  • Patent number: 10286913
    Abstract: A computer-implemented method for controlling a vehicle system of a host vehicle merging with one or more remote vehicles, including receiving speed data transmitted from the one or more remote vehicles via a vehicular communication network and receiving position data of the one or more remote vehicles from the sensor system of the host vehicle that monitors an area around the host vehicle. Upon determining the one or more remote vehicles are in the area around the host vehicle based on the position data, determining a safe distance for merging into the lane based on a relative position of the host vehicle to the one or more remote vehicles. Further, controlling the vehicle system of the host vehicle according to an actual distance between the host vehicle and the one or more remote vehicles and the safe distance.

  • Publication number: 20180345961
    Abstract: A vehicle control system for use with a host vehicle configured for travel along a path is described. The vehicle control system includes a processor configured to access a host location and host speed of the host vehicle. The processor is also configured to detect a follower location and follower speed of a following vehicle behind the host vehicle on the path. A tailgating distance is calculated between the host vehicle and the following vehicle. The following vehicle is identified as a tailgating vehicle when the tailgating distance is less than or equal to a first warning distance or when the follower speed is greater than the host vehicle within a second warning distance. A tailgating protocol of the host vehicle is initiated for the tailgating vehicle based on a differential speed between the host speed and the follower speed.

  • Patent number: 9658243
    Abstract: In a first arousal level estimation device according to this invention, an initial residual setup unit sets a residual to be a reference of a driver, i.e., a residual with a smallest value during an initialization period as an initial residual among residuals calculated by a residual calculation unit during the initialization period from timing of starting an operation of a vehicle or timing of a change in a traveling scene including a condition of traveling road of the vehicle as a starting point till a predetermined period of time elapses. An arousal level estimation unit estimates a driver's arousal level based on a result of comparison between the initial residual set by the residual setup unit and the residual calculated by the residual calculation unit after the initialization period has elapsed. In this way, an estimation accuracy relating to a driver's state including a driver's arousal level is improved.

  • Patent number: 9061630
    Abstract: A vehicle travel control device can accurately determine a driver's intention to adjust the vehicle speed. After applying attention attracting reaction force corresponding to outside circumstances and the like to an accelerator pedal through a reaction force application mechanism, a reaction force control unit outputs intention determining reaction force that is used to determine the driver's intention to adjust the vehicle speed and is smaller than the attention attracting reaction force, and determines the intention to adjust the vehicle speed on the basis of the accelerator pedal operation amount of the driver while the intention determining reaction force is being applied to the accelerator pedal through the reaction force application mechanism.

  • Patent number: 8706374
    Abstract: An accelerator pedal device provided with a driving control device. The driving control device generates a braking force for braking a vehicle when the operation quantity of an acceleration pedal is below a first threshold value, and generates a driving force for driving the vehicle when the operation quantity exceeds a second threshold value larger than the first threshold value. The driving control device does not generate either the driving force or the braking force, and allows the vehicle to drive inertially, when the operation quantity ranges from the first threshold value to the second threshold value.

  • Patent number: 8489253
    Abstract: A driver state assessment device is provided in which when driver model identification means (M2) identifies a driver model showing a driver's input/output relationship using a difference between a target azimuth and an actual azimuth as a driver's input and an actual steering angle as a driver's output, driver model amount of operation acquisition means (M3) acquires a driver model steering angle by inputting a current azimuth deviation into the driver model, and driver state assessment means (M4) calculates a difference between a current actual steering angle and a driver model steering angle as a residual error and assesses the driver's state based on the residual error. Therefore, since the residual error is an index that represents a fluctuation component, a noise component, a non-linear component, etc. obtained from the driver model, it is possible to assess, with high precision, the driver's state, in particular a low wakefulness state of the driver, based on this residual error.
