Provided are a program updating device, a program updating system and a program updating method which safely and reliably implement a program update without imposing a burden on a user. The program updating device is provided with a communication unit for transmitting/receiving information to/from an in-vehicle device operated on the basis of a software program, and transmits update information onthe software program from the communication unit to execute an update process. The program updating device is provided with: a determination unit which determines whether an operation switch of a vehicle has been switched from an on-state to an off-state; a state control unit which instructs to transition to a traveling prohibition state and maintain an ignition-on state, when the operation switch is determined to have been switched to the off-state; and an update processing unit which starts an update process on the basis of the update information, after confirming that the vehicle has transitioned to the traveling prohibition state and the ignition-on state is maintained, according to the instruction from the state control unit.
本发明提供一种程序更新装置、程序更新系统及程序更新方法,不会对用户造成负担,安全且可靠地实现程序更新的执行。程序更新装置具备在与基于软件程序进行动作的车载装置之间收发信息的通信部,并从该通信部发送针对所述软件程序的更新信息而执行更新处理,其中,程序更新装置具备:判别部,判别车辆的操作开关是否已从接通状态向断开状态切换;状态控制部,在判别为已向断开状态切换的情况下,指示向行驶禁止状态的转移及点火启动状态的维持;及更新处理部,在确认了根据来自该状态控制部的指示而所述车辆已向行驶禁止状态转移且维持了点火启动状态之后,基于所述更新信息开始更新处理。
