[0017] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0018] Please refer to Figure 1 This illustration shows a schematic diagram of a vehicle control module for electric vehicles according to an embodiment of this application. The vehicle control module can be a purely hardware-based unit, which can be mounted on a processor chip. The vehicle control module includes: a vehicle control unit (VCU) 10, a body control module (BCM) 20, and a vehicle networking system 30.
[0019] Electric vehicles refer to automobiles that are powered by onboard power sources and whose wheels are driven by electric motors. It should be noted that, in this application's embodiments, the electric vehicle refers to a battery electric vehicle (BEV).
[0020] The vehicle controller is the core control device of an electric vehicle, responsible for controlling the vehicle's critical tasks. It receives driver input by collecting signals from the accelerator pedal, brake pedal, and gear position. It calculates the required torque for the electric vehicle by monitoring information from the Battery Management System (BMS) and Microcontroller Unit (MCU) in the powertrain system, and then sends commands to the MCU via signal lines to enable normal vehicle operation. In addition, the vehicle controller is also responsible for regenerative braking, energy management of the vehicle's drive system and battery, network management, fault diagnosis and handling, and vehicle status monitoring, thereby ensuring the vehicle operates normally and stably with good performance, high fuel economy, and high reliability.
[0021] The body control unit is an Electronic Control Unit (ECU) responsible for managing vehicle functions such as drive, anti-theft, and vehicle detection. For example, the body control unit may manage vehicle functions such as lighting, windows, door locks, and seat controls. The body control unit is connected to the vehicle controller via signal lines, allowing it to receive vehicle information from the vehicle controller.
[0022] The vehicle-to-everything (V2X) system includes a host unit, an in-vehicle T-BOX (Telematics-BOX), an application system interconnected with the electric vehicle, and a backend system. The host unit is primarily used for in-vehicle audio-visual entertainment and vehicle information display. The in-vehicle T-BOX communicates with the backend system and the application system, and acquires vehicle information, enabling real-time transmission and remote control of vehicle information. The application system interconnected with the electric vehicle refers to an application installed on a terminal device, such as a mobile phone, tablet, laptop, desktop computer, smart TV, or multimedia playback device. This application communicates with the backend system in the V2X system via a network. For example, the backend system can provide background services for the application system.
[0023] In some embodiments, when a user issues a control command through the application, the background system sends a monitoring request to the in-vehicle T-BOX. Upon receiving the monitoring request, the in-vehicle T-BOX sends a control message via a signal line to control the vehicle, and the result is then fed back to the application. This function allows users to remotely start the vehicle, open / close windows, and turn the air conditioning on / off.
[0024] In some embodiments, when a user issues an information retrieval command through the application, the background system sends an information retrieval request to the in-vehicle T-BOX. Upon receiving the request, the in-vehicle T-BOX retrieves the status information corresponding to at least one control unit included in the vehicle networking system via a signal line, and then sends the status information to the application's client for display. Through this function, users can obtain vehicle status information, such as speed, fuel consumption, and vehicle location, anytime, anywhere.
[0025] In some embodiments, the vehicle networking system 30 includes at least one control unit, each control unit being used to manage a vehicle function of the electric vehicle, and the vehicle controller 10 being connected to the body controller and at least one control unit via signal lines.
[0026] For example, the signal line can be a CAN (Controller Area Network) bus.
[0027] Each control unit is used to manage one vehicle function of the electric vehicle, and at least one control unit includes at least one of the following: Electronic Transmission Control System (EGS), Anti-lock Braking System (ABS), Ignition Control Module (ICM), Phase-change Memory (PCM), and Braking Unit.
[0028] The Electronic Transmission System (EGS) receives gear position information from the electric vehicle. The Gear Grid System (EGS) monitors the gear status of the electric vehicle; when the driver manually shifts gears, the EGS receives the gear position information promptly.
[0029] The Anti-lock Braking System (ABS) receives vehicle speed information from an electric vehicle. ABS improves braking performance, enhances driving safety, and prevents wheel lock-up (stopping rolling) during emergency braking, ensuring the driver can maintain directional control and preventing rear axle skidding. During braking, ABS uses highly sensitive wheel speed sensors on each wheel to detect wheel lock-up. The vehicle controller then controls the pressure regulator to release pressure in the brake calipers, preventing wheel lock-up. While the speedometer displays the theoretical speed when the user adjusts the vehicle speed using the accelerator and brake pedals, the actual speed can be obtained through ABS braking performance. Therefore, ABS can monitor the vehicle's speed and receive real-time speed information.
