Abstract: Provided is a vehicle control device capable of improving robustness against an attitude change of an occupant during preceding vehicle follow-up control in a straddle type vehicle such as a motorcycle. A vehicle control device 100 for a straddle type vehicle that controls a driving force during preceding vehicle follow-up control for causing an own vehicle to follow a preceding vehicle, in which the driving force (which is a control amount of the preceding vehicle follow-up control) is corrected according to an attitude (attitude change) of a driver detected by an attitude detection device 800 during the preceding vehicle follow-up control. Further, the driving force is corrected on the basis of the attitude, the driving torque of the own vehicle, and the acceleration of the own vehicle. In addition, the driving force (according to the attitude) is corrected from at least one of the own vehicle speed of the own vehicle, the target speed, the inter-vehicle distance between the own vehicle and the preceding vehicle, the target inter-vehicle distance, and the relative speed.

Abstract: A control device according to the present disclosure is to provide greater safety than in the conventional system for the occupant while alighting from the vehicle. A control device 10 is mounted on a vehicle 1. The control device 10 includes an attention degree estimation unit 11 and an alighting restriction unit 12. Based on at least one of results detected by an occupant sensor 3 for detecting motion of an occupant of the vehicle 1 and detected by a vehicle sensor 4 for detecting a state of the vehicle 1, the attention degree estimation unit 11 estimates a degree of attention of the occupant to an approaching object approaching the vehicle 1. When the degree of attention of the occupant estimated by the attention degree estimation unit 11 is below the predetermined threshold, the alighting restriction unit 12 causes at least one of the door opening/closing device 6, the audio output device 7, and the image display device 8 in the vehicle 1 to execute the alighting restriction operation.

Abstract: Provided is a sensor recognition integration device capable of reducing the load of integration processing so as to satisfy the minimum necessary accuracy required for vehicle travel control, and capable of improving processing performance of an ECU and suppressing an increase in cost. A sensor recognition integration device B006 that integrates a plurality of pieces of object information related to an object around an own vehicle detected by a plurality of external recognition sensors includes: a prediction update unit 100 that generates predicted object information obtained by predicting an action of the object; an association unit 101 that calculates a relationship between the predicted object information and the plurality of pieces of object information; an integration processing mode determination unit 102 that switches an integration processing mode for determining a method of integrating the plurality of pieces of object information on the basis of a positional relationship between a specific region (for example, a boundary portion) in an overlapping region of detection regions of the plurality of external recognition sensors and the predicted object information; and an integration target information generation unit 104 that integrates the plurality of pieces of object information associated with the predicted object information on the basis of the integration processing mode.

Abstract: Provided is a sensor information processing device that processes the detection results of the plurality of external-environment sensors that recognize the lane marker that divides the lane and can identify the lane marker more accurately than before. A sensor information processing device 100 includes a storage device 102 that stores a past detection result De of an external-environment sensor 200 as time-series data, and a central processing unit 101 that identifies a lane marker on the basis of the time-series data. The central processing unit 101 determines that the new detection result De belongs to the existing lane marker or the new lane marker on the basis of the comparison between the new detection result De not included in the time-series data and the time-series data.
