Malfunction detection of shared vehicles

A device for managing a shared vehicle, comprising:

• a processing unit;
• and
• a non-transitory memory coupled to the processing unit and storing instructions thereon, the instructions, when executed by the processing unit, causing the processing unit to perform acts including:
• obtaining first information about a user, the first information indicating a speed of at least one shared vehicle used by the user;
• determining a target vehicle from the at least one shared vehicle based on the first information;
• determining second information about the target vehicle, the second information indicating respective speeds of the target vehicle over multiple travel segments moving at a plurality of time intervals;
• determining a pattern of the second information between the plurality of time intervals;
• and
• detecting an abnormal state of the target vehicle based on the pattern of the second information, the abnormal state indicating that a malfunction occurs in the target vehicle.

A computer program product being tangibly stored on a non-transient machine-readable medium and comprising machine-executable instructions, the instructions, when executed on a device, causing the device to perform acts including:

• obtaining first information about a user, the first information indicating a speed of at least one shared vehicle used by the user;
• determining a target vehicle from the at least one shared vehicle based on the first information;
• determining second information about the target vehicle, the second information indicating respective speeds of the target vehicle over multiple travel segments moving at a plurality of time intervals;
• determining a pattern of the second information between the plurality of time intervals;
• and
• detecting an abnormal state of the target vehicle based on the pattern of the second information, the abnormal state indicating that a malfunction occurs in the target vehicle.
