1. Applicable scenario analysis

(1) Fixed route transportation in mining areas/construction sites

Scene characteristics: Mining dump trucks often travel back and forth along fixed routes in mining areas or large construction sites (such as mining points → crushing stations → material yards), with poor road conditions but high path repeatability.

Cruise Value: Activate cruise control on longer flat roads (such as main roads in mining areas) to reduce driver throttle fatigue. By maintaining the economic speed (such as the low-speed and high torque range of diesel engines), fuel consumption can be reduced (optimized by 5% -10%).

(2) Characteristics of closed site transportation scenarios for dump trucks: dump trucks on urban construction sites drive at low speeds (such as below 30km/h) in closed sites and need to start and stop frequently. Cruise adaptation: Customize low-speed cruise mode (such as 15-30km/h), combined with automatic start stop function, to reduce the operational burden during short distance transportation.

2. Technical adaptation requirements

(1) Optimization of load compensation function under heavy load conditions: The difference in weight between unloaded and fully loaded dump trucks is large (such as 60 tons → 100 tons), and the cruise system needs to monitor the load in real time and adjust the throttle response to avoid insufficient power or overspeed on uphill slopes. Steep slope logic: In mining areas with large slope changes, integrated predictive cruise control (PCC) is used to predict terrain and downshift or limit vehicle speed in advance.

(2) Adaptive anti vibration and dust-proof design for harsh environments: Traditional cruise sensors require enhanced protection to avoid accidental triggering caused by dust and mud. Low adhesion road mode: Automatically limits cruising speed on gravel and muddy roads to prevent slipping.

(3) Disabled during the loading and unloading phase in conjunction with the self dumping function: Automatically exit cruise mode through lifting mechanism signals or GPS positioning (such as near the unloading area) to ensure safe operation.

3. Future development direction

Autonomous driving integration: In smart mines, dump trucks can achieve coordinated and uniform operation of fleets through unmanned driving and global cruise scheduling (such as Rio Tinto's AutoHaul system).

New energy vehicle adaptation: The cruise control system of electric/hydrogen dump trucks is linked with energy recovery, and the maximum feedback braking is triggered through cruise control when going downhill.
