Abstract: A vehicle driving operation support apparatus for a vehicle, includes a sensing section to sense a traveling condition of the vehicle including a surrounding condition inclusive of an obstacle around the vehicle; and a control section to calculate a risk potential for the vehicle in accordance with the traveling condition. The control section performs a support control to support the driver in accordance with the risk potential, performs a first assist control to restrain disturbance (such as vibration from a road) transmitted to the driver in accordance with the risk potential, and performs a second assist control to produce inducement simulating a condition change (such as a vehicle behavior) attributable to an increase of the risk potential, in accordance with the risk potential. The control section further performs a cooperation control to coordinate the first assist control and the second assist control.

Abstract: A motor vehicle includes a vehicle driving operation support system. The vehicle driving operation support system senses an environment surrounding the motor vehicle; senses a traveling condition of the motor vehicle; calculates a risk potential of the motor vehicle on a basis of the sensed environment and the sensed traveling condition; controls the motor vehicle on a basis of a control setpoint. The vehicle driving operation support system sets on a basis of the calculated risk potential the control setpoint to a provisional setpoint effective for reducing the risk potential; senses driver's operation in reaction to the controlling operation with the control setpoint set to the provisional setpoint; and sets the control setpoint to a normal setpoint on a basis of the sensed driver's operation.

Abstract: Under an automatic turning control, a steering controller defines a value of steering angle set according to a target turning angle of the automatic turning control, as a value of steering angle at which a reaction force is equal to 0. Thereby, the steering controller controls a steering reaction force on the basis of a difference between an actual steering angle and the value of steering angle at which the reaction force is equal to 0.

Abstract: A steering control apparatus is provided, including a steering wheel, steered wheels, a direction varying actuator to operate the steering control wheels, a steering reaction actuator to apply steering reaction torque to the steering wheel and steering controller. The steered wheels are mechanically disconnected from the steering wheel. The steering controller outputs control commands for controlling the direction varying actuator and the steering reaction actuator.

Abstract: A steering control system comprises a steering component, a turning component, and a backup mechanism for alternately mechanically separating and linking steering and turning components. A steer-by-wire control unit is provided for executing steer-by-wire control of a turning actuator to a turning angle corresponding to a steering condition and control of a steering reaction force actuator for imparting steering reaction force corresponding to the turning condition. A steering assistance control unit is selectively linked to the backup mechanism to executing steering assistance control for at least one of the steering reaction force actuator and the turning actuator. A control switching unit is provided for controlling a shift, under predetermined conditions, between control by the steer-by-wire control unit and control by the steering assistance control unit.

Abstract: A wiper apparatus (1) includes: a wiper blade (2a) driven by a motor (3a); and a wiper blade (2b) driven by a motor (3b). The motors (3a, 3b) are drive-controlled by control microcomputers (5a, 5b), respectively. The control microcomputers (5a, 5b) are connected to each other through a communication line (7). While exchanging position information of the wiper blades (2a, 2b) through the communication line (7), the control microcomputers (5a, 5b) synchronously drive the motors (3a, 3b) on the basis of a position relationship between both of the wiper blades. In the case where a communication abnormality occurs when the position relationship between the wiper blades (2a, 2b) is in a normal state, the wiper blade (2b) is stopped after reaching a lower turning position. In the case where the communication abnormality occurs in a state where the position relationship between the blades (2a, 2b) is inverted, the blade (2b) is stopped after reaching an upper turning position.

Abstract: A vehicle steering controller produces a steering system friction value and a tire lateral force value. A steering reactive force having a magnitude based on the tire lateral force value and the steering system friction value is generated for application to a steering wheel of the vehicle. By reflecting both the tire lateral force and the steering system friction in the steering reactive force, a good steering sensation can be realized in a steer-by-wire system.
