A controller for controlling a haptic feedback actuator of a vehicle, the controller comprising: at least one input for receiving: vehicle parameter information being information indicative of a current value of at least one parameter associated with the vehicle; and information indicating that it is required to provide haptic feedback, a processor being arranged, in response to receipt of information indicating that haptic feedback is required, to generate a control signal for controlling operation of the haptic feedback actuator, the control signal being responsive at least in part to the vehicle parameter information; and an output for outputting the control signal.

A seat actuation control system includes at least one seat having a plurality of seat devices and a plurality of control modules interconnected over a communication bus. Each module is associated with a corresponding seat control device and is configured to control its corresponding seat device. Each module includes a processor and a memory coupled to the processor and storing program instructions therein which include receiving a status packet from each of the other control modules over the communication bus, processing the status packet for updating the overall system status, and actuating the seat device based on the overall system status. The program instructions further include determining status of the corresponding seat device, generating a status packet including the status information, and broadcasting the status packet to the other modules over the communication bus.

An on-board vehicle occupant weighing technology includes a simplified vehicle occupant weighing apparatus based on the discovered horwest effect and weighing moderator. The simplified weighing apparatus utilizes a weighing unit connected to the car seat of the vehicle occupant and a further weighing moderator, which provides convenient weighing of the foot part of the occupant's body by the same weighing unit that is connected to the car seat. The technology employs several methods of the weight measurements provided by different moderator approaches. The technology, methods, and simplified weighing apparatus are employed in on-board vehicle overweight and obesity preventing system wherein a weight trend analyzer provides predicting possibility of the occupant's overweight or obesity in a short predetermined period of time and automatically warning a vehicle occupant and a health care provider of the condition. The technology may also provide an accurate and convenient occupant's weight measurement in the vehicle safety devices such as seat belt and air bag Supplemental Restraint System (SRS system) to improve the Occupant Classification System to prevent possible extra force applied to the occupant's body in case of collision.

The present invention discloses a mm-wave radar sensor to be deployed in the vehicles for seat occupation detection applications. The key system relevant components are utilization of mm-wave integrated radar, specific planar high-gain antenna radiation pattern, and analyzing of the heartbeat and optionally also respiratory dynamics. The method of operation calculates probability of the seat occupation event regarding: detection of the passenger on the seat, detection of a baby or a child on the seat, detection of the presence of a baby or a child in the vehicle after the driver has left the vehicle, detection of the human or animal presence of intrusion in specific vehicle environment. In case that probability is above a predefined threshold, typically the interaction with vehicle control system is initiated using arbitrary automotive interfaces. Corresponding predefined actions are taken in that case. The predefined actions could be one or combination of the following: audio signal alerts to driver, inside cabin light condition change, engine operation condition change, opening of the windows or corresponding communication using arbitrary wireless means to outside vehicle environment. Optionally, the system is utilizing additional parameters like vehicle cabin temperature and/or timing information about engine stop and driver leaving the car. Preferably, the system is using 60 GHz or 77-79 GHz integrated radar front end working in Doppler operation mode, with 44 Tx and Rx planar radiation elements, with physical size typically in the range 421 cm, or smaller.

An alarm system can remind or alert an adult about the presence of a child in a vehicle. A child detector, such as a weight sensor or weight-activated circuit, can detect whether a child is occupying the child safety seat. The child detector may be integrated with or coupled to a child safety seat. The child detector can be used in coordination with a vehicle alarm system to remind or alert a driver that a child is occupying the child safety seat when a key is not in the ignition.

One variation of a method for renting a vehicle includes: receiving a signal from a fleet manager, the signal specifying a current availability of the vehicle for rent; updating a visual indicator arranged on the vehicle according to the signal, the visual indicator visually detectable from outside the vehicle; receiving identification information of a user proximal the vehicle; enabling access to the vehicle for the user in response to verification of the user as a driver of the vehicle; determining, through a sensor arranged within the vehicle, that the user is seated in a driver's seat within the vehicle; and enabling ignition of the vehicle for the user in response to determination that the user is seated in the driver's seat.

A motor vehicle with a seat unlocking system includes a seat with a seat part and a back part secured to a body at an attachment, an airbag, and an actuator for releasing the attachment of the seat to the body. Following activation of the actuator, the attachment between the seat and the body is disconnected such that the seat is moveable relative to the body. A control unit is configured to activate the actuator following an accident exclusively in the case of an opened airbag and exclusively with the motor vehicle at a standstill.

Systems, devices, and techniques are provided for occupancy assessment of a vehicle. For one or more occupants of the vehicle, the occupancy assessment establishes position and/or identity for some or all of the occupant(s).

A child safety seat 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 an actuated device, an actuating component and a notifying device. The actuated device is disposed on one of the base and the seat body. The actuating component is disposed on another one of the base and the seat body and configured to actuate the actuated device when the seat body reaches the first position or the second position. The notifying device is electrically connected to the actuated device and configured to generate a notifying signal in response to the actuated device when the seat body reaches the first position or the second position. The notifying signal indicates a child information for allowing a caregiver to determine whether the seat body is correctly used.

An example embodiment of a system and methods for detecting and reporting whether passengers are seated and secured in their seats within a vehicle may include a passenger sensor configured to provide an output indicative of a presence of a passenger in a seat in a vehicle, a restraint sensor configured to provide an output indicative of a status of a passenger safety restraint associated with the seat, a transmitter configured to be in electronic communication with the passenger sensor and the restraint sensor and to wirelessly transmit data indicative of the presence of a passenger in the seat and the status of the restrain, and a reporting module configured to be disposed proximate a driver of the vehicle. The reporting module may be configured to receive the data from the transmitter, and output a respective status for each of a plurality of seats.
