Abstract
The present invention belongs to a starting control method of an engine in the field of the hybrid control. The present invention includes a hybrid part and a hybrid control system. The engine is restarted under a pure electric work condition and an equipped starting engine is used to start the engine. An output torque of the engine and a motor are adjusted by A PTMU controller to realize the torque requirement of the whole power assembly and to drive the vehicle. When the vehicle is in a still and cool situation, the starting engine and the high-power motor are used to start the engine together. The starting engine or a generator combination used by the present invention improves the economical efficiency of the fuel of the vehicle and reduces the contamination discharged from the engine.
Description
Technical field
The invention belongs to the engine start control method in hybrid power control field.
Background technology
When using traditional starter to realize the engine starting function, its start-up course shows slowly slightly, and have the problem of certain NVH, and have only heavy-duty motor realization engine starting operating mode must bring the of short duration torque break of power drive system, perhaps may bring certain NVH, road-holding property problem, and under the startup time length that allows, use starter motor/electrical generator to come automatic actuation engine can realize starting steady, low noise, startability is better.
Summary of the invention:
The present invention seeks to a kind of engine start control method of strong hybrid electric vehicle; starter motor/generator combination can allow driving engine auto-stop under the operating mode that does not need work; provide the power of powered vehicle by electrical generator work, when needing vehicle to be transformed into engine working mode, can realize smooth-going driving engine quick operated start by electric model.
For achieving the above object, the technical scheme of control method of the present invention is as described below:
A kind of engine start control method of strong hybrid electric vehicle, it is characterized in that: the hybrid power parts that comprise among the present invention have the low-temperature cooling system of protection motor, electronics package, obtain the DC/DC conv of low potential source from high-pressure system, low tension-the power of surging assistant steering device, Motorized vacuum complemental brake system and electric air-conditioning, instrument display system; Hybrid power control system comprises 5CAN line, controller SACU, ACCU, ECU, BMS, TCU, ABS, PTMU, MCU and control wire harness, and this method is implemented following pattern control:
(1), operating under the pure electronic operating mode that power is provided by heavy-duty motor when vehicle, power-transfer clutch is to be in released state, at this moment restart driving engine if desired, under the situation of heavy-duty motor continuation powered vehicle, use the starter motor that is assembled to come start the engine, when engine starting and can oil spout igniting closed power-transfer clutch when power is provided to vehicle, at this moment by the closure state of TCU control clutch, after power-transfer clutch meshed fully, the output torque that the PTMU controller is adjusted driving engine and motor mated the torque demand of realizing whole dynamic assembly and powered vehicle;
(2), when vehicle is in static and is under the cold machine state, use starter motor and the common start the engine of heavy-duty motor.
What adopt in the controlling schemes of strong hybrid electric car of the present invention as shown from the above technical solution, is a kind of vehicle launch controlling schemes that the common co-ordination of heavy-duty motor and miniwatt starter motor realizes the vehicle quick operated start.Starter motor/generator combination can allow driving engine auto-stop under the operating mode that does not need work; provide the power of powered vehicle by electrical generator work, when needing vehicle to be transformed into engine working mode, can realize smooth-going driving engine quick operated start by electric model.The starter/generator that the present invention uses makes up the fuel economy that has improved vehicle and has reduced the engine emission pollutants.

The specific embodiment
Hybrid power car has the hybrid power parts of increase among the present invention: the low-temperature cooling system of protection motor, electronics package, obtain the DC/DC conv of 12V low potential source from the 288V high-pressure system, 12V electricity-the power of surging assistant steering device, Motorized vacuum complemental brake system and electric air-conditioning, instrument display system;
Hybrid power control system comprises among the present invention: 5CAN buses, 8 controllers are controller SACU, ACCU, ECU, BMS, TCU, ABS, PTMU, MCU, control wire harness, and control system software.
The engine starting that the present invention realizes by following control method:
Operating under the pure electronic operating mode that power is provided by heavy-duty motor when vehicle, power-transfer clutch is to be in released state, at this moment restart driving engine if desired, can under continuing the situation of powered vehicle, heavy-duty motor use the starter motor that is assembled to come start the engine, when engine starting and can oil spout igniting closed power-transfer clutch when power is provided to vehicle, at this moment can improve the moment of torsion ingear ride comfort of power drive system by the closure state of TCU control clutch, after power-transfer clutch meshed fully, the output torque that the PTMU controller is adjusted driving engine and motor mated the torque demand of realizing whole dynamic assembly and powered vehicle.
When vehicle is in static and is under the cold machine state, as the ambient temperature under subzero 25degC, starter motor and the common start the engine of heavy-duty motor described in can operational version, realize under this operating mode that big motor helps to start purpose, reduce the torque demand of starter motor, improved startability.
Under the engine starting operating mode according to engine speed and judge engine starting success run up time or the failure principle shown in figure three and figure four.Used parameter-definition is as follows among Fig. 2, Fig. 3:
N
1=driving engine drags threshold value
T
1=driving engine drags the time
N
2=engine starting threshold value
T
2=engine starting maximum time
N
3=turn of engine threshold value
T
3=turn of engine maximum time thresholding
T
4=turn of engine maximum time thresholding
T
PM=premagnetization the time
When vehicle is in staticly, but be not under the above-mentioned cold machine state, as the quiescence under the hot machine situation, starter motor described in can an operational version comes start the engine, can reach higher startability equally, has lower noise, vibration, run up time is shorter, and speed is very fast.