[0030] The ignition control module (ICM) receives the power status information from the electric vehicle. Based on this power status, the ICM manages the ignition function. Depending on environmental requirements, it can select either a metal probe or an ultraviolet photosensitive tube to achieve automatic ignition, flame indication, flameout alarm, and signal transmission. When the ICM is powered on, the power indicator light illuminates. When the switch is turned on, the system performs a self-test. After 0.6 seconds of ignition, the solenoid valve opens. If a flame signal is detected, ignition stops, and the indicator light illuminates. Therefore, the ICM can receive the electric vehicle's power status and enable vehicle starting upon power-on.
[0031] The engine control module (PCM) receives status information from the electric vehicle's engine. The PCM is a core component of the vehicle's engine control system, monitoring the engine's status. It receives signals from various sensors and controls engine start-up and shutdown by adjusting the feedback resistor of the PCM's internal power supply. Therefore, based on the engine status information received by the PCM, the electric vehicle's power status—whether it's on or off—can be determined.
[0032] The braking unit receives the pedal status of the electric vehicle, specifically the status of the brake pedal. The braking unit monitors the pedal status of the electric vehicle; when the driver presses the brake pedal, it indicates that the driver is decelerating. Therefore, the pedal status received by the braking unit can promptly reflect the driver's operating intentions.
[0033] In some embodiments, at least one control unit may further include an Electronic Stability Program (ESP), which analyzes vehicle driving information from various sensors and then sends corrective commands to ABS and other systems to help the vehicle maintain dynamic balance and improve vehicle safety and handling. ESP can be used to obtain the actual speed value of the electric vehicle.
[0034] In some embodiments, the vehicle controller 10 is used to receive vehicle information when the electric vehicle is in P gear, and transmit the vehicle information to the body controller. The vehicle information is used to indicate the vehicle status of the electric vehicle, and the vehicle information includes at least one status information received by at least one control unit.
[0035] P gear is the parking gear. When the user needs to park and not use the vehicle, they can shift to P gear. At this time, the wheels are mechanically locked to prevent them from rolling.
[0036] The vehicle controller receives vehicle information when the electric vehicle is in P gear and transmits the vehicle information to the body controller. The vehicle information is used to indicate the vehicle status when the electric vehicle is in P gear.
[0037] The vehicle information includes at least one status information received by at least one control unit, and the at least one status information includes at least one of the following: the gear position information of the electric vehicle received by the EGS, the vehicle speed information of the electric vehicle received by the ABS, the power status of the electric vehicle received by the ICM, the engine status information of the electric vehicle received by the PCM, and the pedal status of the electric vehicle received by the braking unit.
[0038] Based on at least one status information received by at least one control unit, the vehicle status when the electric vehicle is in P gear can be determined, including the status of various components of the vehicle.
[0039] In some embodiments, the body controller 20 is used to control the electric vehicle to activate the vehicle anti-theft function based on vehicle information. The vehicle anti-theft function is used to issue a prompt message after the electric vehicle is touched.
[0040] The vehicle anti-theft function is used to issue an alert message after detecting abnormal behavior or illegal intrusion into an electric vehicle. Sensors on the vehicle can detect whether abnormal behavior or illegal intrusion has occurred. Abnormal behavior can include touching critical components of the vehicle body; this application does not limit the definition of critical components, but includes, but is not limited to, at least one of the following vehicle body parts: door handles, headlights, windows, doors, and hood. Alternatively, abnormal behavior can also include touching any part of the vehicle body. Illegal intrusion refers to the vehicle being opened by improper means, which could be the breaking and opening of a door or a window.
[0041] Optionally, the vehicle anti-theft function can be used to issue a warning message after a key component of the electric vehicle body is touched, or after any part of the electric vehicle body is touched, or after the electric vehicle is illegally entered.
[0042] By issuing a warning message after an electric vehicle is touched, the owner can be notified in time to take appropriate action and avoid further damage to the vehicle.
