An image display apparatus includes a microprocessor configured to perform determining whether a position of a first device is a predetermined position, and controlling image displays on a first display portion provided at the first device and a second display portion provided at a second device in accordance with a determination result. The microprocessor is configured to perform the controlling including controlling image displays on the first display portion and the second display portion so that a predetermined image is displayed on the first display portion before it is determined that the first device is the predetermined position, and the predetermined image is displayed while gradually moving over time from the first display portion to the second display portion when it is determined that the first device is the predetermined position.

Image display apparatus, image display system and image display method

An information transmission apparatus includes: a mode instruction unit configured to instruct a first mode to permit a voice output by the voice output unit or a second mode to prohibit the voice output; an image control unit configured to control a display image of a display unit so as to display an agent image including a face image of an agent; and an output determination unit configured to determine whether or not output of information to the user is necessary. The image control unit controls the display image so as to display, when the output determination unit determines output of information is necessary without being input a voice of an utterance by the user in a state where the second mode is instructed, a second agent image including a second face image.

Information transmission apparatus and information transmission method

In an onboard gateway apparatus, when data is received from one network, the received data is stored in the buffer. The buffer includes a first storage area for storing data in the order of priority of an identifier (ID) attached to the data and a second storage area for storing data in the order in which the data is received. A control means stores the received data in one of the first and second storage areas based on the attached identifier, and sends the data to another network in accordance with the priority of the ID of the data. As to data passing through the first storage area, sending in the order of priority is ensured. As to data passing through the second storage area, sending in the order in which the data is received is ensured.

A memory rewriting system for a vehicle controller is provided. The system comprises a vehicle controller and an external rewriting device. A vehicle controller comprises a rewritable memory storing first security data. The first security data is used to determine whether rewriting to the rewritable memory is permitted. The rewriting device transfers new security data to the vehicle controller. The vehicle controller deletes the first security data and writes the new security data into the rewritable memory. Rewriting the new security data is performed by a program stored in a non-rewritable memory. Thus, the security data that is used to determine whether rewriting to the rewitable memory is permitted is rewritten with the new security data. Therefore, if the existing security data stored in the vehicle controller is invalidated, the security feature of the vehicle can be recovered. The vehicle may includes an anti-theft system. In this case, rewriting to the rewritable memory is permitted if the anti-theft system permits an operation as to the vehicle.

Memory rewriting system for vehicle controller

The rewriting device for rewriting data stored in a memory of a vehicle controller with new data is provided. The rewriting device is capable of communicating with the vehicle controller. When deleting or writing operation on the memory is not being performed, the rewriting device determines that communication between the rewriting device and the vehicle controller is offline if no response from the vehicle controller within a first determination time. When deleting operation or writing operation on the memory is being performed, the determination of offline is prohibited until a second determination time has elapsed. The second determination time is greater than the first determination time. It is preferable that the second determination time for deleting operation is the time necessary to delete the data stored in the memory, and that the second determination time for writing operation is the time necessary to write the new data into the memory.

Rewriting system for rewriting a memory on a vehicle controller

A vehicle controller comprises a first buffer for storing at least one data block, a second buffer for storing at least one data block, and a rewritable non-volatile memory for storing information for controlling a vehicle. The controller receives a data block from an external rewriting device to store it in the first buffer. The data block stored in the first buffer is transferred to the second buffer. The data block stored in the second buffer is written into the memory. When a first data block is written into the memory, a subsequent data block is received. Thus, the time required to rewrite data stored in the nonvolatile memory is reduced.

Vehicle controller for controlling rewriting data in a nonvolatile memory

The rewriting system for rewriting data stored in a memory of a vehicle controller with new data is provided. The rewriting device is capable of communicating with the vehicle controller. The rewriting device enters a waiting state in which there is no exchange of message between the vehicle controller and the rewriting device. The rewriting device is in a waiting state until a predetermined waiting time has elapsed from the time at which a signal for requesting the vehicle controller to delete the data or write the new data is sent, or from the time at which a signal indicative of start of deleting operation of the data or writing operation of the new data is received. Thus, an erroneous determination of offline due to a busy state of the vehicle controller caused by deleting or writing operation is avoided. It is preferable that the predetermined waiting time for deleting operation is the time necessary to delete the data stored in the memory and the predetermined waiting time for writing operation is the time necessary to write the new data into the memory. This enables the waiting time to be optimized in accordance with the specification of the memory.

Rewriting system for vehicle controller

A memory rewriting system for a vehicle controller is provided. The memory rewriting system transfers a first program from a rewriting device to the vehicle to rewrite a second program stored in a memory of the vehicle controller with the first program. The first program is transferred as data blocks. Each of the data blocks includes a program code field, a first address field and a second address field. The program code field contains a partial program code of the first program. The first address field contains a leading address of the memory in which the partial program code is stored. The second address field contains a leading address of the memory in which a following partial program code transferred by another block is to be stored. The data blocks are assembled in the rewriting device. Each data block is may be a fixed length or a variable length. When the data block is transferred to the vehicle controller, a first address in the first address field of the current transferred data block is compared with a second address in the second address field of the preceding transferred data block. If the first address included in the current data block is not equal to the second address included in the preceding data block, it is determined that the current transferred data block is not correct. The vehicle controller requests the rewriting device to retransfer a correct data block that has said second address in the first address field.
