A system and method assists 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 may be displayed, and a 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.

Motor vehicle warning and control system and method

An AI-based adaptive vehicle control system which controls the speed of a vehicle in accordance with the driving characteristics of the driver. In effecting the follow-up driving which corresponds to the driving characteristics of the driver, the vehicle environment such as the distance between the vehicle and the vehicle in front, the relative speed, and the relative position, and the running state such as the speed and the steering angle of the vehicle itself are detected, and a danger index is calculated from the detected vehicle environment and running state in accordance with the driver's sense of driving. The danger index is calculated by the fuzzy induction from the membership functions which are determined in advance in accordance with a general driver's sense of driving. The running state of the vehicle such as the speed is controlled in accordance with the danger index. When the manipulated variable is changed by the driving operation of the driver, the danger index is adjusted in accordance with the amount of change. The change by the driving operation of the driver is reflected as the change in the membership functions. Thus, the calculated danger index gradually agrees with the driving characteristic of the driver.

In recent years, the development of the adaptive cruise control (ACC) system with the aim to improve driving convenience and comfort, has been progressing. To put this ACC system to practical use, the elimination of unexpected acceleration or deceleration caused by incorrect judgment is highly demanded. From 1997, the Laser Radar ACC system has been produced for the domestic version of the Lexus LS400. It provides high recognition capability with a two-dimensional scanning technology at an affordable price. This paper introduces this Laser Radar with a high-performance two-dimensional scanning technology.

A follow distance control apparatus controls a follow distance without giving an uncomfortable feel to a driver during a deceleration control regardless of a selected control mode. A front-vehicle running ahead of an own-vehicle is detected by a sensor such as a radar. A deceleration apparatus, which decelerates the own-vehicle, is controlled by a controller based on an output signal of the sensor. The controller controls the deceleration apparatus according to selected one of a short distance control mode and a long distance control mode. In the short distance control mode, an actual value of the following distance is controlled to be shorter. In the long distance control mode, the actual value of the following distance is controlled to be longer. The controller also controls the deceleration apparatus so that, when the long distance control mode is selected, an overshoot that is a phenomenon in which the own-vehicle moves excessively toward a near side of the front-vehicle is permitted more than when the short distance control mode is selected.

An alarm device generates an alarm when a distance between a vehicle and an object that exists in a set region in front of the vehicle is smaller than a set distance. A controller of the alarm device determines a tentative set distance based on at least one of a running speed of the vehicle and a relative velocity between the vehicle and the object, and then corrects the tentative set distance based on at least a deceleration of the vehicle, so as to determine a final set distance.

A vehicle operation control apparatus for controlling a running state of a vehicle based on a relative positional relationship between the vehicle and a preceding vehicle running in a predetermined area ahead of the vehicle. The vehicle operation control apparatus comprises a controller that determines a target deceleration of the vehicle based on the relative positional relationship between the vehicle and the preceding vehicle. The controller controls a deceleration of the vehicle so that the deceleration of the vehicle approaches the target deceleration and maintains the target deceleration until a predetermined condition is satisfied.