[0043] In some embodiments, the vehicle controller is used to: control the electric vehicle to activate the vehicle anti-theft function when the vehicle information meets a first condition; wherein the first condition includes: the electric vehicle speed is 0, the electric vehicle power is off, and the electric vehicle gear is in P gear.
[0044] The vehicle controller determines the electric vehicle's speed, power status, and gear position based on at least one status information from at least one control unit. If the electric vehicle's speed, power status, and gear position meet a first condition, the controller activates the vehicle's anti-theft function.
[0045] Based on the gear position information received by the Electronic Transmission System (EGS) from the electric vehicle, it is determined whether the electric vehicle is in Park (P) gear. Based on the vehicle speed information received by the Anti-lock Braking System (ABS), it is determined whether the vehicle speed is 0. Based on the engine status information received by the Engine Control Module (PCM), it is determined whether the electric vehicle's power supply is off. Furthermore, the power supply status received by the Ignition Control Module (ICM) and the pedal status received by the braking unit are used to further verify the accuracy of the above determinations, thus obtaining the final judgment result.
[0046] In some embodiments, vehicle anti-theft features include at least one of the following:
[0047] 1. The vehicle body controller controls the alarm sound on the electric vehicle.
[0048] 2. The body controller controls at least one of the vehicle lights of the electric vehicle to flash. Optionally, the body controller may control only at least one of the parking lights (side marker lights) of the electric vehicle to flash, or the body controller may control only at least one of the headlights (high beam and low beam) of the electric vehicle to flash, or the body controller may control both at least one parking light and at least one headlight of the electric vehicle to flash.
[0049] 3. The vehicle body controller automatically activates the dashcam of the electric vehicle to record. The vehicle body controller can control the dashcam to automatically start recording for a specific period. For example, if the electric vehicle is touched once, the vehicle body controller can control the dashcam to automatically start recording for a first time period, which can be any length such as 5 minutes or 10 minutes. If the electric vehicle is touched more than once but less than or equal to the first touch, the vehicle body controller can control the dashcam to automatically start recording for a second time period, the length of which is longer than the first time period. The first touch can be any number of times such as 3 or 5. If the electric vehicle is touched more than the first touch, the vehicle body controller can control the dashcam to automatically start recording for a third time period, the length of which is longer than the second time period. This application does not limit the specific values of the first, second, and third time periods and the first touch count.
[0050] 4. The vehicle controller sends alarm information to applications interconnected with the electric vehicle. The vehicle controller can control the backend system in the vehicle networking system to send alarm information to applications interconnected with the electric vehicle. The alarm information indicates that the electric vehicle has been touched and may include information about the part of the electric vehicle that was touched, the number of times the electric vehicle was touched, and the processing information taken after the electric vehicle was touched. Among them, the processing information taken after the electric vehicle was touched includes the duration of the alarm sound emitted by the electric vehicle, the flashing information and flashing duration of at least one of the electric vehicle's lights, and the video information recorded by the dashcam.
[0051] In some embodiments, corresponding vehicle anti-theft functions can be activated based on the part of the electric vehicle's body that is touched and the number of times it is touched. For example, after any part of the electric vehicle's body is touched, the body controller can control the electric vehicle to sound an alarm, and the vehicle controller can send an alarm message to an application interconnected with the electric vehicle. After a critical part of the electric vehicle's body is touched, the body controller can control the electric vehicle to sound an alarm, control at least one of the electric vehicle's lights to flash, and the vehicle controller can send an alarm message to an application interconnected with the electric vehicle. After the electric vehicle is illegally accessed, the body controller can control the electric vehicle to sound an alarm, control at least one of the electric vehicle's lights to flash, control the electric vehicle's dashcam to automatically start recording, and the vehicle controller can send an alarm message to an application interconnected with the electric vehicle.
[0052] For example, if the electric vehicle is touched once, the body controller controls the electric vehicle to emit an alarm sound, and the vehicle controller sends an alarm message to an application interconnected with the electric vehicle. If the electric vehicle is touched more than once but less than or equal to the first touch, the body controller controls the electric vehicle to emit an alarm sound, controls at least one of the electric vehicle's lights to flash, and the vehicle controller sends an alarm message to an application interconnected with the electric vehicle. If the electric vehicle is touched more than once continuously, the body controller controls the electric vehicle to emit an alarm sound, controls at least one of the electric vehicle's lights to flash, controls the electric vehicle's dashcam to automatically start recording, and the vehicle controller sends an alarm message to an application interconnected with the electric vehicle.
