In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1-Fig. 3, in a kind of embodiment, Motronic control maps idle speed control provided by the utility model, comprises
Step S1: detect motor 1 and whether meet autostop condition;
Step S2: if meet autostop condition, motor 1 autostop;
Step S3: judge whether motor 1 meets automatic starting condition;
Step S4: if meet automatic starting condition, control BSG motor 2 enters power-assisted state, ato unit 1;
Step S5: enter electronics idling;
Step S6: detect whether meet driving conditions;
Step S7: if meet driving conditions, computation requirement moment of torsion;
Step S8: distribute torque is to BSG motor 2 and motor 1;
Step S9: detect whether meet fast running condition;
Step S10: if meet fast running condition, BSG motor 2 exits power-assisted state, controls motor 1 and normally works.
Above-described embodiment increases the detection of driving conditions, in the idling state, if meet driving conditions demand torque to be distributed BSG motor 2 and motor 1 simultaneously, jointly moment of torsion is provided by the two, even if dead time is longer, also can be met the demands by the co-ordination of BSG motor 2 with motor 1, not easily break down, improve the reliability of whole control system and the Security of driving; Meanwhile, by increasing the work of motor 1 under idle conditions, reduce the requirement of BSG motor 2 and battery 5, thus reduce cost of production.
The judgement of autostop condition adopts the BSG start stop system of vehicle self-carrying well known to those skilled in the art, judges.
Automatic starting condition is meet the condition of one of following four:
(1) gear is neutral, and clutch position is greater than the 6th predefined value;
(2) gear is not neutral, and clutch position is greater than the 7th predefined value;
(3) gear is neutral, and the speed of a motor vehicle is greater than the 8th predefined value;
(4) gear is neutral, and battery electric quantity is less than the 9th predefined value;
7th predefined value is greater than the 6th predefined value.
6th predefined value, the 7th pre-sets, the 8th predefined value and the 9th predefined value are recorded by demarcation.Usually, the 6th predefined value is the 10%, seven predefined value is 90%.
This automatic starting condition can ensure that whole vehicle enters the Security of idling mode.
The method of computation requirement moment of torsion comprises
Step S701: detect accelerator pedal position and engine speed;
Step S702: look into demand torque table according to accelerator pedal position and engine speed and obtain demand torque.
Simple to operate by the mode checking in demand torque, efficiency is high.The abscissa of usual demand torque table is engine speed, and y coordinate is accelerator pedal position, different motors 1 and vehicle, and its value is variant, is usually obtained by demarcation.Certain demand torque also directly can be calculated by accelerator pedal position and engine speed and obtain, but calculation of complex, and large by other such environmental effects, it is really situation that the data of calculating can not be reacted, and easily causes the system failure.

Fast running condition, by judging whether the speed of a motor vehicle is greater than the tenth predefined value, if be greater than the tenth predefined value to illustrate that vehicle meets fast running condition, if be not more than the tenth predefined value, illustrates that vehicle does not meet fast running condition.Fast running condition is judged by the speed of a motor vehicle, simple to operate, and be easy to control, and the simplification of program.
Step S10 comprises
Step S101: if do not meet fast running condition, detects battery electric quantity and whether is less than the first predefined value;
Step S102: if battery electric quantity is less than the first predefined value, described BSG motor exits power-assisted state, controls motor 1 and normally works;
If battery electric quantity is not less than the first predefined value, perform step S7.
By the detection to electricity under idling mode, ensure the electric energy described in vehicle, prevent from causing due to feed motor normally to start, thus ensure reliability and the Security of whole system.
Step S6 comprises
Step S61: detect clutch position and whether be greater than the second predefined value;
Step S62: if clutch position is greater than the second predefined value, detects whether gear is neutral;
If clutch position is not more than the second predefined value, then no enough row sails condition;
Step S63: if gear is not in neutral, then meet driving conditions;
If gear is in neutral, then no enough row sails condition.
By the judgement whether clutch position and gear be neutral, vehicle Security in the idling state can be ensured further.
Step S5 also comprises recorded electronic dead time; Step S7 also comprises:
Step S71: if no enough row sails condition, whether detect is misoperation;
Step S72: if misoperation, exits electronics idling, performs step 2.By increasing the judgement of misoperation, the impact of driver's misoperation on whole system can be reduced, thus ensure reliability and the Security of whole system.
Step S72 also comprises:
Step S721: if not misoperation, detection battery electric quantity whether is less than the 3rd predefined value or whether electronics dead time is greater than the 4th predefined value;
Step S722: if battery electric quantity is less than described 3rd predefined value or electronics dead time is greater than the 4th predefined value, exit electronics idling, the described motor of normal startup;
If battery electric quantity is not less than the 3rd predefined value and electronics dead time is not more than the 4th predefined value, perform step S6.
By increasing the judgement to battery electric quantity and electronics dead time after non-misoperation, vehicle Security in the idling state can be ensured, thus improve the reliability of whole system.
Step S71 comprises
Whether step S711: if no enough row sails condition, detect clutch position lower than the 5th predefined value;
Step S712: if clutch position is lower than the 5th predefined value, detects whether gear is neutral;
If clutch position is not less than the 5th predefined value, then not misoperation, perform step S721;
Step S713: if gear is neutral, be then misoperation, perform step S72;
If gear is not neutral, then not misoperation, perform step S721.
By the judgement to clutch position and gear, more accurately can judge whether driver is misoperation, reduce driver's misoperation further to the impact of whole system.
First predefined value described above, the second predefined value, the 3rd predefined value, the 4th predefined value, the 5th predefined value, the 6th predefined value, the 7th predefined value, the 8th predefined value, the 9th predefined value and the tenth predefined value demarcate acquisition by experiment.
