[0035] Figure 3This is a schematic diagram illustrating the process of performing high-voltage power supply control operations in one embodiment of the vehicle-mounted integrated control system of the present invention.

[0036] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0037] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0038] This invention provides an in-vehicle integrated control system for controlling vehicle operation.

[0039] In this embodiment of the invention, reference is made to Figure 1 The vehicle-mounted integrated control system includes a main controller 1. The main controller 1 includes a main chip 11 mounted on a circuit board. The main chip 11 includes a processor 1001, a memory 1002, a timer 1003, etc. The memory 1002 can be a high-speed RAM memory, a stable memory (non-volatile memory), or a Flash memory, SRAM memory, SDRAM memory, etc.

[0040] like Figure 1 As shown, the memory 1002, as a storage medium, may include vehicle control programs, which include: a vehicle control program, a battery management program, a motor drive control program, and a heat pump management program. Figure 1 In the device shown:

[0041] When the vehicle control program is executed by the processor, it implements first operational control operations related to the vehicle's power system and / or braking system.

[0042] When the battery management program is executed by the processor, it implements a second operation control operation of the vehicle's power supply.

[0043] When the motor drive control program is executed by the processor, it implements the third operation control operation of the vehicle's motor.

[0044] When the heat pump management program is executed by the processor, it implements the fourth operation control operation of the vehicle's heat pump system.

[0045] The first set of operational control operations includes power control operations, energy recovery control operations, and / or engine compartment thermal management operations. Power control operations are speed-related control operations used to control the movement of the vehicle. Energy efficiency control operations include operations such as controlling the recovery and utilization of energy generated on the vehicle. Engine compartment thermal management operations are control operations used to regulate the heat of the engine compartment operating environment.

[0046] Specifically, the power control operations include vehicle acceleration control, vehicle deceleration control, and vehicle gear shifting control. During the execution of power control operations, the relevant control commands for vehicle speed control can be determined based on received user control commands or monitoring parameters input by the on-board detection module, and the operation of the power system and / or braking system can be controlled according to the control commands. During the execution of energy recovery control operations, when the main chip 11 receives a signal of accelerator pedal release or brake pedal depressing, it can control relevant components to convert the kinetic energy in the power system into electrical energy and store it in the power battery pack. It can also realize vehicle deceleration through the accelerator pedal. During the execution of engine compartment thermal management operations, the main chip 11 can receive state parameters related to engine operation in the power system (such as temperature, air pressure, etc.), and operate the cooling system and other components according to the state parameters to ensure that the engine can operate normally within the appropriate operating temperature range.

[0047] The second operation control operation includes high-voltage power supply control operation, charging control operation, and / or battery control operation. The high-voltage power supply control operation specifically controls the power-on and power-off of the power supply in the high-voltage circuit. The charging control operation specifically controls the start-up, stop, and charging speed of the vehicle battery. The battery control operation specifically monitors and controls the battery's lifespan, charge level, and on / off status.

[0048] The third operation control operation includes torque control of the motor and / or power inverter control of the motor. The torque control operation is used to control the magnitude of the motor's operating torque; specifically, the motor is a vehicle-drive motor located on the high-voltage circuit. The power inverter control operation is used to control the power inverter process connected to the motor.

[0049] The fourth operation control includes the control operation of the electromagnetic components and / or water pump in the heat pump system. Specifically, it may include operations such as controlling the opening degree and closing of the electromagnetic components and / or the opening and closing, and speed of the water pump.

[0050] During the execution of the above control operations, the main controller 1 can receive corresponding signals (such as detection signals and / or equipment operation signals) and output control commands to the corresponding vehicle components based on the received signals. The types of signals received include: power signals, wake-up signals, analog signals, digital signals, pulse signals, resolver signals, communication bus signals, and / or serial communication signals.

[0051] The main controller 1 is specifically located in the low-voltage circuit of the vehicle and is powered by a low-voltage power supply.

