Each of the driving motors is connected to an application specific integrated circuit (ASIC) that is optimally designed to control and detect a state of the driving motor.

The on-demand semiconductor 300 is connected by a micro control unit (MCU) 200 which issues a control command to the driving motor, and the micro control unit 200 controls the operation of each driving motor. It acts as a CPU.

The micro control unit 200 is connected to an electronic control unit (ECU) 100 that controls all operations of the vehicle, and the driving motor is based on a control command of the electronic control unit 100. To control.

As shown in FIG. 2, in the schematic diagram of the motor control system for a vehicle according to the present invention, the electronic control unit 100 is communicatively connected to the micro control unit 200.

The micro control unit 200 is implemented with control logic, that is, application logic for each driving motor 400.

Based on this, a specific control command may be given to the application-specific semiconductor 300, or another control command may be issued based on the information detected by the application-specific semiconductor 300.

The custom semiconductor 300 and the micro control unit 200 may be connected to a serial peripheral interface (SPI) to exchange control commands and sensed information.

The custom semiconductor 300 includes a regulator 310, a controller 320, an AD converter 330, an error detector 340, a gate driver 350, a temperature sensor 360, a current sensor 370, and a voltage sensor. 380 and the H-bridge 390 are implemented in hardware.

On the other hand, the outside of the custom semiconductor 300 is provided with a position sensor 410 for sensing the position of the flap or damper or the rod connecting them and the drive motor 400.

Meanwhile, a temperature sensor 420 for measuring the temperature of air may be provided outside the custom semiconductor 300.

The position sensor 410 is preferably configured as a hall sensor mounted on an actuator or a valve to detect a change in magnetic flux density to detect a change in position of a flap or damper, but is not limited thereto.

The drive motor 400 is connected to the custom semiconductor 300.

Therefore, according to the control command output from the micro control unit 200, the control command for the drive motor is output from the application-specific semiconductor 300, and the drive motor 400 operates accordingly.

The regulator 310 serves to guide the voltage supplied from an external power source such as a battery to be stably transmitted to the micro control unit 200 and the gate driver 350.

In this embodiment, a battery voltage of 12V is applied to the regulator 310, and the regulator is reduced to 2.5V or 5V, which is then applied to the gate driver 350, the micro control unit 200, and the custom semiconductor 300. ) Serves to supply to the external position sensor 410.

In addition, by changing the PID control parameter, the response speed of the driving motor 400 may be changed, and an error may be reduced.

The input of the controller 320 is the difference between the current position and the target position of the flap or damper. Therefore, the controller 320 performs a control function to eliminate this difference.

The AD converter 330 converts the analog signal detected by the temperature sensor 360 or the current sensor 370, the voltage sensor 380, and the position sensor 410 implemented in the custom semiconductor 300 into a digital signal. To deliver to the micro control unit 200.

The error detector 340 serves as a reference based on a value detected by the temperature sensor 360, the current sensor 370, the voltage sensor 380, and the position sensor 410 implemented in the application-specific semiconductor 300. By judging from the range or the reference value, it is to determine whether the current operating state of the drive motor 400 is an error state or not.

That is, before the micro control unit 200 determines the operation error of the driving motor 400, the error detection unit 340 determines whether the error is itself and transmits the error to the micro control unit 200.

In addition, the error detection unit 340 not only the voltage or temperature value input from the external sensor but also the voltage, current, and temperature of the inside of the custom semiconductor 300 itself, the temperature sensor 360, the current sensor 370, and the voltage sensor. If an abnormality occurs by monitoring through 380, it is transmitted to the micro control unit 200.

Therefore, the bad condition is quickly determined and transferred to the micro control unit 200, while the application-specific semiconductor 300 itself performs a protection function of the application-specific semiconductor 300 or the driving motor 400. .

That is, after a quick error determination, it is desirable to protect the system by quickly preventing overcurrent or overvoltage from being supplied to the system.

On the other hand, the H-bridge 390 is provided with four switches, connected to the drive motor 400, and enables the forward and reverse rotation of the drive motor using a battery voltage.

That is, when two of the four is on and the other two are off, the forward rotation of the drive motor 400, the switch that was off is turned on, when the switch was turned off, the drive motor 400 Reverse rotation is made.

