Electronically controlled brake (ECB) developed by Toyota Motor Corporation initially for its hybrid and Lexus models, is the world's first production brake-by-wire braking system. [1] The ECB went on sale in Japan in June 2001, [2] first appearing on the Toyota Estima hybrid (first generation), [3] and making its North American debut with the launch of the Lexus RX 400h SUV in April 2005. The ECB is an integral part of the company's Vehicle Dynamics Integrated Management stability control system, by allowing for automatic brake adjustments, which work in conjunction with variable gear-ratio electric power steering systems.

<span class="mw-page-title-main">Intelligent Parking Assist System</span> Automatic parking system by Toyota

Intelligent Parking Assist System (IPAS), also known as Advanced Parking Guidance System (APGS) for Toyota models in the United States, is the first production automatic parking system developed by Toyota Motor Corporation in 1999 initially for the Japanese market hybrid Prius models and Lexus models. The technology assists drivers in parking their vehicle. On vehicles equipped with the IPAS, via an in-dash screen and button controls, the car can steer itself into a parking space with little input from the user. The first version of the system was deployed on the Prius Hybrid sold in Japan in 2003. In 2006, an upgraded version debuted for the first time outside Japan on the Lexus LS luxury sedan, which featured the automatic parking technology among other brand new inventions from Toyota. In 2009, the system appeared on the third generation Prius sold in the U.S. In Asia and Europe, the parking technology is marketed as the Intelligent Park Assist System for both Lexus and Toyota models, while in the U.S. the Advanced Parking Guidance System name is only used for the Lexus system.

<span class="mw-page-title-main">Hybrid electric vehicle</span> Type of hybrid vehicle and electric vehicle

A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system. The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There is a variety of HEV types and the degree to which each function as an electric vehicle (EV) also varies. The most common form of HEV is the hybrid electric car, although hybrid electric trucks, buses, boats and aircraft also exist.

<span class="mw-page-title-main">Driver monitoring system</span> Vehicle safety system

The driver monitoring system, 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.

<span class="mw-page-title-main">Vehicle Dynamics Integrated Management</span> Vehicle handling system by Toyota

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.

<span class="mw-page-title-main">Active Stabilizer Suspension System</span>

Active Power Stabilizer Suspension System (APSSS), is an electric active suspension system with active anti-roll bars developed by Toyota Motor Corporation for its high-end vehicles including Lexus models. By altering stabilizer bar stiffness, this system acts to reduce body tilt during cornering, keeping the vehicle more level during turns and improving handling, as opposed to the natural tendency of a vehicle to roll due to the lateral forces experienced during high-speed maneuvering. The active stabilizer system relies on vehicle body sensors and electric motors. The first production usage of this system was introduced in August 2005 with the Lexus GS430 sport sedan, followed by the 2008 Lexus LS 600h luxury sedan. The development of APSSS is claimed to be the world's first electric active stabilizer system. It is a system improvement of an earlier Toyota technology called Toyota TEMS (Toyota Electronic Modulated Suspension).

It has also been labelled as "Recreational Cross Country" in some markets. The RX's current Toyota counterpart is the Highlander/Kluger; past counterparts included the Harrier and Venza.

E-Four, eFour, AWD-i, or AWD-e was developed by Toyota. Front wheels are powered directly by the hybrid powertrain, rear wheels are powered by a dedicated electric motor with its own power control unit, reduction gear and differential. Amount of torque transferred to the rear wheels is automatically adjusted by the vehicle's electronic control unit according to driving conditions. E-Four also adds additional regenerative braking. In North America, Toyota uses the term AWD-i. There is no drive shaft between the front combustion engine and rear wheels. The rear wheels only receive power and torque from the rear electric motor(s).
