Problems solved by technology

[0004] However, in this driving assistance system, since only the driving state of the vehicle in front and the previous vehicle is followed, the driving state of the other vehicle is not considered.
That is, in this driving assistance system, it is not possible to perform follow-up driving control of the host vehicle in consideration of the running states of a plurality of surrounding vehicles existing around the host vehicle.

no. 1 Embodiment approach

[0047] A first embodiment of the follow-up travel control device of the present invention will be described. figure 1 The follow-up driving control device 1 of the present embodiment shown is mounted on figure 2 Shown vehicle M 0 on, for use in accordance with the M 0 The vehicle M is realized in a manner corresponding to the driving state of the surrounding vehicles traveling around 0 The following driving system. This follow-up travel control device 1 can realize follow-up travel under the situation that there are many surrounding vehicles of any number, here, as figure 2 shown in the present vehicle M0 Let’s take a case where there are three surrounding vehicles driving in front of you as an example.

[0048] In the following instructions, use "M 1 ” means from the vehicle M 0 Look at the first surrounding vehicle ahead, use "M 2 "Indicates the second surrounding vehicle, use "M 3 ” indicates the third surrounding vehicle. In addition, figure 2 in the surroundin...

no. 2 Embodiment approach

[0087] Next, a second embodiment of the follow-up travel control device of the present invention will be described. Mounted on this vehicle M 0 The physical configuration of the follow-up travel control device 201 of this embodiment is as follows: figure 1 As shown, since it is the same as the follow-up travel control device 1 , redundant description is omitted.

[0088] Such as Figure 4 As shown, here, the surrounding vehicle M 1 By autonomous ACC (Adaptive Cruise Control: Adaptive Cruise Control), the vehicle immediately ahead, that is, the surrounding vehicle M 2 Set it to follow the target, and control the distance L between the vehicles ahead 2 . In this case, the surrounding vehicle M 1 target acceleration u 1 use

[0089] u 1 =k 4 D. 2 +C 4 D. 2 ’ …(2.1)

[0090] express. Such as Figure 4 As shown, this is based on the surrounding vehicles M 1 with a spring constant of k 4 The spring K 4 and an attenuation factor of c 4 shock absorber C 4 Spring s...

no. 3 Embodiment approach

[0110] Next, a third embodiment of the follow-up travel control device of the present invention will be described. Mounted on this vehicle M 0 The physical configuration of the follow-up travel control device 301 of this embodiment is as follows: figure 1 As shown, it is the same as the follow-up travel control device 1, so repeated descriptions are omitted.

[0111] In addition to the above-mentioned control method of the following travel control device 1, the following travel control device 301 also controls the own vehicle M 0 The driving state of surrounding vehicles behind is taken into account.

[0112] Such as Figure 6 As shown here, in the ego vehicle M 0 The following surrounding vehicles M 1r is the communication vehicle, and set the target inter-vehicle distance L tgt_1r, while using the front vehicle distance sensor to measure the front vehicle distance L 1r Front-vehicle distance L under side control 1r . In addition, for surrounding vehicles M 1r Calcu...

Abstract

Provided is a follow-up run control device for controlling the running state of a driver's vehicle while a nearby vehicle is running ahead or behind thereof. The follow-up run control device comprises a deviation acquiring means for acquiring, in connection with the driver's vehicle and the nearby vehicle, the information on the deviations between relative position relations to an immediately preceding vehicle and target relative position relations, and a follow-up control quantity calculating means for calculating the follow-up control quantities of the driver's vehicle on the basis of the information on the deviations of the plural vehicles, as acquired by the deviation acquiring means, thereby controlling the running state of the driver's vehicle.

Description

technical field [0001] The present invention relates to a follow-up driving control device for controlling the running state of a host vehicle in the presence of surrounding vehicles traveling in front of or behind the host vehicle. Background technique [0002] In recent years, in order to reduce the burden on the driver during vehicle driving, a technique of controlling the running state of the own vehicle according to the running state of the preceding vehicle or the like has attracted attention. Conventionally, a driving assistance system described in the following Patent Document 1 is known as such a follow-up driving control technique. In this system, not only the vehicle in front of the own vehicle, but also the previous vehicle in front is treated as a hypothetical preceding vehicle, and the one with the larger target deceleration relative to the preceding vehicle and the preceding vehicle is selected, or the one with the smaller target acceleration is selected as F...
