摘要： A system and method of hands-off signature detection may include applying a unique sinusoidal motor command to an EPS or handwheel actuator of a vehicle and monitoring attenuation of the unique sinusoidal motor command to determine if a user's hands are on or off of a handwheel of a vehicle. Attenuation of the unique sinusoidal motor command may occur due to the physical presence of a driver's hand(s) on the steering wheel.

摘要： According to the present embodiments, a torque applied to a torsion bar is attenuated to thus relatively increase the rigidity of the torsion bar, thereby improving the response performance to a driver's steering wheel operation, increasing a responsive torque range, securing the durability of components such as the torsion bar, and simplifying adjustment of the moving distance of a rack bar compared to the number of revolutions of the steering wheel.

摘要： A vehicle control apparatus includes a contact detector, an attitude stabilization processor, and a steering intention determining unit. The contact detector is configured to detect a contact of a vehicle with an object. The attitude stabilization processor is configured to execute an attitude stabilization control that generates a yaw moment at a vehicle body on the basis of a deviation between a target yaw rate and an actual yaw rate. The steering intention determining unit is configured to determine a presence of a driver's intention to perform steering. The attitude stabilization processor is configured to stop the generation of the yaw moment by the attitude stabilization control or reduce the yaw moment to be generated by the attitude stabilization control, in a case where the steering intention determining unit determines that the driver's intention to perform the steering is absent after the detection of the contact by the contact detector.

摘要： A torque detection device includes: a sensor case that receives a magnetic detector; and a cover that has a sensor cover portion and a rotor cover portion. The sensor cover portion is coupled to a surface of the sensor case which faces in an axial direction. The rotor cover portion is joined to the sensor cover portion and receives a rotor inserted in the rotor cover portion in the axial direction. Furthermore, the rotor cover portion limits movement of the rotor relative to the sensor case in a direction perpendicular to the axial direction.

摘要： An object can be detected in contact with a steering wheel of a vehicle. A first image of the steering wheel at a first angle of rotation and a second image of the steering wheel at a second angle of rotation are then obtained. A type of the object is identified based on at least one of the first image or the second image, as one of a human hand or a foreign object. A vehicle component is controlled based on the type of object.
