A system and method are provided and include a light source projector with a positional actuator mounted on a subject vehicle that projects a laser line on a roadway upon which the subject vehicle is traveling. A controller is in communication with a platoon vehicle traveling in front of or behind the subject vehicle in a platoon and controls the positional actuator to project the laser line on the roadway between the subject vehicle and the at least one platoon vehicle.

A travel assistance device includes an actuator and an electronic control unit. The electronic control unit is configured to predict a future position of a vehicle and an object, set an assistance range around the vehicle, determine whether an avoidance start condition is satisfied and in which of a first roadway area, a second roadway area, and a sidewalk area the object is positioned, set the avoidance start condition and a movement range of the object, so that the avoidance start condition is more easily determined to be satisfied when the object is in the first roadway area than when the object is in the second roadway area, and more easily determined to be satisfied when the object is in the second roadway area than when the object is in the sidewalk area, and perform a collision avoidance operation when the avoidance start condition is satisfied.

Methods of assessing driver behavior include monitoring vehicle systems and driver monitoring systems to accommodate for a slow reaction time, attention lapse and/or alertness of a driver. When it is determined that a driver is drowsy, for example, the response system may modify the operation of one or more vehicle systems. The response system can modify the control of two or more systems simultaneously in response to driver behavior.

A lane departure prevention device includes: a travelling state recognition unit; a lane line recognition unit; a departure determination unit; a yaw moment calculation unit configured to calculate a target trajectory and a target yaw moment; a direction determination unit configured to determine the departure avoidance direction; a direction alignment determination unit configured to determine the turning direction of the vehicle by the target yaw moment coincides with the departure avoidance direction; and a braking force control unit configured to control the braking forces of the vehicle. In a case where the direction alignment determination unit determines that the results of determinations coincide with each other, the braking force control unit perform a braking force control, and in a case where the direction alignment determination unit doesn't determine that the results of determinations coincide with each other, the braking force control unit doesn't perform the braking force control.

Methods of assessing driver behavior include monitoring vehicle systems and driver monitoring systems to accommodate for a driver's slow reaction time, attention lapse and/or alertness. When it is determined that a driver is drowsy, for example, the response system may modify the operation of one or more vehicle systems. The systems that may be modified include: visual devices, audio devices, tactile devices, antilock brake systems, automatic brake prefill systems, brake assist systems, auto cruise control systems, electronic stability control systems, collision warning systems, lane keep assist systems, blind spot indicator systems, electronic pretensioning systems and climate control systems.

A vehicular control system includes a plurality of cameras that capture image data, at least one radar sensor that senses radar data and a control that processes image data captured by the cameras and sensed radar data. The control, responsive to processing of captured image data, detects lane markers and/or road edges and determines curvature of the road being traveled by the equipped vehicle. The control processes captured image data and sensed radar data to detect vehicles. The control, based on processing of captured image data and/or sensed radar data, detects another vehicle and determines distance from the equipped vehicle to the detected other vehicle. The control may, based at least in part on the detection of another vehicle and the determination of distance from the equipped vehicle to the detected other vehicle, determine whether it is safe for the equipped vehicle to execute a lane change maneuver.

Described herein is a vehicle system configured to identify and mitigate inappropriate driving behavior. In some embodiments, the vehicle system may receive input information from one or more input sensors. The vehicle system may identify driving behaviors related to a vehicle from the received input. The vehicle system may determine whether the driving behaviors are inappropriate in light of one or more conditions affecting the vehicle. Upon identifying inappropriate behavior, the vehicle system may generate a set of corrective actions capable of being executed to mitigate the inappropriate driving behavior.

A boundary line recognition apparatus receives detection results transmitted from camera devices and a laser radar device performing different optical detection methods. These detection results indicate information regarding a lane boundary line of a vehicle lane on a roadway on which an own vehicle drives. The apparatus further obtains surrounding environmental information of the own vehicle on the roadway, and selects at least one of the camera devices and the laser radar device suitable for correctly recognizing the lane boundary line on the basis of the environmental information. The apparatus finally recognizes the lane boundary line with high accuracy on the basis of the detection result transmitted form one or more devices selected based on the environment information.

a brake control system adapted to prevent or reduce noise is provided.

A brake control system switches a pressure increase mode between first pressure increase that closes a differential pressure valve placed between a master cylinder and a wheel cylinder and activates a pump to increase wheel cylinder hydraulic pressure and second pressure increase that allows brake fluid to leak through the differential pressure valve and activates the pump to increase the wheel cylinder hydraulic pressure, according to the state of a vehicle.
