A driver is informed, according to a state of a vehicle, about each problem. When there is a breakdown of the brake light system, such as a brake lights fuse disconnection, a breakdown of a brake lights relay, a wiring disconnection or defective wiring contact or the like, the driver is informed of the breakdown. Then rear vehicle is informed of danger by flickering a turn signal light since the brake lights do not light when the brake light system and the brake lights have broken down. The driver is informed of the breakdown of the brake light system and the brake lights by operating an internal alarm means whenever the driver steps on and releases the brake, thereby enabling the driver to drive safely.

    Abstract: In a face image capturing device, a focal point of a fixed-focus in-vehicle camera is set to a position where a circle of confusion with respect to a foremost face position is larger than the circle of confusion with respect to a rearmost face position. The rearmost face position is where the driver's face is positioned when a driver's seat is moved to the rearmost limit. The foremost face position is where the driver's face is positioned when the driver's seat is moved to the foremost limit. When the focal point of the in-vehicle camera is set to the above position, the focal point can be moved rearward to reduce the blurring of a face image at the rearmost face position. Even if the blurring of the face image at the rearmost face position is increased, a driver condition can be accurately determined at all times.

    Abstract: When a detection signal indicates that a switch has switched off, a first relay cuts off the supply of alternating current from a commercial alternating-current source to a third DC power source and terminates a first load such as a motor and a high-voltage power source. When the detection signal indicates that the switch has switched off, a control circuit executes shutdown processing for safely terminating an operation of a second load such as a hard disk drive. When the shutdown processing is complete, the control circuit outputs a signal for terminating an operation of a second DC power source. When the shutdown signal is input, a second relay terminates the operation of the second load by cutting off the supply of the alternating current from the commercial alternating-current source to a second DC power source.

  • Patent number: 8125326
    Abstract: A method, system and computer program product for providing notification to the driver of a vehicle when the vehicle's speed exceeds the speed limit within a speed control zone. A vehicular speed control (VSC) utility retrieves information indicating the speed limit of the speed control zone from an information signal detected by a radio receiver. The receiver is electrically coupled to the speed sensor circuitry of the vehicle to track the vehicle's velocity. The VSC utility determines whether to activate a speed notification alarm by comparing the vehicle's velocity with the zone's speed limit. When the vehicle's velocity exceeds the speed limit of the speed control zone, the VSC utility triggers the alarm and alerts the driver of the excessive speed with an audible/visible notification. The VSC utility may re-trigger the alarm if the driver continues to exceed the speed limit while driving within close proximity of the speed control zone.

  • Patent number: 8054171
    Abstract: A method and apparatus for allowing a troubleshooter to reuse existing indicators, such as displays, LEDs, or specialized indicators, for a purpose other than the indicator's usual purpose. In response to an initial occurrence of a problem, the troubleshooter modifies the indicator's behavior to indicate a later occurrence of a fault or a set of faults, which may be the cause of the problem. Upon the later occurrence of the problem, the indicator is monitored for simultaneous notification of occurrence of the fault. After the problem is triaged, the modified indicator is returned to its original use. The notification from the indicator can be sensory, i.e., auditory, visible, or tactile. The indicator's change in behavior can occur after the fault happens once or an administrable threshold number of times, or intermittently. Alternatively, the change in behavior may become semi-permanent if the fault continues to occur for some administrable number of times.

  • Patent number: 7948391
    Abstract: A signaling device for a safety circuit has an input part for receiving an external state variable, at least one switching element and a control part. The control part controls the at least one switching element as a function of the external state variable, such that a signal applied to the input is communicated to the output. According to one aspect of the invention, the input of the switching element is internally connected to a fixed potential, preferably a fixed High potential. In a safety circuit for turning off a hazardous installation, such signaling devices are connected in series with one another to a safety controller. In such an arrangement, the control part of the downstream second signaling device also controls its switching elements as a function of the output of the first signaling device.

  • Patent number: 7865279
    Abstract: A control center transmits failure information transmission request information to a vehicle. The vehicle receives the failure information transmission request information transmitted from the control center. A navigation ECU and a gateway ECU obtain failure information from each ECU in cooperation with each other. At this time, the gateway ECU determines whether a data volume of the failure information is larger than a predetermined information volume. When it is determined that the data volume of the failure information is larger than the predetermined information volume, the gateway ECU divides the failure information into plural pieces, and outputs each piece of information. Also, the ECU does not output the failure information, which is output to a network built in the vehicle, to the navigation ECU, while a failure information obtaining device is connected. Meanwhile, the control center does not receive the failure information while the failure information obtaining device is connected.

For example, the visible light is irradiated on a target switch based on signals indicating an on/off state of a headlamp operation switch and an on/off state of a key switch. A user 5 can easily confirm the target switch and unerringly operate the target switch. A visible light irradiator 6 is arranged in a vehicle compartment and irradiates the visible light to display information in the vehicle compartment. The information can be provided for the user 5 in a novel manner.

  • Patent number: 7777495
    Abstract: Provided are a device and a method of detecting signal lamps in a vehicle, in particular in a large vehicle, being provided with a plurality of signal lamps each being capable of switching between an OFF-phase and an ON-phase. The method includes the steps of during the OFF-phase of a vehicle signal lamp to be probed inducing a probing current by connecting an electric current generator to said vehicle signal lamp circuit, where the probing current is lower than the nominal current for the lamp in question. The next step is to detect the electric voltage level over the lamp circuit and determining vehicle signal lamp characteristics such as type and condition based on said electric voltage level detection. The result of the determination is that the signal lamp is a LED lamp being connected, when the detected voltage level is within a predetermined interval between a first voltage level and a second voltage level.
