Description

Control systems and vehicles

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 21, 2023, with application number 202323512424.X and invention name “Control System and Vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present disclosure generally relates to the field of vehicle technology, and more particularly to a control system and a vehicle. Background Art

[0003] The actual driving and use of a vehicle involves the coordination of a large number of components. Based on this, in related technologies, the vehicle is generally divided into multiple parts according to function and then managed by controllers. In other words, a domain control architecture is used to manage the vehicle's components and signals. For example, a vehicle may include a body domain, a chassis domain, a power domain, a cockpit domain, and an autonomous driving domain. Each domain contains its own controller, namely the body domain controller, chassis domain controller, power domain controller, cockpit domain controller, and autonomous driving domain controller. Through the collaboration and cooperation between the controllers in different domains, the entire vehicle is controlled.

[0004] In related technologies, different controllers need to collect signals to control their own vehicle functions based on the vehicle functions they manage. For example, the body domain controller integrates the basic driving functions of the vehicle body electronics, key functions, lights, doors, windows, and other components.

[0005] However, since the signals that some controllers need to collect are distributed throughout the vehicle, long-distance wiring harnesses are required to connect so many controlled objects. This is especially true for vehicles with longer body lengths, which seriously increases the cost of wiring harnesses and connectors. At the same time, it can cause signal collection to be prone to errors or not be timely enough.

[0006] Public content

[0007] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a control system and a vehicle that can solve the problem that the signals that need to be collected by certain controllers are distributed throughout various locations in the vehicle, which will cause errors or untimely signal collection over long distances. This can greatly improve the safety performance of the vehicle and reduce the cost of wiring harnesses and connectors.

[0008] In a first aspect, a control system is provided, applied to a vehicle, the system comprising a body domain controller and a power domain controller of the vehicle;

[0009] The vehicle body domain controller is connected to a power signal device within a first preset distance range;

[0012] The distance between the power signal device and the power domain controller exceeds the first preset distance range; the distance between the vehicle body signal device and the vehicle body domain controller exceeds the second preset distance range.

In this way, the above-mentioned body domain controller and the power domain controller no longer only collect control signals according to the vehicle functional modules for which they are responsible, but collect control signals of the signal modules within the preset range of each controller according to the principle of nearby collection, thereby ensuring the timeliness and accuracy of signal collection, greatly reducing the frequency of problems such as missed signals, and thus greatly improving the safety performance of the vehicle.

[0019] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Other features, objects and advantages of the present application will become more apparent upon reading the detailed description of non-limiting embodiments made with reference to the following drawings:

[0021] FIG1 is one of the schematic diagrams of a control system provided in an embodiment of the present application.

[0022] FIG2 is a second schematic diagram of a control system provided in an embodiment of the present application. DETAILED DESCRIPTION

[0023] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant application and are not intended to limit the application. It should also be noted that, for ease of description, only the portions relevant to the application are shown in the accompanying drawings.

[0024] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0025] The following describes the usage scenarios of this application:

[0026] In related technologies, a vehicle is generally divided into multiple parts, each of which is managed by a controller. Different controllers have different functions. Specifically, the body domain controller is used to control load drive and coordinate the activation of vehicle electrical appliances, etc.; the chassis domain controller is used to control vehicle driving-related systems, including the transmission system, driving system, steering system and electronic handbrake system; the power domain controller is used to collect accelerator pedal and brake pedal signals, etc.

[0027] Specifically, the body domain controller is used to control the vehicle system's integrated lighting, wiper and washer, central door lock, gateway, window control, PEPS (Passive Entry and Passive Start) smart key, low-frequency antenna, etc.

[0028] In related technologies, the power domain controller is used to control the vehicle's movement and stopping. Based on this, the power domain controller directly collects the braking signal generated by the brake pedal and the driving signal generated by the accelerator pedal, while the chassis domain controller collects the signal generated by the electronic parking brake.

[0029] However, this process presents several challenges. Because the CAN bus handles all signal transmission, it can easily lead to signal errors and inability to communicate with the power domain controller. Furthermore, the accelerator pedal (which generates the throttle signal) and the brake pedal (which generates the braking signal) are located at the front of the vehicle, while the power domain controller is located at the rear. This makes signal acquisition difficult, especially for large vehicles like trucks.

