DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Most motor controls on vehicles need to meet low energy consumption requirements, because low energy consumption can extend battery life and improve the overall vehicle energy efficiency. Especially for new-age vehicles, it is very important to control the vehicle's components to enter a dormant state, which helps reduce the power consumption of the entire vehicle, extend the vehicle's life, and improve energy utilization. However, in the prior art, some vehicles cannot effectively control certain components to enter a dormant state when they are not needed. This may lead to unnecessary energy waste and affect the overall performance and energy efficiency of the vehicle.

[0022] Therefore, in order to solve the above technical problems, Figure 1 and Figure 2 As shown, the utility model provides a sleep control circuit, a vehicle system and a vehicle and a sleep control system for the vehicle.

[0023] like Figure 1 and Figure 2 As shown, the sleep control circuit 100 includes: a main control chip 10, a sleep protection module 20, a voltage regulation module 30 and a sampling module 40. The main control chip 10 is electrically connected to the vehicle communication module 200 and the vehicle power module 300 respectively; the sleep protection module 20 is electrically connected to the main control chip 10 and the voltage regulation module 30 respectively; the sampling module 40 is electrically connected to the voltage regulation module 30, and the voltage regulation module 30 is used to provide a power supply voltage for the sampling module 40; wherein, the main control chip 10 is used to receive a sleep instruction issued by the vehicle communication module 200, and disconnect the sleep protection module 20 according to the sleep instruction.

[0024] Specifically, the sleep control circuit 100 is specifically used in the vehicle system. The main control chip 10 is electrically connected to the vehicle communication module 200 and the vehicle power module 300 in the vehicle system. The vehicle power module 300 is used to supply power to the main control chip 10, and the vehicle communication module 200 is used to send a sleep instruction to the main control chip 10. The sleep protection module 20 is electrically connected to the main control chip 10 and the voltage regulation module 30, respectively, and the voltage regulation module 30 is used to provide a power supply voltage for the sampling module 40.

[0025] Therefore, when the main control chip 10 receives the sleep command issued by the vehicle communication module 200, the main control chip 10 will disconnect the sleep protection module 20 according to the sleep command. In this way, the voltage regulation module 30 cannot supply voltage to the sampling module 40, and the sampling module 40 stops working and enters the sleep mode, so that the entire circuit enters the low power consumption mode, effectively managing the energy consumption in the circuit, and ensuring that the sampling module 40 is put into sleep state when it is not needed, thereby achieving the effect of improving the energy efficiency and performance of the circuit.

[0026] At the same time, the vehicle communication module 200 will also send a wake-up instruction to the main control chip 10. When the main control chip 10 receives the wake-up instruction issued by the vehicle communication module 200, the main control chip 10 will connect the sleep protection module 20 to the circuit according to the sleep instruction. In this way, the voltage regulation module 30 will continue to supply voltage to the sampling module 40, and the sampling module 40 in the sleep state will stop sleeping and enter the working mode.

[0027] Further, in a possible implementation, a low voltage dropout regulator 11 is provided in the main control chip 10, and the low voltage dropout regulator 11 is electrically connected to the sleep protection module 20. That is, the main control chip 10 is the main control chip 10 having the low voltage dropout regulator 11. The main control chip 10 may be a chip of model STM32F446RET6.

[0028] Further, for the specific circuit structure of the sleep control circuit 100, the sleep protection module 20 includes: a first resistor R1, a first MOS transistor Q1 and a first capacitor C1; one end of the first resistor R1 is respectively connected to the low voltage difference regulator 11 of the main control chip 10 and the source of the first MOS transistor Q1 and connected to a voltage of 5V; the other end of the first resistor R1 is respectively connected to the IO port of the main control chip 10 and the gate of the first MOS transistor Q1; one end of the first capacitor C1 is respectively connected to the drain of the first MOS transistor Q1 and the voltage regulation module 30, and the other end of the first capacitor C1 is grounded. Wherein, the first MOS transistor Q1 is a PMOS transistor.

[0029] In this way, the sleep protection module 20 can be a protection module with MOS tube as the main body. When the main control chip 10 receives the sleep instruction issued by the vehicle communication module 200, the main control chip 10 will disconnect the first MOS tube Q1 according to the sleep instruction. The voltage regulation module 30 will be disconnected from the circuit, so that the voltage regulation module 30 cannot supply voltage to the sampling module 40, and the sampling module 40 stops working and enters the sleep mode, so that the entire circuit enters the low power consumption mode, effectively managing the energy consumption in the circuit, and ensuring that the sampling module 40 is put into sleep state when it is not needed, thereby achieving the effect of improving the energy efficiency and performance of the circuit. In addition, the voltage regulation module 30 can be specifically a VRS voltage ( Figure 2 VRS in ).

