Embodiment Construction

[0032] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] Such as figure 1 As shown, the vehicle-mounted sensor rapid diagnosis system based on Telemetry technology of the present invention includes a sensor, a controller, an actuator, a T-BOX terminal, and a user terminal.

[0034] The MCU unit is deployed on the sensor, which is responsible for receiving the initialization information sent by the controller and performing sensor initialization. The initialization settings include synchronizing the sensor reference time, setting the transmission interface and sending cycle. After the sensor is started, the MCU obtains the local signal acquisition physical channel number and acquires the acquisition signal; then sends time stamp, transmission interface, sensor working status, and acquisition signal information, encapsulates them into Telemetry messages, and periodically commu...

Abstract

The invention provides a method and system for realizing rapid diagnosis of a vehicle-mounted sensor based on Telemetry technology. A sensor integrated with an MCU is initialized according to initialization information issued by a controller; the controller encapsulates the acquisition signal and the working state information to a Telemetry message, and periodically reports the message to the controller through a transmission interface; the controller receives the Telemetry message, extracts an acquisition signal of the sensor, analyzes current working state information of the sensor and judges a mode of the sensor; and the controller encapsulates the diagnosis result of the working state of the sensor into the Telemetry message, and sends the Telemetry message to the T-BOX terminal through the transmission interface to dynamically refresh the real-time working state of the sensor. According to the invention, the MCU is deployed in the vehicle sensor to process the Telemetry message, and the working state of the sensor is monitored in real time while data is normally collected and reported, so that the safety of automatic driving is ensured.

Description

technical field [0001] The invention belongs to the technical field of automatic driving, and in particular relates to a method and system for rapid diagnosis of vehicle-mounted sensors based on Telemetry technology. Background technique [0002] Telemetry is a remote high-speed data collection technology from physical or virtual devices. The device periodically and proactively sends the device's input and output interface statistics, time stamps, hardware status data and other information to the collector through the push mode (Push Mode), which provides A more real-time and higher-speed data acquisition function. [0003] For the sensor diagnosis technology involved in the field of automatic driving, the traditional method is mostly through UDS technology, in an offline state, through a specific diagnostic tool to connect to the vehicle ECU, and execute diagnostic commands one by one. Although this traditional sensor diagnosis method can also diagnose whether it is abnor...
