1. General description
T21 reversing radar assist system employs the ultrasonic technology.
This device can remind the driver of the distance between the car rear end and any object, and
give sound prompt to minimize injuries or damages.
System composition:
Radar control module (ECU)
4 rear probes (ultrasonic sensor)
Associated components:
Ignition switch, reversing switch, BCM and instrument.
The ignition switch provides the system power;
The reversing switch provides the system activation signal;
BCM acts as a bridge among the instrument, reversing switch and radar control module;
As the terminal of the system, the instrument provides voice warning and indicates the
distance.
The radar control module transfers the distance from the barrier and its location to BCM via
the LIN bus, and then BCM will transfer the data to the instrument for indication and sound
prompt via the CAN bus.
The LIN communication protocol is upgraded to T21 LIN_V1.3 ISSUE at the transmission
rate of 9.6kBits/s.
