摘要:
The present teachings provide for an active steering system for controlling a vehicle (10). The system can include at least one sensor (50) and a control module (58). The at least one sensor can be configured to detect a leading obstacle (226). The control module can be configured to receive a signal from the at least one sensor, to determine a steering profile (286), and to execute a lane change maneuver based on the steering profile. The steering profile can include a plurality of steering angles (110) and corresponding vehicle positions for maneuvering the vehicle from a current lane (218) to an adjacent lane (222). The steering angles can be calculated to not increase the acceleration of the vehicle above an occupant comfort threshold value and to not cause the vehicle to cross an outer boundary (262) of the adjacent lane.

A sensor abnormality detection device (1) includes a first sensor (3a) that detects a situation of a first region at a periphery of an own vehicle; a second sensor that detects a situation of a second region, which is a region different from the first region and includes an overlapping region that overlaps a part of the first region; a sensor abnormality determination means (1e) that determines abnormality of the first sensor and the second sensor; and a collision detection means (1d) that detects collision of the own vehicle to an object; wherein the sensor abnormality determination means determines that at least one of the first sensor and the second sensor has abnormality when the first region and the second region do not overlap in the overlapping region after the collision is detected.

An object detection apparatus includes a light illumination unit that emits illuminating light; an imaging unit that captures a first image of distant photographic subjects by detecting lights from the photographic subjects, captures a second image of foreign matter attached to a monitoring area by detecting the illuminating light reflected from the foreign matter, and generates an image frame; a target detection unit that detects a detection target among the distant photographic subjects based on the first image; a foreign matter detection unit that detects the foreign matter based on the second image; and an exposure amount change unit that changes an exposure amount of the imaging unit. The target detection unit detects the detection target using plural imaging frames with different exposure amounts. The foreign matter detection unit detects the foreign matter using the imaging frame other than the imaging frame with the greatest exposure amount.

Le procédé de pilotage automatique d'un véhicule comprend une étape (100) initiale dans laquelle sont données une trajectoire locale de référence et une vitesse potentielle (v) du véhicule. Une étape (120, 121, 140) de calcul d'une consigne automatique d' angle de braquage (δcar) permet de calculer une accélération latérale (a ykin ) proportionnelle au carré de la vitesse potentielle (v) du véhicule en faisant décrire au véhicule un arc de cercle comportant un point d'intersection avec la trajectoire locale de référence à une distance (Id) du véhicule. Une étape (181) consiste à générer d'une consigne de vitesse (vr) positionnée à une valeur égale à celle de la vitesse potentielle (v) lorsque l'accélération latérale (a ykin ) a une valeur inférieure à une valeur maximale admissible d' accélération latérale (a y max ) et une étape (167) d'ajustement consiste à diminuer la valeur de la vitesse potentielle (v) lorsque l' accélération latérale (a ykin ) a une valeur supérieure ou égale à la valeur maximale admissible d' accélération latérale (a y max ) de façon à calculer une accélération latérale (a ykin ) diminuée en réitérant ladite étape (120, 121, 140) de calcul.
摘要:
A vehicle, such as an automobile, is provided with friction (1) and regenerative (3,4,5) braking systems. A sensor (15) detects an obstacle in the vehicle's path and a brake controller (5), when operated by a user, automatically deploys either or both braking systems to decelerate the vehicle so that its speed corresponds to that of the obstacle when the vehicle is a predetermined distance from the obstacle. The brake controller is arranged to deploy the braking systems in order to optimise recovery of kinetic energy by the regenerative braking system. The brake controller may be operated in a standard mode, in which it deploys the braking systems to provide a retarding force on the vehicle which depends on a driver's input. The brake controller may be controlled by a brake pedal (9). The pedal may have a position part way along its travel at which resistance to further travel temporarily increases and operation of the pedal beyond that position causes the brake controller to operate in the standard mode.

Autonomous short distance manoeuvring with optimal acceleration for avoiding or mitigating inevitable side and read end collision is a highly time sensitive design and technique that actively monitors, instantaneously senses inevitable or imminent side impact and rear end collision, alert or warns the driver and if the driver not available or doesn't react or if the drivers sensing and reaction time is not sufficient the present system according to scenarios acts in the right time to takes control of the vehicle's with autonomous optimal acceleration and steering followed by deceleration or restoring the control back to driver based on scenarios thereby mobilising the vehicle to short distance according to critical situations thus efficiently utilising the space around the vehicle to manoeuvre, locate or position the vehicle ultimately to avoid or mitigate the side impact and read end collision. The present system particularly helps in efficiently utilising the space or environment around the vehicle in critical situations ultimately to avoid or mitigate Imminent and inevitable side impact and rear end collision. The system smartly senses, perform context aware computing in a closed loop processing manner thereby autonomously and optimally accelerate and steer the vehicle to right position ultimately to avoid or reduce the side and read end collision thus assist in overcoming or mitigating critical situations for protecting the vehicles, occupants, pedestrians and other objects around or on the way. Also according to design, configurations and scenarios the system instantaneously restores or transfers the control back to the driver after the vehicle overcomes the critical situation or restores the vehicle position. In critical situations SAAAMS performs sensing, warns or alerts, performs pre computing & set ready to control the vehicle's acceleration prior to critical situation, current computing for controlling the vehicle's acceleration during critical situation, post computing to either stop or transfer the control back to the driver after overcoming the critical situation all accordingly to design, configuration and scenarios. The present system utilise smart and adaptive closed loop processing algorithm with predetermined and tested correlation table parameters to instantaneously check and compare the effects between predetermined and tested real world scenarios to the actual real world scenarios for actively sensing, computing and controlling the vehicle accordingly to mitigate the critical situations. In case of vehicles available in both front and rear end and if the rear end vehicle is about to collide the system actively senses, instantaneously manoeuvre the vehicle ultimately to efficiently utilises the space available between the own vehicle and front end vehicle thereby to provide space for the rear end vehicle that is about to collide to either stop or in extreme situations mitigates the severity of the collision.

摘要:
A vehicle (100) includes a support control unit (111) that supports avoidance of a. collision with an object and a support suppressing unit (112) that suppresses the support of the support control unit (111) when a steering angle of the vehicle (100) is equal to or greater than a predetermined angle. The vehicle (100) further includes an intervention limiting unit (113) that determines whether the support suppression of the support suppressing unit (112) is necessary when the steering angle is equal to or greater than the predetermined angle on the basis of vehicle information acquired from the vehicle (100) or a running environment of the vehicle (100) and that limits intervention of the support suppression of the support suppressing unit (112) depending on the determination result.
