Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In a first embodiment of the method for controlling powering on of the equipment mounted on the motor home, referring to fig. 1, the method is applied to a vehicle control unit, and the method for controlling powering on of the equipment mounted on the motor home includes:
step S10, detecting whether a power-on request is received from the upper-mounted device.
In this embodiment, the upper-mounted device is a high-voltage electric device installed on a motor home, and includes an air conditioner, a television, a refrigerator, a water heater, and the like.
The power-on request device of the upper equipment CAN be a key switch or a voice recording device (microphone), the power-on request device of the upper equipment is connected with the whole vehicle Controller through a wire harness or a CAN Network (Controller Area Network), and the power-on request device of the upper equipment CAN be arranged on a control panel of a cab or a control panel of a car as a house.
If the power-on request device of the upper equipment is a key switch, when the key switch is pressed down, the vehicle control unit connected with the key switch receives a high potential output by the key switch, so that the vehicle control unit receives a power-on request of the upper equipment; on the contrary, when the key switch is not pressed down, the vehicle control unit connected with the key switch receives the low potential output by the key switch, so that the vehicle control unit does not receive the power-on request of the upper equipment.
If the power-on request device of the loading equipment is a voice recording device, the vehicle control unit receives voice information recorded and sent by the voice recording device, identifies the voice information, judges whether the voice information is a power-on request of the loading equipment, and receives the power-on request of the loading equipment if the voice information is the power-on request of the loading equipment; if the voice information is not the power-on request of the upper-mounted equipment, the vehicle control unit does not receive the power-on request of the upper-mounted equipment. The voice information recorded by the voice recording apparatus may be mandarin or dialect.
The step of identifying the voice information and judging whether the voice information is a power-on request of the upper device may be:
constructing a voice recognition acoustic preset model;
training the voice recognition acoustic preset model to obtain a voice acoustic model;
inputting the voice information into the voice acoustic model, and outputting to obtain a voice text;
traversing each associated character in the associated characters, and executing the step of judging whether the associated character exists in the long character string to obtain a plurality of judgment results;
combining the multiple judgment results to obtain an actual measurement vector;
and calculating the distance between the measured vector and a preset vector to obtain the similarity of the key file.
Note that, in this embodiment, the speech recognition acoustic model may be a Hidden Markov Model (HMM); the plurality of associated characters are 'load', 'device' and 'power on'; the number of elements in the predetermined vector is the same as the number of elements in the actual measurement vector, and each element in the predetermined vector is 1, for example, when the actual measurement vector is a ═ 1,0,1, the predetermined vector is b ═ 1,0,1, and the distance between the actual measurement vector and the predetermined vector can be any one of a manhattan distance, an euclidean distance, a chebyshev distance, and a minkowski distance.
In step S20, if yes, it is detected whether an ignition signal is received from the ignition switch.
In this embodiment, the ignition switch is connected to the vehicle controller through the wire harness or the CAN network, when the ignition switch is activated, a signal corresponding to the activation of the ignition switch is transmitted to the vehicle controller through the wire harness or the CAN network, and the vehicle controller detects the received ignition switch signal to determine whether the ignition switch signal is an OFF signal, an ON signal, or a READY signal.
In addition, in step S20 of the present embodiment, if the power-on request from the mounted device is not received, it is periodically or continuously detected whether the power-on request from the mounted device is received.
And step S30, if the ignition switch signal is not detected or is detected to be an OFF signal, controlling the motor home to enter a single power-on mode of the upper-mounted equipment.
It should be noted that, in this embodiment, when the ignition switch information is not detected or the detected ignition switch signal is an OFF signal, it indicates that the recreational vehicle is now in the parking state, and therefore the recreational vehicle is controlled to enter the single power-on mode of the upper-mounted device. In the power system of the motor home, after the motor controller and the brake controller receive the enabling instruction of the vehicle control unit, the vehicle control unit can only receive the signals returned by the motor, the brake pedal, the hand brake and the like, so that the motor home is controlled to enter the single power-on mode of the upper equipment.
The first method is as follows: controlling a main relay in the high-voltage controller to be closed, and controlling a power battery to supply power to a low-voltage electric device so as to electrify at low voltage; and sending a high-voltage power-on instruction of the upper equipment to the high-voltage controller so as to carry out high-voltage power-on.
The second method comprises the following steps: controlling a main relay in the high-voltage controller to be closed, and controlling a power battery to supply power to a low-voltage electric device so as to electrify at low voltage; and sending a high-voltage power-on command to the high-voltage controller, and not sending an enabling command to the motor controller and the brake controller so as to carry out high-voltage power-on.
It should be noted that, in this embodiment, the high-voltage controller may perform high-voltage distribution, where the first path is distributed to the upper equipment, the second path is distributed to the power system, and the third path is distributed to the low-voltage electric devices, where the low-voltage electric devices include a vehicle controller, a control panel, a motor controller, a brake controller, and the like. The high-voltage controller comprises a main relay, a first relay corresponding to the upper equipment and a second relay corresponding to the power system, wherein the main relay is electrically connected with the power battery, the first relay is electrically connected with the upper DC/DC module and/or the upper DC/AC module, the second relay is electrically connected with a driving motor in the power system, the main relay is also electrically connected with the chassis DC/DC module, and the chassis DC/DC module is electrically connected with the low-voltage electric appliance.
