Failure detection method and failure detection module for actuator of intelligent driving vehicle, and vehicle-mounted equipment

Abstract

The embodiment of the invention relates to a failure detection method and failure detection module for an actuator of an intelligent driving vehicle, and vehicle-mounted equipment. The method comprises the following steps: obtaining expected control information and actual vehicle state information; determining a first speed mode based on the expected control information; determining a second speedmode based on the actual vehicle state information; and detecting the failed actuator based on the first speed mode and the second speed mode. According to the method, the module, and the vehicle-mounted equipment, the failed actuator is detected through the first speed mode and the second speed mode, active detection for the actuator is realized, the failed actuator is found in time, and then adriver is reminded to take over control right in time and take corresponding actions to ensure driving safety.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of intelligent driving, and specifically relate to a failure detection method, module, vehicle-mounted device, and non-transitory computer-readable storage medium of an actuator of an intelligent driving vehicle. Background technique [0002] The underlying actuators of intelligent driving vehicles can be divided into three types according to different functions: drive system, braking system and steering system. Under normal circumstances, the controllers of the driving system, braking system and steering system each report whether the system is faulty and the corresponding fault information (fault code), inform the upper intelligent driving system, and the intelligent driving system then reminds the driver to take over control And take corresponding actions to ensure driving safety. [0003] However, when some faults occur, the underlying controller may not report the corresponding f...

Problems solved by technology

[0003] However, when some faults occur, the underlying controller may not report the corresponding fault information in time, or due to other reasons, the upper intelligent driving system cannot obtain the fault information reported by the underlying controller in time, so it cannot take corresponding actions in time, resulting in driving hazard

[0004] For example, the intelligent driving system issues a braking command, but the braking system does not work or the braking force is insufficient; The system or steering system has failed, if the driver cannot be reminded in time, it will cause an accident of the intelligent driving vehicle
