It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.
In the description of the present specification, the descriptions of the terms "embodiment," "one embodiment," and the like mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or embodiment is included in at least one embodiment or illustrated embodiment of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same examples or implementations. Furthermore, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or implementations.
Referring to fig. 1, an embodiment of the present invention provides a vehicle operation control method, which is applied to a motor controller, and includes the steps of:
judging whether the motor and other motors have faults or not;
in this embodiment, the motors, i.e. the motors of the wheels of the vehicle, control the wheels to run through the motors, each motor has a motor controller, specifically, as shown in fig. 3, an MCU (micro control unit) can be in communication connection with a central controller of the vehicle, so as to receive information such as operations and sensors, and is controlled by the central controller, and each MCU is in communication connection with each other, so as to monitor information of other motors, identify fault conditions, and the like, and the above vehicle running control method can be applied to one motor controller, so as to determine fault conditions of the motor and the other motors by acquiring information of the own motor (the motor) and information of other motor MCUs.
The method of the embodiment can be applied to a four-wheel drive vehicle, and correspondingly, the controller executing the method can acquire the fault information of the motor and the fault information of the other three motors.
The fault may be a hard fault which cannot be recovered in a short time in the vehicle, and for a soft fault which can be recovered in a short time such as over-temperature/under-voltage/over-current, the vehicle central controller performs coordinated control to recover to normal.
When the motor is not failed and the rest motors are failed and the vehicle can drive, acquiring the position condition of the failed motors and the number of the failed motors;
in this embodiment, the position condition may be determined by determining position pointers corresponding to the motor and the failed motor, where the position condition may be specific position information such as front left, front right, rear left, rear right, etc. for a four-wheel drive vehicle, or may be relative position information between the motor and the failed motor or several failed motors.
And activating a fault tolerance strategy for controlling the torque of the motor according to the position condition and the quantity.
Therefore, in this embodiment, since the motor does not have a fault and can normally operate, when the motor and the motor fail, the fault-tolerant strategy to be executed by the motor is more reasonably determined by combining the position condition and the number of actual failed motors, therefore, when the motor of the vehicle has a wheel failure, the distributed driving function is degraded by performing fault-tolerant control on the current motor, the torque of the current motor is reasonably controlled to form a reliable precursor or a reliable backdriving form, driving is continuously supported, so that the driving safety is ensured, the occurrence of dangerous situations is reduced, meanwhile, the invention realizes the decentralization control by implementing a certain degree of fault post-processing on the motor side, and does not respond to the abnormal torque of central coordination under the abnormal situations such as optimizing the distribution algorithm or the coordination control of the central controller, so that the dangerous situations such as instability can be further avoided.
In an alternative embodiment of the invention, said activating a fault tolerant strategy for controlling the torque of said present motor in dependence of said position condition and said number comprises:
when the number is one and the fault motor and the motor are positioned at the coaxial position of the vehicle, judging whether the vehicle activates yaw stability control;
if yes, controlling the torque of the motor according to the slip condition of the vehicle.
Referring to fig. 2, in this embodiment, when the motor on the other side coaxial with the motor fails, both wheels of the other axle can normally operate at this time, and it is further determined whether the yaw stability control is activated or not, if not, it indicates that the vehicle has no slip, so that under the condition that a plurality of wheels are normal, the wheels can be limited according to the driving stability principle, for example, the maximum torque limit (steady-state target output) of the wheels is slowly reduced, so as to ensure the stable operation of the vehicle.
When the yaw stability control is activated, the vehicle may slip, so in the embodiment of the invention, according to the slip condition of the vehicle, a target of a reference vehicle speed/steering angle is set to control the torque of the motor based on the principle of low-speed power/high-speed stability, and the target is used as a fault-tolerant strategy of the wheels to ensure the safety of the overall running of the vehicle.
Specifically, in this embodiment, the controlling the torque of the motor according to the slip condition of the vehicle includes:
when the wheel with the different axle on the same side as the wheel is slipped, controlling the motor to increase a first preset torque, wherein the first preset torque is matched with the lost driving torque of the wheel with different axle;
when the axle where the wheel is positioned sideslips, controlling the torque of the motor to be reduced at a first preset torque limiting speed;
when the other axle shaft which is different from the own wheel slips, the own motor is controlled to increase a second preset torque, wherein the second preset torque is matched with the driving torque and the yaw torque which are lost by the other axle shaft.
