Abstract: This disclosure describes example methods and apparatus for automatic identification of performance degradation in a Light Detection and Ranging (LIDAR) device and for providing appropriate precautions in the forms of operation interventions, warnings/alerts, and initiation of maintenance procedures. The performance degradation is derived from various performance indicators obtained by analyzing echo measurement samples detected by the LIDAR device.

Abstract: Disclosed are a method and apparatus for controlling a vehicle speed for autonomous driving, an electronic device and a computer-readable storage medium. The method includes: obtaining a basic vehicle speed control instruction output by a central controller of a target vehicle in real time; generating an ideal speed parameter matching the basic vehicle speed control instruction according to a preset processing delay; generating an additional vehicle speed control instruction to perform vehicle speed control on the target vehicle according to a difference between the ideal speed parameter and a real-time speed parameter of the target vehicle; and returning to perform the operation of generating the ideal speed parameter matching the basic vehicle speed control instruction according to the preset processing delay until the real-time speed parameter of the target vehicle tends to be consistent with the ideal speed parameter.

Abstract: A controller area network (CAN) communication system is provided. The CAN communication system comprises: a CAN bus; at least one electronic control unit (ECU) coupled to the CAN bus; a host module coupled to the CAN bus for controlling the operation of the at least one ECU. The host module comprises: a controller; and at least two adapters coupled between the CAN bus and the controller for communication therebetween. The controller is configured to monitor a communication between a first adapter of the at least two adapters and the CAN bus by a second adapter of the at least two adapters when the controller is communicating with the CAN bus through the first adapter, and to switch its communication with the CAN bus from through the first adapter to through the second adapter when a failure of the communication between the first adapter and the CAN bus is determined.
