[0036] In order to better understand the above-mentioned technical scheme, the above-mentioned technical scheme will be described in detail below in combination with the accompanying drawings and specific implementation methods of the specification. It should be understood that the embodiments of the present disclosure and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0037] Figure 1 is a circuit diagram of a vehicle safety on / off power control system provided by an embodiment of the present invention, such as Figure 1 As shown, the safety on-off power control system includes a power supply module 10 , a safety on-off module 20 and a control module 30 .

[0038] The power supply module 10 includes a main power supply 11 and a backup power supply 12, which are used to supply power to the vehicle's additional equipment 100a. The safety on-off module 20 includes a main power supply circuit 20a arranged between the main power supply 11 and the additional equipment 100a, and a backup power supply circuit 20b arranged between the backup power supply 12 and the additional equipment 100a, and an on-off switch 21 is provided on the main power supply circuit 20a. The control module 30 is electrically connected to the power supply module 10 and the safety on-off module 20, and is used to control the on-off of the on-off switch 21, and the working states of the main power supply 11 and the backup power supply 12 when the vehicle is in different working modes, so that at least one of the main power supply 11 and the backup power supply 12 supplies power to the additional equipment 100a, or stops supplying power to the additional equipment 100a.

[0039] It should be noted that the safe on-off power control system provided in this embodiment is suitable for extended-range vehicles for special purposes, and the installed equipment may be high-power electrical equipment such as power lighting, hydraulic equipment, and medical equipment.

[0040] Optionally, the main power supply 11 is a DC converter (DCDC), and the backup power supply 12 is a backup generator. The DC converter can convert the high-voltage DC power output by the vehicle power battery into the low-voltage DC power required by the installed equipment. This conversion process is efficient and stable, and can ensure that the installed equipment obtains a stable power supply. At the same time, different installed equipment may have different requirements for voltage and current. The DC converter can be customized or adjusted according to specific needs to meet the power supply requirements of different installed equipment. As a supplement to the main power supply, the backup generator can supply power to the installed equipment when the DC converter fails or cannot meet the power supply demand, so as to meet the power supply demand of high-power installed equipment.

[0041] Specifically, Figure 1As shown, the output end of the DC converter is electrically connected to one end of the on-off switch 21, and the other end of the on-off switch 21 is electrically connected to the additional equipment to form a main power supply circuit 20a, wherein there are multiple additional equipment 100a, and the other end of the on-off switch 21 is electrically connected to multiple additional equipment 100a respectively. The output end of the standby generator is connected to the other end of the on-off switch 21, thereby being electrically connected to multiple additional equipment 100a to form a standby power supply circuit 20b. The standby generator and the DC converter are equivalent to a parallel relationship. When the standby generator and the DC converter work at the same time, the current in the circuit can be increased, thereby meeting the power supply requirements of high-power additional equipment.

[0042] Optionally, the on-off switch 21 is a relay, which can isolate the circuit and avoid direct connection between the main power supply 11 and the installed device 100a, thereby reducing mutual interference between circuits and potential damage risks. The relay has the advantages of long life, strong impact resistance, and not easy to damage.

[0043] In this embodiment, the working mode of the vehicle includes at least a normal mode, a high-speed mode and a slow mode. Among them, the normal mode refers to the mode in which the vehicle is driving normally, the high-speed mode refers to the mode in which the vehicle is driving at a high speed (i.e., the vehicle speed is greater than the maximum vehicle speed threshold, which is usually the best driving speed that a car can achieve on a level and good road surface and can be obtained by calibration), and the slow mode refers to the mode in which the vehicle is driving slowly (i.e., the vehicle speed is less than the minimum vehicle speed threshold, and the specific range of the minimum vehicle speed threshold will vary according to different gears and vehicle designs. For example, the minimum vehicle speed threshold corresponding to the first gear may be 0-5km / h, which is suitable for starting or climbing and other occasions that require large torque).

[0044] Optionally, the control module 30 is used to:

[0045] When the vehicle is in normal mode, the on-off switch is controlled to be connected, and the main power supply is controlled to work to supply power to the added equipment; when the output power of the main power supply exceeds the set power threshold, the backup power supply is controlled to work and supply power to the added equipment at the same time as the main power supply; when the vehicle is in high-speed mode, the on-off switch is controlled to be disconnected, and the backup power supply is controlled to shut down and stop supplying power to the added equipment; when the vehicle is in slow mode, the on-off switch is controlled to be connected, and the main power supply and the backup power supply are controlled to supply power to the added equipment at the same time under full power state.

