Example 1:
in the present embodiment, referring to fig. 1, there is provided a controller 1 including a first control module 110 and a second control module 120;
the first control module 110 is electrically connected to the second control module 120, and the first control module 110 and the second control module 120 can receive the trigger signal respectively and simultaneously;
the first control module 110 and the second control module 120 are respectively configured to output electric energy according to a trigger signal and at least one preset condition, where the first control module 110 is configured to send one of the preset conditions to the second control module 120.
In the present embodiment, the first control module 110 is preferably configured as a high pressure control module, and the second control module 120 is preferably configured as a low pressure control module. It should be appreciated that in other embodiments, the first control module 110 may be both a high pressure control module and a low pressure control module; similarly, the second control module 120 may be a high-pressure control module or a low-pressure control module.
In practical applications, the control object of the controller 1 is a dual coil motor. In the present embodiment, a dual coil motor is provided as a dual coil motor having a high voltage coil and a low voltage coil.
The first control module 110 is electrically connected to the high-voltage coil of the dual-coil motor, and the second control module 120 is electrically connected to the low-voltage coil of the dual-coil motor.
The first control module 110 is configured to generate a fault electrical signal, which is one of the preset conditions, and to send the fault electrical signal to the second control module 120.
In this embodiment, the first control module 110 and the second control module 120 are electrically connected, and the first control module 110 may generate a fault electrical signal and may send the fault electrical signal to the second control module 120; in other words, the second control module 120 is at least used for monitoring the first control module 110 through the fault electric signal, when the second control module 120 receives the fault electric signal sent by the first control module 110, the first control module 110 is interrupted, and the second control module 120 is turned on, otherwise, when the second control module 120 does not receive the fault electric signal sent by the first control module 110, the first control module 110 is turned on, and the second control module 120 is interrupted.
In practical application, the control purpose of the controller 1 is to drive the dual coil motor to rotate. In the embodiment, when the first control module 110 is turned on, the first control module 110 is preferentially adopted to drive the dual-coil motor to rotate; in the case where the first control module 110 is interrupted due to a failure, the second control module 120 is used to drive the dual coil motor to rotate.
In practical application, whether the controller 1 needs to drive the dual-coil motor to rotate or not needs to make a judgment result according to the received trigger signal. When the controller 1 of the present embodiment is applied to a steering oil pump having a dual coil motor, the controller 1 on the steering oil pump is electrically connected to a VCU of a vehicle, and a CAN bus protocol is executed between the VCU and the controller 1, so that the controller 1 CAN receive a CANH signal and a CANL signal sent by the VCU, and the CANH signal and the CANL signal are trigger signals; the first control module 110 and the second control module 120 may receive the CANH signal and the CANL signal at the same time, respectively, and the logic values of the CANH signal and the CANL signal are used as the basis for whether to actually trigger the first control module 110 and the second control module 120, where the logic values of the CANH signal and the CANL signal are only '0' and '1'.
When the controller 1 only receives the trigger signal, if the logical value of the trigger signal is 1, it indicates that the vehicle is already in the running state, and the vehicle is not subjected to steering operation at this time, so that the first control module 110 and the second control module 120 of the current controller 1 are respectively in the interrupted state, and the first control module 110 and the second control module 120 do not need to drive the dual-coil motor;
when the controller 1 receives only the trigger signal, if the logic value of the trigger signal is 0, it indicates that the vehicle is already in a running state and the vehicle is making a steering operation at that time, therefore, the first control module 110 and the second control module 120 of the current controller 1 should make a judgment according to whether there is a fault electric signal of the first control module 110, and the first judgment result is: if the logic value of the trigger signal is 0 and there is no fault electrical signal, the second control module 120 is interrupted, and the first control module 110 is turned on, that is, the first control module 110 is adopted to drive the dual-coil motor; the second judgment result is: if the logic value of the trigger signal is 0 and there is a fault electrical signal, the first control module 110 is interrupted, and the second control module 120 is turned on, that is, the second control module 120 is used to drive the dual-coil motor.
