XPilot Driving intelligent driving system
10. Super Adaptive Cruise Control (Super ACC)
• Adaptive Cruise Control
- Product definition
The adaptive cruise control system can help the driver to realize the automatic acceleration and deceleration of the vehicle while maintaining a sufficient safe distance from the vehicle in front
- Function Description
When ACC is enabled, the driver only needs to maintain control of the steering wheel and respond to emergency situations, and the system will automatically take over the execution of acceleration and braking, and supports Stop & Go;
Compared with constant speed cruise, adaptive cruise is a more intelligent cruise assisted driving. Through MRR and front visual recognition system, it can automatically control the vehicle speed or Stand still and drive while keeping a safe distance;
After ACC is activated, overlap with FCW and AEB in non-emergency situations should be avoided, that is, during ACC takeover, under normal acceleration and deceleration conditions (non-jammed vehicle insertion, non-target objects suddenly breaking into the sensor field of view), FCW and triggering of AEB.
In the ACC state, the driver can still use the accelerator pedal to intervene the vehicle to accelerate the vehicle. At this time, the acceleration speed is not limited by the maximum cruising speed, but when the driver releases the accelerator pedal, the vehicle will still return to the maximum cruising speed. Adaptive cruise.
If the driver intervenes on the accelerator pedal to control the vehicle speed to a speed greater than or equal to 160km/h, based on the current functional safety assessment, ACC will automatically exit.
There are two independent settings in the ACC system:
(1) Maximum cruising speed
(2) Relative distance following the vehicle
The relative distance following the vehicle refers to the distance between the vehicle in front and the vehicle ahead with reference to the current speed.
The following distance is divided into 5 levels, the default level is 3, and the function memory is required. The adjustment of the following distance requires status feedback on the instrument.
When the following distance is set to level 1, this
