Description

Technical Field

[0001] This utility model relates to the field of automotive electronics technology, and more specifically, to a novel yaw rate sensor. Background Technology

[0002] Electronic Stability Program (ESP) is a vehicle's active safety system, also known as a dynamic driving control system. Simply put, it's an anti-skid system. See the appendix for details on its components. Figure 1 While the vehicle is in motion, ESP constantly uses the steering wheel angular velocity sensor and throttle sensor to determine the driver's intentions. At the same time, it monitors the vehicle's driving status using the yaw rate sensor and lateral acceleration sensor. If it detects that the vehicle's status is unstable, it can control the braking system, drive management system, and transmission management system to compensate for vehicle slippage in a targeted manner.

[0003] Intelligent driving control systems require the acquisition of yaw rate sensor signals to monitor vehicle attitude in real time, thus forming a closed-loop vehicle attitude control system. On the other hand, in-vehicle central control screens are becoming increasingly intelligent, displaying vehicle attitude to the driver through virtual vehicle displays. The yaw rate sensor can exist independently and transmit signals via CAN, or it can be integrated into the ESP controller, which sends the yaw rate signal via CAN. Both methods present a problem: the CAN signal is transmitted in the vehicle's powertrain CAN network, while the central control screen receives information in the vehicle's CAN network. The yaw rate sensor signal needs to be relayed through a gateway before being sent to the central control screen. This results in a time delay in the yaw rate sensor signal received by the central control screen, causing the virtual vehicle's attitude to differ from the actual vehicle attitude. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a novel yaw rate sensor. By adding a first UWB module to the original yaw rate sensor, it can establish a connection with the second UWB module of the central control screen controller through the UWB protocol to transmit information, so that the posture of the virtual car displayed on the central control screen will be consistent with the actual vehicle posture.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A novel yaw rate sensor includes a yaw rate sensing unit, a first UWB module, a power supply module, a second UWB module, a central control screen controller, a monitoring module, and a storage module. The first UWB module communicates with the yaw rate sensing unit, the monitoring module, and the second UWB module. The power supply module provides power to the yaw rate sensing unit, the first UWB module, and the monitoring module. The second UWB module communicates with the central control screen controller and the storage module.

[0007] Preferably, the monitoring module includes a visual camera capable of monitoring the vehicle's tilt in real time when it turns.

[0008] Preferably, there is a signal connection between the storage module and the central control screen controller.

[0009] Preferably, the yaw rate sensing unit includes a sensor, an A / D converter, a microcontroller, and an EEPROM connected in sequence.

[0010] Preferably, the communication method between the first UWB module and the yaw rate sensing unit, the second UWB module and the monitoring module is serial communication.

[0011] Preferably, the second UWB module communicates with the central control screen controller and the storage module via serial communication.

[0012] Preferably, the first UWB module communicates with the microcontroller of the yaw rate sensing unit.

[0013] The beneficial effects of this utility model are:

[0014] This invention adds a first UWB module to the existing yaw rate sensor, which can establish a connection with the second UWB module of the central control screen controller via the UWB protocol to transmit information. It also includes a monitoring module that can collect vehicle roll information and a storage module that can store yaw rate information. This allows the virtual vehicle posture displayed on the central control screen to be consistent with the actual vehicle posture when the two sets of information are compared, and historical information can be retrieved and viewed at any time. Attached Figure Description

[0015] Figure 1 This is a structural schematic diagram of a specific embodiment of the present utility model. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 As shown, a novel yaw rate sensor includes a yaw rate sensing unit, a first UWB module, a power supply module, a second UWB module, a central control screen controller, a monitoring module, and a storage module. The first UWB module communicates with the yaw rate sensing unit, the monitoring module, and the second UWB module. The power supply module provides power to the yaw rate sensing unit, the first UWB module, and the monitoring module. The second UWB module communicates with the central control screen controller and the storage module. The monitoring module includes a visual camera capable of real-time monitoring of vehicle tilt during steering. The storage module and the central control screen controller are connected by a signal connection. The yaw rate sensing unit includes a sensor, an A / D converter, a microcontroller, and an EEPROM connected in sequence. The first UWB module communicates with the yaw rate sensing unit, the second UWB module, and the monitoring module via serial communication. The second UWB module communicates with the central control screen controller and the storage module via serial communication. The first UWB module communicates with the microcontroller of the yaw rate sensing unit.

[0018] By adopting the above technical solution, in this utility model, the sensor can be analog or digital, responsible for collecting on-site data and sending it to the microprocessor. If the sensor collects analog signals, A / D conversion and some signal processing are required. The microprocessor is the core device, responsible for processing the data transmitted from the sensor and controlling it. The sensor does not exist in isolation; it can be indirectly controlled through the UWB module of the central control screen. In this case, the microprocessor needs to control the first UWB module to communicate with the second UWB module of the central control screen controller, sending the sensor data to the central control screen controller and receiving control information from the central control screen controller.

[0019] Furthermore, by setting up a monitoring module—specifically, a visual camera that monitors the vehicle's tilt in real time during steering—it can capture and collect information on the vehicle's yaw angle in real time. This information is then fed back to a second UWB module on the central control screen controller via a first UWB module. This allows for comparison of vehicle attitude information from the monitoring module and the yaw rate sensor unit, enabling appropriate corrections. The vehicle attitude information can be stored in a storage module and retrieved and viewed at any time on the central control screen controller, facilitating the observation of historical vehicle attitude information.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
