Its contents are not to be exploited, passed on or disclosed to third parties without our express permission. All rights are reserved. LCA 3.5 – Lane Change Assistant Mazda: LCA 3.5 SG1 - M LCA 3.5 SG2 – M GM: LCA 3.5 SG1 - GM LCA 3.5 SG2 - GM System Function and Purpose The LCA is an advanced driver assistant system, to warn the driver of the subject vehicle against potential collisions with vehicles to the side and/or to the rear of the subject vehicle, and moving in the same direction as the subject vehicle during lane change manoeuvres. The system therefore detects vehicles to the rear and sides of the subject vehicle. When the subject vehicle driver indicates the desire to make a lane change, the system will evaluate the situation and warn the driver if a lane change is not recommended. LCA is not meant to encourage aggressive driving. The absence of a warning will not guarantee that the driver can safely make a lane change manoeuvre. The system will not take any automatic action to prevent possible collisions. Responsibility for the safe operation of the vehicle remains with the driver. LCA System Architecture Hella 3399EN (2000-05) The LCA consists of two radar sensor units which are mounted behind the rear bumper in the left and right rear corners of a car so that the rear and the sides of the car can be observed. One of the units is the main control unit "master" and the other is the "slave". The two units interchange data between each other via the sensor CAN-bus. The master interchanges data with other electronic control units of the vehicle via the vehicle CAN-bus. Both units incorporate an RF part and a DSP to perfom the radar signal processing. Only the master incorporates a microprocessor which handles the communication to the vehicle CANbus. The warning lamps for the left and the right side are connected to the slave. signed by: checked by: Date: 2014-11-11 Subject: No.: LCA 3.5 – Lane Change Assistant Hella KGaA Hueck & Co.

Page 3 of 4 59552 Lippstadt The RF parts each consist of • one 24-GHz-VCO, • one transmit antenna and • three receivers (each consisting of antenna, LNA, mixer, BPF and base-band amplifier). Vertraulich. Weitergabe sowie Verwertung und Mitteilung des Inhalts ist nur mit unserer ausdrücklichen Genehmigung gestattet. Alle Rechte vorbehalten. The transmit signal is generated by the 24-GHz-VCO. The 24-GHz-VCO is frequency modulated by a modulation control circuit and the DSP. A frequency divider is used to align the modulation of the 24-GHz-VCO and to keep it within the frequency band limits. The transmit antenna is a microstrip patch antenna array with 1x8 elements. It is designed to illuminate the rear and the side of the vehicle and is thus a medium gain antenna. The receivers down-convert the receive signals directly to zero-IF by using the 24-GHz-VCO signal. The base-band receive signals are digitized by ADCs in the DSP. The receive antennas are microstrip patch antennas which also have a medium gain (1x8 elements).
