Anti-lock Braking System (ABS) means a portion of a service brake system that automatically controls the degree of rotational wheel slip during braking by: (1) Sensing the rate of angular rotation of the wheels; (2) Transmitting signals regarding the rate of wheel angular rotation to one or more controlling devices that interpret those signals and generate responsive controlling output signals; and (3) Transmitting those controlling signals to one or more modulator devices that adjust brake actuating forces in response to those signals.

An auto-reverse system enables power windows and sunroofs on motor vehicles to automatically reverse direction when such power windows and panels detect an obstruction. This feature can prevent children and others from being trapped, injured, or killed by the power windows and sunroofs.

ESC is a computerized technology that improves a vehicle's stability by detecting and reducing loss of traction (skidding). When ESC detects loss of steering control, it automatically applies the brakes to help steer the vehicle in the driver's intended direction. Braking is automatically applied to wheels individually, such as the outer front wheel to counter oversteer, or the inner rear wheel to counter understeer. Some ESC systems also reduce engine power until control is regained.

An EDR is a device installed in motor vehicles to record technical vehicle and occupant information for a brief period before, during, and after a triggering event, typically a crash or near-crash event. Sometimes referred to as "black-box" data, these data or event records can be valuable when analyzing and reconstructing crashes.

A keyless ignition system permits starting a car without a physical key being inserted into an ignition. Instead, a small device known as a "key fob" transmits a code to a computer in the vehicle when the fob is within a certain close range. When the coded signal matches the code embedded in the vehicle's computer, a number of systems within the car are activated, including the starter system. This allows the car to be started by simply pressing a button on the dashboard while the key fob is left in a pocket or a purse. The vehicle is usually shut down by pushing the same button.

A TPMS is an electronic system designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. TPMS can be divided into two different types - direct and indirect. Direct TPMS employ pressure sensors on each wheel, either internal or external. The sensors physically measure the tire pressure in each tire and report it to the vehicle's instrument cluster or a corresponding monitor. Indirect TPMS does not use physical pressure sensors but measure air pressures by monitoring individual wheel rotational speeds and other signals available outside of the tire itself.

When the traction control computer detects a driven wheel or wheels spinning significantly faster than another, it invokes an electronic control unit to apply brake friction to wheels spinning due to loss of traction. This braking action on slipping wheels will cause power transfer to the wheels with traction due to the mechanical action within the differential.

An ACN system notifies emergency responders that a crash has occurred and provides its location.

A backup camera, also known as a rearview video system, helps prevent back-over crashes and protects our most vulnerable people - children and senior citizens - by providing an image of the area behind the vehicle. A backup camera helps the driver see behind the vehicle while in reverse.

A rear cross traffic alert system warns the driver of a potential collision, while in reverse, which may be outside the view of the backup camera.

A CIB system is an automatic emergency braking system designed to detect an impending forward crash with another vehicle. CIB systems automatically apply the brakes in a crash imminent situation to slow or stop the vehicle, avoiding the crash or reducing its severity, if the driver does not brake in response to a forward collision alert.

A DBS system is an automatic emergency braking system designed to detect an impending forward crash with another vehicle. DBS systems automatically supplement the driver's braking in an effort to avoid a crash if the driver does not brake hard enough to avoid it.

An FCW system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles. If the vehicles get too close due to the speed of either vehicle, the FCW system will warn the driver of the rear vehicle of an impending crash so that the driver can apply the brakes or take evasive action, such as steering, to prevent a potential crash. FCW systems provide an audible, visual, or haptic warning, or any combination thereof, to alert the driver of an FCW-equipped vehicle of a potential collision.

A PAEB system provides automatic braking for vehicles when pedestrians are in front of the vehicle and the driver has not acted to avoid a crash.

BSW alerts drivers with an audio or visual warning if there are vehicles in adjacent lanes that the driver may not see when making a lane change.

An LDW system monitors lane markings and alerts the driver if their vehicle drifts out of their lane without a turn signal or any control input indicating the lane departure is intentional. An audio, visual or other alert warns the driver of the unintentional lane shift so the driver can steer the vehicle back into its lane.

An LKA system prevents a driver from unintentionally drifting out of the intended travel lane. LKA systems use information provided by Lane Departure Warning (LDW) system sensors to determine whether a vehicle is about to unintentionally move out of its lane of travel. If so, LKA activates and corrects the steering, brakes or accelerates one or more wheels, or does both, resulting in the vehicle returning to its intended lane of travel.

DRL is an automotive lighting system on the front of a vehicle or bicycle, that automatically switches on when the vehicle is in drive, and emits white, yellow, or amber light to increase the conspicuity of the vehicle during daylight conditions.

A headlamp light source provides a distribution of light designed to provide adequate forward and lateral illumination with limits on light directed towards the eyes of other road users, to control glare. This beam is intended for use whenever other vehicles are present ahead. Halogen, high-Intensity discharge (HID), light-emitting diode (LED), and laser are the most common headlights on the market.

A semi-automatic headlamp beam switching device provides automatic or manual control of beam switching at the option of the driver. When the control is automatic, the headlamps switch from the upper beam to the lower beam when illuminated by the headlamps on an approaching car and switch back to the upper beam when the road ahead is dark. When the control is manual, the driver may obtain either beam manually regardless of the condition of lights ahead of the vehicle.

Engine displacement (in cubic centimeters) is the volume swept by all the pistons inside the cylinders of a reciprocating engine in a single movement from top dead center to bottom dead center.
