Specific embodiment
Exemplary embodiment of the invention is more fully described below with reference to accompanying drawings.Although showing the present invention in accompanying 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
Limited.Conversely, there is provided these embodiments are able to be best understood from the present invention, and can be by the scope of the present invention
Complete conveys to those skilled in the art.
Embodiment one
As shown in figure 1, The embodiment provides a kind of electric automobile power-on and power-off control method, specifically including following
Step:
Step 101:Detecting after vehicle diagnosis interface is connected with diagnostic device, obtaining lower electricity that diagnostic device sends please
Ask.
Usually, vehicle diagnosis interface is OBD (On-Board Diagnostic) interface, with automobile electrically-controlled technology
Continue to develop with popularization, OBD fault diagnosises play effect it is increasing.For example:When vehicle, trouble light is dashed forward in the process of moving
So light, illustrate that the vehicle electrically controlling system there may be failure, it is necessary to be overhauled in time.Connected using special diagnosis computer
The information such as OBD diagnosis interface read failure codes and data flow on car can just carry out Analysis on Fault Diagnosis.Additionally, OBD is vehicle-mounted examining
Also there is disconnected system identification there may be the function in the region of failure, and be stored in the information in the way of failure code automatically controlled
In cell memory.Using the detectable parts of OBD diagnosis interfaces and the failure of system, it is ensured that row of the automobile in service life
Put the requirement no more than OBD regulations, and MIL lamps on operating board are alarmed, pointing out fault car to obtain and
Shi Xiuli.
Usually, the connection status of vehicle diagnosis interface has the first state being connected with diagnostic device, and vehicle diagnosis
The second vacant state of interface.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-inspection, when vehicle diagnosis interface is in the first state being connected with diagnostic device, leads to
Cross separate diagnostic device carries out diagnosis detection to vehicle.
Step 102:According to lower electricity request, control vehicle is in power-down state and controls diagnostic device to light lamp for repairing.
After first state of the vehicle diagnosis interface in being connected with diagnostic device is detected, VCU receives diagnostic device hair
The lower electricity request sent, and according to the lower electricity request, control vehicle is in power-down state and controls diagnostic device to light lamp for repairing.Tool
Body ground, to ensure that vehicle is in power-down state, step 102 specifically includes following steps:After getting lower electricity request, vehicle is detected
Whether power-down state is in;If so, then directly control diagnostic device lights lamp for repairing;If it is not, then control vehicle is in lower electric shape
State simultaneously controls diagnostic device to light lamp for repairing.That is, VCU judges after the lower electricity request that diagnostic device is issued is got
The upper and lower electricity condition of vehicle, if vehicle is in power-down state, directly lights lamp for repairing, can carry out maintenance work;If
Vehicle is in power-up state, then VCU forces lower electricity, vehicle is in power-down state and controls lamp for repairing to light.Specifically repair
The illuminating state of lamp can grow bright, flicker or other are different from the state of OFF state.
Step 103:It is in the duration of illuminating state in lamp for repairing, ignores whole power-up requests.
Represent that vehicle is in inspecting state in lamp for repairing is in the duration of illuminating state, it is necessary to assure vehicle is in
Power-down state, therefore, if get power-up request in lamp for repairing is in the duration of illuminating state, directly ignore whole
Power-up request, with the damage to vehicle electric-control system that the instantaneous pressure for avoiding unexpected upper electricity from causing is caused.Wherein, upper electricity please
Asking can trigger to generate by remote controllers, timing DCDC circuits or key.
The preferred embodiments of the present invention are described further below in conjunction with Fig. 2.As shown in Fig. 2 the embodiment of the present invention
The power-on and power-off control method of electric automobile specifically include following steps:
Step 21:The connection of diagnostic device and vehicle diagnosis interface is set up, 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 set up.
Step 22:Diagnostic device sends electricity request by vehicle diagnosis interface to the VCU of tested automobile.
Step 23:After VCU receives the lower electricity request, whether detection vehicle is in power-down state.
Step 24:If so, then 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, control the lamp for repairing point of diagnostic device
It is bright.
Step 26:It is in the duration of illuminating state in lamp for repairing, ignores all of power-up request.
So, the electric automobile power-on and power-off control method of the present embodiment, connects automotive diagnosis port is detected with diagnostic device
After connecing, control vehicle is in power-down state and controls to light the lamp for repairing of diagnostic device, and the duration lighted in lamp for repairing
Inside ignore all power-up requests, to ensure to be in power-down state all the time in maintenance period vehicle, it is to avoid because of unexpected upper electricity
The instantaneous pressure for causing causes to damage to vehicle ECU circuits.
