Description
Technical field
It is particularly a kind of based on the management of electric automobile high-voltage system electrification the present invention relates to a kind of Vehicle Electronic Control method
Control method.
Background technology
With the intensification of the energy and environmental issue, " energy-saving, environmental protection " has become the two of current social development
Big theme, and electric motor car recoverable amount continue to increase and various high-voltage safety accidents appearance so that electric automobile high-voltage is pacified
Turn into electric automobile field focus of attention entirely.
At present, electricity is main in the high pressure of electric automobile two kinds of control modes, and one kind is utilized in electrokinetic cell inside valency
The mode of high pressure master controller, another kind is the mode of electrokinetic cell outside plus master controller.But both modes are occurring
When main contactor is acted when main contactor connecting fault or other failures, electric control in high pressure can be caused to fail.
The content of the invention
It is an object of the present invention to provide a kind of control method based on the management of electric automobile high-voltage system electrification.This hair
The method that bright use self-inspection and battery manager feed back contactor closure state, can carry out rigorous patrolling to high voltage electric equipment
Row control is collected, the main contactor failure and upper electric control Problem of Failure often occurred in high pressure power up is effectively prevented.
Technical scheme：A kind of control method based on the management of electric automobile high-voltage system electrification, its feature exists
In carrying out in the steps below：
1. when key switch position is located at Key on, entire car controller, electric machine controller, battery manager start certainly
Inspection；
If 2. entire car controller, electric machine controller, battery manager self-inspection do not pass through, from new self-inspection；If full-vehicle control
Device, electric machine controller, battery manager self-inspection pass through, and entire car controller sends allows high-tension electricity order, and enter next stream
Journey；
3. entire car controller receive key switch position signalling, when self-inspection pass through and key switch position be located at Key
During start, entire car controller sends main contactor close command to battery manager, is completed to connect both positive and negative polarity by battery manager
The closure control of tentaculum and preliminary filling relay, and enter downstream；
4. battery manager is in 1s internal feedback main contactor closure states, if feedback time is more than 1s, entire car controller
Judge electricity time-out on electric machine controller, electric machine controller forbids motor to enable, and carries out entire car controller, motor control from newly
Device, battery manager self-inspection；If feedback time is not more than 1s, into downstream；
5. judge whether battery manager feedback both positive and negative polarity contactor closes, if battery manager feedback both positive and negative polarity contactor
Not closed, then battery manager feeds back main contactor closure state from new；If battery manager feedback both positive and negative polarity contactor closure,
Then preliminary filling relay is ready, motor allows to enable, high voltage supply is ready, and enters downstream；
6. battery manager self-inspection, battery manager is from new self-inspection if faulty；If fault-free, dynamical system is just
Thread, it is allowed to drive a vehicle.
In the foregoing control method based on the management of electric automobile high-voltage system electrification, the high-pressure system of the electric automobile
It is made up of electrokinetic cell both positive and negative polarity contactor, preliminary filling electrical circuit and high-voltage load.
Compared with prior art, the present invention is by the side using self-inspection and battery manager feedback contactor closure state
Method, can carry out rigorous logic flow control to high voltage electric equipment, not only can effectively prevent from being passed through in high pressure power up
The main contactor failure and upper electric control Problem of Failure for often occurring, and electric automobile can be alleviated by rainy weather institute is frequent
The critical failures such as the High-Voltage Electrical Appliances short circuit, the electric leakage that cause improve electric automobile as far as possible on the premise of drive efficiency is ensured
Security.
Brief description of the drawings
Fig. 1 is control flow chart of the invention；
Fig. 2 is high-pressure system electrifying timing sequence figure of the present invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limitation according to
According to.
Embodiment.A kind of control method based on the management of electric automobile high-voltage system electrification, as shown in figure 1, pressing following steps
Suddenly carry out：
1. when key switch position is located at Key on, entire car controller, electric machine controller, battery manager start certainly
Inspection；
If 2. entire car controller, electric machine controller, battery manager self-inspection do not pass through, from new self-inspection；If full-vehicle control
Device, electric machine controller, battery manager self-inspection pass through, and entire car controller sends allows high-tension electricity order, and enter next stream
Journey；
3. entire car controller receive key switch position signalling, when self-inspection pass through and key switch position be located at Key
During start, entire car controller sends main contactor close command to battery manager, is completed to connect both positive and negative polarity by battery manager
The closure control of tentaculum and preliminary filling relay, and enter downstream；
4. battery manager is in 1s internal feedback main contactor closure states, if feedback time is more than 1s, entire car controller
Judge electricity time-out on electric machine controller, electric machine controller forbids motor to enable, and carries out entire car controller, motor control from newly
Device, battery manager self-inspection；If feedback time is not more than 1s, into downstream；
5. judge whether battery manager feedback both positive and negative polarity contactor closes, if battery manager feedback both positive and negative polarity contactor
Not closed, then battery manager feeds back main contactor closure state from new；If battery manager feedback both positive and negative polarity contactor closure,
