Vehicle deceleration control device
First Claim
Patent Images
1. A vehicle deceleration control device, comprising:
- a first detection portion for detecting a state of operation when a driver returns an accelerator pedal from a loaded operation range to a no-load operation range, wherein the accelerator pedal is in the no-load operating range when the engine is stopped or when the engine output is at a minimum, and the accelerator pedal is in the loaded operating range when the accelerator is operated to accelerate the vehicle;
a setting portion for setting a braking force to a level equivalent to an engine braking force that is based on the detected state of the operation of the accelerator; and
a control portion for generating, by using a deceleration supplementing portion, the braking force set by the setting portion for compensating for a lack of engine braking effect.

Abstract
A vehicle deceleration control device is provided that can determine an appropriate supplemental braking force when a braking force is applied according to an accelerator operation state. An engine braking-equivalent braking force is varied according to an initial accelerator angle when an accelerator returns and according to an accelerator return speed. That is, the greater the initial accelerator angle is, or the greater the accelerator return speed is, the greater the value to which the engine braking-equivalent braking force is set. It therefore becomes possible to determine the appropriate supplemental braking force that reflects the driver'"'"'s braking intention.
