Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the vehicle control device, the method and the vehicle provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The application scenario may include a vehicle provided with a vehicle control device. The vehicle may be an automobile driven by a motor (e.g., a pure electric vehicle or a hybrid electric vehicle), or may be another motor vehicle or a non-motor vehicle driven by a motor.
Fig. 1 is a block diagram illustrating a vehicle control apparatus according to an exemplary embodiment. As shown in fig. 1, the apparatus 100 includes: the air compressor comprises an air compressor 101, a motor 102, a steering vane pump 103, a motor controller 104, a low-voltage controller 105 and an electromagnetic valve 106, wherein the motor controller 104 is respectively connected with a power battery 200 and the motor 102 of a vehicle, the motor 102 is respectively mechanically connected with the air compressor 101 and the steering vane pump 103, the electromagnetic valve 106 is mechanically connected with the air compressor 101, and the low-voltage controller 105 is connected with the electromagnetic valve 106. The motor controller 104 may be a DC/AC controller, among others.
The motor controller 104 is configured to convert the high-voltage dc output by the power battery 200 into ac power to power the motor 102 when receiving an enable signal sent by a VCU (Vehicle Control Unit, chinese) 300.
And the steering vane pump 103 is used for providing steering assistance for the vehicle after the motor 102 is powered on.
For example, the light weight and integration of the whole vehicle become one of the main trends of the current vehicle development, in order to simplify the parts of the whole vehicle, reduce the cost, save the space of the whole vehicle and reduce the weight of the whole vehicle, the air compressor 101 and the steering vane pump 103 can be connected with the motor 102 in a mechanical connection mode, and the air compressor 101 and the steering vane pump 103 are controlled by the motor controller 104, that is, only one motor 102 and one motor controller 104 are needed to realize the functions of the air compressor and the power steering pump at the same time, and independent motors and DC/AC controllers do not need to be configured for the air compressor 101 and the steering vane pump 103 respectively. In the process of running the whole vehicle, in order to ensure safety, the motor 102 needs to be in a working state all the time to ensure that the steering vane pump 103 works uninterruptedly, so that steering assistance is continuously provided for the vehicle. Therefore, when the vehicle is powered on or running, the VCU 300 may send an enable signal to the motor controller 104, and the motor controller 104 may convert the high-voltage dc output by the power battery 200 into three-phase ac after receiving the enable signal to power the motor 102. After the motor 102 is powered on, the motor 102 enters a working state and operates according to a preset rotating speed to drive the steering vane pump 103, so that the steering vane pump 103 provides steering assistance for the vehicle, and a user is assisted in controlling the steering of the vehicle.
And the low-voltage controller 105 is used for acquiring a pressure signal after the motor 102 is powered on, and controlling the electromagnetic valve 106 to be opened or closed according to the pressure signal, wherein the pressure signal is used for indicating the pressure in an air storage cylinder of the vehicle.
The air compressor 101 is configured to inflate the air cylinder when the solenoid valve 106 is closed, and to stop the inflation of the air cylinder when the solenoid valve 106 is opened.
For example, after the motor 102 is powered on, the motor 102 will drive the air compressor 101 to compress the air into a gas with a certain pressure, and the gas is stored in the air storage cylinder of the vehicle. When the gas of gas receiver storage is sufficient, can regard as the air supply by the gas receiver to use when supplying brake braking and switch door, when the gas of gas receiver storage is not enough, need aerify to the gas receiver through air compressor machine 101. Therefore, the air compressor 101 can work intermittently (i.e., the air cylinder is inflated by intermittently controlling the air compressor 101), so that the energy saving of the whole vehicle is realized. For example, a low pressure controller 105 and a solenoid valve 106 may be provided in the vehicle control device 100, and whether the air compressor 101 inflates the air tank may be controlled by opening or closing the solenoid valve 106. After the motor 102 is powered on, a pressure signal indicating the pressure in the air reservoir of the vehicle is acquired by the low-pressure controller 105, and the solenoid valve 106 is controlled to open or close according to the pressure signal. When the pressure signal indicates that the pressure in the air reservoir is low (i.e. when the air reservoir stores insufficient gas), the solenoid valve 106 is controlled to be closed by the low-pressure controller 105, and when the pressure signal indicates that the pressure in the air reservoir is high (i.e. when the air reservoir stores sufficient gas), the solenoid valve 106 is controlled to be opened by the low-pressure controller 105. When the solenoid valve 106 is closed, the air cylinder is inflated by the air compressor 101, and the air compressor 101 is in a load state (the energy consumption of the air compressor 101 is high in the load state). When the electromagnetic valve 106 is opened, the air compressor 101 is driven by the motor 102 to perform internal circulation to stop charging the air cylinder, and at this time, the air compressor 101 is in an idling state (the energy consumption of the air compressor 101 is low in the idling state). By circulating the air compressor 101 in the no-load state and the load state, the air compressor 101 is prevented from being always in the load state, and the energy consumption of the vehicle is reduced.
