Terminal device, information processing method, and program

Abstract

Even if the terminal device hangs up, the terminal device's operation will be terminated. [Solution] The terminal device comprises a first control unit including one or more first processors, a detector for detecting voltage from a predetermined power source of the vehicle, and a second control unit including one or more second processors. When the voltage changes from a state where it is above a predetermined voltage to a state where it is below a predetermined voltage, the second control unit transmits shutdown instruction information to the first control unit to instruct it to perform a shutdown. If a predetermined first time has elapsed since the shutdown instruction information was transmitted, and the second control unit has not received shutdown completion information from the first control unit indicating that the shutdown has been completed, the second control unit forcibly terminates the operation of the first control unit.

Claims

1. A first control unit including one or more first processors, A detector that detects voltage from a designated power source of the vehicle, A second control unit including one or more second processors, Equipped with, The second control device is When the voltage changes from a state where it is above a predetermined voltage to a state where it is below a predetermined voltage, shutdown instruction information is transmitted to the first control device to instruct it to perform a shutdown. If, after a predetermined first hour has elapsed since the transmission of the shutdown instruction information, shutdown completion information indicating that the shutdown has been completed has not been received from the first control device, the operation of the first control device will be forcibly terminated. Terminal device.

2. The second control device is If it is detected that the voltage has returned to a state of being equal to or greater than the predetermined voltage before the first time has elapsed, reset information is transmitted to the first control unit to cancel the shutdown of the first control unit. The first control device is When the shutdown instruction information is received from the second control device, it is determined whether a predetermined second time has elapsed since the time the shutdown instruction information was received. If the reset information is received before the second time has elapsed, the shutdown operation is canceled. If the second time period has elapsed without receiving the reset information, the shutdown will be performed. The terminal device according to claim 1.

3. The power supply control device further comprises a power supply control device that controls the power supplied to the first control device, The second control device causes the power supply control device to reduce or cut off at least a portion of the power supplied to the first control device from the power supply control device, thereby forcibly terminating the operation of the first control device. The terminal device according to claim 1.

4. The second computer, When the voltage from a predetermined power source of the vehicle changes from a state where it is above a predetermined voltage to a state where it is below a predetermined voltage, shutdown instruction information is transmitted to the first computer instructing it to perform a shutdown. If, after a predetermined first hour has elapsed since the transmission of the shutdown instruction information, shutdown completion information indicating that the shutdown has been completed has not been received from the first computer, the operation of the first computer shall be forcibly terminated. Information processing methods.

5. On the second computer, When the voltage from a predetermined power source of the vehicle changes from a state where it is above a predetermined voltage to a state where it is below a predetermined voltage, shutdown instruction information is transmitted to the first computer instructing it to perform a shutdown. If, after a predetermined first hour has elapsed since the transmission of the shutdown instruction information, shutdown completion information indicating that the shutdown has been completed has not been received from the first computer, the operation of the first computer shall be forcibly terminated. A program to perform a task.

6. A first control unit including one or more first processors, A detector that detects voltage from a designated power source of the vehicle, A second control unit including one or more second processors, Equipped with, The second control device is When the voltage changes from a state where it is above a predetermined voltage to a state where it is below a predetermined voltage, shutdown instruction information is transmitted to the first control device to instruct it to perform a shutdown. When a predetermined first time has elapsed since the transmission of the shutdown instruction information, the operation of the first control device is forcibly terminated. Terminal device.

7. The second computer, When the voltage from a predetermined power source of the vehicle changes from a state where it is above a predetermined voltage to a state where it is below a predetermined voltage, shutdown instruction information is transmitted to the first computer instructing it to perform a shutdown. When a predetermined first time has elapsed since the transmission of the shutdown instruction information, the operation of the first computer is forcibly terminated. Information processing methods.

8. On the second computer, When the voltage from a predetermined power source of the vehicle changes from a state where it is above a predetermined voltage to a state where it is below a predetermined voltage, shutdown instruction information is transmitted to the first computer instructing it to perform a shutdown. When a predetermined first time has elapsed since the transmission of the shutdown instruction information, the operation of the first computer is forcibly terminated. A program to perform a task.
