A seating detection method includes: detecting whether a seat belt sensor in a vehicle seat is in an ON state or an OFF state; detecting whether a pressure sensitive sensor in a seat skin constituting a seating surface is in an ON state or an OFF state; and determining a foreign object insertion state in which a foreign object is inserted between the seating surface and a child seat based on whether the seat belt sensor is in the ON state or the OFF state and whether the pressure sensitive sensor is in the ON state or the OFF state. When the pressure sensitive sensor is changed from the ON state to the OFF state in a state in which the seat belt sensor is maintained in the ON state after the seat belt sensor is changed to the ON state, it is determined as the foreign object insertion state.

A vehicle assembly includes a vehicle body and a driver seat. The vehicle body defines a driver compartment having a first door with a first window and a second door with a second window. The driver seat is disposed within the driver compartment. When the driver seat is in a position that accommodates an operator being in a 95.sup.th male height percentile, the operator within the driver seat can see out of (i) the first window at a first angle relative to a forward looking direction that is parallel with a longitudinal axis of the vehicle body and (ii) the second window at a second angle relative to the forward looking direction. Each of the first angle and the second angle is at least 95 degrees.

An occupant support system includes a vehicle seat and an electronics system for the vehicle seat. The electronics system includes a sensor system configured to obtain sensor data and a computer coupled to the sensor system to process the sensor data and perform a predetermined action using the sensor data.

A system includes a processor configured to determine the location of a wirelessly-identified device within a vehicle. The processor is also configured to determine a locking schema associated with the device for locking child-lockable vehicle systems and apply the locking schema to corresponding systems in a defined proximity to the determined device location.

A computing system for a vehicle is provided. The computing system includes one or more processors for controlling operation of the computing system, and a memory for storing data and program instructions usable by the one or more processors. The one or more processors are configured to execute instructions stored in the memory to determine if the vehicle is operating with at least one occupant inside the vehicle. If the vehicle is operating without at least one occupant inside the vehicle, the system may control the vehicle so as to disable and/or deactivate selected ones of driver-usage systems/components and passenger-usage systems/components.

At least one analog load sensor, such as a force sensitive resistor is situated between upper and lower seat structures to generate a signal correlating with weight placed upon the seat. A vehicle has multiple seats fitted with sensors. Weight related information is communicated to a processor and an optional display, along with seatbelt latch sensor outputs to communicate to an operator if any seats are occupied without seatbelt latched. A weight force threshold for each seat is adjustable in one embodiment to customize the system to accommodate occupants of different weights and non-occupant loads of different weights. Loading information for the vehicle, such as total weight of occupants and/or objects on the seats and location of these loads upon the vehicle can be calculated and utilized to ensure that gross vehicle weight rating and load center of gravity and related parameters are within acceptable ranges.

A vehicle includes a vehicle seat comprising a seat base structure and a seat back structure pivotally connected to the seat base structure. The seat back structure includes a central adjustable region, an inboard side adjustable region adjacent the central adjustable region and a outboard side adjustable region located adjacent the central adjustable region. The seat back structure includes a central proximity sensor located at the central adjustable region, an inboard side proximity sensor located at the inboard side adjustable region and an outboard side proximity sensor located at the outboard side adjustable region. A seat back structure adjustment apparatus includes a central region adjustable member that adjusts a configuration of the central adjustable region, an inboard side adjustable member that adjusts a configuration of the inboard side adjustable region and an outboard side adjustable member that adjusts a configuration of the outboard adjustable region.

A microcontroller uses a combination of several synchronized PWM outputs to generate a low distortion sine wave by summing the PWM outputs and filtering the summed signal. The sine wave is used as a guard voltage. The unknown impedance is measured by impinging the guard voltage on the sense electrode by a transistor connected in common base configuration and then transferring the sense current through the common base connected transistor to a transimpedance amplifier made out of a second transistor connected in common emitter configuration. The output voltage at the collector of the second transistor is measured by an ADC input of the microcontroller. The microcontroller translates the ADC output values into the unknown impedance to be measured by doing a software demodulation of the ADC output values. A reference impedance can be connected in parallel to the unknown impeder to eliminate gain errors of the signal sensing circuit.

A vehicle seat assembly including a vehicle seat mounted on a spring suspension system, the seat assembly having a safe mode into which it can be placed when the seat is unoccupied to avoid damage to the spring suspension system due to forces generated within the suspension system of an unoccupied seat. The seat assembly is configured to be placed in communication with a control system of an associated vehicle in which it is mounted and to invoke the safe mode in dependence on the vehicle being placed in a predetermined operating mode of the vehicle which is indicative that the seat will be unoccupied.
