The invention provides a detection device and vehicle-mounted equipment, and relates to the technical field of electronics. According to the invention, the abnormal operation state of the SoC can be detected. The detection device comprises a detection module, a notification module and a first capacitor unit, wherein the output end of the detection module is connected with the first capacitor, and the first capacitor is further connected with the input end of the notification module; the detection module is used for responding to the target edge signal appearing at the input end of the detection module, and charging the first capacitor unit through the output end of the detection module within a preset time period after the target edge signal appears, wherein the first capacitor unit discharges under the condition that the first capacitor unit is not charged; the notification module is used for detecting the voltage at the two ends of the first capacitor, setting the output end of the notification module to be in a first state when the voltage at the two ends of the first capacitor is greater than the threshold voltage, and setting the output end of the notification module to be in a second state when the voltage at the two ends of the first capacitor is smaller than the threshold voltage. The detection device is applied to fault detection.
