Description

Torsional vibration torque control method and device, electronic equipment, storage medium and vehicle
Technical Field
The application relates to the technical field of automobile power control, in particular to a torsional vibration torque control method and device, electronic equipment, a storage medium and a vehicle.
Background
The active damping function of the automobile refers to that when the speed of a driving motor continuously fluctuates up and down due to abrupt change of road conditions or torque in the power output of the automobile, the motor controller superimposes corresponding torsional vibration torque according to the current speed change rate when the power domain controller normally outputs the required torque so as to inhibit the fluctuation of the speed. The torsional vibration adjusting mode of the existing pure electric vehicle is as follows: the power domain controller performs torsional vibration enabling after detecting torsional vibration of the vehicle; the motor controller outputs torsional vibration torque through the change rate of the motor rotation speed at the moment, and the gain coefficient of the output value is correspondingly adjusted through the actual rotation speed range of the motor at the moment because the torque required for adjusting torsional vibration is different under different rotation speeds. And finally, under the limit of the maximum change rate of the torque, the actual torsional vibration torque is added to the response torque to be output.
However, since the hybrid vehicle model has more torque output of the engine than the electric vehicle model, the following problems occur in the actual use process: under the mixed working condition, as the engine also has torque output, when the motor torque increases/decreases, but the engine torque reversely changes and has larger amplitude, the response torque is opposite to the rotating speed change direction, namely the change direction is the same as the change direction of torsional vibration torque, and if the two change rates are large and are overlapped, the actual overlapped torque exceeds the limit value of the maximum change rate of the motor torque, so that the motor torque is stepped.
Therefore, the existing torsional vibration adjusting mode can bring torsional vibration torque step because of engine intervention operation in the hybrid vehicle, increases the risk of out-of-control torsional vibration of the hybrid vehicle, causes instability of a power system, and influences user experience.

The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
A first embodiment of the present application relates to a torsional torque control method, and fig. 1 is a flowchart of a torsional torque control method according to an exemplary embodiment, as shown in fig. 1, including the steps of:
and step 101, responding to a first torsional vibration enabling request sent by the power domain controller, and acquiring a response torque at a target moment, wherein the target output period of the torsional vibration torque and the motor torque at the last moment is obtained.
Compared with the traditional power automobile, the P2 oil-electricity hybrid system provided by the embodiment of the application has the advantages that a motor and a corresponding coupling mechanism are added, and certain damping elements (such as a torque converter) are omitted, so that the P2 oil-electricity hybrid system comprises the following parts: an engine, a P2M motor, a K0 clutch, a 9AT transmission, a high voltage battery, and low voltage accessories. Because the existing damping method is generally aimed at a pure electric vehicle, only the control of the rotating speed of a motor is reflected, and the response torque of the motor is not judged, the mechanism is hardly affected in the pure electric mode, but in the mixed mode, an engine can also intervene in the power output besides the motor, the original mechanism can cause problems under certain conditions, such as in the mixed mode of a P2 configuration mixed automobile, because the engine also has torque output, when the motor torque increases/decreases, but the engine torque reversely changes and the amplitude is larger, the response torque is opposite to the rotating speed change direction, namely the change direction of the torque is the same as the change direction of the torsional vibration torque, if the two change rates are large and are overlapped together, the actual overlapped torque exceeds the maximum change rate limit value of the motor torque, the motor torque step is caused, and the torsional vibration enabling is carried out in the mixed mode of the motor controller as shown in fig. 3: since the torque curve 2 of the engine is downward, the speed curve 1 of the P2 motor keeps downward trend (i.e. the engine torque at this time varies reversely and has a larger amplitude) even though the motor response torque curve 3 is upward; the torque curve 4 also changes upwards, so that the actual torque (response torque+torque) curve 5 of the motor exceeds the corresponding slope limit, and the motor torque is likely to be suddenly changed.
As can be seen from the foregoing, in the embodiment of the present application, the motor torque includes a response torque and a torsional vibration torque of the motor, where the response torque and the torsional vibration torque of the motor are both corresponding output by the motor controller after the power domain controller sends a corresponding request to the motor controller, because the embodiment of the present application avoids the problem of torsional vibration adjustment, the power domain controller needs to send a first torsional vibration enabling request to the motor controller, so that the motor controller controls the motor to start outputting the torsional vibration torque according to the request, and because the above mentioned needs to determine the current motor torque situation, the response torque at the target moment is obtained, the torsional vibration torque at the last moment and the target output period of the motor torque are both the response torque at the last moment and the response torque at the next moment, and the target period of the motor torque is the minimum output period of the motor torque. The previous time and the next time are two adjacent times, and the two times are determined according to the time when the motor controller responds to the response request about the motor sent by the power domain controller.
