Reversing radar warning, driver’s safety belt warning, front passenger’s safety belt warning, parking brake warning, headlight not close warning are sound warning, warning priority is the sequence above-mentioned, sound loundness: 55±5db.
1. Reversing radar warning Voltage signal, come from reversing radar sensor. 2). Signal management
Obstacle distance (mm) Sound frequency(Hz) Zone Note > 1500 - Safety zone Reversing normally 900~1500 2 Safety zone Reversing normally 600~900 4 Warning zone Reversing decelerate 350~600 8 Danger zone Stop reversing < 350 Ding for a long time Danger zone Stop reversing
3). Signal output Sound signal continuously send out until input signal disappear, sound frequency: 2000±10Hz. Signal source: Drive safety belt indicating light, front passenger’s safety belt indicating light, front passenger’s seat sensor, vehicle speed signal. 2). Signal management Refer to warning control logic in below figure, front passenger’s safety belt warning add the judgment of whether there is person in front passenger’s seat. |
