vehicle ride control

Abstract

The present invention relates to a vehicle driving control device that suppresses the shaking of the own vehicle relative to the driving trajectory of the preceding vehicle when following a preceding vehicle. As a control adjustment value for the control amount of the following travel, a first gain (G1) based on the shape data of the preceding vehicle is set in the first control adjustment value setting unit (104), and a second gain (G1) based on the shape data of the preceding vehicle is set in the second control adjustment value. The section (105) sets a second gain (G2) based on the lateral speed of the preceding vehicle. The control amount adjustment unit (103) mainly adjusts the control amount of the following travel based on the first gain (G1) based on the vehicle width ratio of the preceding vehicle and the own vehicle, thereby suppressing the deviation of the driving trajectory of the own vehicle relative to the preceding vehicle. In addition, the second gain (G2) based on the lateral speed of the preceding vehicle is selectively used to adjust the control amount of the following driving according to the situation, thereby avoiding the reduction of the following performance when driving on a curve, etc. .

Description

technical field [0001] The present invention relates to a travel control device for a vehicle that controls follow-up travel that follows a preceding vehicle ahead of a host vehicle. Background technique [0002] Conventionally, there is known a following driving system in which a vehicle such as an automobile travels following a preceding vehicle traveling in front of the own vehicle. The follow-up driving system for the preceding vehicle is, for example, disclosed in Patent Document 1, which captures the preceding vehicle through radar and / or cameras, and automatically controls the steering system, transmission, engine, and brakes. It is effective when driving on roads with lane markings or white lines, or when driving at low speeds such as in traffic jams, the distance between vehicles and the vehicle ahead is reduced, and the front view is limited, making it difficult to recognize the lane (white line).

AI Technical Summary

Problems solved by technology

The follow-up driving system for the preceding vehicle is, for example, disclosed in Patent Document 1, which captures the preceding vehicle through radar and / or cameras, and automatically controls the steering system, transmission, engine, and brakes. Effective when driving on roads with lane markings or white lines, or when driving at low speeds such as in traffic jams, the distance between the vehicle in front and the vehicle ahead becomes narrow, and the front view is limited, making it difficult to recognize the lane (white line).
