Object Detection Description and Operation (with Haptic Signal Motor Seat)

The Active Safety Seats provide a vibration in the driver's seat bottom cushion to alert the driver of a number of concerns. There are two motors providing the vibration and are located on the left and right sides. Depending on the alert, either the left, right or both motors will activate.

The Active Safety Seat is made up of the following components:

* Seat Memory Control Module

* Haptic Signal Motor - Driver Left Rear

* Haptic Signal Motor - Driver Right Rear

Seat Memory Control Module

The Seat Memory Control Module receives serial data messages from other modules and provides a voltage output to turn on the haptic signal motors. The Seat Memory Control Module will pulse the left, right, or both motors the number of pulses requested over serial data. The module monitors the circuits for open, short to ground, and short to voltage conditions and will set DTCs if a problem is detected. The modules that can request haptic motor operation are:

* Front and Rear Parking Assist Control Module (Front and Rear Parking Assist)

* Vehicle Camera Module (Lane Departure Warning, Forward Collision Alert)

* Side Object Sensor Modules (Rear Cross Traffic Alert)

Haptic Signal Motors - Driver Left Rear and Driver Right Rear

The motors are located in the driver's seat bottom cushion and are positioned on the left and right sides. The motors are connected to ground and receive voltage from the Seat Memory Control Module. There are no connectors other than at the Seat Memory Control Module.

Active Safety Seat Operation

System operation can be described by the following alerts:

* Front and Rear Parking Assist - when an object is first detected both motors will be pulsed twice. If a potential crash is detected, both motors will be pulsed five times.

* Lane Departure Warning - when the vehicle crosses a lane marking either the left or right motor will be pulsed three times depending on which side the warning is for.

* Forward Collision Alert warning - both motors will be pulsed five times.

* Rear Cross Traffic Alert - When backing up, if rear cross traffic is detected, either the left or right motor will be pulsed three times, depending on which side the warning is for.