[0053] For example, when any part of the electric vehicle's body is touched once, the body controller can control the electric vehicle to emit an alarm sound, and the vehicle controller can send an alarm message to an application interconnected with the electric vehicle. When a critical part of the electric vehicle's body is touched more than once but less than or equal to the first touch, the body controller can control the electric vehicle to emit an alarm sound, control at least one of the electric vehicle's lights to flash, and the vehicle controller can send an alarm message to an application interconnected with the electric vehicle. When a critical part of the electric vehicle's body is touched more than the first touch, or when the electric vehicle is illegally accessed, the body controller can control the electric vehicle to emit an alarm sound, control at least one of the electric vehicle's lights to flash, control the electric vehicle's dashcam to automatically start recording, and the vehicle controller can send an alarm message to an application interconnected with the electric vehicle.
[0054] In some embodiments, the body controller 20 is used to control the electric vehicle to activate the parking assist function based on vehicle information, and the parking assist function is used to assist the electric vehicle in completing parking.
[0055] The parking assist function assists the electric vehicle in parking after receiving the driver's parking intention. The driver's parking intention can be determined by the electric vehicle's speed and gear information. If the electric vehicle's speed drops to 0 and the driver shifts to P gear, it indicates that the driver intends to park.
[0056] In some embodiments, the body controller is used to: control the electric vehicle to activate the parking assist function when the vehicle information meets a second condition; wherein the second condition includes: the electric vehicle speed is 0, the electronic parking brake (EPB) system is in the active state, and the electric vehicle gear information is P gear; the parking assist function includes: the body controller controlling at least one control unit to deactivate its corresponding vehicle function.
[0057] The vehicle controller determines the electric vehicle's speed and gear position based on at least one status information from at least one control unit. If the electric vehicle's speed, EPB status information, and gear position information meet a second condition, the controller activates the parking assist function.
[0058] EPB (Electronic Parking Brake) is used to manage the parking function of electric vehicles. It is an electronic parking brake that applies braking force to the rear wheels of the electric vehicle to perform relatively intelligent functions such as automatic clamping, automatic release when starting, automatic holding, re-clamping when the disc is hot / rolling, emergency braking, and rear wheel anti-lock braking. When the driver intends to park, the EPB can be activated, and the EPB will automatically adjust the parking force to prevent the vehicle from rolling.
[0059] The parking assist function can be activated when the electric vehicle's speed is 0, the EPB is on, and the electric vehicle is in P gear. The parking assist function includes the body controller controlling at least one control unit to turn off its corresponding vehicle functions, and the EPB controlling the electric vehicle to prevent it from rolling.
[0060] In some embodiments, the body controller is used to: control the electric vehicle to activate the parking assist function when the vehicle information meets a third condition; wherein the third condition includes: the electric vehicle speed is 0 and the electric vehicle gear information is P gear; the parking assist function includes: the body controller controlling the electronic parking brake system EPB to be in the activated state, and the body controller controlling at least one control unit to deactivate its respective corresponding vehicle function.
[0061] If the driver shifts the electric vehicle to P (Park) while the vehicle speed is 0, the EPB (Electronic Parking Brake) will automatically activate, and the body controller will control at least one control unit to disable its corresponding vehicle function. In other words, the parking assist function includes the body controller controlling the Electronic Parking Brake (EPB) system to be activated, the body controller controlling at least one control unit to disable its corresponding vehicle function, and the EPB preventing the electric vehicle from rolling.
[0062] In some embodiments, the body controller is used to: control the electric vehicle to activate the parking assist function when the vehicle speed is 0 and EPB is activated. The parking assist function includes: the body controller controlling the electric vehicle to be in Park (P) gear, and the body controller controlling at least one control unit to deactivate its corresponding vehicle function. That is, if the driver activates EPB when the electric vehicle speed is 0, the electric vehicle will automatically shift to Park (P) gear, and the body controller will control at least one control unit to deactivate its corresponding vehicle function.
