Description
Technical field
The utility model belongs to field of automobile electronic control.
Background technology
Currently, the promotion energetically with country to new-energy automobile, electric vehicle gradually comes into our life, wheel
The advantages that hub motor is simple, power density is high with its structure arrangement is gradually applied to electric vehicle, and it is important to become electric vehicle
Component part.Power, transmission and brake apparatus are all integrated into wheel hub by wheel hub motor, make the mechanical structure portion of automobile significantly
Simplification, but the fever of wheel hub motor and heat dissipation problem constrain wheel hub motor extensive use.Currently for wheel hub motor
Heat dissipation mainly have spray cooling structure（Publication number 206180778U）This device, the device do not account for braking energy
It recycles, this radiating mode needs to consume a large amount of electric energy, and this radiating mode has the course continuation mileage of electric vehicle
Very big restriction, on the other hand, this radiating mode easily leads to electric motor short circuit, seriously affects the safety of row electric vehicle
Property.Also a kind of wheel hub motor radiating mode is to store cooling gas by Brake energy recovery and carried out in due course to wheel hub motor
Heat dissipation（Publication number 204161085U）, the problem of this device considers Brake energy recovery, but and brake energy recovering system
It disagrees, does not account for by inverter storing braking energy in the battery, whole braking energies are cold for recycling storage
But gas, braking energy utilization rate is very low, while the cooling-down effect of the radiating mode is poor.
Invention content
In order to solve the heat dissipation problem of above-mentioned wheel hub motor, the utility model is described based on brake energy recovering system
A kind of novel hub motor radiating controller.
A kind of novel hub motor radiating controller includes mainly SOC estimators, brake pedal sensor, temperature sensing

Bridge, SOC estimators, brake pedal sensor, temperature sensor monitor present battery SOC value, brake pedal status, wheel hub in real time
Motor temperature, controller chip are judged by collecting the output state of each sensor, determine whether must to wheel hub motor into
Row heat dissipation, if desired radiates, and controller chip controls water pump driving circuit and drives pump working, and circulating water flow is formed in pipeline
Realize wheel hub motor heat sinking function.
Use said program, the advantageous effect that the utility model obtains be realize the heat sinking function of wheel hub motor, and
And the heat dissipation that irretrievable braking energy carries out wheel hub motor can be effectively utilized in conjunction with brake energy recovering system, it reduces
The energy expenditure of electric vehicle, effectively raises the course continuation mileage of electric vehicle.

Specific implementation mode
The following describes the utility model in further detail with reference to the accompanying drawings：
A kind of structural schematic diagram of novel hub motor radiating controller, as shown in Figure 1.Include mainly SOC estimators, system
Dynamic pedal sensor, temperature sensor, controller chip, water pump driving circuit, water pump, water tank, pipeline, wheel, wheel hub motor,
The output that axle, battery, relay A, relay B, relay C, IGBT bridge, wherein controller chip pass through each sensor of collection
Whether state is judged radiates braking energy for wheel hub motor.
It is normally off that the original state of each relay, which is relay A, in Fig. 1, and relay B is normally open, relay C
For normally open.
Specific logic control block diagram is as shown in Fig. 2, specific logic is to first determine whether wheel hub motor temperature value is higher than
70 DEG C of setting value, if being higher than setting value, relay C is closed, and battery power water pump makes coolant liquid recycle, and then brake pedal senses
Device judges brake pedal status（）If being in on-position, relay A is closed, and braking energy is rectified into direct current by IGBT bridges
Electricity and the common feed pump drive circuitry of battery, driving water pump make coolant liquid accelerated service, radiate to wheel hub motor,
Under on-position, according to the judgement of SOC estimators, as long as SOC value is higher than 0.9, relay A is disconnected, and relay B is closed, IGBT