And 102, determining the maximum output slope of the torsional vibration torque according to a preset motor torque output slope limiting threshold value, the response torque at the target moment and the target output period.
The preset motor torque output slope limit threshold value in the embodiment of the application is obtained through a plurality of experiments performed in advance, and the torque output by the motor does not generate abrupt change within the threshold value range, so that the slope of the response torque to be controlled to be output by the motor and the torque vibration torque are not larger than the preset motor torque output slope limit threshold value after being overlapped, the output slope of the response torque of the motor can be calculated first, and then the maximum output slope of the torque vibration torque of the motor can be calculated according to the preset motor torque output slope limit threshold value and the output slope of the response torque of the motor. Specifically, according to a preset motor torque output slope limit threshold, the determining the maximum output slope of the torsional vibration torque according to the response torque at the target moment and the target output period includes:
generating a first difference value according to the response torque at the previous moment and the response torque at the next moment;
generating a first ratio according to the first difference and the target output period;
and determining the maximum output slope of torsional vibration torque according to the preset motor torque output slope limiting threshold and the first ratio.
It should be noted that, the step of determining the maximum output slope of the torsional torque may be represented by the formula (1):
K_damping=K_Tq-(|Tq_require - Tq_before|/δT) (1)
wherein, K_Tq is a preset motor torque output slope limit threshold, δT is a target output period of motor torque, tq_required is a response torque at the next moment, tq_before is a response torque at the last moment, K_damping is a torque maximum output slope determined according to the preset motor torque output slope limit threshold, the response torque at the target moment and the target output period, |Tq_required-Tq_before|/δT is the output slope of the response torque of the motor actually obtained.
And step 103, determining a first torsional vibration torque output range according to the torsional vibration torque at the last moment, the maximum output slope of the torsional vibration torque and the target output period.
In the embodiment of the present application, the maximum torque output slope of the motor is determined in the above step, and because the slope is set by a preset motor torque output slope limiting threshold, the motor can be prevented from suffering from abrupt change only by overlapping the slope of the response torque of the motor with the slope of the torque and then being smaller than the threshold, so that the range of the torque output by the motor can be calculated according to the obtained maximum torque output slope of the motor, specifically, the maximum torque output slope of the torque and the target output period are determined according to the torque at the last moment, and the first torque output range is determined, including:
generating a first target range according to the maximum output slope of the torsional torque and the target output period;
and determining a first torsional vibration torque output range according to the first target range and the torsional vibration torque at the last moment.
It should be noted that, the step of determining the output first torsional vibration torque output range may be represented by the formula (2):
(|Tq_damping – Tq’_damping|/δT)≤K_damping (2)
wherein, K_damming is the maximum output slope of torsional vibration torque (namely the maximum slope of torsional vibration torque output), tq' _damming is the torsional vibration torque at the last moment, and Tq_damming is the first torsional vibration torque output range which is determined to be output according to the first target range and the torsional vibration torque at the last moment.
The method comprises the steps of responding to a first torsional vibration enabling request sent by a power domain controller, obtaining response torque at a target moment, limiting a threshold value according to a preset motor torque output slope, determining a maximum output slope of torsional vibration torque according to the response torque at the target moment and the target output period, and determining a first torsional vibration torque output range according to the torsional vibration torque at the last moment, the maximum output slope of torsional vibration torque and the target output period. According to the torque output slope limiting method and device, the output slope of the torsional vibration torque is limited through the preset motor torque output slope limiting threshold value, so that the output range of the first torsional vibration torque is controlled, the situation that the torque of the motor is suddenly changed and torsional vibration torque is stepped due to torsional vibration torque is avoided, the risk of out-of-control torsional vibration of the hybrid electric vehicle is effectively reduced, the stability of a power system is improved, and the user experience is improved.
A second embodiment of the present application relates to a torsional torque control method, fig. 2 is a flowchart of another torsional torque control method according to an exemplary embodiment, as shown in fig. 2, comprising the steps of:
step 201, a motor torque request of a target value sent by a power domain controller is received.
