Detection system, detection method, and computer-readable storage medium

A detection system comprising:

• a sensor configured to obtain motion information relating to a motion of a human-powered vehicle, and
• electronic controller circuitry configured to determine a technical level of a rider of the human-powered vehicle based on the motion information, wherein
• the technical level includes a first technical level and a second technical level,
• the electronic controller circuitry is configured to select the first technical level in a case where brake information meets a first brake condition and where the motion information meets a first motion condition, and
• the electronic controller circuitry is configured to select the second technical level in a case where the brake information meets a second brake condition and where the motion information meets the first motion condition, the second brake condition being different from the first brake condition.

A detection method comprising:

• obtaining brake information relating to braking of a brake device of a human-powered vehicle using a first sensor;
• obtaining, using a second sensor, vehicle information including at least one of motion information relating to a motion of the human-powered vehicle, and geographical information relating to a geographical location of the human-powered vehicle;
• and
• determining, using electronic controller circuitry, a technical level of a rider of the human-powered vehicle based on the brake information and the vehicle information, wherein
• the technical level includes a first technical level and a second technical level,
• the electronic controller circuitry is configured to select the first technical level in a case where the brake information meets a first brake condition and where the vehicle information meets a first vehicle condition, and
• the electronic controller circuitry is configured to select the second technical level in a case where the brake information meets a second brake condition and where the vehicle information meets the first vehicle condition, the second brake condition being different from the first brake condition.

A non-transitory computer-readable storage medium storing program instructions for causing a detection system to execute a detection method comprising:

• obtaining brake information relating to braking of a brake device of a human-powered vehicle using a first sensor;
• obtaining, using a second sensor, vehicle information including at least one of motion information relating to a motion of the human-powered vehicle, and
• geographical information relating to a geographical location of the human-powered vehicle;
• and
• determining, using electronic controller circuitry, a technical level of a rider of the human-powered vehicle based on the brake information and the vehicle information, wherein
• the technical level includes a first technical level and a second technical level,
• the electronic controller circuitry is configured to select the first technical level in a case where the brake information meets a first brake condition and where the vehicle information meets a first vehicle condition, and
• the electronic controller circuitry is configured to select the second technical level in a case where the brake information meets a second brake condition and where the vehicle information meets the first vehicle condition, the second brake condition being different from the first brake condition.
