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 parking electric automobile control with failure backup functionality
System processed, after driver 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：It is a kind of that there is the electronic of failure backup functionality
Automobile parking control system, the EPB actuators including P gear parkings ECU, electronic parking ECU and for clamp to be controlled to act, also
Equipped with EPB failure backups ECU, the EPB failure backup ECU are integrated in an integrated form controller with ABS/ESC main control chips
On；EPB actuators can be controlled by the electronic parking ECU and EPB failures backup ECU and electronic parking ECU holds EPB
The priority of row device control is more than EPB failures backup ECU, the EPB fail backup ECU only report an error in electronic parking ECU or
Person's no signal is sent out, and has P gear parking actions to perform in driver, and wheel speed signal is not zero Shi Caihui to the progress of EPB actuators
Control, makes automobile brake.
Preferably, described electronic parking ECU, P gear parking ECU, EPB failure backup ECU and ABS/ESC main control chips and
CAN bus communicates, and the P gear parking action signals of wheel speed signal and P gear parking ECU acquisitions are uploaded to CAN bus.
The present invention is provided with EPB failure backup ECU using above-mentioned technical proposal, and by EPB fail backup ECU and
ABS/ESC main control chips are integrated on an integrated form controller, EPB failures backup ECU only report an error in electronic parking ECU or
No signal is sent out, and has P gear parking actions to perform in driver, and the wheel speed signal Shi Caihui that is not zero controls EPB actuators
System, makes automobile brake.
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 principle of the present invention figure.
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 parking electric automobile control system with failure backup functionality, including P gears parking ECU,
Electronic parking ECU and the EPB actuators for clamp to be controlled to act are additionally provided with EPB failure backups ECU, the EPB failures
Backup ECU is integrated in ABS/ESC main control chips on an integrated form controller；Electronic parking ECU, P gear parking ECU, EPB failure
Backup ECU and ABS/ESC main control chip communicates with CAN bus, and the P gears of wheel speed signal and P gear parking ECU acquisitions are stayed
Vehicle action signal is uploaded to CAN bus, therefore EPB failure backups ECU can obtain wheel speed signal, P gear parkings by CAN bus
Signal and electronic parking ECU report an error or no signal information.
EPB actuators can be controlled by the electronic parking ECU and EPB failures backup ECU and ECU pairs of electronic parking
The priority of EPB actuators control is more than EPB failure backups ECU, and the EPB failure backups ECU is only in electronic parking ECU reports
Wrong or no signal is sent out, and has P gear parking actions to perform in driver, and wheel speed signal is not zero Shi Caihui to EPB actuators
It is controlled, makes automobile brake.
The present invention devises the EPB with failure backup functionality and fails backup ECU, which ensure that when EPB (electronic parking)
When ECU fails, EPB failure backups ECU can still carry out EPB (electronic parking) actuator parking action and perform, and meet P gears and stay
Vehicle demand, make electric vehicle P gear parking have practical significance, so as to improve P gear parking reliability and safety, reduce because
Parking 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 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.