It should be noted that the mechanical connection described in the above embodiments may be, for example, a connection through a transmission device, or may be a connection through a customized mechanical component, which is not limited in the present disclosure.
In summary, the vehicle control device in the present disclosure includes: the system comprises an air compressor, a motor, a steering vane pump, a motor controller, a low-voltage controller and an electromagnetic valve, wherein the motor controller is respectively connected with a power battery and a motor of a vehicle, the motor is respectively mechanically connected with the air compressor and the steering vane pump, the electromagnetic valve is mechanically connected with the air compressor, and the low-voltage controller is connected with the electromagnetic valve. The vehicle-mounted steering system comprises a motor controller, a steering vane pump, a low-voltage controller and an air compressor, wherein the motor controller is used for converting high-voltage direct current output by a power battery into alternating current when receiving an enabling signal sent by a VCU of a vehicle controller, and the alternating current is used for powering on the motor. This openly can control the air compressor machine simultaneously through machine controller and turn to the impeller pump, make whole car lightweight and integrated degree high, with low costs to can also aerify to the gas receiver according to pressure signal control air compressor machine, reduce the energy consumption of vehicle.
Fig. 2 is a block diagram illustrating another vehicle control apparatus according to an exemplary embodiment. As shown in fig. 2, the apparatus 100 further includes: a rocker switch 107, the rocker switch 107 being connected to the motor controller 104.
And the motor controller 104 is used for acquiring a switch signal sent by the rocker switch 107.
And the motor controller 104 is configured to convert the high-voltage direct current output by the power battery 200 into alternating current to power on the motor 102 when the enable signal is received and the switch signal indicates that the rocker switch 107 is in a closed state.
And the motor controller 104 is configured to stop converting the high-voltage direct current output by the power battery 200 into alternating current to power down the motor 102 when the enable signal is received and the switch signal indicates that the rocker switch 107 is in an open state.
In another implementation scenario, when there is no driving demand, the user may control whether to activate the steering vane pump 103 to provide steering assistance to the vehicle via the rocker switch 107 in the vehicle control device 100 to avoid unnecessary power consumption. For example, when a user needs to drive, that is, when the steering vane pump 103 needs to provide the steering assistance, the rocker switch 107 may be switched to the closed state, the rocker switch 107 sends a switch signal (the switch signal may be a level signal, for example) indicating that the rocker switch 107 is in the closed state, when the user does not need to provide the steering assistance for the steering vane pump 103, the rocker switch 107 may be switched to the open state, the rocker switch 107 sends a switch signal indicating that the rocker switch 107 is in the open state, for example, when the switch signal is at a high level, the rocker switch 107 is indicated to be in the closed state, and when the switch signal is at a low level, the rocker switch 107 is indicated to be in the open state. Then, a switch signal sent by the rocker switch 107 is obtained through the motor controller 104, and when the motor controller 104 receives the enable signal and the switch signal indicates that the rocker switch 107 is in a closed state, the high-voltage direct current output by the power battery 200 is converted into a three-phase alternating current to power the motor 102. When the enable signal is received and the switch signal indicates that the rocker switch 107 is in the on state, the motor controller 104 stops converting the high-voltage direct current output by the power battery 200 into the three-phase alternating current to power down the motor 102.
Fig. 3 is a block diagram illustrating another vehicle control apparatus according to an exemplary embodiment. As shown in fig. 3, the apparatus 100 further includes: and a pressure switch 108, wherein the pressure switch 108 is connected with the low-pressure controller 105.
And the low-voltage controller 105 is used for acquiring a pressure signal sent by the pressure switch 108 after the motor 102 is powered on.
