Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described with reference to the drawings. exist figure 1 In the figure, reference numeral 1 is a driving assistance system of a vehicle, which executes driving assistance control including automatic driving based on the recognition result of the external environment of the host vehicle for the driver's driving operation. This driving assistance system 1 is configured such that an external environment monitoring device 20 , an engine control device 30 , a brake control device 40 , a steering control device 50 , an alarm control device 60 , and the like are connected to an in-vehicle network 100 centering on a travel control device 10 .

[0042] The external environment monitoring device 20 is configured by combining a device group that can autonomously recognize the external environment and a device group that acquires information through communication with the outside. The former device group includes a camera ...

Abstract

A driving support system optimizes cooperative control of steering and deceleration control, ensures following precision of a travel route of a trate and inhibits disorder of an elastic system in the vehicle. A deceleration control part 14 includes: a target steering angle calculation unit 12 that calculates a target steering angle at the time of passing through a curved section of the target travel route; a target deceleration calculation unit 13 that calculates a target deceleration in the curved section; a deceleration correction value calculation unit that calculates, on the basis of the target steering angle and an actual steering angle, a corrected vehicle speed for correcting a target vehicle speed determined by the target deceleration; and a deceleration correction unit 15 that corrects the target deceleration such that the target vehicle speed becomes the corrected vehicle speed. The system reduces the feedback correction value on the basis of steering angle control of deflection of target steering angle and actual steering angle without inversion of steering, thereby ensuring following precision of a travel route of a trate and inhibiting disorder of an elastic system in the vehicle.

Description

technical field [0001] The present invention relates to a driving assistance system for a vehicle that causes an own vehicle to follow a target travel route through steering control and deceleration control. Background technique [0002] Generally, in vehicles such as automobiles, steering control and brake control are provided as independent functions. There is a problem that the operational burden imposed on the driver becomes large. [0003] In contrast, Patent Document 1 discloses a technique of selecting either one of steering control and braking control to be mainly performed, and outputting a main side demand value as a demand value of a vehicle turning motion performed on the main side based on the selection result. , and output the non-primary side request value as the request value based on the difference between the target value and the primary side request value to the non-primary side, thereby performing coordinated control of steering control and braking contr...
