  • the setting unit 110 may further use the detection result of the driver's line of sight to set the regulation.
  • the setting unit 110 sets a regulation based on detailed information acquired from the position information and map information of the vehicle 1.
  • the setting unit 110 corrects the set regulation using the detection result of the driver's line of sight.
  • the setting unit 110 uses the detection result of the driver's line of sight to identify a direction that is not visible to the driver. Then, the setting unit 110 corrects the regulation to increase the warning sensitivity for the identified direction. In this way, it becomes possible to output a warning that is tailored to the driver's situation.
  • the setting unit 110 may set a rule by further using a sensor (external sensor 30) that detects the situation outside the vehicle.
  • the setting unit 110 sets a rule based on detailed information acquired from the position information of the vehicle 1 and map information.
  • the setting unit 110 further specifies the number of people in the vicinity based on the output of the external sensor 30.
  • the setting unit 110 may further specify attributes of the people (e.g., children) from the results of sensing.
  • the setting unit 110 corrects the set rule based on the result of specifying the number of people and the attributes of the people. Specifically, when a predetermined number or more of children are detected in a parking lot, etc., the rule is corrected to increase the warning sensitivity. In this way, it is possible to output a warning (notification information) according to the surrounding situation.
  • the control device 10 may further have a function of acquiring the driver's feedback information regarding the notification information output regulation and learning the setting value of the regulation suitable for the driver based on the feedback information. For example, the driver inputs positive information indicating that the notification information output regulation is appropriate, or negative information indicating that the notification information output is inappropriate (such as the notification being noisy), using an input device connected via the input/output interface 1050 or the network interface 1060.
  • the setting unit 110 acquires the input information as feedback information and constructs a setting method (algorithm) of the regulation suitable for the driver.
  • the setting unit 110 sets a regulation for outputting voice notification information in a strict expression (e.g., an expression such as "the vehicle will make contact 30 cm behind the vehicle on the right rear"), and the notification output unit 120 performs notification processing in accordance with the regulation. Then, it is assumed that the driver inputs negative feedback information in response to the notification processing in accordance with the regulation. In this case, the setting unit 110 adjusts the algorithm to more actively adopt the regulation for outputting voice notification information in an ambiguous expression (e.g., an expression such as "the vehicle will make contact a little behind the vehicle on the right rear”). This makes it possible to output notification information tailored to the driver.
  • a strict expression e.g., an expression such as "the vehicle will make contact 30 cm behind the vehicle on the right rear”
  • the notification output unit 120 performs notification processing in accordance with the regulation.
  • the driver inputs negative feedback information in response to the notification processing in accordance with the regulation.
  • the setting unit 110 adjusts the algorithm to more actively adopt the regulation for outputting voice notification