[0030] Based on this, the present application proposes a control system and a vehicle that can solve the problem that the signals that some controllers need to collect are spread across various locations in the vehicle, which will cause long-distance signal collection to be prone to errors or not timely enough. By collecting cross-domain signals nearby, the safety performance of the vehicle can be greatly improved and the cost of wiring harnesses and connectors can be reduced.

[0031] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] Figures 1 and 2 are schematic diagrams of a control system according to an embodiment of the present application. The method may be performed by the vehicle described above. As shown in Figures 1 and 2, the control system includes: a body domain controller and a power domain controller of the vehicle described above.

[0033] In an embodiment of the present application, the above-mentioned control system includes the body domain controller and the power domain controller of the above-mentioned vehicle.

[0034] It can be understood that the above-mentioned body domain controller and power domain controller can refer to the above description and will not be repeated here.

[0035] In an embodiment of the present application, the above-mentioned vehicle body domain controller is connected to a power signal device within a first preset distance range.

[0036] In an embodiment of the present application, the power domain controller is connected to a vehicle body signal device within a second preset distance range.

[0037] In an embodiment of the present application, the vehicle body domain controller and the power domain controller are connected via a first communication bus to transmit signals of the power signal device and the vehicle body signal device to each other.

[0038] The distance between the power signal device and the power domain controller exceeds the first preset distance range; the distance between the vehicle body signal device and the vehicle body domain controller exceeds the second preset distance range.

[0039] Exemplarily, the first preset range may be preset by the control system or may be customized by the user.

[0040] It can be understood that the distance between the power signal device and the vehicle body domain controller is within the first preset range, which is used to indicate that the distance between the power signal device and the vehicle body domain controller is relatively close.

[0041] Furthermore, according to the above content, when the vehicle body domain controller collects signals from a signal device that is far away from it, it is easy to have problems with signal collection errors or untimely signal collection. Therefore, it should collect signals from signal devices that are closer to it, that is, signals within the first preset range, to achieve cross-domain signal collection nearby.

[0042] In an embodiment of the present application, the power signal device includes at least one signal sub-device, that is, a signal sub-device controlled by a power domain controller.

[0043] In an embodiment of the present application, the power signal device may be used to characterize a plurality of power signal sub-devices with different functions in the vehicle within a first preset range.

[0044] Exemplarily, the body domain controller is used to collect the power signal of the power signal device in the vehicle and send the power signal to the power domain controller through a communication connection with the power domain controller.

[0045] Exemplarily, the power domain controller is configured to receive the power signal through a communication connection with the body domain controller and control the driving state and braking state of the vehicle according to the power signal.

[0046] Optionally, in an embodiment of the present application, the body domain controller is located in the front area of ​​the vehicle.

[0047] Optionally, in an embodiment of the present application, the power signal device specifically includes at least one of an accelerator pedal device and a brake pedal device.

[0048] In an embodiment of the present application, the above-mentioned power signal includes at least one of the following: the driving start signal of the vehicle, the driving stop signal of the vehicle, the driving abnormality signal of the vehicle, the braking start signal of the vehicle, the braking stop signal of the vehicle and the braking abnormality signal of the vehicle.

[0049] It is understood that the driving start signal and the driving stop signal can be represented by the angle of the accelerator pedal, and correspondingly, the braking start signal and the braking stop signal can be represented by the angle of the brake pedal. Furthermore, the vehicle braking stop signal can also include a signal related to the electronic parking brake.

[0050] Based on this, further, the above-mentioned power signal may include at least one of the following: the angle signal of the accelerator pedal, the fault signal of the accelerator pedal; the above-mentioned brake signal may include at least one of the following: the angle signal of the brake pedal, the fault signal of the brake pedal, the electronic handbrake trigger signal, the electronic handbrake closing signal, and the electronic handbrake abnormal signal.

[0051] In an embodiment of the present application, the at least one signal submodule included in the above-mentioned power signal device includes: a signal submodule controlled by a vehicle body domain controller and / or a signal submodule controlled by a power domain controller, which is not limited in this embodiment of the present application.

