A car sickness inhibition device includes: a memory and a processor connected to the memory, the processor being configured to: acquire an acceleration a in a front-rear direction of a vehicle or angles of inclination θ of the head and upper body of an occupant sitting in a seat of the vehicle; and by using expression θ>tan.sup.−1(a/g).Math.(1), where g denotes gravitational acceleration, obtain from the acquired acceleration a an angle of inclination θ0 with which car sickness is inhibited, or obtain an acceleration a0 with which car sickness is inhibited.

A vehicle seat comprising: a seat base comprising a rigid frame, a flexible covering layer, as well as a cushioning layer interposed between the flexible covering layer and the frame, a backrest comprising a rigid frame, a flexible covering layer, as well as a cushioning layer interposed between the flexible covering layer and the frame, and a haptic system, comprising: at least one independent set each comprising at least one pneumatic haptic element, positioned at the backrest and/or the seat base, and at least one independent set each comprising at least one electromechanical haptic element, positioned at the backrest and/or the seat base.

A system for preventing sleep in vehicle operators can include a user device and a mat operatively connected to the user device and positioned on a driver-side floor of a vehicle. The mat can be configured to, via one or more processors, receive an enablement signal from the user device; and in response to receiving the enablement signal, cause a haptic effects generator to generate vibrations within the mat.

A child safety seat is provided and includes a base, a seat body and a notifying system. The seat body is movable relative to the base between a first position and a second position. The notifying system includes at least one actuated device disposed on one of the base and the seat body, an actuating component disposed on another one of the base and the seat body, and a notifying device electrically connected to the at least one actuated device. When the seat body reaches at least one of the first position and the second position, the actuating component actuates the at least one actuated device, so that the at least one actuated device is actuated to generate different types of actuating signals. The notifying device generates different types of notifying signals when the at least one actuated device generates the different types of actuating signals.

A device and a method for controlling a seat of a vehicle includes a detector for detecting vehicle environment information, a vibration generator mounted on the vehicle seat to generate the seat vibration, and a controller electrically connected to the detector and the vibration generator, and the controller detects seat environment information through the detector, determines a weight and a sitting posture of a user seated in the vehicle seat based on the seat environment information, determines a vibration pattern and a vibration excitation force based on the weight and the sitting posture of the user, and generates the seat vibration by controlling the vibration generator based on the determined vibration pattern and vibration excitation force.

A seat adjustment system for a vehicle seat is provided. The seat adjustment system includes a seat body; at least one actuating unit, configured to adjust a support of the seat body; a sensing unit, configured to obtain and provide seat information and body shape data of a back of an occupant; and a control unit, configured to control the at least one actuating unit; wherein when one parameter of the seat body changes, the control unit makes a portion of the body shape data of the occupant in a pre-defined range via the at least one actuating unit.

A method for the automatic operation of a vehicle in an autonomous driving operation requiring no user action by means of a driver assistance system involves informing a driver of the vehicle in good time about an imminent automatic intervention of the driver assistance system into longitudinal and/or transverse dynamics in the autonomous driving operation by way of an automatic emission of a notice.

Disclosed are an apparatus and a method for controlling a vehicle seat so as to control a seat back and a neck pillow based on a sound. The apparatus includes the vehicle seat installed in a vehicle and including a seat back and a neck pillow, a detector for detecting vehicle information and seat information, and a processor connected to the vehicle seat and the detector, wherein the processor determines a vehicle state and a seat sitting posture based on the vehicle information and the seat information, analyzes a sound being reproduced in the vehicle, determines a haptic pattern and a haptic pressure based on the vehicle state and the seat sitting posture, and the analysis of the sound, and controls the seat back and the neck pillow based on the determined haptic pattern and haptic pressure to provide a haptic effect.

A vehicle seat comprises at least one vibration device comprising an electroacoustic transducer, the vibration device having a mass less than or equal to 130 g.

A system for a vehicle includes a sensor configured to sense information associated with the vehicle's surroundings, environment and/or condition and output a sensor signal based on the sensed information, a processor configured to receive the sensor signal, determine haptic feedback for the system to display based on the sensor signal, and output a haptic control signal, and a haptic output device configured to receive the haptic control signal from the processor and generate the haptic feedback to a driver of the vehicle based on the haptic control signal.
