Embodiment Construction

[0037] In the following description and drawings, the invention will be explained in more detail with reference to typical embodiments.

[0038] A first exemplary embodiment of the present invention will be described below with reference to FIGS. 1A to 10 . The exemplary embodiment relates to a vehicle deceleration control device that performs coordinated control of a brake (ie, a braking device) and an automatic transmission.

[0039] This exemplary embodiment provides a deceleration control that combines the advantages of good response and controllability obtained by brake control (automatic brake control) When it detects that the distance between vehicles is equal to or less than a predetermined value according to the distance information between vehicles, it coordinates the two controls.

[0040] According to the structure of this exemplary embodiment, it is assumed that the vehicle is provided with a device that can measure the distance between the host vehicle and the v...

Abstract

In a vehicle deceleration control method, wherein the deceleration control of the vehicle is performed based on the distance between the vehicle and obstacles including the preceding vehicle in front of the vehicle, a target deceleration for decelerating the vehicle is obtained based on the distance a gear or gear ratio is selected as the gear or gear ratio of the vehicle transmission (10) during the shifting operation, said gear or gear ratio will act on the vehicle with a deceleration equal to or less than the target deceleration; the The deceleration control is performed by applying a braking force to the vehicle through a braking device (200) and shifting the transmission (10) of the vehicle into a lower gear or gear ratio through a shift operation.

Description

technical field [0001] The invention relates to a vehicle deceleration control device and method. More particularly, the present invention relates to a deceleration control device and method for a vehicle that decelerates the vehicle by applying a braking force to the vehicle with a brake device and shifting an automatic transmission into a relatively low gear or gear ratio. Deceleration control. Background technique [0002] The deceleration control is often used to perform a downshift operation of the automatic transmission and operate a braking device so that the distance between the target vehicle and the preceding vehicle is not equal to or smaller than a predetermined value. JP(A) 2001-30792 discloses a technique in which when the target deceleration cannot be obtained by completely closing the throttle and downshifting, it can be obtained by completely closing the throttle and operating the automatic transmission without downshifting The target deceleration, this te...
