Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), 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 where the driver intends to go. 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. ESC does not improve a vehicle's cornering performance; instead, it helps reduce the chance of the driver losing control of the vehicle.
Advanced driver-assistance systems (ADAS) are technologies that assist drivers with the safe operation of a vehicle. Through a human-machine interface, ADAS increase car and road safety. ADAS use automated technology, such as sensors and cameras, to detect nearby obstacles or driver errors, and respond accordingly. ADAS can enable various levels of autonomous driving.
In road-transport terminology, a lane departure warning system (LDWS) is a mechanism designed to warn the driver when the vehicle begins to move out of its lane on freeways and arterial roads. These systems are designed to minimize accidents by addressing the main causes of collisions: driver error, distractions and drowsiness. In 2009 the U.S. National Highway Traffic Safety Administration (NHTSA) began studying whether to mandate lane departure warning systems and frontal collision warning systems on automobiles.
The Mercedes-Benz W221 is a chassis code of the fifth generation S-Class, produced from August 2005 until June 2013. The W221 S-Class was unveiled at the 2005 Frankfurt Motor Show as the successor of the Mercedes-Benz S-Class (W220) and the predecessor of the Mercedes-Benz S-Class (W222).
A hill-holder is a motor vehicle device that holds the brake until the clutch is at the friction point, making it easier for a stationary vehicle to start uphill. By holding the brake in position while the vehicle is put into gear, it prevents rollback. The hill-holder was invented by Wagner Electric and manufactured by Bendix Brake Company in South Bend, Indiana.
Mild hybrids (MHEV) are generally cars with an internal combustion engine (ICE) equipped with a minimally extended battery and an auxiliary electric combined motor and generator in a parallel hybrid configuration that is only enough for an electric-only mode of propulsion at slow speed and allow the engine to be stopped whenever the car is coasting, braking, or stopped, and then restarted once power is required again. Mild hybrids may employ regenerative braking and some level of power assist to the internal combustion engine.
The W212 and S212 Mercedes-Benz E-Class series is the fourth generation of the E-Class range of executive cars which was produced by Mercedes-Benz between 2009 and 2016 as the successor to the W211 E-Class. The body styles of the range are either four-door sedan/saloon (W212) or a five-door estate/wagon (S212). Coupé and convertible models of the E-Class of the same generation are W204 C-Class based and known as the C207 and A207, replacing the CLK-Class coupé and cabriolet. A high-performance E 63 AMG version of the W212 and S212 were available as well since 2009. In 2013, a facelift was introduced for the E-Class range, featuring significant styling changes, fuel economy improvements and updated safety features.
The Mercedes-Benz C216 is the last generation for the grand tourer with name Mercedes-Benz CL-Class, produced from 2006 to 2014. It replaced the C215 platform, and was replaced in 2014 by the C217 S-Class Coupe.
Automatic parking is an autonomous car-maneuvering system that moves a vehicle from a traffic lane into a parking spot to perform parallel, perpendicular, or angle parking. The automatic parking system aims to enhance the comfort and safety of driving in constrained environments where much attention and experience is required to steer the car. The parking maneuver is achieved by means of coordinated control of the steering angle and speed which takes into account the actual situation in the environment to ensure collision-free motion within the available space.
Brake assist or emergency brake assist (EBA) is a term for an automobile braking technology that increases braking pressure in an emergency. The first application was developed jointly by Daimler-Benz and TRW/LucasVarity. Research conducted in 1992 at the Mercedes-Benz driving simulator in Berlin revealed that more than 90% of drivers fail to brake with enough force when faced with an emergency.
Adaptive cruise control (ACC) is a type of advanced driver-assistance system for road vehicles that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead. As of 2019, it is also called by 20 unique names that describe that basic functionality. This is also known as Dynamic cruise control.
The Driver Monitoring System (DMS), also known as driver attention monitor, is a vehicle safety system to assess the driver's alertness and warn the driver if needed and eventually apply the brakes. It was first introduced by Toyota in 2006 for its and Lexus' latest models. It was first offered in Japan on the GS 450h. The system's functions co-operate with the pre-collision system (PCS). The system uses infrared sensors to monitor driver attentiveness. Specifically, the driver monitoring system includes a CCD camera placed on the steering column which tracks the face, via infrared LED detectors. If the driver is not paying attention to the road ahead and a dangerous situation is detected, the system will warn the driver by flashing lights, warning sounds. If no action is taken, the vehicle will apply the brakes. This system is said to be the first of its kind.
R231 is a chassis code for the sixth generation of the Mercedes-Benz SL-Class roadster, replacing the R230. The car was released in March 2012 and uses Mercedes-Benz's new 4.7 litre twin turbo V8 engine with a power output of 435 PS. AMG version of the roadster will follow. The new SL is 140 kg (309 lb) lighter than the previous, being made almost entirely out of aluminium. For the first time, the R231 SL-Class was not available with a non-AMG V12 engined SL 600 model.
A collision avoidance system (CAS), also known as a pre-crash system, forward collision warning system (FCW), or collision mitigation system, is an advanced driver-assistance system designed to prevent or reduce the severity of a collision. In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles, so that it can provide a warning to the driver if the vehicles get too close, potentially helping to avoid a crash. Various technologies and sensors that are used include radar (all-weather) and sometimes laser (LIDAR) and cameras to detect an imminent crash. GPS sensors can detect fixed dangers such as approaching stop signs through a location database. Pedestrian detection can also be a feature of these types of systems.
Sensotronic Brake Control (SBC) is an electro-hydraulic brake system developed by Daimler and Bosch. In this system, the wheel brake cylinders of a vehicle are operated through a servomechanism, offering precise and responsive braking.
An automotive night vision system uses a thermographic camera to increase a driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights. Such systems are offered as optional equipment on certain premium vehicles. The technology was first introduced in the year 2000 on the Cadillac Deville. This technology is based on the night vision devices (NVD), which generally denotes any electronically enhanced optical devices operate in three modes: image enhancement, thermal imaging, and active illumination. The automotive night vision system is a combination of NVDs such as infrared cameras, GPS, Lidar, and Radar, among others to sense and detect objects.
Vehicle Dynamics Integrated Management (VDIM) is an integrated vehicle handling and software control system developed by Toyota. It involves an omnibus computer linkage of traction control, electronic stability control, electronic steering, and other systems, with the intent of improving responsiveness to driver input, performance, and overall safety. The system was first introduced in the Japanese domestic market in July 2004, when Toyota debuted VDIM on the Toyota Crown Majesta. This was followed by the VDIM's export debut on the third generation Lexus GS, which was launched in 2005. VDIM integrates the company's Electronically Controlled Brake (ECB), Anti-Lock Brakes (ABS), Electronic Brakeforce Distribution (EBD), Traction Control (TRC) and Vehicle Stability Control (VSC) active safety systems with the Adaptive Variable Suspension (AVS), Electric Power Steering (EPS) and Variable Gear Ratio Steering (VGRS) systems which previously worked independently using proprietary software. This way all the systems function together rather than the ECU prioritizing which is the most important. VDIM was initially designed for rear-wheel drive cars.
Toyota Concept Vehicles produced between 1990 and 1999 include:
