Product Overview

 Product Description

The products described here are part of a family of radars offered by Veoneer. They are intended for automotive use, operating in the 76-77 GHz band.

The radars are fully integrated devices, with the RF part and DSP part on two different PCBs. The DSP board controls the signal processing, as well as vehicle communications through CAN and diagnosis functions. The RF PCB generates the FMCW waveform and transmits/receives the radio signal through patch antennae.

The radars are integrated into a vehicle to enhance vehicle safety systems. They can be integrated as a standalone sensor or sensors or as part of a more complex system that also may include cameras, lidar, and other types of sensors to provide features like Automatic Cruise Control, Automatic Emergency Break, Free space detections, and other Autonomous Driving functions.

Product Application Examples

The product can be used, but is not limited to the following applications:

• Autonomous drive systems
• Automatic braking systems
• Lane change warning
• Adaptive cruise control
• Collision prevention systems
• Automatic lane change systems
• Pedestrian and Bicycle collision prevention
• Etc.

Typical Installation

The radar is typically installed in the positions of the vehicle depicted in Figure 1 often mounted behind a bumper or emblem.

Hardware Description

The radar assembly consists of 2 PCB boards, one containing all the RF components, antennas, and analog to digital converters, and the other containing all that is necessary for signal processing and communications with the vehicle and power.

The boards are assembled into a plastic housing that is laser welded together. The sensor has no serviceable parts and can’t be opened without permanent damage.

Sensor Features

The product can be used to support the following applications among others:

• Blind Spot Monitoring (BSM) – The BSM algorithm detects and reports “Objects of Interest” on either side of the vehicle, within a specified “blind spot” zone. The feature generates an output signal on the CAN Bus.
• Lane Change Warning/Assist (LCW/A) – The LCW/A algorithm detects and reports to the driver that a highway licensable vehicle is rapidly approaching the host vehicle in one of the adjacent lanes. The feature generates a signal which is used to drive a visual display placed in the outside view mirror and/or request a chime or vibrating seat cushion, to alert the driver to the approach of objects of interest within the defined LCA zone. The signal can also be used by the ADAS system to engage/dis-engage lane change, as per described in UN R79.
• Rear Cross-Traffic Alert/Break (RCTA/B) – The RCTA/B algorithm detects and reports “Objects of Interest” behind the host vehicle, within a specified RCTA/B coverage zone when going backward. The feature generates a signal which is used to drive a visual display to alert the driver of the presence of objects of interest that may cause a collision with the host vehicle within the defined RCTA zone. The signal can also be used to control the break.