The gate driver 350 is provided between the regulator 310 and the controller 320 and the H-bridge 390.

In order for the driving motor 400 to operate, signals flow in the order of the regulator 310, the gate driver 350, and the H-bridge 390.

The controller 320 outputs a direction control signal for determining the direction of the driving motor 400 and a pulse width modulation signal PWM for controlling the output of the driving motor 400.

The gate driver 350 generates a gate signal for turning off each switch constituting the H-bridge 390 and transmits the gate signal to the H-bridge 390.

3 is a block diagram showing the control flow of the control system according to the present invention.

As shown in FIG. 3, the application-specific semiconductor 300 according to the present invention is connected to the micro control unit 200 provided to communicate with the electronic control unit 100.

The control including the controller 320 and the driving motor 400 provided in the custom semiconductor 300 is implemented as negative feedback control.

Wherein the controller 320 is implemented by PID control, each control parameter is provided to be changeable, it is possible to reduce the error or improve the response in accordance with the state of the drive motor.

The driving motor 400 is connected to an H-bridge having four switches (N-channel FETs) 391 and is provided to be capable of forward rotation or reverse rotation.

The gate driver 350 is provided between the regulator 310 and the H-bridge 390 and between the controller 320 and the H-bridge 390.

As described above, the controller 320 outputs a direction control signal for determining the direction of the driving motor 400 and a pulse width modulation signal PWM for controlling the output of the driving motor. Is sent to the gate driver 350.

Accordingly, the gate driver 350 generates a gate signal for turning on one pair of the switches 391 constituting the H-bridge and turning off the other pair, and transmits the gate signal to the H-bridge, thereby driving the motor. 400 may be a forward rotation or a reverse rotation.

On the other hand, the regulator 310 is connected to the battery 500 provided outside the application-specific semiconductor 300, by dropping the voltage supplied from the battery 500, the micro-control unit 200 and the H-bridge The dropped voltage is supplied to the driving motor 400 provided at 390.

In general, when a battery supplies a voltage of 12V to the regulator 310, the regulator 310 supplies a voltage of 2.5V or 5V to the micro control unit 200 and the H-bridge 400.

Meanwhile, the temperature sensor 360, the current sensor 370, and the voltage sensor 380 are provided in the custom semiconductor 300. Each sensor is provided with transmitters 360a, 370a, and 380a for transmitting the sensed values.

In the case of the current sensor 370, it serves to detect the current flowing in the H-bridge 390, and in the case of the voltage sensor 380, the voltage of the battery 500 is directly connected to the battery 500 Or senses a drop voltage output from the regulator 310.

In addition, the temperature sensor 360 serves to detect the temperature of the operating environment of the valve, the actuator, or the pump on which the driving motor 400 is mounted.

The position sensor 4105 detects a current position of the flap or damper.

The error detection unit 340 is connected to the temperature sensor 360, the current sensor 370, the voltage sensor 380, the position sensor 410, the drive motor 400, or the custom semiconductor ( 300) If it is determined that there is an abnormality, and as a result, it is determined that the overvoltage or overcurrent is applied to the drive motor 400 or the application-specific semiconductor 300, the first emergency measures for blocking the introduction of voltage or current is taken.

This is to protect the custom semiconductor 300 and the drive motor 400 from an error situation.

Then, by transmitting the error occurrence situation to the micro control unit 200, the micro control unit 200 and the electronic control unit 100 can act on such an error situation.

Meanwhile, the transmitters 360a, 370a, and 380a of the temperature sensor 360, the current sensor 370, and the voltage sensor 380 are connected to the AD converter 330, and the temperature sensor 360, the The analog signal sensed by the current sensor 370 and the voltage sensor 380 is converted into a digital signal while passing through the AD converter 330 and transmitted to the micro control unit 220.

On the other hand, the position sensor 410 provided outside the on-demand semiconductor 300 to sense the position of the flap or damper, and the temperature sensor 420 installed on the intake or exhaust manifold or pipe, the AD converter 330 and the like. Connected.

Accordingly, the AD converter 330 converts the current value of the analog form output from the temperature sensor 420 or the position sensor 410 into a digital signal and transmits it to the micro control unit 200.

Hereinafter, the control flow of the present invention will be described with reference to FIG. 4.

