Apparatus and method for determining mounting state of electronic control unit of electronically controlled suspension system

A method for determining a mounting state of an electronic control unit (ECU) of an electronic controlled suspension (ECS) system including a plurality of dampers individually provided on respective wheels of a vehicle, a wheel acceleration sensor provided on each front wheel of the vehicle, and the ECU having a vertical acceleration sensor built in an interior thereof and controlling each of the dampers, the method comprising the steps of:

• calculating, by a signal processor of the ECU, a damper velocity of each of the dampers;
• calculating, by an integrator of the ECU, an integral of the damper velocity by integrating the damper velocity of each of the dampers per unit time;
• and
• comparing, by a comparator of the ECU, the integral of the damper velocity with an actual stroke of each of the dampers to determine a mounting state of the ECU.

A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:

• program instructions that calculate a damper velocity of each of a plurality of dampers;
• program instructions that calculate an integral of the damper velocity by integrating the damper velocity of each of the dampers per unit time;
• and
• program instructions that compare the integral of the damper velocity with an actual stroke of each of the dampers to determine a mounting state of an electronic control unit (ECU) of an electronic controlled suspension (ECS) system.