[0052] Exemplarily, in the case where at least one signal sub-module included in the above-mentioned power signal device includes a signal sub-device controlled by a power domain controller, according to the principle of proximity collection, the signal of the signal sub-device is collected by the body domain controller, and then sent by the body domain controller to the power domain controller, and finally the power domain controller receives the signal of the signal sub-device and executes the signal of the signal sub-device.

[0053] Exemplarily, the second preset range may be preset by the control system or may be customized by the user.

[0054] It can be understood that the distance between the vehicle body signal device and the power domain controller is within the second preset range, which is used to indicate that the distance between the vehicle body signal device and the power domain controller is relatively close.

[0055] Furthermore, according to the foregoing content, when the power domain controller collects signals from a signal device that is far away from it, it is easy to have problems with signal collection errors or untimely signal collection. Therefore, it should collect signals from signal devices that are closer to it, that is, signals within the second preset range.

[0056] In the embodiment of the present application, the vehicle body signal device includes at least one signal submodule.

[0057] In the embodiment of the present application, the vehicle body signal device may be used to represent a plurality of signal sub-devices with different functions in the vehicle within the second preset range.

[0058] Optionally, in an embodiment of the present application, the body domain controller is located in the front area of ​​the vehicle, and correspondingly, the power domain controller can be set in the rear area of ​​the vehicle.

[0059] It is understandable that, from the above content, the body domain controller and the power domain controller are located in different positions in the vehicle (generally, the body domain controller is located at the front of the vehicle, and the power domain controller is located at the rear of the vehicle). At the same time, the controller control signal devices in the vehicle are divided according to function. Therefore, the body domain controller located at the front of the vehicle may need to collect and control the signals of the signal device located at the rear of the vehicle, while the power domain controller located at the rear of the vehicle may need to collect and control the signals of the signal device located at the front of the vehicle. This will bring about the problem of untimely or missed signal collection and control, and at the same time, greatly reduce the cost of wiring harnesses and connectors caused by long-distance wiring harness transmission. Therefore, in the embodiment of the present application, according to the principle of nearby collection, a signal device that is closer to the body domain controller will be planned, and a signal device that is closer to the power domain controller will be planned. Please refer to the following description of the power domain controller and the body domain controller for details.

[0060] First, the planning method for the signal device controlled by the power domain controller is as follows:

[0061] Optionally, in an embodiment of the present application, the above-mentioned power domain controller is used to collect the body domain control signal of the body signal device located within the above-mentioned second preset range of the location of the above-mentioned power domain controller, and control the body part according to the above-mentioned body domain control signal.

[0062] Exemplarily, the distance between the vehicle body signal device and the vehicle body domain controller exceeds the second preset range.

[0063] For example, the second preset range can refer to the above description and will not be repeated here.

[0064] It can be understood that the function of the above-mentioned body signal device belongs to the body domain control module, but since the distance between the body signal device and the body domain controller exceeds the second preset range, that is, the body signal device is closer to the power domain controller, the body domain control signal of the body signal device is collected by the power domain controller and controlled by the power domain controller.

[0065] It should be noted that the above-mentioned body domain control signal is a signal that can be directly controlled, that is, the above-mentioned body domain control signal does not necessarily require the hardware support of the body domain controller to be controlled, that is, it is a signal that can be executed by any controller after collection. Therefore, the power domain controller can control the above-mentioned body domain control signal.

[0066] In one example, when the body domain control signal includes a taillight signal within a second preset range of the power domain controller, the power domain controller is further used to collect the taillight signal of the taillight and control the taillight according to the taillight signal.

[0067] Optionally, in an embodiment of the present application, the vehicle body signal device includes at least one of a lamp signal device, a radar signal device, and a camera signal device in the rear area of ​​the vehicle.

[0068] Exemplarily, the above-mentioned taillights include brake lights, position lights, rear turn signals, etc., which are located at the rear end of the vehicle body.

[0069] It is understandable that the aforementioned taillights are located at the rear of the vehicle and are functionally part of the vehicle body. However, they are relatively close to the power domain controller located at the rear (and correspondingly, farther from the body domain controller located at the front). Furthermore, the taillight signals from the taillights are controlled objects and do not need to be actively transmitted to the power domain controller. Therefore, according to the principle of local acquisition, the power domain controller can directly control the taillights directly after acquiring the taillight signals.

