A passenger seat occupancy alert system for a vehicle is disclosed herein. The passenger seat occupancy alert system for a vehicle includes at least one sensor, a detection means, an in-vehicle display device, a speaker, and a controller. The passenger seat occupancy alert system is useful for sensing passenger occupancy of a vehicle and producing an alert.

In a method and a corresponding system for identifying a fuel loss event, periodic measurements of a measured volume of fuel stored in a fuel tank (mobile or stationary) are received, and a measurement of a dispensed volume of fuel dispensed into the fuel tank is received from a fueling station. A total volume of fuel is determined equal to the sum of the dispensed volume of fuel and the measured volume of fuel last measured prior to receiving from a fueling station. A difference is determined between the total volume and the measured volume of fuel first measured subsequent to determining the total volume. If the difference exceeds a predetermined threshold indicating a fuel loss event, an alert is generated indicating that there is a fuel loss event.

Provided are an apparatus and method for monitoring driver's concentrativeness capable of monitoring whether a driver is concentratedly obtaining major information by tracing a driver's sight while a vehicle is running, in order to provide alarm to the driver when driver's concentrativeness is dropped at a time when the major information is changed while the vehicle is running.

An apparatus for determining a concentration of a driver includes: a region-of-interest definition processor configured to define a region-of-interest based on traffic-related information on front image information of a vehicle running; a driver eye-gaze detection processor configured to detect a plurality of eye-gaze points from driver image information of a driver in accordance with an eye-gaze movement of the driver; a driver concentration information calculation processor configured to calculate concentration information of each of the eye-gaze points; an image coordinate system processor configured to convert the region-of-interest to an image coordinate system and convert positions of the eye-gaze points to the image coordinate system; and a concentration determination processor configured to determine a concentration of the driver on the image coordinate system based on the concentration information.

In a method for operating a fuel tank system for a motor vehicle, with the fuel tank system having a fuel tank and an accumulation tank to which a suction side of a fuel pump is connected, at least one sensor determines a geodetic orientation of the fuel tank when a fill level of the fuel tank is below a predetermined minimum fill level. A fueling parameter is read out from a characteristic curve field based on the geodetic orientation, and the fueling parameter is displayed by a signaling device.

A vehicular shift operation apparatus that includes a manual transmission including an input-side sub-transmission and an output-side sub-transmission, and that is capable of preventing overrun or underrun due to erroneous shift operation, is provided. The vehicular shift operation apparatus includes a manual transmission including an input-side sub-transmission and an output-side sub-transmission, and includes: a main shaft rotation speed sensor that detects a main shaft rotation speed, a sensor that detects a position of a clutch pedal, and a controller. The controller has a function of detecting a gear stage at a control cycle (current gear stage) and a function of determining whether the detected gear stage is correct or not.

A speed controlling method for a vehicle comprises obtaining a driving speed limit of a road ahead from a navigation system of the vehicle. A current driving speed of the vehicle is detected and if the current driving speed of the vehicle is greater than the limit ahead, a driver of the vehicle is informed that he must slow down in a distance between the vehicle and a speed measuring device located on the road ahead.

A method for providing a warning to a vehicle driver when a lane keeping and/or lane centering system will be unable to negotiate a tight curve at the present vehicle speed prior to the vehicle reaching the curve. The method obtains lane information at a predetermined number of sample times in the future and generates a desired path for the vehicle. The method also obtains vehicle motion information and determines steering angles for the vehicle for the vehicle to track the desired path based on the desired path and vehicle motion. The method determines the steering torque for each of the steering angles and determines whether any of the steering torques exceed the predetermine torque limit. The method issues an alert if any of the steering torques do exceed the predetermined torque limit prior to the lane keeping system being required to provide that torque to steer the vehicle.

An in-vehicle camera control device 1 includes an evaluator 11 for evaluating an image capturing condition with reference to an image captured by an in-vehicle camera 2, an image capture suitability determiner 12 for determining whether to continue image-capturing in accordance with evaluation results generated by the evaluator 11, and a drive controller 14 for outputting a drive signal to a drive unit 22 of the in-vehicle camera 2 causing the drive unit 22 to move the in-vehicle camera 2 when the image capture suitability determiner 12 determines that the in-vehicle camera 2 is unsuitable for the image-capturing. Thus, it is possible to move the in-vehicle camera 2 to a position where a normal image can be captured when wipers etc. fail to improve the image capturing conditions.

A system for managing refueling and charging of a plug-in hybrid vehicle is provided to prevent charging from being performed simultaneously with refueling to prevent accidents attributable to the occurrence of gas fumes and static electricity. The system includes a plurality of input units configured to receive instructions for refueling and charging a battery. A fueling/charging controller is configured to determine whether a process for refueling and a process for charging the battery are progressing and to start a process that corresponds to the instruction input from any one of the plurality of input units when neither the process for refueling nor the process for charging the battery is progressing.
