Circuit Description
WARNING: This page is about a different car, the 2003 Lexus LS 430. However, it is still accessible from the selected car via links, so may be relevant.
Based on data from the laser radar sensor, the distance control ECU determines a vehicle to Follow and transmits the acceleration and deceleration signal for achieving the target distance. The distance control ECU sends the shift down request signal to the ECM, and sends the brake control request and alarm request signals through the ECM to the skid control ECU.
