In one embodiment of the vehicular display system, the drawing unit operates when the vehicle speed is within a predetermined low speed area, starts an operation thereof when the vehicle speed becomes above a lower limit of the low speed area, and stops the operation thereof when the vehicle speed exceeds an upper limit of the low speed area.

An autonomous driving control system and a method thereof are provided. The autonomous driving control system includes a strategy performing device that generates and performs a stop strategy of a vehicle on the basis of a target stop location, when a critical situation occurs during autonomous driving, a behavior controller that controls a behavior of the vehicle depending on the stop strategy, and an emergency module controller that runs a predetermined emergency module, when the critical situation occurs.

Systems, methods, and other embodiments described herein relate to improving alert activation for rear collision avoidance. In one embodiment, a method includes responsive to detecting a target object that is located behind a subject vehicle, determining, by the subject vehicle, characteristics about a surrounding environment of the subject vehicle, including of the target object. The method includes analyzing the characteristics to identify lateral free space next to the subject vehicle that is an area without obstruction beside the subject vehicle. The method includes modifying a collision threshold for activating an alert to the target object according to the lateral free space.

A computer is programmed to deploy an aerial drone to fly within a specified distance of a first vehicle. The computer is programmed to detect a second vehicle and then activate an aerial drone light.

A rear-road surface illumination apparatus is provided which includes: an avoidance determiner 30 to determine whether to provide a display to induce a following vehicle to avoid a vehicle, on the basis of vehicle information; and a controller 9 to cause an illumination light 10 to illuminate a rear road surface with light having illumination information that induces the following vehicle to avoid the vehicle when the avoidance determiner 30 determines to provide a display to induce the following vehicle to avoid the vehicle. Therefore, the rear-road surface illumination apparatus can indicate the existence of the vehicle to the following vehicle, to give the existence of the vehicle prominence, and can also make it easy to notify the driver of the following vehicle about what the driver of the vehicle desires the driver of the following vehicle to do.

The present disclosure relates to a driving assistance system, includes: a light detection and ranging module configured to detect position parameters of objects around the light detection and ranging module; a LiFi driving module connected to the light detection and ranging module and being capable of receiving the position parameters and modulating the position parameters to generate a LiFi signal; and a lighting module connected to the LiFi driving module, and configured to provide lighting and transmit the LiFi signal.

A planned trajectory is analyzed by an L4 emergency braking module, before the trajectory is navigated by the autonomous driving vehicle (ADV). An L4 emergency braking signal is generated in response to an autonomous driving vehicle (ADV) determining that any portion of a planned trajectory of the ADV has a deceleration that is less than −2 m/sec.sup.2 and a time to collision with the ADV, by a vehicle following the ADV at a speed Z and a distance Y<100 m, during a period of 1 to 8 seconds after time 0 of the planned trajectory, if

[00001]$\frac{T_X+Y}{Z}\le X$

for any time Xϵ{1 second . . . 8 seconds} after time 0, wherein T.sub.X is the location of the ADV in the trajectory at time X. Optionally, a sharp braking command can be issued by the L4 emergency braking module in response to activating the emergency braking signal.

The present invention obtains a processor and a processing method, a rider-assistance system, and a straddle-type vehicle capable of improving a rider's safety.

A processor (20) includes: an acquisition section that acquires surrounding environment information about straddle-type vehicle (100); a determination section that determines necessity of assistance operation executed by the rider-assistance system (1) to assist with the rider's operation; and a control section that makes an execution device (P) execute the assistance operation in the case where the determination section determines that the assistance operation is necessary. The determination section determines the necessity of the assistance operation by using a rear index value, which is an index value depending on information on the surrounding environment at the rear and is an index value of a collision possibility of an object located behind the straddle-type vehicle (100) against the straddle-type vehicle (100). The rear index value is a value that varies according to a relative distance and a relative speed of the object located behind to the straddle-type vehicle (100).

Disclosed is a warning system to be provided on a first vehicle, which includes a radar for measuring the distance D with a second vehicle that is following same, a display visible from the following vehicle, a unit for calculating the safety distance DS and a camera for reading the registration number of the second vehicle.

An attention calling device includes a memory and a hardware processor coupled to the memory. The hardware processor is configured to: acquire information regarding obstacles around a moving object detected by a sensor included in the moving object; calculate a potential risk that is a degree to which attention needs to be paid for each of the obstacles around the moving object, based on the acquired information regarding the obstacles and a moving state of the moving object; and present, to an occupant of the moving object, information for calling attention to an obstacle having a potential risk exceeding a predetermined value, based on a calculated potential risk of each of the obstacles.
