For tandem axle from 2201 to 2800 kg. The intelligent Dive Control System from BPW can be retrofitted at all BPW in connection with the overrun device (type ZAF-2 and ZAF-3) without any problems. An intelligent emergency system. Comparing with the ESP system for cars, the iDC gets the trailer immediately back on track in the event of critical lateral acceleration. The trick is that the braking is not controlled by the car but directly by the iDC, which is a part of the Safety Braking unit. So the towing vehicle and the trailer are completely automatically stabilised. The iDC detects dangerous situations in good time and automatically intervenes before a dicey situation arises. An intervention from you to intercept if it starts rolling ? for instance by counteracting ? is no longer necessary. Enjoy carefree caravaning with the iDC. Maintenance free. Weight only approx. 6 kg.
