Problems solved by technology

In such a case, if the alternate shifting characteristic still exists, it is still difficult to cause downshifting (kick-down) of the transmission, so it may not be possible to meet the acceleration request of the driver who has performed the stepping operation of the accelerator pedal.

Embodiment Construction

[0079] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. figure 1 It is a block diagram showing a functional configuration of a vehicle including a control device according to an embodiment of the present invention. The vehicle 100 shown in the figure is a four-wheeled vehicle, but is not limited thereto, and may be a two-wheeled vehicle, a three-wheeled vehicle, or the like. In addition, the vehicle 100 may be any one of a gasoline car, a hybrid car, an electric car, and the like.

[0080] Vehicle 100 has a travel control device 101 for controlling the travel of vehicle 100 . Travel control device 101 may also be realized by an electronic control unit (Electronic Control Unit, ECU) which is a computer. The driving control device 101 includes: a processor 102, including a central processing unit (Central Processing Unit, CPU) and the like; and a memory 103, including a read-only memory (Read Only Memory, ROM) or ...

Abstract

A vehicle control device is provided which is capable of properly satisfying an acceleration request from a driver even when the driver performs a step-on operation of an accelerator pedal in the implementation of an ACC mode. The vehicle control device is capable of: a front car follow-up travel mode, in which a driving force and a transmission ratio are controlled based on a first accelerator position (AP1) for an inter-vehicle distance to a preceding vehicle (100) to be a target inter-vehicle distance; and an override mode, in which the driving force and the transmission ratio are controlled based on a second accelerator position (AP2) determined by an operation of an accelerator operator (111) performed by a driver. Compared with a second transmission characteristic (255B) selected inthe override mode, in a first transmission characteristic (255A) selected in the front car follow-up travel mode, a threshold of the accelerator position at which at least downshift of a transmission(TM) occurs is set to a higher value or an amount of change of the transmission ratio along with the downshift of the transmission (TM) is set to a lower value.

Description

technical field [0001] The present invention relates to a control device for a vehicle. Specifically, it relates to a control device for a vehicle capable of adjusting the driving force of the driving source and the gear ratio of the transmission so that the distance from the preceding vehicle becomes the target distance. control. Background technique [0002] Conventionally, there is a control device for controlling the driving force of a driving source of a vehicle and the gear ratio of a transmission. Some of such vehicle control devices include a function of following a preceding vehicle called an adaptive cruise control (Adaptive Cruise Control, ACC) function. In a vehicle control device including such an ACC function, it is possible to automatically control the number of revolutions of the engine and the gear ratio of the transmission so that the vehicle distance to the preceding vehicle becomes the target distance. [0003] In a vehicle including the ACC function as...