In the first mode, a main relay in a high-voltage controller is controlled to be closed, and a power battery supplies power to low-voltage electric appliances through a chassis DC/DC module to realize low-voltage electrification; and then sending a high-voltage electrifying instruction of the upper equipment to the high-voltage controller, controlling a first relay in the high-voltage controller to be closed, and supplying power to the upper equipment by the power battery through the upper DC/DC module and/or the upper DC/AC module to realize high-voltage electrifying. Because the power system power-on instruction is not sent to the high-voltage controller, a second relay in the high-voltage controller is not closed, a driving motor in the power system does not work, the motor home is in a parking state, and the upper equipment independently uses electricity.
In the second mode, the main relay in the high-voltage controller is controlled to be closed, and the power battery supplies power to low-voltage electric appliances through the chassis DC/DC module to realize low-voltage electrification; and then sending a high-voltage power-on instruction to the high-voltage controller to control the closing of a first relay and a second relay in the high-voltage controller, supplying power to a device by a power battery through an upper DC/DC module and/or an upper DC/AC module, supplying power to a driving motor by the power battery to realize high-voltage power-on, but not sending an enabling instruction to the motor controller and the brake controller, wherein the whole vehicle controller cannot perform signal feedback on signals such as a motor, a brake pedal and a hand brake, the state of the whole vehicle is equal to the parking state, and the upper device independently uses power.
And step S40, if the ignition signal is detected and is an ON signal or a READY signal, controlling the motor home to enter a standard power-ON mode.
It should be noted that, in this embodiment, when the ignition switch signal is detected to be the ON signal or the READY signal, it indicates that the motor home is now in the starting state, so that the motor home is controlled to enter the standard power-ON mode.
The step of controlling the motor home to enter the standard power-on mode comprises the following steps:
controlling a main relay in the high-voltage controller to be closed, and controlling a power battery to supply power to a low-voltage electric device so as to electrify at low voltage;
and sending a high-voltage power-on command to the high-voltage controller, and sending an enabling command to the motor controller and the brake controller to carry out high-voltage power-on.
The power battery supplies power for low-voltage electric appliances through a chassis DC/DC module to realize low-voltage electrification; and then sending a high-voltage electrifying instruction to the high-voltage controller, controlling a first relay and a second relay in the high-voltage controller to be closed, supplying power to a power battery through an upper DC/DC module and/or an upper DC/AC module, supplying power to a driving motor by the power battery, realizing high-voltage electrifying, sending enabling instructions to the motor controller and the brake controller, receiving signals of the motor, a brake pedal, a hand brake and the like by the whole vehicle controller, feeding back the signals, and realizing a standard electrifying mode by the motor house.
Compared with the prior art that the home equipment needs to be used in the starting state of the whole car, the situation of safety accidents caused by mistaken touch of switches such as a hand brake and the like can occur, and further the safety of the independent power utilization of the home equipment is reduced, the home equipment power utilization method has the advantages that whether the power-on request from the home equipment is received or not is detected; if yes, detecting whether an ignition signal from an ignition switch is received; if the ignition signal is not detected or the detected ignition signal is an OFF signal, controlling the caravan to enter a single power-on mode of the upper equipment; if the ignition signal is detected and is an ON signal or a READY signal, the motor home is controlled to enter a standard power-ON mode, namely, the power supply to the upper equipment and the power supply to the power system are divided into two branches in the application, and when the upper equipment is independently powered, the power system is not powered, so that the upper equipment cannot touch switches such as a hand brake and the like during independent power utilization, the safety accident is caused, and the safety of the independent power utilization of the upper equipment is further improved. Meanwhile, when the person leaves the motor home for a short time, the motor home can be powered off to lock the motor home, and the upper equipment such as a washing machine, a refrigerator and the like can still work normally.
Based ON the foregoing first embodiment, a second embodiment of the power-ON control method for the ON-board device of the caravan of the present application is provided, and with reference to fig. 2, if the ignition signal is detected, and after the step of detecting the ignition signal as an ON signal or a READY signal, the method further includes the following steps:
and step A10, starting timing, and detecting the bearing capacity of the driver seat.
It should be noted that, in this embodiment, a pressure sensor is arranged on the driver seat, the pressure sensor is connected to the vehicle controller through a wire harness or a CAN network, and the pressure sensor CAN send the detected load bearing capacity on the driver seat to the vehicle controller.

The process of determining whether there is a power-down request of the power-on device is the same as the process of determining whether there is a power-on request of the power-on device, and is not described herein again. The single power-on mode and the standard power-on mode of the upper equipment can be switched under the condition of meeting the conditions, so that the use convenience of the power consumption of the upper equipment is improved.
