摘要: A system for controlling running safety of a vehicle having an alarm and an automatic braking system. A plurality of decelerations &agr;2n of an obstacle such as another vehicle present ahead on the road is predicted and corresponding manipulated variables &agr;1n (braking amount) to be supplied to the vehicle which indicate possible deceleration of the vehicle are determined. Then threshold values L&agr;2n for alarming and automatic braking are determined corresponding to the predicted deceleration and are successively compared with the distance to the obstacle. When the distance falls below any of the threshold values, alarming or automatic braking is effected to avoid contact with the obstacle, thereby making the system relatively simple and enabling operation to match the driver's expectations.

摘要: In a vehicle safety running system, while a contact probability estimation section estimates that there is a probability that a subject vehicle comes into contact with an object and an automatic braking section performs automatic braking, when the driver voluntarily performs a steering operation to avoid the contact, an automatic braking cancellation gradient is calculated based on the contact probability detected with the contact probability estimation section and the steering operation amount detected with the steering operation amount detection section, whereby automatic braking is cancelled at a speed corresponding to the automatic braking cancellation gradient so calculated. When the contact is easily avoided through the steering operation, the automatic braking cancellation gradient is set large so as to cancel automatic braking quickly, while when the contact is difficult to be avoided, the automatic braking cancellation gradient is set small so as to cancel automatic braking moderately.

摘要: A system for controlling running safety of a vehicle having at least a brake, a steering mechanism manipulated by a vehicle operator, a laser radar for detecting an obstacle present ahead on a course of travel of the vehicle, and a brake actuator mechanism actuating the brake independently of the vehicle operator manipulation. In the system, a first threshold value (defined in terms of relative distance between the vehicle and the obstacle) for avoiding contact with the obstacle by steering and a second threshold value for avoiding contact by operating the brake actuator mechanism are determined and are compared with the detected relative distance. When the detected relative distance is less than the first threshold value, the brake actuator mechanism is immediately operated to generate a relatively small deceleration, thereby enabling effective obstacle avoidance to well meet the intention and desires of the vehicle operator, without causing a problem of interference with the steering of the vehicle operator, while preventing the control accuracy from being degraded.

摘要: When a radar device S1 detects an object existing ahead of a vehicle in the movement direction of the vehicle, a determining device M1 determines a possibility of contact of the vehicle with the object from the relative positional relationship between the vehicle and the object, based on the result of such detection. If it is determined there is the possibility of contact, an automatic braking device M2 operates a vacuum booster 2 to carry out an automatic braking operation to avoid the contact of the vehicle with the object. When a braking-will detecting device M3 detects a driver's braking will during the automatic braking operation by the automatic braking device M2, an emergency-degree presuming device M4 presumes a degree of emergency in the driver's braking will, and the automatic braking device M2 generates the braking force corresponding to the degree of emergency to assist in the braking operation of the driver. This enables a smooth switch-over from the avoidance of the contact by the automatic braking operation to the avoidance of the contact by the driver's braking operation, and a high braking force assisted by the automatic braking operation can be generated to effectively avoid the contact.

摘要: A vehicle control system having a laser radar for detecting an obstacle present ahead on a course of travel of the vehicle; and control device for operating a brake or an alarm based on an output of the laser radar when a distance from the vehicle to the obstacle is less than a first predetermined value or is less than a third predetermined value. In the system, a millimeter-wave radar, which is inferior to the laser radar in position detection accuracy, but is superior in weather-proof operation, is provided. When the laser radar is inoperative, the control device operates the brake or alarm based on the output of the millimeter-wave radar when the distance is less than a second predetermined value (less than the first predetermined value) or is less than a forth predetermined value (greater than the third predetermined value), thereby expediting the alarm initiation to alert the vehicle driver at an appropriate time, while ensuring the proper brake initiation, so as not to cause the vehicle driver to experience annoyance.

摘要: The accuracy of determination of a possibility of collision of a vehicle with an object is enhanced without the shortening of a period for detection of the object by an object detecting apparatus. A collision-possibility determining device determines the presence or absence of a possibility of collision of the vehicle with the obstacle by comparing a future locus of movement of the obstacle determined by an obstacle locus determining device based on an output from a radar device, with a future locus of movement of the vehicle determined by a vehicle locus determining apparatus based on outputs from wheel speed sensors and a yaw rate sensor. The period of the detection conducted by the radar device providing data about the obstacle to the obstacle locus determining apparatus is 100 msec, but the obstacle locus determining apparatus, the vehicle locus determining apparatus and the collision-possibility determining apparatus carry out the determination of the possibility of collision at a determination period shorter than the detection period of 100 msec. Thus, it is possible to carry out the determination of the possibility of collision at the shorter determination period without use of a large-sized and expensive radar device, thereby enhancing the determination accuracy.

摘要: A vehicle travel safety device carries out automatic braking in order to prevent a subject vehicle from coming into contact with an object, and proximate expansion of an air bag is reliably prevented. When there is a possibility of a subject vehicle coming into contact with an object, automatic braking is carried out in order to prevent the contact. If a seat belt wear state sensor detects that an occupant is not wearing a seat belt and an air bag expansion possibility estimating means estimates that there is a possibility of an air bag expanding, by means of an automatic braking means, the deceleration rate of the automatic braking is reduced so that the occupant is prevented from moving forwards due to the inertia accompanying the braking and causing proximate expansion. When the speed of the subject vehicle at the time when automatic braking is started is high, the relative speed between the subject vehicle and the object at the time when automatic braking is started is high. Thus, the time taken for the subject vehicle to come into contact with the object is short or the speed of the subject vehicle at which it will come into contact with the object is high. Therefore, the air bag expansion possibility estimating means estimates that there is a possibility of the air bag expanding.

摘要: When the behavior of a vehicle becomes unstable during an automatic braking operation for avoiding contact of the vehicle with an object, the restoring of the unstable state backed up to effectively avoid the contact of the vehicle with the object. When a radar device in the vehicle, detects the object exist ahead of the vehicle in the direction of movement of the vehicle, the possibility of the contact of the vehicle with the object is determined by a determining device from the relative positional relationship between the vehicle and the object, based on the result of the detection. When it is determined that there is the possibility of the contact, an automatic braking device operates a vacuum booster to carry out an automatic braking operation. When the unstable state of the vehicle is detected by an unstable state detector during the automatic braking operation by the automatic braking device, the automatic braking device forcibly continues the automatic braking operation, until the vehicle reaches a state in which the unstable state is not detected, whether or not it is determined that there is the possibility of the contact of the vehicle with the object. Thus, it is possible to precisely control the continuation and finishing of the automatic braking operation to reliably achieve the avoidance of the contact of the vehicle with the object, while preventing the behavior of the vehicle from further becoming unstable due to the discontinuation of the automatic braking operation.

摘要: A vehicle control system for detecting an obstacle present ahead on the road in the course of travel of a vehicle, comprising a first laser radar mounted on the vehicle which emits an electromagnetic beam to detect the obstacle present ahead on the road, and second and third laser radars which measures distances between the first laser radar and the road surface at different angles. The system determines whether the first laser radar is mounted on the vehicle such that the laser beam central axis is horizontal or inclines upward or downward relative to the road surface or vehicle body, based on the distances, a height of the first laser radar from the road surface, the angles at which the distances are measured and reference values. The system may correct the inclination if determined. With the arrangement, the system ensures detection of an obstacle on the road without fail and conduction of a desired obstacle avoidance control.
