Abstract:
A collision mitigation controller drives a target brake to be controlled for assisting driver's collision-avoidance operation when a calculated collision time is less than an automatic brake a1 judgment line which is determined in advance. The controller drives the automatic brake a1 in order to mitigate damage generated by a collision with an obstacle or another vehicle when the collision time is less than an automatic brake a2 judgment line which is also less than the automatic brake a1 judgment line. The controller decreases the braking force for the automatic brake a2 when judged that the automatic brake a1 is not driven, as compared with the judgment where the automatic brake a1 is driven. When the automatic brake a2 drives the target brake, it is possible to avoid a collision where own vehicle is struck from behind by the rear vehicle which runs on a same traffic lane.
Abstract:
In a method for operating a preventive-action protection system in a motor vehicle having safety devices for lessening the consequences of accidents, driving state data are monitored and with respect to a state of emergency braking. At least one of the safety devices is triggered if a state of emergency braking is determined and confirmed by a plausibility check. For the plausibility check, at least the control state of an antilock brake system and one of the brake pressure is monitored.
Abstract:
A method and device serves to reduce damage caused by an accident, in which a vehicle driver is unable to bring the vehicle that has had an accident into a safe position. A system intervenes in an appropriate manner into the motional behavior of the vehicle, influencing the latter in such a way that the vehicle can be brought into a safe position without the cooperation of the driver (autonomously).
Abstract:
A system for use with a motor vehicle that minimizes injury after a loss of control event. The motor vehicle has at least one front wheel and at least one rear wheel and an engine. The system includes a control which detects a loss of control event and automatically actuates a brake system and/or a steering system and/or commands an engine controller to reduce power output of an engine.
Abstract:
A vehicle brake system includes a brake mechanism for individually braking wheels, and a brake controller for controlling the brake mechanism against an oblique collision from behind or an offset collision with a host vehicle. The controller includes a collision predictor, a collision direction detector, and a colliding object speed detector. In accordance with a prediction signal transmitted from the collision predictor, a detection signal transmitted from the collision direction detector and a detection signal transmitted from the colliding object speed detector, the controller controls the operation of the brake mechanism to allocate braking forces to the respective wheels so as to prevent the turning of the host vehicle in a collision.
Abstract:
The present invention relates to a braking device for vehicles capable of preventing any further accidents subsequent to an initial vehicle collision by automatically operating a parking brake upon the collision. The braking device of the present invention comprises a collision sensing means for sensing a vehicle collision and outputting a signal corresponding thereto, and an emergency braking means for causing a parking brake to perform a braking operation in response to the signal from the collision sensing means.
Abstract:
In a method and a control arrangement for minimizing the consequences of an accident for motor vehicles, an evaluating unit continuously evaluates environmental data supplied by environmental sensors and vehicle data supplied by a vehicle electronics unit in the light of characteristic features stored in a memory. As a result of this evaluation, it can be ascertained whether an unavoidable accident situation is present with respect to a detected obstacle in which case the evaluating unit performs a controlled braking of the individual wheels of the vehicle by way of a braking control and/or an automatic steering process. This process takes places in such a manner that an optimum speed reduction is achieved as well as a favorable angle of impact. An optimal angle of impact depends on vehicle-specific features and on the particular accident situation.
Abstract:
The braking system of a vehicle is securely engaged in response to the operator of the vehicle causing the vehicle to stop. The braking system improves vehicle safety by remaining securely engaged upon detection of a fault such as a vehicle collision, an unintentional transmission shift, a vehicle malfunction or a problem with the operator or operation of the vehicle. In the event of a collision, securely engaged brakes can significantly reduce resulting vehicle acceleration, potentially avoiding a secondary collision and reducing injuries experienced by the vehicle operator and passengers. In the event that no fault is detected, the braking system is disengaged in response to the operator accelerating the vehicle, either by pressing the gas pedal or releasing the brake pedal, thereby making the securely engaged brakes virtually unperceivable under normal operating circumstances. The braking system may be released rapidly in response to a substantially depressed gas pedal to facilitate a rapid start or gradually in response to a partially depressed gas pedal to facilitate a smooth start.

Abstract:
A system and method assist the driver of a motor vehicle in preventing accidents or minimizing the effects of same. In one form, a television camera is mounted on a vehicle and scans the roadway ahead of the vehicle as the vehicle travels. Continuously generated video picture signals output by the camera are electronically processed and analyzed by an image analyzing computer, which generates codes, that serve to identify obstacles. A decision computer mounted in the controlled vehicle receives such code signals along with code signals generated by the speedometer or one or more sensors sensing steering mechanism operation and generates control signals. Such code signals maybe displayed, and as synthetic speech or special sound generating and warning means used to warn the driver of the vehicle of approaching and existing hazards. The system may also use the control signals, particularly through application of fuzzy logic, to control the operation of the brakes and steering mechanism of the vehicle to avoid or lessen the effects of a collision. In a particular form, the decision computer may select the evasive action taken from a number of choices, depending on whether and where the detection device senses other vehicles or obstacles.