[0063] In some embodiments, the body controller is used to: control the electric vehicle to activate the parking assist function when EPB is activated. The parking assist function includes: the body controller controlling the electric vehicle to reduce its speed to 0, the body controller controlling the electric vehicle to shift to P gear, and the body controller controlling at least one control unit to deactivate its corresponding vehicle function. That is, if the driver activates EPB while the vehicle is in motion, the electric vehicle will activate the parking assist function, the body controller will control the electric vehicle to gradually reduce its speed to 0, the body controller will control the electric vehicle to shift to P gear, and the body controller will control at least one control unit to deactivate its corresponding vehicle function.
[0064] In some embodiments, the body controller 20 is used to control the electric vehicle to activate the vehicle self-check function based on vehicle information. The vehicle self-check function is used to detect the vehicle condition of the electric vehicle.
[0065] The vehicle self-check function is used to determine the condition of an electric vehicle based on vehicle information and to send the results back to the owner.
[0066] In some embodiments, the body controller is used to: control the electric vehicle to activate the vehicle self-test function when the vehicle information meets a fourth condition; wherein the fourth condition includes: the electric vehicle speed is 0 and the electric vehicle gear information is P gear.
[0067] The vehicle controller determines the vehicle speed and gear position of the electric vehicle based on at least one status information from at least one control unit. If the vehicle speed and gear position satisfy a fourth condition, the controller activates the vehicle self-check function.
[0068] In some embodiments, the vehicle self-test function includes: the vehicle controller determining the vehicle status of the electric vehicle based on vehicle information, and sending fault information of the electric vehicle to an application interconnected with the electric vehicle, the fault information being used to describe the vehicle fault of the electric vehicle.
[0069] The fault information includes at least one of the following: obstacle information during the operation of at least one control unit, operating speed of at least one control unit, and fault information of vehicle components of the electric vehicle.
[0070] Obstacle information during the operation of at least one control unit is used to indicate obstacles encountered during the operation of at least one control unit. For example, obstacle information during the operation of EGS is used to indicate faults encountered by EGS in monitoring the gear status of the electric vehicle; obstacle information during the operation of ABS is used to indicate faults encountered by ABS in monitoring the vehicle speed information of the electric vehicle; obstacle information during the operation of ICM is used to indicate faults encountered by ICM in managing the ignition function of the electric vehicle according to the power status of the electric vehicle; obstacle information during the operation of PCM is used to indicate faults encountered by PCM in monitoring the engine status of the electric vehicle; and obstacle information during the operation of the braking unit is used to indicate faults encountered by the braking unit in monitoring the pedal status of the electric vehicle.
[0071] The operating speed of at least one control unit is used to indicate the operating efficiency and functionality of that control unit. For example, if the operating speed of a control unit slows down, it indicates that there is a problem with component wear and tear among the various parts of that control unit.
[0072] Fault information for vehicle components of an electric vehicle is used to indicate wear and tear or damage to various vehicle components. For example, fault information for vehicle components of an electric vehicle includes, but is not limited to, tire leaks leading to insufficient tire pressure, door deformation causing incomplete door closure, damaged lights causing functional limitations, and engine aging causing slower vehicle starting speed, etc. This application does not limit this to such cases.
[0073] The vehicle controller determines the vehicle status of the electric vehicle based on the vehicle information, obtains at least one fault information of the electric vehicle, and sends at least one fault information of the electric vehicle to the application interconnected with the electric vehicle. Each fault information describes a vehicle fault of the electric vehicle, so as to prompt the owner to repair the electric vehicle according to the fault information and restore the vehicle performance of the electric vehicle.
[0074] In some embodiments, the vehicle self-test function further includes: the vehicle controller generating operation prompt information based on the fault information and sending the operation prompt information to the application, the operation prompt information being used to resolve the vehicle fault corresponding to the fault information.
[0075] The vehicle controller obtains at least one corresponding fault resolution operation based on at least one fault information, and generates at least one operation prompt message based on the fault resolution operation corresponding to at least one fault information. Each operation prompt message is used to prompt the vehicle owner to resolve the vehicle fault corresponding to the fault information according to the fault resolution operation contained in the operation prompt message.
