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.
