The vehicle control unit is used for receiving the electric signal detected by the storage battery sensor and performing action according to the electric signal. And under the condition that the electric signal acquired by the storage battery sensor meets the circuit disconnection condition, disconnecting the whole vehicle circuit from the control switch. The circuit disconnection condition may be that the electrical signal exceeds a certain threshold, or that the change rate of the electrical signal exceeds a certain threshold, or other performance parameters that may indicate that the electric quantity of the battery is lower than a safety threshold. For example, the battery sensor detects a voltage signal of the battery, and the vehicle controller controls the vehicle circuit to be powered off when the voltage signal is lower than a voltage safety threshold of the battery. The vehicle control unit can be powered by the storage battery.
As an alternative embodiment, the switch is a relay. The switch is used for receiving a disconnection signal of the vehicle control unit to act and disconnect the circuit.

When the voltage signal is lower than the cut-off voltage threshold, the switch is directly controlled to cut off the whole vehicle circuit, however, when the whole vehicle circuit is cut off, a user is using the vehicle equipment, the whole vehicle circuit is suddenly cut off, the vehicle owner experience may be affected, the vehicle owner misunderstanding may be caused, and the vehicle owner misunderstanding is taken as a vehicle fault, so that one or more first voltage thresholds used for prompting the low voltage of the storage battery are arranged above the cut-off voltage threshold. When the voltage of the battery detected by the battery sensor is lower than a first voltage threshold, a prompt message is sent to a predetermined object. For example, a warning tone is played through a sound, or a warning text is played through a display screen.

In addition, when the prompt message is possibly transmitted, if the owner is not in the vehicle, the user may not receive the prompt message, so that the purpose of transmitting the prompt message to the owner who is not in the vehicle is achieved by the signal transmitter to the vehicle key or the mobile terminal bound by the vehicle.
As an alternative embodiment, the start-up condition includes at least one of: for example, whether a door of the vehicle is locked, whether a trunk is locked, and whether a tank door is locked; whether a gear of the vehicle is in a neutral position; whether a hand brake of the vehicle is turned on; whether the fuel of the vehicle is greater than a predetermined fuel. The vehicle starting conditions are many, whether the door of the vehicle is locked or not is detected, and the condition that a driver mistakenly triggers to start the vehicle to cause a safety accident due to the fact that a person is getting on or off the vehicle is prevented; detecting whether the trunk is locked or not, and preventing the trunk from being obtained and lost; the fuel tank door prevents a vehicle from being started without pulling the fuel gun in the fuel filling process, so that safety accidents are caused; whether the gear is in a neutral position or not is detected, and the situation that the engine is flamed out due to overhigh rotating speed of the engine required by starting the vehicle is prevented; whether the hand brake is started or not is detected, and the hand brake and the vehicle are prevented from being damaged; and detecting whether the fuel is sufficient or not to ensure the driving mileage of the vehicle.

The activation signal may include a charge threshold of the battery, and the engine is automatically controlled to shut down when the voltage in the battery rises above the charge threshold. The higher the charging threshold value is, the higher the electric quantity of the storage battery is, the longer the required working time of the engine is, and the more energy is consumed; the lower the charge of the battery, the shorter the time it takes to support the operation of the vehicle. Therefore, the user is required to set the charging threshold according to specific requirements. Whether the vehicle is in the state of waiting to start or not is detected, and under the condition that the vehicle is not in the state of waiting to start, the vehicle owner is not in the vehicle, and the vehicle can not start in a short time.

