Figure 3 that are receiving power have lost traction. When the traction control system determines that one wheel is spinning more quickly than the others, it automatically "pumps" the brake to that wheel to reduce its speed and lessen wheel slip. In most cases, individual wheel braking is enough to control wheel slip. However, some traction ontrol systems also reduce engine power to the slipping wheels. On a few of these vehicles, drivers may sense pulsations of the gas pedal when the system is reducing engine power much like a brake pedal pulsates when the antilock braking system is working. Automotive Occupant Detection system detects loading force on the front passenger seat and classifies the seat as empty or the occupant as an adult or infant/child. The ECU processes the sensor data and provides a deployment-allowed output to the vehicle’s sensing and diagnostic module when a defined threshold is met. It helps to reduce the potential for airbag-induced injury and allows airbag suppression when seat is empty, occupant is below defined threshold and for children Allows airbag deployment when 5th percentile female and larger adults are present.
