DYNAMIC RADAR CRUISE CONTROL SYSTEM


  1. OUTLINE


    1. The dynamic radar cruise control system has 2 cruise control modes: Constant Speed Control Mode, and Vehicle-to-vehicle Distance Control Mode.

    2. The cruise control main switch is used for switching between the 2 modes.

      Mode Outline
      Constant Speed Control Mode

      The constant speed control mode is the same as a conventional cruise control system. However, the differences are as follows:


      • Set speed: 40 km/h (25 mph) → 50 km/h (30 mph).
      Vehicle-to-vehicle Distance Control Mode

      In vehicle-to-vehicle distance control mode, the system recognizes and determines the lane in which the driver's own vehicle and the vehicle ahead are traveling. Thus, the system is able to maintain the proper vehicle-to-vehicle distance in accordance with the vehicle speed, and allows the vehicle to be driven under follow-up control.


      • The driver can operate the distance control switch on the steering wheel to select the vehicle-to-vehicle distance in 3 stages: long, middle and short.

      • This mode consists mainly of 4 controls: constant speed control, deceleration control, follow-up control and acceleration control.

      • Throttle control and brake control achieve smooth deceleration.

    3. In vehicle-to-vehicle distance control mode, the illustrations below show control examples while the driver's own vehicle is operating at 100 km/h (62 mph), and the vehicle ahead is operating at 80 km/h (50 mph).
