The steering support member is disposed in a front portion of a vehicle cabin to support the steering column. The steering support member includes a steering support member body that extends in a vehicle width direction, and side brackets that fix both ends of the steering support member body to a vehicle body. The steering support member body is disposed above a gravity center position of the steering column to fix the gravity center position or a position in a vicinity of the gravity center position. At least the side bracket closer to the steering column includes a front-and-rear fixing portion that fixes the steering support member to the vehicle body in a vehicle front-and-rear direction.

A knee protector for a vehicle in which an upper bracket which generates a high reaction force to a knee input load and a lower bracket which generates a reaction force lower than the upper bracket are directly or indirectly attached, in a vertical position, to a vehicle body strength member. At least the upper bracket has a closed cross-section part on at least a part of the upper bracket. An inwardly protruding part which inwardly protrudes is formed in at least one surface of the closed cross-section part.

A vehicle motion control system is capable of defining clear guidelines on more specific control timing associated with accelerating, steering, and braking operations, and conducting motion control based on the defined guidelines. An ideal motion control unit within a central controller uses longitudinal jerk information of a vehicle to control the steering of the vehicle. Information for determining the initiation timing of steering is presented from a human-vehicle interface (HVI) to a driver. In accordance with the information presented from the HVI, the driver controls the initiation timing of steering.

To provide a vehicle motion control system capable of defining clear guidelines on more specific control timing associated with accelerating, steering, and braking operations, and conducting motion control based on the defined guidelines. An ideal motion control unitwithin a central controlleruses longitudinal jerk information of a vehicle to control the steering of the vehicle. Information for determining the initiation timing of steering is presented from a human-vehicle interface (HVI)to a driver. In accordance with the information presented from the HVI, the driver controls the initiation timing of steering.

In a motion control system for a vehicle including control means for controlling a yaw moment of the vehicle; first detection means for detecting a longitudinal velocity (V) of the vehicle; second detection means for detecting a lateral jerk (Gy_dot) of the vehicle; and third detection means for detecting a yaw angular acceleration (r_dot) of the vehicle, the yaw moment of the vehicle is controlled by the control means so that a difference between the yaw angular acceleration (r_dot) detected by the third detection means and a value (Gy_dot/V) obtained by the lateral jerk (Gy_dot) of the vehicle detected by the second detection means by the longitudinal velocity (V) detected by the first detection means becomes small.

In order to fit a driver's driving feeling, a vehicle speed control system includes a unit that calculates the instantaneous curvature and a unit that controls vehicle speed. The system reduces the vehicle speed when the instantaneous curvature tends to increase, and enhances it when the instantaneous curvature tends to decrease.

Provided is a control system that assists the vehicle operator in avoiding an obstacle by making use of simple information on the surrounding environment, and the effectiveness of such a system was demonstrated by computer simulations. The lateral acceleration that would enable the vehicle to avoid an obstacle is converted into a target yaw rate, and this contributed to the improvement in the property of a man&mdash;vehicle system in avoiding an obstacle. The target yaw rate can be relatively easily achieved by controlling the fore-and-aft forces of the tires. In particular, by including a phase advance in the target yaw rate, the responsiveness of the evading motion can be increased and the stability of the vehicle can be improved at the same time.

Vehicle operation assist control system

In a vehicle operation assist control system for assisting a vehicle operator to operate a vehicle, a distance to the obstacle and a width of the obstacle are detected by a radar or the like, and, when an obstacle is detected, the system determines an evasion path and accordingly modifies the map information available to the system. Therefore, the system, being aware of the situation, would not interfere with the vehicle operator taking an evasive action. The evasive path may be defined as a curvature which changes as a sinusoidal mathematical function of the position of the vehicle along the path. The control system may be based on a yaw rate control or a vehicle side slip angle control.
