Shock absorbing vehicle body structure

A shock absorbing vehicle body structure in a vehicle includes a substantially quadrilateral front subsidiary frame comprised of left and right side members extending in a longitudinal direction of a vehicle body and connected at their front and rear ends to each other by a front cross member and a rear cross member. The front subsidiary frame is supported at its four corners on main frames for the vehicle body through rubber mounts and bolts. Upon full-lap collision of the vehicle, the left rear bolt is first broken, whereby the rear end of the left side member is separated from the main frame and then, the right rear bolt is broken, whereby the rear end of the right side member is separated from the main frame. The right and left side members are formed with different rigidities to a longitudinal load applied thereto, which causes the right and left rear bolts to break at different times, or with a time lag therebetween. Such a time lag decreases the peak value of deceleration of the vehicle at a time when the front subsidiary frame is separated from the main frames due to a full-lap collision of the vehicle.

Methods of operating a series hybrid vehicle

The invention is directed toward methods for operating a series hybrid vehicle in a manner that responds to the operator's demand for power output, while maximizing engine efficiency and minimizing disruptions in vehicle drivability. According to principles of the present invention, when the driver of a series hybrid vehicle makes a demand for power output, whether the secondary power source(s) is supplied with secondary energy stored in an energy storage device(s), direct input energy generated by an engine(s), or both, depends on the amount of available secondary energy stored in the vehicle's secondary storage device(s) alone, and in combination with vehicle speed. During the time that the engine is used to generate secondary energy, the power efficiency level at which the engine is operated also depends on the vehicle speed and the amount of available secondary energy stored in the vehicle's secondary storage device alone, and in combination with vehicle speed. Further, in some embodiments, when the engine is not generating secondary energy, the engine is selectively turned off or idled in response to various operating conditions.
