| ACC Laser Radar |
 |
DENSO’s Adaptive Cruise Control System (ACC) uses a long-life laser radar which precisely recognizes preceding vehicles using two-dimensional laser scanning.
How it works:
- The laser radar emits a laser toward a preceding vehicle.
- The laser radar detects light reflected from the vehicle ahead.
- It converts the light into electrical signals.
- It calculates the vehicle’s position including distance and angle.
Benefits and Features
- Wider scanning range and less false detection
- Rotating a polygon mirror with different surface incline angles allows two-dimensional laser scanning at a wide horizontal angle – ± 18 degrees at most.
- Long life and small size
- DENSO-developed laser diode and reduced sensor window size mean the laser radar is smaller and lasts longer.
- Measurement over long distances to preceding vehicles
- The DENSO-developed laser diode produces the world’s largest laser power – 34 watts, allowing measurement of longer distances.
- Precise measurement of the distance to preceding vehicles
- Large scale integrated (LSI) circuit, with newly developed time measurement capabilities, achieves a time measurement of 0.5 nanoseconds (5×10-10 seconds). This means the laser radar, using the LSI circuit, can detect, with an error rate of only a few centimeters, the distance to a vehicle 100 meters ahead.
