The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

As fig. 1 to 4, the utility model relates to a control system that petrol-electric hybrid passenger train engine opened and stops, including accumulator jar 1, digital instrument 2, hybrid controller 3, starter 5, engine 6, ECU7, accelerator pedal 8 and have freewheeling diode's five-claw relay 4.

The engine 6 and the accelerator pedal 8 are correspondingly connected with the ECU, and

pins

03 and 04 in the ECU are connected with the anode of the storage battery 1.

The starter 5 is connected with a pin 87 in the five-claw relay 4, a pin 86 in the five-claw relay 4 is connected with a pin A-3B in the connection of the hybrid controller 3, a pin 85 in the five-claw relay 4 is grounded, a pin 30 in the five-claw relay 4 is connected with the anode of the storage battery 1, and the digital instrument 2 is simultaneously connected with the hybrid controller 3, the ECU and the anode of the storage battery 1.

The A-3C pin in the hybrid controller 3 is connected with an ON switch S1, and the ON switch S1 is connected with the anode of the accumulator jar 1. The A-1A pin in the hybrid controller 3 is connected with a rear flameout switch S2; the A-1B pin is connected with a mixed mode switch S3; the A-2A pin is connected with a pure electric mode switch S4; the A-2B pin is connected with a forced charging mode switch S5; the connection of the A-3A pin activates switch S6.

The working principle of the freewheeling diode five-claw relay 4 is as follows: pin 86 is the control pin of the relay coil, pin 85 is the ground wire of the relay coil, pin 30 is connected to the positive pole of the storage battery, pin 87 is the normally open pin, pin 30 and pin 87 are connected when the relay is working, and pin 87a is the normally open pin, pin 30 and pin 87a are connected when the relay is off.

The HCU (hybrid controller 3) controls whether the A-3B pin outputs high level by switching in signals of S2, S3, S4, S5 and S6 and judging the overall state of the vehicle; the starting of the engine needs to be controlled by a five-claw relay, and the control of the relay is controlled by an A-3B pin; the discussion focuses on whether the starter works or not under the condition that the engine is started, and whether the engine is started or not is directly determined.

The logical outputs of A-3B are: a static state: and outputting 10 seconds if the START signal is effective, the engine speed is less than 350rpm, the rear door signal is ineffective, the rear flameout signal is ineffective and the neutral signal is effective.

A static state: and outputting 10 seconds if the rear starting signal is effective, the engine rotating speed is less than 350rpm, the rear door signal is effective, the rear flameout signal is ineffective and the neutral signal is effective.

When the pure electric mode is switched to the hybrid mode or the conventional mode: the pressure is lower than 0.65 MPa.

When the pure electric mode is switched to the hybrid mode or the conventional mode: the battery voltage is less than 24V for 40s or less than 22V for 10 s.

When the S5 switch is active, the vehicle stops running, the engine is started and charging of the electric machine negative torque begins.

When any condition is met, the A-3B controls the relay to work so as to control the starter to work, and the engine is started.

When the HCU judges that the whole vehicle does not need the engine to work, the engine needs to be flamed out, and the conditions are as follows:

s4 the pure electric mode switch is effective; the accelerator is continuously released for a few seconds or the brake is continuously stepped on.

When the engine needs to be shut down, the engine ECU and the HCU are within the same CAN network, and a shutdown command CAN be sent through the CAN network, as shown in the following table (the table is a shutdown command).

Description of the drawings: the HCU continues to fire 01 during the shutdown until the engine stalls. No shutdown is required or after a shutdown has occurred, 00 is sent.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
