Abstract
The invention discloses a kind of parking control systems for electric vehicle, including P gear parkings ECU, electronic parking ECU, EPB backups ECU and the EPB actuators for clamp to be controlled to act, the electronic parking ECU and EPB backups ECU can control EPB actuators, and electronic parking ECU is more than EPB backups ECU to the priority that EPB actuators control, the EPB backups ECU 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, the wheel speed signal Shi Caihui that is not zero controls EPB actuators, make electric vehicle brake.The present invention makes P gear parkings have practical function, realizes P gear parkings and the dual parking of parking brake ensures, so as to improve the reliability of P gear parkings and safety, reduces to fail because of parking and causes the risk of traffic accident.
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 control system for electric vehicle, are driving
After member 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 parking for electric vehicle controls
System, the EPB actuators including P gear parkings ECU, electronic parking ECU, EPB backup ECU and for clamp to be controlled to act, institute
Can EPB actuators be controlled by stating electronic parking ECU and EPB backups ECU, and electronic parking ECU controls EPB actuators
Priority be more than EPB backups ECU, the EPB backups ECU only reports an error in electronic parking ECU or no signal is sent out, and
Driver has P gear parking actions to perform, wheel speed signal is not zero, and Shi Caihui controls EPB actuators, makes electric vehicle system
It is dynamic.
Preferably, electronic parking ECU, EPB backup ECU and P gear the parking ECU communicates with CAN bus, electronics
Parking ECU reports an error or no signal sends out information, wheel speed signal and P gear parking action signals and is uploaded to CAN bus.
It reports an error invention increases EPB backups ECU, EPB backup ECU in electronic parking ECU or no signal is sent out, and
Driver has P gear parking actions to perform, wheel speed signal is not zero, and Shi Caihui controls EPB actuators, makes electric vehicle system
It is dynamic.
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, so as to improve the reliability of P gear parkings and safety, reduces because parking failure is drawn
Send out the risk of traffic accident.
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 control system for electric vehicle, including P gear parkings ECU, electronic parking ECU,
EPB backups ECU and the EPB actuators for clamp to be controlled to act, the electronic parking ECU and EPB backups ECU can be right
EPB actuators are controlled, and electronic parking ECU is more than EPB backups ECU, the EPB to the priority that EPB actuators control
Backup ECU only reports an error in electronic parking ECU or no signal is sent out, and has P gear parking actions execution, wheel speed letter in driver
The Shi Caihui that number is not zero controls EPB actuators, makes electric vehicle brake.Parking is kept off so as to fulfill P and electronic parking is double
Again to the parking braking of vehicle, in the case where a side is failed, another part, which remains unchanged, can realize the parking function of vehicle, improve
The achieved reliability of parking, improves the safety of vehicle parking.
Wherein, electronic parking ECU, EPB backups ECU and P gear parking ECU communicate with CAN bus, wheel speed signal with
And the P gear parking action signals that P gears parking ECU is sent out are uploaded to CAN bus.In this way, electronic parking ECU reports an error or no signal
Send out information, wheel speed signal and P gear parking action signal be uploaded to CAN bus after, EPB backups ECU by with CAN bus
Communication, which obtains P gear parking actions and performs signal, wheel speed signal, to be not zero signal and electronic parking ECU reports an error or no signal is sent out
Information.
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.
Due to directly being controlled by EPB backups ECU EPB actuators, control structure is simplified the present invention.
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.