[0070] Second, the planning method for the signal device controlled by the vehicle body domain controller is as follows:

[0071] Optionally, in an embodiment of the present application, the above-mentioned body domain controller is used to collect the power domain control signal of the power signal device located within the above-mentioned first preset range of the location of the body domain controller, and control the vehicle power part according to the above-mentioned power domain control signal.

[0072] Exemplarily, the distance between the power signal device and the power domain controller exceeds the first preset range.

[0073] It can be understood that the function of the above-mentioned power signal device belongs to the power domain control module, but since the distance between the first power domain control module and the power domain controller exceeds the first preset range, that is, the power signal device is closer to the body domain controller, the power domain control signal of the power signal device is collected by the body domain controller and controlled by the body domain controller.

[0074] It should be noted that the above-mentioned power domain control signal is a signal that can be directly controlled, that is, the above-mentioned power domain control signal does not necessarily require the hardware support of the power domain controller to be controlled, that is, it is a signal that can be executed by any controller after collection. Therefore, the body domain controller can control the above-mentioned power domain control signal.

[0075] In one example, when the power domain control signal includes a front vehicle radar signal within the first preset range of the body domain controller, the body domain controller is further used to collect the front vehicle radar signal of the front vehicle radar module in the vehicle and control the front vehicle radar according to the front vehicle radar signal.

[0076] Exemplarily, the above-mentioned front vehicle radar modules are respectively located at the front end of the vehicle body. The front vehicle radar modules have built-in radar signal receiving modules and transmitting modules, and measure distance and vehicle speed through reflected echoes.

[0077] It is understandable that the aforementioned front vehicle radar module is located at the front of the vehicle and functionally belongs to the power domain. However, this front vehicle radar module is closer to the body domain controller located at the front of the vehicle (and correspondingly farther from the power domain controller located at the rear of the vehicle). Furthermore, the front vehicle radar signal from the front vehicle radar module is the controlled object and does not need to be actively transmitted to the body domain controller. Therefore, according to the principle of local acquisition, the body domain controller can directly control the front vehicle radar module after acquiring the front vehicle radar signal.

[0078] In an embodiment of the present application, the at least one signal submodule included in the above-mentioned vehicle body signal device includes: a signal submodule controlled by a vehicle body domain controller and / or a signal subdevice controlled by a power domain controller, which is not limited in this embodiment of the present application.

[0079] In an embodiment of the present application, the body domain controller is further configured to receive the power sub-control signal sent by the power domain controller.

[0080] Exemplarily, when at least one signal submodule included in the above-mentioned vehicle body signal device includes a signal submodule controlled by a vehicle body domain controller, according to the principle of proximity acquisition, the signal of the signal submodule is collected by the power domain controller, and then sent by the power domain controller to the vehicle body domain controller, and finally the vehicle body domain controller receives the signal of the signal submodule and executes the signal of the signal submodule.

[0081] In an embodiment of the present application, the above-mentioned first communication bus may be a CAN bus.

[0082] Exemplarily, the first communication bus includes a serial communication protocol bus of the vehicle.

[0083] In the present application, a control system applied to a vehicle is disclosed, and the above-mentioned control system includes a body domain controller and a power domain controller of the above-mentioned vehicle. The above-mentioned body domain controller is connected to the power signal device within a first preset distance range, and the above-mentioned power domain controller is connected to the body signal device within a second preset distance range. The above-mentioned body domain controller and the above-mentioned power domain controller are connected via a first communication bus so as to transmit signals of the above-mentioned power signal device and the above-mentioned body signal device to each other (wherein, the distance between the power signal device and the power domain controller exceeds the first preset distance range, and at the same time, the distance between the body signal device and the body domain controller exceeds the second preset distance range). In this way, the above-mentioned body domain controller and the power domain controller no longer only collect control signals according to the vehicle functional modules for which they are responsible, but collect control signals of signal modules within the preset range of each controller according to the principle of nearest collection, thereby ensuring the timeliness and accuracy of signal collection, greatly reducing the frequency of problems such as missed signals, and thus greatly improving the safety performance of the vehicle.

[0084] Optionally, in an embodiment of the present application, the body domain controller and the power domain controller are further connected via a protocol transmission channel.