[0046] In the above implementation, when the vehicle is in normal mode, the DC converter needs to supply power to the vehicle's own electrical equipment, and when the on-off switch is connected, the DC converter also needs to supply power to the additional equipment. At this time, the control module 30 needs to detect the output power of the DC converter. If the output power of the DC converter exceeds the set power threshold (for example, 90% of the rated output power of the DC converter), the control module 30 will control the standby generator to start working, and supply power to the additional equipment 100a together with the DC converter to improve the power supply reliability and prevent the DC converter from overloading, thereby causing the electrical components to overheat and burn, seriously affecting the stability and safety of the vehicle's electrical system. When the vehicle is in the extreme speed mode, the vehicle's power and power systems are often in a high-load state, and any unnecessary power consumption may have an adverse effect on the performance and safety of the vehicle. At this time, the control module 30 controls the on-off switch to be disconnected, and controls the standby power supply to be shut down, and stops supplying power to the installed equipment 100a, so as to fully ensure the vehicle's driving, which can ensure that the main systems of the vehicle (such as engine control, braking system, steering system, etc.) obtain sufficient power support, thereby maintaining the best working state, helping to improve the vehicle's response speed, acceleration performance and overall stability, and ensuring that the vehicle can operate safely and reliably when driving at extreme speed. When the vehicle is in the slow speed mode, the demand for power and power is relatively low. At this time, the control module controls the on-off switch 21 to be connected, and controls the DC converter and the standby generator to supply power to the installed equipment at the same time in the full power state, which can provide sufficient power support for the installed equipment while ensuring the normal operation of the vehicle, ensuring that the installed equipment can respond quickly and play a role in an emergency.

[0047] In this embodiment, the working mode of the vehicle may also include an off mode. When the vehicle is in the off mode, there is no need to supply power to the additional device 100a, and the vehicle has been used and is in a standby or off state. At this time, the control module 30 is also used to control the on-off switch to be turned off and control the backup power supply 12 to shut down and stop supplying power to the additional device 100a when the vehicle is in the off mode.

[0048] Optionally, the safety on-off power control system further includes a switch 40, and the switch 40 has a plurality of working gears corresponding one-to-one to the working modes of the vehicle.

[0049] The control module 30 is electrically connected to the switch 40 , and is used to obtain the actual working gear position of the switch 40 , and determine the corresponding working mode of the vehicle according to the actual working gear position of the switch 40 .

[0050] Specifically, the switch 40 has a normal mode gear, a high-speed mode gear, a slow mode gear and an OFF gear corresponding to the normal mode, high-speed mode, slow mode and off mode of the vehicle. The user can manually control the switch 40 to select different gears according to actual needs. For example, after the vehicle is started, if some additional equipment needs to be used, the actual working gear of the switch can be switched to the normal mode gear; when the vehicle needs to travel at high speed, the actual working gear of the switch can be switched to the high-speed mode gear; when the vehicle needs to travel slowly, the actual working gear of the switch can be switched to the slow mode gear; when the vehicle does not need to use additional equipment, the actual working gear of the switch can be switched to the OFF gear.

[0051] In this embodiment, the switch 21 is connected to the control module 30 through a signal line, and the control module is connected to the power supply module 10 through a signal line.

[0052] Optional, such as Figure 1 As shown, the control module 30 includes a first control module 31 and a second control module 32. The first control module 31 is used to control the on and off of the on / off switch 21; the second control module 32 is used to control the working states of the main power supply 11 and the backup power supply 12.

[0053] In this embodiment, the first control module may be a SOC chip, which is integrated in the safety on-off module 20 and electrically connected to the on-off switch 21 to control the on-off of the on-off switch 21. The second control module 32 may be a vehicle control unit (VCU), which is a core component in the electronic control system of an electric vehicle and is responsible for coordinating and controlling various subsystems in the vehicle to ensure the normal operation and performance optimization of the vehicle.

[0054] Optionally, the second control module 32 is also electrically connected to the motor controller of the vehicle. When the vehicle is in different modes, the second control module 32 is also used to send relevant control signals to the motor controller so that the motor controller controls the speed and torque of the motor according to the relevant control signals, thereby changing the vehicle speed. For example, when the vehicle is in slow mode, a first control signal is sent to the motor controller, and the first control signal is used to instruct the motor controller to control the speed and torque of the motor so that the vehicle travels slowly; when the vehicle is in high-speed mode, a second control signal is sent to the motor controller, and the second control signal is used to instruct the motor controller to control the speed and torque of the motor so that the vehicle travels at high speed. This is a conventional technology in the art and will not be repeated here.

