Overview of the System Environment
The SPAS (Smart Parking Assist System) is part of a customer system providing the PAS and the SPAS functionality to the driver.
The SPAS system is a generic, sophisticated subsystem. Therefore the intention is that every SPAS application shall use this subsystem.
Primary Functions
The system identifies parallel parking slots suitable to back-in the vehicle by analyzing the distance data provided by the SPAS sensors.
When a suitable parking slot has been identified the SPAS system leads the vehicle into the parking slot by operating the steering while the driver operates acceleration pedal, clutch (gearshift) and brake.
During parking manoeuvre, a contact from the wheel to the curb is possible, however the system was designed to reduce the occurance for such case. If this case the driver should drive in the opposite direction to continue the parking manoeuvre.
