Abstract
The invention discloses a kind of parking electric automobile control systems, EPB actuators including electronic parking ECU and for clamp to be controlled to act, further include P gear parking ECU and EPB backup execution circuits, the EPB backups execution circuit is connect with the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU by communication line, and it is controlled by the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU, arbitrary control unit ECU on the electric vehicle in addition to electronic parking 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 electronic parking 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 electric automobile control system, are sent out in driver
After 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 electric automobile control system, packet
Electronic parking ECU and the EPB actuators for clamp to be controlled to act are included, P gear parking ECU and EPB backups is further included and performs
Circuit, the EPB backups execution circuit passes through with the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU to communicate
Connection, and controlled by the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU, the electronic parking
ECU can control, and electronics EPB actuators with the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU
Parking ECU is more than the priority that EPB actuators control the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU,
Arbitrary control unit ECU on the electric vehicle in addition to electronic parking ECU only reports an error or no signal in electronic parking ECU
It sends out, and has in driver that P gear parking actions perform, the wheel speed signal Shi Caihui that is not zero controls EPB actuators, make electricity
Electrical automobile is braked.
Preferably, the electronic parking ECU, the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU and
P gears parking ECU communicates with CAN bus, and wheel speed signal and P gear parking action signals are uploaded to CAN bus.
Preferably, the arbitrary control unit ECU on the electric vehicle in addition to electronic parking ECU include ABS unit ECU,
ESC units ECU.
Invention increases EPB backup execution circuits, and pass through the arbitrary control on electric vehicle in addition to electronic parking ECU
Unit ECU sends control signal and gives EPB backup execution circuits, and EPB backups execution circuit is made to report an error or nothing in electronic parking ECU
Signal is sent out, and has in driver that P gear parking actions perform, the wheel speed signal Shi Caihui that is not zero controls EPB actuators,
Make electric vehicle 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, 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 electric automobile control system, including P gear parkings ECU, electronic parking ECU, EPB backup
Execution circuit and the EPB actuators for clamp to be controlled to act, the electronic parking ECU and EPB backup execution circuits
EPB actuators are controlled, and electronic parking ECU is more than EPB backup execution circuits to the priority that EPB actuators control,
The EPB backups execution circuit is connected with the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU by communication line
It connects, and is controlled by the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU, the EPB backups execution circuit
Only report an error in electronic parking ECU or no signal sent out, and driver have P gear parking action perform, wheel speed signal be not
EPB actuators can just be controlled when zero, make electric vehicle brake.Parking is kept off so as to fulfill P and electronic parking is dual to vehicle
Parking braking, in the case where a side is failed, another part, which remains unchanged, can realize the parking function of vehicle, improve parking
Achieved reliability, improve the safety of vehicle parking.
Wherein, the electronic parking ECU, the arbitrary control unit ECU and P on electric vehicle in addition to electronic parking ECU
Gear parking ECU communicates with CAN bus.The wheel speed signal and P gear parking action signals of wheel speed sensors acquisition can upload
To CAN bus, the arbitrary control unit ECU on electric vehicle in addition to electronic parking ECU can also obtain wheel speed by CAN bus
Signal, P gear parking action signals and electronic parking ECU error signals (or no signal).Certainly, those skilled in the art can
With understanding, other communication bus connection in addition to CAN can also be used to communicate.
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 backups execution circuit and performs signal, so as to make
EPB backups execution circuit carries out EPB actuators control and realizes 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