[0055] It should be noted that special-purpose vehicles need to ensure the priority of special equipment. In normal mode and rapid mode, if special equipment is turned on by human intervention, the second control module 32 will control the maximum output power of the DC converter to be limited to, for example, 80% of the rated output power, so as to reserve 20% for powering the additional equipment. At the same time, the motor controller can be controlled to reduce the acceleration performance of the vehicle. In addition, special working conditions may be encountered during vehicle driving. For example, after a collision, the user switches the gear of the switch to the slow mode. At this time, the backup generator is forced to start, and the normal operation of the special additional equipment can still be guaranteed in the case of vehicle damage.

[0056] Optionally, the safety on / off module 20 further includes fuses 22 arranged on the main power supply circuit 20a and the backup power supply circuit 20b.

[0057] like Figure 1 As shown, the output ends of the main power supply circuit 20a and the backup power supply circuit 20b are electrically connected to multiple installed devices 100a through multiple branches, and each branch is provided with a fuse corresponding to the multiple installed devices 100a. When the current abnormally rises to a certain height and temperature, the fuse can melt itself to cut off the current, thereby protecting the safe operation of the circuit.

[0058] Optionally, the safety on-off module 20 further includes a detection unit 23 disposed on the main power supply circuit, and the detection unit 23 includes at least one of a temperature sensor and a current sensor. The control module 30 is also used to: obtain a target parameter value detected by the detection unit 23, and when the target parameter value is higher than a preset parameter threshold, control the on-off switch 21 to disconnect, and the target parameter value is a temperature value or a current value.

[0059] Specifically, when the current sensor detects that the current value on the main power supply circuit is higher than the preset current threshold, or when the temperature sensor detects that the temperature value on the main power supply circuit is higher than the preset temperature threshold, the on-off switch 21 is controlled to be disconnected to cut off the main power supply circuit to prevent the circuit from short circuit, overload and other faults, and to avoid the installed equipment 100a from being damaged by excessive current shock.

[0060] Based on the same inventive concept, an embodiment of the present invention also provides a method for safe power on and off control of a vehicle, which uses a safe power on and off control system such as the above embodiment to achieve power on and off control of vehicle-installed equipment. This method can be executed by the control module 30 in the above safety power on and off control system. Figure 2 is a flow chart of a safe power on / off control method provided by an embodiment of the present invention, such as Figure 2 As shown, the safe power on and off control method includes:

[0061] Step S210: Obtain the current working mode of the vehicle.

[0062] In this embodiment, the working mode of the vehicle includes at least a normal mode, an extreme speed mode and a slow speed mode. The current working mode of the vehicle can be determined by the control module 30 by obtaining the actual working gear position of the switch 40. The actual working gear position of the switch 40 is selected and switched by the user as needed.

[0063] Step S220: According to the current working mode of the vehicle, the on-off switch and the working status of the main power supply and the backup power supply are controlled so that at least one of the main power supply and the backup power supply supplies power to the added equipment, or stops supplying power to the added equipment.

[0064] Optionally, step S220 includes:

[0065] When the vehicle is in normal mode, the on-off switch is controlled to be connected, and the main power supply is controlled to work to supply power to the additional equipment; when the output power of the main power supply exceeds the set power threshold, the backup power supply is controlled to work and supply power to the additional equipment at the same time as the main power supply;

[0066] When the vehicle is in the extreme speed mode, the on-off switch is controlled to be disconnected, and the backup power supply is controlled to be shut down, and the power supply to the installed equipment is stopped;

[0067] When the vehicle is in slow mode, the on-off switch is controlled to be connected, and the main power supply and the backup power supply are controlled to supply power to the added equipment at the same time in full power state.

[0068] In this embodiment, the working mode of the vehicle may also include an off mode. When the vehicle is in the off mode, there is no need to power the additional equipment, and the vehicle has been used and is in a standby or off state. Then step S820 may also include:

[0069] When the vehicle is in shutdown mode, the on-off switch is controlled to be disconnected, and the backup power supply is controlled to be shut down, and power supply to the added equipment is stopped.

The processor executes various functional applications and data processing of the processor by running the non-transient software programs, instructions and modules stored in the memory, that is, to realize the safe on-off power control in the above-mentioned method embodiment.