[0052] This invention proposes an integrated vehicle control system that integrates vehicle control programs, battery control programs, motor drive control programs, and heat pump management programs onto a single controller. This eliminates the need for separate controllers for these functions, instead allowing a single controller to handle them all. This reduces the amount of software and hardware required for vehicle control, simplifies the vehicle control architecture, and improves overall control efficiency and performance. Furthermore, integration significantly reduces the number of controller components, achieving the goals of lowering development costs, increasing development efficiency, and enhancing controller performance, integration, and reliability within the power domain.

[0053] In this embodiment, the control of the high-voltage power supply is performed by the integrated main controller 1. Compared with the independent operation of different controllers, the high-voltage power supply in this embodiment cannot bypass the main controller 1. Even if other components on the vehicle send control commands for the high-voltage power supply through the communication bus, the vehicle will not be able to move. Based on this, the multi-functional integrated main controller 1 in this embodiment is conducive to improving vehicle information security and enhancing vehicle control accuracy.

[0054] Furthermore, in this embodiment, in addition to the main chip 11 in which multiple programs are integrated into the main controller 1, the main controller 1 also includes a communication bus (CAN) and an electrically erasable programmable read-only memory (EEPROM).

[0055] Furthermore, based on the above embodiments, another embodiment of the vehicle-mounted integrated control system of this application is proposed. In this embodiment, reference is made to... Figure 2 The torque control operations described above include:

[0056] Step S10: Receive the gear position information and pedal status information of the vehicle.

[0057] Gear information includes the vehicle's current gear. Pedal status information includes the current pedal opening and / or the rate of change of pedal opening. It should be noted that gear information and status information can be input to the main controller according to the signal types mentioned above.

[0058] Step S20: Determine the torque control signal based on the gear position information and the status information;

[0059] Different gear positions and different status information correspond to different torque control signals. The torque control signal may include the target torque that the motor needs to achieve.

[0060] Step S30: Output the torque control signal to the drive board 2 of the motor, so that the drive board 2 drives the motor to run according to the torque control signal.

[0061] The driver board 2 is specifically an execution unit used to drive the operation of the motor. It should be noted that the driver board 2 does not have its own control hardware. The driver board 2 includes multiple isolated power supplies and a driver chip connected to each isolated power supply; all driver chips are connected to the motor. The driver board 2 may also include an analog sampling module and an isolated sampling module for detecting motor operating parameters and feeding them back to the main controller. The drive control signal can be input to the driver board 2 via electrical signals.

[0062] After receiving the drive control signal, the drive board 2 operates according to the drive control signal to achieve the corresponding target torque.

[0063] In this embodiment, the integrated main controller 1 receives information about the pedal and gear position, and sends torque control signals to the motor drive board 2 to realize the vehicle's movement, which helps to improve the vehicle's information security.

[0064] Furthermore, based on any of the above embodiments, another embodiment of the vehicle-mounted integrated control system of this application is proposed. In this embodiment, reference is made to... Figure 3 The high-voltage power supply control operation includes:

[0065] Step S40: Receive power-on command and obtain the vehicle's operating status information;

[0066] The operational status information here may include operational information of various components on the vehicle (such as the status information of the power system), power demand information, and / or fault status information. This operational status information can be input to the main controller 1 using the signal types mentioned above.

[0067] Step S50: Determine the power-on mode of the vehicle based on the operating status information;

[0068] Different operating status information corresponds to different power-on modes.

[0069] Specifically, when the operating status information meets the driving conditions, it indicates that the preparations required for the current vehicle driving have been completed, and the power-on mode can be determined as the preparation power-on mode; when the operating status information meets the slow charging conditions, it indicates that the vehicle currently needs to be charged and the charging rate needs to be limited to below the preset rate, and the power-on mode can be determined as the slow charging power-on mode; when the operating status information meets the fast charging conditions, it indicates that the vehicle currently needs to be charged and the charging rate needs to reach above the preset rate, and the power-on mode can be determined as the fast charging power-on mode; when the operating status information meets the other power-on requests besides the regular driving needs, the power-on mode can be determined as the ETC power-on mode; when the operating status information meets the system fault conditions, the power-on mode can be determined as the power-off mode.

