An electronic device and a method for determining whether a vehicle suspension system has degraded by positioning the electronic device in a vehicle includes activating a camera to initiate data capture within the electronic device. The camera is positioned to capture a change in a field of view during vehicle operation. The method includes calculating a vehicle suspension operating characteristic based on information captured by the camera and determining whether the calculated vehicle suspension operating characteristic exceeds a threshold. A signal indicative of suspension degradation is output when the threshold is exceeded.

A vehicle behavior control apparatus comprises first to fourth suspensions provided on first to fourth wheels of a vehicle, respectively. The first to fourth suspensions include first to fourth actuators that apply vertical control forces to the first to fourth wheels, respectively. When a failure occurs in the fourth actuator other than the i-th actuator (i=1 to 3) among the first to fourth actuators, the vehicle behavior control apparatus executes the following first to third process. The first process is calculating a required value of a behavior parameter representing a behavior of the vehicle. The second process is converting the required value into an i-th required control force for the i-th actuator. The third process is controlling the behavior of the vehicle by controlling the i-th actuator based on the i-th required control force.
