Load-Bearing Capacity
Metrics: Maximum Gross Mass (including vehicle curb weight and cargo weight)
Standards: Determined based on the vehicle model and design requirements; typically required to meet the maximum limits stipulated by national or industry standards.
Braking Performance
Metrics: Braking distance, braking deceleration, thermal fade resistance, etc.
Standards: Braking distance must fall within the specified range; braking deceleration should be stable and sufficiently high; thermal fade resistance must be robust-meaning the vehicle maintains effective braking performance even after prolonged, continuous braking.
Driving Stability
Metrics: Rollover threshold, lateral acceleration, etc.
Standards: A high rollover threshold indicates that the vehicle is less prone to rolling over during high-speed driving or cornering; lateral acceleration must be controlled within a safe range to ensure a smooth ride.
Suspension System Performance
Metrics: Suspension stiffness, damping characteristics, ground clearance, etc.
Standards: Suspension stiffness should be moderate-balancing passenger comfort with sufficient structural support; damping characteristics should be optimized to minimize the impact of vibrations on the cargo; ground clearance must be sufficient to prevent the chassis from scraping the ground.
Steering Agility
Metrics: Minimum turning radius, steering angle, etc.
Standards: A small minimum turning radius facilitates flexible maneuvering in confined spaces; a wide steering angle enhances the vehicle's overall maneuverability and adaptability.
Fuel Economy
Metrics: Fuel consumption per 100 kilometers
Standards: Varies depending on actual operating conditions and the specific vehicle model, but fuel consumption should be minimized whenever possible to maximize transport efficiency.
Safety
Metrics: Collision protection capability, clarity of reflective markings, emergency braking systems, etc.
Standards: The vehicle must possess robust collision protection capabilities; reflective markings should be clear and highly visible to enhance driving safety at night; the vehicle should be equipped with active safety measures, such as emergency braking systems.
