A vehicle engine control device includes an operation-degree detecting device for detecting the degree of each operation of a manually operated member effected to control the output of the engine via a throttle valve actuator and a throttle valve; a target acceleration setting device for generating a target acceleration signal corresponding to the degree of the operation of the manually operated member; an acceleration detecting device for detecting each operative acceleration of the vehicle; and a control signal outputting device for comparing the target acceleration signal, which has been generated from the target acceleration setting device, with the detection results from the accelerating detecting device and then outputting a control signal to the actuator so as to control the degree to which the throttle valve is opened in such a way that the operative acceleration of the vehicle is controlled to the target acceleration.

Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