[0076] For example, if the fault information includes EPB fault information, the operation prompt information can be used to resolve the vehicle fault corresponding to the EPB. For instance, if the EPB fault information specifically indicates an EPB caliper malfunction, the operation prompt information can advise the vehicle owner to replace the EPB caliper. If the EPB fault information specifically indicates an EPB controller malfunction, the operation prompt information can advise the vehicle owner to check if the EPB controller is faulty.
[0077] The vehicle controller detects the vehicle's condition to obtain fault information and generates corresponding operation prompts based on the fault information. These prompts are then sent to the application, allowing the owner to directly resolve the vehicle faults by following the prompts. This eliminates the need for the owner to search for solutions independently, thus facilitating timely vehicle maintenance and improving operational convenience.
[0078] The technical solution provided in this application connects the vehicle controller to the body controller and at least one control unit via signal lines. This allows the vehicle controller to establish a connection between the body controller and the at least one control unit, combining various vehicle functions to form a control system for the electric vehicle, achieving overall control of all functions. Furthermore, the body controller can acquire at least one status information received by the at least one control unit at any time. Based on at least one status information when the electric vehicle is in Park (P) gear, it can control the electric vehicle to activate anti-theft functions, parking assist functions, and vehicle self-check functions, enriching the vehicle's functions when in Park (P) gear, enhancing the vehicle's intelligence, and improving the convenience for the owner.
[0079] In some embodiments, the vehicle controller receives vehicle information when the electric vehicle is in P gear, and after transmitting the vehicle information to the body controller, the body controller controls the electric vehicle to activate the vehicle anti-theft function only based on the vehicle information.
[0080] In some embodiments, the vehicle controller receives vehicle information when the electric vehicle is in P gear, and after transmitting the vehicle information to the body controller, the body controller controls the electric vehicle to activate the parking assist function only based on the vehicle information.
[0081] In some embodiments, the vehicle controller receives vehicle information when the electric vehicle is in P gear, and after transmitting the vehicle information to the body controller, the body controller controls the electric vehicle to activate the vehicle self-test function only based on the vehicle information.
[0082] In some embodiments, the vehicle controller receives vehicle information when the electric vehicle is in P gear, and after transmitting the vehicle information to the body controller, the body controller controls the electric vehicle to activate the vehicle anti-theft function and parking assist function according to the vehicle information.
[0083] In some embodiments, the vehicle controller receives vehicle information when the electric vehicle is in P gear, and after transmitting the vehicle information to the body controller, the body controller controls the electric vehicle to activate the parking assist function and the vehicle self-check function based on the vehicle information.
[0084] In some embodiments, the vehicle controller receives vehicle information when the electric vehicle is in P gear, and after transmitting the vehicle information to the body controller, the body controller controls the electric vehicle to activate the vehicle anti-theft function and the vehicle self-check function according to the vehicle information.
[0085] In some embodiments, the vehicle controller receives vehicle information when the electric vehicle is in P gear, and after transmitting the vehicle information to the body controller, the body controller controls the electric vehicle to activate the vehicle anti-theft function, parking assist function and vehicle self-check function according to the vehicle information.
[0086] Figure 2 A schematic diagram of the control system of an electric vehicle is shown. The control system of an electric vehicle includes a vehicle controller (VCU), a body controller (BCM), and at least one control unit. The at least one control unit includes a transmission electronic control system (EGS), an anti-lock braking system (ABS), an ignition control module (ICM), an engine control module (PCM), a braking unit, and an electronic parking brake system (EPB).
[0087] When the remote key is turned on, the BCM receives the power status as "on" and sends it to the VCU. The VCU then feeds back the power status to the ICM, which, based on the electric vehicle's power status, initiates the ignition function. The EGS monitors the electric vehicle's gear position. When the driver shifts to P (Park), the EGS sends the gear information to the VCU, which in turn relays it to the BCM. The braking unit monitors the brake pedal position. When the driver depresses the brake pedal, indicating a need for deceleration, the braking unit sends the pedal status to the VCU, which in turn relays it to the BCM. The ABS monitors the vehicle's speed, receiving the actual speed value and sending it to the VCU, which in turn relays it to the BCM. The PCM monitors the engine status, sending it to the VCU, which in turn relays it to the BCM. The EPB monitors the parking status. When the EPB is activated, it sends a parking request to the VCU, requesting control of the parking assist function.
