On-vehicle control device, on-vehicle control method and computer program

An on-vehicle control method of transmitting to a mobile device, in a response to operation of instructing a start of a driving source causing a vehicle to drive, a response request signal requesting a response, and executing authentication processing for authenticating the mobile device based on a response signal from the mobile device in response to the response request signal, and performing start control of the driving source depending on success or failure of authentication by the authentication processing, comprising:

• determining a presence or an absence of unauthorized authentication for the authentication processing;
• detecting an authorized occupant for the vehicle;
• prohibiting the start of the driving source in a case where the presence of unauthorized authentication for the authentication processing is determined;
• permitting the start of the driving source regardless of determination as to the presence or absence of the unauthorized authentication in a case where the occupant is detected;
• not determining as to the presence or absence of the unauthorized authentication in a case where the occupant is detected;
• and
• resuming the determination as to the presence or absence of the unauthorized authentication after a redetermined time has elapsed since detection of the occupant.

A computer program causing an on-vehicle control device to execute processing of transmitting to a mobile device, in response to operation of instructing a start of a driving source causing a vehicle to drive, a response request signal requesting a response in response to operation of instructing a start of a driving source causing a vehicle to drive, and executing authentication processing for authenticating the mobile device based on a response signal from the mobile device in response to the response request signal, and performing start control of the driving source depending on success or failure of authentication by the authentication processing, comprising:

• determining a presence or an absence of unauthorized authentication for the authentication processing;
• detecting an authorized occupant for the vehicle;
• prohibiting the start of the driving source in a case where the presence of unauthorized authentication for the authentication processing is determined;
• permitting the start of the driving source regardless of determination as to the presence or absence of the unauthorized authentication in a case where the occupant is detected;
• not determining as to the presence or absence of the unauthorized authentication in a case where the occupant is detected;
• and
• resuming the determination as to the presence or absence of the unauthorized authentication after a predetermined time has elapsed since detection of the occupant.

An on-vehicle control device including a transmission unit that transmits, in response to operation of instructing a start of a driving source causing a vehicle to drive, to a mobile device a response request signal requesting a response and an authentication unit that authenticates the mobile device based on a response signal from the mobile device in response to the response request signal, and performing start control of the driving source depending on success or failure of authentication by the authentication unit, comprising:

• a determination unit that determines a presence or an absence of unauthorized authentication for the authentication unit;
• a detection unit that detects an authorized occupant for the vehicle;
• a start prohibition unit that prohibits the start of the driving source in a case where the determination unit determines that unauthorized authentication is present for the authentication unit;
• and
• a start permission unit that permits the start of the driving source regardless of determination by the determination unit in a case where the detection unit detects the occupant, wherein the determination unit is configured not to perform the determination as to the presence or absence of the unauthorized authentication in a case where the detection unit detects the occupant and the determination unit resumes the determination as to the presence or absence of the unauthorized authentication in a case where a predetermined operation is accepted after the detection unit detects the occupant.

An on-vehicle control method of transmitting to a mobile device a response request signal requesting a response in response to operation of instructing a start of a driving source causing a vehicle to drive, executing authentication processing for authenticating the mobile device based on a response signal from the mobile device in response to the response request signal, and performing start control of the driving source depending on success or failure of authentication by the authentication processing, comprising:

• determining a presence or an absence of unauthorized authentication for the authentication processing;
• detecting an authorized occupant for the vehicle;
• prohibiting the start of the driving source in a case where the presence of unauthorized authentication for the authentication processing is determined;
• permitting the start of the driving source regardless of determination as to the presence or absence of the unauthorized authentication in a case where the occupant is detected;
• not determining as to the presence or absence of the unauthorized authentication in a case where the occupant is detected;
• and
• resuming the determination as to the presence or absence of the unauthorized authentication when a predetermined operation is accepted after the detection unit detects the occupant.

A computer program causing an on-vehicle control device to execute processing of transmitting to a mobile device a response request signal requesting a response in response to operation of instructing a start of a driving source causing a vehicle to drive, executing authentication processing for authenticating the mobile device based on a response signal from the mobile device in response to the response request signal, and performing start control of the driving source depending on success or failure of authentication by the authentication processing, comprising:

• determining a presence or an absence of unauthorized authentication for the authentication processing;
• detecting an authorized occupant for the vehicle;
• prohibiting the start of the driving source in a case where the presence of unauthorized authentication for the authentication processing is determined;
• permitting the start of the driving source regardless of determination as to the presence or absence of the unauthorized authentication in a case where the occupant is detected;
• not determining as to the presence or absence of the unauthorized authentication in a case where the occupant is detected;
• and
• resuming the determination as to the presence or absence of the unauthorized authentication when a predetermined operation is accepted after the detection unit detects the occupant.
