All Terrain Progress Control

All Terrain Progress Control

📄 Product Description

All Terrain Progress Control is a revolutionary off‑road driving aid from Land Rover. A driver activates All Terrain Progress Control to let the vehicle manage throttle and braking automatically. This system functions as a low‑speed cruise control for challenging terrain. Consequently, the driver focuses entirely on steering and obstacle navigation. The system operates between 1.8 km/h and 30 km/h in both forward and reverse. Therefore, it proves invaluable on steep slopes, slippery surfaces, and rocky trails. Moreover, it works seamlessly with Terrain Response 2 for optimised traction.First, the driver presses the ATPC button on the center console. After that, they set the desired speed using the cruise control buttons. Then the system takes over throttle and brake duties automatically.Subsequently, the vehicle maintains a steady pace regardless of the surface.As a result, the driver negotiates difficult sections with minimal stress. The system also assists with low‑traction launches on ice or snow.

📡 Speed Setting and Cruise Control Operation

The driver sets a target speed using steering wheel cruise control buttons. The system maintains this speed between 1.8 km/h and 30 km/h. Furthermore, it works in both high and low range transfer cases.
Consequently, the vehicle moves at a constant, controlled pace. The system also features a resume function for convenience.

🔄 Activation and Operation Modes

ATPC activates via a dedicated button on the centre console. It defaults to Descent Control Mode when stationary and shifts to Full Function Mode when moving. Moreover, the driver can temporarily override the system with the accelerator. As a result, the vehicle responds immediately to driver inputs. The system also offers hill descent control for steep declines.

⚡ Traction Management and Vehicle Control

The system continuously monitors wheel slip and adjusts power delivery. It works with Terrain Response 2 to optimise traction on all surfaces. Furthermore, it reduces wheelspin on mud, sand, and snow. Consequently, the vehicle maintains forward momentum in difficult conditions. The system also integrates with the vehicle’s electronic stability control.

✨ Key Features

• Low‑speed cruise control for off‑road driving.
• Operates from 1.8 km/h to 30 km/h.
• Works in forward and reverse gears.
• Integrates with Terrain Response 2.
• Automatic throttle and brake management.

📋 Requirements

The vehicle must have a dual‑range transfer box and Terrain Response 2. It also requires the ATPC hardware and software modules. Furthermore, the system works with both automatic and manual transmissions. Most modern Land Rover models offer this feature as an option. Some vehicles may require a software update to enable the function.
