Description
Technical field
The invention belongs to field of automobile electronic control.
Background technology
At present, as energetically promotion of the country to new-energy automobile, electric automobile gradually come into our life, its
Middle wheel hub motor is gradually applied to electric automobile with the advantages that its structure arrangement is simple, power density is high, turns into electric automobile weight
The part wanted.Power, transmission and brake apparatus are all incorporated into wheel hub, although the mechanical structure portion of automobile is greatly
Simplify, but restrict an important factor for heating of wheel hub motor and heat dissipation problem are wheel hub motor extensive uses.Currently for
The radiating of wheel hub motor mainly has spray cooling structure（Publication number 206180778U）This device, does not account for braking energy
The problem of utilization, this radiating mode need substantial amounts of electric energy to be driven, substantial amounts of energy are consumed, for pure electric automobile
For, optimization always its key issue considered of the consumption of energy, continuation of the journey of this radiating mode to electric automobile
Mileage has very big restriction, and on the other hand, this radiating mode is spray cooling, easily causes motor breaking, serious shadow
Ring the security of driving.Also a kind of wheel hub motor radiating mode is simultaneously in good time right by Brake energy recovery storage cooling gas
Wheel hub motor is radiated（Publication number 204161085U）, the problem of this device considers Brake energy recovery, but with braking
Energy-recuperation system is disagreed, and does not account for by inverter storing braking energy in the battery, whole braking energies are used
Cooling gas is stored in recovery, braking energy utilization rate is very low.
The content of the invention
In order to solve the heat dissipation problem of above-mentioned wheel hub motor, invention describes one kind based on brake energy recovering system
Novel hub motor radiating controller.
A kind of novel hub motor radiating controller mainly includes SOC estimators, brake pedal sensor, TEMP
Device, controller chip, water pump drive circuit, water pump, water tank, pipeline, wheel, wheel hub motor, axletree, battery, relay, IGBT
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 that wheel hub motor must be entered
Row radiating, if desired radiates, and controller chip control water pump drive circuit driving pump working, circulating water flow is formed in pipeline
Realize wheel hub motor heat sinking function.
Such scheme is employed, the beneficial effect that the present invention obtains is to realize the heat sinking function of wheel hub motor, and is tied
The radiating that irretrievable braking energy carries out wheel hub motor can be effectively utilized by closing brake energy recovering system, reduce electricity
The energy expenditure of electrical automobile, effectively raise the course continuation mileage of electric automobile.
Brief description of the drawings

Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings：
A kind of structural representation of novel hub motor radiating controller, as shown in Figure 1.Mainly include SOC estimators, braking is stepped on
Plate sensor, temperature sensor, controller chip, water pump drive circuit, water pump, water tank, pipeline, wheel, wheel hub motor, car
Axle, battery, relay A, relay B, relay C, IGBT bridge, wherein controller chip are by collecting the output shape of each sensor
Whether state judges radiates braking energy for wheel hub motor.
The original state of each relay is that relay A is normally off 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 closures, battery power water pump circulates coolant, and then brake pedal senses
Device judges brake pedal status, if being in on-position, relay A closures, braking energy is rectified into direct current by IGBT bridges
With the common feed pump drive circuitry of battery, driving water pump makes coolant accelerated service, wheel hub motor is radiated, made
Under dynamic state, according to the judgement of SOC estimators, as long as SOC value is higher than 0.9, relay A disconnects, relay B closures, IGBT bridges
Braking energy is rectified into direct current whole feed pump drive circuitry, driving water pump makes coolant accelerated service, to wheel hub
Motor is radiated.