In practical applications, the first control module 110 and the second control module 120 of the controller 1 respectively have a control circuit and a driving circuit, wherein the driving circuit is actually electrically connected to the dual-coil motor, and the control circuit is used for controlling the conduction and the interruption of the driving circuit; in other words, if the first control module 110 needs to be turned on, it is required that the logic value of the trigger signal received by the first control module 110 is 0, and the first control module 110 at least does not generate a fault electrical signal, and the control circuit can turn on the driving circuit only when the control circuit is in the powered state, so as to turn on the first control module 110; the on condition of the second control module 120 is similar to the on condition of the first control module 110, and is not described herein again. The preset conditions set forth in the foregoing actually include at least whether the first control module 110 generates a fault electric signal and whether the second controller 1 receives the fault electric signal. It should be understood that, in the following, additional conditions are also proposed as one of the preset conditions, and are not mentioned here for the time being.
The electric energy output by the first control module 110 is a first electric energy, the electric energy output by the second control module 120 is a second electric energy, and the voltage of the first electric energy is higher than that of the second electric energy.
The first control module 110 may receive a first input power and a second input power, wherein the second input power may be converted into the first power;
the second control module 120 may receive a first input power, wherein the first input power may be converted to a second power.
The control circuits of the first control module 110 and the second control module 120 are powered respectively from the low-voltage power supply of the vehicle; the voltage of the low voltage power supply should be below 48V, for example: 24V and 48V; in practice, when the vehicle is started, the low voltage power supply can deliver electrical energy to the control circuit.
The first electric energy output by the driving circuit of the first control module 110 comes from a high-voltage power supply of the vehicle; the voltage of the high voltage power supply is typically above 300V, for example: the voltage of the passenger electric car may be set to 336V, 384V, and the voltage of the commercial electric car may be set to 580V; in practical applications, when the control circuit switches on the driving circuit, the electric energy output by the high-voltage power supply is converted into the first electric energy through the driving circuit, and the first electric energy is transmitted to the high-voltage coil of the dual-coil motor, that is, the dual-coil motor is driven by the first control module 110.
The second electric energy of the driving circuit of the second control module 120 comes from a low-voltage power supply of the vehicle, where the low-voltage power supply and the aforementioned low-voltage power supply are the same low-voltage power supply; in practical applications, when the control circuit switches on the driving circuit, the electric energy output by the low-voltage power supply is converted into the second electric energy through the driving circuit, and the second electric energy is transmitted to the low-voltage coil of the dual-coil motor, that is, the dual-coil motor is driven by the second control module 120.
In practical applications, when the controller 1 is disposed on a steering oil pump having a dual-coil motor and a vehicle is subjected to a steering operation during operation, if the first control module 110 fails, the dual-coil motor is subjected to a loss of electric energy, which results in a situation where the vehicle loses the steering assist provided by the steering oil pump; at this time, the second control module 120 can receive the fault electric signal sent by the first control module 110, so that the driving circuit of the second control module 120 is turned on, and the low-voltage coil of the dual-coil motor at this time can receive the electric energy sent by the second control module 120, and the dual-coil motor continues to work by using the electric energy sent by the second control module 120, so that the vehicle can be prevented from losing the assistance provided by the steering oil pump.
In the prior art (a dual-source electric hydraulic power steering pump system, application number: 202020225856.X), 'when the dual-source electric hydraulic power steering pump is normally started, a high-voltage motor winding and a low-voltage motor winding work simultaneously', and in other words, the high-voltage motor winding and the low-voltage motor winding of the dual-source electric hydraulic power steering pump can receive electric energy simultaneously.
In the present embodiment, the steering oil pump with the dual-coil motor (which is equivalent to the dual-source electric hydraulic power steering pump in the prior art) can only receive the electric energy generated by the first control module 110 of the controller 1, or receive the electric energy generated by the second control module 120, so that one of the high-voltage coil and the low-voltage coil of the dual-coil motor can work.
Therefore, the controller 1 provided in this embodiment solves the technical problem of how to provide a control component for a dual-winding motor and capable of saving electric energy on the premise of avoiding the loss of the steering assist of the vehicle in the prior art.