After the motor controller is electrified and initialized, the motor controller starts to judge whether a state of outputting 0 torque exists or not, so that whether the torque is in a torque control dead zone (namely a torque response area which is not in response to a torque request between positive torque and negative torque) or not is judged, because the vehicle is in a parking state and cannot generate torsional vibration when the motor is in no torque output, but the vehicle can still run at a high speed due to intervention of an engine even if the motor is not in torque output in running of the hybrid electric vehicle, when the motor is adjusted according to an original scheme, motor torque steps are caused by dead zone strategies, as shown in fig. 4, when the response torque of the motor controller is 0NM, the reference of torsional vibration torque is 0NM, the area between two dotted lines is the torque dead zone, and the actual torque can be seen to cross the torque dead zone back and forth at the moment, so that impact is caused.
In order to solve the above problem, firstly, the torque state at that time is judged, that is, the power domain controller needs to send out a motor torque request to the motor controller, wherein the sent motor torque request comprises a specific target value of the requested torque, and the motor torque request carrying the target value corresponds to the request of the response torque of the motor.
Step 202, controlling the response torque of the motor output target value according to the motor torque request.
In the embodiment of the application, the motor controller responds to the torque requested by the power domain controller and outputs the response torque of the target value.
In step 203, a timer is started in case it is detected that the target value of the response torque is smaller than the first threshold value.
In the embodiment of the application, a timer is started under the condition that the target value of the response torque is detected to be smaller than the first threshold value. The first threshold is a value near the 0 torque range set by man, and may be 3NM or 2NM, and the present application is not limited herein.
Step 204, confirming that the motor is in a 0 torque output state when the timing of the timer is detected to be larger than the second threshold value.
In the embodiment of the application, the timer is started under the condition that the target value of the response torque is detected to be smaller than the first threshold value, but if the condition occurs only for a short period of time, the motor is not considered to be in a 0-torque output state at the moment, and only under the condition that the timing of the timer is larger than the second threshold value, namely after the output lasts for a period of time, the motor is considered to be in the 0-torque output state at the moment, wherein the second threshold value is a preset time value and is not too long nor too short, and can be set to be 5S,7S,8S and the like, so that misoperation after the occurrence of accidental conditions is avoided, abrupt change of the motor torque of an automobile caused by long-time non-processing is avoided, and the experience of a user is influenced.
Step 205, obtaining a preset torsional torque value in response to a second torsional enabling request sent by the power domain controller.
In the embodiment of the application, after the motor is determined to be in a 0 torque output state, the power domain controller sends a second torsional vibration enabling request of the motor to the motor controller, the motor controller has the function of detecting the self torsional vibration torque and generating a self working state to the power domain controller, the output torsional vibration torque can be automatically adjusted, and in order to acquire the output convergence range of the second torsional vibration torque, a preset torsional vibration torque value is acquired firstly in response to the second torsional vibration enabling request sent by the power domain controller, wherein the preset torsional vibration torque value is the maximum value of the allowable output of the torsional vibration torque.
And 206, determining a calibration reference offset of the second torsional vibration torque according to the preset torsional vibration torque value.
In the embodiment of the application, the preset torsional vibration torque value is the maximum value of allowable output of torsional vibration torque, the calibration reference offset of the second torsional vibration torque is determined according to the preset torsional vibration torque value, namely, the preset torsional vibration torque value is divided by 2 to obtain the calibration reference offset of the second torsional vibration torque, and if the preset torsional vibration torque value is 20NM, the calibration reference offset of the second torsional vibration torque at the moment is 10NM.
Step 207, determining an output convergence range of the second torsional vibration torque according to the first threshold value and the preset torsional vibration torque value.
In the embodiment of the application, the first threshold value is used for judging whether the motor torque is in the dead zone or not, so that the torsional vibration torque cannot shuttle back and forth in the dead zone, the minimum value of the torsional vibration torque is required to be larger than the first threshold value, and the maximum value of the torsional vibration torque is smaller than the preset torsional vibration torque value because the preset torsional vibration torque value is the maximum value of the torsional vibration torque allowed to be output, so that the output convergence range of the second torsional vibration torque is determined according to the first threshold value and the preset torsional vibration torque value. As shown in fig. 5, by adjusting the calibration reference offset of the second torsional vibration torque, the output convergence range of the second torsional vibration torque is between the first threshold value and the preset torsional vibration torque value, so that the torsional vibration torque is prevented from shuttling back and forth in the dead zone, and the torque step of the motor is avoided.
