Vehicle Skid Control (VSC) is now available on six Toyota Division models. Toyota developed a VSC system that relies on electronics to help control a vehicle when a loss of traction is imminent. Toyota offers VSC as standard equipment on Land Cruiser, Sequoia and 4Runner sport/utility vehicles. VSC is also offered as optional equipment on Sienna minivan, Avalon full-size sedan and the all-new Highlander SUV. A large number of single-vehicle accidents are caused by the loss of traction under lateral skidding conditions. VSC senses the onset of traction loss and helps the driver stay on track. This is achieved via the system’s ability to reduce engine power and to control the brake actuator. While other Toyota systems, such as anti-lock brakes (ABS) and traction control (TRAC), work to help prevent straight-line skids, VSC helps to avoid the loss of control up to the physical limits of the traction available under lateral skidding conditions. The VSC system harnesses the ABS and TRAC sensors, actuators, and computer electronics to help the driver avoid vehicle skids and spins. Using input from four wheel-speed sensors, a directional sensor, a deceleration sensor and a steering wheel angle sensor, the VSC computer uses engine throttle control and individual wheel braking to help counteract skidding and spinning. The VSC system also includes a slip indicator with a warning sound and light to alert the driver that the tires are about to exceed the grip limit. Additional vehicles in the Toyota model lineup will receive VSC technology in the future.
