no. 1 approach

[0037] figure 1 It is a functional block diagram showing an example of the configuration of the travel control system 1 according to the first embodiment of the present invention.

[0038] Such as figure 1 As shown, the travel control system 1 of this embodiment is a system mounted on the vehicle 2 to automatically control part or all of the travel of the vehicle 2, and includes a vehicle-mounted control device 10, a vehicle-mounted display device 20, a wireless communication unit 30, a Vehicle position measuring device 40, external environment sensor group 50, vehicle sensor group 60, actuator group 70, etc.

[0039] The in-vehicle control device 10 is, for example, an ECU (Electronic Control Unit, electronic control unit) mounted on the vehicle 2 , and has a processing unit, a storage unit 120 , and a communication unit 130 . In addition, the form of the vehicle-mounted control device 10 is not particularly limited. For example, it may be a driving control device for reali...

no. 2 approach

[0171] In the first embodiment, in order to determine the level of discomfort felt by changes in driving behavior and driving control, the in-vehicle control device 10 stores a combination pattern of control events indicating the possibility of causing discomfort and their causes. Discomfort Patterns Dataset124. In the second embodiment, an example in which a sense of discomfort in control is determined in a different manner will be described.

[0172] exist Figure 17 1200 shows the uncomfortable feeling judgment processing flow. This is equivalent to the second embodiment Figure 8 The discomfort judgment process of step 652.

[0173] After acquiring the control event information (step 1201), the in-vehicle control device 10 checks whether the control event is caused by a change in driving behavior (step 1202). If it is due to a change in driving behavior, the discomfort level is set to 3 (maximum value) (step 1206), and the process ends. This means that a control event...

no. 3 approach

[0181] In the first embodiment and the second embodiment, an example of a method of notifying the contents and causes of the changes triggered by the driving action and the traveling state has been described. On the other hand, there are cases where the user feels uncomfortable without a change in the driving behavior and driving control. In the present embodiment, an example of means for notifying the user of a situation that may cause discomfort to the user is detected regardless of whether the driving behavior or travel control has changed will be described.

[0182] In this embodiment, in the travel control content determination process, when calculating the target steering angle and the target vehicle speed (corresponding to Figure 7 Step 602 and Step 603) of the calculation result to confirm whether the user will feel uncomfortable.

[0183] The target vehicle speed calculation process will be described as an example. As described in the first embodiment, with respect...

Abstract

The present invention provides a travel control system (1). The travel control system (1) having: an onboard control device (10) installed in a vehicle (2), the onboard control device (10) controlling the traveling of the vehicle (2); and an onboard display device (20) communicably connected with the onboard control device (10), the onboard display device (20) using a screen display and / or audio output to present information to an occupant of the vehicle (2), wherein: the onboard control device (10) acquires external surroundings recognition information recognized by an external surroundings sensor (50) and / or out-of-vehicle communication, determines driving action specifics that should be taken by the vehicle (2) on the basis of the external surroundings recognition information, specifies a driving action factor that is the reason for determining the driving action specifics, and outputs the driving action specifics and the specified driving action factor; and the onboard display device (20) acquires the driving action specifics and the driving action factor outputted by the onboard control device (10) and gives notification of the driving action specifics and the driving action factor by using a screen display and / or audio output, thereby reducing any instability and / or sense of discomfort experienced by the driver and / or occupants due to the automatic travel control of the vehicle (2).

Description

technical field [0001] The present invention relates to a travel control device, a vehicle-mounted display device, and a travel control system. Background technique [0002] This application claims the priority of Japanese Patent Application No. 2014-79953 for which it applied on April 9, 2014, The content is taken in here as a reference. [0003] There is known a system for automatically controlling the running of a vehicle by using an on-vehicle external environment sensor such as a radar or a camera to recognize conditions around the vehicle. In such a system, when performing control, there is a problem that the driver and passengers cannot grasp the purpose of the control instantaneously and feel uncomfortable. In addition, in automatic driving control in which the system has the initiative to drive, there is a problem that it is difficult to grasp the will of the vehicle to implement a series of driving controls, and the driver and passengers may feel uneasy. [0004]...
