摘要:
An electronic control apparatus is designed to perform an engine control program in an object-oriented programming manner. A first type message, which does not contain a count value generated as a result of execution of a method of an object, is stored in a message storage unit. At the time that execution of the method is completed, the stored first type message is read out and a method of the object corresponding to the destination of the message is executed. A timer message, which contains a count value generated as a result of execution of the method of the object, is stored in another storage unit. The count value (timer counter) of the timer message in the other storage unit is reduced one by one as a result of the process being performed every predetermined time. When the count value of the timer message reaches 0 in the message storage unit the message is re-stored as a first type message.

An electronic control unit that can execute object-oriented program processing without consuming much memory. When a message is dispatched due to execution of an object method, that message is stored (queued) in an object message holding part. At the point in time when execution of an object method finishes, message delivery processing is executed. If a message has been stored in the object message holding part, the number of queuing messages is counted, the message stored first is read out, and a shift is made to execution of the method of the object that is the output destination of that message. As a result, only messages need to be stored, and the amount of stored information, and thus the amount of memory required to store the information, is small.
摘要:
An engine control program is divided into an application layer and a platform layer. The application layer defines a program which is independent of a hardware and is provided under an object-oriented design. The platform layer defines a program which is dependent on the hardware and is provided under the object-oriented design, and divided into three layers, that is, an upper layer, an intermediate layer and a lower layer. The upper layer, intermediate layer and the lower layer includes a sensor/actuator layer, a device driver layer and a virtual MPU layer, respectively.

A display system and a program for displaying a portion of a range that is obstructed due to the body of a vehicle when viewed from a driver seat is provided. The portion of the range is seamlessly linked to a scene viewed through a windshield. The display system includes an imaging means acquiring an image of an outside of a vehicle including the obstructed portion of the range, a first display means disposed on an instrument panel of the vehicle, and a control means that processes an image acquired by the imaging means. The image displayed on the first display means is seamlessly linked to a scene viewed through the windshield and the processed image is displayed on the first display means.
