Specific embodiment
The exemplary embodiment that the present invention will be described in more detail below with reference to accompanying drawings.Although showing the present invention in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the present invention without should be by embodiments set forth here
It is limited.It is to be able to thoroughly understand the present invention on the contrary, providing these embodiments, and can be by the scope of the present invention
It is fully disclosed to those skilled in the art.
Embodiment one
As shown in Figure 1, being specifically included following the embodiment provides a kind of electric car power-on and power-off control method
Step:
Step 101: after detecting that vehicle diagnosis interface is connect with diagnostic device, obtaining the lower electricity that diagnostic device is sent and ask
It asks.
Generally, vehicle diagnosis interface is OBD (On-Board Diagnostic) interface, with automobile electrically-controlled technology
It continues to develop and universal, the effect that OBD fault diagnosis plays is increasing.Such as: when trouble light is prominent in the process of moving for vehicle
It so lights, illustrates the vehicle electrically controlling system there may be failure, need to be overhauled in time.It is connected using dedicated diagnosis computer
The OBD diagnosis information such as interface read failure code and data flow on vehicle just can be carried out Analysis on Fault Diagnosis.It is examined in addition, OBD is vehicle-mounted
Disconnected system also has the function of identification, and there may be the regions of failure, and in a manner of fault code are stored in the information automatically controlled
In cell memory.The failure that can detect components and system using OBD diagnosis interface, guarantees row of the automobile in service life
Put the requirement no more than OBD regulation, and the MIL lamp on operating board is alarmed, to prompt fault car that can obtain and
Shi Xiuli.
Generally, the connection status of vehicle diagnosis interface has the first state connecting with diagnostic device and vehicle diagnosis
The second vacant state of interface.It therefore, before step 101, should also include: full-vehicle control unit (VCU, Vehicle
Control Unit) detection automotive diagnosis port connection status the step of.When vehicle diagnosis interface is in the second vacant state
When, OBD system periodically carries out vehicle self-test, when vehicle diagnosis interface is in the first state connecting with diagnostic device, leads to
It crosses separate diagnostic device and diagnosis detection is carried out to vehicle.
Step 102: being requested according to lower electricity, control vehicle, which is in power-down state and controls diagnostic device, lights lamp for repairing.
After detecting that vehicle diagnosis interface is in the first state connecting with diagnostic device, VCU receives diagnostic device hair
The lower electricity request sent, and requested according to the lower electricity, control vehicle, which is in power-down state and controls diagnostic device, lights lamp for repairing.Tool
Body, to ensure that vehicle is in power-down state, after step 102 is specifically includes the following steps: get lower electricity request, detect vehicle
Whether power-down state is in；If so, directly controlling diagnostic device lights lamp for repairing；If it is not, then controlling vehicle is in lower electric shape
State simultaneously controls diagnostic device and lights lamp for repairing.That is, VCU judges after getting the lower electricity request that diagnostic device issues
The upper and lower electricity condition of vehicle directly lights lamp for repairing if vehicle is in power-down state, can repair work；If
Vehicle is in power-up state, then VCU forces lower electricity, so that vehicle is in power-down state and is controlled lamp for repairing and lights.Specifically repair
The illuminating state of lamp can be long bright, flashing or other are different from the state of OFF state.
Step 103: within the duration that lamp for repairing is in illuminating state, ignoring whole power-up requests.
Indicate that vehicle is in inspecting state within the duration that lamp for repairing is in illuminating state, it is necessary to assure vehicle is in
Therefore power-down state if get power-up request within the duration that lamp for repairing is in illuminating state, directly ignores whole
Power-up request, to avoid the damage caused by instantaneous pressure caused by unexpected power on to vehicle electric-control system.Wherein, it powers on and asks
Asking can be through the triggering generation of remote controllers, timing DCDC circuit or key.
The preferred embodiment of the present invention is described further below in conjunction with Fig. 2.As shown in Fig. 2, the embodiment of the present invention
Electric car power-on and power-off control method specifically includes the following steps:
Step 21: establishing the connection of diagnostic device Yu vehicle diagnosis interface, i.e., automobile is inserted by private communication cable and examined
In slave interrupt interface, to realize the connection between diagnostic device and vehicle diagnosis interface, communication link between the two is established.
Step 22: diagnostic device sends electricity request to the VCU of tested automobile by vehicle diagnosis interface.
After step 23:VCU receives the lower electricity request, whether detection vehicle is in power-down state.
Step 24: if so, the lamp for repairing of control diagnostic device is lighted.
Step 25: if it is not, then forcing lower electricity, and after vehicle is in power-down state, controlling the lamp for repairing point of diagnostic device
It is bright.
Step 26: within the duration that lamp for repairing is in illuminating state, ignoring all power-up requests.
In this way, the electric car power-on and power-off control method of the present embodiment, is detecting automotive diagnosis port and diagnostic device company
After connecing, control vehicle is in power-down state and controls the lamp for repairing for lighting diagnostic device, and the duration lighted in lamp for repairing
Inside ignore all power-up requests, to guarantee that vehicle is in power-down state always in the maintenance period, avoids due to unexpected power on
Caused by instantaneous pressure vehicle ECU circuit is damaged.
