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.
Esmond says additional vehicles in the Toyota model lineup will receive VSC technology in the future.
