The accompanying drawings are for illustration purposes only and are not to be considered as limiting the present invention. The same reference symbols are used throughout the drawings to represent the same components. In the drawings:

[0035] Figure 2 This is a flow chart of a safe power on / off control method provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction 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 solution of the present application, rather than limitations on the technical solution 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 FIG. 1 is a circuit diagram of a vehicle safety on / off 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 power the vehicle's additional equipment 100a. The safety on / off module 20 includes a main power supply circuit 20a, which is arranged between the main power supply 11 and the additional equipment 100a, and a backup power supply circuit 20b, which is arranged between the backup power supply 12 and the additional equipment 100a. The main power supply circuit 20a is provided with an on / off switch 21. 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 state of the on / off switch 21, as well as the operating state of the main power supply 11 and the backup power supply 12, when the vehicle is in different operating modes, so that at least one of the main power supply 11 and the backup power supply 12 can supply power to the additional equipment 100a or stop 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 can 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's 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 has 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 requirements, so as to meet the power supply requirements of high-power installed equipment.

[0041] Specifically, such as Figure 1As shown, the output end of the DC converter is electrically connected to one end of an on-off switch 21, and the other end of the on-off switch 21 is electrically connected to an additional device, forming a main power supply circuit 20a. There are multiple additional devices 100a, and the other end of the on-off switch 21 is electrically connected to each of the multiple additional devices 100a. The output end of the backup generator is connected to the other end of the on-off switch 21, and thus electrically connected to the multiple additional devices 100a, forming a backup power supply circuit 20b. The backup generator and the DC converter are connected in parallel. When the backup generator and the DC converter operate simultaneously, the current in the circuit can be increased, thereby meeting the power supply needs of high-power additional devices.

[0042] Optionally, the on / off switch 21 is a relay. The relay can isolate the circuits, preventing direct connection between the main power supply 11 and the installed device 100a, thereby reducing mutual interference between the circuits and potential damage risks. Relays also have advantages such as long life, strong impact resistance, and resistance to damage.

[0043] In this embodiment, the vehicle's operating modes include at least a normal mode, a top-speed mode, and a slow mode. The normal mode refers to the vehicle's normal driving mode, the top-speed mode refers to the vehicle's top-speed driving mode (i.e., the vehicle speed is greater than a maximum speed threshold, which is typically the best speed a car can achieve on a level, good road surface and can be obtained through calibration), and the slow mode refers to the vehicle's slow driving mode (i.e., the vehicle speed is less than a minimum speed threshold, which varies depending on the gear position and vehicle design. For example, the minimum speed threshold corresponding to first gear may be between 0 and 5 km / h, which is suitable for situations requiring high torque, such as starting or climbing).

[0044] Optionally, the control module 30 is configured 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 power the vehicle's own electrical equipment. When the on-off switch is connected, the DC converter also needs to power 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 backup generator to start working and simultaneously power the additional equipment 100a together with the DC converter to improve power supply reliability and prevent the DC converter from overloading, thereby causing electrical components to overheat and burn, seriously affecting the stability and safety of the vehicle's electrical system. When the vehicle is in the top-speed mode, the vehicle's electrical and power systems are often in a high-load state. Any unnecessary power consumption may have an adverse effect on the vehicle's performance and safety. At this time, the control module 30 controls the on-off switch to be disconnected, and controls the backup power supply to be shut down, and stops supplying power to the added equipment 100a, so as to fully ensure the vehicle's driving. This can ensure that the vehicle's main systems (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 top speed. When the vehicle is in the slow mode, the demand for electricity 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 backup generator to supply power to the added equipment at full power at the same time. This can ensure the normal operation of the vehicle while providing sufficient power support for the added equipment, ensuring that the added equipment can respond quickly and function in an emergency.

[0047] In this embodiment, the vehicle's operating mode may also include an off mode. In the off mode, the vehicle does not need to power the additional device 100a, and the vehicle has been used and is in a standby or off state. In this case, the control module 30 is further configured to control the on-off switch to be turned off and the backup power supply 12 to be shut down, thereby stopping power supply to the additional device 100a.

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

[0049] The control module 30 is electrically connected to the switch 40 . The control module 30 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 vehicle's normal mode, high-speed mode, slow mode, and off mode. 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 at a slow speed, 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 communicatively connected to the control module 30 via a signal line, and the control module is communicatively connected to the power supply module 10 via 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 / 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 into the safety on / off module 20 and electrically connected to the on / off switch 21 to control the on / off state of the on / off switch 21. The second control module 32 may be a vehicle control unit (VCU), which is a core component of the electric vehicle's electronic control system and is responsible for coordinating and controlling various subsystems in the vehicle to ensure normal operation and optimized performance of the vehicle.

[0054] Optionally, the second control module 32 is also electrically connected to the vehicle's motor controller. When the vehicle is in different modes, the second control module 32 is further configured to send relevant control signals to the motor controller, so that the motor controller controls the motor speed and torque 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, the first control signal being used to instruct the motor controller to control the motor speed and torque, causing the vehicle to travel at a slow speed; when the vehicle is in high-speed mode, a second control signal is sent to the motor controller, the second control signal being used to instruct the motor controller to control the motor speed and torque, causing the vehicle to travel at a high speed. This is conventional technology in the art and will not be further described here.

[0055] It should be noted that special-purpose vehicles require that special equipment be prioritized. If a special equipment is manually activated in normal or rapid modes, the second control module 32 will limit the maximum output power of the DC converter to, for example, 80% of the rated output power, reserving 20% ​​for powering the additional equipment. The motor controller can also be controlled to reduce the vehicle's acceleration performance. Furthermore, the vehicle may encounter special operating conditions during driving. For example, after a collision, the user may shift the toggle switch to slow mode, forcing the backup generator to start. This ensures the normal operation of the special equipment even if the vehicle is damaged.

[0056] Optionally, the safety on / off module 20 further includes fuses 22 provided 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 additional devices 100a through multiple branches. Each branch is equipped with a fuse corresponding to each of the multiple additional devices 100a. When the current abnormally rises to a certain level and temperature, the fuse will melt and 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, wherein the detection unit 23 includes at least one of a temperature sensor and a current sensor. The control module 30 is further configured to obtain a target parameter value detected by the detection unit 23 and control the on / off switch 21 to open when the target parameter value exceeds a preset parameter threshold. 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 circuiting, 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 controlling the safe power on and off of a vehicle, which uses a safe power on and off control system such as the above embodiment to realize the power on and off control of the vehicle-installed equipment. This method can be executed by the control module 30 in the above-mentioned safe power on and off control system. Figure 2 This is a flow chart of a safe power on / off control method provided by an embodiment of the present invention. Figure 2 As shown, the safe power on and off control method includes:

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

[0062] In this embodiment, the vehicle's operating modes include at least normal mode, high-speed mode, and slow mode. The vehicle's current operating mode can be determined by the control module 30 by obtaining the actual operating gear position of the switch 40. The actual operating gear position of the switch 40 is selected and switched by the user as needed.

[0063] Step S220: Control the on / off switch and the working status of the main power supply and the backup power supply according to the current working mode of the vehicle, so that at least one of the main power supply and the backup power supply supplies power to the additional equipment, or stops supplying power to the additional 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 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 full power at the same time.

[0068] In this embodiment, the vehicle's operating mode 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 installed equipment is stopped.
