Description
Technical field
The present invention relates to electric vehicles, and in particular to parking electric automobile system.
Background technology
It is to rely on the difference of the mechanical locking arrangement realization in gearbox to keep off parking with P in conventional internal combustion vehicle, most electronic
The gearbox of vehicle eliminates P gear mechanical locking arrangements, but the gear of P gear parkings is still remained in electric vehicle, electric vehicle P gears
Parking function is actually what is performed by EPB, once EPB controllers break down, vehicle will be unable to realize parking function so that
The setting of electric vehicle P gear gears loses meaning, and may cause traffic accident, jeopardizes the safety of driver and passenger.
Invention content
The technical problems to be solved by the invention are just to provide a kind of EPB control systems of band failure backup functionality, are driving
After the person of sailing sends out P gear parking instructions, i.e. electronic parking ECU fails, and can also realize the parking function of vehicle.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of EPB controls of band failure backup functionality
System, the EPB actuators including electronic parking ECU and for clamp to be controlled to act further include P gear parking ECU, the electronics
Parking ECU is integrated on an integrated form ECU with EPB failure fallback circuits, the EPB failure fallback circuits and electric vehicle
On arbitrary control unit ECU in addition to electronic parking ECU connected by communication line, via removing electronic parking on electric vehicle
The EPB failure fallback circuits of arbitrary control unit ECU controls outside ECU can carry out EPB actuators action execution, and only
It reports an error in electronic parking ECU or no signal is sent out, while there are P gear parking actions to perform in driver, wheel speed signal is not zero
Shi Caihui controls EPB actuators, makes automobile brake.
Preferably, described electronic parking ECU, P keep off arbitrary in addition to electronic parking ECU on parking ECU and electric vehicle
Control unit ECU communicates with CAN bus, and the P gear parking action signals of wheel speed signal and P gear parking ECU acquisitions upload
To CAN bus.
The present invention is provided with one by the arbitrary control on electric vehicle in addition to electronic parking ECU using above-mentioned technical proposal
The EPB failure fallback circuits of unit ECU controls, EPB failures fallback circuit only reports an error in electronic parking ECU or no signal is sent out
Go out, and there are P gear parking actions to perform in driver, the wheel speed signal Shi Caihui that is not zero controls EPB actuators, makes automobile
Braking.
Therefore, the present invention has the advantages that：Make P gear parkings that there is practical function, realize P gear parkings and parking brake
The dual parking of (electronic parking) ensures.The achieved reliability of parking is improved, improves the safety of vehicle parking.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and detailed description：
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Below
Description only actually at least one exemplary embodiment is illustrative, is never used as to the present invention and its application or makes
Any restrictions.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of EPB control systems of band failure backup functionality, including P gear parkings ECU, electronic parking ECU
And the EPB actuators for clamp to be controlled to act, wherein, the electronic parking ECU, which is integrated in one, has EPB failure backup electricity
On the integrated form ECU on road, the EPB failure fallback circuits and the arbitrary control unit on electric vehicle in addition to electronic parking ECU
ECU is connected by communication line；Described electronic parking ECU, P are kept off on parking ECU and electric vehicle in addition to electronic parking ECU
Arbitrary control unit ECU communicates with CAN bus, reports an error in electronic parking ECU or no signal sends out information, wheel speed letter
Number and the P gear parking action signals of P gear parking ECU acquisitions be uploaded to CAN bus, on electric vehicle in addition to electronic parking ECU
Arbitrary control unit ECU electronic parking ECU obtained by bus report an error or no signal sends out information, wheel speed signal and P
The P gear parking action signals of parking ECU acquisitions are kept off, and EPB failure fallback circuits are controlled according to these information.
EPB actuators can be controlled for the electronic parking ECU and EPB failure fallback circuits and electronic parking ECU
It is more than EPB failures fallback circuit/EPB failure backups ECU, the EPB failures fallback circuit to the priority of EPB actuators control
It only reports an error in electronic parking ECU or no signal is sent out, and there are P gear parking actions to perform in driver, wheel speed signal is not
EPB actuators can just be controlled when zero, make automobile brake.
The present invention devises the EPB failure fallback circuits with failure backup functionality, ensure that as EPB (electronic parking) ECU
During failure, EPB failures fallback circuit can still carry out EPB (electronic parking) actuator parking action and perform, and meet P gear parkings
Demand makes electric vehicle P gear parkings have practical significance, so as to improve the reliability of P gear parkings and safety, reduces because staying
Vehicle failure causes the risk of traffic accident.
Certainly, it will be appreciated by persons skilled in the art that other communication bus connection in addition to CAN can also be used
It communicates.
In the present embodiment, the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU uses ABS unit ECU
Or ESC units ECU.It is sent from ABS unit ECU or ESC unit ECU to EPB failure fallback circuits and performs signal, so as to make
EPB failure fallback circuits carry out EPB actuators control and realize electric vehicle brake.
In addition to above preferred embodiment, the present invention also has other embodiments, and those skilled in the art can be according to this
Invention makes various changes and modifications, and without departing from the spirit of the present invention, should all belong in claims of the present invention and determine
The range of justice.
