ESC incorporates yaw rate control into the anti-lock braking system (ABS). Anti-lock brakes enable ESC to slow down individual
wheels. The ESC systems also incorporate a traction control system which senses drive-wheel slip under acceleration and individually
brakes the slipping wheel or wheels and/or reduces excess motor power until control is regained. However, ESC serves a different
purpose from that of ABS or traction control.
The ESC system uses several sensors to determine where the driver intends to travel. Other sensors indicate the actual state of the
vehicle. The control algorithm compares driver input to vehicle response and decides, when necessary, to apply brakes and/or reduce
throttle by the amounts calculated.
Steering components include:
• A steering wheel angle sensor that determines where the driver wants to steer.
• A yaw rate sensor that measures the rotation rate of the bus. The data from the yaw sensor is compared with the data
from the steering wheel angle sensor to determine regulating action.
• A lateral acceleration sensor that measures the vehicle's lateral acceleration. This is often called an accelerometer.
• A wheel speed sensor that measures the wheel speed.

WARNING!
WARNING!
The driver is ALWAYS responsible for the control and safe operation of the bus at any time.
The Antilock Braking System (ABS) or Electronic Stability Control (ESC) system(s) does not replace the need for
a skilled, alert, professional driver reacting appropriately and in a timely matter. Safe driving practices must be
followed at all times.
