  • Patent number: 9079526
    Abstract: A driving ability reduction determining apparatus comprising a virtual image display portion, an operation portion, a response detection portion and a driving ability determination portion is disclosed. The virtual image display portion emits a determination-usage display image toward a windshield, thereby displaying to the driver the determination-usage display image as a virtual image through the windshield. The operation portion is operated by the driver when the driver visually recognizes the determination-usage display image. The response detection portion detects a response situation of driver's operation of the operation portion in response to display of the determination-usage display image by the virtual image display portion. The driving ability determination portion determines the driving ability reduction of the driver based on a detection result of the response detection portion.

  • Publication number: 20150150488
    Abstract: In an evaluation process, a first muscle strength (i.e., muscle potential) of a first muscle responsible for a dorsiflexing action of the ankle joint of a leg manipulating an accelerator pedal is acquired using a first muscle potential sensor. A second muscle strength (i.e., muscle potential) of a second muscle responsible for a plantarflexing action of the ankle joint of the leg manipulating the accelerator pedal is acquired using a second muscle potential sensor. Then, on the basis of time-series variation of each of the muscle potentials acquired using the first and second muscle potential sensors, a synchronous activity level is calculated as an evaluation index. When the difference between the evaluation index and an evaluation standard pre-determined is not less than a prescribed value, it is evaluated that an occupant of a vehicle feels stress as a result of manipulating an in-vehicle information apparatus while driving the vehicle.

  • Publication number: 20140353457
    Abstract: A casing for housing an occupant protection device unit is composed of a metallic base with its plate surfaces facing upward and downward, respectively, and a main body that is put on and mounted on the surface of the base. A bracket formed integrally with the base is composed of a plate-like leg extending laterally from the edge in the base and a fastening member that is integrally formed at an end of the leg and is bolted to the vehicle body. The leg is composed of a through-hole vertically passing therethrough and the two weak portions. The two weak portions are composed of two branching portions separated by the through-hole in the leg. If an excessive collision load is exerted on the bracket from the vehicle body, the two weak portions are torn off, thereby allowing the occupant protection control unit to be protected.

  • Patent number: 8471909
    Abstract: In a hand-free driving warning process for a vehicle, when a grip state of a steering wheel is in a hand-free driving state, and the vehicle is in a travel state stipulated previously, a danger degree is derived based on a position of a vehicle compartment where a non-grip hand exists. In deriving the danger degree, when the non-grip hand is in a high danger position, a high level is set; when the non-grip hand exists in a low danger position, a middle level or a low lever is set. In the low level, any warning is not outputted; in the middle level, a warning is outputted in a sound volume smaller than a usual sound volume; and in the high level, a warning is outputted in the usual sound volume or greater.

  • Patent number: 8284252
    Abstract: A detection unit obtains a position of a feature point of an occupant. A storage unit stores a model of all specific actions in each of physical feature classifications. The model defines a position or a locus of the feature point in each specific action, which an occupant may perform. A determining unit compares an in-action feature point with each model of a specific action, which is being performed, to determine a classification conformity weight indicating a possibility that the occupant belongs to the physical feature classification. An estimating unit compares the position of the feature point with each model to obtain a comparison result and generate a conformity value by incorporating the classification conformity weight into the comparison result. The estimating unit detects an estimated action, which is a specific action corresponding to the model, which has a highest conformity value.

  • Patent number: 8260000
    Abstract: A storage unit stores a model defining a position or a locus of a feature point of an occupant in each specific action. An action estimation unit compares the feature point with each of the models to detect an estimated action. A detecting unit detects that a specific action is being performed as a definite action. A first generating unit generates a new definite model corresponding to the definite action by modifying a position or a locus of the feature point according to an in-action feature point when the definite action is being performed. A second generating unit generates a new non-definite model using the in-action feature point according to a correspondence between the feature point in the definite action and the feature point of a non-definite model other than the definite model. An update unit updates the definite action model and the non-definite action model.
