Abstract:
1. A detector for detecting a foreign object caught in a window glass of a vehicle having an engine when the window glass is moved by a power window apparatus that is provided with power supply voltage from the vehicle, the detector comprising: a parameter detection unit for detecting at least one parameter that changes as the power supply voltage to the power window apparatus changes; a determination target value calculation unit, connected to the parameter detection unit, for calculating a determination target value based on the at least one parameter detected by the parameter detection unit; a determination unit for comparing the determination target value with a predetermined determination threshold and determining whether a foreign object has been caught based on a result of the comparison; an engine-stop detection unit for detecting whether the engine of the vehicle is stopped; and a threshold change unit for changing, when the engine-stop detection unit detects that the engine is stopped, the determination threshold so that the probability of the determination unit determining that a foreign object has been caught is lower than that when the engine is being operated.
