4.5.1. Power
The BSD Sensor will be powered by the ignition(only powered when ignition is on).
4.5.2. Ground
Ground offsets of up to 0.5V should be expected between modules.
4.5.3. CAN
VRS shall provide CAN serial data interface hardware for electrical integration
testing. All electrical requirements related to CAN are specified in item 2.3.2. The
OEM is responsible to support the CAN development and provide access to the
CAN tools the sensor needs to interface with.
4.5.4. Operating current
The operating current is specified in table 15.
4.5.5. HMI driver
The OEM is responsible for the HMI. The two channels HMI driver per sensor
module is realized by using intelligent high side switches designed to drive two
LED arrays with common ground.
4.6. Maintenance and repairing
Proper orientation of the BSD module must be guaranteed by the dealer after
repair. After a crash affecting the vehicle body, the car body should be repaired to
guarantee a maximum misalignment of the sensor of ±2°.
The BSD system shall not require scheduled maintenance or service during its
target life.
