Abstract
Official abstract text for this publication.
When the operating speed of an accelerator pedal is higher than a given operating speed, a target acceleration as a target output value is multiplied by a gain so that an absolute value of the target acceleration is increased; therefore, a large acceleration requested by the driver can be achieved. The gain by which the target acceleration is multiplied is set to 1 when the target acceleration is about zero, so as to resume a condition where the absolute value of the target acceleration is not increased. Thus, when the control of increasing the absolute value of the target acceleration with the gain is stopped, an elevation change is less likely or unlikely to occur in the actual acceleration. Consequently, a desired acceleration is generated without causing the driver to feel uncomfortable during driving of the vehicle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle control system comprising: a controller that performs running control of a vehicle that includes a drive system by (i) determining a target output value based on a driver's operation of an accelerator member, (ii) determining a second target output value by multiplying the target output value by a gain, and (iii) controlling a driving force to be generated by the drive system based on the second target output value, wherein the controller d…
