Below with reference to the accompanying drawings the control method of finished and dynamical system of the hybrid vehicle of the embodiment of the present invention are described.
Fig. 1 is the flow chart of the control method of finished of hybrid vehicle according to an embodiment of the invention.
In general, the entire car controller in hybrid vehicle is the core component of hybrid electric vehicle complete vehicle control system. In order to which those skilled in the art more understand specific control process of the entire car controller as core component, have with reference to Fig. 2 and Fig. 3 Body is described as follows：
Fig. 2 is the schematic diagram of vehicle control unit controls according to an embodiment of the invention.As shown in Fig. 2, full-vehicle control Device can acquire the signal of accelerator pedal input, the signal that brake pedal inputs and other component signal.Entire car controller is simultaneously After corresponding judgement can be made according to above-mentioned signal, passes through CAN network bus marco BMS, ENG, ECM and BCM etc. and carry out phase It should operate, and realize and the network information is managed, dispatch, analyze and is calculated.
More specifically, Fig. 3 is the signal of operating mode when VCU is normal in the prior art according to an embodiment of the present invention Figure.As shown in Figure 3：
After step 1, BCM detect that driver has start-up operation, i.e. BCM to detect the enabling signal of hybrid vehicle, Solicited message will be started and be sent respectively to VCU, ENG and ECM.
After step 2, VCU receive startup solicited message, self-test order is sent to TCU, BMS and auxiliary-motor controller respectively.
After step 3, TCU, BMS and auxiliary-motor controller carry out self-test according to self-test order, self-detection result information is sent To VCU.
When step 4, VCU can meet entry condition according to above-mentioned self-detection result, can to ENG send out start request and to ECM hairs start request.
After step 5, the startup for receiving BCM transmissions in ENG are asked, ENG and ECM are to code.
Step 6, when ENG and ECM is to code success, ENG and ECM " starting allows " will issue VCU respectively.
Step 7, VCU issue BCM by order is started.
It can more have a clear understanding of how VCU realizes full-vehicle control by foregoing description as a result, control hybrid vehicle Start.
In addition, VCU can be directed to the different configurations of vehicle, carry out corresponding energy management, realize vehicle drive control, Energy optimal control, feedback braking control and network management control.When entire car controller fails, by turning off generator and cutting Disconnected busbar high-pressure system, forbids hybrid vehicle to power on, so that hybrid vehicle can not travel.
It is understood that a critical function of whole car controller of hybrid electric car is exactly model selection and torque point Match, once entire car controller fails, vehicle can not carry out effective model selection and torque distribution, and engine and motor can not be again Normally driven.
Therefore, it is directly hybrid vehicle to be forbidden to power on, and turn off generator and cut-out mother according to above-mentioned processing mode Line high-pressure system.Hybrid vehicle can only be parked in original place and wait for rescue, it is impossible to ensure that vehicle security.
In order to avoid the above problem, the present invention proposes a kind of control method of finished of hybrid vehicle, can be lost in VCU When effect, it still is able to so that vehicle travels, control hybrid vehicle is walked lamely to target location safely, ensure that vehicle security. It is specific as follows：
As shown in Figure 1, the control method of finished of the hybrid vehicle includes the following steps：
Step 101, after car body control module BCM detects the enabling signal of hybrid vehicle, respectively to full-vehicle control Device VCU, motor control module ENG and engine control module ECM, which are sent, starts solicited message.
It should be understood that driver can start vehicle by the modes such as ON keys on car key, pressing vehicle. After driver starts vehicle by any of the above-described kind of mode, BCM is able to detect that the start-up operation of driver, and respectively to VCU, ENG and ECM, which is sent, starts request.
It should be noted that no matter when VCU is normal in operating mode, or when VCU fails in operating mode, BCM It detects that driver has start-up operation, is all sent respectively to VCU, ENG and ECM and start request.
Step 102, when a inside in BCM, ENG and ECM is provided with backup module, if backup module is in preset time The feedback information that VCU is generated based on startup solicited message is not received inside, then respectively to Transmission Control Module TCU, battery Management module BMS and auxiliary-motor controller send self-test order.
Specifically, can select according to the actual application in BCM, ENG and ECM one can the inside be provided with and have The module of backup functionality, i.e. backup module.
It should be noted that after when VCU is normal, BCM sends and starts request under operating mode, feedback that VCU will be generated Information is sent to BCM, ENG and ECM simultaneously.
Specifically, if when backup module do not received in preset time VCU based on start solicited message generated it is anti- Feedforward information (i.e. VCU failures) needs to send out to Transmission Control Module TCU, battery management module BMS and auxiliary-motor controller respectively Send self-test order.
Wherein, preset time can carry out selection setting according to the actual application.Generally, preset time be VCU just After BCM sends startup request under operating mode when normal, VCU is responded and can be sent to the longest permission of ECM and ENG feedback informations Time interval.
As an example, when VCU fails, ECM enables full-vehicle control miscellaneous function as backup module temporarily, integrates Modules.Fig. 4 is the schematic diagram of ECM controls after VCU failures according to an embodiment of the invention.
As shown in figure 4, ECM can acquire the signal of accelerator pedal input, the signal of brake pedal input and other portions Part signal.ECM and can be made according to above-mentioned signal it is corresponding judge after, by CAN network bus marco BMS, ENG, ECM and BCM etc. carries out corresponding operating.
It should be noted that BCM and ENG can also be used as backup module above-mentioned control process in real time.
If it should be noted that backup module receives the feedback information that VCU is generated, backup module in preset time It is stopped.
