Problems solved by technology

[0005] However, in a vehicle capable of switching driving modes and equipped with a follow-up control function, when follow-up control is performed, the driving mode selected by the driver is not reflected
That is, since the target acceleration calculated in follow-up control is calculated regardless of the driving mode, follow-up control matching the driver's preference cannot be implemented.

Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described in detail using the drawings. figure 1 It is a schematic system configuration diagram of the driving assistance device for a vehicle according to the present embodiment.

[0024] The driving assistance device for a vehicle according to the present embodiment includes a driving assistance ECU 10 . The driving assistance ECU 10 is a device for assisting the driving of the driver, and includes a microcomputer as a main part. The driving assistance ECU 10 of the present embodiment causes the own vehicle to follow the preceding vehicle so that the inter-vehicle distance between the preceding vehicle and the own vehicle is kept within a predetermined range, and, when there is no preceding vehicle, makes the own vehicle Driving at a constant speed set by the driver, thereby assisting the driver in driving. However, in this specification, a microcomputer includes a CPU, storage devices such as ROM and RAM, an...

Abstract

The present invention relates to a driving assistance device for a vehicle capable of implementing follow-up control in accordance with the driver's preference. An acceleration characteristic setting unit (11) sets a following acceleration characteristic (AF) based on a driving mode selected by the driver and a delivery location of the host vehicle. The follow-up acceleration set according to the follow-up acceleration characteristic (AF) corresponds to the engine output characteristic of the driving mode, and the acceleration characteristic for sporty driving is the highest, and the acceleration characteristic for normal HI driving, the acceleration characteristic for normal LO driving, and the acceleration characteristic for energy-saving driving order becomes lower. A following target acceleration calculation unit (13) calculates a following target acceleration (Afollow*) based on a following acceleration characteristic (AF).

Description

technical field [0001] The present invention relates to a driving assistance device for a vehicle that performs follow-up control, which is control for causing a vehicle to follow a preceding vehicle. Background technique [0002] Conventionally, a vehicle is known in which the driving mode can be switched to a plurality of modes such as a normal mode, an energy-saving mode, and a sports mode, as proposed in Patent Document 1. The driving mode determines the output characteristics of the engine with respect to the accelerator operation amount. In the eco mode, the engine output relative to the accelerator operation amount is limited to be smaller than in the normal mode in order to improve fuel efficiency. On the other hand, in the sport mode, in order to improve the responsiveness of the engine output to the accelerator operation, the engine output relative to the accelerator operation amount is set larger than in the normal mode. Such a driving mode can be switched by th...
