Driver Assistant Systems

Smart Cruise Control (SCC)

Smart Cruise Control is a driver convenience feature that uses radar to detect a vehicle ahead and automatically speeds up or slows down to maintain a safe distance. When there is no vehicle ahead, SCC maintains the preset speed automatically. If a slow-moving vehicle appears ahead, SCC reduces speed to maintain a safe distance.

Lane Keeping Assist System (LKAS)

The Lane Keeping Assist System detects the danger when a vehicle drifts out of its lane while the driver dozes off at the wheel and keeps the vehicle in its lane by controlling the steering wheel.

The LKAS uses a camera mounted on the windscreen to recognise lane markings and the current location. If the vehicle drifts out of its lane without the driver having turned on the indicator, appropriate steering torque is applied to help the driver keep the vehicle in its lane.

Traffic Sign Recognition (TSR)

The Traffic Sign Recognition System is a driver convenience feature that recognises speed limit signs from images of the road captured on a camera on the front of the vehicle. The system relays the speed limit information to the driver.

  • Prevents speeding by recognising speed limit signs on the road day and night
  • Uses CMOS image pattern recognition technology to output from CMOS image sensor (detects traffic sign location and determines type)
  • Uses an I/F signal from the vehicle to compare the current speed and send out a warning if it is excessive (example of system application)
  • Can later be combined with the brake system to enhance automatic speed control system (to prevent speeding)
  • Performs self-diagnosis and data transfer using CAN communication
