  • Patent number: 7602311
    Abstract: A vehicle distance measuring safety warning system and method is disclosed having one or more distance measurement sensors measuring the distance from the driver's vehicle to a second vehicle immediately in front. A vehicle distance alarm alerts the driver when the distance between the driver's vehicle and the second vehicle is less than a configured minimum distance, indicating an unsafe driving condition. An event record display device displays the time/date or the last twenty occurrences of the distance warning alarm. When an alarm is generated, a throttle set-back actuator operates to gently and automatically slow the car and increase vehicle to vehicle distance. Vehicle brakes may be automatically applied by the system to further slow the vehicle. The vehicle distance measuring safety warning system provides an additional margin of safety for a driver who may be distracted while driving.

  • Publication number: 20090234552
    Abstract: A driver model with higher precision is created as an evaluation standard for a driving condition in a normal condition. Further, a driving action is estimated using a driver model which can be created easily and can represent driving characteristics of a driver more precisely. By detecting biometric information of a driver, whether a driver is in a usual condition or not is recognized. Then, data of driving conditions (own vehicle information such as, for example, operation amounts of accelerator, brake, and steering wheel, vehicle speed, inter-vehicle distance, acceleration, and the like) are collected while the driver is driving, and from the driving condition data, a part indicating that the driver operates in a usual condition is extracted to create a driver model. Thus, without making the driver aware, a driver model for normal times can be created automatically.

  • Publication number: 20090105922
    Abstract: A running control apparatus for controlling a running state of a vehicle by adjusting acceleration and deceleration of the vehicle releases the running control in case of a predetermined steering operation or more while the vehicle is stopped during the running control. This prevents the vehicle from running in a direction not intended by a driver at the time of starting, and the driver can be prevented from feeling a sense of discomfort at that time. Preventing the vehicle from starting in the direction not intended by the driver can also improve the running safety. This can restrain the vehicle from running in a way not intended by the driver upon a steering operation while the vehicle is stopped.

  • Publication number: 20090093938
    Abstract: In a vehicle speed control system, a preset offset distance is taken as a zero value of an inter-vehicle distance in a brake discriminant. When the current value of a corrected distance condition evaluation index is higher than the brake discriminant, a value on the brake discriminant is set as a target value of the corrected distance condition evaluation index. Deceleration control is started to decelerate the subject vehicle so that the deceleration of the subject vehicle becomes equal to the target deceleration of the subject vehicle computed based on the target relative speed corresponding to the set target value and the actual relative speed.

  • Publication number: 20090076702
    Abstract: In order to be able to undertake a reliable prediction of a movement trajectory of an object moving in road traffic even for relatively long prediction periods, a method is proposed in which there is firstly determined (203) with the aid of an evaluation of a determined movement variable of the object a driving maneuver that is executed by the object. A model (2051; . . . ; 205N) of the movement of the object is then selected as a function of the determined driving maneuver, and the movement trajectory of the object is calculated with the aid of the selected model. There is also proposed an apparatus for predicting the movement trajectory of an object that is suitable for carrying out the method. The object can be both a motor vehicle and an object in the surroundings of the motor vehicle.
