摘要： A method is disclosed for determining the steering center of a vehicle. The algorithm involves supplying power to a controller after ignition-off to save the steering wheel angle value that is stored in the controller's non-volatile memory. At ignition-on, the steering wheel angle value that was stored in the controller's non-volatile memory is retrieved and compared to a recently calculated probable steering wheel angle value. The recently calculated probable steering wheel angle value is calculated based on an offset compensated value of the vehicle's yaw rate and offset compensated value of the vehicle's lateral acceleration. If the difference between the value stored in the volatile memory and the recently calculated probable steering wheel angle value are within a predetermined range, the value stored in the non-volatile memory will continue to be used.

摘要： An electrical power-assisted steering system is disclosed comprising an electric motor connected through a gearbox to act on a steering mechanism of the vehicle, the electric motor having a plurality of phase windings connected to a star point and switching means provided in at least one phase of the motor, the switching means being movable between a closed position in which current is able to flow in the phase windings, and an open position which prevents current flowing in a respective phase winding. The system incorporates a safety circuit operative when a fault develops to smooth out the transition between the presence and absence of servo support in assisting and not assisting by providing a prescribed period of damped operation as part of a shut-down phase.

摘要： A vehicle includes a first actuating system having an automatic steering actuator to bring the front wheel steer angle to a calculated target front wheel steer angle for lane keeping, and a second actuating system such as a front and rear roll stiffness distribution control system, a front and rear driving force distribution control system, a rear wheel steering system, and a differential limiting force control system. By controlling the second actuating system in accordance with the automatic steering operation, a control unit adjusts the steering characteristic of the vehicle in a direction to improve the yawing response or in a direction to improve the running stability.

摘要： A vehicle attitude control apparatus, wherein a corrected behavior index value for steering is determined in such a manner that the deviation between a target behavior index value for a vehicle and a corrected behavior index value for steering decreases, as an instability index value correlating to the amount of under-steer increases, and when the target behavior index value and the behavior index value are equal, the corrected behavior index value for steering is set to equal the behavior index value. A corrected behavior index value for braking is determined in such a manner that the deviation between the target behavior index value and a corrected behavior index value for braking increases, as the instability index value increases, and when the target behavior index value and the behavior index value are equal, the corrected behavior index value for braking is set to equal the behavior index value. The steering actuator and braking forces are controlled in such a manner that, when not in the state of under-steer, the behavior index value follows the target behavior index value, and when in the state of under-steer, the corrected behavior index value for steering and corrected behavior index value for braking follow the target behavior index value.

摘要： A steering system for a motor vehicle with at least one steerable wheel, an actuator, and an auxiliary drive. The steering motion initiated by the driver of the vehicle and the motion initiated by the actuator are superimposed by the auxiliary drive to generate the steering motion of the steerable wheel. At least two steering components are computed and a control signal is generated to control the actuator by superimposing the computed steering components. The steering components are computed in parallel and independently of one another so that several functions are beneficially combined to control running behavior. This provides an improvement of running dynamics by means of steering interventions.

摘要： A supplemental steering system is provided for a machine having first and second brakes actuable for slowing rotation of first and second drive outputs or wheels, a brake actuator, and a main or primary steering system. The brake actuator is connected with a first port and a second port of a supplemental steering control valve having a first chamber and a second chamber. The first port communicates with the first chamber and the second port communicates with the second chamber. The supplemental steering control valve further includes a piston located in the bore connected to a steering input and having a neutral position generally equidistant between the first and second chambers. First and second brake ports respectively communicate the first and second chambers with the first brake. The piston is movable in a first direction a predetermined distance into the first chamber to close the first port such that further movement of the piston in the first direction will urge brake fluid in the first chamber through the first brake port to actuate the first brake, and movement of the piston in a second direction actuates the second brake.

摘要： An omni direction vehicle with a frame having a round surface about its perimeter with no apparatus mounted on the frame extending beyond the perimeter. Two independent drive wheels located on an axis through the center of the frame are mounted at the same distance from a central vertical axis through the frame. Each wheel is powered independently of the other and can rotate at variable speeds in either direction. The vehicle is capable of movement in any direction by rotating the axis of the drive wheels to a position which is perpendicular to the desired direction of travel. The vehicle can spin about its vertical axis such that the axis of the drive wheels can be oriented at any direction without changing the original footprint of the space that the frame occupies over the ground. Thus, the vehicle requires a zero turning radius and requires only the space it occupies to change its forward orientation.
