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.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Electric vehicle in the application specifically can be pure electric vehicle, fuel-cell vehicle or hybrid power fuel cell
Vehicle etc..Pure electric vehicle provides energy by power battery；Fuel-cell vehicle provides energy by fuel cell；Hybrid power combustion
Material fuel cell vehicle provides energy jointly by power battery and fuel cell.
The core ideas of the application is, increases the starting control strategy of air pump in entire car controller, vehicle launch it
Before, control air pump work a period of time, detection air pump whether there is failure, and then reduce in electric vehicle road driving, due to
Accident caused by air pump failure occurs.It is a kind of air pump fault detection side of electric vehicle provided in this embodiment referring to Fig. 1
Method, comprising steps of
S11: after low pressure powers on, whether the state for detecting electric vehicle is parked state, if so, control air pump starts
Work.
Entire car controller is after low pressure powers on, regardless of the air pressure for braking air accumulator, as long as vehicle is in parked state,
Then control air pump work a period of time.
P grades are the gears being evolved on the basis of N grades, other than speed changer to be placed in neutral mode work, are also existed
Transmission internal be equipped with pawl clasp the gear on output shaft to form mechanical locking, thus block drive shaft play fixation it is quiet
Only or the effect of fine motion vehicle.If vehicle is in P grades, then it represents that the vehicle is in parked state.The vehicle of some vehicles is not deposited
At P grades, if the vehicle is in N grades, and uses additional auxiliary brake and carried out parking, it is determined that the vehicle is in parking
State.
It controls air pump to start to work, i.e., vehicle control unit controls electronic switch closure is that air pump is powered, and is given by CAN line
Air pump controller sends enabling signal, and control air pump starts work.
S12: detection air pump whether there is failure, if so, prompting air pump to driver, there are failures.
Step S12 is executed, during air pump work, real-time detection air pump whether there is failure.Event for air pump
Hinder detection method, the application without limitation, as long as being able to achieve the fault detection to air pump.
Prompting air pump to driver, there are the modes of failure, specifically can be through the display or LED light on vehicle,
Air pump malfunction coefficient is carried out, the casting of air pump failure can also be carried out by the audio playing apparatus on vehicle.
S13: judging whether the continuous working period of air pump is greater than preset first time threshold, if so, control air pump
It stops working.
The setting of first time threshold can maximum duration required for the fault detection according to air pump.Air pump fault type
Including but not limited to under-voltage fault, over-voltage fault, overheating fault, short trouble, overload fault, open-phase fault and communicating terminal etc.
Deng.For different types of air pump fault detection, the required time may be different；It first determines in this application different types of
Then required maximum duration in air pump fault detection is arranged first time threshold and is greater than the maximum duration.Execute step
S13 just controls air pump and stops working after air pump continuous working period is greater than first time threshold.
Control air pump stops working, i.e., entire car controller sends stop signal to air pump controller by CAN line, controls gas
Pump stops working, and controls electronic switch and open and stop being that air pump is powered.
The air pump fault detection method of electric vehicle provided in this embodiment is powered in electric vehicle low pressure also in parking
When state, regardless of the air pressure for braking air accumulator, control air pump is started to work, and in the air pump course of work to air pump into
Row fault detection, and then before electric vehicle starting, just detecting air pump whether there is failure, reduce electric vehicle road driving
In, the accident as caused by air pump failure occurs.
When braking air accumulator includes electronic type pressure release valve type, in order to avoid the pressure in braking air accumulator is excessive, referring to figure
2, after controlling the step of air pump is started to work, can also include:
S14: whether the air pressure of detection braking air accumulator is greater than preset first air pressure threshold value, if so, control braking storage
The electronic type relief valve of gas tank is opened.
Step S14 is executed, during air pump work, whether the air pressure of real-time detection braking air accumulator is greater than the first gas
Press threshold value.First air pressure threshold value be avoid braking air accumulator in air pressure it is excessive and be arranged an air pressure threshold value, braking gas storage
When air pressure in tank is greater than the air pressure threshold value, with regard to being deflated by electronic type relief valve to braking air accumulator.Entire car controller
After controlling the unlatching of electronic type relief valve, the gas braked in air accumulator starts to be discharged, and thereby reduces the gas in braking air accumulator
Pressure.
It should be noted that being front axle brake gas storage respectively there are two the braking air accumulators of the electric vehicle of some vehicles
Tank and rear axle brake air accumulator；Air pressure energy is provided for the front axle brake of vehicle by front axle brake air accumulator, by rear axle system
Dynamic air accumulator provides air pressure energy for the rear axle braking of vehicle.It can be inflated by air pump while to front axle brake air accumulator with after
Axis braking air accumulator is inflated.
S15: after the duration that relief valve is opened is greater than preset second time threshold, control electronic type relief valve is closed
It closes.
The setting of second time threshold can guarantee that air pump continues to work until first time threshold, and braking will not be caused to store up
Air pressure in gas tank is greater than the first air pressure threshold value.
It is shown in Figure 3, pressure release can also be controlled after the continuous working period for judging air pump is greater than first time threshold
Valve is closed.
In order to proper moment to air pump carry out fault detection, can also detection vehicle-state whether the step of parked state
Before rapid, judge that current low pressure powers on and the time under a preceding low pressure between electricity, if it is greater than preset third time threshold,
If so, execute again detection vehicle-state whether parked state the step of, if it is not, subsequent judgement is then no longer executed, such as Fig. 4 institute
Show.Specifically, third time threshold can be set to 1 day.
For the various method embodiments described above, for simple description, therefore, it is stated as a series of action combinations, but
Be those skilled in the art should understand that, the present invention is not limited by the sequence of acts described because according to the present invention, certain
A little steps can be performed in other orders or simultaneously.Illustratively, whether the air pressure of detection braking air accumulator is greater than default
The first air pressure threshold value, and detection air pump whether there is failure, can carry out simultaneously.
