wind energy, water can be derived from The various ways such as energy, thermal energy, solar energy are a kind of vehicles of environmental protection.
Electric car on the market is generally using DC permanent magnet motor at present, and DC permanent magnet motor is according to whether using electricity Brush commutation can be divided into two kinds of brush motor and brushless motor, and brush motor is the main product of direct current generator, most at present Electric car all drives wheel using brush motor.However, brush motor energy-flux density is relatively low and torque is small, work efficiency compared with Low, commutator is easily damaged, it is difficult to be met the needs of users.
In addition, start and stop, speed adjusting of the existing electric car using Single Controller control electric car, and control turns simultaneously The real-time display and lighting system of the operation data such as speed, temperature protect system, alarm system etc., since controller is controlled Device and task it is more, larger computational burden is brought to controller, and has seriously affected the arithmetic speed and effect of controller Energy.Meanwhile I/O pins are less possessed by single controller, inconvenience further expands the function of electric car.
In summary, the existing technology has inconveniences and defects in actual use, so it is necessary to be improved.
Utility model content
For it is above-mentioned the defects of, the purpose of this utility model is to provide a kind of energy saving environment protecting electric vehicle VCU manage circuit, It can improve control efficiency.
To achieve these goals, the utility model provides a kind of electric car VCU management circuit, electric car VCU management electricity Road, which is characterized in that including:Main control module and secondary control module;
The main control module connects control E-Gas, temperature detecting module and brake by CAN bus;
The secondary control module connects control display module, alarm module and gear control module by CAN bus;
Switching control module is connected between the main control module and secondary control module, the CAN bus is also connected with responding Time detecting module, response time detection module connection main control module.
The utility model provides a kind of electric car VCU management circuit, including:Main control module and secondary control module;Institute It states main control module and control E-Gas, temperature detecting module and brake is connected by CAN bus;The secondary control module leads to Cross CAN bus connection control display module, alarm module and gear control module;The main control module and secondary control module it Between connect switching control module, the CAN bus is also connected with response time detection module, response time detection module connection master Control module.The circuit use master & slave control structure, make the outfit circuit electric car have motor work efficiency it is higher, control The computational burden of device processed is relatively low and control mode flexibly, convenient for extending the function of electric car the advantages of.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.
Fig. 1 shows the modular structure for the vehicle electric circuitry that the utility model embodiment is provided, for convenience of description, only Show with the relevant part of the utility model, details are as follows:
The electric car VCU management circuits of the utility model, including:Main control module and secondary control module;
Main control module connects control E-Gas, temperature detecting module and brake by CAN bus;
Secondary control module connects control display module, alarm module and gear control module by CAN bus;
Switching control module is connected between main control module and secondary control module, the CAN bus is also connected with the response time Detection module, response time detection module connection main control module.
Need what is illustrated, the functional structure that main control module and secondary control module are controlled can be extended by CAN bus. Main control module I/O resource is solved the problems, such as whereby.
In addition, based on the utility model by response time detection module, detection pilot controller controls the sound of each component Between seasonable, by taking display module, alarm module and gear control module as an example, have one after the signal of secondary control module is received Section response time, time detecting module can detect the time and feed back to main wiping module.Since main control module and auxiliary control The difference of module configuration, the response time in control can difference.If more urgent scene, such as descending, it Ask the response time very short, main control module can be weighed by the switching control of switching control module, i.e., shown by master control module controls Module, alarm module and gear control module.Certainly, under general scene, can control be switched to auxiliary control mould again Block.
In addition, main control module may be employed the model DSPIC33FJ32MC204's of MICROCHIP companies of U.S. production Chip is formed during combining necessary periphery as main control chip.Not only the speed of service is fast for it, data-handling capacity is strong, but also valency Lattice are cheap, control is flexible, thus are more suitable for the control of brushless motor.Master board is mainly used for realizing SVPWM (Space Vector Pulse Width Modulation, space vector pulse width modulation) key jobs such as control algolithm and system protection.
The chip of the model PIC16F1933 of MICROCHIP companies production may be employed as master control in secondary control module Chip is formed during combining necessary periphery.It is communicated between main control module and secondary control module using agreement.Auxiliary control Mainly for the treatment of the real time data of vehicle electric circuitry, output valve display screen may be simultaneously used for molding block with being shown Auxiliary control, if speed threshold selects, sound-light alarm etc..
The computational burden of controller is not only reduced using master & slave control structure, is also had the function of convenient for extension electric car The advantages of.
In conclusion the utility model provides a kind of electric car VCU management circuit, including:Main control module and auxiliary are controlled Molding block;The main control module connects control E-Gas, temperature detecting module and brake by CAN bus;The auxiliary Control module connects control display module, alarm module and gear control module by CAN bus;The main control module and auxiliary Switching control module is connected between control module, the CAN bus is also connected with response time detection module, response time detection Module connects main control module.The circuit uses master & slave control structure, and the electric car of the outfit circuit is made to have the work of motor The advantages of efficiency is higher, the computational burden of controller is relatively low and control mode is flexible, convenient for extending the function of electric car.Certainly, The utility model can also have other various embodiments, in the case of without departing substantially from the utility model spirit and its essence, be familiar with this The technical staff in field works as can make various corresponding changes and deformation according to the utility model, but these corresponding changes and change Shape should all belong to the scope of the claims appended by the utility model.
