A collision behavior control apparatus which comprises a contacting portion disposed in a portion of the front of a vehicle, and which, at the time of collision against a pedestrian or a two-wheeler with a rider riding thereon, controls the behavior of the pedestrian or the two-wheeler rider by pushing the pedestrian or the two-wheeler rider separated from the two-wheeler with the contacting portion, wherein the pedestrian or the two-wheeler rider is pushed by the contacting portion such that the pedestrian or the two-wheeler rider is not bumped up onto the hood, whereby the pedestrian or the two-wheeler rider is moved to the vehicle side.

A method of effecting an analysis of behaviors of substantially all of a plurality of real segments together constituting a whole human body, by conducting a simulation of the behaviors using a computer under a predetermined simulation analysis condition, on the basis of a numerical whole human body model provided by modeling on the computer the whole human body in relation to a skeleton structure thereof including a plurality of bones, and in relation to a joining structure of the whole human body which joins at least two real segments of the whole human body and which is constructed to have at least one real segment of the whole human body, the at least one real segment being selected from at least one ligament, at least one tendon, and at least one muscle, of the whole human body.

A collision discriminating apparatus for vehicles having a collision detection device mounted on a part of the vehicle to detect the deformed amount of a collided portion deformed by collision of a collision object against the vehicle, and a collision object presuming device for presuming what object collided against the vehicle on the basis of the deformed amount of the collided portion detected, and the vehicle speed when the vehicle collided.

Collision discriminating apparatus for vehicles

A rear wheel steer angle controlling apparatus for vehicles having steerable front and rear wheels, adapted for controlling the steer angle of rear wheels in response to the operation of the steering wheel for steering the front wheels. When the steering wheel is operated quickly, a rear wheel steer angle is formed in the counter direction to the direction of the front wheel steer angle, so that the response to the steering input for turning the vehicle is improved. Conversely, when the steering wheel is operated slowly, a rear wheel steer angle is formed in the same direction as the front wheel steer angle, thus enhancing the stability of the vehicle running straight. When the vehicle is running at a high speed, the rear wheel steer angle is formed always in the same direction as the front wheel steer angle regardless of the speed of operation of the steering wheel, so that the steering stability during high speed running is improved. When a yawing moment is generated due to a disturbance such as lateral wind, the rear wheel steer angle is automatically controlled in such a manner as to negate the yawing moment, thus compensating for the lateral displacement of the vehicle without requiring correcting steering operation by the driver.

Apparatus for controlling steer angle of rear wheels of vehicle

A rear wheel steer angle controlling apparatus for vehicles having steerable front and rear wheels, adapted for controlling the steer angle or rear wheels in response to the operation of the steering wheel for steering the front wheels. The speed with which the steering wheel is turned is detected and compared with a reference value which varies in accordance with changes in a physical amount related to the vehicle velocity. When the speed of operation of the steering wheel is larger than the reference value, a rear wheel steer angle is formed in the counter direction to the direction of the front wheel steer angle, so that the response to the steering input for turning the vehicle is improved. Conversely, when the speed of operation of the steering wheel is smaller than the reference value, a rear wheel steer angle is formed in the same direction as the front wheel steer angle, thus enhancing the stability of the vehicle running straight.

An apparatus for controlling steer angle of rear wheels of a 4-wheel steering vehicle in accordance with the operation of a steering wheel for generating steer angle of front wheels. The apparatus comprises a first member which moves in response to the operation of the steering wheel; a second member which moves in response to the operation of the steering wheel in a direction counter to that of the first member; an output shaft for controlling the steer of the rear wheels; a resilient member disposed between the first member and the output shaft and a controller disposed between the second member and the output shaft for controlling the direction of movement of the output shaft in accordance with the speed of operation of the steering wheel. When the steering wheel is operated at high speed, the resilient member absorbs the force from the first member so that the output shaft moves in the same direction as the second member, whereby the rear wheels are turned in a direction counter to that of the front wheels. When the steering wheel is operated at low speed, the force from the second member is damped so that the output shaft moves in the same direction as the first member, whereby the rear wheels are turned in the same direction as the front wheels.

The automotive tire being measured is loaded in advance by the load applying means, and the drum is driven to rotate the tire. A displacement of the rotatable shaft produced in response to a variation in the radial force acting between the tire and the drum is detected as a displacement of the movable member which is in turn indicated as the radial force variation generated on the tire. Thus, the apparatus can measure a radial force variation with precision under a condition approximating an actual running condition of automobiles.
