摘要: An object of the present invention is to minimize a likelihood of the vehicle becoming in an inoperable state even in an event of a program update failure. An in-vehicle device 6 includes: a program storage unit 64 that stores a program; an activation processing unit 65 that activates the program; and an update processing unit 63 that receives an update program 21 and an update reason 22 of the program and updates the program with the update program 21. In a case where the update of the program has failed, the activation processing unit 65 activates the program in an activation mode corresponding to the update reason 22.

摘要: An object of the present invention is to provide a technique that enables a driver to approve transmission of vehicle data to a data center. The information system includes a first device (101-a) mounted in a vehicle, a second device (102-a) operated by a driver, and a third device (103). The first device classifies the vehicle data into the first data and the second data according to preset classification conditions. The first data is data for which an approval operation by the driver is requested. The second data is data for which the approval operation by the driver is not requested. The first device transmits the first data to the second device and transmits the second data to the third device. The second device receives the first data from the first device, and transmits the first data to the third device in response to the approval operation by the driver.

摘要: The present disclosure provides a vehicle control system capable of safely and forcibly controlling a vehicle. A vehicle control system VCS includes a mode setting unit 56 configured to output a forced mode signal upon receiving a forced control instruction from the outside of a vehicle V via a communication device 30, and a forced operation unit 58 configured to output a forced operation signal of forcibly operating the vehicle V to an operation control unit 20. Further, the vehicle control system VCS includes a signal selection unit 59 configured to allow all the operation signals to pass therethrough before receiving the forced mode signal, and block at least a part of the operation signals and allow the forced operation signal instead of the blocked operation signal to pass therethrough after receiving the forced mode signal. The vehicle control system VCS controls an operation of the vehicle V by controlling the operation control unit 20 based on the operation signal or the forced operation signal passing through the signal selection unit 59.

摘要: Function definition information is prepared in a system. The function definition information is information representing a correspondence relationship among a software-based function, a vehicle ID of a vehicle, a hardware configuration for implementing a function, and a software configuration for implementing a function. The system performs a preliminary determination including a determination of a relationship between one or a plurality of user-desired functions constituting a user-desired function group of a user and a hardware configuration of a target vehicle based on the function definition information. For each of the one or more functions specified in the preliminary determination, in order to implement the function in the target vehicle, the system develops a software configuration corresponding to the function in a hardware configuration corresponding to the function in the target vehicle.
