Meritor WABCO Vehicle ControlSystems’ has received an award for a technology designed to prevent truck rollovers, one of the biggest threats to the safety of drivers. The company’s Roll Stability Control (RSC) for tractors and trucks has won the 2003 Technical Achievement Award from the Truck Writers of North America (TWNA). “As pioneers in vehicle control systems, we are pleased to be at the development forefront of progressive technologies such as these,” said Dennis Sandberg, president of Meritor WABCO Vehicle Control Systems. The advanced system is designed to provide intervention to help prevent a rollover situation. The RSC system focuses on a vehicle’s centre of gravity and the lateral acceleration limit or rollover threshold. When that limit is reached, the system intervenes to slow the vehicle by controlling the engine, retarder and automatically activating the drive axle and trailer brakes. An accelerometer mounted directly to the anti-lock braking system (ABS) electronic control unit (ECU) monitors the vehicle’s lateral acceleration. RSC constantly monitors driving conditions and intervenes if critical lateral acceleration is detected.
