Central gateway (Center Gateway, CGW) 210 couple.
Fig. 2 show the control system of the power battery pack for replacing vehicle automatically according to one embodiment of the invention
Modular structure schematic diagram.The control system 20 is at least partly run in full-vehicle control unit VCU220, to realize in vehicle
The cooperation of 900 sides is completed to move electric process certainly.It will be understood that in other alternative embodiments, control system 20 can also at least portion
It runs on dividing in other processors or microcontroller with calculation processing function of vehicle 900 and realizes, alternatively to realize
The function in terms of the power battery pack of replacement vehicle automatically of the VCU 200 of following example.
It should be noted that being configured with vehicle body CAN network in vehicle 900, each electronic component in vehicle 900 is connected
Or electronic module is to realize communicating with one another between them.The electronic component arranged in vehicle body CAN network includes but is not limited to CGW
210 and VCU220, such as, further includes: IBS(intelligent battery sensor), screen is controlled in CDC(), BCM(car body control module), BMS
(battery management system), electric machine controller etc.；Their specific arrangement method is not limiting.
As shown in Fig. 2, control system 20 includes the VCU220 being arranged in vehicle 900, wherein in changing electric process,
VCU220 can be interacted by the electric coupling of main control unit 110 row information of going forward side by side of changing of CGW 210 and electrical changing station 10.
In conjunction with shown in Fig. 2 and Fig. 3, in one embodiment, VCU220 include the first control module 221, be used in response to
First control signal is generated into the instruction for changing the electric stage, first control signal is used at least forbid (Disable) vehicle 900
High pressure wake source changes electric ready mode 320 to help vehicle 900 to enter from normal mode 310.Wherein, into the finger for changing the electric stage
Order, which can be to come from, changes electric main control unit 110, such as electric master control is changed behind the predetermined position that vehicle 900 is adjusted at electrical changing station 10
Unit 110 is transmitted into the instruction for changing the electric stage to CGW 210, and (forwarding can be with difference by CAN network forwarding by CGW 210
Signal form is sent) to VCU220.Wherein, high pressure wake source, which refers to, actively can wake up or trigger the device for carrying out high voltage supply
Or component, for example, may include the arousal function of IBS, remote high-voltage power-up request (such as remotely starting vehicle when) and/or

It will be understood that the first control signal of generation can be sent to the corresponding electronics in the vehicle body CAN network of vehicle 900
Component or electronic module, to realize the high pressure wake source function of for example forbidding vehicle 900.
It will be understood that high pressure wake source is normal work under normal mode 310, and it is high in the case where changing electric ready mode 320
It is forbidden for pressing wake source；Normal mode 310 and the difference changed between electric ready mode 320 are not limited in high pressure wake source
The difference of aspect, with normal mode 310 and change electric ready mode 320 to be specifically defined condition related, such as, if forbid slope
Row torque etc..
In one embodiment, first control signal is also used to forbid the slope row torque of vehicle 900 to export to help vehicle 900
Enter from normal mode 310 and change electric ready mode 320, in this way, preventing vehicle 900 from actively shifting in changing electric process.In the reality
It applies in example, the slope row torque output of the vehicle 900 changed under electric ready mode 320 is prohibited.
In one embodiment, VCU220 further includes the second control module 222, and the second control module 222 is for generating second
Control signal, wherein second control signal is used to that vehicle 900 is made to realize that electricity is under high pressure to help vehicle 900 to prepare mould from electricity is changed
Formula 320 enters safe mode 330.Wherein, specifically it can pass through diagnostic service (such as base in response to changing electric main control unit 110
In the diagnostic service of diagnostic service agreement) under the high pressure that sends electric diagnostic instruction generate second control signal.
It will be understood that the second control signal of generation can be sent to the corresponding electronics in the vehicle body CAN network of vehicle 900
Component or electronic module, to realize electricity under such as high pressure of vehicle 900.Illustratively, VCU220 receives diagnosis electric under high pressure and refers to
After order, the instruction of lower high pressure can be sent by the CAN bus of dynamical system, and the priority of the instruction is highest, BMS
