Abstract
Official abstract text for this publication.
An ECU includes a collision determination unit, a condition determination unit, and an output suppression unit. The collision determination unit monitors an acceleration detected by a collision sensor, and determines that a vehicle collision has occurred when the acceleration is greater than a predetermined value. The condition determination unit determines whether or not a vehicular speed absolute value is smaller than a threshold vehicular speed in a determination period lasting from the determination of collision for a predetermined time. The output suppression unit suppresses an output of a vehicle driving force when the vehicular speed absolute value is smaller than the threshold vehicular speed in the determination period.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle comprising: a driving unit configured to generate a driving force for the vehicle; and a control unit configured to perform a suppression control to suppress said driving force greater in a case where said vehicle has encountered a collision and a vehicular speed maintaining control for automatically maintaining the vehicular speed at a predetermined value is performed than a case where said vehicle has encountered a collision and said vehicular speed maintaining control is not performed, wherein the control unit increases said driving force in accordance with an amount that an accelerator pedal is manipulated while said driving force is suppressed greater than zero and the case where said vehicle has encountered the collision and said vehicular speed maintaining control is not performed. 2. The vehicle according to claim 1 , wherein said control unit performs said suppression control in a case where said vehicular speed is lower than a threshold vehicular speed at a time when said vehicle has encountered a collision regardless of whether or not said vehicular speed maintaining control is being performed. 3. The vehicle according to claim 1 , wherein the control unit deactivates said suppression control when a predetermined time period elapses after the suppression control is activated, and decreases a suppression amount gradually when said suppression control is deactivated and the vehicle returns to normal control.
