Introduction to the 2015 Audi A3 Systems
The 2015 Audi A3 sets new standards in the premium compact segment by integrating advanced driver assistance systems, previously found in luxury-class vehicles. This document provides an overview of these innovative technologies, including the Audi side assist, Audi active lane assist, and adaptive cruise control (ACC).
Key Driver Assistance Features
- Audi side assist: Supports drivers during lane changes by monitoring the blind spot and the area to the rear of the vehicle using radar sensors. A visual warning is provided via an LED in the door mirror housing.
- Audi active lane assist: Detects lane markings using a camera and provides subtle steering interventions to help keep the vehicle within its lane, especially when the turn signal is not activated. This system operates at speeds above 40 mph (65 km/h).
- Adaptive Cruise Control (ACC): A radar-based system that maintains a set distance to the vehicle ahead by automatically adjusting acceleration and braking within a speed range of 18-93 mph (30-150 km/h). The system can be further enhanced with an assistance package, extending its operational range to 125 mph (200 km/h).
Vehicle Electronics Overview
The document also details the vehicle's electronic architecture, including control modules such as the Instrument Cluster Control Module (J285), Vehicle Electrical System Control Module (J519), and various door control modules. It explains the connectivity via CAN and LIN buses and the functions of components like the immobilizer system and power window controls.
