Intelligent Distance Control

By releasing the accelerator pedal, the vehicle decelerates in accordance with the distance to the vehicle ahead and the road.

The Intelligent Distance Control (IDC) system reduces the burden of pedal operation in congested urban areas requiring frequent acceleration and deceleration. When deceleration is needed, the accelerator pedal is released and the brake pedal is operated as necessary.

System operation

1. Vehicle-to-vehicle distance control

The IDC system supports the driver in maintaining an appropriate distance and relative speed with the vehicle ahead by applying the brakes and raising the accelerator pedal.
Representative driving scenarios:

When approaching the vehicle ahead

If the accelerator pedal is released, the system automatically applies the brakes smoothly to decelerate the vehicle and help the driver maintain an appropriate distance.

When the vehicle ahead slows down

Releasing the accelerator pedal will cause the vehicle to decelerate and maintain an appropriate distance when the vehicle ahead slows down. The system also stops the vehicle if the vehicle ahead stops.

2. Navi-link deceleration function^*1

Based on information from the navigation system, the system supports the driver with braking based on the road's path ahead. If the driver is pressing the acceleration pedal, the system can push it back up to help the driver slow the vehicle during cornering.
(When vehicle includes factory installed navigation)

Navigation-cooperative Distance Control Assist

3. Intelligent pedal function^*1

If the driver presses the accelerator pedal while the system is braking, the system generates force to push the accelerator pedal back, helping the driver return the accelerator pedal to the appropriate position.

The system moves the acceleration pedal upwards

System mechanism

The system uses a radar mounted on the front of the vehicle to identify the vehicle ahead and measure the distance and speed difference between the two vehicles.^*2 Based on the measured data, the system decelerates the vehicle as necessary to maintain an appropriate distance.
