All Terrain Progress Control (ATPC)

All Terrain Progress Control

? Product Description

All Terrain Progress Control  is a world-first off-road driving technology developed by Land Rover . ATPC is designed to reduce driver workload and enhance Land Rover’s
world-renowned off-road capability. By taking over throttle and brake control, it allows the driver to concentrate fully on steering and navigating obstacles

? Speed Setting and Cruise Control Operation

• Target Speed Setting: The driver sets a desired speed using the steering wheel-mounted cruise control buttons— just like conventional on-road cruise control.
• Speed Range: Operates at very low speeds between 1.8 km/h and 30 km/h
• Autonomous Operation: Once activated, ATPC requires no pedal inputs from the driver — it automatically manages both throttle and brake applications
• Forward and Reverse: The system works in both forward and reverse gears, making it useful for pulling away from standstill, ascending or descending inclines, and reversing on slippery surfaces

⚡ Traction Management and Vehicle Control

• Automatic Terrain Adaptation: The system works seamlessly with Terrain Response— while Terrain Response tunes the vehicle’s settings for a specific terrain, ATPC maintains a steady speed across it.
• Brake and Throttle Integration: ATPC manages both engine output and braking to maintain the set speed, even on steep gradients, rough terrain, and low-grip surfaces.
• Speed Adjustment: The SET+ and SET- buttons on the steering wheel increase or decrease the target speed within the operating range.
• Resume Function: The RES button resumes the target speed after the driver has used the brakes to slow the vehicle.

? Advanced and Smart Capabilities

Adaptive Off-Road Cruise Control (2025+): An evolution of ATPC now available on the 2025 Land Rover Defender, allowing drivers to set a “comfort level” while the vehicle autonomously handles throttle and braking on rough terrain
Low-Traction Launch: ATPC allows smooth pull-away even on low-friction surfaces such as ice, snow, or wet grass.