[0085] Exemplarily, the above-mentioned protocol transmission channel is used to transmit the power signal device signal.

[0086] Optionally, in an embodiment of the present application, the vehicle body domain controller and the power domain controller are further connected via a second communication bus to transmit the power signal device signal.

[0087] Exemplarily, the second communication bus may be a point-to-point CAN dedicated line between the vehicle body domain controller and the power domain controller, and the CAN dedicated line belongs to the driving behavior network CAN.

[0088] It is understandable that the second communication bus is specifically used to transmit signals between the power domain controller and the body domain controller. It should be noted that, as mentioned above, vehicles with a domain control architecture (i.e., vehicles with multiple domain controls) generally have a CAN bus for transmitting signals between different domains, while the CAN dedicated line of the protocol transmission channel is a separate CAN dedicated line that is dedicated to the connection between the body domain controller and the power domain controller.

[0089] Furthermore, the above-mentioned CAN dedicated line can be implemented by modifying the relevant protocol algorithm of the vehicle CAN bus without changing the vehicle hardware.

[0090] In another example, the protocol transmission channel may be a vehicle communication protocol transmission bus (CAN bus).

[0091] It can be understood that the above-mentioned vehicle segment communication protocol transmission bus is used to execute the signal acquisition process and transmission process corresponding to each control domain of the above-mentioned vehicle.

[0092] Optionally, in this embodiment of the present application, the vehicle body domain controller and the power domain controller are further connected via a hardwire, wherein the hardwire is used to transmit power signal device signals based on pulse-width modulated signals. The pulse-width modulated signals and the power signals transmitted by the first and / or second communication buses can also be mutually verified.

[0093] In an example, the power control signal transmitted based on the pulse width modulation signal may be a first pulse width modulation signal (Pulse Width Modulation, PWM signal), that is, the first pulse width modulation signal is used to indicate the power control signal.

[0094] It can be understood from the above content that the power control signal is divided into multiple different power control signals, and different power control signals correspond to different first PWM signals. Therefore, different power control signals can be represented by different PWM signals.

[0095] In an example, the first PWM signal may be a duty cycle signal with a specific amplitude and a specific frequency. For example, the first PWM signal may be a duty cycle signal with an amplitude of 12V and a frequency of 1kHz.

[0096] Optionally, in an embodiment of the present application, the above-mentioned control system also includes a chassis domain controller arranged in the middle area of ​​the above-mentioned vehicle.

[0097] Exemplarily, the chassis domain controller and the body domain controller are connected via the first communication bus.

[0098] Optionally, in an embodiment of the present application, the vehicle body domain controller is further hard-wired to an electrical park brake (EPB) device within a third preset distance range.

[0099] Exemplarily, the parking signal device includes an electronic parking brake system.

[0100] It can be understood that the electronic handbrake system is directly connected to the vehicle body domain controller through a hard line, and the power signal device of the vehicle body domain controller transmits the signal of the above-mentioned electronic handbrake system from the hard line to the power signal device.

[0101] Optionally, the control system further includes a first transceiver and a second transceiver.

[0102] Exemplarily, the first transceiver is used to transmit the power signal of the vehicle body domain controller, and the second transceiver is used to transmit the control signal of the power domain controller.

[0103] Exemplarily, the first transceiver and the second transceiver are respectively connected to two sides of the communication connection.

[0104] It can be understood that the first transceiver and the second transceiver can be used to transmit signals on both sides of the communication connection.

[0105] In this way, since the protocol transmission channel does not cause excessive increase in hardware costs, safer vehicle control and vehicle driving can be achieved in a very low-cost manner.

[0106] The embodiment of the present application further provides a vehicle, which includes the above-mentioned control system, and the above-mentioned control system includes a body domain controller and a power domain controller of the above-mentioned vehicle;

[0107] The vehicle body domain controller is used to collect a first control signal from a power signal device within a first preset range of the vehicle body domain controller, and the distance between the power signal device and the power domain controller exceeds the first preset range;

[0108] The above-mentioned power domain controller is used to collect the second control signal of the vehicle body signal device within a second preset range of the location of the above-mentioned power domain controller, and the distance between the above-mentioned vehicle body signal device and the above-mentioned vehicle body domain exceeds the above-mentioned second preset range.