[0070] Step S60: Determine the target operating parameters of the relays in the high-voltage circuit of the vehicle according to the power-on mode;

[0071] The target operating parameters include the on / off control parameters of the relays.

[0072] There may be one or more relays in a high-voltage circuit. Different power-on modes correspond to different relays. Specifically, the target relay in the high-voltage circuit can be determined based on the power-on mode, and the target operating parameter of the target relay is determined to be "on". The target operating parameter of other relays besides the target relay is determined to be "off".

[0073] Step S70: Control the relay to operate according to the target operating parameters so that the high-voltage power supply operates in the power-on mode.

[0074] In this embodiment, the high-voltage power-on control is achieved through the integrated main controller 1 in the above manner, eliminating the need for signal transmission conversion between multiple controllers, thereby effectively improving the control efficiency of vehicle power-on.

[0075] Furthermore, based on any of the above embodiments, another embodiment of the vehicle-mounted integrated control system of this application is proposed. In this embodiment, reference is made to... Figure 1 The main controller 1 includes a level conversion unit 12 connected to the main chip 11, and the level conversion unit 12 is connected to the drive board 2 of the motor.

[0076] The level conversion unit 12 is used to receive the first digital signal corresponding to the third operation control operation sent by the main chip 11, and convert the first digital signal into a corresponding first level signal and send it to the motor drive board 2;

[0077] The level conversion unit 12 is also used to receive a second level signal representing the detection parameters of the motor sent by the driver board 2, and convert the second level signal into a second digital signal and send it to the main chip 11.

[0078] The first digital signal is specifically the control command used to control the drive board 2 in the third operation control process. Different control signals can correspond to different first level signals. Specifically, different torque control signals can correspond to different first level signals.

[0079] The detection parameters are specifically the parameters detected by the analog sampling module and the isolated sampling module mentioned above. These parameters are sent to the level conversion unit 12 in the form of a second-level signal. Different detection parameters correspond to different second-level signals, and different second-level signals are converted into different second digital signals. After receiving the second digital signal, the main chip 11 can determine the corresponding control command to operate the motor or other components on the vehicle based on the second digital signal.

[0080] In this embodiment, the above method helps to further improve the driving efficiency of the integrated controller for the motor.

[0081] Furthermore, based on any of the above embodiments, another embodiment of the vehicle-mounted integrated control system of this application is proposed. In this embodiment, reference is made to... Figure 1 The heat pump system includes a first relay and an electromagnetic element. The main controller 1 also includes a low-side driver 13 connected to the main chip 11. The low-side driver 13 is used to receive a first control command corresponding to the first relay and / or the electromagnetic element sent by the main chip 11 for the fourth operation control operation, and to operate according to the first control command so that the first relay and / or the electromagnetic element reaches the first target state corresponding to the first control command.

[0082] Specifically, the low-side driver 13 may be electrically connected to the first relay and / or electromagnetic element.

[0083] The first control command may include the opening and closing control command of the first relay and / or the opening and closing control command of the electromagnetic element, etc.

[0084] In this embodiment, the above method eliminates the need for signal conversion and transmission between multiple controllers. The integrated controller directly controls the first relay and electromagnetic components in the heat pump system, thereby improving the control efficiency of the vehicle-mounted heat pump system and ensuring that the heat pump system can quickly reach the target state required for operation.

[0085] Furthermore, based on any of the above embodiments, another embodiment of the vehicle-mounted integrated control system of this application is proposed. In this embodiment, reference is made to... Figure 1 The main controller 1 further includes a high-side driver 14 connected to the main chip 11. The high-side driver 14 is used to receive the second control command of the second relay in the high-voltage circuit corresponding to the second operation control operation sent by the main chip 11 and to run according to the second control command so that the second relay reaches the second target state corresponding to the second control command.

[0086] The second relay is electrically connected to the high-side driver 14. Specifically, the second relay can be the relay corresponding to the aforementioned power-on mode. Specifically, controlling the relay operation according to the target operating parameters involves inputting a second control command corresponding to the target operating parameters to the high-side driver 14, causing the high-side driver 14 to operate according to the second control command, thereby enabling the second relay to reach the target state corresponding to the aforementioned power-on mode.