Further, in the foregoing, the dual coil motor may receive one of the first electric energy and the second electric energy, wherein, if the dual coil motor is set as a dc motor, the high voltage coil and the low voltage coil should be respectively supplied with the first electric energy and the second electric energy in direct current; if the dual coil motor is configured as an ac motor, the high-voltage coil and the low-voltage coil should be supplied with first electric energy and second electric energy, respectively, at an ac current.
Specifically, if the dual coil motor is set as a dc motor, the driving circuit of the first control module 110 should receive a first input power in a dc form from the high voltage power supply, and the driving circuit is configured to convert the first input power in the dc form into a first power, and the first power is directly transmitted to the high voltage coil of the dual coil motor; and, the driving circuit of the second control module 120 should receive the second input power in direct current from the low voltage power source, and the driving circuit is used to convert the second input power in direct current into the second power, which is directly transmitted to the low voltage coil of the dual coil motor.
Specifically, if the dual coil motor is provided as an ac motor, referring to fig. 1, the first control module 110 is provided with a first inverter 111; the second control module 120 is provided with a second inverter 121;
the second input electric energy is converted into the first electric energy by the first inverter 111;
the first input power is converted into a second power by the second inverter 121.
It should be understood that the first inverter 111 is part of the driving circuit of the first control module 110 and the second inverter 121 is part of the driving circuit of the second control module 120.
The driving circuit of the first control module 110 should receive a first input power in a dc state from the high-voltage power supply, the first inverter 111 is configured to convert the first input power in the dc state into a first power in an ac state, and the first power in the ac state is directly transmitted to the high-voltage coil of the dual-coil motor; and, the driving circuit of the second control module 120 should receive the first input power in the dc state from the low voltage power source, and the second inverter 121 is configured to convert the first input power in the dc state into the second power in the ac state, and the second power in the ac state is directly transmitted to the low voltage coil of the dual coil motor.
Further, the second control module 120 may receive a second electrical signal;
the second electrical signal is used to generate another one of the preset conditions.
Among them, in the foregoing, it has been proposed: when the first control module 110 of the controller 1 malfunctions, the high-voltage coil of the dual-coil motor is made to lose electric power, which may cause the vehicle to lose the negative effect of the assist force provided by the steering oil pump.
In practical applications, there is another situation that may cause the vehicle to lose the negative effect of the power assistance provided by the steering oil pump, specifically: in the case where the first control module 110 does not generate a failure electric signal, there is a possibility that a failure is formed at a circuit between the controller 1 and the dual coil motor or at a high voltage coil of the dual coil motor, resulting in a failure in rotation of a motor shaft of the dual coil motor.
Therefore, the second control module 120 obtains the rotation speed electrical signal sent by the dual-coil motor, and uses the rotation speed electrical signal as the second electrical signal to determine whether the current high-voltage coil of the dual-coil motor can drive the motor shaft to rotate. A rotation speed threshold value is stored in the second control module 120 in advance, the rotation speed electrical signal is converted into a rotation speed value, the rotation speed value is compared with the rotation speed threshold value, and if the rotation speed value meets the rotation speed threshold value, the current high-voltage coil of the double-coil motor is represented, and the motor shaft can be driven to rotate; on the contrary, if the rotating speed value does not meet the rotating speed threshold value, the high-voltage coil of the current double-coil motor is represented, and the motor shaft cannot be driven to rotate.
It should be understood that the rotational speed threshold may be a reference value, such as: the reference value is greater than 0, when the rotating speed electric signal is received, if the rotating speed value is 0, the rotating speed threshold value is not met, and if the rotating speed value is greater than 0, the rotating speed threshold value is met. And comparing the rotating speed electric signal with the rotating speed threshold value to obtain another preset condition.
The second electrical signal may be generated using prior art structures, such as: the Hall sensor can be arranged on the double-coil motor, and the second electric signal can be obtained and output by acquiring the rotating speed of the motor shaft of the double-coil motor through the Hall sensor.
