Too much throttle on a steep climb can cause wheelspin. Too little, and the vehicle may struggle to move. On narrow trails, turning around can take several manoeuvres. And on cross-axle terrain, a wheel losing contact with the ground can make it harder for the vehicle to keep moving.

These are some of the challenges WBTL's off-road control functions are designed to address.

Developed around WBTL's WCBS brake-by-wire system, these functions include Crawl Control (CCO), Tank Turn (TAB) and the All-Terrain Control System (ATS).

Crawl Control (CCO)

On steep climbs and descents, CCO helps maintain a set low speed without requiring constant accelerator and brake adjustments.

Drivers can set a target speed using the control switch, or adjust it through the accelerator and brake pedals. The system dynamically regulates drive and braking forces according to the vehicle's driving conditions, helping maintain a relatively stable speed.

Tank Turn (TAB)

When turning space is limited, TAB helps reduce the vehicle's turning radius.

Once CCO is activated and the required conditions are met, the system applies braking force to the inner rear wheel and controls its wheel slip, reducing the wheel's speed to assist with tighter turns.

All-Terrain Control System (ATS)

Different terrain conditions call for different control strategies. ATS provides dedicated strategies for different terrain modes.

WBTL is also developing road-surface recognition technology. A vision module identifies the road surface and passes this information to the brake control system, which can then adjust ABS and TCS parameters accordingly. This allows braking and traction control parameters to be better suited to different road surfaces.