[0030] Further, in a possible implementation, the sampling module 40 includes: an angle sensor IC41, a temperature sensor IC42, and a current sensor IC43; the angle sensor IC41, the temperature sensor IC42, and the current sensor IC43 are electrically connected to the voltage regulating module 30, respectively. The angle sensor IC41, the temperature sensor IC42, and the current sensor IC43 are specifically connected to the VRS voltage. The temperature sensor IC42 and the current sensor IC43 are respectively connected to the VRS voltage in the voltage regulating module 30 and grounded.

[0031] The temperature sensor IC42 can be electrically connected to the engine, gearbox, braking system, air-conditioning system, cooling system, etc. of the automobile to monitor the temperature of the corresponding position in real time; the current sensor IC43 can be electrically connected to the battery, generator, engine control unit (ECU), electric motor, charging system, etc. of the automobile to monitor the change of current at the corresponding position to ensure the battery charging status, engine running status, electrical load status, etc., so as to ensure the normal operation, energy saving and safety of the automobile; the angle sensor IC41 can be electrically connected to the steering system, steering assist system, body control module, etc. of the automobile to monitor the steering angle, body tilt angle, tire rolling angle, etc. of the vehicle, so as to monitor the posture and driving direction of the vehicle in real time.

[0032] Furthermore, for the specific electrical connection mode between the main control chip 10 and the vehicle communication module 200 and the vehicle power module 300 in the vehicle system. The main control chip 10 first connects to the positive electrode of the vehicle battery in the vehicle power module 300 ( Figure 2 KL30 in the vehicle power module 300) and the vehicle battery negative electrode ( Figure 2 In addition, the main control chip 10 is also connected to the vehicle communication CANH ( Figure 2 CANH in the vehicle power module 300 and vehicle communication CANL ( Figure 2 CANL) connection in .

[0033] As for the specific working mode of the sleep control circuit 100, the low voltage difference regulator 11 in the main control chip 10 can convert the voltage provided by the positive electrode of the vehicle battery into a voltage of VCC_5V to supply the main control chip 10 for use, and can also power the voltage regulation module 30.

[0034] When the positive pole of the vehicle battery powers on the main control chip 10, the main control chip is in a dormant state. When the main control chip 10 receives a CAN message through the vehicle communication CANH and the vehicle communication CANL, the main control chip 10 will be awakened, and the main control chip 10 will switch to a standby state. At the same time, the IO port of the main control chip 10 will output a low level to the first MOS tube Q1, and the first MOS tube Q1 will be closed, and the voltage regulation module 30 will output a voltage to the angle sensor IC41, the temperature sensor IC42 and the current sensor IC43 in the sampling module 40, so that the sampling module 40 works, and the entire dormancy control circuit 100 is in a standby state. When the main control chip 10 receives a sleep command through the vehicle communication CANH and the vehicle communication CANL, the IO port of the main control chip 10 will output a high level to the first MOS tube Q1, and the first MOS tube Q1 will be disconnected, so that the voltage regulation module 30 cannot output voltage to the angle sensor IC41, the temperature sensor IC42 and the current sensor IC43 in the sampling module 40.

[0035] On the other hand, the utility model also provides a vehicle system, which includes: a vehicle power module 300, a vehicle communication module 200, and the above-mentioned sleep control circuit 100 electrically connected to the vehicle power module 300 and the vehicle communication module 200 respectively.

[0036] In addition, the utility model also provides a vehicle, which includes: the vehicle system described above.

[0037] Therefore, in summary, the utility model provides a sleep control circuit, a vehicle system and a vehicle. In the utility model, when the main control chip receives the sleep command issued by the vehicle communication module, the main control chip will disconnect the sleep protection module according to the sleep command, so that the voltage regulation module cannot supply voltage to the sampling module, and the sampling module stops working and enters the sleep mode, so that the entire circuit enters the low power consumption mode, effectively manages the energy consumption in the circuit, and ensures that the sampling module is put into a sleep state when it is not needed, thereby achieving the effect of improving the energy efficiency and performance of the circuit.