If the vehicle owner knows that the battery is not charged when the vehicle owner receives the engine start signal within the predetermined time, the vehicle owner may return to the vehicle and prepare to manually start the vehicle if the vehicle owner does not choose to charge the battery. At this time, after the vehicle owner manually starts the vehicle, the electric quantity of the storage battery cannot be instantaneously higher than the first voltage threshold, so that the automatic power off is caused again, and the vehicle owner cannot manually start the vehicle. Therefore, under the condition that an engine starting signal is not received within a preset time period, whether the voltage is lower than a second voltage threshold value or not is detected, under the condition that the voltage is lower than the second voltage threshold value, whether a key of the vehicle is inserted into a key ring or whether a key of the vehicle is in the vehicle is detected, under the condition that the key is not inserted into the key ring and the key is not in the vehicle is detected, a circuit for disconnecting the storage battery to supply power to the electronic equipment is sent to the switch, and whether the vehicle owner is in the vehicle or not is judged by detecting whether the key of the vehicle is inserted into the key ring or whether the key of the vehicle is in the vehicle.
It should be noted that the present embodiment further provides a vehicle power management device controlled remotely, and as a preferred embodiment of the present embodiment, the preferred embodiment is described in detail below.
The purpose of the preferred embodiment is to provide a vehicle power management device capable of being remotely controlled, which is realized by a remote control key or a mobile phone, a storage battery, a sensor, a relay, a CAN bus combined with a vehicle, a controller and a telematics T-BOX (telematics BOX).
In the preferred embodiment, the storage battery voltage sensor and the manual disconnection/reset relay are additionally arranged, the control logic is additionally arranged in the vehicle control unit, the T-BOX self function is combined, the information receiving and sending function is additionally arranged in the key, meanwhile, the mobile phone can be combined to receive and send information, when the vehicle is flamed out and parked, the storage battery voltage is monitored in real time, and the vehicle power management system capable of being remotely controlled is realized.
The specific implementation of this preferred embodiment is as follows:
the system comprises a storage battery voltage sensor, a manual disconnection/reset relay, a T-BOX and a client APP.
Firstly, a storage battery voltage monitoring part;
when the electric quantity of the storage battery is consumed, the voltage also can be reduced, a voltage sensor is additionally arranged on the storage battery, and when a vehicle is flamed out, voltage signals of the storage battery are collected in real time and transmitted to the vehicle control unit.
Secondly, a whole vehicle circuit part;
usually, when a circuit of a whole vehicle is designed, a main circuit of a positive electrode and a negative electrode of a storage battery is a key for switching on and off the circuit of the whole vehicle. The on-off of the main power supply of the whole vehicle is realized by connecting a relay which can be manually disconnected/reset in series with the main circuit of the storage battery. The relay has the function that the controller can control the disconnection of the relay and can be manually disconnected and reset at the same time.
1) When the vehicle needs to be parked for a long time and used again, a vehicle owner can manually realize the disconnection and the connection of the whole vehicle circuit through a relay connected in series with the main circuit of the storage battery.
2) When the main power supply of the whole vehicle is not cut off by a vehicle owner, the controller can execute the control of the relay to cut off the circuit of the whole vehicle according to the judgment of the voltage of the storage battery when the voltage is lower than a set value.
3) When the main circuit power supply of the vehicle is cut off, the controller can not play a role to control the relay any more, and the connection of the main circuit power supply of the whole vehicle can be realized only by manually operating the reset of the relay.
Thirdly, calculating a control part;
the calculation control part is realized by the vehicle control unit, analyzes and processes the acquired information, and outputs a control instruction through a calculation flow. Fig. 2 is a flowchart of a battery management method according to a preferred embodiment of the present invention, and as shown in fig. 2, the calculation process is mainly divided into the following steps:
1) detecting whether the engine runs or not, and if the engine stops, the electric quantity of the storage battery is in a consumption state; if the engine runs, returning to the detection state;
2) detecting the voltage of the storage battery, and judging whether the voltage is lower than a first set value U1If it is lower than U1And then sending a prompt signal to the key of the vehicle owner to prompt that the voltage of the storage battery is low. The reminding time period is T. If not, continuing to return to the detection state;
3) whether an engine starting signal is received or not is detected, the starting signal is received, whether a vehicle door, a trunk and an oil tank door are locked or not is detected, whether a gear is in a neutral gear or not is detected, whether a hand brake is opened or not is detected, whether fuel oil is larger than F or not is detected, the engine is controlled to be started to charge a storage battery only if all four conditions are yes, and if any condition is not, a relay is controlled to cut off a power supply of the whole vehicle. After the engine is started, the voltage of the storage battery is continuously detected, and after the voltage reaches a rated voltage U, the engine is controlled to stop running and continuously returns to the detection state of 1;
if the starting signal is not received, whether the voltage of the storage battery is lower than a set value U or not is judged2The voltage of the storage battery is not lower than a set value U2Then, the detection state of 1 is continuously returned; is lower than the set value U2If yes, returning to the detection state of 1; if not, the main circuit relay of the storage battery is controlled to be disconnected, and the power supply of the whole vehicle is cut off (the whole vehicle controller stops working at the same time).
Whether a car door, a trunk and an oil tank door are locked or not is acquired from the controller, a gear signal is acquired from a neutral switch, a parking brake signal is acquired from a hand brake switch or an EPB (electric brake panel), and a fuel surplus signal is acquired from a whole car instrument.
It should be noted that if there is no logical judgment of "whether the key is inserted into the key hole/in the vehicle", then when the battery is below U2Then, if the relay is manually reset by the owner, the controller can cut off the power supply of the storage battery again, so that the owner cannot start the vehicle. With the logical judgment, when the key is inserted into the key hole or in the vehicle, the vehicle owner can be in the state that the storage battery is lower than U2And manually resetting the relay and then starting the vehicle.
Fourthly, the vehicle owner receives the prompt signal and sends an instruction part;
the vehicle owner receives the prompt signal and sends the instruction part in two ways.
The first method is as follows: receiving and transmitting by using a key;
the integrated signal receiving and sending function is realized on an automobile key, the SIM card is used for realizing network communication, and a button for remotely starting an engine is added on the key. After the key receives the battery voltage low signal sent by the T-BOX of the vehicle, an indicator lamp on the key is lightened to prompt the owner of the vehicle. If the owner needs to start the transmitter to charge the storage battery and presses a remote start engine button on the key, a signal can be sent to the vehicle T-BOX through a communication network, the T-BOX outputs an instruction to the vehicle controller, and the vehicle controller executes the start of the engine.
The second method comprises the following steps: receiving and sending through a mobile phone;
the T-BOX can transmit the low signal of the storage battery voltage to the mobile phone of the owner in the form of information. If the owner needs to start the engine to charge the storage battery, the corresponding application program of the mobile phone is logged in, the signal is sent to the T-BOX of the vehicle, the T-BOX outputs an instruction to the vehicle control unit, and the controller executes the starting of the engine.
In summary, the preferred embodiment is based on the vehicle control unit, the T-BOX and the communication network, and has a simple implementation and strong versatility.