[0087] In this embodiment, the above method eliminates the need for signal conversion and transmission between multiple controllers. The integrated controller can directly control the second relay in the high-voltage circuit, thereby improving the control efficiency of powering on and off the high-voltage circuit and ensuring that the high-voltage circuit can quickly reach the target state required for operation.

[0088] Furthermore, based on any of the above embodiments, another embodiment of the vehicle-mounted integrated control system of this application is proposed. In this embodiment, reference is made to... Figure 1 The heat pump system includes a water pump, and the main controller 1 further includes a pulse modulator 15 connected to the main chip 11. The pulse modulator 15 is used to receive the third control command of the water pump corresponding to the fourth operation control operation sent by the main chip 11 and operate according to the third control command so that the water pump reaches the third target state corresponding to the third control command.

[0089] A heat pump system may include a water circulation loop, on which a water pump is installed.

[0090] Specifically, the main chip 11 can determine the target operating power of the water pump based on the received demand signal, determine the on / off cycle of the water pump based on the target operating power, determine the target duty cycle of the water pump control signal based on the on / off cycle, and output the corresponding third control command to the pulse modulator 15 according to the target duty cycle. The pulse modulator 15 outputs the corresponding pulse signal to the water pump according to the target duty cycle, so that the water pump operates according to the required on / off cycle.

[0091] In this embodiment, the above method eliminates the need for signal conversion and transmission between multiple controllers. The integrated controller directly controls the water pump in the heat pump system, thereby improving the control efficiency of the water pump in the heat pump system and ensuring that the heat pump system can quickly reach the desired target state.

[0092] Furthermore, based on any of the above embodiments, another embodiment of the vehicle-mounted integrated control system of this application is proposed. In this embodiment, the vehicle-mounted integrated control system includes a slave controller 3, which is connected to the main controller 1. The slave controller 3 includes a high-voltage acquisition module, a temperature / current acquisition module, and a detection module. The slave controller 3 is used to acquire the operating status data of the vehicle's battery pack through the high-voltage acquisition module, the temperature / current acquisition module, and the detection module and send it to the main controller 1. The second operation control operation includes determining a power management command based on the operating status data.

[0093] The high-voltage acquisition module collects cell voltage data from the battery pack. The temperature / current acquisition module collects current or temperature data from the battery pack. The detection module specifically detects battery charge and power consumption. The battery pack's operating status data includes high-voltage data, current data, and power consumption data.

[0094] Specifically, the controller 3 is located inside the battery pack, which includes multiple battery groups. Different acquisition modules (including high voltage acquisition module, temperature / current acquisition module, detection module, etc.) can be set in the controller 3 for different battery groups. Different acquisition modules collect the operating status data of different battery groups.

[0095] It should be noted that controller 3 refers to the speed of the engine, which has data acquisition control function but no other control function.

[0096] When the controller 3 receives a data detection command from the main controller 1, it can feed back the detected operating status data to the main controller 1. Alternatively, it can periodically send the detected operating status data to the main controller 1.

[0097] Specifically, the second operation control operation includes a high-voltage power supply control operation, which can determine the high-voltage power supply power-on or power-off command based on the number of operating states; the second operation control operation includes a charging control operation, which can determine the charging control command based on the operating state data; and the second operation control operation includes a battery control operation, which can control the battery's on / off state command based on the operating state data.

[0098] In this embodiment, the integrated controller can monitor battery data and perform battery management control operations based on the monitoring results, thereby reducing the data processing required between the battery pack and the main controller 1 through different controllers and effectively improving the vehicle's battery management efficiency.

[0099] Furthermore, this invention also proposes a vehicle that includes the vehicle-mounted integrated control system described in any of the above embodiments. The vehicle includes all the components and functions of the aforementioned vehicle-mounted integrated control system; therefore, the vehicle can achieve the technical effects achievable by any of the above embodiments of the vehicle-mounted integrated control system, which will not be elaborated upon further here.
