NEXON BSVI MCE - SERVICE MANUAL

ELECTRONIC STABILITY CONTROL INTEGRATED PROGRAM (ESCi) 6 UNDERSTEER CORRECTION Understeer is when the vehicle pushes straight ahead rather than turning in the direction intended by the driver. The system will react to under steer by braking the inner rear wheel. This creates a reactive force to stabilise the vehicle and keep it on course. Over steer is the opposite, i.e. when the vehicle turns in much more than intended by the driver. The system will react to over steer by braking the outer front wheel. OVERSTEER CORRECTION Over steering is defined as a situation in which the vehicle yaw rate exceeds the target yaw rate given by the driver (as a result of steering wheel Angle input). The purpose of the function is to detect a deviation of the vehicle's yaw rate from the target yaw rate and react accordingly, applying Individual wheel brakes to create a counteracting moment around the z- axis of the vehicle. This counteracting moment is created by braking the Rear outside and if necessary, the front outside wheel. NOTE When a vehicle is taking a right turn the right side wheels are called inner wheel and the left are called outer wheels. Similarly when taking a left turn the left wheels are called inner wheels and right wheels are called outer wheels. ESCi brake control might also be combined with reductions in the engine torque if necessary. When ESCi or TCS is active the warning lamp will flash as an indication to the driver. During control the driver may feel the engine power reduce or the individual brakes being applied. The system will support the driver within the boundaries of the vehicle and environmental physical limits. The ESCi cannot prevent accidents that are the result of excessive speed.
