Parallel parking is a method of parking a vehicle parallel to the road, in line with other parked vehicles. Parallel parking usually requires initially driving slightly past the parking space, parallel to the parked vehicle in front of that space, keeping a safe distance, then followed by reversing into that space. Subsequent position adjustment may require the use of forward and reverse gears.

Techniques

Parallel parking is considered to be one of the most stressful and difficult skills for new drivers to learn. [1] While parallel parking is a required part of most driving tests, several states in the US have dropped it as a requirement. [2]

Parallel parking enables the driver to park a vehicle in a smaller space than would be true of forward parking. Driving forward into a parking space on the side of a road is typically not possible unless two or more successive parking spaces are empty. Reversing into the spot via the parallel parking technique allows one to take advantage of a single empty space not much longer than the car (in order to complete the parking within three wheel-turns the parking space would generally need to be about one and a half car-length long).

New drivers learn to use reference points to align themselves in relation to the car in front of the space, to determine the proper angle for backing, and to determine when to turn the steering wheel while backing. They may find it easier to briefly stop at each reference point and turn for the next step.

Steps

Two major types of parallel parking technique differ in whether they will use two or three positions of the steering wheel while backing. A skilled driver is theoretically able to parallel park by having their car move along two arcs, the first having its center on the parking side of the car and the second having its center on the other side. There will be a point in the transition between these curves where all the car's wheels will be parallel with each other. Less-confident drivers may choose to drive further while transitioning, making it a pronounced middle step of three. Such a step allows greater tolerances to avoid hitting anything, but forces the car to start further from the road's edge and requires more space to the rear.

Computer Assisted Parallel Parking

Beginning in the early 2000s, automobile manufacturers began providing computer assisted automatic parking software on some models that allowed drivers to engage the software to complete the parallel parking maneuver hands-free. Depending on the system, the automatic parking feature controls the steering while the driver operates the accelerator and brakes, [3] or the software handles both steering and accelerator. [4]

Legality

In Japan, there is a ban on on-street parking, with a few exceptions (such as daytime and evening parking). [5] [6] In addition to this, there is a proof-of-parking rule and motorists are required to present a garage certificate ("Shako shomei sho") to prove that they have a garage before being allowed to register a car. [7] [8] [9] [10]

History

In the 1930s cars were developed with a fifth wheel, in between the two rear wheels and perpendicular to them, which could be lowered to the ground and used to drive sideways into a parallel parking spot. This innovation was intended to make parallel parking much easier, but it never became popular. [11]

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.

In road vehicles, the parking brake, also known as a handbrake or emergency brake (e-brake), is a mechanism used to keep the vehicle securely motionless when parked. Parking brakes often consist of a pulling mechanism attached to a cable which is connected to two wheel brakes. In most vehicles, the parking brake operates only on the rear wheels, which have reduced traction while braking. The mechanism may be a hand-operated lever, a straight pull handle located near the steering column, or a foot-operated pedal located with the other pedals.

<span class="mw-page-title-main">Gear stick</span> Lever used for shifting gears manually

A gear stick, gear lever, gearshift or shifter, more formally known as a transmission lever, is a metal lever attached to the transmission of an automobile. The term gear stick mostly refers to the shift lever of a manual transmission, while in an automatic transmission, a similar lever is known as a gear selector. A gear stick will normally be used to change gear whilst depressing the clutch pedal with the left foot to disengage the engine from the drivetrain and wheels. Automatic transmission vehicles, including hydraulic automatic transmissions, automated manual and older semi-automatic transmissions, like VW Autostick, and those with continuously variable transmissions, do not require a physical clutch pedal.

Vehicular automation is the use of technology to assist or replace the operator of a vehicle such as a car, truck, aircraft, rocket, military vehicle, or boat. Assisted vehicles are semi-autonomous, whereas vehicles that can travel without a human operator are autonomous. The degree of autonomy may be subject to various constraints such as conditions. Autonomy is enabled by advanced driver-assistance systems (ADAS) of varying capacity.

<span class="mw-page-title-main">Automatic parking</span> Autonomous car-maneuvering system

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.

<span class="mw-page-title-main">Automated parking system</span> Robotic system that parks cars

An automated (car) parking system (APS) is a mechanical system designed to minimize the area and/or volume required for parking cars. Like a multi-story parking garage, an APS provides parking for cars on multiple levels stacked vertically to maximize the number of parking spaces while minimizing land usage. The APS, however, utilizes a mechanical system to transport cars to and from parking spaces in order to eliminate much of the space wasted in a multi-story parking garage. While a multi-story parking garage is similar to multiple parking lots stacked vertically, an APS is more similar to an automated storage and retrieval system for cars. Parking systems are generally powered by electric motors or hydraulic pumps that move vehicles into a storage position.The paternoster is an example of one of the earliest and most common types of APS.

<span class="mw-page-title-main">Lane centering</span> Mechanism designed to keep a car centered in the lane

In road-transport terminology, lane centering, also known as lane centering assist, lane assist, auto steer or autosteer, is an advanced driver-assistance system that keeps a road vehicle centered in the lane, relieving the driver of the task of steering. Lane centering is similar to lane departure warning and lane keeping assist, but rather than warn the driver, or bouncing the car away from the lane edge, it keeps the car centered in the lane. Together with adaptive cruise control (ACC), this feature may allow unassisted driving for some length of time. It is also part of automated lane keeping systems.
