Volvo Enhanced Stability Technology

VHD vocational trucks built for concrete mixer duty are now standard with Volvo Enhanced Stability Technology (VEST) to reduce the possibility of rollovers in the high-center-of-gravity vehicles. Made by Bendix, VEST uses the truck's anti-lock braking system and traction control to monitor wheel speeds and compare them with other dynamic motions in the chassis and, if necessary, reduce power and apply individual brakes to lessen the chance of rollovers. VEST uses sensors to determine steering angle, lateral acceleration, and pressure in the rear suspension's air bags to measure driver input and vehicle response in changing situations.
