Problems solved by technology

[0006] However, in the case where the driving force is restored after the adherent matter of the obstacle detection device has been erroneously detected as an obstacle, if restrictions are imposed as described in JP2011-122607A or JP2012-061932A, although the The obstacle is not present, but the desired acceleration is not achieved, so the driver may experience a strange or uncomfortable sensation

no. 1 approach

[0022] figure 1 is a block diagram showing an example of a system configuration including the driving assistance device 1 according to the present embodiment.

[0023] as in figure 1 As shown in , the driving assistance device 1 includes a driving assistance ECU 10 .

[0024] The driving assistance ECU 10 is formed of a microcomputer, and includes, for example, a ROM, a readable / rewritable RAM, a timer, a counter, an input interface, an output interface, and the like. The ROM stores control programs. The RAM stores calculation results and the like. The functions of the driving assistance ECU 10 may be realized by any one of hardware, software, and firmware, or a combination of any two or more of them. For example, selected parts or all of the functions of the driving assistance ECU 10 may be realized by an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA). Part or all of the functions of the driving assistance ECU 10 may be realized ...

no. 2 approach

[0086] Next, a second embodiment will be described.

[0087] The main difference of this embodiment from the first embodiment is that the distance to the obstacle detected just now is used as an index of the possibility of the presence of an obstacle around the host vehicle. Hereinafter, the same reference numerals denote constituent elements similar to those of the first embodiment, and differences will be mainly described.

[0088] The system configuration of the driving assistance device 1 according to the present embodiment is as in the case of the first embodiment in figure 1 , so its description is omitted.

[0089] Next, a flow chart of driving assistance performed by the driving assistance device 1 according to the present embodiment, particularly a flow chart of driving assistance performed for collision avoidance, including intervention to suppress driving force and then recovering the suppressed driving force, will be described. .

no. 3 approach

[0098] Next, a third embodiment will be described.

[0099] The main difference between this embodiment and the first embodiment is whether the recovery mode is selected by the driver and the recovery mode selected by the driver is used as an index of the possibility of an obstacle existing around the host vehicle. Hereinafter, the same reference numerals denote constituent elements similar to those of the first embodiment, and differences will be mainly described.

[0100] The system configuration of the driving assistance device 1 according to the present embodiment is as in the case of the first embodiment in figure 1 , so its description is omitted.

[0101] Next, a flow chart of driving assistance performed by the driving assistance device 1 according to the present embodiment, particularly a flow chart of driving assistance performed for collision avoidance, including intervention to suppress driving force and then recovering the suppressed driving force, will be descri...

Abstract

A driving assistance apparatus includes: an obstacle detecting unit configured to detect an obstacle outside a host vehicle and acquire obstacle information including a distance to the obstacle; a collision avoidance control unit configured to execute driving force suppression control for intervening to suppress driving force on the basis of the obstacle information acquired by the obstacle detecting unit; and a driving force return control unit configured to execute driving force return control for returning the driving force suppressed by the driving force suppression control, have a plurality of return modes in which the driving force is returned by the driving force return control, and return the driving force in one return mode selected from among the plurality of return modes on the basis of a possibility that there is an obstacle around the host vehicle.

Description

technical field [0001] The present invention relates to driving assistance technology. Background technique [0002] Known is a driving assistance device that detects an obstacle around a host vehicle by an obstacle detection device or the like (for example, an ultrasonic sensor or a millimeter-wave radar) and avoids a collision with the obstacle. This driving assistance device avoids a collision with an obstacle mainly by performing an intervention control for suppressing the driving force of the host vehicle or generating a braking force (see Japanese Patent Application Publication No. 2011-122607 (JP 2011-122607A) and Japanese Patent Application Publication No. .2012-061932 (JP2012-061932A)). [0003] After avoiding a collision with an obstacle by the driving assistance device, for example, if the driving force suppressed by the intervention control is restored, because there is a high possibility that the obstacle is still around the host vehicle, there is a negative im...