A low pressure controller 105 for controlling the solenoid valve 106 to close when the pressure signal indicates that the pressure in the air reservoir is below a preset pressure threshold.
A low pressure controller 105 for controlling the solenoid valve 106 to open when the pressure signal indicates that the pressure in the air reservoir is above a preset pressure threshold.
For example, the vehicle control device 100 is pre-provided with a pressure switch 108, and the pressure switch 108 may be disposed in or near the air reservoir to monitor the pressure in the air reservoir. The pressure switch 108 is capable of outputting a pressure signal indicating that the pressure in the air reservoir is lower than a preset pressure threshold when the pressure in the air reservoir is lower than the preset pressure threshold, and outputting a pressure signal indicating that the pressure in the air reservoir is higher than the preset pressure threshold when the pressure in the air reservoir is higher than the preset pressure threshold. The pressure signal may be a level signal, for example, when the pressure signal is at a high level, the pressure signal indicates that the pressure in the air reservoir is higher than a preset pressure threshold, and when the pressure signal is at a low level, the pressure signal indicates that the pressure in the air reservoir is lower than the preset pressure threshold. After the motor 102 is powered on, a pressure signal sent by the pressure switch 108 is acquired through the low-pressure controller 105, and when the pressure signal acquired by the low-pressure controller 105 indicates that the pressure in the air reservoir is lower than a preset pressure threshold value, the electromagnetic valve 106 is controlled to be closed, and the air reservoir is inflated through the air compressor 101. When the pressure signal obtained by the low pressure controller 105 indicates that the pressure in the air reservoir is higher than the preset pressure threshold, the solenoid valve 106 is controlled to open, and the air reservoir is stopped from being inflated by the air compressor 101.
Fig. 4 is a block diagram illustrating yet another vehicle control apparatus according to an exemplary embodiment. As shown in fig. 4, the apparatus 100 further includes a temperature sensor 109, and the temperature sensor 109 is mechanically connected to the air compressor.
And the temperature sensor 109 is used for acquiring the temperature of the air compressor 101 and sending an alarm signal to the low-pressure controller 105 when the temperature is greater than or equal to the first temperature threshold and is less than the second temperature threshold.
And the temperature sensor 109 is further configured to send an abnormal signal to the low-voltage controller 105 when the temperature is greater than or equal to a second temperature threshold, where the second temperature threshold is greater than the first temperature threshold.
In one scenario, if the air compressor 101 works for a long time, the temperature of the air compressor 101 may rise, and when the temperature of the air compressor 101 is too high, the air compressor 101 may be damaged or even threatened to drive safety. In order to improve the safety of the vehicle, a temperature sensor 109 may be mounted on the head of the air compressor 101. The temperature of the air compressor 101 is acquired by the temperature sensor 109, and when the acquired temperature of the air compressor 101 is greater than or equal to a first temperature threshold value and less than a second temperature threshold value, the temperature sensor 109 sends an alarm signal to the low-pressure controller 105. The temperature sensor 109 sends an abnormality signal to the low pressure controller 105 when the acquired temperature of the air compressor 101 is greater than or equal to the second temperature threshold value.
Further, the low voltage controller 105, upon receiving the alarm signal, issues an alarm signal to alert the user. The manner of sending out the warning signal by the low voltage controller 105 may be, for example, playing a preset voice prompt continuously and cyclically through a broadcasting system of the vehicle, or controlling a warning lamp of the vehicle to flash in a preset manner (for example, controlling a vehicle lamp to flash at a preset frequency), or displaying the warning signal in an image manner on a display screen or an instrument panel of the vehicle.
The low voltage controller 105 may forcibly stop the power supply of the solenoid valve 106 to supply power to the solenoid valve 106 upon receiving the abnormality signal, thereby controlling the solenoid valve 106 to be opened to stop the air compressor 101 from inflating the air cylinder. When the temperature of the air compressor 101 acquired by the temperature sensor 109 is reduced below the first temperature threshold, the temperature sensor 109 may send a restart signal to the low-voltage controller 105, and after the low-voltage controller 105 receives the restart signal, the low-voltage controller controls the power supply of the magnetic valve 106 to resume supplying power to the electromagnetic valve 106, so that the air compressor 101 resumes operating, thereby ensuring that the air compressor 101 can safely operate.
