ESP controls during under steering
The ESP system recognizes the directional angle with
the steering wheel angle sensor and senses the slip-
ping route that occurs reversely against the vehicle cor-
nering direction during understeering with the yaw rate
sensor and the lateral sensor. Then the ESP system
applies the brake at the rear inner wheel to com-
pensate the yaw moment value. In this way, the vehicle
does not lose its driving direction and the driver can steer
the vehicle as driver intends.
ESP controls during oversteering
The ESP system recognizes the directional angle with
the steering wheel angle sensor and senses the slip-
ping route that occurs towards the vehicle cornering di-
rection during oversteering with the yaw rate sensor and
the lateral sensor. Then the ESP system applies the
brake at the front outer wheel to compensate the
yaw moment value. In this way, the vehicle does not
lose its driving direction and the driver can steer the
vehicle as he or she intends.
ESP Control
As the single-track vehicle model used for the calculations is only valid for a vehicle moving forward, ESP
intervention never takes place during backup. The ESP system includes the ABS/EBD and ASR systems
allowing the system to be able to operate depending to the vehicle driving conditions. For example, when the brakes
are applied during cornering at the speed of 100 km/h, the ABS system will operate at the same time the ASR or
ABD systems operate to reduce the power from the slipping wheel. And when yaw rate sensor detects the rate
exceeding 4 degree/seconds, the ESP system is activated to apply the brake force to the corresponding wheel to
compensate the yaw moment with the vehicle stability control function.
When various systems operate simultaneously under a certain situation, there may be vehicle control problems due
to internal malfunction of a system or simultaneous operations. In order to compensate to this problem, the ESP
system sets the priority among systems. The system operates in the order of TCS (ASR or ABD), ESP and ABS.
The order may be changed depending on the vehicle driving situations and driving conditions.