In this embodiment, taking the present wheel as the left front wheel as an example, the off-axis wheel on the same side of the present wheel is the left rear wheel, when TCS slipping (tracking control system) occurs on the left rear wheel, the left front wheel can bear the torque transferred from the driving force required by driving, at this time, the present motor is controlled to increase the torque, so as to realize the transfer and bearing of the driving torque, that is, increase the first preset torque, which is the driving torque lost by the off-axis wheel slipping, thereby ensuring the stable running of the vehicle.
When the front axle where the left front wheel is located is subjected to ESC (electronic stability system) sideslip, at this time, the front axle push torque is transferred to the rear axle, and due to the failure of the right front wheel, the front axle where the left front wheel is located needs to be subjected to torque reduction, so that the motor of the left front wheel is subjected to slow torque reduction control to limit the torque capacity, and the process can respond to the yaw torque distribution of the central controller, wherein the first preset torque limiting speed can be set according to the actual situation, and is not limited.
When ESC sideslip occurs to the other axle of the front left wheel heteroaxle, namely the rear axle, at the moment, the rear axle swings the tail, the driving torque is transferred forwards, the driving torque of the rear axle needs to be reduced, meanwhile, the differential torsion yaw moment generated by the left wheel and the right wheel is limited, so that the motor is controlled to increase the second preset torque, the second preset torque is matched with the driving torque and the yaw torque lost by the other axle, and therefore, the fact that new sideslip cannot occur is ensured, and the vehicle runs normally is ensured. For example, if the driver is driving the vehicle to turn right, i.e. the positive torque generated by the motor of the left front wheel satisfies the driving and right yaw moments, the torque capacity of the one-sided driving/braking is released at the moment of ESC activation, and the torque capacity of the one-sided driving/braking is responsive to the request torque of the central controller, thereby preventing the vehicle from sideslip and ensuring normal operation.
In an alternative embodiment of the invention, said activating a fault tolerant strategy for controlling the torque of said present motor in dependence of said position condition and said number comprises:
when the number is three or the number is two and the two fault motors are positioned at the same side position of the vehicle, controlling the torque of the motor to be reduced to a third preset torque at a second preset torque limiting speed.
Referring to fig. 2, in this embodiment, for a four-wheel drive vehicle, when all the remaining three motors fail, or there are two motor failures on the same side (for example, the motor is left front, and the other two motor failures on the same side are right front and right rear), the vehicle cannot keep running at this time, so that the motor can be controlled to quickly torque up to a third preset torque to prevent dangerous situations of the vehicle, where the third preset torque can be set to 0Nm, and the second preset torque limiting speed can be set according to actual situations, and is not limited herein.
In an alternative embodiment of the invention, said activating a fault tolerant strategy for controlling the torque of said present motor in dependence of said position condition and said number comprises:
when the number is two and the two failed motors are located at diagonal positions of the vehicle, a control instruction for causing a central controller to coordinate output power is generated, and the present motor is controlled to maintain the current torque and to respond to part of the output power.
The motor is taken as an example of a motor of a left front wheel of a vehicle, at the moment, the motor at a diagonal position is the motor of a right front wheel of the vehicle and the motor of a left rear wheel of the vehicle, when the two motors are in fault, the motor can not limit torque, namely keep the current torque, at the moment, the central controller coordinates and outputs power according to control requirements, and the motor responds to partial power to execute control, so that the stable running of the vehicle is ensured.
In an alternative embodiment of the invention, said activating a fault tolerant strategy for controlling the torque of said present motor in dependence of said position condition and said number comprises:
when the number is two and the two fault motors are located at the coaxial positions of the vehicle, a control command for enabling the central controller to coordinate output power and vehicle yaw torque is generated, and the current torque is kept by the fault motors.
In this embodiment, the fault motor is a left rear motor and a right rear motor of the rear axle of the vehicle, and both wheels of the front axle of the vehicle can normally run at the moment, so that the motor does not limit torque, and the central controller coordinates and outputs power and yaw torque of the vehicle, so that the vehicle maintains certain drivability.
In an alternative embodiment of the present invention, the vehicle operation control method further includes:
when the motor is judged to be faulty, determining the fault condition of the motor, and limiting the torque of the motor according to the fault condition; and/or
When the other motors are judged to be faulty and the vehicle cannot run, controlling the torque of the motor to be reduced to a third preset torque at a third preset torque limiting speed.
In this embodiment, when the motor fails, the torque is limited according to the failure of the body, and when the other motors fail, if the vehicle cannot drive, the torque can be limited to a third preset torque, such as slowly limited to 0Nm, so as to ensure reasonable control of the motor of the vehicle and prevent dangerous situations. The third preset torque limiting speed may be set according to practical situations, and is not limited herein.

the judging module is used for judging whether the motor and other motors have faults or not;
