ABS ESP

ECU uses wheel speed sensors
to monitor four wheel‑ends to detect wheel‑slip or wheel
lock‑up during braking. The system intervenes when
needed — using Pressure Modulator Valves (PMVs)
to adjust and/or pulse the brake pressure — in order
to optimize the contact between the tires and the road
surface.

ESP EC‑80 Controller analyzes the vehicle's motion
compared to the driver's intended path and provides
Yaw Control (YC) and Roll Stability Program (RSP)
capabilities. When necessary, the system will intervene
to reduce the engine throttle, and/or apply the brakes
at one or more of the wheel ends — to help the vehicle
return to the intended direction.