In order to adjust the amount of fluid such as air supplied to the engine, the opening degree of the flap or the damper of the actuator or the valve must be adjusted, and the target position (target position) of the flap or the damper must be determined to adjust the amount of fluid flow. do.

Therefore, for this purpose, the electronic control unit (ECU) issues a target position command (target position command) for a specific actuator or valve in the direction of the micro control unit (MCU).

The micro control unit MCU transmits a target position to the application specific semiconductor ASIC based on the received command.

Accordingly, in the application specific semiconductor ASIC, the driving motor is operated to match the received target position.

It is determined whether the current driving motor is in an error state during the driving motor operation (S410). Here, the error detection unit (see Fig. 3, 340) determines whether or not the error state.

There are several ways to determine whether there is an error. Specific examples are as follows.

First, the current or voltage supplied to the driving motor is sensed by the voltage sensor or the current sensor, and it is determined whether the current or voltage sensed by the voltage sensor or the current sensor is out of a predetermined range.

On the other hand, it is determined by the position sensor whether the flap or damper opening degree is out of the normal driving range.

Thus, when the error detecting unit determines that the current or voltage sensed by the sensor is out of a predetermined range, or when the opening degree of the flap or damper is determined to be out of the normal driving range, the error information is transmitted to the micro control unit. On the other hand, in order to prevent damage to the system due to an error, the inflow of voltage and current applied to the drive motor is blocked.

Such interruption of voltage and current is preferably achieved through the off state conversion of all switches in the H-bridge to which the driving motor is connected.

On the other hand, the step of determining whether the current sensed by the current sensor is out of a predetermined range consists of determining whether the current flowing in the H-bridge is out of a predetermined range.

Meanwhile, an abnormally open state of the flap or the damper is detected when the output value of the position sensor is out of a predetermined range and recognized by the error detection unit.

In this case, the flap may include transmitting an abnormally open state to the micro control unit.

The determining of the error may include determining whether an input voltage of the battery supplied to the driving motor is out of a predetermined range, and if it is determined that the input voltage of the battery is excessive, the driving motor It is desirable to stop the voltage application to.

In addition, another example of determining the error includes determining whether the voltage output from the regulator is out of a predetermined range, and in this case, it is preferable to stop applying the voltage to the driving motor.

As such, when it is determined that the current state is an error state in which an overcurrent and an overvoltage are applied in the error determination step S410 that includes the above various examples, the error information is transmitted toward the micro control unit (S411).

Then, in step S402, the micro control unit feeds back such error information to the electronic control unit ECU.

In this way, the error information is ultimately transmitted to the electronic control unit ECU, so that a countermeasure for countering such an error can be prepared in the electronic control unit ECU.

Meanwhile, error information is transmitted from the error detection unit, and at the same time or sequentially, the supply of current and voltage is cut off in order to protect the custom semiconductor, the driving motor, or the micro control unit (S412).

Then, after the supply is cut off, the electronic control unit ECU and the micro control unit MCU are in a state of waiting for the next command (S418).

On the other hand, if it is determined in step S410 that there is no error state, the control step is performed by the controller (S413).

In performing the normal control step, the input value of the controller is a difference between the target position value and the actual position value of the flap or damper as described above, and the controller minimizes the difference so that the position of the flap or damper is the target position value. Perform the control function to have.

The controller is preferably provided with a PID controller as described above, and optimizes the control of the drive motor according to the situation by changing various control parameters.

Then, the H-bridge is driven, so that the forward or reverse rotation of the motor can be made (S414). In other words, when any one of the four switches is turned on and the other pair is turned off, forward rotation may occur, and in reverse, reverse rotation occurs.

Through this reverse rotation and forward rotation, the opening degree of the flap, damper, or rod can be adjusted.

On the other hand, the position sensor checks the position value of the flap, damper, or load state (S415), and the position information is converted into a digital signal through the AD converter and then the micro control unit (MCU) Is delivered.

In addition, the positional information transmitted to the micro control unit MCU is fed back to the electronic control unit ECU to become basic information for controlling the driving motor in the future (S403).

After step S416, it is determined whether or not the target position has been reached (S417). If not, the driving motor is re-operated by control by the controller, and when the target position is reached, the next step is reached. The standby state is maintained until a command is received (S418).
