no. 1 Embodiment approach ＞

[0020] refer to Figure 1 ~ Figure 4 A first embodiment of the driving assistance device will be described.

[0021] (structure)

[0022] refer to figure 1 The configuration of the driving assistance device according to the first embodiment will be described. figure 1 It is a block diagram showing the configuration of the driving assistance device according to the first embodiment.

[0023] exist figure 1 Among them, the driving assistance device 100 is mounted on the vehicle 1 . The driving assistance device 100 is configured to be able to perform follow-up control in which the vehicle 1 is caused to travel ahead of the vehicle 1 in the path ahead (for example, in the same lane as the vehicle 1 is traveling). Acceleration and deceleration are controlled in such a manner as to maintain a predetermined inter-vehicle distance during travel, and when the preceding vehicle stops, acceleration and deceleration are performed in such a manner that the vehicle 1 stops at a predet...

Abstract

The present disclosure provides a driving assistance apparatus configured to provide the assistance associated with the following distance while preventing the driver from feeling uncomfortable. A driving assistance apparatus performs a stop control of stopping a host vehicle so that a following distance between the host vehicle and a stopped vehicle, which is ahead in a course of the host vehicle, approaches a target following distance. The driving assistance apparatus is provided with: a recognizer configured to recognize the stopped vehicle; a speed detector configured to detect a speed ofthe host vehicle; a setting device configured to set the target following distance smaller, if an operation speed is less than a predetermined speed, in comparison with that if the operation speed isgreater than the predetermined speed when one of an acceleration off operation and a brake off operation is performed, or when one of an accelerator opening degree corresponding to an operation amountof an accelerator pedal and a brake opening degree corresponding to an operation amount of a brake pedal is less than or equal to a predetermined opening degree, while the stopped vehicle is recognized.

Description

technical field [0001] The present invention relates to a driving assistance device, in particular to the technical field of a driving assistance device performing assistance related to inter-vehicle distance. Background technique [0002] As such a device, for example, a device has been proposed that separates the detected value of the distance between vehicles and the computed value of the distance between vehicles according to whether the vehicle in front is stopped in order to achieve both control accuracy and comfort when performing inter-vehicle distance control for the preceding vehicle. (Refer to Patent Document 1). In addition, Patent Documents 2 to 4 are also cited as related prior art documents.
