Abstract
The vehicle deceleration control apparatus controls deceleration given to a vehicle according to a distance from a vehicle ahead, which is directly measured or estimated based on an accelerator operating condition, so that the smaller the distance from a vehicle ahead, the greater is an assist deceleration. The vehicle deceleration control apparatus is capable of giving an appropriate deceleration according to traffic conditions.
Claims22
A vehicle deceleration control apparatus, comprising:
- an accelerator operating condition detecting device that detects conditions of an accelerator operated by a driver;
- a deceleration application device that gives deceleration to a vehicle;
- and
- a control device that determines whether the accelerator operation is in a return operation condition based on the results of detection made by the accelerator operating condition detecting device and that, when the accelerator operation is in the return condition and, at the same time, a distance from a vehicle running ahead is evaluated as being long, makes deceleration given to the vehicle by the deceleration application device smaller than when the distance from the vehicle running ahead is short, wherein the control device controls the deceleration given to the vehicle at least based on a depressed position of the accelerator and the deceleration given to the vehicle is different for at least two different depressed positions of the accelerator.

A vehicle deceleration control method, comprising the steps of:
- detecting a condition of an accelerator operated by a driver;
- determining whether the accelerator operating condition detected is in a return operating condition;
- setting deceleration given to a vehicle smaller than when a distance from a vehicle ahead is short, if the accelerator operating condition is determined as being in a return operating condition and if the distance from the vehicle ahead is determined to be long, wherein the set deceleration given to the vehicle is at least based on a depressed position of the accelerator and the set deceleration given to the vehicle is different for at least two different depressed positions of the accelerator;
- and
- giving the set deceleration to the vehicle.
